Purpose: This study examines the association between mental health problems in adolescence and general practice (GP) costs during adulthood up to age 50 in the UK., Methods: We conducted secondary analyses of three British birth cohorts (individuals born in single weeks in 1946, 1958 and 1970). Data for the three cohorts were analysed separately. All respondents who participated in the cohort studies were included. Adolescent mental health status was assessed in each cohort using the Rutter scale (or, for one cohort, a forerunner of that scale) completed in interviews with parents and teachers when cohort members were aged around 16. Presence and severity of conduct and emotional problems were modelled as independent variables in two-part regression models in which the dependent variable was costs of GP services from data collection sweeps up to mid-adulthood. All analyses were adjusted for covariates (cognitive ability, mother's education, housing tenure, father's social class and childhood physical disability)., Results: Adolescent conduct and emotional problems, particularly when coexisting, were associated with relatively high GP costs in adulthood up to age 50. Associations were generally stronger in females than males., Conclusion: Associations between adolescent mental health problems and annual GP cost were evident decades later, to age 50, suggesting that there could be significant future savings to healthcare budgets if rates of adolescent conduct and emotional problems could be reduced., Trial Registration: Not applicable., (© 2023.

Objective: Electroconvulsive therapy (ECT) is commonly indicated for refractory psychiatric disorders. However, response comparison across diagnoses is scantly investigated. Here, we aimed to evaluate the relative impact of diagnosis and clinical staging as response predictors in a cross-diagnostic sample., Methods: We investigate, in a retrospective cohort of adult inpatients (N=287) who underwent at least six sessions of ECT, predictors of complete response (a clinical global impression of 1) to ECT. We use adjusted regression models to estimate the impact of clinical diagnosis and staging on complete response and dominance analysis to assess the relative importance of these predictors., Results: Those with a depressive episode as a primary indication for treatment were more likely than all the other groups to have complete improvement, while those with psychosis were the least likely; clinical stage had a significant influence on outcome in all diagnoses. A diagnosis of psychosis stood as the strongest predictor of non-response., Conclusion: An indication of ECT for psychosis (mostly schizophrenia) had a dominant impact in our cohort, indicating a worse chance of response. We also demonstrate that clinical staging can aggregate information on response to electroconvulsive therapy that is independent of clinical diagnosis., Competing Interests: The authors report no conflicts of interest.

Individual differences in cognitive abilities emerge early during development, and children with poorer cognition are at increased risk for adverse outcomes as they enter adolescence. Caregiving plays an important role in supporting cognitive development, yet it remains unclear how specific types of caregiving behaviors may shape cognition, highlighting the need for large-scale studies. In the present study, we characterized replicable yet specific associations between caregiving behaviors and cognition in two large sub-samples of children ages 9-10 years old from the Adolescent Brain Cognitive Development Study ® (ABCD). Across both discovery and replication sub-samples, we found that child reports of caregiver monitoring (supervision or regular knowledge of the child's whereabouts) were positively associated with general cognition abilities, after covarying for age, sex, household income, neighborhood deprivation, and parental education. This association was specific to the type of caregiving behavior (caregiver monitoring, but not caregiver warmth), and was most strongly associated with a broad domain of general cognition (but not executive function or learning/memory). Additionally, we found that caregiver monitoring partially mediated the association between household income and cognition, furthering our understanding of how socioeconomic disparities may contribute to disadvantages in cognitive development. Together, these findings underscore the influence of differences in caregiving behavior in shaping youth cognition.

Background: Although low-grade inflammation is associated with onset and persistence of depression, most biomarkers display modest predictive effects. GlycA (glycoprotein acetylation) is a unique metabolomic composite of pro-inflammatory acute-phase glycoproteins. We hypothesized that GlycA levels would predict depression incidence, remission and persistence, with higher accuracy than high-sensitivity c-reactive protein (hsCRP). We also explored the additive predictive value of GlycA above and beyond hsCRP., Methods: Cohort design using the sample of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)'s São Paulo site. Baseline GlycA and hsCRP levels were measured in blood plasma. Depression incidence, remission, and persistence were assessed using the Clinical Interview Scheduled Revised (CIS-R) at two time points separated by a mean of 3.8 years. Multivariable Poisson, logistic and linear regression models were used for prediction. Models were adjusted for sociodemographic and clinical confounders, including age, gender, ethnicity, education, cardiovascular assessments, antidepressant and anti-inflammatory drug use, anxiety disorders, alcohol use, and body mass index., Results: We included 4,364 participants (53.2% females, mean age 51.4 ± 8.9 years) with no autoimmune disorders. GlycA robustly predicted depression persistence (relative risk of 7.28, 95% confidence interval 1.33-45.57, p = 0.023 in the fully-adjusted model), but not depression onset. Although hsCRP also predicted depression persistence, its effects were fully explained by confounders and by GlycA levels. GlycA also predicted worsening of depressive symptoms in depressed patients and depression persistence vs. remission in fully-adjusted models., Limitations: Brief depressive episodes could not be measured by our assessments., Conclusions: GlycA might be a new inflammatory prognosis biomarker for depression., Competing Interests: Declaration of Competing Interest None, (Copyright © 2020 Elsevier B.V.

Objective: To investigate how a set of positive social and personality characteristics called 'positive attributes' affects the emergence and persistence of Psychotic Experiences (PE) in adolescence., Method: We used data from a community-based Brazilian High-Risk Cohort (HRC). 2511 6-12 year-old children were evaluated at baseline, and 80.05% completed a 3-year follow-up interview. At baseline, childhood trauma was assessed using parent- and self-report, and positive attributes were assessed by parent-report. Trained psychologists rated self-reported PE at both time points. Linear models evaluated the effect of childhood trauma and positive attributes on PE at follow-up. Mediation models tested i.) the indirect effect of positive attributes on the association between childhood trauma and follow-up PE and, ii.) the indirect effect of childhood trauma and positive attributes on the relationship between PE at baseline and follow-up., Results: Higher levels of baseline PE (B = 0.157, p < .001) and higher childhood trauma (B = 0.110, p < .001) were associated with increased follow-up PE. Higher positive attributes predicted lower PE after 3 years, adjusting for the prevalence of baseline PE and childhood trauma (B = -0.042, p < .022). Positive attributes partially mediated the relationship between childhood trauma and follow-up PE. The indirect pathway of childhood trauma and positive attributes mediated the association between baseline and follow-up PE., Conclusions: Higher levels of positive social and behavioral traits in childhood may diminish the subsequent emergence of PE. As these attributes can be promoted, our findings suggest that positive attributes may represent a novel target for preventive interventions in children at risk of developing PE., (Copyright © 2018 Elsevier B.V.

Objective:: To distinguish normative fears from problematic fears and phobias., Methods:: We investigated 2,512 children and adolescents from a large community school-based study, the High Risk Study for Psychiatric Disorders. Parent reports of 18 fears and psychiatric diagnosis were investigated. We used two analytical approaches: confirmatory factor analysis (CFA)/item response theory (IRT) and nonparametric receiver operating characteristic (ROC) curve., Results:: According to IRT and ROC analyses, social fears are more likely to indicate problems and phobias than specific fears. Most specific fears were normative when mild; all specific fears indicate problems when pervasive. In addition, the situational fear of toilets and people who look unusual were highly indicative of specific phobia. Among social fears, those not restricted to performance and fear of writing in front of others indicate problems when mild. All social fears indicate problems and are highly indicative of social phobia when pervasive., Conclusion:: These preliminary findings provide guidance for clinicians and researchers to determine the boundaries that separate normative fears from problem indicators in children and adolescents, and indicate a differential severity threshold for specific and social fears.
