OBJECTIVE: The question of how to best conceptualize health anxiety (HA) from a diagnostic and etiological perspective remains debated. The aim was to examine the relationship between HA and the symptoms of anxiety and obsessive-compulsive-related disorders in a normative twin population. METHOD: Four hundred and ninety-six monozygotic adult twin pairs from the Australian Twin Registry participated in the study (age, 34.4 ± 7.72 years; 59% females). Validated scales were used to assess each domain...

OBJECTIVE: To compare pupil responses in depressed patients with a seasonal pattern, depressed patients without a seasonal pattern and healthy controls as a function of daylight hours on the testing day. METHOD: Patients suffering from a major depressive episode were included in wintertime. The pupil light reflex was measured at inclusion and in the following summer using a binocular pupillometer. A protocol of low (1 lux) and high (400 lux) intensity red and blue lights was used to assess rod, cone and melanopsin-containing intrinsic photosensitive retinal ganglion cell input to the pupil reflex...

OBJECTIVE: This study aimed to systematically appraise the meta-analyses of observational studies on risk factors and peripheral biomarkers for schizophrenia spectrum disorders. METHODS: We conducted an umbrella review to capture all meta-analyses and Mendelian randomization studies that examined associations between non-genetic risk factors and schizophrenia spectrum disorders. For each eligible meta-analysis, we estimated the summary effect size estimate, its 95% confidence and prediction intervals and the I2 metric...

OBJECTIVE: To investigate efficacy, patient acceptability and feasibility of formulation-based cognitive-behavioural therapy (CBT) for adults with attention-deficit hyperactivity disorder (ADHD). NICE guidelines for adult ADHD recommend further research into psychological treatments. METHOD: Sixty participants with adult ADHD were randomly allocated to treatment as usual (TAU) vs. TAU plus up to 16 sessions of individual formulation-based CBT for ADHD. RESULTS: Adding formulation-based CBT to TAU for ADHD significantly improved ADHD symptoms on the Barkley Current Symptoms Scale and scores on the Work and Social Adjustment Scale...

OBJECTIVE: To examine the two constitutes of cortical volume (CV), that is, cortical thickness (CT) and surface area (SA), in individuals with dissociative identity disorder (DID) with the view of gaining important novel insights into the underlying neurobiological mechanisms mediating DID. METHODS: This study included 32 female patients with DID and 43 matched healthy controls. Between-group differences in CV, thickness, and SA, the degree of spatial overlap between differences in CT and SA, and their relative contribution to differences in regional CV were assessed using a novel spatially unbiased vertex-wise approach...

OBJECTIVE: PANSS-8 and PANSS-6 are derived from the 30-item Positive and Negative Syndrome Scale (PANSS-30). We investigate whether PANSS-8 or PANSS-6 is a reliable, valid, sensitive to change measure, and scalable, and whether early improvement using them can predict response/remission. METHOD: Data were from 3 trials for 270 schizophrenia inpatients receiving antipsychotics. Internal consistency, validity, sensitivity to change, and scalability using PANSS-30, PANSS-8, and PANSS-6 at each assessment were examined...

OBJECTIVE: To assess the prospective associations of mood disorders and suicidality in a community sample of young adults from south Brazil. METHOD: Prospective population-based cohort study. Young adults (18-24 years old) were recruited and followed up on 5 years later; people were interviewed at their homes. Suicidality, as well as mood and anxiety disorders, was assessed using the Mini-International Neuropsychiatric Interview. The impact of mood episodes on suicidality was both evaluated when they occurred in the same wave (a current episode) and when suicidality occurred prospectively, with suicidality measured at follow-up (a past episode)...

OBJECTIVE: To establish whether previously identified early-life antecedents of suicide mortality (i.e. low birthweight, younger maternal age, higher birth order, externalizing problems and adversities) are associated with proximal psychiatric disorders and suicidal ideation, which are themselves associated with an increased risk of suicide. METHODS: Participants were from the 1958 British birth-cohort (N = 8905) with information on prenatal/childhood experiences and the Clinical Interview Schedule-Revised at age 45 years...

OBJECTIVE: We aimed at determining whether gender modified associations between ADHD and psychiatric comorbidities in adults. METHOD: We identified adults with ADHD by linking Norwegian national registries and compared them with the remaining adult population (born 1967-1997, ADHD and bipolar during 2004-2015, other psychiatric disorders 2008-2015). Prevalence differences (PDs) and prevalence ratios (PRs) of psychiatric disorders were determined by Poisson regression...

OBJECTIVE: To assess excess mortality among suicide attempters compared to the general population. METHOD: Remaining life expectancy was calculated for a nationwide cohort of all 187 894 persons 18 years or older hospitalised for the first time attempted suicide in Sweden in 1971-2010. RESULTS: Life expectancy was shortened throughout the lifespan for both men and women debuting with suicide attempt. The reduction in life expectancy for men debuting with a suicide attempt at 20 years of age was 18 years while the reduction for men debuting at 50 years of age was 10 years...

OBJECTIVE: To investigate whether trauma exposure moderates the genetic correlation between substance use disorders and psychiatric disorders, we tested whether trauma exposure modifies the association of genetic risks for mental disorders with alcohol misuse and nicotine dependence (ND) symptoms. METHODS: High-resolution polygenic risk scores (PRSs) were calculated for 10 732 US Army soldiers (8346 trauma-exposed and 2386 trauma-unexposed) based on genome-wide association studies of bipolar disorder (BD), major depressive disorder, and schizophrenia...

OBJECTIVE: Recently, the American Psychiatric Association (DSM-5) and the World Health Organization (ICD-11) have both revised their formulation of post-traumatic stress disorder (PTSD). The primary aim of this study was to compare DSM-5 and ICD-11 PTSD prevalence and comorbidity rates, as well as the level of disability associated with each diagnosis. METHOD: This study was based on a representative sample of adult Ukrainian internally displaced persons (IDPs: N = 2203)...

OBJECTIVE: It still remains unclear whether psychotic features increase the risk of suicidal attempts in major depressive disorder. Thus, we attempted, through a systematic review coupled with a meta-analysis, to elucidate further whether unipolar psychotic depression (PMD) compared to non-PMD presents higher levels of suicidal attempts. METHOD: A systematic search was conducted in PubMed, EMBASE, PsycINFO as well as in various databases of the so-called gray literature for all studies providing data on suicidal attempts in PMD compared to non-PMD, and the results were then subjected to meta-analysis...

OBJECTIVE: The neurodevelopmental hypothesis of psychosis suggests that disrupted white matter (WM) maturation underlies disease onset. In this longitudinal study, we investigated WM connectivity and compared WM changes between individuals at ultra-high-risk for psychosis (UHR) and healthy controls (HCs). METHOD: Thirty UHR individuals and 23 HCs underwent MR diffusion tensor imaging before and after 12 months of non-manualized standard care. Positive and negative symptoms and level of functioning were assessed...

OBJECTIVE: To examine the associations between personality traits and suicidal ideation (SI) and attempt (SA) in mood disorder patients and community controls. METHOD: We recruited 365 bipolar, 296 major depressive disorder patients, and 315 community controls to assess their lifetime suicidality. Participants filled out self-reported personality questionnaires to collect data of personality traits, including novelty seeking (NS), harm avoidance (HA), extraversion (E), and neuroticism (N)...

OBJECTIVE: The impact of religious/spiritual activities on clinical outcomes in patients with serious mental illnesses remains controversial, which was addressed in this international cross-sectional study. METHOD: Three-hundred sixty-nine subjects were recruited from Austria (n = 189) and Japan (n = 180), consisting of 112 outpatients with paranoid schizophrenia, 120 with bipolar I disorder (DSM-IV), and 137 healthy controls. Religiosity was assessed in terms of attendance and importance of religious/spiritual activities, while resilience was assessed using the 25-item Resilience Scale...

OBJECTIVE: Academic performance in youth, measured by grade point average (GPA), predicts suicide attempt, but the mechanisms are not known. It has been suggested that general intelligence might underlie the association. METHODS: We followed 26 315 Swedish girls and boys in population-representative cohorts, up to maximum 46 years of age, for the first suicide attempt in hospital records. Associations between GPA at age 16, IQ measured in school at age 13 and suicide attempt were investigated in Cox regressions and mediation analyses...
