Models of human social behavior and their application to health psychology

Abstract

Theoretical models popular in the health domain differ in level of generality. Some were developed to deal with any human social behavior and then applied to health psychology, others were specifically designed to deal with health-related issues. Content-specific theories, such as the health-belief model and the perceptual-cognitive approach, outline in detail factors relevant for our understanding of health-related beliefs and actions. In contrast, it is only in the course of empirical research that content-free models, such as social cognitive theory and the theory of planned behavior, obtain the specific information required for understanding. Their advantage lies in their applicability across behavioral domains. Whether content-specific or content-free, the major utility of models developed to date has been to organize and communicate knowledge about health-related behavior. Few profound insights have as yet resulted from their application, with the possible exception of the recognition that self-regulation, and especially self-efficacy, plays a major role in all aspects of health, illness, and recovery.
