title: Is there an association between study materials and scores on the American Board of Orthopaedic Surgeons Part 1 examination?
abstract: BACKGROUND
  Previous studies have shown that certain orthopaedic in-training examination scores can be used to identify which residents may be at risk for failing the American Board of Orthopaedic Surgeons (ABOS) Part 1 examination. However, no studies have examined how study resources may affect residents' ABOS Part 1 scores. The goal of this study is to determine which review sources or review courses, if any, are associated with improved ABOS Part 1 scores.
  
  
  METHODS
  A survey was sent to 221 of the 865 examinees who took the ABOS Part 1 examination in 2012. The questions inquired the respondents how well they performed on previous orthopaedic in-training examinations and ABOS Part 1, along with the study sources they most commonly used, review courses they attended, and resources they would recommended if they were to retake ABOS Part 1 examination.
  
  
  RESULTS
  Overall, 118 of the 221 (53%) survey recipients completed the survey. Six (5%) of the respondents failed ABOS Part 1 examination. Orthobullets and the American Academy of Orthopaedic Surgeons self-assessment examinations were recommended as the primary study source significantly more (p < 0.01) than most other resources, but there was no significant association between study source and passing ABOS Part 1 or scoring in a certain percentile on ABOS Part 1. Similarly, there were no associations between attending a review course and either passing or scoring in a certain percentile for ABOS Part 1. Half of the respondents who failed ABOS Part 1 attended multiple review courses.
  
  
  CONCLUSIONS
  There does not appear to be an association between improved ABOS Part 1 scores and orthopedic study materials or review courses. Further research into the value of certain educational modalities should be conducted to determine the best ways to educate orthopedic residents and determine the value of some of these commonly used orthopedic review modalities.
