Background Understanding patient satisfaction with pharmacy services can help to enhance the quality and monitoring of pharmacy services. Patient Satisfaction with Pharmacist Services Questionnaire 2.0 (PSPSQ 2.0) is a valid and reliable instrument for measuring patient satisfaction with services from the pharmacist. The availability of the PSPSQ 2.0 in Nepalese version would facilitate patient satisfaction and enhance pharmacy services in Nepal. This study aims to translate the PSPSQ 2.0 into the Nepalese version, culturally adapt it and verify its reliability and validity in the Nepalese population. Methods The methodological and cross-sectional study design was used to translate, culturally adapt it, and validate PSPSQ 2.0 in Nepalese. The Nepalese version of PSPSQ 2.0 went through the full linguistic validation process and was evaluated in 300 patients visiting different community pharmacies in Kathmandu district, Nepal. Exploratory factor analysis was carried out using principal component analysis with varimax rotation, and Cronbach's alpha was used to evaluate the reliability. Results Three-hundred patients were recruited in this study. Participants ranged in age from 21 to 83 years; mean age was 53.93 years (SD: 15.21). 62% were females, and 34% educational level was above 12 and university level. Only 7% of the participants were illiterate. Kaiser- Meyer-Olkinwas found to be 0.696, and Bartlett's test of sphericity was significant with a chisquare test value of 3695.415. A principal axis factor analysis conducted on the 20 items with orthogonal rotation (varimax). PSPSQ 2.0 Nepalese version (20 items) had a good internal consistency (Cronbach's alpha = 0.758). Item-total correlations were reviewed for the items in each of the three domains of PSPSQ 2.0. Conclusion The PSPSQ 2.0 Nepalese version demonstrated acceptable validity and reliability, which can be used in the Nepalese population for evaluating the satisfaction of patients with pharmacist services in both community pharmacy and research.
