RESUMO
BACKGROUND: Professionalism is the demonstration of behaviors that guide the actions of health professionals. In Pharmacy, its implementation is possible through assessment instruments for pharmacists, such as the "Modification of Hall's Professionalism Scale for Use with Pharmacists". OBJECTIVE: To translate the "Modification of Hall's Professionalism Scale for Use with Pharmacists" into a Brazilian Portuguese version and evaluate its psychometric properties for pharmacists. METHOD: The methodological process of this study took place in three stages: translation and cross-cultural adaptation of the instrument original version into a Brazilian Portuguese version; validation of the scale content through consensus among geographically distinct experts and, finally; examination of the scale psychometric measurement properties through a convenience sample of 600 Brazilian pharmacists. At this stage, construct validity was verified using Exploratory Factor Analysis (EFA) and reliability was examined by calculating the composite reliability. RESULTS: The adapted instrument to a Brazilian Portuguese version demonstrated content validity with coefficients considered acceptable, above 0.8. The EFA demonstrated a structure supported by six factors and 39 items. The H index suggested high stability for all factors as well as composite reliability. CONCLUSION: The Brazilian Portuguese version of the instrument presented appropriate content validity coefficients and psychometric properties. This measure may be useful for future studies on professionalism regarding teaching strategies and assessment of this construct among pharmacists.
