Impact statement
This study provides novel evidence on the psychological mechanisms underlying anxiety among Lebanese adults by examining the mediating role of fear of happiness in the relationship between intolerance of uncertainty and anxiety. By focusing on a construct that is rarely explored in non-Western contexts, the findings extend existing literature beyond Western populations and highlight the cultural relevance of fear of happiness in settings marked by chronic uncertainty and adversity. Giving the ongoing socioeconomic and political challenges in Lebanon, these results have important clinical and public health implications. Addressing fear of happiness and intolerance of uncertainty through targeted psychological interventions and educational programs may help reduce anxiety symptoms and maladaptive cognitive patterns. Overall, this study underscores the importance of culturally informed mental health research and interventions in high-stress contexts.
Introduction
Anxiety refers to the apprehension of a potential future threat (American Psychiatric Association, 2013; Huang et al., Reference Huang, Wee, Low, Koong, Htay and Fan2021). It is undeniable that anxiety rates among adults across all its levels are higher than ever, sometimes almost reaching 30% of this population (Remes et al., Reference Remes, Brayne, Van Der Linde and Lafortune2016; Mirzaei et al., Reference Mirzaei, Ardekani, Mirzaei and Dehghani2019; Goodwin et al., Reference Goodwin, Weinberger, Kim, Wu and Galea2020; Amu et al., Reference Amu, Osei, Kofie, Owusu, Bosoka and Konlan2021; Kan et al., Reference Kan, Raoofi, Rafiei, Khani, Hosseinifard and Tajik2021). Symptoms of anxiety include a cognitive aspect, such as the anticipation of the worst or a fear of dying or of losing control; an emotional aspect, such as feeling worried, nervous, terrified or unable to relax; and a physiological aspect such as tingling, dizziness, shakiness, heart palpitations or difficulty breathing (Schwartz et al., Reference Schwartz, Davidson and Goleman1978; Beck et al., Reference Beck, Epstein, Brown and Steer1988; Koksal and Power, Reference Koksal and Power1990; Spitzer et al., Reference Spitzer, Kroenke, Williams and Löwe2006; American Psychological Association, 2011; Ganson et al., Reference Ganson, Tsai, Weiser, Benabou and Nagata2021; Huang et al., Reference Huang, Wee, Low, Koong, Htay and Fan2021). Anxiety has a considerable negative effect on adult functioning (Adwas et al., Reference Adwas, Jbireal and Azab2019), sleep (Cox and Olatunji, Reference Cox and Olatunji2016; Deng et al., Reference Deng, Zhou, Hou, Silver, Wong and Chang2021; Chellappa and Aeschbach, Reference Chellappa and Aeschbach2022; Zhang et al., Reference Zhang, Chen, Xu, Yin, Dong and Chen2022), attention (Spalding and Nicholls, Reference Spalding and Nicholls2021; Kennedy et al., Reference Kennedy, Mohamed, Schwenn, Beaudequin, Shan, Hermens and Lagopoulos2022; Kwarteng et al., Reference Kwarteng, Wang, Micov, Hausknecht, Turk and Ishiwari2022) and social skills (Pereira-Lima and Loureiro, Reference Pereira-Lima and Loureiro2015; Moeller and Seehuus, Reference Moeller and Seehuus2019). Because the concerning levels of anxiety among adults have various detrimental consequences on one’s life and functionality, it is important to uncover some of its causal factors, in order to explore this psychopathological entity and to tend to its consequences more efficiently (Hashempour and Mehrad, Reference Hashempour and Mehrad2014; Maloney et al., Reference Maloney, Sattizahn and Beilock2014; Khan et al., Reference Khan, Khan, Khan and Khan2017; Millroth and Frey, Reference Millroth and Frey2021; Urzúa et al., Reference Urzúa, Henríquez, Caqueo-Urízar and Landabur2021; Liu et al., Reference Liu, Jin, Chen, Zhu, Xiao, Xu and Zhang2024). As anxiety translates into severe worry and negative anticipation about the future, intolerance of uncertainty could be a potential leading factor for its occurrence.
Intolerance of uncertainty and anxiety
Intolerance of uncertainty is defined as the negative “cognitive, behavioral and emotional reactions to uncertainty” (Freeston et al., Reference Freeston, Rhéaume, Letarte, Dugas and Ladouceur1994), considering that uncertainty represents a lack of information about the future (Gu et al., Reference Gu, Gu, Lei and Li2020). Individuals who have a high intolerance of uncertainty would highly apprehend potential future negative events and would consider them as a threat, disregarding their likelihood and probability (Carleton et al., Reference Carleton, Sharpe and Asmundson2007; Gu et al., Reference Gu, Gu, Lei and Li2020). Intolerance of uncertainty is founded in significant worry about uncertainty in the future and has initially appeared in studies related to anxiety (Carleton, Reference Carleton2012; Carleton et al., Reference Carleton, Mulvogue, Thibodeau, McCabe, Antony and Asmundson2012; Mahoney and McEvoy, Reference Mahoney and McEvoy2012; McEvoy and Mahoney, Reference McEvoy and Mahoney2012; Chen et al., Reference Chen, Yao and Qian2018; Gu et al., Reference Gu, Gu, Lei and Li2020; Jenkinson et al., Reference Jenkinson, Milne and Thompson2020; Li et al., Reference Li, Xia, Cheng and Li2020; Becerra et al., Reference Becerra, Gainey, Murray and Preece2023). In fact, intolerance of uncertainty has now become a key factor to distinguish individuals who suffer from generalized anxiety disorder from healthy ones, as well as other anxiety disorders, for example social anxiety (Carleton, Reference Carleton2012; Mahoney and McEvoy, Reference Mahoney and McEvoy2012; Counsell et al., Reference Counsell, Furtado, Iorio, Anand, Canzonieri and Fine2017; Chen et al., Reference Chen, Yao and Qian2018; Gu et al., Reference Gu, Gu, Lei and Li2020; Becerra et al., Reference Becerra, Gainey, Murray and Preece2023). Therefore, high intolerance of uncertainty is related to higher anxiety (Shihata et al., Reference Shihata, McEvoy and Mullan2017). An interesting example of this could be the COVID-19 pandemic, which significantly increased the levels of anxiety among the general population (Choi et al., Reference Choi, Hui and Wan2020; Hyland et al., Reference Hyland, Shevlin, McBride, Murphy, Karatzias and Bentall2020; Kan et al., Reference Kan, Raoofi, Rafiei, Khani, Hosseinifard and Tajik2021; Lakhan et al., Reference Lakhan, Agrawal and Sharma2020; Peteet, Reference Peteet2020; Daly and Robinson, Reference Daly and Robinson2022; Zhu et al., Reference Zhu, Zhang, Li, Chen and Wang2023). This could be explained by the uncertainty that this pandemic brought about, for example related to health, work, school and more, which many found intolerable (Del Valle et al., Reference Del Valle, Andrés, Urquijo, Yerro-Avincetto, López-Morales and Canet-Juric2020; Liyanage et al., Reference Liyanage, Saqib, Khan, Thobani, Tang and Chiarot2021; Taquet et al., Reference Taquet, Holmes and Harrison2021; Satici et al., Reference Satici, Saricali, Satici and Griffiths2022; Andrews et al., Reference Andrews, Li, Minihan, Songco, Fox and Ladouceur2023; Bavolar et al., Reference Bavolar, Kacmar, Hricova, Schrötter, Kovacova-Holevova, Köverova and Raczova2023; Sergi et al., Reference Sergi, Picconi, Fermani, Bongelli, Lezzi, Saggino and Tommasi2023). This thus resulted in recorded increases in different aspects of anxiety, such as death anxiety and a generally more negative affect (Sergi et al., Reference Sergi, Picconi, Fermani, Bongelli, Lezzi, Saggino and Tommasi2023).
Intolerance of uncertainty and fear of happiness
Fear of happiness (FoH) is the belief that experiencing joy may lead to negative consequences or suffering (Joshanloo, Reference Joshanloo2024). While the correlation between intolerance of uncertainty and anxiety has been established, FoH seems to mediate the relationship between these two variables. This will be justified by the correlation between FoH and each of these factors, starting with intolerance of uncertainty.
First, it is important to note that little research has been done about intolerance of uncertainty and FoH, highlighting once again the importance of this paper. However, intolerance of uncertainty has been associated with trouble experiencing any kind of positive emotion, thus providing a link to FoH – the difficulty experiencing this positive emotion (Morriss et al., Reference Morriss, Goh, Hirsch and Dodd2023; Sahib et al., Reference Sahib, Chen, Cárdenas, Calear and Wilson2024; Sriyanto and Hakim, Reference Sriyanto and Hakim2024). A study conducted by Bakioğlu et al. (Reference Bakioğlu, Korkmaz and Ercan2021) has also established a link between intolerance of uncertainty and higher anxiety, and lower positivity, which can be related to levels of FoH.
Fear of happiness and anxiety
Second, research has noted that FoH can be linked to anxiety among adults (Joshanloo, Reference Joshanloo2013; Türkmen and Sezer, Reference Türkmen and Sezer2023; Joshanloo, Reference Joshanloo2024). FoH is increasingly experienced by adults, especially those who suffer from low self-esteem or who have traits such as perfectionism or pessimism, also highlighting the role of culture and religion in this trait (Joshanloo, Reference Joshanloo2024). Moreover, this factor has been shown to often result not only in depression, as previously noted (Gilbert et al., Reference Gilbert, McEwan, Catarino, Baião and Palmeira2014; Jordan et al., Reference Jordan, Collins, Dunaway, Kilgore and Winer2021; De Vuyst et al., Reference De Vuyst, Belmans, Takano, Depreeuw, De Grave and Raes2023; Eliüşük Bülbül and Özbay, Reference Eliüşük Bülbül and Özbay2024; Elmas and Çevik, Reference Elmas and Çevik2024; Joshanloo, Reference Joshanloo2024), but also in stress, levels of antisocial behavior, panic disorder, cognitive distortions and notably anxiety (Joshanloo, Reference Joshanloo2013; Gilbert et al., Reference Gilbert, McEwan, Catarino, Baião and Palmeira2014; Muhtar, Reference Muhtar2016; Belen et al., Reference Belen, Yildirim and Belen2020; Blasco-Belled et al., Reference Blasco-Belled, Rogoza, Alsinet and Torrelles-Nadal2021; Lambert et al., Reference Lambert, Draper, Warren, Joshanloo, Chiao, Schwam and Arora2022; Elmas, Reference Elmas2022; İşgör et al., Reference Isgör, Yilmaz and Laçin2022; Türkmen and Sezer, Reference Türkmen and Sezer2023; Elmas and Çevik, Reference Elmas and Çevik2024; Gandhi, Reference Gandhi2024; Joshanloo, Reference Joshanloo2024; Srivastava, Reference Srivastava2024). Indeed, FoH impairs motivation to achieve goals, as well as the self-confidence needed to believe that one is initially capable of achieving these goals, partly explaining the correlation between FoH and increased anxiety levels (Belen et al., Reference Belen, Yildirim and Belen2020). Additionally, a study conducted by İşgör et al. (Reference Isgör, Yilmaz and Laçin2022) underlined the link between FoH and rumination patterns – frequent and prolonged negative thoughts about one’s subjective experiences, personality and emotions (Stelmach-Lask et al., Reference Stelmach-Lask, Glebov-Russinov and Henik2024). These are a main aspect of anxiety, aligning with previously mentioned research (Gilbert et al., Reference Gilbert, McEwan, Catarino, Baião and Palmeira2014; Jordan et al., Reference Jordan, Collins, Dunaway, Kilgore and Winer2021; De Vuyst et al., Reference De Vuyst, Belmans, Takano, Depreeuw, De Grave and Raes2023; Eliüşük Bülbül and Özbay, Reference Eliüşük Bülbül and Özbay2024; Gandhi, Reference Gandhi2024) and thus providing another connection between FoH and anxiety. Therefore, the literature indicates that there is a correlation between FoH and anxiety, proven by an increase in symptoms of anxiety and patterns related to it such as rumination, or lower motivation and self-esteem noted among individuals with FoH. Considering that a link has also been established in the literature between FoH and intolerance of uncertainty, while also taking into account the major role of FoH in anxiety, this study considers FoH as a mediator between these two variables.
Rationale and aim
With the aforementioned high prevalence of anxiety among adults (Remes et al., Reference Remes, Brayne, Van Der Linde and Lafortune2016; Mirzaei et al., Reference Mirzaei, Ardekani, Mirzaei and Dehghani2019; Goodwin et al., Reference Goodwin, Weinberger, Kim, Wu and Galea2020; Amu et al., Reference Amu, Osei, Kofie, Owusu, Bosoka and Konlan2021; Kan et al., Reference Kan, Raoofi, Rafiei, Khani, Hosseinifard and Tajik2021), the importance of widening the research and literature about this trait is evident. Furthermore, with intolerance of uncertainty and FoH becoming increasingly important and interesting topics in the field of psychology (Carleton et al., Reference Carleton, Sharpe and Asmundson2007; Gu et al., Reference Gu, Gu, Lei and Li2020; Morriss et al., Reference Morriss, Goh, Hirsch and Dodd2023; Joshanloo, Reference Joshanloo2024; Sahib et al., Reference Sahib, Chen, Cárdenas, Calear and Wilson2024; Sriyanto and Hakim, Reference Sriyanto and Hakim2024), the relevance of this paper is highlighted. This importance is also exacerbated by the potential application of these findings in clinical practice and interventions, especially in cognitive behavioral therapy (CBT), be it to tackle the thought patterns behind intolerance of uncertainty and the maladaptive schemas of FoH symptoms of anxiety (Bomyea et al., Reference Bomyea, Ramsawh, Ball, Taylor, Paulus, Lang and Stein2015; Talkovsky and Norton, Reference Talkovsky and Norton2016; Torbit and Laposa, Reference Torbit and Laposa2016; Keefer et al., Reference Keefer, Kreiser, Singh, Blakeley-Smith, Duncan, Johnson, Klinger, Meyer, Reaven and Vasa2017; Blasco-Belled et al., Reference Blasco-Belled, Rogoza, Alsinet and Torrelles-Nadal2021; Laposa et al., Reference Laposa, Katz, Lisi, Hawley, Quigley and Rector2022; Wilson et al., Reference Wilson, Abbott and Norton2023; Elmas and Çevik, Reference Elmas and Çevik2024; Joshanloo, Reference Joshanloo2024; Srivastava, Reference Srivastava2024; Engin et al., Reference Engin, Okur, Kütük and Satıcı2025; Yıldırım et al., Reference Yıldırım, Aksoy, Öztekin, Mohammed Abdullah Alkhulayfi, Aziz and Gómez-Salgado2025).
It is also important to note that the link between the three variables intolerance of uncertainty, FoH and anxiety has not yet been clearly researched, especially not considering FoH as a mediation factor, with no studies studying these exact variables together. Indeed, findings have established a link between intolerance of uncertainty and anxiety, as previously mentioned (Carleton, Reference Carleton2012; Mahoney and McEvoy, Reference Mahoney and McEvoy2012; McEvoy and Mahoney, Reference McEvoy and Mahoney2012; Bomyea et al., Reference Bomyea, Ramsawh, Ball, Taylor, Paulus, Lang and Stein2015; Chen et al., Reference Chen, Yao and Qian2018; Gu et al., Reference Gu, Gu, Lei and Li2020; Jenkinson et al., Reference Jenkinson, Milne and Thompson2020; Li et al., Reference Li, Xia, Cheng and Li2020; Becerra et al., Reference Becerra, Gainey, Murray and Preece2023; Kock et al., Reference Kock, Belmans and Raes2023; Joshanloo, Reference Joshanloo2024; Morriss, Reference Morriss2025), as well as between FoH and anxiety (Joshanloo, Reference Joshanloo2013; Bomyea et al., Reference Bomyea, Ramsawh, Ball, Taylor, Paulus, Lang and Stein2015; Kock et al., Reference Kock, Belmans and Raes2023; Türkmen and Sezer, Reference Türkmen and Sezer2023; Joshanloo, Reference Joshanloo2024). However, intolerance of uncertainty includes a higher sensitivity to threat (Morriss et al., Reference Morriss, Macdonald and Van Reekum2016; Tanovic et al., Reference Tanovic, Gee and Joormann2018; Milne et al., Reference Milne, Lomax and Freeston2019), which can reinforce the FoH schema that perceives happiness and its consequences as a threat (De Vuyst et al., Reference De Vuyst, Belmans, Takano, Depreeuw, De Grave and Raes2023; Elmas and Çevik, Reference Elmas and Çevik2024; Joshanloo, Reference Joshanloo2024). This higher sensitivity to threat is also correlated with increased levels of anxiety, which is often represented as irrational worry about potential threats (O’donovan et al., Reference O’donovan, Slavich, Epel and Neylan2013; Nelson et al., Reference Nelson, Hodges, Hajcak and Shankman2015; Bardeen and Daniel, Reference Bardeen and Daniel2018; Burani and Nelson, Reference Burani and Nelson2020). Moreover, a higher sensitivity to threat or vigilance can also be linked to avoidance or repression of emotions (Bardeen et al., Reference Bardeen, Tull, Stevens and Gratz2015; Li et al., Reference Li, Xia, Cheng and Li2020; Joshanloo, Reference Joshanloo2024), which FoH – the avoidance of the emotion of happiness – is an example of (Elmas and Çevik, Reference Elmas and Çevik2024; Joshanloo, Reference Joshanloo2024; Srivastava, Reference Srivastava2024; Lee et al., Reference Lee, Wan and Yang2025). Higher vigilance and avoidance/repression of emotions are also linked to rumination (Garrison et al., Reference Garrison, Kahn, Miller and Sauer2014; Brookes et al., Reference Brookes, Sharpe and Dear2017; Eisma et al., Reference Eisma, de Lang and Boelen2020; Stelmach-Lask et al., Reference Stelmach-Lask, Glebov-Russinov and Henik2024). Additionally, the latter is a pattern observed in FoH, as previously shown (İşgör et al., Reference Isgör, Yilmaz and Laçin2022; Stelmach-Lask et al., Reference Stelmach-Lask, Glebov-Russinov and Henik2024) as well as a symptom of anxiety. Therefore, this suggests that, through the examples of higher sensitivity to threat, avoidance of emotions and rumination, FoH could be considered as a link between intolerance of uncertainty and anxiety. Finally, a study conducted by Körün and Satıcı (Reference Körün and Satıcı2025) examines the mediating role of FoH between intolerance of uncertainty and rumination. However, rumination has been established as a symptom of anxiety, which thus underlines the aim of this study of broadening these results to anxiety in general, by studying the mediating role of FoH between intolerance of uncertainty and anxiety.
Given that FoH may vary across individuals depending on sociodemographic characteristics, such as sex or alcohol use, these variables will be accounted for in the present study. Indeed, research suggests that high levels of FoH are more often recorded among women than among men, which can be related to greater emotional sensitivity and socialization around emotional restraint (Joshanloo, Reference Joshanloo2013). In some cultures, women may internalize beliefs that expressing happiness invites negative consequences such as envy or emotional vulnerability (Carbone et al., Reference Carbone, Loewenstein, Scopelliti and Vosgerau2024). These gender differences appear to be shaped by cultural context and individual coping styles, though findings are not entirely consistent across studies. Furthermore, research suggests that FoH may lead some individuals to use alcohol to cope with uncomfortable emotions or avoid positive feelings (Sayette, Reference Sayette2017). However, this relationship is not yet well understood and requires further study.
Furthermore, the significance of studying these variables among Lebanese adults lies in the relevance that all of intolerance of uncertainty, FoH and anxiety have in this population. Indeed, in the past few years, Lebanon has survived an enormous number of crises, from the COVID-19 pandemic to the financial collapse, to the 2020 Beirut Blast, to the recent war (El Othman et al., Reference El Othman, Touma, El Othman, Haddad, Hallit, Obeid, Salameh and Hallit2021; Hashim et al., Reference Hashim, Uakkas, Reda, Ramadhan and Mostafa2022; World Bank, 2024; Altaweel, Reference Altaweel, Sakai and Suzuki2025). This has undeniably impacted their mental health, even going into what Farran (Reference Farran2021) labels as “a mental health epidemic”, one of the main mental disorders being anxiety (El-Khoury et al., Reference El-Khoury, Haidar and Charara2020; Haddad et al., Reference Haddad, Darwich, Obeid, Sacre, Zakhour and Kazour2020; Hallit et al., Reference Hallit, Obeid, Haddad, Hallit, Akel and Haddad2020; Kmeid et al., Reference Kmeid, Nacouzi, Hallit and Rohayem2020; Merhy et al., Reference Merhy, Azzi, Salameh, Obeid and Hallit2021). Moreover, it is important to note that FoH is culturally wired in the Middle Eastern and Lebanese mentality and values, and this has increased after the recent events (Halawi and Salloukh, Reference Halawi and Salloukh2020). However, the matter is still widely understudied and is currently arising in the research field (El Khoury et al., Reference El Khoury, Malaeb, Sakr, Dabbous, Fekih-Romdhane, Hallit and Obeid2024). A sample of Lebanese adults was chosen due to the relevance of the research topic within the Lebanese cultural and socioeconomic context. Lebanon’s unique social dynamics, exposure to ongoing stressors and evolving mental health awareness make it a valuable population for examining the link between FoH, intolerance of uncertainty and anxiety. Moreover, a scarcity of empirical data from this population in the existing literature was noted, highlighting the need for localized research to inform culturally appropriate interventions and theoretical models. For these reasons, this study aimed at assessing the mediating role of FoH between intolerance of uncertainty and levels of anxiety among a sample of Lebanese adults.
Methods
Study design and participants
This study employed a correlational design based on cross-sectional data collection. It collected data from 905 participants in Lebanon between August and September 2024, with eligibility requirements including being a resident or citizen of Lebanon, with a minimum age of 18 years. The mean age of participants was 29.90 years, with a standard deviation of 9.28, and 60% of them identified as female.
Data collection was done using a survey created on Google Forms, which was shared on social media. The research team employed snowball sampling to recruit participants. This technique began with sending the survey link to a few individuals, who were encouraged to share it within their network, facilitating a broader reach. Given Lebanon’s context of instability and ongoing crises, traditional recruitment methods may not have been viable, so snowball sampling was used to build trust and overcome potential reluctance to participate.
The survey was anonymous, with participants providing digital informed consent to be able to access the questionnaire. Participation was voluntary and without compensation, and the completion of the survey needed about 20 minutes.
The same methods were used as other studies that also tackled intolerance of uncertainty in Lebanon (Assaf et al., Reference Assaf, Malaeb, Sakr, Dabbous, Fekih-Romdhane, Hallit and Obeid2025; Obeid et al., Reference Obeid, Bitar, Malaeb, Sakr, Dabbous, Hallit and Fekih-Romdhane2025) to ensure the validity of the results and the conformity of the procedure.
Minimal sample size calculation
To detect the mediated effect, a sample size of 411 individuals is needed, calculated using the formula suggested by Fritz and MacKinnon (Reference Fritz and MacKinnon2007). The formula is given as
$ n=\frac{L}{f^2}+k+1 $
, where
$ n $
is the minimal sample size. In this context,
$ L $
is set to 7.85, which applies for a one-predictor ordinary least squares regression with a type I error rate (α) of 0.05 and a power of 0.80. The value of
$ f, $
representing a small effect size, is 0.14. The value of
$ k $
is 9, which denotes the number of predictors in the regression equation.
Questionnaire
The questionnaire was presented in Arabic, Lebanon’s official language, to ensure accessibility for participants. It started with an introductory section outlining the study’s purpose and included an online consent checkpoint where participants confirmed their voluntary participation. The consent process assured participants of the confidentiality and anonymity of their responses.
The survey collected various sociodemographic data, such as age, sex, marital status and Household Crowding Index (HCI), which serves as a measure of socioeconomic status (SES). The HCI was calculated by dividing the number of people in the household by the number of rooms in the house (excluding the kitchen and bathrooms). These variables are inversely proportional; thus, a lower HCI suggests a higher SES, as it means less overcrowding at home (Melki et al., Reference Melki, Beydoun, Khogali, Tamim and Yunis2004). Participants’ smoking habits, alcohol use, cannabis consumption and other psychological conditions were also noted, as well as four other self-report scales explained below.
The Intolerance of Uncertainty Scale (IUS-12) (Carleton et al., Reference Carleton, Sharpe and Asmundson2007). The shortened version of the IUS-27, validated in Arabic (Chaaya et al., Reference Chaaya, Hallit, Postigo, Malaeb, Sakr and Dabbous2024), includes 12 items scored on a Likert scale from 1 (not at all characteristic of me) to 5 (very characteristic of me). This scale measures the extent to which the participant is distressed by uncertainty. It has two subscales: prospective anxiety evaluates the need for predictability and the tendency to actively seek it to reduce the risk of uncertainty, and inhibitory anxiety scores the participants’ avoidance of uncertainty and the behavioral inhibition when faced with it. Prospective anxiety is scored by adding the answers of the subscales’ items; the higher the score, the greater the intolerance of uncertainty. In this study, Cronbach’s α was 0.90 for both subscales.
Generalized Anxiety Scale-5 (GAD-5). Validated in Arabic (Sawma et al., Reference Sawma, El Nour, Malaeb, Sakr, Dabbous, El-Khatib and Obeid2024), the GAD-5 is a self-report instrument that consists of five items, each rated on a four-point Likert scale from 0 (not at all) to 3 (nearly every day) (Goldberg et al., Reference Goldberg, Bridges, Duncan-Jones and Grayson1988). The total score is computed by adding the answers of the items, with higher scores indicating higher anxiety (Cronbach’s α in this study = 0.90).
The Fear of Happiness Scale (FHS) (Joshanloo, Reference Joshanloo2013). Validated in Arabic (El Khoury et al., Reference El Khoury, Malaeb, Sakr, Dabbous, Fekih-Romdhane, Hallit and Obeid2024), the FHS is a short questionnaire that includes five items, which are intended to score for FoH, i.e., the belief that the participant does not deserve happiness or that the latter will bring about negative consequences. The items are scored on a Likert scale from 1 to 7, from strongly disagree to strongly agree. The total score is computed by adding the answers of the statements, with higher scores indicating higher FoH.
Statistical analysis
The SPSS v.27 software was used for the statistical analysis. The anxiety score was considered normally distributed since the skewness and kurtosis values were between the −1 and +1 interval. The Student t-test was used to compare the mean value of a continuous variable across two levels of a dichotomous variable and the Pearson’s test to correlate two continuous variables. In the context of this study, effect size refers to a quantitative measure of the strength or magnitude of a relationship or difference between variables, independent of the sample size. A value of 0.2 reflects a weak effect, whereas values of 0.5 and 0.8 indicate a moderate and large effect size, respectively (Sullivan and Feinn, Reference Sullivan and Feinn2012).
The mediation analysis was performed using PROCESS MACRO (a SPSS add-on) v3.4 Model 4, with the number of bootstrap samples set at 5000 and a 95% confidence interval. Four pathways resulted from this analysis: pathway A of the independent variable to the mediator, pathway B of the mediator to the dependent variable and pathways C and C’ indicating the total and direct effects of the independent variable to the dependent variable. We considered the mediation analysis to be significant if the confidence interval did not pass by zero. Covariates entered in the model were those that showed a p < 0.25 in the bivariate analysis. P < 0.05 was considered statistically significant.
Patient and public involvement
As this study was conducted among the non-clinical general population, there was no direct involvement of patients, service users or caregivers in the design, conduct, analysis or interpretation of the data. However, the study aimed to gather insights from a broad cross-section of the public to better understand general trends and behaviors. While the research did not include active participation from specific patient or public groups, the findings may indirectly benefit from the diverse perspectives of the general population included in the study.
Results
Participants
In total, 905 participants participated in this study, with a mean age of 27.38 years and 60% being female. Other descriptive statistics of the sample are presented in Table 1.

Analysis of mediation
The mediation analysis taking anxiety as the dependent variable was adjusted over the following covariates: sex, smoking, alcohol and psychological problems. FoH partially mediated the association between prospective (indirect effect: Beta = 0.17; Boot SE = 0.03; Boot CI 0.10; 0.24) and inhibitory (indirect effect: Beta = 0.23; Boot SE = 0.05; Boot CI 0.14; 0.32) anxiety and anxiety; higher prospective/inhibitory anxiety was significantly associated with higher FoH and directly associated with higher anxiety. Finally, FoH was significantly and directly associated with higher anxiety (Figures 1 and 2).

Discussion
Intolerance of uncertainty and fear of happiness
To start with, both prospective and inhibitory anxiety, which are facets of intolerance of uncertainty, are significantly correlated with FoH. This could be explained by the fact that for some, especially in the Lebanese population, living and accepting happiness may be unfamiliar, as individuals’ life satisfaction would be low (Joshanloo, Reference Joshanloo2013; Abdel-Khalek, Reference Abdel-Khalek2015; Yildirim, Reference Yildirim2019). Indeed, the levels of unhappiness and depression among the Lebanese are high (Ahmadieh et al., Reference Ahmadieh, Itani, Itani, Sidani, Kassem, Farhat, Jbeily and Itani2018; Harper Shehadeh et al., Reference Harper Shehadeh, Abi Ramia, Cuijpers, El Chammay, Heim and Kheir2020; Obeid et al., Reference Obeid, Lahoud, Haddad, Sacre, Akel and Fares2020; Cuijpers et al., Reference Cuijpers, Heim, Abi Ramia, Burchert, Carswell and Cornelisz2022). Therefore, the prospective experience of happiness may thus be worrisome for some, as they do not really know what to expect, increasing their uncertainty about it, leading to a fear of this emotion. Thus, if some people struggle with anticipating new experiences and do not tolerate this much, they may fear happiness, as this emotion may be unfamiliar to them.
Moreover, this correlation between intolerance of uncertainty and FoH can also be demonstrated by the hopelessness that some individuals may experience, which is also common in Lebanon given the many hardships this population has been through (Obeid et al., Reference Obeid, Haddad, Zakhour, Fares, Akel, Salameh and Hallit2019; Chahine et al., Reference Chahine, Salameh, Haddad, Sacre, Soufia and Akel2020; Sharanek, Reference Sharanek2020; Obeid et al., Reference Obeid, Haddad, Fares, Malaeb, Sacre and Akel2021; Zakhour et al., Reference Zakhour, Haddad, Sacre, Fares, Akel and Obeid2021). In fact, as one experiences apprehension of the future and its uncertainty, hopelessness about it and the inability to cope with it may arise (Demirtas and Yildiz, Reference Demirtas and Yildiz2019; Özdemir et al., Reference Özdemir, Özden Hergül, Öztürk and Arslan2021; Engin et al., Reference Engin, Güler and Yaşar2024; Erkan and Kavak Budak, Reference Erkan and Kavak Budak2024). Consequently, this hopelessness may also reinforce the person’s FoH as they do not believe that they deserve to or even can experience this emotion in the future anymore, thus losing hope about it and even becoming scared and worried about it (Bloore et al., Reference Bloore, Jose and Joshanloo2020; Koca, Reference Koca2020; Dobos et al., Reference Dobos, Mellor and Piko2024). Therefore, intolerance of uncertainty reduced feelings of hope among individuals, who thus have a more negative perspective on their future, leading to an increased FoH.
Fear of happiness and anxiety
Additionally, FoH is also linked to higher levels of anxiety. To start with, an explanation for this could be the reduced self-efficacy that one may experience when they fear happiness and believe that they do not deserve it (Erozkan et al., Reference Erozkan, Dogan and Adiguzel2016; Marzi and Saadati Shamir, Reference Marzi and Saadati Shamir2019; Mete, Reference Mete2021; Türkmen and Sezer, Reference Türkmen and Sezer2023; Gandhi, Reference Gandhi2024). In terms, this could increase their anxiety (Bandura, Reference Bandura, Schwarzer and Wicklund1991; Razavi et al., Reference Razavi, Shahrabi and Siamian2017; Ng and Lovibond, Reference Ng and Lovibond2020; Burns et al., Reference Burns, Martin, Kennett, Pearson and Munro-Smith2021; Simonetti et al., Reference Simonetti, Durante, Ambrosca, Arcadi, Graziano and Pucciarelli2021; Lau et al., Reference Lau, Bhattacharjya, Fong, Nicol, Lenze and Baum2022; Wan et al., Reference Wan, Lin, Li, Tu and Qin2024) as they are not achieving their potential and fulfilling their purpose. Examples of this can be at work (Lestari et al., Reference Lestari, Watini and Rose2024), in their relationships (Weiser and Weigel, Reference Weiser and Weigel2016), hobbies (Bum et al., Reference Bum, Lee and Choi2021; Neroni et al., Reference Neroni, Meijs, Kirschner, Xu and de Groot2022), etc., which all stem from the deep fear of being happy and thus may induce anxiety (Regan et al., Reference Regan, Lambert, Kelly, McElduff, Girgis, Kayser and Turner2014; Li et al., Reference Li, Dai, Wu, Jia, Gao and Fu2019; Deady et al., Reference Deady, Collins, Johnston, Glozier, Calvo, Christensen and Harvey2022; Li et al., Reference Li, Lai, Friedrich, Liu and Popkin2023). Therefore, FoH creates a circle of self-sabotage in the individual, whose self-efficacy decreases on many levels, in turn increasing their anxiety. This also aligns with the previously stated fact that FoH transforms one’s perspective and beliefs about themselves (Stelmach-Lask et al., Reference Stelmach-Lask, Glebov-Russinov and Henik2024), morphing them into negative beliefs about oneself, leading them to this cycle of self-sabotage that induces anxiety.
Furthermore, the effect of FoH on anxiety may also be explained by the maladaptive belief patterns that one develops about others and the world, which were previously explained and which may have several significant effects on anxiety (Blasco-Belled et al., Reference Blasco-Belled, Rogoza, Alsinet and Torrelles-Nadal2021; Elmas and Çevik, Reference Elmas and Çevik2024; Joshanloo, Reference Joshanloo2024). Indeed, on the one hand, these negative beliefs about others may bring about insecurities in the individual, who may for example start feeling judged by others, unwanted or even unloved, making them withdraw from their social life (Savitsky et al., Reference Savitsky, Epley and Gilovich2001; Ciarrochi, Reference Ciarrochi2004; Leary et al., Reference Leary, Tate, Adams, Batts Allen and Hancock2007; Frías et al., Reference Frías, Shaver and Díaz-Loving2014; Skeen, Reference Skeen2014; Valshtein et al., Reference Valshtein, Mutter, Oettingen and Gollwitzer2020; van Prooijen, Reference van Prooijen2023; Jørgensen and Bøye, Reference Jørgensen and Bøye2024), or feeling paranoid because they think others want to harm them, thus becoming excessively weary about other people. On the other hand, negative beliefs about the world could also bring them to withdraw to protect themselves from all the bad that they believe exists outside, as one may start believing that the world is cruel, unfair and filled with sadness (Cann et al., Reference Cann, Calhoun, Tedeschi, Kilmer, Gil-Rivas, Vishnevsky and Danhauer2010; Clifton et al., Reference Clifton, Baker, Park, Yaden, Clifton and Terni2019; Wood et al., Reference Wood, Coplan, Hipson and Bowker2022). For example, an individual who fears happiness and has developed the maladaptive belief that the world is not worth trying will isolate themselves, start spending too much time at home or may quit college, which may create financial, parental or social problems that can increase their anxiety (Clifton and Kerry, Reference Clifton and Kerry2023). Consequently, the negative beliefs about the world and others that stem from FoH increase anxiety, as the individual becomes dysregulated and their lifestyle is negatively affected in several aspects (Buschmann et al., Reference Buschmann, Horn, Blankenship, Garcia and Bohan2018; Sherwood et al., Reference Sherwood, Carydias, Whelan and Emerson2020; Hickman et al., Reference Hickman, Marks, Pihkala, Clayton, Lewandowski and Mayall2021; Leibovitz et al., Reference Leibovitz, Shamblaw, Rumas and Best2021; Vasileva et al., Reference Vasileva, Alisic and De Young2021; Vazquez et al., Reference Vazquez, Valiente, García, Contreras, Peinado, Trucharte and Bentall2021; Galway and Field, Reference Galway and Field2023). In addition to that, in their most severe forms, these negative and maladaptive thoughts and emotions might amplify and become more severe, sometimes to the point of developing into severe mental disorders, such as depression, generalized anxiety disorder or social anxiety disorder, eating disorders, borderline personality disorder, or even obsessive-compulsive disorder or posttraumatic stress disorder (Borton et al., Reference Borton, Markowitz and Dieterich2005; Vocks et al., Reference Vocks, Wächter, Wucherer and Kosfelder2008; Taylor and Stopa, Reference Taylor and Stopa2013; Koerner et al., Reference Koerner, Tallon and Kusec2015; Eagleson et al., Reference Eagleson, Hayes, Mathews, Perman and Hirsch2016; Buschmann et al., Reference Buschmann, Horn, Blankenship, Garcia and Bohan2018; Masland et al., Reference Masland, Schnell and Shah2020; Hodny et al., Reference Hodny, Prasko, Ociskova, Vanek, Holubova, Sollar and Nesnidal2021; Siregar et al., Reference Siregar, Rahmadiyah and Siregar2021; Kube, Reference Kube2023; Palmieri et al., Reference Palmieri, Sassaroli, Ruggiero, Caselli, Spada and Mansueto2023; Kube and Rauch, Reference Kube and Rauch2025). Therefore, FoH may also create negative beliefs about the world and others, which may lead to anxiety through social withdrawal, paranoia, deterioration of lifestyle and more, thus producing higher anxiety in the concerned individuals.
Mediation analysis
In sum, FoH represents a mediator between intolerance of uncertainty and anxiety, as its link with the two variables has been shown in the previous sections, showing that FoH significantly increases the levels of anxiety, also considering intricate relationship with levels of intolerance of uncertainty. Indeed, the latter may bring about FoH since the latter may be an unfamiliar emotion to some (Joshanloo, Reference Joshanloo2013; Abdel-Khalek, Reference Abdel-Khalek2015; Yildirim, Reference Yildirim2019). FoH may also emphasize a feeling of hopelessness among some subjects (Demirtas and Yildiz, Reference Demirtas and Yildiz2019; Bloore et al., Reference Bloore, Jose and Joshanloo2020; Koca, Reference Koca2020; Özdemir et al., Reference Özdemir, Özden Hergül, Öztürk and Arslan2021; Dobos et al., Reference Dobos, Mellor and Piko2024; Engin et al., Reference Engin, Güler and Yaşar2024; Erkan and Kavak Budak, Reference Erkan and Kavak Budak2024). Consequently, FoH increases levels of anxiety since it may reduce one’s feeling of self-efficacy (Regan et al., Reference Regan, Lambert, Kelly, McElduff, Girgis, Kayser and Turner2014; Bandura, Reference Bandura, Schwarzer and Wicklund1991; Erozkan et al., Reference Erozkan, Dogan and Adiguzel2016; Razavi et al., Reference Razavi, Shahrabi and Siamian2017; Li et al., Reference Li, Dai, Wu, Jia, Gao and Fu2019; Marzi and Saadati Shamir, Reference Marzi and Saadati Shamir2019; Ng and Lovibond, Reference Ng and Lovibond2020; Burns et al., Reference Burns, Martin, Kennett, Pearson and Munro-Smith2021; Mete, Reference Mete2021; Simonetti et al., Reference Simonetti, Durante, Ambrosca, Arcadi, Graziano and Pucciarelli2021; Deady et al., Reference Deady, Collins, Johnston, Glozier, Calvo, Christensen and Harvey2022; Lau et al., Reference Lau, Bhattacharjya, Fong, Nicol, Lenze and Baum2022; Li et al., Reference Li, Lai, Friedrich, Liu and Popkin2023; Türkmen and Sezer, Reference Türkmen and Sezer2023; Gandhi, Reference Gandhi2024; Wan et al., Reference Wan, Lin, Li, Tu and Qin2024). This may stem from their negative beliefs about themselves, which may thus deteriorate their lifestyle and increase their levels of anxiety. FoH may also develop negative and maladaptive beliefs of others and the world (Blasco-Belled et al., Reference Blasco-Belled, Rogoza, Alsinet and Torrelles-Nadal2021; Elmas and Çevik, Reference Elmas and Çevik2024; Joshanloo, Reference Joshanloo2024) and may be very dangerous for their lifestyle (Buschmann et al., Reference Buschmann, Horn, Blankenship, Garcia and Bohan2018; Sherwood et al., Reference Sherwood, Carydias, Whelan and Emerson2020; Hickman et al., Reference Hickman, Marks, Pihkala, Clayton, Lewandowski and Mayall2021; Leibovitz et al., Reference Leibovitz, Shamblaw, Rumas and Best2021; Vasileva et al., Reference Vasileva, Alisic and De Young2021; Vazquez et al., Reference Vazquez, Valiente, García, Contreras, Peinado, Trucharte and Bentall2021; Clifton and Kerry, Reference Clifton and Kerry2023; Galway and Field, Reference Galway and Field2023), their social life (Savitsky et al., Reference Savitsky, Epley and Gilovich2001; Ciarrochi, Reference Ciarrochi2004; Leary et al., Reference Leary, Tate, Adams, Batts Allen and Hancock2007; Cann et al., Reference Cann, Calhoun, Tedeschi, Kilmer, Gil-Rivas, Vishnevsky and Danhauer2010; Frías et al., Reference Frías, Shaver and Díaz-Loving2014; Skeen, Reference Skeen2014; Clifton et al., Reference Clifton, Baker, Park, Yaden, Clifton and Terni2019; Valshtein et al., Reference Valshtein, Mutter, Oettingen and Gollwitzer2020; Wood et al., Reference Wood, Coplan, Hipson and Bowker2022; van Prooijen, Reference van Prooijen2023; Jørgensen and Bøye, Reference Jørgensen and Bøye2024) and their mental health (Borton et al., Reference Borton, Markowitz and Dieterich2005; Vocks et al., Reference Vocks, Wächter, Wucherer and Kosfelder2008; Taylor and Stopa, Reference Taylor and Stopa2013; Koerner et al., Reference Koerner, Tallon and Kusec2015; Eagleson et al., Reference Eagleson, Hayes, Mathews, Perman and Hirsch2016; Buschmann et al., Reference Buschmann, Horn, Blankenship, Garcia and Bohan2018; Masland et al., Reference Masland, Schnell and Shah2020; Hodny et al., Reference Hodny, Prasko, Ociskova, Vanek, Holubova, Sollar and Nesnidal2021; Siregar et al., Reference Siregar, Rahmadiyah and Siregar2021; Kube, Reference Kube2023; Palmieri et al., Reference Palmieri, Sassaroli, Ruggiero, Caselli, Spada and Mansueto2023; Kube and Rauch, Reference Kube and Rauch2025), which also includes elevated levels of anxiety (Buschmann et al., Reference Buschmann, Horn, Blankenship, Garcia and Bohan2018; Sherwood et al., Reference Sherwood, Carydias, Whelan and Emerson2020; Hickman et al., Reference Hickman, Marks, Pihkala, Clayton, Lewandowski and Mayall2021; Leibovitz et al., Reference Leibovitz, Shamblaw, Rumas and Best2021; Vasileva et al., Reference Vasileva, Alisic and De Young2021; Vazquez et al., Reference Vazquez, Valiente, García, Contreras, Peinado, Trucharte and Bentall2021; Clifton and Kerry, Reference Clifton and Kerry2023; Galway and Field, Reference Galway and Field2023).
Therefore, FoH is considered a mediator because of the one-way relationship proposed with anxiety, as no effect of anxiety on FoH has been recorded (Belen et al., Reference Belen, Yildirim and Belen2020; İşgör et al., Reference Isgör, Yilmaz and Laçin2022; Türkmen and Sezer, Reference Türkmen and Sezer2023; Elmas and Çevik, Reference Elmas and Çevik2024; Joshanloo, Reference Joshanloo2024; Srivastava, Reference Srivastava2024; Teke, Reference Teke2025). Furthermore, while the cognitive triad – negative and maladaptive beliefs about oneself, others and the world – has been proven to have an influence on depression and depressive symptoms, the main link that has been made to anxiety is that the latter acts as a result of these thoughts and beliefs, often because of depression (Kaslow et al., Reference Kaslow, Stark, Printz, Livingston and Ling Tsai1992; Braet et al., Reference Braet, Wante, Van Beveren and Theuwis2015; Berghuis et al., Reference Berghuis, Pössel and Pittard2020). In fact, this resulting anxiety often presents as rumination, which has been established as a result of maladaptive schemas and negative beliefs about oneself, others and the world (Orue et al., Reference Orue, Calvete and Padilla2014; Balsamo et al., Reference Balsamo, Carlucci, Sergi, Klein Murdock and Saggino2015; Carlucci et al., Reference Carlucci, D’Ambrosio, Innamorati, Saggino and Balsamo2018; Bazargani et al., Reference Bazargani, Moraveji and Asadi2023; Eshghifar et al., Reference Eshghifar, Mohammadkhani and Hasani2025). This also aligns with the studies that show that maladaptive belief patterns may lead to more severe cases of generalized and social anxiety disorders (Taylor and Stopa, Reference Taylor and Stopa2013; Koerner et al., Reference Koerner, Tallon and Kusec2015; Buschmann et al., Reference Buschmann, Horn, Blankenship, Garcia and Bohan2018). Therefore, a one-way causality between FoH and anxiety can be implied, proving the role of the latter as a mediator between intolerance of uncertainty and anxiety.
Clinical implications
As a result of these inferences, it is clear that intolerance of uncertainty, through its mediator, FoH, contributes to elevated levels of anxiety among Lebanese adults. Therefore, these negative anxiety symptoms could be dealt with and relieved through the implementation of CBT. It would be advantageous for individuals to cope with this high anxiety in an efficient, time-saving, evidence-based way (DiMauro et al., Reference DiMauro, Domingues, Fernandez and Tolin2013; Loerinc et al., Reference Loerinc, Meuret, Twohig, Rosenfield, Bluett and Craske2015; Kishita and Laidlaw, Reference Kishita and Laidlaw2017; McMorris et al., Reference McMorris, Turner, Johnston, Clark, Howe, McConnell and McFee2024). Indeed, patients would learn to target their negative beliefs that induce their inability to cope with this anxiety, as well as to practice exercises that reduce the symptoms that they would be suffering from (Flynn and Warren, Reference Flynn and Warren2014; Robichaud and Dugas, Reference Robichaud and Dugas2015). Negative and maladaptive beliefs related to intolerance of uncertainty and FoH can also be tackled through CBT (Talkovsky and Norton, Reference Talkovsky and Norton2016; Keefer et al., Reference Keefer, Kreiser, Singh, Blakeley-Smith, Duncan, Johnson, Klinger, Meyer, Reaven and Vasa2017; Blasco-Belled et al., Reference Blasco-Belled, Rogoza, Alsinet and Torrelles-Nadal2021; Wilson et al., Reference Wilson, Abbott and Norton2023; Elmas and Çevik, Reference Elmas and Çevik2024; Srivastava, Reference Srivastava2024). Additionally, an anxiety prevention program that has been created based on CBT named “Journey of the Brave” could also be implemented, allowing the participants to target their anxiety symptoms and their aforementioned factors (Ohashi et al., Reference Ohashi, Urao, Fujiwara, Koshiba, Ishikawa and Shimizu2024). This program is comprised of group therapy sessions that allow improvement of social skills, interpersonal connection and discovery and more, making the participants more open and willing to adapt and implement cognitive and behavioral changes (Ohashi et al., Reference Ohashi, Urao, Fujiwara, Koshiba, Ishikawa and Shimizu2024). Therefore, these allow the person to tackle different aspects of their mental health, one of them being their anxiety, which is why this program has been reported to reduce anxiety symptoms (Ohashi et al., Reference Ohashi, Urao, Fujiwara, Koshiba, Ishikawa and Shimizu2024). Finally, patient education could be a major intervention that would help in the alleviation or at least understanding of the concerned population in their thought patterns, emotions and symptoms, thus allowing them to improve based on this understanding (Huang et al., Reference Huang, Wee, Low, Koong, Htay and Fan2021).
Limitations
It is important to start by mentioning that the literature available about the subject was little, especially regarding FoH, which might have jeopardized the discussion about mediation. Indeed, no article targeted this subject directly – considering the three variables together, whether in Lebanon or not – which resulted in little literature to rely on to discuss the mediation and compare the present results to. Therefore, this surely was a significant limitation to the findings of the paper. Furthermore, the data were collected through self-reported questionnaires, making the results at risk of a social desirability bias, if participants gave socially acceptable responses, for example considering their potential FoH. Participants might also have lacked self-awareness, thus reducing the accuracy of results such as anxiety. Thus, this might have affected the accuracy of the data collected and thus of the results, for example about the levels of anxiety. Moreover, the data were collected, and the survey was sent using the snowballing sampling technique, thus reducing the inclusivity of the sample and the reach of different populations and groups. Indeed, since random sampling was not applied due to circumstantial constraints, the generalizability of the results to the general Lebanese adult population may be questionable. Thus, the sample may not represent this population as a whole and may be biased depending on the participants it reached and who completely filled the survey. Additionally, the interpretation of the association between intolerance of uncertainty and FoH should be approached cautiously. In the original discussion, this link was partly interpreted in light of the mean level of FoH in the sample; however, the average score of a variable cannot be used as evidence for causal or explanatory mechanisms underlying its association with another variable. Therefore, the relationship between these constructs should be considered explanatory, with further research needed to clarify the directionality and underlying processes. It is also important to note that a longitudinal study might have been more valid and reliable to test the mediation hypothesis, which would have provided a higher accuracy of results over time, as well as of the causal effect.
Conclusion
This study showed that FoH mediates the relationship between the two other variables, as FoH may be correlated with intolerance of uncertainty – represented by prospective and inhibitory anxiety – in the sense that happiness may represent a new and unfamiliar emotion to the Lebanese and through the hopelessness that this population may suffer from. Additionally, FoH acts as a mediator between these two variables by being significantly correlated with levels of anxiety, reducing the self-efficacy, productivity and achievement of the individual, while concurrently reinforcing their negative and maladaptive beliefs about themselves, others and the world. Therefore, CBT may represent a beneficial asset and intervention for these individuals. Programs to implement this approach or to educate the population may also be put into effect, benefiting different groups and populations of Lebanese. Ultimately, it would be interesting to mention the effect of low self-efficacy, hopelessness and negative beliefs in depression among Lebanese individuals and thus to tackle the role of intolerance of uncertainty and of FoH in regard to this emotion.

Comments
Dear Editor,
The authors and I have submitted to your highly esteemed journal an article entitled: Mediating effect of fear of happiness between intolerance of uncertainty and anxiety among Lebanese adults.
Fear of Happiness represent the negative feelings that emerge as one apprehends or experiences the positive emotion of happiness. This experience is intrinsically related to both intolerance of uncertainty, the apprehension of the unknown, and to symptoms of anxiety. While all of these factors are common among the Lebanese population, especially given the hardships it has been through for the past few years, no research has yet studied the three of them in Lebanon. Therefore, this paper tackles the role of fear of happiness as a mediator between intolerance of uncertainty and anxiety among Lebanese adults. The present study is a cross-sectional investigation that recruited 905 Lebanese adults, of which 60% were women, and where the mean age was 29.90 years old. The data was collected through a survey in Arabic, that included the Intolerance of Uncertainty Scale (IUS-12), the Generalized Anxiety Scale-5 (GAD-5), and the Fear of Happiness Scale (FHS) in their validated Arabic versions. The results of the present study proved that fear of happiness does have a mediating role between intolerance of uncertainty and anxiety levels among Lebanese adults. Interventions such as Cognitive Behavioral Therapy and educational programs that tackle these factors may be beneficial to these individuals to relieve symptoms of anxiety and to tackle other negative thought patterns.
Please find attached our manuscript for consideration and potential review for publication; we hope to publish our findings in your highly esteemed journal since we consider each result a key issue to be addressed and investigated at the national and regional levels.
