Health Literacy Questionnaire (average ± SD)a

Need for Cognition NRS 0–10 (average ± SD, range)b
 Average score of 3 items, 0–10 7.5 ± 2.1, 2–10
  1. NRS numerical rating scale
  2. ahigher score signifies better health literacy
  3. bhigher score signifies greater need for cognition (which is indicative of a tendency to enjoy effortful cognitive activities)
