Development and validation of the pharmaceutical care satisfaction questionnaire.

The development and validation of a survey instrument to assess consumer satisfaction with pharmacy services is discussed. The Pharmaceutical Care Satisfaction Questionnaire (PCSQ) is a 30-item instrument administered by someone other than the pharmacist that uses a Likert scale to score respondents' answers. The PCSQ is written approximately at a seventh grade reading level. Following initial development, the PCSQ was administered to 360 consumers in ambulatory pharmacies and to 311 patients in a multicenter hyperlipidemia outcomes study. The Cronbach coefficient alpha was .94 for the consumer data, with a 64.8% variance accounted for by the 4-factor solution. A coefficient alpha of .84 was found on all 30 items in the hyperlipidemia study, with a variance of 63.78% in control patients and 60.16% in treatment patients. The PCSQ is easy to administer and score, with minimal cost. Unlike other satisfaction surveys, the PCSQ contains patient evaluations regarding outcomes of care. A primary limitation of the PCSQ is that it is a newly developed instrument that needs to be used in more studies to strengthen its validity.
