Clinical Trial 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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Go/No-Go (GNG)	Performance on the Go/No-Go computer task will be used to assess changes in inhibitory control	Change from baseline to post-treatment and 3-month follow up
Other	Laboratory Sham Taste Test	An ecologically valid measure of inhibitory control specific to eating behavior, this task measures the amount of food that a participant consumes during a 10min interval when asked to taste the food presented	Change from baseline to post-treatment and 3-month follow up
Primary	Eating Disorder Examination (EDE)	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.	Change in binge frequency from baseline to post-treatment and 3-month follow-up
Secondary	Food Frequency Questionnaire (FFQ)	A modified version of the Food Frequency Questionnaire will be used to examine changes in binge eating on specific foods in the last month	Change from baseline to post-treatment and 3-month follow up
