The goal of this clinical study is to learn whether a brief online psychological program called COR can be delivered in a feasible and acceptable way for adults who experience recurrent binge eating.
The main questions this study aims to answer are:
Participants in this study are adults who experience recurrent episodes of binge eating. They will take part in an individual online intervention that includes eight weekly sessions, a brief pre-session, and a follow-up session one month after the end of treatment.
During the study, participants will:
The information from this study will help researchers understand whether this type of intervention can be used in future, larger studies and in real-world clinical settings.
This study evaluates the COR protocol (Body Compassion-Emotional Regulation-Conscious Reconnection with Food), a brief, manualized psychological intervention designed for adults who experience recurrent binge eating. The study is conducted as a pilot trial to examine implementation-related outcomes and to explore preliminary clinical changes over time.
The COR protocol was developed by integrating evidence-informed components from cognitive-behavioral therapy for eating disorders, dialectical behavior therapy skills, and approaches that promote a more conscious and flexible relationship with eating. The intervention is grounded in a non-weight-centered framework and places emphasis on emotional regulation, experiential work with urges and cravings, and the gradual development of a more compassionate relationship with the body and eating.
The intervention is delivered individually in an online format and consists of eight weekly sessions, preceded by a brief pre-session and followed by a one-month follow-up session. Sessions follow a structured but flexible progression, organized around a defined trajectory of change. Early sessions focus on establishing a therapeutic framework, understanding binge eating as a functional and emotionally driven behavior, and identifying personal vulnerability patterns. Middle sessions emphasize skills for relating differently to urges and emotional distress, including experiential and regulation-based strategies. Later sessions focus on body-related self-criticism, compassion-based practices, consolidation of skills, and planning for continuity of care and relapse prevention.
Each session includes a combination of psychoeducation, guided experiential exercises, reflective discussion, and brief between-session practices. Between-session tasks are designed to support observation and reflection rather than performance or compliance, and difficulties completing tasks are addressed as clinically meaningful information rather than treatment failure.
The protocol is manualized to support consistency across providers while allowing controlled clinical flexibility in pacing, examples, and depth of exploration, according to participant needs. Core components of each session and overarching therapeutic principles are defined as non-modifiable to preserve fidelity to the model.
As part of the study design, the COR protocol is implemented by psychologists with general clinical training who receive structured training in the model prior to implementation, as well as ongoing weekly clinical supervision during the intervention period. Therapist adherence to the protocol is supported through the use of structured adherence checklists, which are intended for monitoring and quality assurance rather than performance evaluation.
This pilot study focuses on outcomes related to feasibility and acceptability of the intervention when delivered online, including aspects of recruitment, retention, adherence, and participant satisfaction. In addition, the study explores preliminary changes over time in binge eating-related symptoms and associated emotional and psychological processes. Data from this pilot will be used to inform refinements to the protocol and the design of future larger-scale studies.

Behavioral: COR Protocol (Body Compassion - Emotional Regulation - Conscious Reconnection with Food)
The COR protocol (Body Compassion-Emotional Regulation-Conscious Reconnection with Food) is a brief, manualized psychological intervention designed to address recurrent binge eating in adults. The intervention is delivered individually in an online format and consists of eight weekly sessions, preceded by an initial pre-session and followed by a one-month follow-up session. COR integrates elements from cognitive-behavioral therapy for eating disorders, dialectical behavior therapy skills, and principles of intuitive eating, within a non-weight-centered and compassion-focused framework. The intervention targets key psychological processes involved in binge eating, including emotional regulation, responses to food-related urges and cravings, and the development of a more compassionate relationship with the body and eating. Sessions include psychoeducation, functional analysis of binge episodes, experiential exercises, brief regulation practices, and reflective between-session activities.
Proportion of Eligible Participants Who Initiate the COR Intervention
Recruitment rate is defined as the proportion of eligible individuals who begin the COR intervention, calculated as the number of eligible participants who start the intervention divided by the number of eligible individuals who were successfully contacted and formally invited to participate during the recruitment period.
Time frame: At enrollment.
Proportion of Participants Who Complete All Eight COR Intervention Sessions
Retention during the intervention is defined as the proportion of participants who complete all eight scheduled COR intervention sessions.
Time frame: Up to 8 weeks.
Proportion of Participants Who Attend the 1-Month Follow-Up Session After Completing the COR Intervention
Retention at follow-up is defined as the proportion of participants who completed the eighth COR intervention session and subsequently attended the 1-month follow-up session.
Time frame: Up to 12 weeks.
Proportion of Participants Who Discontinue the COR Intervention Before Completing All Eight Sessions
Dropout rate is defined as the proportion of participants who discontinue the COR intervention before completing all eight scheduled sessions. When available, participants' self-reported reasons for discontinuation will be recorded descriptively.
Time frame: Up to 8 weeks.
Proportion of Scheduled Assessment Instruments Completed by Participants
Assessment completeness is defined as the proportion of scheduled assessment instruments completed by participants relative to the total number of instruments planned. This includes both formal assessment batteries administered at predefined study time points and weekly monitoring measures collected during the intervention period. This outcome evaluates the feasibility of data collection procedures.
Time frame: From baseline through 12 weeks.
Acceptability of the COR Protocol Among Participants and Interventionists
Acceptability of the COR protocol will be assessed using both participant- and interventionist-reported indicators. Participant acceptability will be assessed at post-treatment using the Client Satisfaction Questionnaire (CRES-4), which captures overall satisfaction with the intervention and perceived usefulness. Participant experiences regarding the intervention format, duration, contents, and strategies will be further explored through semi-structured qualitative interviews conducted after completion of the intervention. Interventionist acceptability will be assessed through semi-structured qualitative interviews focused on perceived adequacy, usability, and fit of the COR protocol within the clinical context.
Time frame: At completion of the eighth COR intervention session (session 8).
Implementation Fidelity of the COR Protocol
Implementation fidelity of the COR protocol will be assessed by evaluating whether the intervention is delivered as intended. This includes assessment of (a) adherence to the core contents, objectives, and strategies specified for each session, (b) quality of intervention delivery (e.g., structure, clarity, and consistency with the COR model), and (c) participant exposure to the intervention (dose received), operationalized through session attendance, session duration, and completion of between-session tasks. Fidelity indicators will be primarily collected using a therapist-completed adherence checklist administered after each session, complemented by attendance and session-duration records. Descriptive information regarding implementation challenges and adaptations will also be recorded to support monitoring and future refinement of the protocol.
Time frame: From the first COR intervention session (session 1) through completion of the eighth COR intervention session (session 8), assessed over 8 weeks.
Change in Binge-Eating Symptoms
Changes in binge-eating symptoms, including the frequency and severity of binge-eating-related behaviors and associated distress, will be assessed using validated self-report measures, including the Eating Disorder-15 (ED-15) and the Binge Eating Disorder Screener-7 (BEDS-7). In addition to the predefined assessment time points, the ED-15 will be administered weekly during the intervention period for monitoring purposes.
Time frame: From baseline through 12 weeks.
Change in General Psychological Distress (CORE-OM)
General psychological distress will be assessed using the Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM), a self-report questionnaire that measures overall psychological distress and well-being. This outcome will be used to describe changes in general distress during and after participation in the COR intervention and to support monitoring of participant well-being.
Time frame: From baseline through 12 weeks.
Change in Difficulties in Emotion Regulation (DERS)
Difficulties in emotion regulation will be assessed using the Difficulties in Emotion Regulation Scale (DERS), a self-report questionnaire that measures difficulties in understanding, accepting, and managing emotions. This outcome will be used to describe changes in emotion regulation difficulties following participation in the COR intervention.
Time frame: From baseline through 12 weeks.
Change in Body Compassion
Changes in body compassion will be assessed using the Body Compassion Scale (BCS), a self-report measure designed to assess compassionate attitudes toward the body.
Time frame: From baseline through 12 weeks.
Change in Emotional Eating
Changes in emotional eating will be assessed using the emotional eating subscale of the Dutch Eating Behavior Questionnaire (DEBQ-EE), a self-report measure of eating in response to emotional states.
Time frame: From baseline through 12 weeks.
Plan to share: No — Individual participant data will not be shared due to the sensitive nature of the data collected (mental health and eating-related behaviors), the small sample size of this pilot study, and the lack of explicit participant consent for data sharing.
