Patients are randomized to one of three different types of psychotherapy: Cognitive-Behavioral Therapy for adolescents, Family-Based Therapy for Bulimia Nervosa, and Supportive Psychotherapy. All treatments consist of 18 sessions over a period of approximately 6 months.
Behavioral: Cognitive Behavioral Therapy for Adolescents
The therapist will work with the adolescent to understand triggers to binge eating and purging, such as thoughts, feelings, and interpersonal difficulties. Also, establishing regular eating patterns and eliminating medically harmful behaviors associated with the eating disorder is a primary goal.Behavioral: Supportive Psychotherapy
SPT focuses on having the patient build a relationship with the therapist and explore their unique individual needs within the context of their life and the experience of having an eating disorder.Behavioral: Family Based Therapy for Bulimia Nervosa
FBT helps parents to take an active role in guiding their child through eating disorder treatment. In this therapy, the parents are supported in helping their child stop bingeing, purging and engaging in other harmful weight-control behaviors. The way in which the eating disorder has impacted the family and the adolescent's development is also explored.
BN is a serious disorder that is characterized by extreme concerns about body weight and shape, dieting, and the disinhibited eating behaviors of binging and purging. There are no published randomized clinical trials of psychotherapy treatment for Bulimia Nervosa in adolescents although it often onsets in this age group. There is evidence that some treatments are effective, but none has been empirically tested. Because Bulimia Nervosa is a serious medical and psychiatric illness it is important to learn efficacious ways to treat this disorder, especially in its early stages. Treatments used in this study are the best known treatments for adults with Bulimia Nervosa. The investigators hope to learn which of two previously studied treatments might be superior to the other, in an effort to guide clinicians in treatment choices. Successfully treating the disorder early on (even in those adolescents with partial BN, characterized by binge eating and purging at least one time per week over a 6 month period) may reduce the number of cases requiring treatment during adulthood, leading to possible reduction in severity of associated psychopathology and lower costs, as well as enable individuals to lead more productive lives.
Given the neglect of adolescent BN in the research literature and the need for information to guide the clinical treatment of this disorder, this study's primary aim is to compare the efficacy of CBT-A to FBT-BN in decreasing binge eating and purging episodes in adolescents with BN and partial BN (defined as binge eating and purging at least one time per week for the past six months).
Participation in this study will last 1 and a half years and will consist of 6 months of treatment and a follow-up session at 6 and 12 months post-treatment. All participants will first undergo baseline assessments, which include interviews and questionnaires about psychological history and BN symptoms, and an Eating Disorder Examination (EDE) interview. All treatment assignments consist of 18 sessions of therapy over the course of 6 months.
