Study Overview
Brief Summary
This study will test the feasibility and acceptability of two treatments for adolescents with higher weight seeking treatment for bulimia nervosa (binge eating and purging, or going to extremes to lose weight).
Detailed Description
This study will test the feasibility and acceptability of two treatments for adolescents with higher weight seeking treatment for bulimia nervosa. Bulimia nervosa is when individuals binge eat (overeat while feeling like they lost control) and purge (do something extreme or unhealthy to lose weight or prevent weight gain). Bulimia nervosa happens across different ages and body sizes. This study is focusing on adolescents who have a larger body size. Adolescents will receive treatment that is 4 months of 45-minute sessions, weekly. Treatment will occur over telehealth (e.g., zoom), and the whole study is online.

Arms & Interventions
Cognitive Behavioral Therapy
Cognitive Behavioral Therapy for adolescents with higher weight seeking treatment for bulimia nervosa (CBT-BNh).Designed for adolescents, CBT-BNh will include psychoeducation, cognitive restructuring, and relapse prevention planning. The focus of therapy will include reducing extreme/unhealthy weight-control behaviors (purging) as well as binge eating, and self-compassion coping skills will address weight stigma and self-directed weight criticism.
Intervention: Cognitive Behavioral Therapy (Behavioral)
Mindfulness
Learning to Breathe (L2B) is an existing, evidence-based program for adolescents that teaches mindfulness skills each week, including time to practice and reflect. the skills are grouped into six themes: Body, Reflections, Emotions, Attention, Tenderness, Habits, and Empowerment.
Intervention: Mindfulness (Behavioral)
Outcomes
Primary Outcomes
Change in Bulimia nervosa remission assessed by the Eating Disorder Examination Questionnaire (EDE-Q)
Time Frame: baseline and post-treatment (Month 4)
Remission from binge eating and purging behaviors will be assessed by EDE-Q. The EDE-Q is a self-report questionnaire with four subscales and a global severity score. the global score ranges from 0-6 with higher scores reflecting greater severity of eating disorder behaviors.
Secondary Outcomes
- Change in Binge eating frequency assessed by the EDE-Q(baseline and post-treatment (Month 4))
- Change in Purging frequency assessed by the EDE-Q(baseline and post-treatment (Month 4))
- Change in eating disorder psychopathology assessed by the Eating Disorder Examination Questionnaire (EDE-Q) global score.(baseline and post-treatment (Month 4))
- Change in Depression assessed using Patient Health Questionnaire-9 (PHQ-9)(baseline and post-treatment (Month 4))
- Change in Self-esteem assessed using the Rosenberg Self-Esteem Scale (RSES)(baseline and post-treatment (Month 4))
