“…Similar to other culturally validated measures (27), test-retest reliability assessed by ICC was good for the 3 subscales of WOMAC (all around 0.8), indicating a stable response in Chinese patients with OA of the knee. Given the 7-12 day interval between test and retest, and the dynamic nature of symptom severity in knee OA, which can fluctuate even within a 24-hour period (28), the ICC values are very good.…”

Objective. To establish the reliability, validity, and sensitivity to change of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) among Chinese subjects with osteoarthritis (OA) of the knee, living in mainland China. Methods. A multicenter, randomized, double-blind, placebo-controlled, parallel-group study was conducted for validation of the electronic personal digital assistant version of the WOMAC Numerical Rating Scale (NRS) 3.1 Index in China. A total of 287 subjects with OA of the knee were randomized to receive either meloxicam (15 mg) or placebo. Psychometric properties of the WOMAC were evaluated by estimating the reliability, validity, and sensitivity to change. Equivalence of the electronic version was also compared with the paper version. Results. Intraclass correlation coefficients for the WOMAC pain, stiffness, and physical function subscales were 0.81, 0.76, and 0.85, respectively, indicating good test-retest reliability. Similarly, internal consistency was strong (Cronbach's alpha for the 3 WOMAC subscales was 0.84, 0.86, and 0.96, respectively). Pearson's correlation coefficients for WOMAC pain and Short Form 36 health survey (SF-36) bodily pain, as well as WOMAC physical function and SF-36 physical functioning domains were >0.4, indicating convergent validity, whereas the coefficients for all 3 WOMAC domains with SF-36 mental health and mental health component scores were <0.4, indicating divergent validity. There was strong discriminant validity between healthy volunteers and OA patients. The effect sizes of change from baseline to week 12 in WOMAC subscale scores were large, demonstrating sensitivity to change. Equivalence between paper and electronic versions was very high. Conclusion. The culturally and linguistically validated Chinese version of the WOMAC NRS 3.1 for mainland China is psychometrically robust in its validity, reliability, and sensitivity to change for patients with OA of the knee.

“…Similar studies demonstrated serious disability in their study populations with total Lequesne scores that ranged from 10.51 to 13.67 (11,14,17,18). In our study, the worst score for the Lequesne index was in the ADL domain; this was also reported in the study by Konstantinidis et al (11).…”

“…Before rehabilitation, our results showed that the Lequesne ADL domain was most significantly correlated with the SF-36 PF domain; however, Konstantinidis et al (11) found that the strongest significant correlation existed between the Lequesne ADL domain and the SF-36 SF domain. The correlations among all other subscales in the present study were significant and negative, whereas in the aforementioned study, the correlations among the other subscales were also negative but not statistically significant.…”

“…The other four domains, vitality, social functioning, emotional role, and mental health, evaluate mental health. As there is no total score, each domain is analysed individually and is scored from 0 to 100, where a lower score correlates with a lower health status (7,11,12).…”

Objective. To conduct a systematic review of the measurement properties of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and to evaluate the quality of WOMAC measurement studies using COSMIN (Consensus-Based Standards for the Selection of Health Measurement Instruments) criteria. Methods. A search was conducted in the MEDLINE, CINAHL, Embase, PsycINFO, Scopus, and SPORTDiscus databases through September 2013. Data that assessed the WOMAC measurement model, reliability, validity, respondent burden, and equivalence across methods of administration were extracted. Overall study quality was rated following COSMIN criteria. Results. A total of 76 articles from 22 countries were included. Internal consistency reliability was consistently high (>0.90) for the function scale and acceptable (>0.70) for the pain and stiffness scales. Test-retest reliability was acceptable. Score equivalence was demonstrated across paper and electronic methods of data collection. Floor and ceiling effects were low except for notable (24 -38%) proportions of patients achieving the best possible scores on the pain and stiffness scales 1-23 years after arthroplasty. Five exploratory factor analyses did not support a measurement model in which the pain and function items were distinct. Correlations between the WOMAC pain and function scales were high (median 0.79). The WOMAC pain and function scales had similar correlations with other pain measures, and therefore the WOMAC pain scale did not show divergent validity. COSMIN criteria were not fully met in most studies. Conclusion. The WOMAC scales were reliable, but its pain scale was highly related to physical function. Further research into joint-specific pain measures that have broader content validity is needed. INTRODUCTIONThe Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) has been used in research for more than 25 years (1,2). Available in more than 80 language versions and measuring 3 domains (pain, stiffness, and function) viewed as central to the assessment of patientreported outcomes (PROs) in osteoarthritis (OA), the WOMAC has been recommended for use in clinical trials (3,4) and studied in more than 1,000 peer-reviewed articles.A comprehensive review of the WOMAC measurement properties was conducted in 2001 (5), and the WOMAC has been included in subsequent reviews of outcome measures used in OA (6 -9). However, much of the WOMAC measurement literature published since 2001 has not been cited in these reviews. In addition, the reviews have not examined key WOMAC measurement issues in depth, such as the relationship between its pain and function scales.This systematic review provides an updated summary of the literature on the WOMAC measurement properties in relation to criteria proposed by the Scientific Advisory Committee of the Medical Outcomes Trust (MOT) for evaluating the measurement properties of PRO instruments (10). It also evaluates the overall methodologic quality of WOMAC measurement studies using the COSMIN (Consensus-Ba...

Abstract: Our findings, in samples of knee and hip OA patients, indicate that the WOMAC index demonstrates better internal consistency reliability than the Lequesne counterpart, as well as equivalent test-retest reliability and construct validity.
