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)
BACKGROUND Although there is no clear consensus about the process of screening for developmental dysplasia of the hip (DDH), there are six common risk factors associated with DDH in patients less than 6 months of age (breech presentation, sex, family history, first-born, side of hip, and mode of delivery). METHODS A meta-analysis of published studies was(More)
BACKGROUND The introduction of noninvasive laparoscopic surgery has raised concerns about appropriate teaching techniques for medical students considering surgery as a specialization. The principal aim of this study was to determine the effect, between the sexes, of cognitive imaging as a teaching method in the context of learning a surgical technique. (More)
BACKGROUND There is increasing interest in using simulators for laparoscopic surgery training, and simulators have rapidly become an integral part of surgical education. METHODS We searched MEDLINE, EMBASE, Cochrane Library, and Google Scholar for randomized controlled studies that compared the use of different types of simulators. The inclusion criteria(More)
Traditionally, surgical and procedural apprenticeship has been an assumed activity of students, without a formal educational context. With increasing barriers to patient and operating room access such as shorter work week hours for residents, and operating room and endoscopy time at a premium, alternate strategies to maximizing procedural skill development(More)
BACKGROUND Surgical trainees develop surgical skills using various techniques, with simulators providing a safe learning environment. Fracture fixation is the most common procedure in orthopaedic surgery, and residents may benefit from simulated fracture fixation. The performance of residents on a virtual simulator that allows them to practice the surgical(More)
As opposed to the problem-based approach of dealing with specific at-risk behaviors, the objective of the self-reported Youth Resiliency: Assessing Developmental Strengths questionnaire is to provide a statistically sound and research-based approach to understanding the factors that contribute to the development of adolescent resiliency. The study of(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. METHOD The authors searched the EMBASE,(More)
BACKGROUND Medical education in Saudi Arabia is facing multiple challenges, including the rapid increase in the number of medical schools over a short period of time, the influx of foreign medical graduates to work in Saudi Arabia, the award of scholarships to hundreds of students to study medicine in various countries, and the absence of published national(More)
BACKGROUND To investigate the predictive validity of the Medical College Admission Test (MCAT) for clinical reasoning skills upon completion of medical school. METHOD A total of 597 students (295 males, 49.4%; 302 females, 50.6%) participated from 1991 to 1999. Stepwise multiple regressions of the MCAT and premedical school GPA (independent variables) on(More)
