Examining the relationships among concepts of control and exercise attendance

Many researchers in psychology and physical activity have discussed the ove rlap among control constructs in various theories. Skinner (1996) proposed an integrative control framework based on an agent-means-ends distinction t hat offered comparisons among and more explicit measurement of 3 control co nstructs-control, capacity, and strategy beliefs. No study in the exercise domain has yet empirically examined these advantages. This study evaluated Skinner's framework relative to their contribution to predicting exercise a ttendance. A prospective design was used to consider the potential change i n the nature of the relationships. High correlations (range r = .52-.88) at 2 time points in the exercise program suggested overlap among control cons tructs when using Skinner's measurement procedures. Only capacity beliefs a nd behavioral intention were significantly related to exercise attendance ( model R-adjusted(2) = .11 and .16, p = .03 and .01, respectively, at onset and midprogram). The findings do not support Skinner's contentions but are similar to previous findings in the exercise literature.
