This study compared and combined fluoxetine and individual cognitive behavioral therapy in the treatment of bulimia nervosa. Participants were 76 women who sought treatment at the Eating Disorders Program of the Toronto Hospital and who met DSM-III-R criteria for bulimia nervosa. Subjects were randomly assigned to receive fluoxetine alone, cognitive behavior therapy alone, or the two in combination and were treated over 16 weeks. Short-term outcome revealed that all three treatment conditions were associated with clinical improvement across a wide range of parameters. The combination of pharmacotherapy and psychotherapy was superior to pharmacotherapy alone on specific parameters and there was no statistically significant advantage to the combination over psychotherapy alone. Limitations to the study include the absence of a placebo pill group and a waiting list control group as well as a substantial dropout rate across all three treatment conditions.

Forty-one women with bulimia nervosa completed a brief intervention that was designed to promote symptom management. Cutoff scores for the determination of reliable and clinically significant change were calculated for several psychometric instruments that are commonly used as outcome measures in the field of eating disorders. Using these statistical procedures to assess therapeutic change, this study documents the diversity of outcomes that individuals reported following their participation in the intervention. As expected, there was a differential reporting of clinically significant change in favor of specific eating psychopathology relative to personality features and associated psychopathology.

Forty-one subjects with bulimia nervosa completed a brief intervention that was designed to promote symptom management. A wide variety of clinical and psychometric variables were examined for their predictive utility in determining the clinical outcome of subjects after treatment. The following pretreatment variables were most strongly associated with a poor outcome : greater self-reported depression, higher frequency of vomiting, and a history of low adult body weight. Contrary to expectations, pretreatment levels of self-reported borderline organization were unrelated to outcome. It is suggested that subject by treatment interactions may partially account for the lack of robust prognostic factors which typifies the current treatment literature on bulimia nervosa

OBJECTIVE The present study examined whether additional sessions of group psychotherapy process (PP) would incrementally benefit bulimia nervosa (BN) subjects over and above that which is achieved through a course of brief group psychoeducation (PE). METHOD Utilizing a quasi-experimental design, the first cohort of 40 BN subjects completed five-session PE-alone groups that were highly didactic and explicitly devoid of group process work. The second cohort of 41 BN subjects completed 12-session PE + PP groups that integrated PE with more conventional cognitive-behavioral group process interventions. RESULTS Both treatments were associated with comparable levels of change on measures of specific and nonspecific psychopathology. Furthermore, the two treatments did not differ in rates of premature termination, in rates of remission in eating symptoms, in rates of normalization of scores on psychometric measures, or in consumer evaluation of the treatments. DISCUSSION While subjects value the opportunity to engage in psychotherapy process with other group members, the addition of seven such sessions offers no enhanced therapeutic benefit over five sessions of group PE.

OBJECTIVE The purpose of the study was to examine patterns of response to treatment in bulimia nervosa and to consider the utility of differentiating rapid from slower responders. METHOD Participants were 166 female patients with bulimia nervosa who received specialized day hospital treatment for their eating disorder and provided complete data on symptom frequencies over the course of treatment. Symptoms and psychological functioning were assessed at the beginning and end of treatment and 2-year follow-up information was available for a subsample of 57 patients. RESULTS A large subgroup (41%) of patients responded rapidly to treatment (i.e., symptom frequencies of three or less during the first 4 weeks of treatment) and a smaller subgroup (31%) were considered slower responders (i.e., symptom frequencies of four or more over the first 4 weeks of treatment and three or less over the last 4 weeks of treatment). The remaining patients were either partial responders (18%) or nonresponders (10%). Rapid responders tended to be older, less symptomatic, and less preoccupied with binging before treatment (all ps < .05), but the differences were not strong. Rapid responders also had better symptom control at the end of treatment (p < .00001), were less likely to receive antidepressant/antibulimic medication during the program (p < .04), and were significantly less likely to relapse within 2 years of attending the program (p < .005). DISCUSSION These findings demonstrate that a significant subgroup of severely ill bulimia nervosa patients had a rapid, strong, and enduring response to intensive treatment, but could not be well identified with the available measures before treatment.

Interest in assessing Personality Disorders (PDs) in association with anorexia nervosa (AN) and bulimia nervosa (BN) has been accompanied by the development of several structured interview and self-report measures. In an attempt to see how the self-report Millon Clinical Multiaxial Inventory (MCMI-II) compared with the Structured Clinical Interview for DSM-III-R (SCID-II) in the assessment of PDs, we gave both instruments to 43 inpatients with a diagnosis of AN or BN. Correlation coefficient values for both categorical and dimensional comparisons were generally less than .4. Although comparable rates of positive PDs occurred for each of the three clusters (A: 30.2% vs. 34.9%, B: 25.6% vs. 18.6%, and C: 62.8% vs. 81.4% for SCID-II vs. MCMI-II), agreement for individual diagnosis and individual subjects was poor. In conclusion, the MCMI-II did not prove to be a reliable instrument for assessing axis II PDs in patients with AN and BN when compared with the SCID-II.
