These researchers sought to determine the prevalence of probable mental health disorder and related needs among young people in secure facilities in NZ. The analysis used Massachusetts youth screening instrument – second version (MAYSI‐2) data obtained from the records of 204 young people admitted to a single secure care facility over a 12-month period. Nearly 80% of the cohort scored above the ‘caution’ or ‘warning’ cut‐off point for the MAYSI‐2 score, which was a substantially higher proportion than what has been reported by studies from other countries. Girls, Māori and Pacific Islanders tended to have a higher rate of probable psychopathology.
