Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • age 18-55
  • meet DSM-5 criteria for Bulimia Nervosa (i.e., at least one episode of binge eating and compensatory behavior per week on average for the past 3 months) or Binge Eating Disorder (i.e., at least one episode of binge eating per week on average for the past 3 months).
  • be stable on psychiatric medications for at least 3 months

Exclusion Criteria:

  • have a diagnosis of anorexia nervosa or a BMI < 18.5
  • have extreme malnutrition or other medical complications that require acute hospitalization
  • are at acute suicide risk
  • are currently experiencing other severe psychopathology that would require a more intensive or specialized treatment program than the current study provides (e.g. severe depression, active psychotic disorder)
  • have previously completed a trial of CBT for Bulimia Nervosa or Binge Eating Disorder
  • have a diagnosis of an intellectual disability or autism spectrum disorder
  • currently taking stimulant medications
  • score of 95% or higher on 550ms block of Go/No-Go assessment task, indicating high inhibitory control at Baseline

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: CBT + ICT
Participants randomized to the ICT condition will complete a computerized ICT training at home during the first 4 weeks of treatment and ICT "boosters" following their treatment sessions during weeks 5-12.
Behavioral: CBT
Participants will complete 12 sessions of CBT
Behavioral: ICT
Participants will complete 4 weeks of daily inhibitory control trainings and "booster" ICT trainings following CBT treatment in weeks 5-12
Sham Comparator: CBT + sham
Participants randomized to the sham condition will complete a computerized sham ICT training at home during the first 4 weeks of treatment and sham ICT "boosters" following their treatment sessions during weeks 5-12. The shame will contain the same proportion of food as non-food but no inhibitory training component.
Behavioral: CBT
Participants will complete 12 sessions of CBT

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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.
Change in binge frequency from baseline to post-treatment and 3-month follow-up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Food Frequency Questionnaire (FFQ)
Time Frame: Change from baseline to post-treatment and 3-month follow up
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

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Go/No-Go (GNG)
Time Frame: Change from baseline to post-treatment and 3-month follow up
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
Laboratory Sham Taste Test
Time Frame: Change from baseline to post-treatment and 3-month follow up
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
