Predicting premature termination within a randomized controlled trial for binge-eating patients

Area of Science:

• Psychology
• Psychiatry
• Clinical Psychology

Background:

• Binge eating disorder (BED) is a growing concern.
• Dropout rates from psychotherapy for BED are high and poorly understood.
• Psychotherapy process characteristics as predictors of dropout in BED are under-researched.

Purpose of the Study:

• To investigate if early psychotherapy process characteristics predict premature termination in BED patients.
• To examine the role of therapeutic relationship, mastery, and motivational clarification in treatment dropout.
• To identify specific in-session experiences linked to therapy discontinuation.

Main Methods:

• A randomized controlled trial (N=78) involving patients with BED.
• Analysis of postsession reports from Sessions 1 to 5.
• Statistical control for covariates: rapid treatment response, treatment group, BMI, Axis II disorder, and baseline self-efficacy.

Main Results:

• Low in-session self-esteem experiences consistently predicted premature termination.
• This predictive value remained significant after controlling for covariates.
• Exploratory analyses identified low self-esteem, low global alliance, and low mastery/clarification as predictors for patients citing therapy discontentment.

Conclusions:

• In-session self-esteem experiences appear to be a crucial factor in BED patients' decision to stay or withdraw from psychotherapy.
• These self-esteem experiences may be general mechanisms influencing treatment adherence, not just symptoms of psychopathology.
• Therapist training and evaluation should consider early psychotherapy process characteristics, particularly self-esteem, to improve treatment retention in BED.
