Psychological Mechanisms of Interactions between Improvements in Exercise and Healthy Eating Behaviors (Coaction) within a Community-Based Obesity Treatment Setting.
Coaction refers to positive change in one behavior increasing the probability of positive change in a second behavior. Because mechanisms of coaction have not been well studied, and its improved comprehension might optimize architectures of multi-component behavioral obesity interventions, this research aimed to incorporate theory to assess whether treatment-associated changes in self-regulation and self-efficacy sequentially mediate an association between increased exercise and improved eating. Women with obesity (Mean age = 47.9 years) were randomized into community-based obesity treatments with either a self-regulatory skills emphasis (n = 47), or a more equal focus on education and self-management (n = 52). Each treatment aimed to foster weight loss and reductions in health risks. Over 6 months, there were significant improvements in exercise outputs, fruit/vegetable consumption, sweets intake, exercise- and eating-related self-regulation, and exercise- and eating-related self-efficacy that were significantly greater in the high self-regulation group. Using aggregated data, bivariate relationships between changes in exercise, and fruit/vegetable and sweets intake, were significant. Serial mediation analyses indicated that increased exercise outputs were associated with improved eating through the sequential relationships of eating-related self-regulation and self-efficacy, while improved eating was associated with increased exercise more directly through exercise-related self-regulation. Moderation analyses demonstrated stronger associations in the high self-regulation group for relationships between changes in exercise and eating-related self-regulation and self-efficacy only. Results initiated analyses into mechanisms of coaction among exercise and eating behaviors, and reinforced the value of self-regulatory skills enhancement directly and through its effects on domain-specific self-efficacy in behavioral obesity treatments.
期刊介绍:
Behavioral Medicine is a multidisciplinary peer-reviewed journal, which fosters and promotes the exchange of knowledge and the advancement of theory in the field of behavioral medicine, including but not limited to understandings of disease prevention, health promotion, health disparities, identification of health risk factors, and interventions designed to reduce health risks, ameliorate health disparities, enhancing all aspects of health. The journal seeks to advance knowledge and theory in these domains in all segments of the population and across the lifespan, in local, national, and global contexts, and with an emphasis on the synergies that exist between biological, psychological, psychosocial, and structural factors as they related to these areas of study and across health states.
Behavioral Medicine publishes original empirical studies (experimental and observational research studies, quantitative and qualitative studies, evaluation studies) as well as clinical/case studies. The journal also publishes review articles, which provide systematic evaluations of the literature and propose alternative and innovative theoretical paradigms, as well as brief reports and responses to articles previously published in Behavioral Medicine.
