The SPADI is the most frequently evaluated PROM and its measurement properties seem adequate apart from a lack of information regarding its measurement error and content validity .
Dutch users could use either the SDQ or the SST .
In Tamil , Slovene , Spanish and the Danish language s , the evaluated PROMs were not yet of acceptable validity .
None of these PROMs showed strong positive evidence for all measurement properties .
Objective To critically appraise and compare the measurement properties of self-administered patient-reported outcome measures ( PROMs ) focussing on the shoulder , assessing “ activity limitations . ”
Agreement, reliability and validity in 3 shoulder questionnaires in patients with rotator cuff disease
Background Self-report question naires play an important role as outcome measures in shoulder research . Having an estimate of the measurement error of these question naires is of importance when assessing follow-up results after treatment and when planning intervention studies . The aim of this study was to cross-culturally adapt the Norwegian version of the OSS and WORC question naire and examine and compare agreement , reliability and construct validity of the disease-specific shoulder question naire WORC with two commonly used shoulder question naires , SPADI and OSS , in patients with rotator cuff disease . Methods 74 patients with rotator cuff disease were recruited from the outpatient clinic of the Physical Medicine and Rehabilitation Department at Ullevaal University Hospital in Oslo , Norway . A test-retest design was used , and the question naires were filled out by the patients at the clinic , with a one week interval between test administrations . Agreement ( repeatability coefficient ) , reliability ( ICC ) and construct validity were examined and compared for WORC , SPADI and OSS . Results Reliability analysis was restricted to the 55 patients ( 51 ± 10 yrs ) who reported no change between test administrations according to scoring on a global scale . The agreement , reliability and construct validity was moderate for all three question naires with ICC ranging from 0.83 to 0.85 , repeatability coefficient from 16.1 to 19.7 and Spearman rank correlations between total scores from r = 0.57 to 0.69 . There was a lower degree of floor and ceiling effects in SPADI compared to WORC and OSS . Conclusion We conclude that the agreement and reliability of the three shoulder question naires examined , WORC index , SPADI and OSS are acceptable and that differences between scores were small . The Norwegian version of the question naires is acceptable for assessing Norwegian-speaking patients with rotator cuff disease . The moderate agreement and construct validity should be taken into consideration when assessing follow-up results after treatment and in the planning of prospect i ve studies
