Randomized Controlled TrialCan student self-ratings be compared with peer ratings? A study of measurement invariance of multisource feedback.
Measurement invariance is a prerequisite for comparing measurement scores from different groups. In medical education, multi-source feedback (MSF) is utilized to assess core competencies, including the professionalism. However, little attention has been paid to the measurement invariance of assessment instruments; that is, whether an instrument holds the same meaning across different rater groups. ⋯ In addition, same factor structure and similar factor loadings and intercepts of NTU P-MSF scores between both groups indicate that NTU P-MSF scores had configural, metric, and scalar invariance. Thus, students' self-assessments and peer assessments can be compared in terms of the constructs of NTU P-MSF scores, change in NTU P-MSF scores, and its factor scores. This study demonstrates how to investigate the measurement invariance of a professionalism MSF and contributes to the discussion on self- and peer assessment in medical education.
