Akrasia, health behavior, relapse, and reversal theory

Philosophical explanations of the phenomenon of akrasia have been used in this article to characterize some of the difficulties involved in successful behavior change. The theory of psychological reversals provides a framework for understanding various types of akratic behavior. In addition, empirical research on the temptations of persons trying to quit smoking has supported hypotheses generated by the theory. The theory suggests that resisting the temptation to engage in akratic behavior is a complex phenomenon. Different strategies are needed in different types of metamotivational states. Reversal theory provides a coherent system for understanding and predicting akratic behavior. It suggests possible interventions that would improve the probability of circumventing akrasia and that would improve behavior change efforts of nurses engaged in health-promotion and disease-prevention activities.
