Table 5 Validity of the KOOS for the patient group with moderate OA

From: The Dutch version of the knee injury and osteoarthritis outcome score: A validation study

  KOOS Pain KOOS Symptoms KOOS ADL KOOS Sport/Rec KOOS QOL
SF-36 Subscale      
BP 0.63* 0.57 0.71 0.43 0.62
PF 0.72 0.60 0.75* 0.60 0.70
SF 0.36 0.48 0.50 0.05 0.42
RF 0.23 0.32 0.36 0.12 0.26
RE 0.33 0.39 0.41 0.16 0.46
MH 0.23 0.36 0.27 -0.01 0.25
VT 0.37 0.35 0.48 0.05 0.37
GH 0.32 0.22 0.32 0.13 0.29
VAS for pain -0.69* -0.57 -0.69 -0.38 -0.75
  1. Validity is expressed by Spearman correlations between KOOS subscales, SF-36 subscales and VAS-pain. Abbreviations: OA; osteoarthritis, BP, bodily pain; PF, physical function; SF, social function; RF, role limitations because of physical problems; RE, role limitations because of emotional problems; MH, mental health; VT, vitality; GH, general health perception; ADL, Activities of daily living; QoL, Quality of life. In bold: convergente correlations that should be ≥ 0.60, In Italic: divergente correlations that should be ≤ 0.30. All other hypotheses are expected to be between 0.30 and 0.60. Correlations marked by * have to be 0.05 higher than the other convergent correlations.
