Development of a scale to determine student self-efficacy in performing key pharmacists’ patient care skills

Background: The Pharmacists' Patient Care Process (PPCP) was developed to describe a consistent process in which pharmacists in any setting provide patient care. Faculty at a midwestern university developed and refined an assessment tool which provides an indirect approach to measure student confidence in performing skills essential to the PPCP. The objective of this paper is to conduct a stepwise factor analysis to refine the PPCP survey. Methods: Assessing appropriateness of survey response data led to an exploratory factor analysis (EFA) on student confidence data to refine the survey instrument and examine the underlying constructs that influence student responses. Post EFA, the results were presented to the research team that collaboratively reached consensus on inclusion or exclusion of items. Results: EFA factor loadings identified a 4-factor solution suggesting elimination of 30 items from the original 53 item survey. Team discussions led to eliminating 29 items, combining two items and generation of 5 new items in order to retain important concepts. The outcome was a well-conceptualized and refined 29 item-survey model assessing 4 constructs. Conclusion: To potentially improve patient outcomes, it is imperative to utilize comprehensive yet concise survey instruments, like the PPCP Skills Self-Efficacy Survey, to prepare students to translate PPCP skills to practice.
