Zusammenfassung

In der vorliegenden Arbeit wurde die von den Autoren des Instrumentes postulierte dreifaktorielle Struktur der deutschen Version der 20-Item-Toronto-Alexithymie-Skala an einer Stichprobe von 419 psychogen erkrankten Patienten mittels konfirmatorischer Faktorenanalyse überprüft. Es ergab sich jedoch weder eine befriedigende interne Konsistenz aller Subskalen, noch resultierte eine akzeptable Anpassung der erhobenen Daten an das dreifaktorielle Modell. Mittels explorativer Hauptkomponentenanalyse war daraufhin der Versuch unternommen worden, ein konsistenteres Alternativmodell zu ermitteln. Die resultierende vierfaktorielle Struktur ist inhaltlich gut interpretierbar und konsistent sowohl im Hinblick auf Theorie als auch auf empirische Befunde zum Alexithymiekonstrukt. Zur weiteren Absicherung der Stabilität der resultierenden Struktur ist noch eine Kreuzvalidierung an einer zweiten Stichprobe notwendig.

Factorial Structure and Psychometric Properties of the German Version of the Toronto Alexithymia Scale (TAS-20) of Psychosomatic Patients

The present paper describes the attempt to cross-validate the three-factorial structure of the German Version of the 20-Item Toronto Alexithymia Scale in a population of 419 patients, suffering of psychogenic disorders. However, results neither revealed good internal consistencies nor was it possible to obtain an acceptable adaptation of the empirical data on the postulated model. Therefore an explorative factor analysis was performed in order to get a more consistent factor model. The hereby resulting four-factorial structure was congruent with reference to theoretical and empirical data of alexithmyia. However, additional crossvalidation in other populations has to be investigated.
