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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Bulimia nervosa remission assessed by the Eating Disorder Examination Questionnaire (EDE-Q) | 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
| Measure | Time frame | Description |
|---|---|---|
| Change in Binge eating frequency assessed by the EDE-Q | baseline and post-treatment (Month 4) | Number of episodes of binge eating in past month |
| Change in Purging frequency assessed by the EDE-Q | baseline and post-treatment (Month 4) | Number of episodes of purging in past month |
| Change in eating disorder psychopathology assessed by the Eating Disorder Examination Questionnaire (EDE-Q) global score. | baseline and post-treatment (Month 4) | 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) | 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. |
| Change in Self-esteem assessed using the Rosenberg Self-Esteem Scale (RSES) | 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. |
