Background Among youth with psychiatric disorders, the transition from child to adult mental health services is a period of vulnerability to discontinuous care and service disengagement. Regular assessment of transition readiness has been identified as a core component of transition planning, contributing to successful care transitions. The Transition Readiness Assessment Questionnaire (TRAQ) 5.0 is a 20‐item questionnaire that measures transition readiness in youth preparing to transition to adult care. Although the TRAQ has been validated and used across many health settings, it has not been validated in youth with primarily mental health concerns. The objective of this study was to validate the TRAQ for use among youth accessing mental health services. Methods This study used the Longitudinal Youth in Transition Study baseline cohort, which consists of 237 clinically referred youth (aged 16–18 years) receiving outpatient mental health treatment. Psychometric evaluation of the TRAQ 5.0 included confirmatory factor analysis (CFA), assessment of internal consistency, testing convergent validity using the Dimensions of Emerging Adulthood (IDEAS) and Difficulty in Emotional Regulation (DERS) scales, criterion validity using a question on whether the participant had talked about transition with their clinician and known‐group testing based on age. Results The CFA indicated adequate fit of the five‐factor TRAQ structure. The overall scale (=.86) and three of the subscales demonstrated adequate internal consistency. As hypothesized, overall TRAQ scores were higher for youth who had discussed transition and those aged 18. Small correlations were found between the overall TRAQ score and measures of developmental maturity (IDEAS) and emotional awareness (DERS); however, certain subscales did not demonstrate correlation with these constructs. Conclusions The TRAQ 5.0 appears to be valid tool to assess the transition readiness of youth in outpatient mental health services. Additional work needs determine whether findings are similar among specific mental health conditions, including substance use disorders and psychotic disorders.
