National Board Of Medical Examiners Part Research Articles

Content bias in the neoplastic-related items of the National Board of Medical Examiners Part II Examination.

The Education Evaluation Committee of the American Association for Cancer Education (AACE) attempted to employ the neoplastic-related items from the National Board of Medical Examiners (NBME) Part II examination in a study correlating program characteristics at various medical schools with performance on the neoplastic-related items. All questions on the September, 1977 and April, 1978 NBME Part II examinations were reviewed by board certified medical oncologists who found an approximate 20% discordance between the AACE and NBME classifications. Content analysis of the neoplastic-related items disclosed a preponderance of questions related to gynecologic cancer with few questions concerning the major solid tumors: lung, breast and colorectal cancer. In addition, virtually no questions related to the psychologic impact of cancer or to the therapy of cancer were asked. We conclude that the use of item by item performance scores from the neoplastic-related items is inadequate for program analysis due to disagreements over what constitutes such an item and to content bias in the agreed upon items. We propose a coding system that may allow the results from current NBME examinations to be used in program evaluation.

Use of NBME examinations to assess retention of basic science knowledge.

About 10 years ago results of the National Board of Medical Examiners (NBME) "Minitest," comprised of samples of questions from NBME Part I and Part II tests, indicated that the change in performance in the total basic science examinations would be minimal between the second and fourth years of medical school. By inserting samples of Part I basic science questions into Part II, large scale tests could be made of the change in performance. In two pilot projects, in a longitudinal study of the same students at a two-year interval, in a cross-sectional study of two groups of students at the same time, and in a comparison of performance of basic science questions in the Federation Licensing Examination (FLEX), the prediction of the minitest results was sustained. Overall performance on all basic science questions decreased only a little. However, the changes in the individual disciplines ranged from a consistent improvement in pathology to a substantial decrease in biochemistry. Pharmacology and behavioral sciences fluctuated between small increases and decreases. Physiology, microbiology, and anatomy decreased consistently, but not as much as biochemistry.

Effectiveness of an international health elective as measured by NBME Part II.

A total of 434 third- and fourth- year medical students from 80 U.S. medical schools participate between 1968 and 1974 in Yugoslav or Israeli international fellowship programs sponsored by the Association of American Medical Colleges and the U.S. Public Health Service. Subsequently, the scores of these fellowship student on Part II of the examinations of the National Board of Medical Examiners (NBME) were compared with the scores of rejected applicants and with the national average to determine the cognitive impact of the fellowship experience on the participants. The results show that the international fellows scored significantly higher than the rejected applicants and the national average in only the preventive medicine/public health portion of the examination. The conclusion is drawn that the fellowship programs enhanced the participants' knowledge of preventive medicine and public health.
