Mental Health and Substance Abuse Services of the Berkshires, Pittsfield, Massachusetts, USA Objective: To determine the validity, repeatability and stability of the Motor Readiness Questionnaire for Stroke (MRQS). Subjects: One hundred and eighty-seven stroke patients (160 men; 143 white; mean age=57.59±8.8; mean time since stroke=10.19±7.3 months) at a rehabilitation hospital in the Midwestern United States. Design: Prospective survey, in which the MRQS was administered to each patient once. The MRQS was also administered to 25 subjects twice to measure test-retest reliability. Main outcome measures: The MRQS, a transtheoretical model-based, 23-item self-report survey was administered to examine reliability (internal consistency and stability), validity (concurrent) and factor structure. Results: The MRQS showed good reliability for its component scales and total score, and the previously identified MRQS factor structure was confirmed. Stability and concurrent validity were also high. Conclusions: The MRQS appears to adequately capture stroke patients motivational readiness and has ability to discriminate between individuals in various stages of readiness. MRQS scores appear to be repeatable over time. However, more research is needed before the MRQS is used.
