Selbst- und Fremdwahrnehmung von Beeinträchtigungen exekutiver Funktionen bei Erwachsenen mit ADHS

Published Online:https://doi.org/10.1024/1661-4747/a000108

Zusammenfassung.Es wurde untersucht, ob bei der Diagnostik exekutiver Störungen bei Erwachsenen mit Aufmerksamkeits-Defizit/Hyperaktivitätsstörung (ADHS) Diskrepanzen zwischen Selbst- und Fremdangaben sowie zwischen Fragebögen und Testergebnissen auftreten. Erwachsene mit ADHS und Kontrollprobanden füllten das Dysexecutive Questionnaire (DEX) und die Frankfurter Selbstkonzeptskalen (FSKN) aus und bearbeiteten exekutive Testverfahren. Es zeigte sich, dass Erwachsene mit ADHS sowohl in Selbst- als auch Fremdurteil im DEX auffälliger waren als Kontrollprobanden. Selbst- und Fremdurteile stimmten in beiden Gruppen etwa gleich gut überein. Bei Patienten und bei Kontrollen erbrachte die Selbsteinschätzung auffälligere Werte als die Fremdeinschätzung durch Angehörige. Zusammenhänge zwischen DEX-Einschätzungen und Testleistungen waren gering bis höchstens moderat. Die Ergebnisse zeigen, dass Selbstangaben von Erwachsenen mit ADHS zu exekutiven Funktionsbeeinträchtigungen als überwiegend zuverlässig angesehen werden können.


Self-Perception and Perception of Executive Function Impairments in Adults with ADHD

Abstract.In the present study we examine whether adults with ADHD make accurate self-judgments of executive function deficits, compared to significant others’ ratings and to objective test performance. Adults with ADHD and controls completed the Dysexecutive Questionnaire (DEX) as well as a standardized self-rating instrument on self-concept (Frankfurt Self-Concept Scales, FSKN) and performed executive tests. Adults with ADHD were more impaired than controls according to both self- and informant ratings. The agreement between self- and informant ratings was equally good in both groups. For both groups, self-ratings revealed higher impairment scores than ratings by significant others. The correlations between test performances and DEX-ratings were low to moderate. These results indicate that self-ratings of adults with ADHD regarding executive deficits may be considered as predominantly reliable.
