Psychological inflexibility and obesity: Mediating factors in psychological health

Abstract

Aim: To explore the relationships between psychological factors, especially experiential avoidance (EA) and psychological inflexibility, and obesity, and to assess their mediating roles in the association between general psychological symptoms and obesity.

Methods: The study employed Pearson correlation analysis and mediation analysis to examine relationships among Body Mass Index (BMI), the Acceptance and Action Questionnaire for Weight-Related Difficulties-Revised (AAQW-R), its subscales, and the General Health Questionnaire (GHQ12). Participants predominantly consisted of females, with a mean age of 39.3 years and an average BMI of 38.5.

Results: Significant correlations were found between BMI, AAQW-R, and GHQ12 (p < 0.05). However, the correlation between BMI and AAQW-R-fc was not significant (p = 0.142). Mediation analysis revealed that AAQW-R fully mediated the relationship between GHQ12 and BMI, indicating a significant role of psychological factors in obesity.

Conclusions: The findings highlight the importance of incorporating psychological elements, such as psychological inflexibility and EA, into obesity interventions. Addressing these factors may enhance the effectiveness of weight control strategies. Future research is encouraged to explore potential biological pathways linking obesity and psychological variables.
