The traditional view that mental disorders are distinct, categorical has been challenged by evidence highly comorbid and exist on a continuum (e.g., Caspi et al., 2014; Tackett 2013). first objective of this study was to use structural equation modeling model the structure psychopathology in an adolescent community-based sample (N = 2,144) including conduct disorder, attention-deficit/hyperactivity disorder (ADHD), oppositional-defiant (ODD), obsessive-compulsive eating disorders, substance...
Selective school-based alcohol prevention programs targeting youth with personality risk factors for addiction and mental health problems have been found to reduce substance use misuse in those elevated profiles.To report 24-month outcomes of the Teacher-Delivered Personality-Targeted Interventions Substance Misuse Trial (Adventure trial) which school staff were trained provide interventions students 1 4 high-risk (HR) profiles: anxiety sensitivity, hopelessness, impulsivity, sensation...
Alcohol and cannabis misuse are related to impaired cognition. When inferring causality, four nonexclusive theoretical models can account for this association: 1) a common underlying vulnerability model; 2) neuroplasticity model in which impairment is concurrent with changes substance use but temporary because of neuroplastic brain processes that restore function; 3) neurotoxicity long-term consequential use; 4) developmental sensitivity hypothesis age-specific effects. Using developmentally...
Background This study assessed the validity, sensitivity, and specificity of Substance Use Risk Profile Scale ( SURPS ), a measure personality risk factors for substance use other behavioral problems in adolescence. Methods The concurrent predictive validity was tested sample 1,162 adolescents (mean age: 13.7 years) using linear logistic regressions, while its sensitivity were examined receiver operating characteristics curve analyses. Results Concurrent tests showed that all 4 brief...
Background Using longitudinal and prospective measures of psychotic experiences during adolescence, we assessed the risk developing psychosis in three groups showing low, increasing elevated associated with bullying by peers cannabis use a UK sample adolescents. Method Data were collected self-report from 1098 adolescents (mean age 13.6 years; 60.9% boys) at five separate time points, equally separated 6 months, across 24-month period. General growth mixture modelling identified distinct...
Aims To examine the effectiveness of a personality-targeted intervention program (Adventure trial) delivered by trained teachers to high-risk (HR) high-school students on reducing marijuana use and frequency use. Design A cluster-randomized controlled trial. Setting Secondary schools in London, UK. Participants Twenty-one secondary were randomized (n = 12) or control 9) conditions, encompassing total 1038 HR ninth grade [mean (standard deviation) age 13.7 (0.33) years]. Interventions Brief...
Objective: This study aims to explore the mechanisms of personality-targeted intervention effects on problematic drinking, internalising and externalising symptoms. Method:As part a cluster-randomised trial, 1210 high-risk students (mean age 13.7 years) in 19 London high schools (42.6% white, 54% male) were identified using Substance Use Risk Profile Scale.Intervention school participants invited participate personality-matched interventions by trained staff.MacKinnon's products coefficients...
Substance use and binge drinking during early adolescence are associated with neurocognitive abnormalities, mental health problems an increased risk for future addiction. The trial aims to evaluate the protective effects of evidence-based substance prevention programme on onset alcohol drug in adolescence, as well cognitive, addiction outcomes over 5 years.Thirty-eight high schools will be recruited, a final sample 31 assigned intervention or control conditions (3826 youth). Brief...
The authors sought to model the different trajectories of psychotic-like experiences (PLE) during adolescence and examine whether longitudinal relationship between cannabis use PLE is mediated by changes in cognitive development and/or change anxiety or depression symptoms.A total 2,566 youths were assessed every year for 4-years (from 13- 16-years age) on clinical, substance outcomes. Latent class growth models identified three PLE: low decreasing (83.9%), high (7.9%), moderate increasing...
Objective To investigate the role of personality factors and attentional biases towards emotional faces, in establishing concurrent prospective risk for mental disorder diagnosis adolescence. Method Data were obtained as part IMAGEN study, conducted across 8 European sites, with a community sample 2257 adolescents. At 14 years, participants completed an variant dot-probe task, well two measures, namely Substance Use Risk Profile Scale revised NEO Personality Inventory. 16 their parents...
