| Abstract: | A controlled study evaluating the effectiveness of exposure plus response-prevention treatment of bulimia nervosa was conducted in a sample of 47 women. This was a four-group comparison involving three treatment conditions and a waiting-list control group. The three treatment conditions were (a) exposure plus response prevention conducted in a single setting (clinic), (b) exposure plus response prevention conducted in multiple settings (clinic, patients' homes, and restaurants), and (c) cognitive–behavioral therapy without exposure plus response prevention. All treatment was provided to groups of 3 patients at a time. Outcome was evaluated at posttreatment and at a 6-month follow-up. The three treatment groups improved significantly on most outcome measures, whereas the waiting-list control group showed little change. At follow-up, there was a slightly better outcome on vomiting behavior and amount of food consumed in one of the test meals for the exposure plus response-prevention groups relative to the no-exposure group. However, on all other measures, the degree of improvement from pretreatment to follow-up was the same for all three treatment groups. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
