“…The Cochin Index was developed at the Cochin Hospital in Paris to assess physical function of the hand in 96 patients with rheumatoid arthritis [26]. The Cochin and Dreiser indices and several other instruments were administered 1 hour apart to 96 patients with OA [27]. The Cochin correlated well with the Dreiser Index (r=0.87) and less with patient perceived handicap reported by VAS (r=0.67), indicating good construct validity (ICCs of 0.96).…”

Accepted outcome measures in randomized controlled trials (RCTs) in osteoarthritis (OA) include patient-reported assessments of physical function and health-related quality of life (HRQOL). Available data can inform treatment decisions when statistically significant changes are viewed in terms of clinically important improvements. Patient-reported outcomes validated in OA include global assessments of pain, disease activity, and disease-specific and generic measures of physical function and HRQOL. Definitions of minimum clinically important differences (MCID) have been derived from RCTs with physical therapy, nonsteroidal anti-inflammatory drugs (NSAIDs), and cyclooxygenase-2 selective agents. Definitions of MCID should serve only as guidelines based on mean changes in a treatment group, and do not necessarily reflect clinically meaningful improvements for an individual patient. They help to interpret data across treatments and patient populations. Definitions of MCID may differ for the type of intervention assessed; additional methodologic issues must be addressed when evaluating nonpharmacologic treatments. Based on RCTs in OA evaluating physical therapy, cyclooxygenase-2 agents, and NSAIDs, the Western Ontario and McMaster Osteoarthritis Index is valid, reliable, sensitive to change, and correlates closely with the generic Medical Outcomes Survey Short-Form 36 measure of HRQOL. When evaluating RCT data, understanding derivation and MCID values of outcome measures facilitates informed therapeutic decisions regarding therapeutic interventions.

“…In the present study, of the 4 PCS components, physical functioning was poorly correlated with bodily pain (r ϭ 0.33), physical role (r ϭ 0.34), and general health perception (r ϭ 0.35). The weak correlation between physical function and pain in SSc has been observed in other illnesses such as RA and knee or hand osteoarthritis (21)(22)(23)43).…”

Objective. To assess the construct validity of the Cochin Hand Function Scale (CHFS) and the relevance of using aggregate scores for the scleroderma Health Assessment Questionnaire (sHAQ) and Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) in systemic sclerosis (SSc). Methods. We evaluated 50 patients with SSc (mean ؎ SD age and disease duration 54 ؎ 12 years and 9 ؎ 8 years, respectively), of which 26 had limited cutaneous SSc (lcSSc) and 23 diffuse SSc (dSSc). Quality of life was assessed by the SF-36, global disability by the Health Assessment Questionnaire (HAQ) and sHAQ, and hand disability by the CHFS. Construct validity was assessed by convergent and divergent validity (Spearman's rank correlation coefficient) and factor analysis. Results. The CHFS had good construct validity and its total score explained 75% of the variance of the HAQ. The HAQ had better construct validity than the aggregate sHAQ and their scores correlated well (r ‫؍‬ 0.88). The aggregate sHAQ was no better than the HAQ in discriminating between lcSSc and dSSc. SF-36 physical and mental components had acceptable convergent and divergent validity. Factor analysis of the 8 subscales extracted 3 factors explaining 72% of the variance, which differed from the a priori stratification with physical and mental subscales extracted in the same factor. Conclusion. In patients with SSc, the CHFS has good construct validity, the HAQ should be preferred over the aggregate sHAQ for assessing physical functioning, and use of SF-36 physical and mental components aggregate scores is questionable.
