ABSTRACT

Objective:
To examine psychiatric comorbidity and factors that influence the outcome of bulimia nervosa (BN) in the general population.

Method:
Women from the nationwide birth cohorts of Finnish twins were screened for lifetime BN (N = 59) by using questionnaires and the Structured Clinical Interview for DSM-IV. We assessed psychiatric comorbidity and other prognostic factors.

Results:
Among women with lifetime BN, the following were more common than among unaffected women: current major depressive disorder (p = 0.004), lifetime major depressive disorder (p = 0.00001) and heavy drinking (p = 0.01). Decreased likelihood of recovery was associated with a history of lifetime major depressive disorder (hazard ratio (HR) 0.44, 95% confidence interval (CI) 0.23-0.84) and high drive for thinness at time of assessment (HR 0.96, 95% CI 0.93-0.99).

Discussion:
Heavy drinking and depression present challenges for many women with BN. Major depressive disorder emerged as the only statistically significant prognostic factor of BN in this nationwide cohort; high drive for thinness was characteristic of the persistently ill.

    ABSTRACT: Bulimia nervosa (BN) treatment studies consistently observe that substantial reductions in purging frequency after four weeks of treatment predict outcome. Although baseline levels of other variables have been compared to change in purging, measures of early change in other domains have not been examined. This study aimed to compare percentage change in purging, depression, and cognitive eating disorder (ED) symptoms for associations with BN remission post-treatment and at six months follow-up. Data from N = 43 patients with BN in a clinical trial comparing the broad and focused versions of enhanced cognitive behavior therapy (CBT-E; Fairburn, 2008) were utilized. Measures included self-reported purging frequency, Beck Depression Inventory (BDI) score, and a mean of items from the Eating Disorder Inventory Body Dissatisfaction and Drive for Thinness subscales. Results indicated that both percentage change in purging frequency and percentage change in BDI score at week four/session eight were significantly associated with remission at termination. The optimal cutoffs for purging change and BDI score change were 65% decrease and 25% decrease respectively. Only change in BDI score at week four significantly predicted remission at six-month follow-up. These data suggest that change in depressive symptoms may be as important as ED symptom change to predict outcome in some groups.

    ABSTRACT: The aim of this naturalistic study was to identify pretreatment predictors of response to cognitive behaviour therapy in treatment-seeking patients with binge eating disorder (BED; N = 304). Furthermore, we examined end-of-treatment factors that predict treatment outcome 6 months later (N = 190). We assessed eating disorder psychopathology, general psychopathology, personality characteristics and demographic variables using self-report questionnaires. Treatment outcome was measured using the bulimia subscale of the Eating Disorder Inventory 1. Predictors were determined using hierarchical linear regression analyses. Several variables significantly predicted outcome, four of which were found to be both baseline predictors of treatment outcome and end-of-treatment predictors of follow-up: Higher levels of drive for thinness, higher levels of interoceptive awareness, lower levels of binge eating pathology and, in women, lower levels of body dissatisfaction predicted better outcome in the short and longer term. Based on these results, several suggestions are made to improve treatment outcome for BED patients. Copyright © 2015 John Wiley & Sons, Ltd and Eating Disorders Association.
