Abstract
Ergebnisse zur Validierung der neuen Wechsler Memory Scale-IV (Deutsche Version) werden anhand von drei klinischen Stichproben (Depression, Hirnschädigung, Demenz; N = 165) vorgestellt. Für alle drei Gruppen zeigen sich signifikante Unterschiede mit hohen Effektstärken zu den parallelisierten gesunden Kontrollgruppen. Während die Patienten mit Demenz global sehr niedrige Ergebnisse zeigten, sind die Leistungen der Patienten mit Depression im unteren Durchschnittsbereich und die der Patienten mit Hirnschädigung weichen um 1,5 bis 2 Standardabweichungen nach unten ab. Damit zeigen sich erste Befunde, dass die WMS-IV nicht nur zwischen klinischen und nicht klinischen Gruppen trennen kann, sondern auch störungsbezogene Abstufungen von Gedächtnisbeeinträchtigungen darstellen kann.
Evidence of validity for the new German edition of the Wechsler memory Scale-IV was investigated in three clinical samples (depression, brain injury, dementia; N = 165). Significant differences of mean performances of each clinical sample and matched healthy controls can be observed together with large effect sizes. While patients with dementia show very low overall memory performances, patients with depression perform in the lower normal range and patients with brain damages reveal performances 1.5 to 2 standard deviations lower than controls. These initial results indicate the sensitivity of the Wechsler Memory Scale – IV to different clinical disorders.
