High rates of comorbidities and poor validity disorder diagnostic criteria for mental disorders hamper advances in health research. Recent work has suggested the utility continuous cross-cutting dimensions, including general psychopathology specific factors externalizing internalizing (e.g., distress fear) syndromes. The current study evaluated reliability competing structural models examined external best fitting model on basis family risk child global executive function (EF). A community...
This study examined the psychometric properties of Brazilian-Portuguese version Generalized Anxiety Disorder GAD-7 questionnaire in a community sample (n = 206) Brazilian adults.The was 41% female, with mean age 21.10 (SD 4.49), 75.6% from colleges/universities.Results confi rmatory factor analysis provided support to original unidimensional model context.Analyses Variance (ANOVA) showed that scores were signifi cantly different between males and females, females scoring higher than...
The objective of this study is to present the rationale, methods, design and preliminary results from High Risk Cohort Study for Development Childhood Psychiatric Disorders. We describe sample selection components each phases study, its instruments, tasks procedures. Preliminary are limited baseline phase encompass: (i) efficacy oversampling procedure used increase frequency both child family psychopathology; (ii) interrater reliability (iii) role differential participation rate. A total...
The Childhood Trauma Questionnaire (CTQ) is internationally accepted as a key tool for the assessment of childhood abuse and neglect experiences. However, there are relative few psychometric studies available some authors have proposed two different factor solutions. We examined dimensional structure internal consistency Brazilian version CTQ. A total 1,925 participants from eight clinical non-clinical samples including adolescents, adults elders were considered in this study. First, we...
Preliminary research implicates threat-related attention biases in paediatric anxiety disorders. However, major questions exist concerning diagnostic specificity, effects of symptom-severity levels, and threat-stimulus exposure durations paradigms. This study examines these issues a large, community school-based sample. Method A total 2046 children (ages 6-12 years) were assessed using the Development Well Being Assessment (DAWBA), Childhood Behavior Checklist (CBCL) dot-probe tasks....
Abstract Exposure to childhood adversity has been consistently associated with poor developmental outcomes, but it is unclear whether these associations vary across different forms of adversity. We examined cross‐sectional and longitudinal between threat deprivation cognition, emotional processing, psychopathology in a middle‐income country. The sample consisted 2511 children adolescents (6–17 years old) from the Brazilian High‐Risk Cohort for Mental Conditions. Parent reports on were used...
Abstract Extracellular vesicles (EVs) are present in numerous peripheral bodily fluids and function critical biological processes, including cell-to-cell communication. Most relevant to the study, EVs contain microRNAs (miRNAs), initial evidence from field indicates that miRNAs detected circulating have been previously associated with mental health disorders. Here, we conducted an exploratory longitudinal cross-sectional analysis of miRNA expression serum adolescent participants. We analyzed...
The present study was designed to verify the efficacy of cognitive-behavioral group therapy (CBGT) in reducing obsessive-compulsive symptoms and intensity overvalued ideas, as well improving patient's quality life.Forty-seven patients meeting DSM-IV criteria for disorder (OCD) were randomly assigned either 12 weekly CBGT sessions or a waiting list (control group). Treated followed three months.There significant reduction Yale-Brown Obsessive-Compulsive Scale (p < 0.001), National Institute...
The serotonin selective reuptake inhibitors are increasingly being used for the treatment of panic disorder. We examined efficacy and safety inhibitor sertraline hydrochloride in patients with disorder.One hundred seventy-six nondepressed outpatients disorder, or without agoraphobia, from 10 sites followed identical protocols that a flexible-dose design. After 2 weeks single-blind placebo, were randomly assigned to double-blind, either (50-200 mg/d) placebo.Sertraline-treated exhibited...
Article Abstract Background: Cognitive-behavioral group therapy (CBGT) and serotonin reuptake inhibitors have proven efficacy in reducing symptoms of obsessive-compulsive disorder (OCD). There is no consensus about which these forms treatment more effective. This study was conducted to evaluate the CBGT as compared that sertraline OCD symptoms. Method: Fifty-six outpatients with an diagnosis, according DSM-IV criteria, participated randomized clinical trial: 28 took 100 mg/day underwent for...
Adverse early-life environment is associated with anxiety-like behaviors and disorders. Brain-derived neurotrophic factor (BDNF) sensitive to this could be a marker of underlying brain changes. We aimed at evaluating the development in rat model early adversity, as well possible association BDNF levels. Similar associations were investigated sample adolescent humans. For study, Wistar litters divided into: stress (ELS, limited access nesting material) control groups. Maternal behavior was...
Background Both inhibitory-based executive functioning (IB-EF) and basic information processing (BIP) deficits are found in clinic-referred attention deficit hyperactivity disorder (ADHD) samples. However, it remains to be determined whether: (1) such occur non-referred samples of ADHD; (2) they specific (3) the co-morbidity between ADHD oppositional defiant disorder/conduct (ODD/CD) has additive or interactive effects; (4) IB-EF primary due BIP deficits. Method We assessed 704 subjects (age...
Objective: Alzheimer’s disease is a heritable neurodegenerative disorder in which early-life precursors may manifest cognition and brain structure. The authors evaluate this possibility by examining, youths, associations among polygenic risk score for disease, cognitive abilities, hippocampal volume. Method: Participants were children 6–14 years of age two Brazilian cities, constituting the discovery (N=364) replication samples (N=352). As an additional replication, data from Canadian sample...
Background. Taxometric and behavioral genetic studies suggest that attention deficit hyperactivity disorder (ADHD) is best modeled as a dimension rather than category. We extended these analyses by testing for the existence of putative ADHD-related deficits in basic information processing (BIP) inhibitory-based executive function (IB-EF) individuals subclinical full clinical ranges. Consistent with dimensional model, we predicted would be expressed across spectrum, degree linearly related to...
Abstract The goal of this study was to compare brain structure between individuals with generalized anxiety disorder (GAD) and healthy controls. Previous studies have generated inconsistent findings, possibly due small sample sizes, or clinical/analytic heterogeneity. To address these concerns, we combined data from 28 research sites worldwide through the ENIGMA-Anxiety Working Group, using a single, pre-registered mega-analysis. Structural magnetic resonance imaging children adults (5–90...
In this study we assessed the quality of life patients with panic disorder, particular attention to influence anxiety and depression comorbidity on life. Findings were compared established general population norms as well for chronic medical conditions major depression. The Medical Outcomes Study Short-Form Health Survey (SF-36) was administered disorder entering clinical trials or treatment in an outpatient disorders program. Subjects 73 consecutive a primary diagnosis without current...
