- Abstract
Objective: Adolescent psychotic‐like experiences predict the onset of psychosis, but also predict subsequent non‐psychotic disorders. Therefore, it is crucial to better understand the aetiology of psychotic‐like experiences. This study examined whether (a) child emotional and behavioural problems at 3 and 6 years, or (b) childhood adversities were associated with psychotic‐like experiences at age 10 years. Method: This prospective study was embedded in the Generation R Study; 3984 children (mean age 10 years) completed a psychotic‐like experiences questionnaire. Mothers reported problems of their child at ages 3, 6 and 10 years. Additionally, mothers were interviewed about their child's adversities. Results: Psychotic‐like experiences were endorsed by ~20% of children and predicted by both emotional and behavioural problems at 3 years (e.g. emotional‐reactive problems: ORadjusted = 1.10, 95% CI: 1.06–1.15, aggressive behaviour: ORadjusted = 1.03, 95% CI: 1.02–1.05) and 6 years (e.g. anxious/depressed problems: ORadjusted = 1.11, 95% CI: 1.06–1.15, aggressive behaviour: ORadjusted = 1.04, 95% CI: 1.04–1.05). Childhood adversities were associated with psychotic‐like experiences (>2 adversities: ORadjusted = 2.24, 95% CI: 1.72–2.92), which remained significant after adjustment for comorbid psychiatric problems. Conclusion: This study demonstrated associations between early adversities, childhood emotional and behavioural problems and pre‐adolescent psychotic‐like experiences, which will improve the understanding of children at increased risk of severe mental illness.
