Health outcomes are organized in 3 categories: clinical, economic and humanistic (ex.: satisfaction). Larson et al developed and validated a multidimensional questionnaire - Pharmacy Services Questionnaire – to measure patient satisfaction with pharmaceutical care provided within the community pharmacies. The aims were translate the questionnaire and validate the Portuguese version. After translation, the Portuguese version was given out in April 2004, in 3 pharmacies chosen by convenience, to a convenience sample of usual patients (n=230), who where not included in a pharmaceutical care program/service. The instrument has 20 items (Likert - 5 levels) and it is self-administered, anonymous, confidential and voluntary. Portuguese version validation was done by evaluating the metric properties of the questionnaire. The translation result is the Portuguese version called Questionário sobre os Serviços da Farmácia, which has the following characteristics: 1. two factors extracted from the factor analysis: friendly explanation and managing therapy; 2. the reliabilities of the internal consistency of the scale, of the managing therapy dimension and friendly explanation dimension were very high, having alfa-Cronbach values respectively of 0,974, of 0,960 and of 0,939; 3. the construct validity was demonstrated by the convergent and discriminant validity evidence. The Portuguese version has a balanced structure, similar to the one presented in the original version and it revealed good metric properties, which justifies and facilitates its utilization in research and clinical environments.
