title: [Validation of the computerized adaptive assessment procedure RehaCAT related to functional and mental strain in a sample of rehabilitation patient suffering from musculoskeletal diseases].
abstract: The Rasch-based, computerized adaptive assessment procedure RehaCAT allows to assess the ICF-oriented dimensions "activities in daily living", "functionality upper extremities" and "functionality lower extremities" as well as "depression" economically and reliably in orthopaedic rehabilitation patients. This validation study aimed at analyzing the multivariate association of the RehaCAT dimensions with the commonly applied ODI, SF-12 and HADS-D assessment scales in a sample of rehabilitation patient suffering from musculoskeletal diseases (spine disease: 58,7%). By means of structural equation modeling high convergent and divergent validity of the RehaCAT dimensions could be proven in a sample of N=184 rehabilitation patients (71,2% inpatient and 28,8% outpatient). In the resulting model between 41% (functionality upper extremities) and 76% (activities in daily living) of the RehaCAT dimensions could be explained mainly by the theoretical assumed predictor constructs. Because of its psychometric foundation, economy and validity, the RehaCAT provides an optimal basis to assess central ICF-oriented constructs in orthopaedic rehabilitation.
