ObjectiveTo 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).DesignMulticenter observational study.SettingOutpatient rehabilitation programs.ParticipantsIn total, 262 rehabilitation outpatients participated in the study, of whom 202 participated in the test-retest study, and a separate 60 participated in the two modes of administration study.InterventionsNot applicable.Main outcome measureThe PM-3D4D includes 19 items measuring participation in productivity, social, and community domains across four dimensions: diversity, frequency, desire for change, and perceived difficulty.ResultsThe test-retest reliability was good across domains and dimensions (intraclass correlation coefficients (ICCs)=0.76∼0.96), and in neurological and non-neurological groups. The test-retest reliability was also mostly good at the item-level. Strong concordance was found between the two administration modes (ICCs=0.96∼1.00).ConclusionsStudy results lend support to the use of the PM-3D4D to reliably assess participation in rehabilitation patients. The strong concordance between the two administration modes suggests the potential use of the instrument in population-based research.
