Overeating is a common eating disorder and often leads to obesity and to significant physical, emotional, and social problems often warranting nursing care. Codependency has expanded beyond the chemical dependency field and describes the dysfunctional pattern of behavior of an individual in a relationship with another person or from survival in a dysfunctional family of origin. The psychological and behavioral factors surrounding overeating are noted frequently in the literature but are not emphasized in most overeating treatment programs. Anxiety, depression, anger, and compulsivity are the psychological problems often linked with overeating and codependency. The purpose of this study was to test the Codependency-Overeating Model (COM) by examining the relationship between overeating and codependency, anxiety, depression, anger, and compulsivity. The variables were measured with the Overeating Questionnaire, Codependency Assessment Tool, and Symptom Checklist-90-R. This study used a model-testing correlational design with 567 students recruited from a Mississippi community college. Pearson’s product–moment correlations noted weak correlations between age and anxiety ( r = .12), age and depression ( r = .20), age and compulsivity ( r = .20), codependency and anxiety ( r = .12), and codependency and anger ( r = .16). No significant correlations were noted between overeating and codependency, anxiety, depression, anger, or compulsivity. Although the predictive relationships were not verified in the model, several important ways to minimize limitations in future studies were identified. The development and testing of the COM was the beginning step in pursuing a solid understanding of overeating and codependency and a catalyst for worthwhile future research.
