title: [Which schizophrenic patients improve under work therapy, which ones don't?].
abstract: This investigation is part of a multicenter study, where only small effects and no superiority compared to creative ergotherapy was found for four weeks of inpatient work therapy. The criteria were three scales of the Osnabrück-Working Capabilities Profile (O-AFP) assessing basic learning ability, social communication ability and adaptation at the work place. The goal of this investigation is to identify subgroups of patients within the work therapy group, which differ in their course of ability level during the intervention. Three subgroups were identified for each scale. Subgroups with improvements comprise 24 % (learning ability) and 15 % (social communication) of the sample. Adaptation level decreases in a group of 9 % of the patients. The remaining clusters show constancy of abilities at different levels. Comparison of the clusters with neurocognitive, symptom and motivational variables shows that for learning ability mainly neurocognitive variables yield salient differences, whereas for social communication abilities, symptoms and motivation, together with a specific aspect of memory, seem to be characteristic. Only positive symptoms are related to adaptation. Also, there are hints for variables that specifically characterize patients with improvement of ability level. The discussion deals with issues of assessment and prognosis in rehabilitation, contributions to the neurocognitive theory of schizophrenia and to the development of person-centered interventions.
