Knowledge of and Attitudes Toward Clinical Trials: A Questionnaire-Based Study of 179 Male Third- and Fourth-Year PharmD Undergraduates from Riyadh, Saudi Arabia.

BACKGROUND Clinical Trials (CTs) are essential for the formation of a new medicine. This questionnaire-based study included 179 male third- and fourth-year PharmD undergraduate students from Riyadh, Saudi Arabia, between 18 and 23 years of age, was conducted in 2022, and aimed to evaluate student knowledge and attitudes toward CTs. MATERIAL AND METHODS A cross-sectional study was conducted using self-administered questionnaires. The data was collected using convenience sampling. Part 1 of the study collected demographics, with 6 items; part 2 measured knowledge about CTs (9 items); part 3 measured attitudes (5 items) measured on a 5-point Likert scale. A score of 1 was given for correct, and a score of 0 for each incorrect response. Multiple linear regression was used to evaluate the determinants of knowledge and attitudes about CTs. RESULTS A total of 108 (60.3%) undergraduates reported having heard about CTs, 15% of undergraduates had heard about institutional review boards, while 74.3% of the undergraduates believed that CTs have direct benefits to society. The mean knowledge score of the CTs among the students was 5.75±2.32 (median 6.00), while the mean attitude score of CTs was 16.45±4.56 (median 16.00). However, the results of the simple regression model revealed that age, year of study, and chronic disease status were not predictors of the knowledge and attitude score (P>0.05). CONCLUSIONS This study indicated that half of undergraduates were aware of CTs, were knowledgeable, and showed positive attitudes. Furthermore, the study identified potential misunderstandings about the benefits of CTs.
