Abstract
Introduction : The Environmental Support for Physical Activity Questionnaire (ESPA)was developed for older people in western country. However, due todifferent geographical features and lifestyle between countries,modification to the ESPA has been made to create “the ThaiEnvironmental Support for Physical Activity (TESPA)”.Objective : To verify the reliability and validity of TESPA.Settings : Twelve communities in six provinces of ThailandResearch design : Cross-sectional design.Patients : Three hundred and twenty older people were randomly selected usingmultistage random sampling.Methods : The content validity was determined by three geriatric experts.The construct validity was approached by structural equation modelingand known-group method. The reliability was analyzed using alphacoefficient.Results : The content validity index of TESPA was 0.92. The construct validityillustrated that the measurement model explained 61% of the varianceof TESPA. The internal consistency and the test-retest reliability ofthe scale were 0.73 and 0.76.Conclusion : TESPA is reliable, and able to successfully assess the physicalenvironment for elderly in Thai culture.
