Instruments for Measuring Patient Satisfaction with Pharmacy Services in the Spanish Language

Abstract

The purpose of this paper is to identify and evaluate instruments used to assess patient satisfaction with pharmacy services available in the Spanish language, and specifically those designed to assess pharmaceutical care provided in community pharmacies. A literature search was conducted in seven databases, using keywords: "patient satisfaction" and "Spanish" with and without the term "pharmacy". Publications that described the development or translation and/or adaptation of a questionnaire to assess patient satisfaction with pharmacy services in the Spanish language were retained. Publications were excluded if they were abstracts from conferences, reviews, letters or notes. The criteria used also excluded manuscripts where patient satisfaction was not assessed with a questionnaire. Instruments were evaluated according to evidence of the psychometric properties considered relevant: content validity, reliability and construct validity. While 83 publications describing instruments to measure patient satisfaction with health care services in the Spanish language were identified, only two pertained to satisfaction with pharmacy services. Both assessed patient satisfaction with pharmaceutical care. One questionnaire, developed in Spanish only, includes four dimensions that comprehensively assessed pharmaceutical care practice; however, its reliability was only partially evaluated. The other questionnaire was developed in both Spanish and English. It was considered narrower in scope, assessing satisfaction with the pharmacist only. However, evidence was provided that the two versions of the questionnaire were reliable, valid and linguistically equivalent. A comprehensive, reliable, and valid instrument for assessing patient satisfaction with pharmaceutical care in community pharmacies in the Spanish language is not yet available. The two published questionnaires that we have identified are a beginning, further research and development is needed.
