Psychometric assessment of the Primary Care Behavioral Health Provider Adherence Questionnaire (PPAQ).

Adherence to protocol among behavioral health providers working in co-located, collaborative care or Primary Care Behavioral Health settings has rarely been assessed due to limited measurement options. Development of psychometrically sound measures of provider fidelity may improve the translation of these service delivery models into every day practice. One hundred seventy-three integrated behavioral health providers in VA primary care clinics responded to an online questionnaire to assess the reliability and validity of the Primary Care Behavioral Health Provider Adherence Questionnaire (PPAQ). Psychometric assessment resulted in a reliable 48-item measure with two subscales that specified essential and prohibited provider behaviors. The PPAQ demonstrated strong convergent and divergent validity when compared to another measure of health care integration. Known-group comparisons provided partial support for criterion validity. The PPAQ is a reliable and valid self-report of behavioral health provider fidelity with implications for improving provider training, program monitoring, and clinical research.
