Abstract
BackgroundAnorexia Nervosa (AN) is a psychiatric illness associated with a number of personality disturbances. However, whether these personality characteristics are related to eating disorder symptomatology or emotion regulation is unclear. The aim of this study was to investigate these relationships.ResultsTwenty-four individuals with AN and 25 age- and premorbid intelligence-matched controls completed the Personality Diagnostic Questionnaire, and scores were correlated with measures of emotionality and negative mood states, and eating disorder symptomatology. AN was associated with increased scores on schizoid, borderline, avoidant, dependent, obsessive compulsive, negativistic and depressive personality dimensions, relative to controls. In AN, eating disorder symptomatology did not significantly correlate with scores on any personality dimension. However, a number of personality characteristics were found to correlate with negative mood states.ConclusionsThe findings suggest that personality disturbances in AN are not related to disorder-specific symptoms, but are related to negative mood states.

In the healthy controls (HC) group, no significant correlations were found between personality scores and Depression Anxiety Stress Scale (DASS) subscales
Summary
Anorexia Nervosa (AN) is a psychiatric illness associated with a number of personality disturbances. Whether these personality characteristics are related to eating disorder symptomatology or emotion regulation is unclear. Personality disorders are related to poor emotion processing and negative mood states [12, 13], which are reported in AN [14, 15]. It is unclear whether personality disturbances in AN interact with eating disorder symptomatology, or whether they relate to difficulties in emotion regulation. Given the lack of current treatment options for AN [16], this research is warranted to determine which personality variables are associated with mood regulation or eating disorder symptomatology to help guide the development of more tailored and effective interventions for AN
