Working mechanism of a multidimensional computerized adaptive test for @entity1295 in XXXX .

@entity1 @entity1295 @entity309
BACKGROUND: This paper demonstrates the mechanism of a multidimensional computerized adaptive test (CAT) to measure @entity1295 in @entity1 with @entity309 ( @entity309 ). A CAT can be used to precisely measure @entity1 -reported outcomes at an individual level as items are consequentially selected based on the @entity1 's previous answers. The item bank of the CAT Fatigue @entity309 has been developed from the @entity1 ' perspective and consists of 196 items pertaining to three @entity1295 dimensions: severity, impact and variability of @entity1295 . METHODS: The CAT Fatigue @entity309 was completed by fifteen @entity1 . To test the CAT's working mechanism, we applied the flowchart-check-method. The adaptive item selection procedure for each @entity1 was checked by the researchers. The estimated @entity1295 levels and the measurement precision per dimension were illustrated with the selected items, answers and flowcharts. RESULTS: The CAT Fatigue @entity309 selected all items in a logical sequence and those items were selected which provided the most information about the @entity1 's individual @entity1295 . Flowcharts further illustrated that the CAT reached a satisfactory measurement precision, with less than 20 items, on the dimensions severity and impact and to somewhat lesser extent also for the dimension variability. @entity1 ' @entity1295 scores varied across the three dimensions; sometimes severity scored highest, other times impact or variability. The CAT's ability to display different @entity1295 experiences can improve communication in daily clinical practice, guide interventions, and facilitate research into possible predictors of @entity1295 . CONCLUSIONS: The results indicate that the CAT Fatigue @entity309 measures precise and comprehensive. Once it is examined in more detail in a consecutive, elaborate validation study, the CAT will be available for implementation in daily clinical practice and for research purposes.
