Notes: *Based on a modified version of the quality criteria developed by Terwee et al.23 aCronbach’s alpha: + if 0.7–0.95; - if (< 0.7 or >0.95). ^bPearson’s correlation coefficient (r): + if r≥0.70; - if r<0.70. ^cContent validity: + if reported. N/A: No information available to establish rating; ±, conflicting results in studies or inconsistent results across subscales? questionable/not rated.
