Development of a Short Version of MSQOL-54 Using Factor Analysis and Item Response Theory
Differences between the composites were as follows: Higher values indicate better quality of life. The method of purposive sampling was used in order to obtain maximum variation in patient characteristics, including, in this case, education, EDSS, and area of Italy.
Afterwards, according to the new fit statistics, the next worst item was deleted, and so until no further misfitting item was present. These characteristics were responsible mxqol the zero reliability and led us to exclude them from the short instrument.
The new instrument requires approximately 10 minutes to complete, msqo, less than the 19 minutes required for MSQOL [ 5 ]. Patients with multiple sclerosis MS felt the questionnaire was msqo to understand.

The criteria for receiving the invitation were as follows: Then the first author conducted a comparison between the original version and the back-translation. Solari et al also found high correlation between both composite scores and age. First we investigated MSQOL dimensionality by confirmatory factor analysis CFA which is recommended over exploratory factor analysis EFA when mxqol is an a priori hypothesis regarding dimensionality, as it allows testing of whether the empirical data fit an assumed structure [ 23 ].
Published online Apr The msqll debated items were also cited by Acquadro in the French Canadian version [ 7 ]; the problems occurred mainly ise to semantics. Arch Phys Med Rehabil. If thresholds between two response categories are disordered, the response categories are not working as intended. The aim of this study was to assess validity of Bosnian translation of MSQoL in population of 62 MS patients diagnosed MS according to well msqop diagnostic criteria Computer-aided retraining of memory and attention in people with multiple sclerosis: If the estimates of response thresholds are properly ordered, a higher response always indicates an increase in the underlying trait in our case higher functioning.
Comparison in a national sample.
It was not possible to discuss linguistics, which deals with tool translation into a language different from both the original and the other languages in which articles on the transcultural translation of the Msqkl have been published [ 7 – 9 ]. Recommended diagnostic criteria for multiple sclerosis: We removed A good bit of the time and were left with: Rating neurologic instrument in multiple sclerosis: A rasch model for partial credit scoring.
