Item and scale characteristics, internal consistency reliability, and item-total correlations.

†The items shared the same subject ‘During my residency in [medical specialty], my attending generally…’ (residents' evaluation of faculty) or ‘In my role as an attending internist/faculty, I generally…’ (faculty self-evaluation).‡Factor loadings in parentheses were obtained using the polychoric correlation matrix as input for the principal components analysis. Similar results but with even higher factor loadings were also obtained when we applied maximum likelihood as the factor estimation technique.§Total variance explained by all 5 domains of teaching qualities: 73.08% among residents and 66.39% among facultyaThe item L3 also loads (0.56) on the scale ‘Communication of goals’ in the self-evaluation.bThe item F1 also loads (0.70) on the scale ‘Professional attitude and behavior towards residents’ in the self-evaluation.Cronbach's alpha for all 23 items combined: 0.95 on the resident evaluation (0.96 when aggregated across faculty) and 0.91 on the self-evaluation.
