  1. For interpretation of “+” and “−” for each property: Internal reliability: “+” Cronbach’s ɑ or ICC ≥ 0.70; “−” Cronbach’s ɑ or ICC < 0.70;
  2. Test/retest method: “+” ICC ≥ 0.70 or Pearson correlation coefficient/ Spearman rank correlation coefficient ≥ 0.80; “−” ICC < 0.70 or Pearson correlation coefficient/Spearman rank correlation coefficient < 0.80;
  3. Interrater reliability: “+” ICC ≥ 0.70 or Pearson correlation coefficient/ Spearman rank correlation coefficient ≥ 0.80; “−” ICC < 0.70 or Pearson correlation coefficient/Spearman rank correlation coefficient < 0.80;
  4. Content validity: “+” The content of the assessment instrument is adequate, comprehensive, questions and tasks chosen to adequately reflect the content to be evaluated; “−” Not all selected questions and tasks reflect the content, content is not relevant, comprehensive;
  5. Criterion validity: “+” Significant and stable relation between measurement and another instrument (r ≥ 0.70) or with start/end measurement; “−” Poor measurement correlation with another instrument (r < 0.70) or start / end measurement;
  6. Structural validity: “+” Correlation with instruments measuring the same ≥ 0.50 or correlation higher for unrelated elements in the instrument than for unrelated ones; “−” Correlation with instruments measuring the same < 0.50 or correlation with related elements in the instrument is lower than unrelated ones;
  7. Responsiveness: “+” Able to detect clinically significant changes over time; “−” Cannot detect clinically significant changes over time
  8. *Except Cognitive scale
