ObjectiveTo develop a valid stroke-specific tool for the measurement of participation in Africa, named the Participation Measurement Scale (PM-Scale).DesignObservational study and questionnaire development.SettingOutpatient Rehabilitation centers.ParticipantsStroke patients (N = 276); mean age ± standard deviation of 58.5 ± 11.1 years; 57% male.InterventionNot applicable.Main Outcome MeasuresParticipants completed a 100-item experimental questionnaire of the PM-Scale. Items were scored as "not at all", "weakly" or "strongly". The Hospital Anxiety and Depression Scale was used to evaluate the depression and the modified Rankin Scale was used to categorize the severity of disability on the basis of observation.ResultsAfter successive Rasch analyses using RUMM2030 software package under unrestricted partial-credit parameterization, a valid, unidimensional and linear 22-item scale for the measurement of participation was constructed. All 22 items fulfilled the measurement requirements of overall and individual item and person fits, category discrimination, invariance, and local response independence. The PM-Scale showed good internal consistency (person separation index = 0.93). The test–retest reliability of item difficulty hierarchy (r = 0.96, p <0.001) and patient location (r = 0.99, p <0.001) were excellent. This patient-based scale covers all nine ICF domains of participation.ConclusionsThe PM-Scale has good psychometric qualities and provides accurate measures of participation in patients with stroke in Africa.
