Abstract
Graphic models can improve understanding of theoretical concepts and the relationship between concepts. This article introduces a model of Commitment to Health Theory, which describes the process of behavior change from action to the maintenance stage of change. Commitment to health means that a new or modified health behavior will be used regardless of socioeconomic factors, race, gender, employment category, and age. Findings were based on three cross-sectional survey studies of approximately 1,085 predominantly manufacturing workers sampled from across the United States. Commitment to Health Theory was used to identify those in the action stage of change with mid-level commitment and predict the likelihood of successfully changing health behavior. Monitoring levels of commitment to health can determine appropriate intervention strategies to assist clients who currently exhibit unhealthy diet and exercise behaviors.
