Background:
To assess resources and self-management skills the generic questionnaire FERUS was developed by Jack (2007) and validated and standardized in a sample of psychosomatic patients and of healthy people. The aim of this study was the psychometric review of the FERUS with a sample of patients with Multiple Sclerosis (MS).
Methods:
The dimensional structure identified by Jack was replicated in an exploratory factor analyses as well as tested in a confirmatory factor analyses and the discrimination ability of the scales was examined.
Results:
Jack's results of the exploratory factor analyses and scale analyses were replicated essentially. After elimination of non-theory-compliant items, differentiation of the construct "motivation for change" and insertion of a second-order construct "self-management skills" a good confirmatorical model fit could be achieved.
Conclusion:
The FERUS can be used for MS patients. The consideration of optimization proposals allows higher construct validity and a more economical use of FERUS.
