PURPOSE To conduct a meta-analysis of published studies to determine the predictive validity of the MCAT on medical school performance and medical board licensing examinations. METHOD The authors included all peer-reviewed published studies reporting empirical data on the relationship between MCAT scores and medical school performance or medical board(More)
PURPOSE The use of multisource feedback (MSF) or 360-degree evaluation has become a recognized method of assessing physician performance in practice. The purpose of the present systematic review was to investigate the reliability, generalizability, validity, and feasibility of MSF for the assessment of physicians.

OBJECTIVE Residents must become proficient in a variety of procedures. The practice of learning procedural skills on patients has come under ethical scrutiny, giving rise to the concept of simulation-based medical education. Resident training in a simulated environment allows skill acquisition without compromising patient safety. We assessed the impact of a(More)
BACKGROUND Although the reliability of admission interviews has been improved through the use of objective and structured approaches, there still remains the issue of identifying and measuring relevant attributes or noncognitive domains of interest. In this present study, we use generalizability theory to determine the estimated variance associated with(More)
BACKGROUND A recent randomized trial of patients with primarily anterior circulation intracranial artery stenosis showed that intensive medical therapy was superior to intracranial stenting in preventing recurrent stroke. The rate of stroke recurrence or death in symptomatic intracranial vertebrobasilar stenosis with medical therapy alone may be especially(More)
