Introduction: The complex interplay between psychological factors and clinical manifestations of eating disorders(ED) has been a focus in the literature.The severity of ED symptoms has been consistently associated with various psychological difficulties such as emotion dysregulation[1] and self-esteem issues[2].These factors have been studied across different ED presentations in a transdiagnostic manner.
This study aims to explore the correlation between illness severity parameters and emotion dysregulation and the self-esteem problems among individuals diagnosed with Anorexia Nervosa-Binge Eating/Purging(AN-BEP),Anorexia Nervosa-Restrictive(AN-R),Bulimia Nervosa(BN),and Binge Eating disorder(BED).
Methods: Clinical interviews have been conducted with 133 ED patients of any type who applied to the psychiatry clinic of Istanbul Faculty of Medicine, between 2016-2023.During these interviews, information about the personal history, symptomatology and clinical features was collected.Additionally, Eating Disorder Examination Questionnaire (EDEQ), Difficulties in Emotion Regulation Scale(DERS) and Beck Depression-Anxiety Inventories and Rosenberg Self-Esteem Scale(RSES) were completed.
We compared sociodemographic, clinical features, and scores from clinical scales, using Analysis of Variance(ANOVA) tests among diagnostic groups.We conducted Spearman's Correlation Analysis to examine the correlation between indicators of illness severity and the scores on DERS and RSES for each diagnosis.We employed linear regression analysis to investigate the mediating role of self-esteem in the relationship between emotion dysregulation and ED severity.Separate regression models were constructed to assess the direct and indirect effects of emotion dysregulation mediated by self-esteem.
Results: There were 35 AN-R, 35 AN-BEP, 47 BN and 16 BED patients in our sample.All diagnostic groups are comparable in terms of sociodemographic features and illness durations. However, BED patients significantly older than the other groups(F(3,129)=3.59,p=.016).
These four groups were comparable in terms of illness severity parameters measured by EDEQ, with the exception of EDEQ-restriction subscale, on which AN-R patients scored higher(F(3,129)=3.53,p=.02), and illness duration, for which BED patients had significantly longer duration(F(3,121)=3.04,p=.03).There were no difference among clinical features such as depression-anxiety scores or psychological factors such as DERS and RSES scores.All groups have similar scores on DERS subscales and RSES, AN-R group being an exception with higher scores on DERS-Clarity subscale(F(3,129)=6.37,p=<.001).
Correlation analysis revealed significant positive correlations between EDEQ-Total scores and DERS-Total scores, indicating that higher levels of ED psychopathology were associated with greater emotion dysregulation across all groups(AN-BEP:r=.47**,AN-R:r =.38*,BN:r =.33*).We observed a similar trend between EDEQ-Total and Self-Esteem scores(AN-BEP:r =.59**,AN-R:r =.48**,BN:r =.52**).However, we didn’t observe a similar correlation in BED patients.Additionally, the binge eating and compensatory behaviors did not show a significant correlation with emotion dysregulation or self-esteem.
In the mediator analysis, it was determined that self-esteem fully mediates the relationship between emotion dysregulation and ED severity(EDEQ). The analysis revealed a significant positive effect of emotion dysregulation on self-esteem(β=.49,p=<.001), and a significant positive effect of self-esteem together with emotion dysregulation on ED severity(β=.54,p=<.001). The direct effect of emotion dysregulation on ED severity was significant(β=.27,p=.004); however, when self-esteem was considered as a mediator, this direct effect became non-significant(β=.002,p = .98), indicating a full mediation.
Conclusions: These findings highlight the pivotal role of self-esteem in the pathway between emotion regulation and ED severity and suggest that interventions focusing on enhancing self-esteem may effectively mitigate the impact of emotion dysregulation on ED severity.
