Note.
°
= internal consistency for static short form measures is reported as Cronbach’s alpha and for computer adaptive tests is reported as average standard error-based reliability (i.e., an item response theory-based reliability estimate);
*
Test-retest reliability is measured by the intraclass correlation coefficient (ICC; criterion ≥ 0.70)
