BackgroundIn the absence of similar studies in Lebanon, this study aimed at upgrading and validating the Lebanese specialized competencies framework for community pharmacists (SCF-CP) as a tool to transform community practice and support the professional development and career progression of community pharmacists.MethodsContent validity was assessed and improved through a team of experts. After a thorough literature review and utilizing the Delphi technique, six domains were defined in the framework, with their respective competencies and behaviors. A cross-sectional study was then carried out from March to October 2022 using an online questionnaire created on Google Forms. The snowball technique was applied to reach community pharmacists across all the Lebanese governorates.ResultsThe final sample included 512 community pharmacists. The construct validity of the framework was confirmed by factor analysis. The Kaiser–Meyer–Olkin measures of sampling adequacy were satisfactory for all models ranging from 0.500 to 0.956 with a significant Bartlett’s test of sphericity (P< 0.001). The internal consistency of all competency domains was confirmed by Cronbach’s alpha, with values ranging from 0.803 to 0.953. All competencies were significantly correlated with their respective domains (P< 0.001), and all domains were significantly correlated with each other and with the framework (P< 0.001). The participants declared being competent in all domains relating to fundamental skills, safe and rational use of medicines, pharmacy management, professional skills, public health fundamentals, and emergency preparedness and response, with some exceptions, such as compounding, management, and emergency preparedness. A higher declared competency level was associated with having more experience and receiving more than 50 patients per day.ConclusionOur findings could demonstrate that the Lebanese specialized competency framework is a valid and reliable tool. This framework could help assess the minimum competencies that community pharmacists should possess or acquire and direct initial and continuing education for better practice. Hence, it could be adopted by the authorities and implemented in the Lebanese community pharmacy setting.Supplementary InformationThe online version contains supplementary material available at 10.1186/s40545-023-00585-6.
