BackgroundResearch activities undertaken during University studies contribute to preparation of medical students for practice of evidence-based medicine. This study aimed to understand medical students’ experiences, perceived research skills development and satisfaction associated with completion of mandatory research projects.MethodsAn online survey was sent to five cohorts of students (n = 1375) from years 2017–2021 at the completion of their research projects. Univariate analysis was conducted to understand students’ perception of research skills development, followed by linear regression modeling to explore factors influencing satisfaction with their research project. Manifest content analysis employing a framework approach was used to analyse qualitative data from responses to open ended questions.ResultsResponse rate was 42%, with 513 (89%) returned surveys being complete and included in analysis. Whilst 37% of students felt they had requisite research skills before undertaking the research project, 84% reported they had these skills after completing the project (χ2= 8.99, P = 0.02). Mean satisfaction score of the students was 5.0/10 (+/- 2.5, median = 6 (IQR = 3.0–7.0) with 59% of students reporting satisfaction scores higher than the average. Higher satisfaction scores were reported by those who perceived that: research methods and teaching was useful in preparing them for conducting research; the research project helped them acquire new skills; the project resulted in peer-reviewed publication; and, who felt supported by their supervisors. Responses to open ended questions offered important insights into student experience and emphasised the importance of supportive supervisors and the need for a dedicated research block in the busy medical program.ConclusionsThe majority of students reported positive outcomes from the mandatory research project. Student satisfaction can be improved by ensuring supportive research environments and high-quality supervision, and inclusion of dedicated research time in the medical curriculum.Supplementary InformationThe online version contains supplementary material available at 10.1186/s12909-023-04475-y.
