What is the purpose of this trial?

The investigators are doing a study of women with and without binge-eating disorder to learn more about what happens when people engage in everyday decision-making activities. The investigators are interested in learning more about brain activity during everyday decision-making and how everyday decision-making relates to a variety of daily experiences. Examples of everyday decisions include deciding which product to buy, deciding what to eat for a snack, and deciding how to spend free time.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but certain medications like insulin are excluded. It's best to discuss your specific medications with the trial team.

How does the decision-making treatment for binge eating disorder differ from other treatments?

This treatment is unique because it focuses on improving decision-making processes, such as cognitive flexibility and response inhibition, which are often impaired in individuals with binge eating disorder. It uses techniques like implementation intentions and mental imagery to help patients form and follow through on plans to change their eating behavior. ^{1 2 3 4 5}

What data supports the effectiveness of the treatment Speaking Activity, Talking Activity for Binge Eating Disorder?

The research suggests that treatments focusing on interpersonal functioning and self-reflection, like Speaking Activity and Talking Activity, may be beneficial for individuals with binge eating disorder, as these individuals often have significant social and interpersonal challenges and are motivated for treatment. ^{4 6 7 8 9}

This trial is for right-handed, young adult women with normal vision and hearing who are fluent in English. It's specifically for those with a BMI of 20-35 kg/m^2 and diagnosed with binge-eating disorder according to DSM-5 criteria. Women without eating disorders can also participate but must not have a personal or family history of such conditions.

Inclusion Criteria

Your body mass index (BMI) falls between 20 and 35, which means you are within a healthy weight range.

I have recently changed my mental illness treatment.

I am taking insulin.

What Are the Treatments Tested in This Trial?

Interventions

• Speaking Activity
• Talking Activity

Trial Overview The study examines brain activity during everyday decision-making tasks like shopping choices or planning leisure activities. Researchers aim to understand the differences between women with and without binge-eating disorder when they make these daily decisions.

How Is the Trial Designed?

Group I: Talking Activity and Speaking Activity Experimental Treatment 2 Interventions

Participants will engage in a talking activity first and a speaking activity second.

Group II: Speaking Activity and Talking Activity Experimental Treatment 2 Interventions

Participants will engage in a speaking activity first and a talking activity second.

Published Research Related to This Trial

A study of 424 adults with binge-eating disorder (BED) revealed that these patients experience significant functional impairment and interpersonal issues compared to non-clinical norms, indicating a need for targeted treatment strategies.

Patients with BED showed a high level of motivation for treatment, characterized by low resistance to interventions and high subjective distress, suggesting that they may benefit from longer, more intensive, and interpersonally focused therapeutic approaches.

Cognitive-behavioral therapy led by a therapist (CBTth) is significantly more effective than guided self-help (CBTgsh) for treating binge-eating disorder, with a 20-fold higher likelihood of treatment completion and nearly 15-fold higher likelihood of remission based on a study of 457 participants.

Weight concern plays a crucial role in treatment outcomes, with lower weight concern associated with better remission rates in both CBT methods, but longer treatment duration positively impacts remission in CBTth while negatively affecting CBTgsh.

In a study involving 64 adolescents with binge-eating disorder (BED), cognitive-behavioral therapy (CBT) showed excellent therapist adherence and therapeutic alliance, which are crucial for effective treatment.

The study found that patient characteristics, such as treatment expectations and the frequency of loss of control eating episodes, significantly influenced adherence and alliance, highlighting the need for tailored supervision in CBT for BED.

The 8-session internet-based guided self-help program for binge-eating disorder (BED) was well-accepted by participants, leading to a significant reduction in weekly binge-eating episodes from an average of 3.4 to 1.7, with improvements maintained during a 6-month follow-up.

Despite a dropout rate of 27% during treatment, the program showed high treatment satisfaction, and the addition of positive expectation induction before treatment did not enhance the effectiveness of the program.

A short-term Cognitive-Behavioral Treatment (CBT) for Binge Eating Disorder (BED) showed significant improvement in core symptoms during treatment, with benefits continuing or stabilizing over a four-year follow-up period for 41 patients.

Factors such as higher weight, increased eating concern, and more frequent binge episodes at the end of treatment were identified as predictors of long-term success, suggesting that personalized follow-up interventions could enhance treatment outcomes.

Implementation intentions (IIs) significantly reduced binge eating in a student sample over a 4-week period, with effects lasting for 6 months, indicating their efficacy in changing eating behaviors.

There was no additional benefit from using mental imagery (MI) alongside IIs, suggesting that simply forming 'if-then' plans may be sufficient for achieving long-term reductions in binge eating.

Female patients with binge eating disorder (BED) and obese women without BED showed poor decision-making abilities on the Iowa Gambling Task (IGT), indicating significant cognitive deficits in these groups.

Unlike normal weight women, those with BED and obesity did not improve their decision-making over time, and there was a direct link between their IGT performance and the severity of binge eating, suggesting a need for further research into the underlying cognitive processes.

A comprehensive review of 50 studies on Binge-Eating Disorder (BED) identified significant cognitive dysfunctions in decision-making processes, including deficits in Uncertainty Evaluation, Attentional Inhibition, Choice Consistency, and Cognitive Flexibility.

These findings suggest that targeting these specific cognitive processes through interventions could help address the treatment gap in BED, offering a new approach to managing the disorder.

Patients with binge eating disorder (BED) exhibit heightened food-related impulsivity, which is linked to their binge eating episodes and loss of control over eating.

The antisaccade task can be modified to serve as a training tool for BED patients, helping them practice suppressing impulsive responses to food stimuli, potentially improving their control over eating behaviors.
