Professionalism encompasses the set of behaviors that inform and regulate the practice of health professionals. In the field of Pharmacy, professionalism can be examined through validated assessment instruments, such as the Modification of Hall’s Professionalism Scale for Use with Pharmacists. This study aimed to translate the Modification of Hall’s Professionalism Scale for Use with Pharmacists into Brazilian Portuguese and to assess its psychometric properties among pharmacists. The study followed a three-phase methodological approach. First, the original instrument was translated and cross-culturally adapted into Brazilian Portuguese. Second, content validity was established through expert consensus involving specialists from different geographic regions. Finally, the psychometric properties of the scale were evaluated using data collected from a convenience sample of 600 Brazilian pharmacists. Construct validity was examined through Exploratory Factor Analysis (EFA), and reliability was assessed using composite reliability estimates. The Brazilian Portuguese version of the instrument demonstrated satisfactory content validity, with coefficients exceeding the acceptable threshold of 0.80. Exploratory Factor Analysis supported a six-factor structure comprising 39 items. Additionally, the H index indicated high factor stability, and the scale exhibited adequate composite reliability. The adapted Brazilian Portuguese version of the instrument showed robust content validity and sound psychometric properties. This tool may serve as a valuable resource for future research on professionalism, particularly in relation to educational strategies and the evaluation of professionalism among pharmacists.
