About this study

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).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Behavioral Therapy for Eating DisordersBehavioural

    Change behaviors that maintain binge eating (e.g. rigid dietary restriction outside of binge episodes, irregular or chaotic eating patterns).

  • MABT: Mindful AwarenessBehavioural

    Integrates behavioral treatment for eating disorders with a set of psychological strategies, specifically mindful awareness, designed to enhance self-regulation. Mindful awareness strategies include developing inner and outer wisdom, formal meditation, and shifting awareness to the present moment. Mindful awareness skills also include increasing awareness of thoughts, feelings, physical sensations, and hunger and fullness cues.

  • MABT: ValuesBehavioural

    Integrates behavioral treatment for eating disorders with a set of psychological strategies, specifically values, designed to enhance self-regulation. Values skills include identifying and clarifying values, living a values life, making values-consistent decisions, addressing competing values, values awareness, and using values to address negative moods.

  • MABT: Emotion ModulationBehavioural

    Integrates behavioral treatment for eating disorders with a set of psychological strategies, specifically emotion modulation, designed to enhance self-regulation. Emotion modulation skills include long-term habits for emotion regulation, coping strategies, crisis management, and cognitive reappraisal.

  • MABT: Distress ToleranceBehavioural

    Integrates behavioral treatment for eating disorders with a set of psychological strategies, specifically distress tolerance, designed to enhance self-regulation. Distress tolerance skills include psychological acceptance, uncoupling, willingness, and dealing with dirty distress.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Binge eating frequency assessed by the Eating Disorder Examination

    Frequency (number of days and number of instances) of binge eating over the past 28 days assessed by the Eating Disorder Examination

    Measured: Changes from each assessment time point throughout treatment (3 assessments over 16 weeks) and 6-month and 1 year post-treatment follow-up assessment

  2. Eating Disorder Examination

    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.

    Measured: Changes from each assessment time point throughout treatment (3 assessments over 16 weeks) and 6 month and 1 year post-treatment follow-up assessment

  3. Remission Status

    Presence or absence of eating disorder diagnosis. Not in remission; in partial remission; or in full remission.

    Measured: Changes from each assessment time point throughout treatment (3 assessments over 16 weeks) and 6 month and 1 year post-treatment follow-up assessment

Secondary outcomes (2)
  1. Compensatory behavior frequency assessed by the Eating Disorder Examination (EDE)

    Frequency (number of days and number of instances) of compensatory behaviors assessed by the Eating Disorder Examination

    Measured: Changes from each assessment time point throughout treatment (3 assessments over 16 weeks) and 6 month and 1 year post-treatment follow-up assessment

  2. BMI

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

    Measured: Changes from each assessment time point throughout treatment (3 assessments over 16 weeks) and 6 month and 1 year post-treatment follow-up assessment

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 25 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

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). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Sep 2023.
