A Scoping Review of the Use of Rasch Analysis Methodology to Strengthen Self-Report Occupational Therapy Mental Health Measures

Abstract Self-report measures can be used to accurately assess client outcomes, providing evidence for the effectiveness of occupational therapy. Rasch analysis, a psychometric research methodology, is increasingly being used to validate self-report measures, however, the extent of its use within mental health occupational therapy is unknown. To address this, a scoping review that included twenty articles published between 2001 and 2019 was conducted. This review quantifies the increase in use of Rasch analysis in this field and finds heterogeneity in the analysis techniques implemented. As the use of Rasch analysis increases, it offers benefits to strengthen self-report measures within mental health occupational therapy.
