Comparisons of outcomes between different age groups attending a specialist mental health service for children and young people in care

Abstract

Objective: Children and adolescents in care experience higher rates of mental illness. No studies have looked at differences in treatment effect amongst age groups for children/young people in care accessing mental health services. This study aims to determine if age is associated with outcomes for children and adolescents in care receiving treatment from a specialist mental health service in Queensland, Australia. Method: This 5-year retrospective cohort study consisted of a sample of 1338 children and adolescents in care aged 0–17 with pre- and post-treatment data. The Children’s Global Assessment Scale (CGAS) and the Health of the Nations Outcome Scale for Children and Adolescents (HoNOSCA) were used to assess functioning and mental health outcomes. Results: Data analysis revealed significant differences between the age groups. Age 0–4 also showed significantly greater improvement on a number of domains when compared with older age groups, including overactivity and attention, scholastic and language skills, emotional symptoms, peer relationships, and family life and relationships. Conclusion: This study demonstrated positive outcomes for all ages, yet better outcomes for the younger age groups in a cohort of children and adolescents in care attending a specialist mental health service. It highlights the importance of providing mental health interventions to children/young people in care, particularly age 0–4. Further, it calls for validated measures for young children to be utilised across mental health services to aid research in this area and optimise outcomes for this vulnerable population.
