Background: Persisting psychotic-like experiences (PLEs) are associated with an increased risk of internalising symptoms in adolescence. Whether this association holds similarly for externalising symptoms, and from mid-childhood, is unclear. This prospective study investigated the extent to which PLE persistence was associated with internalising and externalising psychopathology in a community sample of children aged 9-11 years at study commencement. Methods: 8099 children (mean age 10.4 years) completed questionnaires assessing PLEs, externalising and internalising symptoms. A subsample of 547 children completed reassessment, on average, two years later. Results: Two-thirds (66%) of children reported PLEs at baseline. Approximately two years later, PLEs persisted in 39% of those children. After adjustment for previous psychopathology and other potential confounds, children with persisting PLEs were at higher risk for internalising (odds ratio [OR]=1.94; 95% confidence interval [CI] 1.13-3.34) and externalising (OR=1.97; 95% CI 1.19-3.26) psychopathology than children whose PLEs remitted; and, than children who never presented PLEs. Conclusions: Persistent PLEs from mid-childhood are associated with later internalising and externalising psychopathology in the general population, whereas transitory PLEs may be part of a spectrum of normative childhood development. Interventions that target persistent PLEs may contribute to a reduction in common chi...
While we observed a positive overall association between NNAI disorders and psychosis, this was not consistent across all NNAI disorders. Specific factors, including distinct inflammatory pathways, genetic influences, autoantibodies targeting brain proteins, and exposure to corticosteroid treatment, may therefore underlie this association.
Among male MDOs, R&R participation was associated with improvements in social-cognitive skills, some of which were maintained for up to 12 months post-treatment. Our finding that programme completers do better may reflect pre-treatment patient characteristics. This study establishes that multi-site RCTs can be conducted in medium-secure forensic units.
Studies evaluating the implementation of cognitive skills programs with mentally disordered offenders (MDOs) have reported high dropout rates, but little is known about the factors associated with treatment noncompletion. The authors analyzed data from the first randomized controlled trial of the Reasoning and Rehabilitation (R&R) program with MDOs to determine predictors of treatment dropout. Patients with psychotic disorders were recruited from medium-secure hospitals in the United Kingdom. Fifty percent of the 44 participants allocated to receive R&R prematurely terminated treatment. Program dropout was significantly predicted by scores on the Clinical and Risk Management scales of the Historical, Clinical, Risk Management—20, Factor 2 scores of the Psychopathy Checklist—Screening Version, antisocial personality disorder (ASPD), psychopathy, and recent violence. Psychopathy, ASPD, and recent violence emerged as the strongest predictors of dropout in multivariate analyses. Strategies to improve treatment retention should be targeted at MDOs who display high levels of impulsivity, poor behavioral controls, and antisocial or psychopathic traits.
PurposeThe London Child Health and Development Study (CHADS) is a prospective, longitudinal investigation of children, sampled from the general community aged 9–11 years and assessed biennially, who present premorbid risk markers for schizophrenia. The study aims to characterise developmental trajectories of psychological, cognitive, and biological functioning in at-risk children and identify potential targets for early preventative intervention. This review summarises CHADS findings, discusses these in the context of recent theory regarding aetiology and prevention of schizophrenia, and highlights challenges to be addressed with future research.MethodsWe review (1) epidemiological information on the prevalence and correlates of developmental antecedents of schizophrenia in the general child population, (2) evidence of psychosocial, cognitive, and biological dysfunctions in at-risk children presenting multiple antecedents of schizophrenia and at-risk children with a family history of schizophrenia, and (3) related findings from an associated sample of help-seeking children receiving intervention.ResultsCommunity-based screening of 9–11-year olds identified ~9 % with a triad of antecedents of schizophrenia [including psychotic-like experiences (PLEs)] who are putatively at-risk of psychosis; these children reported greater exposure and responsivity to stressors, impairments in general intelligence and specific cognitive functions, brain structure and function abnormalities, and neuromotor dysfunction. Preliminary evidence suggests distressing PLEs are a viable target for cognitive-behavioural intervention in at-risk children.ConclusionsIntervention in early, premorbid phases of illness might alleviate current difficulties and avert future schizophrenia using benign treatments. The CHADS programme has identified several markers that may index early pathophysiology and constitute potential targets for preventative intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
