Research in medical education has been paid more attention than before; however the quality of research reporting has not been comprehensively appraised. To evaluate the methodological and reporting quality of Iranian published medical education articles.Articles describing medical students, residents, fellows or program evaluation were included. Articles related to continuing medical education or faculty development, review articles and reports, and studies considering both medical and nonmedical students were excluded. We searched MEDLINE through PubMed in addition to major Iranian medical education search engines and databases including Scientific Information Database (SID) from March 2003 to March 2008. The Medical Education Research Quality Index (MERSQI) scale and the Consolidated Standards of Reporting Trials (CONSORT 2001) were used for experimental studies and the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) was utilized for observational studies.Ninety five articles were found to be related to the medical education research in Iran including 16 (16.8%) experimental studies. Total MERSQI scores ranged between 3.82 and 13.09 with the mean of 8.39 points. Mean domain scores were highest for data analysis (1.85) and lowest for validity (0.61). The most frequently reported item was background (96%) and the least reported was the study limitations (16%).The quality of published medical education research in Iran seems to be suboptimal.
