The goal of proposed project is to strengthen the public health impact of psycho-social interventions by identifying fidelity measurement methods that can be used for research and practice.  To date, fidelity has posed a thorny measurement quandary because few reliable, valid, and efficient fidelity measurement methods exist. The gold standard for measuring fidelity to psycho-social interventions, direct observation of therapist behavior, requires extensive resources. When fidelity is measured in the community, the most commonly used and least resource intensive method is self-report. Unfortunately, concordance between observation and self-report is low.  

There is a critical need to identify and evaluate methods of fidelity measurement that are accurate (i.e., measure what they intend) and cost-effective. Our objective in this measurement proposal is to compare the accuracy and cost-effectiveness of three methods: self-report, chart stimulated recall and behavioral rehearsal in assessing fidelity to cognitive-behavioral therapy, an established evidence-based practice. We will randomize 135 therapists, trained in cognitive-behavioral therapy through an initiative to implement evidence-based practices in the City of Philadelphia, to 3 conditions: self-report (N = 45), chart stimulated recall (N = 45), and behavioral rehearsal (N = 45). All conditions will include direct observation using the Therapy Process Observational Coding System as the gold-standard comparison. In Aim 1, we will identify the most accurate fidelity measurement method. In Aim 2, we will estimate the economic costs and cost-effectiveness of the proposed fidelity measurement methods. In Aim 3, we will compare stakeholders’ willingness to use each method, as well as identify their perceived barriers and facilitators to use of each method. The proposed work is consistent with the NIMH strategic plan, specifically Objective 4, to strengthen the public health impact of NIMH-supported research.

This study will have a significant positive impact by producing fidelity measurement methods that can then be used by implementation scientists for research and community mental health clinics to monitor therapist fidelity, an indicator of therapy quality.
