| Abstract |
Aims Community-based research suggests that psychotic experiences (PEs) in children and adolescents are common. PEs are suspected to be more common in clinical samples but exact prevalence is unknown. Research into the prevalence, pattern and implications of PEs in clinical samples could provide a valuable opportunity for intervention. The aim of this systematic review and meta-analysis is to determine the prevalence of psychotic experiences in children and adolescents presenting to mental health services. Method Five electronic databases (MEDLINE, EMBASE, PsycINFO, CINAHL and Web of Science) were searched from inception to March 2024 for literature relevant to Childhood and Adolescent PEs and mental health service use. Literature search, data extraction and quality review were conducted independently by two reviewers. Random effects model was used to calculate a meta-analytic estimate of PE prevalence across studies. Results and Conclusions 18 studies from different clinical populations (n = 6126) were identified, with 54% of patients experiencing PEs. Excluding studies that did not explicitly exclude diagnostic threshold psychosis, the PE prevalence was 38%. Prevalence was consistent across secondary, tertiary and inpatient care. PE prevalence in children and adolescents presenting to mental health services is higher compared to previous meta-analysis of prevalence in community samples. Implications include the importance of enquiring about PEs during clinical encounters and provides evidence to normalise these experiences to patients/families. Given the high prevalence, and association of PEs with adverse outcomes, further research is required to identify clinical markers of particular risk and whether PE targeted monitoring or treatment is beneficial. |
