Abstract

The Dysexecutive Questionnaire (DEX) is a tool for measuring everyday problems experienced with the dysexecutive syndrome. This study investigated the psychometric properties of a revised version of the measure (DEX-R), a comprehensive tool, grounded in current theoretical conceptualisations of frontal lobe function and dysexecutive problems. The aim was to improve measurement of dysexecutive problems following acquired brain injury (ABI). Responses to the DEX-R were collected from 136 men and women who had experienced an ABI (the majority of whom had experienced a stroke or subarachnoid haemorrhage) and where possible, one of their carers or family members (n = 71), who acted as an informant. Rasch analysis techniques were employed to explore the psychometric properties of four newly developed, theoretically distinct subscales based on Stuss model of frontal lobe function and to evaluate the comparative validity and reliability of self and informant ratings of these four subscales. The newly developed subscales were well targeted to the range of dysexecutive problems reported by the current sample and each displayed a good level of internal validity. Both self- and independent-ratings were found to be performing reliably as ou...Continue Reading
