[Concept and measurement of need for rehabilitation--framework for a multidimensional investigational approach]

As before the concept and content regarding the need for rehabilitation have still not been sufficiently clarified. In particular, an operationalization of the underlying parameters, as the basis for their measurement is absent. Some exemplary research concepts have been introduced and their methodological implications have been put out. Resulting from this, up till now, in the most developed model, determining the need for rehabilitation has been developed as a latent multi-dimensional variable. A framework, as a starting point for a multi-dimensional investigation regarding the need for rehabilitation has been introduced. According to this, the need for rehabilitation is a multidimensional, qualitative construct, that can not be directly observed and measured. The empirical investigation, which is based on this, limits the description of the need for rehabilitation to the various patterns of determinants, (description by a set of requirement factors and arranged factors) which result in different effects. Therefore different samples regarding the qualitative aspect do not mean the lesser or greater need for rehabilitation based on a continuum of measurement, but different qualitative forms which are visible in different effects.
