Abstract

This study examined the validity and reliability of translated scales to measure physical activity (PA) related self-efficacy, self-regulations and social support in Hong Kong Chinese working adults. Subjects (N = 230, aged 19-63 years) were recruited by convenient sampling. To assess validity of the scales, both factorial validity and criterion validity were evaluated. The factorial validity was conducted by Confirmatory Factor Analyses (CFA) while criterion validity was assessed by correlating measured constructs with self-reported physical activity. Cronbach‟s alaph was computed to evaluate internal consistency and intraclass correlation coefficient was evaluated to check scales test-retest reliability. The CFA results supported the one-factor structure of the scales. All physical activity correlates were significant (p < 0.01) associated with self-reported physical activity. All the scales demonstrated acceptable internal consistency and test-retest reliability. The result provides psychometric support for using the scales to measure PA correlates among Hong Kong working adults.
