Overview
Brief Summary
The primary aim of this study is to determine whether a computerized inhibitory control training (ICT) will improve CBT treatment outcomes for Bulimia Nervosa and Binge Eating Disorder.
Detailed Description
This study involves a brief phone screen and baseline assessment to determine eligibility. Participants who are eligible for the study will receive 12 sessions of CBT treatment and will be randomly assigned to an ICT or ICT sham condition which will consist of completing ICT computer tasks on a daily basis during the first four weeks of treatment and booster sessions following treatment. Participants will also complete research assessments at mid-treatment, post-treatment, and 3-month follow-up intervals. Research assessments include a battery of questionnaires, computerized tasks, interviews, and behavioral tasks.

Outcomes
Primary Outcomes
Eating Disorder Examination (EDE)
Time Frame: Change in binge frequency from baseline to post-treatment and 3-month follow-up
The Eating Disorder Examination is a widely utilized, semi-structured interview for the assessment of eating disorder symptoms and the binge-eating module will be used to determine binge episode frequency.
Secondary Outcomes
- Food Frequency Questionnaire (FFQ)(Change from baseline to post-treatment and 3-month follow up)
