Identifying studies examining the validity of instruments for use as outcome measures in child and adolescent forensic mental health services: a systematic review.

BACKGROUND

Outcome measurement in child and adolescent forensic mental health services can support service improvement, research, and patient progress evaluation. This systematic review aimed to identify studies which validate structured instruments available for use as outcome measures in the child and adolescent forensic mental health service cohort and assess the quality of these studies.

METHODS

A systematic review was conducted following PRISMA guidelines. Studies were identified by searching six online databases in November 2023. The quality and risk of bias of each study meeting inclusion criteria was independently assessed by two authors using the Crowe Critical Appraisal Tool. Results were synthesised narratively.

RESULTS

A total of eight studies were identified which met inclusion criteria. These looked at six instruments which primarily focused on outcome measures in the areas of treatment motivation, level of functioning, psychiatric symptoms, care needs and response to social situations. Papers scored between 17/40 and 30/40 on the Crowe Critical Appraisal Tool. Studies were rated as low (n = 1), moderate (n = 6), high (n = 1) or very high quality (n = 0).

CONCLUSIONS

Despite the large number of structured instruments potentially available, evidence for their use as outcome measures in child and adolescent forensic mental health services is limited. Future research should aim to validate current structured instruments for use in the forensic child and adolescent setting, with consideration of whether new instruments should be developed specifically for this group. Such instruments should be developed with both young people as service users and professionals who will be utilising the instrument in mind.
