A Worksite Intervention to Enhance Social Cognitive Theory Constructs to Promote Exercise Adherence

Abstract

There were specific limitations, and the results should be interpreted cautiously. The sample size was relatively small, although similar to other exercise intervention research reviewed by Dishman. Another limitation of the sample was no random assignment to treatment or comparison group. The results apply only to the subjects who volunteered for this study. The measure of outcome-expectancy value is the most vulnerable of those used to measure outcome expectations and outcome expectancies. It is possible that the results of the study would be substantially altered if a better measure were available. The data were collected through self-administered questionnaires. It was assumed the subjects would provide accurate information, but reliance on self-reported data introduces potential sources of error.
