  1. Note 1: “History of present illness” is the only criteria with a two-factor solution: one of the two solutions shows low reliability and correlates poorly with the other OSCE scales: it is not included in further analysis
  2. Note 2: One item is a constant: everyone answered correctly, and it is therefore not included in the analysis
  3. Note 3: Dropped subscale, poor initial and final reliability, and unsatisfactory factor solution
  4. Note 4: One item is a constant: everyone answered correctly, and it is therefore not included in the analysis
  5. Note 5: Dropped subscale, poor initial and final reliability, unsatisfactory factor solution
