Background: Self-esteem and depression contribute to poor outcomes, including lower quality of life, in eating disorders. However, limited research has examined whether other variables may affect how these variables influence one another over time. Metacognition is a previously unexplored determinant that may impact relationships between self-esteem, depression, and quality of life in eating disorders.
Aim: This study sought to examine metacognitive self-reflectivity and mastery as moderators of relationships between self-esteem, depression, and quality of life and to determine if these relationships differed between participants with anorexia and bulimia.
Methods: Participants with anorexia (n = 40) and bulimia (n = 40) were recruited from outpatient clinics. Participants were assessed on metacognitive ability and completed self-report measures of depression, self-esteem, and quality of life.
Results: Results indicated that metacognitive self-reflectivity moderated the relationship between self-esteem, depression, and quality of life in anorexia such that for those with higher levels of self-reflectivity, lower self-esteem and higher depression were associated with lower quality of life. These relationships were not significant when self-reflectivity was low. In contrast, in anorexia and bulimia groups, metacognitive mastery moderated the relationships between self-esteem, depression, and quality of life such that for those with lower levels of mastery, lower self-esteem and higher depression were associated with lower quality of life. These relationships were not significant when mastery was high.
Conclusion: Metacognitive self-reflectivity and mastery serve in paradoxical moderating roles in relationships between self-esteem, depression, and quality of life for people with anorexia and bulimia. These findings introduce options for future work and have important clinical implications.
