ABSTRACT
Obesity remains a medical issue of great concern. Behavioural methods attempting to induce weight loss have largely failed because of a minimal understanding of stress- and depression-associated psychosocial correlates. This study extended research into the effects of exercise on weight loss through psychological pathways to improve treatments. Women with obesity (N = 108), participating in an original theory-driven cognitive-behavioural treatment within community-based health promotion centres, were evaluated over 24 months. Their mean scores on anxiety, depression, and anger at baseline were significantly higher than normative data from a general sample of United States women. Three serial mediation models were specified assessing mediation of the significant exerciseâdietary change relationship. These yielded two significant paths changes in exerciseâanxietyâanxiety-associated emotional eatingâself-efficacyâdiet, and changes in exerciseâdepressionâdepression-associated emotional eatingâself-efficacyâdiet; and one non-significant path changes in exerciseâangerâanger-associated emotional eatingâself-efficacyâdiet. In a subsequent moderated moderation model, change in eating-related self-regulation moderated the relationship between changes in anxiety and anxiety-associated emotional eating, where exercise-associated self-regulation moderated effects from eating-related self-regulation. Dietary improvement was significantly related to weight loss over 6 (ß = -0.40), 12 (ß = -0.42), and 24 (ß = -0.33) months. Findings indicated an increased treatment focus on the completion of moderate amounts of exercise for weight loss and, following that, attention to improvements in anxiety, depression, anxiety- and depression-associated emotional eating, self-efficacy for controlled eating, and the transfer of exercise-related self-regulation to eating-related self-regulation. Given the scope of the obesity problem, extensions of this research within field settings are warranted to accelerate application opportunities.
