Background: The Occupational Resilience Measure (ORM 1.0) is a 20-item, multidimensional self-report tool for measuring occupational resilience, a construct defined as an individual's ability to persist in performing occupations despite barriers. Objective: This study evaluated test-retest reliability and internal consistency and explored the extent to which ORM 1.0 is a reliable measure across a diverse range of activity types. Methods: Ninety-four participants completed the test and retest measurements within a 2- to 3-week period. A total of 202 activities were included in the analysis, grouped into leisure (LE) 94, productivity (PD) 35, and self-care (SC) 73. Findings: The estimates of test-retest reliability (95% confidence interval CI) for SC, LE, and PD were 0.863 (0.794,0.91), 0.860 (0.793,0.907), and 0.876 (0.771,0.935), respectively, indicating good reliability across the two time points for each of the three categories. The Cronbach's alphas at time point 1 for SC, LE, and PD were 0.744 (0.666, 0.808), 0.711 (0.63, 0.778), and 0.694 (0.517, 0.818), respectively, suggesting acceptable to good internal consistency. Similarly, the estimates of Cronbach's alpha at time point 2 for the three occupational categories were: 0.79 (0.725, 0.842), 0.766 (0.7, 0.82), and 0.775 (0.645, 0.866), respectively, indicating good internal consistency. Conclusion: The findings suggest that ORM 1.0 has test-retest reliability and internal consistency across leisure, productivity, and self-care occupations. The outcomes support the use of ORM 1.0 in clinical practice and research, although further research could strengthen its psychometric properties.
