PMH48 Validation of Pspsq Measuring Patient Satisfaction with Psychiatric Pharmacy Services

Abstract

To assess psychometric properties of the Patient Satisfaction with Pharmacist Services Questionnaire (PSPSQ) in a pharmacist-managed outpatient psychiatric care clinic. This descriptive, cross-sectional study was conducted at a pharmacist-managed psychiatric care clinic in a behavioral healthcare facility in Southern California between Nov. 2011 and Jan. 2012. Patients were included if they were ≥18 years of age and able to read English. PSPSQ consists of 22 items assessed on a four point Likert scale, and hypothesized to have three domains: patient-pharmacist relationship, quality of care and overall satisfaction. This study was approved by the Institutional Review Board for exempt status. PSPSQ has been previously tested for face and content validity and is being validated in other pharmacist managed Disease State Management clinics. Data collected following patients' visit were analyzed descriptively. Correlations were examined between age, gender, education, insurance status and patient satisfaction. Scale reliability was assessed using Cronbach's alpha and construct validity using factor analysis. Thirty-five participants completed the survey. Mean age of participants was 41 years, 54% were male, 37.9% were Caucasian and Hispanic each, 81% had some college education, and 80% were covered by private health insurance. Cronbach's alpha of the tool was 0.971 indicating very high reliability. After excluding two items, factor analysis yielded 19 items loading on three factors accounting for 79.6% of the variance. Only one item loaded on a factor different than hypothesized. The overall mean score of 3.5/4 indicated patient satisfaction with the pharmacist services they received. Patients with private insurance showed greater satisfaction compared to others (p<0.05). Our results suggest that the PSPSQ can serve as a reliable and valid tool for measuring patient satisfaction with pharmacist clinical services in a community/ambulatory care setting. Further research is needed to confirm its utility in other pharmacy practice settings.
