Abstract
Introduction: In Competency-Based Medical Education, formative assessments are integrated throughout the curriculum to offer continuous feedback, promoting self-regulatory learning and helping learners to identify the areas for improvement. Peer and self-assessment play a crucial role in CBME by fostering collaboration, self-reflection, critical thinking, and professionalism. Assess the reliability of peer and self-assessment across different learning domains in a CBME framework for formative assessment.
Methods: This observational study, conducted from January 2024 to December 2024 at a Government Tertiary Care Hospital, involved a universal sampling method with 100 second-year medical students. Assessments addressed knowledge through assignments, psychomotor skills through vitals and systemic exams, and affective skills through communication and interpersonal abilities. Evaluations by peers, self, and faculty were conducted using an internally validated tool, with anonymity maintained throughout.
Results: Participants were aged 18–21 with a male-to-female ratio of 1:1.2. ANOVA tests showed no significant difference in knowledge scores between self, peer, and faculty assessments (ICC=0.708; P=0.106). Significant differences were found in psychomotor (P=0.001; ICC=0.483) and attitude (P=0.001; ICC=0.234) domains, with students and peers overestimating or underestimating performance. Bland–Altman plots confirmed good agreement for knowledge, moderate for psychomotor, and poor for attitude between self, peer, and faculty ratings.
Conclusion: The study found moderate reliability in the knowledge domain but poor to no reliability in the attitude and psychomotor domains, with self and peer assessments tending to overestimate performance. These findings underscore the need for more training and structured assessment strategies to enhance the accuracy and consistency of self- and peer-assessment in medical education.
