Model adherence indicates the degree to which a program or intervention is delivered as intended. In integrated primary care, where mental health services are embedded into primary care clinics, appraisal of model adherence provides insight into whether these services align with key features of this unique practice environment (e.g., brief, interdisciplinary care). To date, such evaluations have emphasized system and provider factors. This study is a preliminary evaluation of whether a novel patient-facing measure, the Primary Care Behavioral Health Provider Adherence Questionnaire-Patient Version (PPAQ-Patient), can provide insight into adherence to the Primary Care Behavioral Health (PCBH) model of integrated primary care. Survey data were collected from 281 veterans who received PCBH care. Exploratory factor analyses evaluated the data structure. Results suggest that 19 items spanning three temporally-referenced subscales may feasibly capture patient perspectives on PCBH adherence at various stages of treatment. Future work is needed to refine the measure.
