Individual cognitive behavioral therapy and combined family/individual therapy for young adults with Anorexia nervosa: A randomized controlled trial.

Objective: In this study, we evaluate the efficacy of outpatient individual cognitive behavioral therapy for young adults (CBT-YA) and combined family/individual therapy for young adults (FT-YA) for anorexia nervosa (AN). Method: Participants (aged 17-24 years) with AN in Sweden were recruited and assigned to 18 months of CBT-YA or FT-YA. Treatment efficacy was assessed primarily using BMI, presence of diagnosis, and degree of eating-related psychopathology at post-treatment and follow-up. Secondary outcomes included depression and general psychological psychopathology. The trial was registered at http://www.isrctn.com/, ISRCTN (25181390). Results: Seventy-eight participants were randomized, and seventy-four of them received allocated treatment and provided complete data. Clinical outcomes from within groups resulted in significant improvements for both groups. BMI increased from baseline (CBT-YA 16.49; FT-YA 16.54) to post-treatment (CBT-YA 19.61; FT-YA 19.33) with high effect sizes. The rate of weight restoration was 64.9% in the CBT-YA group and 83.8% in the FT-YA group. The rate of recovery was 76% in both groups at post-treatment, and at follow-up, 89% and 81% had recovered in the CBT-YA and FT-YA groups respectively. Conclusions: Outpatient CBT-YA and FT-YA appear to be of benefit to young adults with AN in terms of weight restoration and reduced eating disorder and general psychopathology.

Validation of the Inventory of Interpersonal Problems (IIP-64): a comparison of Swedish female outpatients with anorexia nervosa or bulimia nervosa and controls.

AIM: The aim of the study was to explore the psychometric properties of the Inventory of Interpersonal Problems (IIP-64) and to compare levels of interpersonal distress in Swedish female outpatients with anorexia nervosa or bulimia nervosa with age- and gender-matched controls. METHODS: Totally, 401 participants were included; anorexia nervosa (n = 74), bulimia nervosa (n = 85) and controls (n = 242). All participants completed the IIP-64. The eating disorder (ED) patients also filled out the Eating Disorder Inventory-2/3 (EDI). RESULTS: Internal consistency of IIP-64 was acceptable to high. Principal component analyses with varimax rotation of the IIP-64 subscales confirmed the circumplex structure with two underlying orthogonal dimensions; affiliation and dominance. Significant correlations between EDI-3 composite scales ineffectiveness and interpersonal problems and IIP-64 were found. ED patients reported higher levels of interpersonal distress than controls on all but one subscale (intrusive/needy). CONCLUSIONS: IIP-64 can be considered to have acceptable to good reliability and validity in a Swedish ED sample. IIP-64 can be a useful complement in assessment of interpersonal problems in ED.
