Hypothesis
The study aims to examine the psychometric properties of the Exercise Self-Regulatory Efficacy scale (Ex-SRES) in a larger sample of U.S. Veterans with COPD.
Conclusion
The Ex-SRES is a reliable tool for measuring exercise self-efficacy in older veterans with COPD, but further research is needed to improve its model fit.
Supporting Evidence
- The Ex-SRES demonstrated reliability with a Cronbach’s α of .94.
- Convergent validity was shown with average steps/day (r=.22) and 6-MWT distance (r=.25).
- The confirmatory factor analysis showed an acceptable fit for a unidimensional factor structure.
Takeaway
This study looked at how confident older veterans with COPD feel about exercising, and found a way to measure that confidence.
Methodology
Secondary analyses were performed on baseline assessments of two cohorts of U.S. Veterans with COPD who participated in a physical activity intervention.
Limitations
Room for improved model fit was noted in the confirmatory factor analysis.
Participant Demographics
191 U.S. Veterans with COPD, average age 68, 97% male, 93.2% White.
