COR program for treating binge eating in Chilean adults

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The COR protocol is a brief, manualized online psychological program that integrates body compassion, emotion-regulation skills, and conscious reconnection with food, drawing on CBT and DBT components. In this pilot interventional trial, participants complete a brief pre-session, eight weekly individual online sessions, and a one-month follow-up to capture short-term change. The study emphasizes implementation outcomes—feasibility, acceptability, adherence, and dropout—while also measuring preliminary changes in binge-eating distress and emotional well-being. Sessions use a non-weight-centered framework with experiential work on urges, cravings, and developing a more compassionate relationship with the body and eating.

Inclusion Criteria:

* Adults aged 18 years or older.
* Overweight or obesity, based on self-report.
* At least three binge-eating episodes in the past 30 days, associated with psychological distress.
* The presence of chronic medical conditions commonly associated with overweight or obesity (e.g., hypothyroidism, hyperthyroidism, dyslipidemia, hypertension, type 2 diabetes mellitus, or polycystic ovary syndrome) is permitted, provided that such conditions are medically stable.
* If present, chronic medical conditions must be medically stable, defined as:
* stable medical treatment for at least 12 weeks,
* no recent changes in medication,
* no acute clinical decompensation or recent major cardiovascular events,
* at least one related medical follow-up visit in the past 12 months.
* If present, psychopharmacological treatment must be stable, defined as no changes in medication type or dosage during the 12 weeks prior to enrollment.
* Daily access to the internet and to a computer or smartphone that allows participation in online sessions and assessments.

Exclusion Criteria:

* Current compensatory behaviors associated with binge eating, such as self-induced vomiting and/or regular use of laxatives, within the past 60 days.

  * Pregnancy or breastfeeding at the time of the initial assessment.
  * History of bariatric surgery.
  * Active suicidal ideation
  * Current symptoms consistent with severe mental disorders, such as psychotic disorders, bipolar disorder, complex post-traumatic stress disorder, or severe personality disorders, when associated with marked functional impairment or the need for specialized or higher-intensity clinical care.
  * Current substance use pattern that, due to its severity or functional impact, requires specialized clinical treatment.
  * Ongoing psychological and/or nutritional treatment at the time of enrollment, defined as regular sessions or an active treatment plan, regardless of treatment focus or therapeutic approach.
  * Presence of active or medically unstable conditions, characterized by clinically significant symptoms, lack of medical follow-up, or recent changes in medication, that could interfere with participation in the intervention or substantially affect eating behavior or mood.
  * Significant functional impairment that, in the clinical judgment of the research team, would limit the participant's ability to engage safely and consistently in the intervention.
