ABSTRACT

This study proposes and tests a theory driven model: the psychological health, behavior and body weight (PBBW) model. The model hypothesizes an indirect relationship between psychological health and body weight, mediated by health behaviors. Correctional employees (N = 317) completed physical assessments and self-report surveys that measured body mass index (BMI), perceived stress, psychological health (overall mood and depressive symptoms), and health behavior (as indicated by reported diet and exercise quality). The authors used structural equation modeling to evaluate the relationships between variables and test the model. Results supported the PBBW model, and findings suggested that psychological health and stress affected body weight. Furthermore the effect of psychological health on body weight was mediated by health behaviors.
