Hypothesis
The study aims to test the psychometric properties of the Korean version of the index of self-regulation (KISR) for physical activity in older Korean Americans.
Conclusion
The KISR is a reliable and valid measure to assess the level of self-regulation for physical activity in older Korean Americans.
Supporting Evidence
- The KISR showed high internal consistency with Cronbach's alphas of .94 and .95.
- Test-retest reliability was moderate-to-high at .67.
- Significant positive correlations were found between self-regulation and self-efficacy (R = .35, P = .003).
- Construct validity was supported by factor analysis explaining 89% of the variance.
Takeaway
This study created a questionnaire to help older Korean Americans understand how well they can manage their physical activity. It found that the questionnaire works well.
Methodology
The KISR was administered to older Korean Americans at baseline and 12 weeks later to assess reliability and validity.
Potential Biases
Potential bias due to self-reported measures and the specific demographic of participants.
Limitations
The study used a convenience sample from specific ethnic churches, which may limit generalizability.
Participant Demographics
Participants were community-dwelling older Korean Americans, average age 72, predominantly female (74%), and mostly married (60%).
