Open or close this module Study Description
Brief Summary: The current study will use a full factorial design to identify the independent and combined effects of four core MABT components when combined with standard behavioral treatment for BN and BED. The primary aim of the study will be to evaluate the independent efficacy of Mindful Awareness, Distress Tolerance, Emotion Modulation, and Values-Based Decision Making on eating pathology (at posttreatment and at 6 and 12-month follow-ups). Secondary aims will be (1) to test target engagement of each MABT component, i.e., to confirm that each treatment component impacts both the variable which it targets and self-regulation and that improvements in these are associated with improvements in outcomes and (2) to test the hypotheses that the efficacy of each component is moderated by related baseline deficits in self-regulation (e.g. individuals with worse distress tolerance at baseline are most likely to benefit from conditions that include the Distress Tolerance component). A final exploratory aim will be to quantify the component interaction effects, which may be partially additive (because components overlap and/or there is diminishing return), fully additive, or synergistic (in that components may partially depend on each other).

Open or close this module Outcome Measures
Primary Outcome Measures:
1. Binge eating frequency assessed by the Eating Disorder Examination
[ Time Frame: Changes from each assessment time point throughout treatment (3 assessments over 16 weeks) and 6-month and 1 year post-treatment follow-up assessment ]

Frequency (number of days and number of instances) of binge eating over the past 28 days assessed by the Eating Disorder Examination
2. Eating Disorder Examination
[ Time Frame: Changes from each assessment time point throughout treatment (3 assessments over 16 weeks) and 6 month and 1 year post-treatment follow-up assessment ]

The Eating Disorder Examination is a semi-structured interview that measures eating pathology. The EDE yields four subscale scores: Restraint, Eating Concern, Shape Concern, and Weight Concern. The possible score range for each subscale is 0 to 6. The total score may also be reported (determined by averaging the subscale scores); the score range for the total score is also 0 to 6. For subscale scores and total score, higher scores indicate more severe pathology. The restraint sub-scale of the EDE will be used to assess utilization of skills related to reducing dietary restraint.
3. Remission Status
[ Time Frame: Changes from each assessment time point throughout treatment (3 assessments over 16 weeks) and 6 month and 1 year post-treatment follow-up assessment ]

Presence or absence of eating disorder diagnosis. Not in remission; in partial remission; or in full remission.
Secondary Outcome Measures:
1. Compensatory behavior frequency assessed by the Eating Disorder Examination (EDE)
[ Time Frame: Changes from each assessment time point throughout treatment (3 assessments over 16 weeks) and 6 month and 1 year post-treatment follow-up assessment ]

Frequency (number of days and number of instances) of compensatory behaviors assessed by the Eating Disorder Examination
2. BMI
[ Time Frame: Changes from each assessment time point throughout treatment (3 assessments over 16 weeks) and 6 month and 1 year post-treatment follow-up assessment ]

kilogram/(meters^2), this is an outcome measure for participants with anorexia nervosa, binge/purge type
