title: An assessment of the methodologic quality of medical education research studies published in The American Journal of Surgery.
abstract: BACKGROUND
  This study examined the methodologic quality of medical education research published in The American Journal of Surgery (AJS) relative to other journals and in AJS itself over time.
  
  
  METHODS
  Medical Education Research Study Quality Instrument (MERSQI) scores were determined for 198 education studies published in 2003 in 13 peer-reviewed journals including AJS and all 38 AJS education studies published in 2007.
  
  
  RESULTS
  In 2003, the mean (standard deviation) MERSQI scores of AJS studies were 11.03 (2.12) compared with 9.83 (2.37) for studies published in the other 12 journals (P = .03). AJS studies received higher scores for response rate (P < .001) and content validity (P = .03) than other journals. The mean MERSQI scores among AJS studies remained constant between 2003 and 2007 (12.03 [2.35] vs 11.03 [2.12], P = .13).
  
  
  CONCLUSIONS
  Education studies published in AJS compared favorably with those published in other journals, and this quality was maintained over time. Nonetheless, there is room for improvement with respect to study designs and outcome assessment.
