Validity and Reliability of a Questionnaire on Attitudes, Knowledge, and Perceptions of Pharmacy Students Regarding the Training Received on Antibiotics and Antimicrobial Resistance during Their University Studies.

Abstract

Antimicrobial resistance is a major public health issue today. Therefore, it is essential to focus on the education of pharmacists as future dispensers. The objective of this study was to validate a questionnaire that assesses the knowledge, attitudes, and perceptions of pharmacy students regarding the education received during their university degree on the use and dispensation of antibiotics, as well as bacterial resistance. An online questionnaire was developed and distributed via RedCap v.13.7.1 to pharmacy students at the University of Santiago de Compostela using the WhatsApp social network. The questionnaire consisted of 28 items evaluating 5 dimensions: "quality of care", "communication skills", "antibiotic resistance", "teaching methodology", and "education on antibiotics at the faculty". The questionnaire validation was conducted in 2 steps: Step 1 involved content and appearance validation, and Step 2 involved reliability analysis. A total of 61 completed questionnaires were received. The mean age was 21.82 ± 3.81 years, with 20 males (32.8%) and 41 females (67.2%). Content validation was performed through a nominal group of 5 experts, and appearance validation was conducted by a focus group of 6 university pharmacy students. The questionnaire demonstrated a Cronbach's alpha value of 0.80 and adequate item discrimination capability. Confirmatory factor analysis was performed to assess construct validity, confirming the 5 predefined dimensions. A questionnaire has been developed and validated with high reliability and validity. Its use will help identify areas for improvement in the university education of pharmacy students, ultimately contributing to better use and dispensation of antibiotics and thereby improving antimicrobial resistance.
