Abstract

Objective: This study aimed to develop and validate a questionnaire designed to assess knowledge and behaviors regarding antibiotic use across students from non-healthcare disciplines. Subjects and Methods: A cross-sectional descriptive study was conducted to develop and validate a questionnaire, focusing on its content validity, internal consistency, and construct validity. Results: The initial questionnaire comprised 24 questions derived from relevant reference materials. Content validation was achieved through feedback and suggestions from a panel of experts on two separate occasions, with pilot testing implemented between these two assessments. A total of 138 students participated in the survey to evaluate internal consistency and construct validity. The final version of the questionnaire was streamlined to 11 questions, categorized into four groups: Group 1 - General Knowledge about Antibiotics, Group 2 – Misunderstandings in Antibiotic Use, Group 3 - Antibiotic Resistance, and Group 4 - Behavior Regarding Antibiotic Use. The Cronbach's alpha values for the finalized questionnaire across the four groups were 0.69, 0.75, 0.64, and 0.73, respectively. Conclusion: The questionnaire, consisting of 11 questions, was developed and validated, demonstrating good content validity, internal consistency, and construct validity.
