Key Takeaway Key Takeaway: New occupational performance assessments show high test-retest reliability and predictive validity, aiding occupational therapists in planning interventions to improve clients' engagement in priority occupations.
Abstract
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.
