Abstract
The Greek versions of WOMAC LK 31 and Lequesne indices were administered to 97 outpatients with OA Internal consistency reliability was assessed by Cronbach’s alpha and item–scale correlations Test–retest reliability was examined with intraclass correlations Patients were also asked to complete the Short Form 36 SF36 and a Visual Analog Scale capturing strength of pain in order to assess construct validity Additional demographic and clinical data were also recorded to evaluate further associationsCronbach’s alpha values of the WOMAC ranged between 092 and 098 for hip and 089–097 for knee OA The respective values for Lequesne were 063–074 and 074–080 Item–scale correlations confirmed the superiority of WOMAC with respect to internal consistency reliability Intraclass correlations were 079–097 and 057–098 for hip and 086–097 and 082–097 for knee OA for WOMAC and Lequesne respectively The two indices showed high correlations with comparable subscales of SF36 and the Visual Analog Scale Significant relationships were identified for age body mass index duration of disease duration of stiffness and radiographic classification
