Abstract
Background: The objective structured practical examination (OSPE) is used as an assessment tool of laboratory practical sessions. This study described the design and implementation of peer-led mock OSPE for first- and second-year medical students, investigated the perception of the students of the peer-led mock OSPE and the impact of attending the mock OSPE on the performance. Methods: This is a cross-sectional study. Two mock OSPEs were designed and conducted by third-, fourth- and fifth- year medical students for year one and two. Each mock OSPE involved six stations. Thirty-three medical students facilitated the OSPE. The OSPEs were conducted prior to the summative end of block exams. Following the mock OSPEs, an online survey was sent to the participants to assess their satisfaction, quality and benefits of the mock OSPE. The study also evaluated the impact of the mock OSPE on students' performance. Results: Out of 313 first-year students, 279 (89.1%) attended the mock OSPE and out of 298 second-year students, 213 (71.5%) attended. A total of 192 (68.8%) first-year medical students and 102 (47.9%) second-year medical students completed the questionnaire. There was no significant difference between attending and non-attending the mock OSPE in the students' performance in the summative OSPE. The majority of students felt more confident, less anxious, and lowered the levels of stress after attending the mock OSPE. More than half of the students felt that attending the mock OSPE helped in easing the steps, better preparation, provided sufficient orientation, well explained the materials and helped them to learn the concept of the final OSPE. The majority of students found the mock OSPE stimulating. Conclusion: Attending the mock OSPE did not affect the students' performance in the summative OSPE. However, the peer-assessed mock OSPE improved the medical students' confidence and lowered the anxiety associated with OSPE.
