Abstract
Background: Obesity is a growing epidemic with non-surgical/non-pharmacological interventions having only nominal and transient effects on excess weight. Those persistent shortcomings are associated with minimal understandings of impacts of treatment-associated changes in psychological variables and their relationships. Women of lower incomes have high rates of obesity and might have increased difficulties accessing evidence-based programs.
Methods: Women with obesity of lower- to lower-middle incomes participated in 6-month community-based treatments in the United States emphasizing either self-regulatory skills development (behavioral methods group: n = 63) or typical education in exercise and healthy dietary practices (education group: n = 48).
Results: There were significant 6-month improvements in self-regulation, self-efficacy, mood, physical activity/exercise, dietary behaviors, and weight in both groups. All improvements were significantly greater in the behavioral group. Based on the incorporation of multiple behavioral theories, separate multiple regression models were fit for prediction of the weight-loss behavior changes. Stepwise entry of changes in self-regulation, self-efficacy, and mood each significantly contributed to the explained variance in physical activity/exercise change. Change in self-efficacy was most relevant in the prediction of change in dietary behaviors. Change in physical activity/exercise was significantly related to change in dietary behaviors; however, a regression analysis indicated that only physical activity/exercise change was a significant independent contributor to the overall accounted-for variance in lost weight.
Conclusion: By incorporating key tenets of social cognitive theory, self-efficacy theory, self-regulation theory, coaction theory, and the mood-behavior model in an additive manner, suggestions and emphases for addressing psychological variables for improved weight-loss behaviors within scalable obesity treatments were advanced.
