An initial evaluation of the Global Review Form as an approach to measuring individual change

Background: Routine assessment of individual change in forensic mental health services is increasingly recognised as important. However, existing tools have been criticised and their periodic use make them unsuited to directly measure the impact of interventions. This paper describes the initial evaluation of the Global Review Form (GRF) as a framework for measuring change over time. Specifically, measurement properties, feasibility and usefulness in routine practice are examined. Method: 28 male service users in three distinct areas of an adult secure service (low secure, locked rehabilitation and high relational support housing) were rated over a 20-week period by their multidisciplinary teams. Findings: The GRF showed promising construct validity and appropriate stability and sensitivity to change across time. It enabled measurement and understanding of individual change over time. Staff feedback suggested the GRF is a useable and practical outcome measuring tool. Conclusions: The GRF shows promise for use as a routine outcome monitoring tool within forensic mental health services.
