Implementation of an Adapted Fidelity Scale for Pennsylvania Coordinated Specialty Care Programs for First Episode Psychosis

Coordinated Specialty Care (CSC) is an evidence-based model for early intervention of first episode psychosis (FEP). Monitoring fidelity to CSC models is essential for proper evaluation of program outcomes and quality improvement. To address variability across CSC programs and fidelity assessment-associated burden, an adapted fidelity scale was developed and implemented statewide in Pennsylvania. This report describes the design and preliminary performance of the adapted scale. The Pennsylvania FEP Fidelity Scale (PA-FEP-FS) assesses adherence to the CSC model by focusing on essential model components of other established fidelity scales, in tandem with program evaluation data. Initial data from fourteen PA-FEP sites from 2018 to 2021 were examined as preliminary validation. Assessment-associated burdens and costs were also estimated. PA-FEP-FS captured essential components of CSC models and proved feasible for implementation across varying program structures, while minimizing burden and cost. Programs utilized annual feedback as CSC benchmarks, evidenced by increased scores over time. PA-FEP-FS provides a model for adapting CSC fidelity scales to meet state- or local-level requirements while reducing assessment burdens and costs that may be associated with existing scales.
