The concepts of metacognitive refection, refection, and metacognition are distinct but have undergone shifts in meaning as they migrated into medical education. Conceptual clarity is essential to the construction of the knowledge base of medical education and its educational interventions. We conducted a theoretical integrative review across diverse bodies of literature with the goal of understanding what metacognitive refection is. We searched PubMed, Embase, CINAHL, PsychInfo, and Web of Science databases, including all peer-reviewed research articles and theoretical papers as well as book chapters that addressed the topic, with no limitations for date, language, or location. A total of 733 articles were identified and 87 were chosen after careful review and application of exclusion criteria. The work of conceptually and empirically delineating metacognitive reflection has begun. Contributions have been made to root metacognitive refection in the concept of metacognition and moving beyond it to engage in cycles of refection. Other work has underscored its affective component, transformational nature, and contextual factors. Despite this merging of threads to develop a richer conceptualization, a theory of how metacognitive refection works is elusive. Debates address whether metacognition drives refection or vice versa. It has also been suggested that learners evolve along on a continuum from thinking, to task-related refection, to self-refection, and finally to metacognitive refection. Based on prior theory and research, as well as the findings of this review, we propose the following conceptualization: Metacognitive refection involves heightened internal observation, awareness, monitoring, and regulation of our own knowledge, experiences, and emotions by questioning and examining cognition and emotional processes to continually refine and enhance our perspectives and decisions while thoughtfully accounting for context. We argue that metacognitive refection brings a shift in perspective and can support valuable reconceptualization for lifelong learning.
