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 . ”
The responsiveness of the Shoulder Disability Questionnaire
Objective —To evaluate the responsiveness of the Shoulder Disability Question naire ( SDQ ) . Methods —The study was conducted within the framework of an observational study on shoulder disorders in primary care . After first presentation of their complaints to the general practitioner and after one and six months , participants completed the SDQ , a single question on functional status ( FSQ ) , and an ordinal 11 point scale for the severity of pain ( PSS ) . Responsiveness of the SDQ was evaluated compared with that of the FSQ and PSS , by calculating responsiveness ratios and by plotting receiver operating characteristic ( ROC ) curves . Recovery according to the patient was used as an external criterion for clinical ly relevant improvement ( complete recovery or much improved on a six point Likert scale was denoted as clinical ly relevant improvement ) . Results —A total of 349 consecutive patients with shoulder disorders were enrolled in the observational study . Response rates ranged between 96 % and 89 % . Responsiveness ratios were slightly higher for the PSS compared with the SDQ ( 2.53 versus 2.22 at one month , 2.24 versus 1.89 at six months ) . The area under the ROC curve was 0.84 for both the SDQ and the PSS , and 0.72 for the FSQ . Conclusion —The results of this study confirm the responsiveness of the SDQ , making it a useful instrument to assess functional disability in longitudinal studies
