title: Contribution of Interpersonal Problems to Eating Disorder Psychopathology via Negative Affect in Treatment-seeking Men and Women: Testing the Validity of the Interpersonal Model in an Understudied Population.
abstract: Research on the psychosocial correlates and theoretical frameworks of men presenting with eating disorders (ED) psychopathology is limited. This study compared treatment-seeking men and women in terms of their levels of interpersonal functioning (affiliation and dominance), regulation of negative emotions (negative affect and instability) and ED psychopathology. The study also investigated the validity of the interpersonal model of ED in men. Results from the cross-sectional data of 388 participants (137 men and 251 women) demonstrated that the structural models fit and that paths were invariant across men and women. There were significant indirect effects of interpersonal functioning on ED psychopathology, mediated through negative affect and instability, for both men and women. Negative affect and instability partially explain the relationship between interpersonal problems and ED psychopathology in treatment-seeking men and women. Current findings highlight the need to evaluate the validity of the model using longitudinal designs to test whether men and women are likely to benefit equally from interpersonal therapies for ED.

  CONCLUSIONS
  Negative affect and instability mediated the relationship between interpersonal problems and eating disorder psychopathology for treatment-seeking men and women. There were no gender differences between levels of negative affect, emotional instability and interpersonal dysfunction, but women reported slightly higher eating concerns than men. Interpersonal model is a framework that is applicable to understanding and potentially treating men with eating disorders.
