Abstract

The purpose of this study was to further validate the construct validity, reliability, and scaling properties of a previously developed 13-item instrument that measures pharmacy students attitudes toward pharmaceutical care, the Pharmaceutical Care Attitudes Survey (PCAS). The PCAS was distributed to 115 second-year professional pharmacy students at the University of Georgia in the Disease Management I course during November 1997. Eighty-nine students (77 percent) completed and returned the survey. Means and standard deviations for each of the 13-items and the three scales of the PCAS were calculated The distribution of item responses, item to intended scale total correlations, inter-scale correlations, item to competing scale correlations, item discriminant validity tests, and Cronbach's alpha were calculated. Overall, students have positive attitudes toward pharmaceutical care demonstrated by transformed scores of 84.38, 82.02, and 72.50 for the "professional benefit", "professional duty", and "return on effort" scales respectively (transformed scores ranged from 0 to 100 with higher scores representing more positive attitudes toward pharmaceutical care). The reliability estimates (Cronbach's alphas) of the three scales of the PCAS range from 0.69 to 0.93 and all item to scale correlations are greater than 0.40. Results of this investigation provide additional evidence that the PCAS is a reliable instrument and suggests that the PCAS is a valid instrument with three separate constructs.
