Implementation Fidelity in Early Intervention for Eating Disorders-A Multisite Pilot Study

Area of Science:

• Clinical Psychology
• Public Health
• Healthcare Management

Background:

• Eating disorders affect young people, necessitating early intervention.
• The First Episode Rapid Early Intervention for Eating Disorders (FREED) model offers a pathway for recent-onset cases.
• Evaluating implementation fidelity is crucial for effective service delivery.

Purpose of the Study:

• To assess the feasibility of a new implementation fidelity tool for the FREED model.
• To examine fidelity patterns within the FREED early intervention service.
• To identify areas for improvement in service delivery for young people with eating disorders.

Main Methods:

• A multi-site study involving six eating disorder services in England.
• Data collection from 242 patient referrals and semi-structured interviews with FREED staff.
• Calculation of total and component fidelity scores (rapid access, care package) with inter-rater agreement assessment.

Main Results:

• The implementation fidelity tool was feasible, time-efficient, and showed high inter-rater agreement.
• Overall fidelity to the FREED model averaged 72% (medium fidelity).
• Rapid access targets scored 57% (unsatisfactory), while care package delivery scored 77% (medium fidelity), with significant variability in access.

Conclusions:

• Sustained resource augmentation is required to enhance adherence to the FREED model.
• Improvements are needed to meet rapid access targets consistently.
• Consistent access to high-quality early intervention for eating disorders requires further support and resource allocation.
