Abstract
Background and purpose: Many physically capable stroke survivors are insufficiently active, with low self-efficacy considered an important contributor. However, validity and reliability of self-efficacy measures in stroke survivors have not been established. This research aims to evaluate the test-retest reliability and construct validity of 3 self-efficacy measures: Self-Efficacy for Exercise Scale (SEE), Spinal Cord Injury Exercise Self-Efficacy Scale (SCI-ESES), and Participation Strategies Self-Efficacy Scale (PS-SES).
Methods: A repeated measures study with community-dwelling, independently mobile adult stroke survivors (n = 51, mean age 74 years, 45% female, median 22 months poststroke) was completed. Test-retest reliability was assessed using intraclass correlation coefficients and Bland-Altman analyses. Construct validity was assessed using 8 pre-determined hypotheses concerning physical activity level (subjective and objective), comorbidities, work and volunteering, and measures of function.
Results: Retest reliability was established for the SEE (intraclass correlation coefficient, ICC = 0.77) and PS-SES (ICC = 0.78) but not for the SCI-ESES (ICC = 0.68). Bland-Altman analysis showed participants consistently scored higher on the second test for all measures. The SEE achieved construct validity by meeting 75% of hypotheses, whereas the PS-SES and SCI-ESES did not. Self-efficacy was positively related to steps/day, functional capacity, self-reported activity levels, and work or volunteering participation.
Discussion and conclusions: The SEE was found to be the most appropriate tool to measure exercise self-efficacy in independently mobile chronic stroke survivors in terms of retest reliability and validity.

期刊介绍：
The Journal of Neurologic Physical Therapy (JNPT) is an indexed resource for dissemination of research-based evidence related to neurologic physical therapy intervention. High standards of quality are maintained through a rigorous, double-blinded, peer-review process and adherence to standards recommended by the International Committee of Medical Journal Editors. With an international editorial board made up of preeminent researchers and clinicians, JNPT publishes articles of global relevance for examination, evaluation, prognosis, intervention, and outcomes for individuals with movement deficits due to neurologic conditions. Through systematic reviews, research articles, case studies, and clinical perspectives, JNPT promotes the integration of evidence into theory, education, research, and practice of neurologic physical therapy, spanning the continuum from pathophysiology to societal participation.
