Communication About Medication by Providers-Adolescent and Young Adult Version: Confirmatory Factor Analyses.

OBJECTIVE To replicate the factor structure of a patient-report measure of provider communication about key medication prescription information, the Communication about Medication by Providers-Adolescent and Young Adult (CAMP-AYA) Version. We evaluated whether the 15-item, two-factor structure identified previously could be replicated via confirmatory factor analysis, and we also examined fit of unidimensional and bifactor models. Associations of CAMP-AYA Total and Factor Scores with provider satisfaction and select patient and medication characteristics were also examined. METHODS Participants were 739 AYA (ages 18-25) who completed the CAMP-AYA, a provider satisfaction rating, and provided demographic and medication information. RESULTS  The bifactor model was best fitting (χ2 [75] = 689.60, p .89) and Total and Factor Scores were associated with provider satisfaction (ps 30-day course) or refilled prescriptions (ps < .007) in most cases. CONCLUSIONS  This study provides additional support for the reliability of the CAMP-AYA as a tool to assess AYA perceptions of provider key information coverage about medication prescriptions.
