Practice analysis: a basis for content validity for american board of radiology examinations in diagnostic radiology.
The ABR performs practice analysis every 3 years, according to its strategic plan, in an effort to strengthen the content validity of its qualifying and certifying examinations as well as its maintenance of certification examinations. A nationwide survey of diagnostic radiologists was conducted in July 2010 for the purpose of determining the critically important and frequently performed activities in 12 clinical categories. The survey instrument was distributed electronically to 17,721 members of the ACR, with a unique identification code for each individual. A 5-point scale was established for both frequency and importance variables. The frequency scale ranged from 1 to 5 as follows: 1 = not applicable, 2 = occasionally, 3 = monthly, 4 = weekly, and 5 = daily. The scale for importance also ranged from 1 to 5: 1 = not applicable, 2 = not important, 3 = somewhat important, 4 = important, and 5 = essential. A total of 2,909 diagnostic radiologists (19.32%) participated. Of these, 2,233 (76.76%) indicated that they spent ≥50% of their time in clinical practice. Because of its brevity of the list of the activities, results for the gastrointestinal category are presented in this article. The list of activities weighted according to importance and frequency is presented in this article and, as illustrated, could become the foundation for developing a more detailed blueprint for the gastrointestinal category certifying examinations in diagnostic radiology. Findings on demographic information are also presented.
