dc.description.abstractThe Dysexecutive Questionnaire is a sensitive and ecologically valid measure of everyday dysexecutive symptoms. Recently, a revised version of the tool has been proposed (DEX-R). The current study aimed to examine the factorial validity of the Greek DEX-R, the level of agreement between the self and informant rating versions and the effect of age on each dysexecutive symptoms component. The questionnaire was administered to a sample of older adults (n = 235) and to a sample of informants (n = 187) in the context of the Neurocognitive Study for the Aging in Cyprus. Confirmatory Factor Analysis results showed that dysexecutive symptoms can be grouped into three underlying components or factors: (a) Motivation and Attention, (b) Flexibility, Fluency and Working Memory, and (c) Social Self-Regulation. Overall, the elderly reported more symptoms than their relatives, however the difference was significant only for the Flexibility, Fluency and Working memory factor. In a structural equation model, a weak positive effect of age was observed on the Flexibility, Fluency and Working Memory factor, based on the informant ratings. This study provides empirical evidence about the use of the DEX-R questionnaire in the Greek-speaking elderly population as a valid and reliable measure of everyday dysexecutive symptoms.en
