Fidelity refers to the extent to which a system, program or individual staff member adheres to a model or carries out a plan as intended. Research has confirmed the linkage between fidelity, the quality of intervention and ultimate system and individual-level outcomes. We have helped multiple systems identify, develop and adapt efficient, research-based tools to track adherence to a growing array of established practice models, including Multisystemic Therapy (MST), wraparound models, and assertive community treatment (ACT). We can help devise supervisory oversight processes based upon these tools that can improve service quality and also demonstrate to payers and other stakeholders that high quality services are provided. We can also help develop fidelity tracking tools to fit your system's unique needs.
