*Members (N=9) of an international TEP assessed independently whether the domain should (score=3), should maybe (score=2) or should not (score=1) be part of the Quality Improvement Minimum Quality Criteria Set (QI-MQCS). The respondents were instructed that the goal was to identify a minimum number of core domains; n/a: not applicable, the items were developed as a response to panel input.
†Percentage of publications meeting the criterion in psychometric evaluation sample (total N=54 publications, number of observations ranged from 18 to 45 as only the final item version was included in the analysis).
