OBJECTIVE: To develop a valid stroke-specific tool, named the Participation
Measurement Scale (PM-Scale), for the measurement of participation after stroke.
DESIGN: Observational study and questionnaire development. SETTING: Outpatient
rehabilitation centers. PARTICIPANTS: Patients with stroke (N=276; mean age,
58.5+/-11.1y; 57% men). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES:
Participants 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 depression, and the modified Rankin
Scale was used to categorize the severity of disability on the basis of
observation. RESULTS: After successive Rasch analyses using 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, .93). The test-retest
reliability of item difficulty hierarchy (r=.96; P<.001) and patient location
(r=.99; P<.001) were excellent. This patient-based scale covers all 9
International Classification of Functioning, Disability and Health domains of
participation. CONCLUSIONS: The PM-Scale has good psychometric qualities and
provides accurate measures of participation in patients with stroke in Africa.
