Evaluation of Eating Attitudes, Anger and Impulsivity in Atypical and Non-Atypical Depression and Assessment of Comorbidity of Binge Eating.

Abstract

Although there have been studies investigating emotional eating, impulsivity and anger, the relationship between differentiated eating attitudes, impulsivity and anger in atypical depression has not yet been studied. Therefore, the aim of this study was to evaluate eating attitudes, impulsivity and anger in participants with atypical and non-atypical depression and to compare their behaviours with those of the control group. Binge eating comorbidity was also investigated. The relationship between eating attitudes, impulsivity and anger was explored and the factors contributing to disordered eating attitudes were analysed. The participants were divided into three groups; 56 with atypical depression, 36 with non-atypical depression and 32 healthy controls for comparison. Clinical assessment was carried out using the Structured Clinical Interview for DSM-IV Axis I Disorders, Barratt Impulsiveness Scale, Multidimensional Anger Scale, Eating Attitude Test, and Hamilton Depression Scale. Deteriorated eating attitudes, increased anger symptoms and motor impulsivity were observed more in participants with atypical depression compared with participants with non-atypical depression. The frequency of binge eating was statistically significantly higher in participants with atypical depression (50%) than in participants with non-atypical depression (8%). A positive relationship was identified between deteriorated eating attitude, anger, and impulsivity. Behaving anxiously as a reaction to anger was found to be the significant predictor of disordered eating attitudes in participants with depression. The percentage of the variance explained by anxious behavior in disordered eating attitudes was 7%. Participants in the atypical and non-atypical depression groups can be differentiated from each other based on their eating attitudes, anger symptoms, motor impulsivity and binge eating frequency.
