A systematic review and meta-analysis of the type and prevalence of mental health disorders and symptoms among children living in residential care

Research suggests that among all children living in social care, those in residential care have the highest mental health need. This systematic review and meta-analysis is the first to establish the type and prevalence of mental health disorders and symptoms among children in residential care. A systematic search of PsycINFO, MEDLINE, Scopus, Web of Science Core Collection, ASSIA, IBSS and grey literature databases from January 1989 to July 2022 was conducted ( N = 11, 246). Articles were eligible for inclusion where they: (1) included a sample living in residential provision similar to that provided in the UK, (2) used standardised screening tools or psychiatric assessments, using diagnostic classification systems, and (3) reported prevalence estimates. Pooled prevalence estimates were calculated using random-effects meta-analysis. 21 articles with prevalence rates for a total of 4287 children, adolescents and young adults were included. Almost half the children had symptoms indicative of a probable mental health disorder (46%; 95% confidence interval (CI) 35–58). Externalising problems (49%; 95% CI 34–65), were more common than internalising problems (39%; 95% CI 26–53) and prevalence rates for conduct disorder (34%; 95% CI 17–55), depression (26%; 95% CI 18–35), emotional symptoms (17%; 95% CI 8–28), and somatic symptoms (14%; 95% CI 8–20) were estimated. The findings provide evidence that the prevalence of mental health disorders and symptoms are particularly high among children in residential care. These pooled estimates should be interpreted with caution due to high heterogeneity and further epidemiological research is needed to guide policy in different countries.
