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.

Intervention / Treatment |
---|---|
Experimental: 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.
|
Cognitive Behavioral Therapy (CBT) is a psychological treatment or "talk therapy" that integrates how people think, feel, and behave to create new behavior patterns that improve thinking processes and reduce distress.
|
Active Comparator: 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.

Mindfulness is a psychological treatment or "talk therapy" that practices different coping skills to improve thinking processes and reduce distress.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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.

|
Eating disorder psychopathology will be assessed using the EDE-Q global score.
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 psychopathology.

|
Change in Depression assessed using Patient Health Questionnaire-9 (PHQ-9)
Time Frame: baseline and post-treatment (Month 4)
|
Depression will be assessed using the PHQ-9.
PHQ-9 is a validated questionnaire used to screen for depression with a range of scores from 0-27.
Higher scores indicate more severe depressive symptoms.
|
baseline and post-treatment (Month 4)
|
Change in Self-esteem assessed using the Rosenberg Self-Esteem Scale (RSES)
Time Frame: baseline and post-treatment (Month 4)
|
Self-esteem will be assessed using the RSES.
The RSES is a self-report measure that consists of 10 statements related to overall feelings of self-worth or self-acceptance.
The items are answered on a four-point scale ranging from strongly agree to strongly disagree.
The total score ranges from 0 to 30 with higher scores indicating higher self esteem.
