OBJECTIVES: Patient satisfaction is a critical component of health care performance in all settings including pharmacy-provided services. Our study aimed to assess the validity and reliability of a newly developed survey used to evaluate patient satisfaction of an employer-sponsored medication therapy management (MTM) program provided in an independent pharmacy setting. METHODS: This exploratory study used a cross-sectional design. The survey was developed using three previous instruments and using input from practicing pharmacists. The instrument consisted of three sections (experience with the pharmacist, pharmacy, and pharmacy staff). Face validity was assessed by a review panel of practicing pharmacists and researchers. Final survey consisted of thirty-four items. A five-point Likert scale (1 = strongly disagree to 5 = strongly agree) was used. Data was collected over a one-year period and analyzed using SPSS v. 17.0. Construct validity was assessed by an exploratory factor analysis using the principal components method and a varimax rotation. Internal consistency reliability was tested using Cronbach’s alpha. RESULTS: Factor analysis with varimax rotation (n= 171) resulted in five dimensions. Upon assessment, we labeled the factors as Experience with the Pharmacist, Experience with the Pharmacy, Experience with the Pharmacy Staff, Satisfaction of Pharmacy Care, and Prescription Promptness. The KMO measure of sampling adequacy was .954. Experience with the pharmacist accounted for 62.86% of the variance with the eigenvalue of 21.373. Cronbach’s alpha for the five dimensions was found to be .977, .927, .975, .962, .868, respectively. CONCLUSIONS: Results indicate the survey demonstrates validity and reliability. With health care moving towards a more patient-centered approach and an increasing need to have patients evaluate services provided, the instrument developed for this study could serve as a valuable tool. Pharmacists may utilize this tool to assess their own MTM programs. However, additional testing in other pharmacy settings is recommended for further assessment.
