Recent changes to US research funding are having far-reaching consequences that imperil the integrity of science and the provision of care to vulnerable populations. Resisting these changes, the BJPsych Portfolio reaffirms its commitment to publishing mental science and advancing psychiatric knowledge that improves the mental health of one and all.
Electroconvulsive therapy (ECT) is effective in treating severe major depressive disorder, manic episodes, and catatonia. Despite this, it is a controversial treatment amongst patients, carers, and even some psychiatrists in the UK.
Objectives
To determine the experiences and perceptions of UK psychiatric trainees and early-career psychiatrists regarding the use of ECT in clinical practice.
Methods
An anonymous survey was distributed online to UK psychiatric trainees and early-career psychiatrists across the country. The questionnaire consisted of 36 multiple-choice and Likert scale questions.
Results
So far, 44 trainees and early-career psychiatrists have responded. The vast majority had witnessed ECT administration during training and had administered ECT under supervision. Most respondents agreed or strongly agreed that ECT was a safe and effective treatment, and most respondents disagreed or strongly disagreed that ECT is cruel or outdated. There were more varied views regarding perceptions of side effects and contraindications: a minority of respondents were unsure about whether ECT had long-term side effects, and whilst most respondents disagreed or strongly disagreed that ECT has many risks and contraindications, just under half were unsure or agreed.
Conclusions
Most UK psychiatric trainees and early-career psychiatrists have experience of ECT during training and believe ECT is a safe and effective treatment. Respondents had a mixed view regarding the side-effect profile and risks/contraindications of ECT, which may be an important area for further education and training.
Polygenic risk scores for educational attainment (PRSEA), cognitive reserve (CR), and clinical symptoms are associated with functioning in first-episode psychosis (FEP). Nevertheless, the mechanisms underlying their complex interaction are yet to be explored. This study assessed the mediating role of CR and clinical symptoms, both negative (NS) and positive (PS), on the interrelationship between PRSEA and functionality, one year after a FEP.
Methods
A total of 162 FEP patients underwent clinical, functional, and genetic assessments. Using genome-wide association study summary results, PRSEA were constructed for each individual. Two mediation models were performed. The parallel mediation model explored the relationship of PRSEA with functionality through CR and clinical symptoms. The serial mediation model tested a causal chain of the three mediators: CR, NS, and PS. Mediation analysis was performed using the PROCESS function V.4.1 in SPSS V.22.
Results
A serial mediation model revealed a causal chain for PRSEA > CR > NS > Functionality (β = −0.35, 95%CI [−0.85, −0.04], p < 0.05). The model fit the data satisfactorily (CFI = 1.00; RMSEA = 0.00; SRMR = 7.2 × 10−7). Conversely, no parallel mediation was found between the three mediators, PRSEA and functionality and the model poorly fit the data (CFI = 0.30; RMSEA = 0.25; SRMR = 0.11).
Conclusions
Both CR and NS mediate the relationship between PRSEA and functionality at one-year follow-up, using serial mediation analysis. This may be relevant for prevention and personalized early intervention to reduce illness impact and improve functional outcomes in FEP patients.
The association between adverse childhood experiences (ACEs) and adult depression and anxiety has been well described (Aafjes-van Doorn et al., 2020; Dolbier et al., 2021; Herzog & Schmahl, 2018). However, cognitive flexibility, as a potential moderating factor of this relationship, has been underreported (Kalia et al., 2021). We hypothesize that increased ACEs will be associated with increased symptoms of depression and anxiety, and cognitive flexibility will exhert a moderating role in this relationship.
Participants and Methods:
Participants from the Evelyn F. McKnight University of Miami Frailty Registry were included in the study. 224 adults (Mage= 66.30, SD = 11.63; 59.4% female; 62.1% Hispanic/Latinx) without primary neurological disorders were recruited from University of Miami clinics and community centers. Participants completed a demographic questionnaire and neuropsychological evaluation including the Adverse Childhood Experiences inventory, Beck Depression Inventory, Beck Anxiety Inventory, and the Wisconsin Card Sorting Test (WCST). Current data were initially analyzed using descriptive statistics and correlations among variables. A series of hierarchical multiple linear regressions (HLR) were conducted to examine the effect that age has on cognitive flexibility (measured by number of perseverative errors on the WCST), as well as the association between number of ACEs endorsed on symptoms of depression and anxiety in late life.
Results:
Correlation analyses revealed a negative correlation between total ACE score and cognitive flexibility (r=-.16, p=0.03); a positive correlation between age and cognitive flexibility (r=0.19, p=0.01); and positive relationships between ACE score and both BDI (r=0.35, p<0.001) and BAI (r=0.28, p<0.001) scores. Correlations further revealed a negative correlation between cognitive flexibility and both BDI (r=-0.18, p=0.014) and BAI (r=-0.14, p=0.048) scores. A series of hierarchical multiple linear regressions revealed that total number of ACEs had a statistically significant effect on both depression (f=7.24, p<.001, ΔR2=0.072) and anxiety (f=4.57, p<.001, ΔR2=0.044) symptoms, in models adjusted for demographic correlates (i.e., age, sex, race, ethnicity). While the overall moderation model examining the effect of cognitive flexibility on the relationship between ACEs and psychopathology was significant (f=6.04, p<.001, ΔR2=0.191), the interaction was not significant (p=.4199). However, HLRs further revealed a statistically significant effect of age on cognitive flexibility (f=6.77, p=0.01, ΔR2=0.034).
Conclusions:
Current findings support past research showing higher number of ACEs are associated with more symptoms of depression and anxiety in later life. However, cognitive flexibility did not moderate the relationship between ACEs and symptoms of depression and anxiery. This suggests cognitive flexibility might not play a significant role in the association between childhood trauma and symptoms of depression and anxiety in later life. Alternatively present results could be attributed to a small sample size, or the specific measure of cognitive flexibility used. This study expands on prior research highlighting the role of cognitive flexibility on age, with age serving as a prominent feature in the association between ACEs and adult depression and anxiety. Further research examining the role of cognitive flexibility in younger and middle years and its association with ACEs and psychopathology may provide unique insights on how to intervene earlier in the life course before cognitive flexibility begins to decline.
Technological advances, such as radio-telemetry, have been increasingly employed for animal monitoring because they can furnish important information regarding the ecology and behaviour of various species. However, during a study on semi-domiciled domestic cats (Felis silvestris catus)conducted in an environmental protection area in Ilha Comprida, state of São Paulo, Brazil, we identified a case of dermatitis that was caused by a radio-collar, which was first noticed by the pet owner. This provided the opportunity for close observation not normally possible when these are used to track animals in the wild. It is our aim to bring the possibility that skin inflammation may develop when using radio-collars in radio-telemetry monitoring to the attention of other researchers. This finding highlights the need for greater attention to be paid to the use of this methodology, especially in the realm of wild animals.
Gestational diabetes mellitus (GDM) is the most common medical complication of pregnancy and a severe threat to pregnant people and offspring health. The molecular origins of GDM, and in particular the placental responses, are not fully known. The present study aimed to perform a comprehensive characterisation of the lipid species in placentas from pregnancies complicated with GDM using high-resolution MS lipidomics, with a particular focus on sphingolipids and acylcarnitines in a semi-targeted approach. The results indicated that despite no major disruption in lipid metabolism, placentas from GDM pregnancies showed significant alterations in sphingolipids, mostly lower abundance of total ceramides. Additionally, very long-chain ceramides and sphingomyelins with twenty-four carbons were lower, and glucosylceramides with sixteen carbons were higher in placentas from GDM pregnancies. Semi-targeted lipidomics revealed the strong impact of GDM on the placental acylcarnitine profile, particularly lower contents of medium and long-chain fatty-acyl carnitine species. The lower contents of sphingolipids may affect the secretory function of the placenta, and lower contents of long-chain fatty acylcarnitines is suggestive of mitochondrial dysfunction. These alterations in placental lipid metabolism may have consequences for fetal growth and development.
The European Psychiatric Association (EPA) Summer School allows psychiatric trainees and early career psychiatrists (ECPs) from all over Europe to meet, network, and learn together. After the 2020 edition being cancelled due to COVID-19, the 10th edition in 2021 focused for the first time on research and was conducted remotely.
Objectives
To provide an overview and feedback about the first Virtual EPA Research Summer School as a new way to encourage international networking during COVID-19.
Methods
The School was organized by the EPA Secretary for Education, and 4 Faculty members. It started with a “breaking the ice session” one week before and then a two-days meeting on 23-24 September 2021 using an online video-platform. This was preceded by all the 21 participants (from 18 different countries) recording a short 4-minute video presentation, which was uploaded and shared with other participants and Faculty.
Results
Participants were divided on a voluntary basis into three working groups: 1) “Drug repurposing: overcoming challenges in pharmacoepidemiology” 2) “Psychopathological research in psychiatry”; 3) “How to conduct a cross-sectional survey?”. The Summer School program was composed of plenary sessions with lectures by the Faculty members, discussion sessions, and working groups time. At the end, each group presented a summary of the work done to the rest of the participants.
Conclusions
Although the remote format limits social interactions during the Summer School, overall participants’ high satisfaction and productivity indicate that not only online formats, but also the topic of research might be covered in future editions.
Clinical intervention in early stages of psychotic disorders is crucial for the prevention of severe symptomatology trajectories and poor outcomes. Genetic variability is studied as a promising modulator of prognosis, thus novel approaches considering the polygenic nature of these complex phenotypes are required to unravel the mechanisms underlying the early progression of the disorder.
Methods
The sample comprised of 233 first-episode psychosis (FEP) subjects with clinical and cognitive data assessed periodically for a 2-year period and 150 matched controls. Polygenic risk scores (PRSs) for schizophrenia, bipolar disorder, depression, education attainment and cognitive performance were used to assess the genetic risk of FEP and to characterize their association with premorbid, baseline and progression of clinical and cognitive status.
Results
Schizophrenia, bipolar disorder and cognitive performance PRSs were associated with an increased risk of FEP [false discovery rate (FDR) ⩽ 0.027]. In FEP patients, increased cognitive PRSs were found for FEP patients with more cognitive reserve (FDR ⩽ 0.037). PRSs reflecting a genetic liability for improved cognition were associated with a better course of symptoms, functionality and working memory (FDR ⩽ 0.039). Moreover, the PRS of depression was associated with a worse trajectory of the executive function and the general cognitive status (FDR ⩽ 0.001).
Conclusions
Our study provides novel evidence of the polygenic bases of psychosis and its clinical manifestation in its first stage. The consistent effect of cognitive PRSs on the early clinical progression suggests that the mechanisms underlying the psychotic episode and its severity could be partially independent.
Longitudinal data on the mental health impact of the coronavirus disease 2019 (Covid-19) pandemic in healthcare workers is limited. We estimated prevalence, incidence and persistence of probable mental disorders in a cohort of Spanish healthcare workers (Covid-19 waves 1 and 2) -and identified associated risk factors.
Methods
8996 healthcare workers evaluated on 5 May–7 September 2020 (baseline) were invited to a second web-based survey (October–December 2020). Major depressive disorder (PHQ-8 ≥ 10), generalised anxiety disorder (GAD-7 ≥ 10), panic attacks, post-traumatic stress disorder (PCL-5 ≥ 7), and alcohol use disorder (CAGE-AID ≥ 2) were assessed. Distal (pre-pandemic) and proximal (pandemic) risk factors were included. We estimated the incidence of probable mental disorders (among those without disorders at baseline) and persistence (among those with disorders at baseline). Logistic regression of individual-level [odds ratios (OR)] and population-level (population attributable risk proportions) associations were estimated, adjusting by all distal risk factors, health care centre and time of baseline interview.
Results
4809 healthcare workers participated at four months follow-up (cooperation rate = 65.7%; mean = 120 days s.d. = 22 days from baseline assessment). Follow-up prevalence of any disorder was 41.5%, (v. 45.4% at baseline, p < 0.001); incidence, 19.7% (s.e. = 1.6) and persistence, 67.7% (s.e. = 2.3). Proximal factors showing significant bivariate-adjusted associations with incidence included: work-related factors [prioritising Covid-19 patients (OR = 1.62)], stress factors [personal health-related stress (OR = 1.61)], interpersonal stress (OR = 1.53) and financial factors [significant income loss (OR = 1.37)]. Risk factors associated with persistence were largely similar.
Conclusions
Our study indicates that the prevalence of probable mental disorders among Spanish healthcare workers during the second wave of the Covid-19 pandemic was similarly high to that after the first wave. This was in good part due to the persistence of mental disorders detected at the baseline, but with a relevant incidence of about 1 in 5 of HCWs without mental disorders during the first wave of the Covid-19 pandemic. Health-related factors, work-related factors and interpersonal stress are important risks of persistence of mental disorders and of incidence of mental disorders. Adequately addressing these factors might have prevented a considerable amount of mental health impact of the pandemic among this vulnerable population. Addressing health-related stress, work-related factors and interpersonal stress might reduce the prevalence of these disorders substantially. Study registration number: NCT04556565
Reproducibility of a deep-learning fully convolutional neural network is evaluated by training several times the same network on identical conditions (database, hyperparameters, and hardware) with nondeterministic graphics processing unit operations. The network is trained to model three typical time–space-evolving physical systems in two dimensions: heat, Burgers’, and wave equations. The behavior of the networks is evaluated on both recursive and nonrecursive tasks. Significant changes in models’ properties (weights and feature fields) are observed. When tested on various benchmarks, these models systematically return estimations with a high level of deviation, especially for the recurrent analysis which strongly amplifies variability due to the nondeterminism. Trainings performed with double floating-point precision provide slightly better estimations and a significant reduction of the variability of both the network parameters and its testing error range.
Parents who receive a diagnosis of a severe, life-threatening CHD for their foetus or neonate face a complex and stressful decision between termination, palliative care, or surgery. Understanding how parents make this initial treatment decision is critical for developing interventions to improve counselling for these families.
Methods:
We conducted focus groups in four academic medical centres across the United States of America with a purposive sample of parents who chose termination, palliative care, or surgery for their foetus or neonate diagnosed with severe CHD.
Results:
Ten focus groups were conducted with 56 parents (Mage = 34 years; 80% female; 89% White). Results were constructed around three domains: decision-making approaches; values and beliefs; and decision-making challenges. Parents discussed varying approaches to making the decision, ranging from relying on their “gut feeling” to desiring statistics and probabilities. Religious and spiritual beliefs often guided the decision to not terminate the pregnancy. Quality of life was an important consideration, including how each option would impact the child (e.g., pain or discomfort, cognitive and physical abilities) and their family (e.g., care for other children, marriage, and career). Parents reported inconsistent communication of options by clinicians and challenges related to time constraints for making a decision and difficulty in processing information when distressed.
Conclusion:
This study offers important insights that can be used to design interventions to improve decision support and family-centred care in clinical practice.
This study evaluated the effect of roughage:concentrate (R:C) ratio associated with a variable particle size of physically effective neutral detergent fibre (peNDF8) in the forage (Tifton-85 hay) on the performance, carcass traits and meat quality of lambs. Seventy-two 4-month-old, non-castrated Santa Ines male lambs (23.5 ± 2.32 kg BW) were distributed in a completely randomized design, in a 2 × 2 factorial arrangement [two peNDF8 hay particle sizes (13 and 6 mm) and two R:C ratios (700:300 and 500:500 g/kg DM total)]. DMI, DM, NFC and TDN digestibility's, N-intake and N-faecal excretion were affected by the R:C ratio (P < 0.05). However, the N-retained was not affected by the studied variables (P > 0.05). It was observed an interaction (P < 0.05) between the peNDF8 and R:C ratios for final BW, average daily gain (ADG), colour parameters and pH 24 h. The lower roughage ratio provided greater (P < 0.05) concentrations of C14:1, C16:1–cis9, C18:1–cis9, ΣMUFA, Σn–6:Σn–3 and hypocholesterolemic/hypercholesterolemic index, enzymatic activity Δ9desaturase-C16 and -C18. Lambs fed a lower roughage diet had improved performance and feed efficiency, however, presented reduced polyunsaturated fatty acids (PUFA) concentrations in the meat, especially Σn–3 family. Higher roughage diet and larger peNDF8 particle size improved the concentrations of PUFA while decreased Σn–6:Σn–3 ratio in meat. Larger peNDF8 particle size associated with higher roughage proportion, have reduced animal performance however, it increased protein concentration, a* and C* colour parameter without affecting fatty acids profile of Longissimus lumborum muscle.
The nematode Angiostrongylus cantonensis is the most common cause of neuroangiostrongyliasis (manifested as eosinophilic meningitis) in humans. Gastropod molluscs are used as intermediate hosts and rats of various species are definitive hosts of this parasite. In this study, we identified several environmental factors associated with the presence and abundance of terrestrial gastropods in an impoverished urban region in Brazil. We also found that body condition, age and presence of co-infection with other parasite species in urban Rattus norvegicus, as well as environmental factors were associated with the probability and intensity of A. cantonensis infection. The study area was also found to have a moderate prevalence of the nematode in rodents (33% of 168 individuals). Eight species of molluscs (577 individuals) were identified, four of which were positive for A. cantonensis. Our study indicates that the environmental conditions of poor urban areas (presence of running and standing water, sewage, humidity and accumulated rain and accumulation of construction materials) influenced both the distribution and abundance of terrestrial gastropods, as well as infected rats, contributing to the maintenance of the A. cantonensis transmission cycle in the area. Besides neuroangiostrongyliasis, the presence of these hosts may also contribute to susceptibility to other zoonoses.
Efficient algorithm integration is a key issue in aerial robotics. However, only a few integration solutions rely on a cognitive approach. Cognitive approaches break down complex problems into independent units that may deal with progressively lower-level data interfaces, all the way down to sensors and actuators. A cognitive architecture defines information flow among units to produce emergent intelligent behavior. Despite the improvements in autonomous decision-making, several key issues remain open. One of these issues is the selection, coordination, and decision-making related to the several specialized tasks required for fulfilling mission objectives. This work addresses decision-making for the cognitive unmanned-aerial-vehicle architecture coined as ARCog. The proposed architecture lays the groundwork for the development of a software platform aligned with the requirements of the state-of-the-art technology in the field. The system is designed to provide high-level decision-making. Experiments prove that ARCog works correctly in its target scenario.
Oxidative stress suposses an imbalance between oxidants and antioxidants molecules. Negative and positive family environment have been related with worse and better outcomes respectively in schizophrenic patients.
Our objetive is to determine antioxidant defense in healthy controls and unaffected relatives of early onset psychosis patients and to asses its relationship with familiar environment.
Methods
We included 82 healthy controls (HC) and 14 healthy controls with second degree family history of psychosis (HCWFHP), aged between 9 to 17.
Total antioxidant status and lipid peroxidation test were determined in plasma and antioxidant enzime activities and glutathione levels were determined in erytrocytes.
We used the Global Assesment Functioning scale (GAF) and the Family Environment Scale (FES). The FES is made up of ten subscales: cohesion, expressiveness, conflict, independence, achievement, intellectual-cultural, social, moral, organization and control.
Results
The analyses showed a significant decrease in total antioxidant level in HCWFHP compared with the HC (U Mann Withney = 281.00, p=0.009, effect size= -0.78).
HC and HCWFHP did not differ in the GAF scale, nevertheless the scores of HCWFHP were significantly higher in cohesion and intellectual-cultural dimensions of the FES (p=0.007, p=0.025).
Adjusting by this two FES dimensions, antioxidant status remained significantly different between groups: OR= 10.86, p=0.009.
Discussion
Although we cannot induce causative relations, we can state that family environment is not playing a role in inducing oxidative stress in these subjects. It could be hypothesized that families with affected relatives protect themselves with positive envionmental factors such as cohesion and intellectual-cultural activities.
Allelic variation in the promoter region of the serotonin transporter (5-HTTpro) contributes for the risk of alcohol dependence (AD). The short allele (S) of this polymorphism has been associated with co-occurring clinical features in severe AD such as depression, early onset or impulsivity. We studied the putative link between this allele and relapse in AD.
Methods
60 male alcohol dependent patients were followed for 3 months after withdrawal. Persistent abnormalities in lab tests (GGT and CDT) or failure to show up at scheduled interviews were considered as relapse. PCR amplifying the 5-HTTpro polymorphism from genomic DNA were performed. The impact of the S allele on relapse was assessed by a non-parametric Pearson χ2 test.
Results
67.27 % of the patients relapsed during follow-up. The S allele of the 5-HTTpro was significantly associated with relapse (χ2 = 7.66 ; p < .006) while no other factor influenced relapse.
Conclusions
Responsible for a 5-HT hypo-functioning, the S allele of the 5-HTTpro may be associated with relapse in abstinent alcohol dependent patients, possibly through intermediate phenotypes such as personality features or lack of behavioral inhibition.
Patients with schizophrenia and bipolar disorder appear to have more difficulties with smoking cessation than the general population. Moreover, gender and unsuccessful smoking cessation are associated with depression and negative emotional experience. Less attention has been given to the association of cigarette smoking in women and the use of other substances.
Objectives
To determine the influence of gender and substance abuse on smoking cessation in a long-term follow up after a first psychotic episode.
Method
Patients were evaluated at years 1, 3, and 5 obtaining information about functional outcome, positive and negative symptoms and substance use. At 8th year, functional outcome and use of substance were recorded. Patients were classified in two groups: those who stopped smoking during follow-up, and those who did not stop.
Results
At baseline, rates of tobacco smoking were high with no differences between genders. Difficulty with smoking cessation was associated with female (p = 0.017) and typical antipsychotics (p = 0.032). Those who used alcohol continuously were less likely to stop smoking (p = 0.050) controlling for typical antipsychotics. The interaction with gender was not significant. Continuous cannabis use was not associated with smoking cessation, but women who use cannabis continuously were less able to stop smoking than men (adjusted p = 0.036).
Conclusions
Women are less prone to quit smoking than men during long-term follow-up after the development of psychosis. Different treatments should be considered for men and women in relation to tobacco dependence in patients with psychotic disorder. Treatment for women smokers should probably be more supportive and intensive.
Cloninger's type II is a severe, early-onset, male-limited, genetically influenced, impulsive form of alcoholism. We assessed the association of two gene polymorphisms (TaqI A DRD2 and 5-HTTpro) with Cloninger's typology, as defined by age at onset of alcohol-related problems, and family history of alcohol abuse, which is thought to be more frequent in type II alcoholics.
Methods:
58 male alcohol dependent patients were discriminated according to age at onset of alcohol-related problems and interviewed about family history of alcoholism. Genomic DNA was extracted and PCR amplifying the studied polymorphisms were performed. The associations between DRD2 (A1 or A2 alleles), 5-HTTpro (L and S alleles), family history and typology were assessed by Pearson chi2 analyses.
Results:
While typology was not influenced by any of the studied polymorphisms, a higher rate of general family history of alcohol abuse was still observed in type II patients (χ2= 4.53; p = 0.033). Furthermore, the A1 allele of the DRD2 was significantly associated with paternal history of alcoholism (χ2= 4.66; p = 0.031) and male, first-degree, collateral history of alcoholism (χ2= 4.40; p = 0.036).
Conclusions:
Age at onset as main discriminator between type I and type II does not seem to be influenced by TaqI A DRD2 and 5-5HTTpro polymorphisms. However, the A1 allele of the DRD2 may be a marker of male familial alcoholism, which is in line with previous studies showing association between TaqI A DRD2 with some clinical features of type II alcoholism.
The management of treatment-resistant depression remains a major public health problem. Several acute depression trials suggest that only 45% of the patients achieve remission state with antidepressant monotherapy. An increasing body of evidence is emerging suggesting that multi-action antidepressants might be more effective in treatment-resistant depressed patients than single-action agents. In this context, the purpose of the study was to assess the effectiveness of duloxetine in treatment-resistant major depressed outpatients.
Methods:
We performed a prospective study assessing the efficacy of duloxetine in major depressed outpatients who did not achieve full symptom remission (CGI-S (severity) ≥ 3) after treatment of adequate dose and duration (more than 8 weeks) with at least either one SSRI or the SNRI venlafaxine. We excluded patients with a severe medical illness and a personality disorder. CGI-S was used as a measure of symptom severity and administered before the administration of duloxetine and 6 weeks later. Five patients had been treated with venlafaxine and the others with a SSRI (Fluoxetine, Paroxetine, Citalopram).
Results:
The sample included 10 patients (3 M, 7 F). We observed a very significant decrease in CGI-S scores (5 ± 0.45 to 1.2 ± 0.63, p < 0.0001) after treatment with duloxetine (dose between 20 and 60 mg). Remission was achieved in 90% of the patients. The tolerance was excellent.
Conclusion:
This study suggests the potential interest of duloxetine in treatment-resistant depressed patients.
Resilience enables people to develop and regain mental health in the face of adversity, and is related to recovery. There are no current measures of resilience for Bipolar Disorder (BD).
Aims
To develop and validate a BD specific resilience measure, and examine relationships between resilience and recovery-related variables.
Objectives
(1) Describe the development and psychometric evaluation of the Spanish 23-item Resilience to Bipolar Disorder (RBD) questionnaire. (2) Test relationships between RBD scores and recovery-related variables in BD.
Method
The 41-item RBD questionnaire (developed based on prior qualitative research) was completed by 113 participants with BD, along with measures related to quality of life, functioning and recovery. Exploratory Factor Analysis (EFA) using Principal Axis Factoring with promax rotation was conducted to identify redundant items and underlying factors. Reliability and Confirmatory Factor Analysis (CFA) for the resulting factorial structure were assessed.
Results
EFA identified 23RBD items suitable for retention, structured within five factors. Cronbach αs were all satisfactory (all αs ≥ .76) at both subscale and total score level. Convergent validity was supported through positive correlations between RBDand the Resilience Scale-25. Additionally, the RBD correlated significantlywith quality of life, well-being, personal recovery, functional impairment and symptoms. CFA fit indexes supported the five factor structure of the RBD scale.
Conclusions
TheRBD is a reliable and valid measure of resilience in BD, being associated with measures related to quality of life, functioning and recovery, which is consistent with previous research in resilience and mental health in other psychiatric populations.
