Purpose: The purpose of this study was to evaluate the psychometric characteristics of the Korean version of Community Healthy Activities Model Program for Seniors Questionnaire (K-CHAMPS).
Methods: A convenience sample of 423 older Koreans were interviewed twice (two-week interval). Test-retest reliability, content validity, and construct validity were assessed using the SPSS program.
Results: The 41 item K-CHAMPS was developed through linguistic validation and cultural adaptation. Test-retest reliability was .96 for all listed physical activities and .95 for the least moderate intensity physical activities. Factor analysis resulted in 10 factors; playing tennis, swimming, strength training, light activity, outdoor gardening, general exercises, vigorous activity, moderate activity, playing golf, and dance. These 10 factors explained 60.1% of total variance and construct validity was confirmed. The caloric expenditure per week was 2,485±2,363.4) for all listed activities and 1,252±1,904.7 for the least moderate intensity activities. The frequency per week was 15.5±11.9 for all listed activities and 4.8±6.7 for the least moderate intensity activities. Men were more active than women.
Conclusion: Results indicate that K-CHAMPS is valid and reliable to measure physical activity. Interventions promoting increased activity through the use of existing community resources may help increase physical activity in older Koreans.
