Differentielle validitat des fragebogen erlebter defizite der aufmerksamkeit (FEDA): Konkurrente validierungsergebnisse bei schizophrenen und depressiven patienten

The FEDA is as a self-assessment instrument which taps subjective attention impairments in everyday life in brain-damaged patients. In this study the FEDA was administered to 40 psychiatric patients (20 paranoid schizophrenics and 20 depressives) and 20 control subjects along with several objective attention measures. In the case of schizophrenic patients, evidence of concurrent validity was obtained: the subscales 'distractibility and slowing down of cognitive processes' and 'fatigue and slowing down of practical activities' were correlated with error rates of attention endurance tests and with processing time in the Trail-Making-Test B which requires divided attention. No evidence of validity was found for depressive patients. Thus, the FEDA seems to possess a differential validity with regard to psychiatric patients.
