Diskrete subjektive effekte kognitiver vulnerabilität bei gesunden und schizophrenen ein empirischer beitrag zum basisstörungskonzept

The goal of this study was the testing of some hypotheses which result from the theoretical relation between the concepts of basic disorders and vulnerability; especially, a trait component of basic symptoms was searched. 57 healthy adults where investigated with a new questionnaire for measurement of basic symptoms (Basic Inventory Eppendorf, BInE); furthermore, the Continuous Performance Test (CPT), the Span of Apprehension Task, and a Modality Shift paradigm were conducted. BInE total score and CPT were significantly correlated (r _xy = -.30). This correlation was due mainly to 23 Items (subscale "subjective effects of cognitive vulnerability", DEV) describing cognitive every-day failures, which were interpreted as trait basic symptoms. The DEV scale was further examined with 40 schizophrenic inpatients. As expected, schizophrenics reached a higher DEV mean score than the healthy group; the DEV scale again was correlated negatively with the CPT; the DEV scale correlated with positive syndrome. However, the CPT failed to show significant group differences.
