Presenting a structural model of the effectiveness of cognitive-based intervention on fat and cortisol profiles with the mediating effect of brain-behavioral systems, cognitive flexibility in overweight people with high stress

Introduction: The present study aimed to present and investigate the structural model of the effectiveness of the cognitive-based intervention on cortisol and lipid profiles with the mediating effect of cognitive flexibility and behavioral brain systems in overweight people with high stress. Method: The research design was experimental with a control group and pre-test-post-test and follow-up design. The statistical population of this research was all ۱۹۰ people referred to the cosmetic surgery clinic in ۲۰۲۳. The research sample consisted of ۳۰ people (۱۵ for the experimental group and ۱۵ for the control group) selected through the purposeful sampling method and according to the research inclusion and exclusion criteria. The respondents answered the Multidimensional Self-Body Relationship Questionnaire (Kash et al., ۱۹۸۷), the Behavioral Activation / Inhibition Systems Scale (Carver & White, ۱۹۹۴), and Connor & Davidson’s Flexibility Questionnaire (۲۰۰۳). Results: The results of univariate covariance analysis showed a significant difference between the two experimental and control groups in the variables of brain-behavioral systems (F = ۳.۸۲۴, P = ۰.۰۳۵) and cognitive flexibility (F = ۴.۹۵۸, P= ۰.۰۳۲). Also, the effectiveness of the cognitive intervention on cortisol was ۰.۷۰. This means that ۷۹% of the changes obtained in the post-test scores of the experimental group were due to the intervention. Conclusion: We can conclude that stress leads to an increase in overweight and a reduction in an individual's flexibility and positive attitude toward body image. Therefore, training and treating overweight people to manage their stress correctly is necessary.
