RESUMO
INTRODUCTION: A robust instrument for measuring the educational environment in a pharmacy patient care setting is currently lacking. The authors aimed to develop a person-reported outcome measure to gauge trainee pharmacists' perceptions of their clinical workplace-based educational environment. This paper reports the various sources of validity evidence. METHODS: A preliminary, three-domain (system, relationship, and personal), 36-item measurement instrument was developed by incorporating results from literature review, focus group interviews, iterative discussions among educators, and cognitive interviews. The preliminary instrument, together with the Dundee Ready Educational Environment Measure (DREEM) and Orientation to Happiness Scale (OHS), were administered to trainee pharmacists recruited from one pharmacy school and one healthcare cluster in Singapore. Rasch analysis was conducted on the overall instrument as well as three domains: System, Relationship, and Personal. RESULTS: The 36-item instrument was administered to 145 learners, of which 66 were trainee pharmacists and 79 undergraduate interns. Upon removal of the middle "neutral" category to resolve poorly functioning categories and removal of five poorly functioning items, the overall instrument and its domains generally showed good fit with the Rasch model. Moreover, the overall 31-item Singapore Pharmacy Educational Environment Questionnaire (SPEEQ) and its three domains showed moderate to high convergent correlation with all the five DREEM domains and low to non-significant divergent correlation with the OHS Pleasure of Life subscale. CONCLUSIONS: Among one sample of pharmacy trainees, the 31-item SPEEQ and its three component domains demonstrated notable validity evidence to gauge trainees' perceptions of their learning environment.
