*Cumulative odds ratios; odds ratios > 1 indicate a higher probability of assigning a response category involving shorter maximal acceptable waiting times for a vignette.

**A scale score of zero indicates a neutral attitude; positive scores indicate a positive attitude towards waiting lists in health care.
