Validität und Reliabilität einer deutschen Version der Geriatrischen Depressionsskala (GDS)
Abstract
Zusammenfassung. In diesem Artikel berichten wir über die Validität und Reliabilität einer deutschen Version der “Geriatric Depression Scale (GDS)”. 43 Patienten im Alter zwischen 60 bis 87 Jahren wurden während ihres stationären Aufenthaltes auf einer psychiatrischen oder chirurgischen Station mit dem Mini-Mental-Status-Test, dem Diagnostischen Kurzinterview bei Psychischen Störungen (Mini-DIPS) und der GDS untersucht. Die GDS wies bei einem kritischen Wert von 13 Punkten die beste Sensitivität (84.0 %) und Spezifität (88.9 %) auf. Bei der 15-Item Kurzform der GDS konnte bei einem kritischen Wert von 6 die beste Sensitivität (84.0 %) und Spezifität (88.9 %) erzielt werden. Die mittlere Trennschärfe (.49), die mittlere Fragebogenschwierigkeit (P = 43), die niedrige Interitemkorrelation (r = .19) und die hohe innere Konsistenz (Cronbach alpha = .91) weisen die deutsche Version der GDS insgesamt als Fragebogen mit guten psychometrischen Eigenschaften aus.
Abstract. The psychometric properties of the German version of the Geriatric Depression Scale (GDS) were examined. Fourty-three patients with an age range from 60 to 87 were selected during their stay at a surgery or gerontopsychiatric unit. All patients were assessed with the Mini-Mental State Examination, a structured clinical interview (Mini-DIPS) and the GDS. Results suggest that a cutoff score of 13 revealed the best sensitivity (84.0 %) and specifity (88.9 %). For the 15-item short form a cutoff score of 6 yielded the best sensitivity (84.0 %) and specifity (88.9 %). Item analyses showed that the German version of the GDS is a questionnaire with average item discrimination (.49), average item difficulty (P = 43), low interitem correlation (r = .19) and a very high internal consistency (Cronbach alpha = .91). These results support the notion that the German version of the GDS is a reliable and valid screening instrument in discriminating patients with a depressive disorder.
