Objective: To evaluate the test-retest reliability and the concordance between the interviewer-administered version and the self-administered version of a newly developed participation measure, Participation Measure-3 Domains, 4 Dimensions (PM-3D4D). Design: Multicenter observational study. Setting: Outpatient rehabilitation programs. Participants: Rehabilitation outpatients (N=262) participated in the study, including those (n=202) who participated in the test-retest study and those (n=60) who participated in the 2 modes of the administration study. Interventions: Not applicable. Main Outcome Measures: The PM-3D4D includes 19 items measuring participation in productivity, social, and community domains across 4 dimensions: diversity of participation, frequency of participation, desire for change, and difficulty in participation. Results: The test-retest reliability was good across domains and dimensions (intraclass correlation coefficients, .76-.96) as well as in neurological and nonneurological groups. The test-retest reliability was also mostly good at the item level. A high concordance was found between the 2 administration modes (intraclass correlation coefficients, 0.96-1.00). Conclusions: The study results lend support to the use of the PM-3D4D to reliably assess participation of rehabilitation patients. The high concordance between the 2 administration modes suggests the potential use of the instrument in population-based research.
