IntroductionSelf-efficacy is a theoretically and empirically robust motivation belief that has been shown to play an important role in the learning and development of new skills and knowledge. In this article, we critically review research on the self-efficacy beliefs of medical students, with a goal to evaluate the existing research and to strengthen future work. In particular, we sought to describe the state of research on medical student self-efficacy and to critically examine the conceptualization and measurement of the construct. Finally, we aimed to provide directions for future self-efficacy research.MethodsWe critically reviewed 74 published articles that included measures of self-efficacy beliefs of medical students.ResultsOur review showed that (a) research on the self-efficacy beliefs of medical students is growing and is becoming increasingly international, and (b) that nearly half (46%) of self-efficacy measures showed conceptual and operational flaws.DiscussionOur critical review of 74 research studies on self-efficacy of medical students found that although research in the field is increasing, nearly half of measures labelled as self-efficacy were incongruent with the conceptual guidelines set by self-efficacy experts. We provide five suggestions for future research on the self-efficacy of medical students.Electronic supplementary materialThe online version of this article (10.1007/s40037-018-0411-3) contains supplementary material, which is available to authorized users.
The identified trials provide only low quality evidence about the effects of feeding preterm infants with protein hydrolysate versus standard formula. The existing data did not support conclusions that feeding with protein hydrolysate affects the risk of feed intolerance or necrotising enterocolitis. Further large, pragmatic trials are needed to provide more reliable and precise estimates of effectiveness and cost-effectiveness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
