Healy, Colm Brannigan, Ross Dooley, Niamh Coughlan, Helen Clarke, Mary Kelleher, Ian Cannon, Mary Childhood and adolescent psychotic experiences and risk of mental disorder: a systematic review and meta-analysis. <div><h4>BACKGROUND: </h4><p>Psychotic experiences (PEs) are common in childhood and adolescence and their association with mental disorders is well-established. We aim to conduct a quantitative synthesis the literature on the relationship between childhood and adolescent PEs and (i) any mental disorder; and (ii) specific categories of mental disorder, while stratifying by study design.</p><h4>METHOD: </h4><p>Three electronic databases (PUBMED, PsycINFO and EMBASE) were searched from inception to August 2017 for all the published literature on childhood and adolescent PEs and mental disorder (outcome) in non-help-seeking community samples. Study quality was assessed using a recognised quality assessment tool for observational studies. Two authors conducted independent data extraction. Pooled odds ratios were calculated for mental disorders using random-effects models. Additional analyses were conducted investigating different categories of mental disorder while stratifying by study design.</p><h4>RESULTS: </h4><p>Fourteen studies from 13 community samples (n = 29 517) were identified with 9.8% of participants reporting PEs. PEs were associated with a three-fold increased risk of any mental disorder [odds ratio (OR) 3.08, confidence interval (CI) 2.26-4.21, k = 12]. PEs were associated with four-fold increase risk of psychotic disorder (OR 3.96, CI 2.03-7.73, population-attributable-fraction: 23.2%, k = 5). In addition, PEs were associated with an increased risk of affective disorders, anxiety disorders, behavioural disorders and substance-use disorders. Few longitudinal studies have investigated childhood and adolescent PEs and subsequent non-psychotic disorders which limited a meaningful synthesis and interpretation of these results.</p><h4>CONCLUSION: </h4><p>This meta-analysis confirms that PEs are prevalent in childhood and adolescent community samples and are associated with a variety of mental disorders beyond psychotic disorders. Further longitudinal research is necessary to fully determine the longitudinal relationship between PEs and non-psychotic disorders.</p></div> Psychotic Experiences;childhood;adolescent;mental disorders;Psychiatry (incl.
