Prediction of Theory of Planned Behavior on Action Plan and Anticipated Regret of Sport Injury Rehabilitation Adherence

Abstract

The purposes of this study were: (1) to explore the effects of the theory of planned behavior on interpreting sport injury rehabilitation adherence behavior, (2) to examine the added effects of action plan on predicting behavior excluding constructs of the theory of planned behavior, (3) to examine the mediated effects of action plan on the relation between intention and behavior, and (4) to explore the moderated effects of anticipated regret on the mediated effects of action plan on the relation between intention and behavior. Two hundred- and thirty-one injured athletes (aged: 23.6±4.5 years) were participated in healing or rehabilitation programs. After providing the informed consent, all participants were asked to complete a series of inventories, including measures of the theory of planned behavior, action plan, anticipated regret and sport injury rehabilitation adherence scales. The data were analyzed by multiple hierarchical regression analysis. Results of this study indicated that: (1) subjective norm and perceived behavior control except attitude predicted sport injury rehabilitation adherence intention significantly, intention and perceived behavior control predicted behavior significantly, (2) action plan added the effects on predicting behavior, (3) action plan mediated the relation between intention and behavior, and (4) anticipated regret could not moderate the mediated effects of action plan on the relation between intention and behavior. The conclusion of present study was that action plan and anticipated regret extended the theory of planned behavior and validated to the application in the context of sport injury rehabilitation adherence. The implications for practical applications and future directions were also discussed.
