“…Rasch analysis would also allow the construction of a common metric to facilitate a standardized reporting of OHRQoL using different instruments. Prodinger and colleagues 38 reported in 2016 on a study using exactly this approach. Future studies should seek more uniform and standardized approaches, including using the same domain, dimensions, names, or subscales.…”

Background. Oral health is related to major chronic diseases and contributes to general health. Oral healtherelated quality of life (OHRQoL) is, therefore, an essential part of well-being. Measurement of OHRQoL over the lifetime requires accurate and comparable outcome measures that are suitable for different age groups. The most frequently used instrument for children aged 11 through 14 years is the Child Perceptions Questionnaire (CPQ-11-14). The authors aimed to examine the psychometric properties of the CPQ-11-14 using modern statistical approaches. Methods. The authors carried out a psychometric analysis of 2 population-representative data sets from Germany (N ¼ 2,658) and a randomly selected smaller sample (n ¼ 300) on the basis of the Rasch model. Results. The authors detected a right-skewed distribution of the CPQ-11-14 total scores. The instrument items did not match the level of OHRQoL of the study participants. Moreover, a large number of questionnaire items (range, 51.4%-94.3%) had so-called disordered thresholds, meaning that the answer categories did not work as intended. Unidimensionality was achieved via splitting the CPQ-11-14 into 2 subscales, namely socioemotional and oral symptoms and functioning. Conclusions. Despite its classic validation, the CPQ-11-14 needs adaptions for meaningful clinical use. More items on the better end of the scale are needed to better differentiate between children with higher and lower OHRQoL. Practical Implications. The Rasch model addresses psychometric properties of questionnaires on an item-based level, which were not detected via classic approaches. The results reported by the authors are needed to generate a well-calibrated outcome measure for accurate clinical and public health assessment of OHRQoL.

“…In principle, any number of instruments can be integrated into a common metric as long as they are conceptually equivalent. Examples with more than 2 scales exist and have been published (5,13,20).…”

“…Likewise, the FIM(TM) total scores can be reported on their original range and are therefore considered more accurate. The common metric was designed to range from 0 (complete dependence in ADL) to 100 (complete independence in ADL), oriented at similar research projects (13,17), reflecting minimum and maximum logit estimates derived from the joint analysis.…”

“…The first option would be difficult to achieve, as there are various reasons for the hetero geneity of the assessment tools in use, such as clinical utility and clinic-specific standards. The latter option, in which a common metric for functioning information is developed, to enable comparison and aggregation of information collected with different tools that measure the same concept, is more feasible (5,(11)(12)(13)(14)(15). For this purpose, a Standardized Assessment and Reporting System (StARS) for functioning information, with an ICFbased intervalscaled neutral common metric as core element, would enable clinicians to continue using different assessment tools, while at the same time ena bling the aggregation and comparison of conceptually equivalent information (5,13).…”

In our study we developed a common metric serving as a neutral comparator of two assessment tools which are used for assessing activities of daily living in rehabilitation patients in Switzerland. This common metric enables clinicians to use different established assessment tools assessing the same information, while being able to compare the respective information from those different scales on a larger level e.g. comparisons across clinics using different tools. This study is based on the example of Switzerland, where rehabilitation clinics can choose one of two measurement tools assessing activities of daily living, to report their outcome quality. With the common metric, the results from all the clinics can be compared with each other, no matter what tool was used for the assessment, enabling learning and improvement processes. Objective: Many different assessment tools are used to assess functioning in rehabilitation; this limits the comparability and aggregation of respective data. The aim of this study was to outline the development of an International Classification of Functioning, Disability and Health (ICF)-based interval-scaled common metric for 2 assessment tools assessing activities of daily living: the Functional Independence Measure (FIM TM) and the Extended Barthel Index (EBI), used in Swiss national rehabilitation quality reports. Methods: The conceptual equivalence of the 2 tools was assessed through their linking to the ICF. The Rasch measurement model was then applied to create a common metric including FIM TM and EBI. Subjects: Secondary analysis of a sample of 265 neurological patients from 5 Swiss clinics. Results: ICF linking found conceptual coherency of the tools. An interval-scaled common metric, including FIM TM and EBI, could be established, given fit to the Rasch model in the related analyses. Conclusion: The ICF-based and interval-scaled common metric enables comparison of patients' and clinics' functioning outcomes when different activities of daily living tools are used. The common metric can be included in a Standardized Assessment and Reporting System for functioning information in order to enable data aggregation and comparability.

“…However, if WORQ is to be used as outcome measure longitudinally, valid change scores are needed, and if WORQ scores are to be compared between persons, different health groups, and settings, a summary score based on an interval metric becomes indispensable [31]. However, although the development of WORQ was conceptually based on the model of the ICF and the ICF core sets for vocational rehabilitation (VR), it remains unclear if all 40 items of WORQ and the 13 items of WORQ-BRIEF reflect a single concept of work-related functioning; this assumption is a prerequisite to a reliable interval score [30].…”

The assessment of work-related functioning is a key process in vocational rehabilitation to identify specific domains of disability that can be considered within return to work strategies. The Work Rehabilitation Questionnaire (WORQ) was developed to evaluate work-related functioning based on the International Classification of Functioning, Disability, and Health (ICF) framework and is available in different languages. The aim of this study was to assess the French version of the WORQ using item response theory to further validate the scale. Rasch analysis of WORQ and the WORQ-BRIEF (a brief version of the WORQ) was performed using a calibration sample of 221 persons with musculoskeletal injuries. A four-testlet solution indicated the unidimensionality of WORQ, with no differential item functioning for age, education, physical job demands, and injury severity. Reliability was 0.969 and 0.918 for WORQ and WORQ-BRIEF, respectively. The minimal detectable change was calculated to be 4.2% of its operational range for WORQ and 8.5% for WORQ-BRIEF. Consequently, the French version of WORQ can be considered a good measure of work-related functioning in musculoskeletal conditions. WORQ can be used in rehabilitation practice to comprehensively identify the disability and guide clinical decision making and intervention planning. Further studies are needed to evaluate the psychometric properties of WORQ in other health conditions.
