  • Personality as predictor of outcome in internet-based treatment of bulimic eating disorders
  • 2020

    • Internet-based cognitive behavioral therapy (ICBT) for bulimic eating disorders has demonstrated clinical utility and cost efficiency, but is associated with low patient preference, low credibility, sizeable dropout and only moderate symptom reduction. To improve outcome it is imperative to learn more about who might benefit from internet-based interventions. To do this, the current study investigated the Five Factor Model of personality as predictor of outcome in patients with full or sub-threshold bulimia nervosa (n = 109). Patients in a randomized controlled trial of ICBT were assessed prior to and at the end of treatment. Patients showed significant symptom reduction over time (Cohen's d = 1.0, p < .001). Remission as well as overall symptom reduction was positively predicted by Openness to Experience and Conscientiousness. Binge eating cessation specifically, was positively predicted by Extraversion. The study supports the use of personality assessment for patient selection and outcome optimization in internet-based treatment of bulimic eating disorders.

  • Individual cognitive behavioral therapy and combined family/individual therapy for young adults with Anorexia nervosa : A randomized controlled trial
  • 2020
  • Ingår i: Psychotherapy Research. - : Routledge. - 1050-3307 .- 1468-4381. ; 30:8, s. 1011-1025

    • 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.

  • Genetic and environmental contributions to diagnostic fluctuation in anorexia nervosa and bulimia nervosa
  • 2021
  • Ingår i: Psychological Medicine. - : Cambridge University Press. - 0033-2917 .- 1469-8978. ; 51:1, s. 62-69
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Anorexia nervosa and bulimia nervosa are two severe eating disorders associated with high premature mortality, suicidal risk and serious medical complications. Transition between anorexia nervosa and bulimia nervosa over the illness course and familial co-aggregation of the two eating disorders imply aetiological overlap. However, genetic and environmental liabilities to the overlap are poorly understood. Quantitative genetic research using clinical diagnosis is needed.METHODS: We acquired a clinical diagnosis of anorexia nervosa (prevalence = 0.90%) and bulimia nervosa (prevalence = 0.48%) in a large population-based sample (N = 782 938) of randomly selected full-sisters and maternal half-sisters born in Sweden between 1970 and 2005. Structural equation modelling was applied to quantify heritability of clinically diagnosed anorexia nervosa and bulimia nervosa and the contributions of genetic and environmental effects on their overlap.RESULTS: The heritability of clinically diagnosed anorexia nervosa and bulimia nervosa was estimated at 43% [95% confidence interval (CI) (36-50%)] and 41% (31-52%), respectively, in the study population, with the remaining variance explained by variance in unique environmental effects. We found statistically significant genetic [0.66, 95% CI (0.49-0.82)] and unique environmental correlations [0.55 (0.43-0.66)] between the two clinically diagnosed eating disorders; and their overlap was about equally explained by genetic and unique environmental effects [co-heritability 47% (35-58%)].CONCLUSIONS: Our study supports shared mechanisms for anorexia nervosa and bulimia nervosa and extends the literature from self-reported behavioural measures to clinical diagnosis. The findings encourage future molecular genetic research on both eating disorders and emphasize clinical vigilance for symptom fluctuation between them.
