Four related concepts, each with slightly different implications for psychiatric training, have now been introduced: research literacy, critical appraisal skills, evidence-based medicine, and practice-based learning. The following working definitions might be considered. Research literacy, as articulated in the IOM report, entails the ability to assimilate emerging theoretical knowledge about biology and empirical information relevant to a given set of symptoms and corresponding risk factors or treatments (
+1). Critical appraisal enables the application of certain rules of evidence and the laws of logic to clinical, investigative and published data and information in order to evaluate their validity, reliability, credibility and utility (
+4). Skills in critical appraisal should assist readers to identify the validity of scientific design and strength of results, and these are being actively taught as one component of evidence-based medicine in many medical schools (
+5—
+9). Evidence-based medicine is a scholarly field—a larger process that also requires an ability to ask focused questions on diagnosis, prognosis, interventions, ethics, and economics beginning with analysis of a clinical situation, retrieval of best evidence, and, crucially, integration of that evidence into clinical care. As such, this field necessarily involves an understanding of epidemiology, quantitative issues (e.g., statistics pertaining to relative risk reduction, absolute risk reduction, confidence intervals, etc). This is a systematic process, in that it is asserted, can be taught and practiced by clinicians at all levels of seniority, and can promote teamwork and self-directed and life-long learning (
+10). Practice-based learning as a domain of basic competence for the modern physician incorporates skills of review, analysis, and assimilation of scientific evidence (
+3). These linked endeavors in residency training serve to affirm, anchor, and advance the scientific basis of the field of psychiatry.
