Emotional dysregulation and attachment dimensions in female patients with bulimia nervosa.

BACKGROUND The aim of this study was to examine whether there is a difference in the dimensions of attachment and difference in emotional regulation between the group of female patients suffering from bulimia nervosa (BN) and the control group. We also wanted to examine whether emotional regulation has a mediating role in the relationship between dimensions of attachment and severity of BN symptoms. SUBJECTS AND METHODS The study included a total of 100 female participants from 15 to 25 years of age (M=20.40, SD=3.26). The clinical group consisted of 50 patients suffering from BN, and the control group consisted of 50 healthy female subjects. RESULTS Female patients suffering from BN achieved higher scores in the dimensions of anxiety (t98=-5.12, p=0.00) and avoidance (t98=-4.30, p=0.00). Dimension of attachment related anxiety (β=0.44, p=0.00) proved to be a statistically significant predictor of BN symptoms. Subjects of the clinical group also achieved significantly higher (t98=7.41, p=0.00) emotional dysregulation than participants of the control group. We also found that the mediation effect of emotional regulation on the association between anxiety and BN symptoms was statistically significant (z'=4.43, p=0.00). CONCLUSIONS Patients suffering from BN showed significantly higher levels of attachment related anxiety and avoidance as well as significantly higher level of difficulties in emotional regulation than healthy controls. Attachment anxiety proved to be a significant predictor of symptoms BN, suggesting that the attachment related anxiety is stronger correlate of BN symptoms than avoidance, and may represent a risk factor for more severe BN symptoms. It was also found that the relationship between attachment related anxiety and BN symptoms were mediated by emotional regulation.
