Dataset related to articles "Assessing measurement invariance of MSQOL-54 across Italian and English versions" & "Viability of a MSQOL-54 general health-related quality of life score using bifactor model" & "Applying multidimensional computerized adaptive testing to the MSQOL-54: a simulation study"

The present project is part of an international collaborative initiative of Italian and Australian researchers who set up and share a unique international MSQOL-54 database, in order to develop a computerized adaptive version of the MSQOL-54. The data originated from different datasets collected with the English and Italian versions of MSQOL-54 within ongoing or completed research projects carried out in Australia and Italy. The data support the findings of the following studies: "Assessing measurement invariance of MSQOL-54 across Italian and English versions", "Viability of a MSQOL-54 general health-related quality of life score using bifactor model" and "Applying multidimensional computerized adaptive testing to the MSQOL-54: a simulation study". They include demographic and clinical data, and items of the MSQOL-54 questionnaire.
