OBJECTIVE: This study aims to evaluate the effectiveness of online group cognitive-behavioral therapy (GCBT) guided by the CAMALEO TOC manual in treating of adolescents with obsessive compulsive disorder (OCD). METHOD: A quasi-experimental study with a single group pre-posttest intervention. Over 12 weeks 11 adolescents aged 11 to 17 years with OCD received weekly online sessions of GCBT based on CAMALEO TOC manual. The Children's Yale-Brown Obsessive-Compulsive Scale was used to assess OCD symptoms severity, the Family accommodation scale for obsessive-compulsive disorder interviewer-rated for family accommodation, the Children's Depression Inventory to assess depression symptoms, the Revised Children's Manifest Anxiety Scale for anxiety, and the Multidimensional Student Life Satisfaction Scale to assess life satisfaction...

OBJECTIVES: To report suicide planning and attempts' in a lifetime among Brazilian physicians and to explore associated risk factors. METHODS: A nation-wide, online survey based on the Tool for the Assessment of Suicide Risk and Satisfaction with Life Scale was conducted among Brazilian physicians (January 2018 - January 2019). Multivariate explored associations of demographics, psychological, and work-related factors on suicide planning and attempts reports. RESULTS: Among 4,148 respondents, 1,946 (53...

BACKGROUND: Bipolar disorder (BD) is a leading cause of disability-adjusted life years in young adults. Complications during prenatal periods have been associated with BD previously. The study aims to examine the association between perinatal factors and BD in order to prevent the risk of developing BD. METHODS: 3,794 subjects from the 1993 Pelotas population-based birth cohort study were included. We assessed 27 initial variables at birth and modelled BD onset at 18 and 22 years...

OBJECTIVE: To perform a meta-analysis and comparison between high-income, and low- and middle-income countries postpartum depression symptoms prevalences. METHODS: PubMed, Embase, Virtual Health Library, Scopus, Web of Science, PsycINFO and CINAHL databases were searched until October 2022 for studies that collected data from pandemic. The metaprop command was used in the Stata statistical software v.12.0 to run a random-effects meta-analysis. RESULTS: A total of 15 studies with 4,788 postpartum women were included...

OBJECTIVES: To study the COVID-19 impact on the routine of patients with obsessive-compulsive disorder (OCD) and putative changes in their symptoms and suicidal-related behavior, mainly in those with cleaning symptoms. METHODS: This was a cross-sectional study in which 58 patients completed an online self-report questionnaire comprising: the Obsessive-Compulsive Inventory-Revised (OCI-R); Coronavirus Stress and Traumatic Events Scale (COROTRAS); Coronavirus Health Impact Survey (CRISIS); Beck Anxiety and Beck Depression Inventories; and suicide-related behaviors questionnaire...

OBJECTIVE: As a secondary trial plan analysis, we aim to examine whether participant characteristics, measured before randomization, modified the effect of a digital intervention designed to improve depressive symptoms (CONEMO - Emotional Control) on recovery from depression that has presented a substantive impact on previous research. METHOD: Mixed logistic regression was used to explore interactions between the treatment arm and subgroups of interest, including suicidal ideation, race/color, age, gender, income, type of mobile phone, alcohol misuse, tobacco use, and diabetes/hypertension)...

OBJECTIVE: Evidence on the relationship of depression with clinical dimensions of schizophrenia remains limited. This cross-sectional study aimed at exploring the association of depression with the Positive and Negative Syndrome Scale (PANSS) dimensions in people with schizophrenia spectrum disorders (SSD). METHODS: Trained assessors administered PANSS to measure core symptoms of schizophrenia and the Calgary Depression Scale for Schizophrenia (CDSS) to measure depressive features...

OBJECTIVE: To clarify if stigma associated with schizophrenia has also been directed towards the ultra-high risk for psychosis (UHR) population, the present review aimed at synthetizing the existing literature to update and extend our understanding on the topic. METHODS: A systematic PRISMA-compliant review was performed in PubMed, Embase, Cochrane and Web of Science for articles published until 30/04/2023, using a combination of search terms describing the at-risk mental states for psychosis and stigma and correlated terms...

OBJECTIVE: The Patient Health Questionnaire-9 (PHQ-9) is a widely used self-reported measure of depression, which was found to display only acceptable psychometric properties. Insufficient attention has been devoted to its clinimetric validity and its clinical utility is still debated, particularly when used for assessing depression severity. This is the first study testing PHQ-9 construct validity and clinical utility based on clinimetric principles. METHODS: An online survey involving a sample of 3,398 participants was conducted...

OBJECTIVE: To evaluate the direct, indirect, and total prospective effects of serum concentrations of [25(OH)D, 25-hydroxycolecalciferol] on depressive symptoms in older adults. METHODS: Data from the second (2013-2015) and third (2017-2019) waves of the EpiFloripa Aging Cohort Study (≥ 60 years) were analyzed. Depressive symptoms were assessed by the 15-item Geriatric Depression Scale (GDS-15). 25(OH)D levels were measured using the microparticle chemiluminescence method...

OBJECTIVE: To evaluate the prevalence of ADHD, comorbidity rates with Disruptive Behavior Disorders (DBD), and main negative outcomes in primary-school students in Nampula, Mozambique. METHODS: We selected a random sample of 748 students for ADHD screening from a population of around 43000 primary school students. The Swanson, Nolan, and Pelham Rating Scale version IV (SNAP-IV scale) was applied to both parents and teachers. All positive screened students (n = 76) and a propensity score-matched random subset of negative screened subjects (n = 76) had a psychiatric evaluation carried out by a child psychiatrist...

OBJECTIVES: The advancement of neuroimaging and genetic research has revealed the presence of morphological abnormalities and numerous risk genes, along with their associations. METHODS: The cortical thickness of 129 schizophrenia patients, 42 unaffected siblings of patients and 112 healthy controls was measured, and the candidate genes were sequenced. Comparisons of cortical thickness (including 68 regions of Desikan-Kiliany atlas) and genetic variants (within 108 risk genes for schizophrenia) among the three groups were made, and correlation analyses were performed between cortical thickness, clinical symptoms, cognitive tests like N-back and logical memory test and genetic variants...

OBJECTIVE: To investigate risk factors associated with impaired attention-related executive functions (EFs) at age 11 and working memory at age 15. METHODS: Data from the population-based 2004 Pelotas Birth Cohort was analyzed at ages 11 (N=3,582) and 15 (N=1,950). The study measured attentional control, cognitive flexibility, and selective attention using the Daily Attention Test for Children. Spatial working memory was assessed by the Cambridge Automated Neuropsychological Test Battery...

OBJECTIVE: The objective of the present study is to adapt and present validity evidence based on the internal structure of the Mind-Wandering Questionnaire (MWQ) for the Brazilian context. METHODS: A total of 2682 Brazilian adults from different regions of the country have taken part in this study. Confirmatory factor analyses and multigroup confirmatory factor analyses (MGCFA) were performed to assess MWQ factor structure. McDonald's Omega (ω) was generated to provide reliability indexes...
