Occupational Therapy in Mental Health
The purpose of the author in this study was to investigate the test–retest reliability and predictive validity of new occupational performance assessments. The researcher used a test–retest design with mixed quantitative and qualitative methods. The test–retest reliability of the perceived adequacy of engagement in occupations of priority to participants as measured on the assessments was r (15) = .54, p < .05. Perceived test adequacy predicted 27% [B = .517, t = 2.18, R2 = .27, F (1, 13) = 4.75, p = .048] and retest adequacy predicted 67% [B = .820, t = 5.16, R2 = .67, F (1, 13) = 26.61, p = .000] of variability in the retest frequency of engagement in occupations seen as a priority by research participants. Test satisfaction scores predicted 50% of variability in the test frequency of engagement in occupations [B = .707, t = 3.61, R2 = .50, F (1, 13) = 13.01, p = .003]. It was concluded that adequacy and satisfaction scores could be used by occupational therapists in planning therapeutic interventions to facilitate future performance of occupations seen as important by clients.
