Despite the increased knowledge about the prevalence and consequences of eating disorders (ED), they continue to be underdiagnosed and undertreated. Being more common in women of childbearing age, the perinatal period may play a decisive role in the incidence and course of these pathologies. The Screen for Disordered Eating (SDE) was developed for the screen of ED in primary care.

Our aim was to analyze the psychometric properties of the Portuguese Version of SDE in women during the perinatal period.

Participants were 346 women with a mean age of 31.68 of years old (± 4.061; range: 18-42). 160 were pregnant (second or third trimester) and 186 were in the post-partum (mean baby´s age=4.37 months (± 2.87; range: 1-12). They answered an online survey including the Portuguese version of the SDE and of the Eating Disorder Examination – Questionnaire (EDE-Q-7).

Confirmatory Factor Analysis showed that the unidimensional model presented good fit indexes in pregnancy (), post-partum () and considering both – perinatal period (χ2/df=2.0335; RMSEA=.0547, p<.001; CFI=0.9976 TLI=0.9939, GFI=0.9906). The Cronbach’s alfa were ≥ 0.65. All the items contributed to the internal consistency and presented high internal validity. Pearson correlations between SDE and EDE-Q-7 total scores were significant (p<.001) positive and high in pregnancy (.639), postpartum (.583) and the perinatal period (.617).

The Portuguese version of SDE has shown good validity (construct and concurrent) and internal consistency. As such, SDE might be a useful tool to screen ED in women during the perinatal period.

The Eating Disorder Examination Questionnaire short version (EDE-Q7) presented better psychometric properties than the Fairburn’s 28-items original version, not only in girls (Machado et al. 2018), but also in older women (Pereira et al. 2021; Pereira et al. 2022). It comprises 7 items in three subscales: Dietary Restraint/DR; Shape and Weight Overvaluation/SWO and Body Dissatisfaction/BD. In a more recent clinical study in men (Laskowski et al. 2023) the factors associated with body concerns and dissatisfaction weren’t fully represented in the questionnaire, possibly indicating differences in body ideals, specially relating to musculature.

We aimed to analyze the psychometric properties of the Portuguese version of EDE-Q7 in males.

Participants were 227 male individuals with a mean age of 30.41 years (±13.96; range: 14-73 years). They answered an online survey including the Portuguese versions of the Screen for Disordered Eating/SDE; the Body Image Concern Inventory/BICI and the Muscle Dysmorphia subscale of the Eating Disorder Assessment for Men/DM-EDAM.

Confirmatory Factor Analysis showed that the second order model presented good fit (χ2/df=2.437; RMSEA=.0794; CFI=.986 TLI=.974, GFI=.967). Cronbach’s alpha was .856 for the total, .876 for DR and .917 for SWO and .900 for BD. All items contributed to internal consistency and presented high internal validity. Pearson’s correlations of EDE-Q7 with BICI (.465), DM-EDAM (.384) and SDE (.361) were significant (p<.001) and moderate.

Also in men, the Portuguese version of EDE-Q7 demonstrates good validity (construct and convergent) and reliability.

The EDE-Q-7 Portuguese version presented good reliability and validity in Portuguese women fro the general population (Pereira et al. 2022).

The aim of our study was to analyse the psychometric properties of the EDE-Q-7 in a sample of Portuguese women during the perinatal period.

Participants were 346 women with a mean age of 31.68 of years old (± 4.061; range: 18-42). 160 were pregnant (second or third trimester) and 186 were in the post-partum (mean baby´s age=4.37 months (± 2.87; range: 1-12). They answered an online survey including the Portuguese version of the EDE-Q-7 and of the Screen for Disordered Eating/SDE.

Confirmatory factor analysis (CFA) presented adequate fit, in pregnancy (χ2/df=; RMSEA=, p<.001; CFI=; TLI=; GFI=), postpartum (χ2/df=; RMSEA=, p<.001; CFI=; TLI=; GFI=) and considering both – perinatal period (χ2/df=2.7998; RMSEA=.0722, p<.001; CFI=.9709; TLI=.9444; GFI=.9761). The Cronbach’s alpha coefficients were >0.90 for the total and approximately .70 for the three factors - Dietary restraint, Shape/weight overvaluation and Body dissatisfaction. All the items contributed to the internal consistency and presented high internal consistency. Pearson correlations between factors and total scores were significant, positive and high, as well as between the EDE-Q-7 measures and SDE (>.60 with the total; >.40 with the factors), in pregnancy, postpartum and considering both periods.

Presented sound psychometric properties across the perinatal period, the EDE-Q-7 and can be very useful to evaluate the presence and severity of eating disorders symptoms in women in pregnancy and post-partum.

Although symptom presentation varies by gender, almost all eating disorder/ED instruments have been developed and validated on females. The Eating Disorder Assessment for Men (EDAM; Stanford & Lemberg 2012) is a male specific self-report measure, composed of four sub-scales, proved to be useful to assess gender differences in ED presentations (Nagata et al. 2021). The MD comprises 5 items about the overwhelming concern with muscularity and the false perception of having an underdeveloped body.

Having already valid measures of body image and eating behaviors in men, we now aim to analyze the psychometric properties of the Portuguese version of MD, in order to have a quick and rigorous measure of this specific construct.

Participants were 227 male individuals (mean age=30.41 years±13.96; range: 14-73 years). They answered an online survey including the preliminary DM and the Portuguese validated versions of the Eating Disorder Examination Questionnaire (EDE-Q7) and the Body Image Concern Inventory (BICI).

Confirmatory Factor Analysis showed that the unidimensional model presented good fit indexes (χ2/df=.6829; RMSEA=.0000; CFI=1.00 TLI=1.01, GFI=.995). Cronbach’s alfa was .891; all the items contributed to the internal consistency and had high internal validity. Pearson correlations of DM with EDE-Q7 and BICI were significant (p<.001) and moderate-high, respectively,.384 and .522.

The Portuguese preliminary version of DM-EDAM demonstrated validity (construct and convergent) and reliability. can be used for clinical and research purposes, namely in an ongoing project we have in progress, about body image, disordered eating, gender and age.

Epilepsy is one of the most common serious brain illness, with symptoms influenced by multiple risk factors and a strong genetic predisposition, rather than having a single expression and cause¹. Neuropsychiatric symptoms in epilepsy can encompass manifestations such as mood alterations, anxiety, sleep disturbances, psychosis, and behavioral disorders. While the motor and sensory manifestations of epileptic seizures are widely recognized, neuropsychiatric symptoms accompanying epilepsy are often underestimated. Therefore, it is essential to understand the most prevalent epidemiological profile of these patients to improve the diagnosis and management of these symptoms.

Our goal was to evaluate the neuropsychiatric behavior of epilepsy patients in Brazilian over the past 3 years through hospitalization data in order to outline an epidemiological and behavioral profile.

A cross-sectional, descriptive, retrospective, and quantitative study was conducted on hospitalizations of individuals simultaneously diagnosed with epilepsy, schizotypal and delusional disorders, and mood disorders in all five regions of Brazil (South, Southeast, Midwest, North, and Northeast) between February 2020 and December 2022. Data from January 2020 were not available. The data used were collected through the Department of Health Informatics of the Brazilian Unified Health System (DATASUS) in the “Hospital Information System of SUS” section, gathering information regarding the nature of care, age range, gender, and ethnicity of the patients.

The analysis covers the years 2020 to 2022, totaling 503,045 hospitalizations. In 2022, the highest number of cases occurred (≈ 37.55%), followed by 2021 (≈ 33.62%) and 2020 (≈ 28.81%). Urgent hospitalizations represented ≈ 90.85% of the total. The most affected age group was 30 to 39 years old (≈ 18.30%). Men were more affected than women (≈ 52.03% and ≈ 47.96%, respectively), and Caucasians accounted for ≈ 36.07% of the hospitalizations. The average length of stay was 19.1 days, and the mortality rate was 1.4%.

Thus, there is a gradual and annual increase in the number of hospitalizations during the observed period. While there is a minimal disparity between the affected genders, it is evident that the profile of male, caucasian, and adult patients is the most prevalent. Moreover, the predominantly urgent nature of hospitalizations points to an alarming scenario regarding this issue. From the analysis of the data obtained in the study, there is a clear need for interventions capable of reducing the prevalence of hospitalizations for neuropsychiatric symptoms in epilepsy patients in Brazil.

Neuropsychiatric disorders are the leading cause of disability worldwide, as seen in cases such as depression, anxiety, bipolar mood disorder and schizophrenia, which can be developed or exacerbated by the use of psychoactive substances. Most mental disorders have an early onset, often leading to early and/or permanent disability, increasing the need and cost of healthcare. Therefore, it is necessary to improve the identification of the epidemiological profile of these cases in the South of Brazil in order to enhance the diagnosis and reduce the costs associated with managing these disorders.

The present study aimed to analyze statistical data regarding hospitalizations related to mental disorders caused by the use of psychoactive substances and alcohol in the southern region of Brazil, highlighting the pathological scenario and identifying the most prevalent profiles of these disorders in this region.

A cross-sectional, descriptive, retrospective, and quantitative study was conducted on hospitalizations of individuals diagnosed with mental and behavioral disorders due to the use of psychoactive substances and alcohol in the states of the Southern region of Brazil (Paraná, Santa Catarina, and Rio Grande do Sul) between February 2020 and December 2022. Data of January 2020 were not available. The data used were collected through the Department of Health Informatics of the Brazilian Unified Health System (DATASUS) in the “Hospital Information System of SUS” section, gathering information regarding the nature of the care, age range, gender, and ethnicity of the patients.

The study covers the years 2020 to 2022, indicating a total of 81,608 hospitalizations, with the year 2022 having the highest number of cases (≈ 37.13%), followed by 2021 (≈ 33.30%) and 2020 (≈ 29.55%). The states with the highest number of hospitalizations were Rio Grande do Sul (≈ 54.90%), Paraná (≈ 29.29%), and Santa Catarina (≈ 15.79%). Urgent hospitalizations accounted for ≈ 87.29% of the total. The most affected age group was 30 to 39 years old (≈ 25.61%). Men were more affected than women (≈ 81.70% and ≈ 18.28%, respectively). Caucasians accounted for ≈ 64.29% of the hospitalizations. The average length of stay was 20.8 days, and the mortality rate was 0.32%.

There is a clear increase in the number of hospitalizations related to mental disorders caused by the use of psychoactive substances in the period from 2020 to 2022 in the southern region of Brazil, with the highest number of cases in the state of Rio Grande do Sul. The most affected population consisted of Caucasian men aged 30 to 39 years old. Furthermore, these results may be related to the increasing trend of psychoactive substance use among the Brazilian population and also the COVID-19 pandemic, which led to a period of underreporting due to social isolation.

Mental health-related stigma occurs not only within the public community but is also an issue among healthcare professionals. The relationship between national culture and provider stigma remains yet to be empirically attested.

We performed a cross-sectional multicentre study across 32 European countries to investigate the attitudes of psychiatrists towards patients with mental health problems. We aimed to examine the relationship of attitude with country-specific indicators.

We measured stigmatizing attitudes using the Opening Minds Stigma Scale for Health Care Providers (OMS-HC) within an online survey among specialists and trainees in general adult, child and adolescent psychiatry. Its total score was correlated with the Human Development Index (HDI), the Democracy Index (DI), the Social Progress Index (SPI), the number of psychiatrists per 100,000 people, and the Hofstede dimensions. Latent class analysis was done to find subgroups of countries according to the stigmatizing attitudes of psychiatrists and the six Hofstede dimensions.

Altogether, n=4245 participants completed the survey. The total score of the OMS-HC significantly correlated with the long-term orientation (r=0.453, p=0.015) and indulgence dimensions (r=-0.629, p<0.0001) and with the HDI (r=-0.503, p=0.005), DI (r=-0.418, p=0.024), SPI (r=-0.348, p=0.040). The latent class analysis separated high- and low-stigma countries. High stigma was associated with high power distance and uncertainty scores.

Findings from this study not only expand knowledge of factors related to stigmatizing attitudes of healthcare professionals, but also enlighten the cultural aspects of the stigma that could contribute to the further development of anti-stigma programs.

In recent years, mental health has gained prominence in public health, prompting thorough investigations into psychiatric condition trends. This study conducts a comprehensive epidemiological analysis of hospitalizations for Schizophrenia, Schizotypal, and Delirium Disorders in Rio Grande do Sul (RS) over the past five years. By revealing these patterns, it enhances our understanding of regional mental health dynamics and offers insights for intervention strategies, resource planning, and improved mental healthcare. The ultimate goal is to advance more effective and accessible mental healthcare in RS and beyond.

This study aims to analyze the prevalence and epidemiological profile of hospitalizations due to psychiatric disorders to assist in the diagnosis and outcome of affected patients.

A cross-sectional, descriptive, retrospective, and quantitative study was conducted regarding hospitalizations for Schizophrenia, Schizotypal Disorders, and Delirium in the state of RS between January 2018 and November 2022. Data were collected from the Department of Informatics of the Brazilian Unified Health System (DATASUS) in the “Hospital Information System of SUS” section, focusing on the nature of care, age group, gender, and ethnicity of the patients. The information was aggregated over the five-year period based on the four mentioned descriptors and subsequently analyzed to establish a profile of hospitalizations during that period.

The analysis spans from 2018 to 2022, encompassing a total of 28,345 hospitalizations. In 2019, there was the highest number of cases (22.21%), followed by 2018 (21.08%). Urgent care admissions constituted 85.34% of the total. The age group most affected was 35 to 39 years (11.8%). Men were more affected than women (60.18%), and the majority of hospitalizations were among the Caucasian ethnicity (75.12%). The average length of stay was 23.7 days, and the mortality rate stood at 0.26%.

The increasing trend in hospitalizations, peaking in 2019, highlights the need for preventive measures. Urgent admissions (85.34%) underscore the demand for accessible mental health resources. Men in the 35 to 39 age group are disproportionately affected, suggesting specific risk factors. The predominance of Caucasian ethnicity emphasizes the need for culturally sensitive care. A longer average length of stay (23.7 days) underscores treatment complexity, while a low mortality rate (0.26%) signals effective medical care. In essence, these findings inform tailored mental health policies to enhance service quality and prioritize patient-centered approaches.

The Screen for Disordered Eating/SDE was created as a primary care screening method for eating disorders, including binge eating disorder (Maguen et al. 2018). The SDE comprises five items (yes/no answers), extracted from other validated self-reported questionnaires assessing eating psychopathology. Its validity and reliability has proved in a Portuguese psychometric study, that only included woman (Pereira et al. 2022). It psychometric properties have yet to be evaluated in men.

We aim to assess the psychometric properties of the Portuguese version of SDE in males.

Participants were 227 male individuals with a mean age of 30.41 years (±13.96; range: 14-73). They answered an online survey including the Portuguese preliminary versions of the seven-item Eating Disorder Examination Questionnaire/EDE-Q7; the Body Image Concern Inventory/BICI and the Muscle Dysmorphia subscale of the Eating Disorder Assessment for Men/DM-EDAM.

Confirmatory Factor Analysis showed good fit for the unidimensional model (χ2/df=1.483; RMSEA=.0460; CFI=.980 TLI=.961, GFI=.988). Cronbach’s alpha was .621 which although inferior to .7 can be explained by the small number of items and the fact that each one assesses different dimensions. All items contributed to the internal consistency and presented high internal validity. Pearson’s correlations of SDE with BICI (.317) and EDE-Q7 (.361) were significant and moderate. The correlation with DM-EDAM was non-significant, probably due to its focus on muscle dysmorphia, which is not included in SDE’s items.

The Portuguese version of SDE demonstrated adequate validity (construct and convergent) and reliability.

The Profile of Mood States is one of the most widely used instruments to assess mood states. It is a rapid and economic method of assessing transient affective states (McNair et al. 2003) and it has been translated and validated to several languages including Portuguese. In our country we have several versions, with different factorial structures and number of items. The scale presents a list of feelings and emotions (adjectives) that people commonly experience.

With university students, we have used a version composed of 36 items that evaluates three factors, with good validity and reliability: Depression, Anxiety/Hostility and Positive Affect (Amaral et al. 2013).

However, to be included in digital apps that in addition to ecological momentary assessment parameters require a weekly or even daily assessment of mood states, this version has little usability.

To develop a shorter version of the POMS-36 based on Exploratory Factor Analysis and to analyse its construct validity using Confirmatory Factor Analysis in a sample of Portuguese college students.

765 students (69.2% females; mean age=22.09±2.433; range: 17-26) fill in the POMS-36 and the Perceived Stress Scale (Amaral et al. 2014). The total sample was randomly divided in two sub-samples. Sample A (N=380) was used to EFA and sample B (N=385) was used to CFA.

Through EFA (with varimax rotation and extracting three factors), the four items with the highest loadings in their respective factor were selected. Then, the CFA, carried out with the AMOS, revealed that this three-factor model, with two pairs of correlated errors, indicated a good fit (X2/df= 4.6010; CFI =.9561; GFI =.9406; TLI=.9559; RMSEA=.0687, p[rmsea=0.04]. The internal consistency analysis resulted in α (Cronbach alphas) <.75 for the three factors. Pearson correlations of the three factors - Depression, Anxiety/Hostility, Amability/Vigour – with Perceived stress were all significantly (p<.01) and moderate, respectively: .533, .614 and -.461.

Although much shorter, the new POMS-12 has good validity (construct and divergent-convergent) and reliability, being more suitable in studies that require frequent and rapid self-monitoring of affective states, such as ISABELA (“IoT Student Advisor and Best Lifestyle Analyser”), an app targeting student mental health and well-being in which we have been working.

Besides the traditionally studied group of young females, disordered eating occurs in all age groups (Eedena, Hoekena, and Hoek 2021). In recent years, there has been an increase in the prevalence of eating disorders and symptoms in middle-aged and older women (40 years old and over) (Mangweth-Matzek and Hoek 2017).

Experts in eating psychopathology in special groups such as Samuels, Maine and Taltillo (2019) suggest the use of the Screen for Disordered Eating (SDE; Magen et al. 2018) in the psychometric assessment of women in middle age and older. The SDE was developed to allow the Eating Disorders (ED) screening in Primary Health Care in people of all ages and without excluding Binge Eating Disorder (BED).

The SDE is composed of five items (yes or no answers), extracted from other validated self-reported questionnaires for the assessment of eating psychopathology.

To analyze the psychometric properties of the Portuguese Version of the Screen for Disordered Eating in a sample of women from the general population aged 40 and over.

Participants were 516 women with a mean age of 50.28 of years old (± 8.063; range: 40-80). They answered an online survey including the preliminary Portuguese version of the SDE and the Portuguese version of the Eating Disorder Examination – Questionnaire (EDE-Q-7; Pereira et al. 2021).

Confirmatory Factor Analysis showed that the unidimensional model presented good fit indexes (χ2/df=1.502; RMSEA=.0311, p<.001; CFI=.987 TLI=.995, GFI=.965). The Cronbach’s alfa was .762. All the items contributed to the internal consistency, as they presented item-total correlations above .40 and the exclusion of each one would decrease the alpha. Pearson correlations between SDE and the EDE-Q-7 were significant (p<.01), positive and moderate/high, as follows: .516 with the total score and .318, .503 and .536 respectively with the dimensional scores of Dietary restraint, Shape/weight overvaluation and Body dissatisfaction.

As observed with the original English-language scale, the Portuguese version of the SDE has shown good validity (construct and concurrent) and internal consistency. As such, the SDE might be a useful tool to investigate disordered eating psychopathology in older women. In the near future we will determine the SDE cut-offs with the best combination of sensitivity and specificity to screen for eating disorders in this populational group.

The relationship between narcissism and burnout has been explored in the literature with somewhat inconsistent findings. Though most studies have found a positive correlation between Narcissism and Burnout, some have failed to establish a significant link between the two, while others have even reported a protective role of narcissism against burnout.

In our previous work regarding the link between perfectionism and student burnout, we found that when using the Big Three model of Perfectionism, Narcissistic Perfectionism had only a weak connection to burnout, requiring full mediation by low-self compassion.

We hypothesized that this might be due to an exaggerated sense of Academic Efficacy in Narcissistic Perfectionists, which would compensate for some of the emotional exhaustion and depersonalization brought upon by their efforts to gain the admiration of others.

To investigate the link between Narcissistic Perfectionism and Academic Efficacy, and its impact on burnout levels.

A sample of 1080 students from healthcare-related courses (80,7% females; mean age=21.13±3.023; range: 17-41) filled in an online questionnaire including, among others, the Portuguese Version of BIG3-SF and MBI-SS. Correlational analysis was performed.

Contrary to our initial theory, Narcissistic Perfectionism did not significantly correlate with Academic Efficacy (r=0.011, p=0.728), although it had significant correlations with the other burnout dimensions and total burnout score.

This work disproved our initial hypothesis, suggesting that narcissistic perfectionism may be associated with other nefarious dimensions that cancel out the effects of grandiosity and inflated self-esteem on the perception of academic efficacy. This negative finding could possibly be further explored by using a psychometric instrument that differentiates between maladaptive and adaptive facets of narcissism.

The Portuguese version of the Big Three Perfectionism Scale (BTPS), a 45-item self-report measure of rigid, self-critical, and narcissistic perfectionism, presented good reliability, construct and concurrent validity both in a sample of university students (Lino, Pereira et al. 2018) and of adults from the general population (Oliveira, Pereira et al. 2021).

To develop and validate a Portuguese brief version of the BTPS, the Big Three Perfectionism Scale–Short Form (BTPS-SF) in a sample of university students.

The procedure followed to select items for the short version was based on the 45-items BTPS confirmatory factorial analysis (Lino, Pereira et al. 2018). Following Feher et al. (2020) strategy, with Canadian university students, we retained between one and two from each of the 10 perfectionism facets in the BTPS, 16 items in total. The 16 items selected had loadings ranging from .63 to .88 (Lino, Pereira et al. 2018), thus meeting the suggested requirement of high loadings being above .60 in magnitude (Afifi et al. 2011).

Participants were 633 Portuguese students (medicine, dentistry and health technologies; 82.1% girls; mean age=21.25±3.115); they answered an online survey including the BTPS and the Depression Anxiety and Stress Scale (DASS; Xavier et al. 2017).

Confirmatory Factor Analysis showed that both the first (χ2/df=3.074; RMSEA=.0573, p<.001; CFI=.9591; TLI=.9478, GFI=.9465) and the second order (χ2/df=3.714; RMSEA=.0655, p<.001; CFI=.9482; TLI=.9317, GFI=.9318) models presented good fit indexes. The Cronbach’s alfas were: a=.865 for the total and .855, .829 and .750, respectively for F1 (rigid perfectionism), F2 (self-critical perfectionism) and F3 (narcissistic perfectionism). Pearson coefficient correlations with DASS total score were significant (p<.01), positive and moderate for the total 16-items- BTPS (r=.375), F1 (r=.285), F2 (r=.465) and low for F3 (r=.177). Correlation coefficients with Depression, Anxiety and Stress sub-scales presented the same pattern and magnitude.

Due to its good validity and reliability, the Portuguese BTPS–SF is an efficient and useful alternative to the 55-item version. When it is not necessary to measure the ten facets, the BTPS-SF has the advantages of conciseness, brevity and ease of filling.

Electroconvulsive therapy (ECT) is an effective and safe medical procedure that mainly indicated for depression, but is also indicated for patients with other conditions. However, ECT is among the most stigmatized and controversial treatments in medicine. Our objective was to examine social media contents on Twitter related to ECT to identify and evaluate public views on the matter.

We collected Twitter posts in English and Spanish mentioning ECT between January 1, 2019 and October 31, 2020. Identified tweets were subject to a mixed method quantitative–qualitative content and sentiment analysis combining manual and semi-supervised natural language processing machine-learning analyses. Such analyses identified the distribution of tweets, their public interest (retweets and likes per tweet), and sentiment for the observed different categories of Twitter users and contents.

“Healthcare providers” users produced more tweets (25%) than “people with lived experience” and their “relatives” (including family members and close friends or acquaintances) (10% combined), and were the main publishers of “medical” content (mostly related to ECT’s main indications). However, more than half of the total tweets had “joke or trivializing” contents, and such had a higher like and retweet ratio. Among those tweets manifesting personal opinions on ECT, around 75% of them had a negative sentiment.

Mixed method analysis of social media contents on Twitter offers a novel perspective to examine public opinion on ECT, and our results show attitudes more negative than those reflected in studies using surveys and other traditional methods.
