Theories are needed to explain and predict health behavior, as well as for the design and evaluation of interventions. Although there has been a history of developing, testing, applying, and refining health behavior theories, debates and limitations in evidence exist: The component of theories which, for example, predicts change should be better elaborated so that we can more easily understand what actually drives behavior change. Theories need to be empirically testable in two ways. Theories need to specify a set of changeable predictors to describe, explain, and predict behavior change, and they should enable us to design an effective intervention that produces exactly those changes in behavior that are predicted by the relevant theory. To make this possible, theories need to be specified in such a way that they can be rigorously tested and falsified. Moreover, for the design of theory-based interventions it must be possible to derive change techniques from the theory and to use them to generate changes in behavior. Based on eight state-of-the-science articles that make conceptual and empirical contributions to the current debate on health behavior theories, various approaches are discussed to gain further insights into explaining and changing health behaviors and the iterative process of theory development. 相似文献

The purpose of the study was to test the Social Cognitive Theory (SCT; Bandura, 2004 ) for explaining physical activity (PA) in a large population sample of adults with type 1 or type 2 diabetes. Study objectives: (1) test the fit of the SCT structure in the total sample, and the diabetes sub-types; (2) determine the SCT structural invariance between the type 1 and type 2 groups; and (3) report explained variance and compare strength of association for the SCT constructs in predicting PA for both type 1 and type 2 groups. In all, 2,311 individuals with type 1 or type 2 diabetes were assessed on their self-efficacy, outcome expectancies, impediments, social support, goals, and physical activity at baseline and 1,717 (74.5%) completed these assessments again at 6 months. Multi-group Structural Equation Modeling was conducted. The findings provide evidence for the utility of the SCT in the diabetes samples. The SCT fits individuals with type 1 and type 2 diabetes except for SCT impediments, which appear to be obstructing goal-setting in individuals with type 2 diabetes only. Promotion of health behavior should target self-efficacy to set goals and change behavior. Outcome expectancies and social support are also important factors for setting goals and behavior performance. 相似文献
