Questionnaire abbrevations (abb): the same abbrevations as in Table 3 are used.
Internal consistency: Considered as good when Chronbach’s Alpha ≥ 0.80 or Rasch analysis is good, acceptable when Chronbach’s Alpha 0.80-0.70 or
Rasch shows some problems, inadequate when Chronbach’s Alpha < 0.70, only inter-item correlations or inadequate statistical analyses. 14
Test-retest reliability: Considered as good when intraclass correlation coefficients (ICC) ≥ 0.80, Kappa ≥ 0.75, and/or good evidence for minimal detectable
change (MDC) or coefficient of variation (CV), acceptable when ICC 0.80-0.40 and/or Kappa 0.75-0.40, and inadequate when ICC and/or Kappa < 0.40, and
when Pearson statistics is used. 14
External construct validity: Considered as good when high convergent correlations with r ≥ 0.60, moderate when r 0.60-0.30, and weak when r <0.30. 14
Discriminant validity: Considered as good when evidence meets high standard such as area under receiver operating curves or group differences by means
or %, acceptable when adequate standard, and inadequate or low when evidence do not support the discriminant abilities, or none/few analyses have been
carried out. 14
Responsiveness (sensitivity to change): Considered as good when evidence is strong, in the expected direction, supported by patient or clinical evidence,
and/or effect size statistics good (SRM ≥ 0.80), acceptable when moderate effect size (SRM 0.40-0.80), conflicting evidence or only used
associations/correlations, inadequate or weak evidence when SRM< 0.40, when evidence is based solely on statistical significance, or inadequate statistical
analyses. 14
