Predictors of Treatment Outcome in an Early Intervention Eating Disorder Sample

Area of Science:

• Psychiatry
• Clinical Psychology
• Public Health

Background:

• Early intervention is crucial for treating recent-onset eating disorders (EDs) in adolescents and young adults.
• Identifying predictors of treatment success can optimize early intervention programs.

Purpose of the Study:

• To identify baseline predictors of treatment completion and clinical outcomes in individuals aged 16-25 receiving early intervention for EDs.
• To inform the development of more effective early intervention strategies for EDs.

Main Methods:

• Analysis of data from the FREED-Up study, including 228 participants (93% female, 63% White British).
• Utilized generalized estimating equations and linear mixed models to assess baseline predictors of treatment completion, symptom remission, and changes in ED symptoms, binge eating, purging, and BMI over 12 months.
• Examined predictors such as ED symptoms, depression, anxiety, stress, psychosocial impairment, and waiting times.

Main Results:

• No significant predictors of treatment completion were identified.
• Lower baseline stress predicted a higher likelihood of symptom remission.
• Lower baseline purging and psychosocial impairment predicted lower global ED symptoms and reduced binge eating.
• Shorter assessment waiting times were associated with reduced purging.

Conclusions:

• Psychosocial impairment and stress are important factors influencing treatment outcomes in early intervention for EDs.
• Findings highlight the need to consider these factors alongside ED symptoms and waiting times for optimizing recovery.
