Purpose: To translate and assess the reliability and validity of a Chinese version of the Physical Activity Scale for the Elderly (PASE).
Methods: Participants included Chinese individuals >65 living in the community or assistive living facilities. At baseline, 73 subjects completed the translated PASE, and Chinese versions of three other scales to evaluate validity; the Timed-Up and Go (TUG), the Older American Resources Services Activities of Daily Living (OARS ADL), and the Activities Balance Confidence Scale (ABC). At follow-up, 66 subjects completed the PASE and a questionnaire to determine if there were any changes in health over the retest period.
Results: The mean baseline PASE-C score was 76.0 (±49.1) at baseline and 78.33 (±50.27) at follow up. Correlations between the PASE-C and other variables were: age r = -0.51; TUG r = -0.52; OARS ADL r = 0.56 and ABC score r = 0.62. The retest reliability was ICC = 0.79 (95% confidence interval 0.68-0.86).
Conclusion: Our results indicate that the PASE-C has acceptable reliability and there is support for validity in the older Chinese population.
