However, PA participation in this population is abysmal. The purpose of this study was to test a social cognitive theory (SCT) model of (a) PA behavior and (b) PA and QOL in a sample of breast cancer survivors (N = 370; M age = 56. 5) over a 6-month period. Participants wore an accelerometer and completed measures of PA, self-efficacy, goals, outcome expectations, fatigue, social support, health status, and global QOL. It was hypothesized that (a) self-efficacy directly and indirectly influences PA through goals, social support, fatigue, and outcome expectations, and (b) PA indirectly influences global QOL through self-efficacy and health status. Relationships were examined using panel analysis within a covariance modeling framework. Model A provided a good model-data fit (χ2 = 577.98, df = 261, p = 0.00; CFI= 0.95; RMSEA = 0.06; SRMR = 0.06). At baseline, self-efficacy directly and indirectly, via goals, influenced PA. The same results were found for changes in these constructs. Model B was a good fit to the data (χ2 = 278.70, df = 127, p = 0.00; CFI= 0.95; RMSEA= 0.07; SRMR= 0.06). PA indirectly influenced global QOL via self-efficacy and health status at baseline and the same relationships were found for changes in model constructs. These results support the use of SCT to understand PA behavior and QOL in breast cancer survivors. Recommendations are made relative to future examinations of these models.","Made available in DSpace on 2011-08-26T15:34:02Z (GMT).
