Dysexecutive Questionnaire

The Dysexecutive Questionnaire (DEX) is a measure of executive function and is used in the assessment of dysexecutive syndrome.

It is a 20-item questionnaire designed to sample emotional, motivational, behavioural and cognitive changes in a subject with DES. One version is designed for the subject to complete and another version is designed for someone who is close to the individual, such as a relative or caregiver. Instructions are given to the participant to read 20 statements describing common problems of everyday life and to rate them according to their personal experience. Each item is scored on a 5-point scale according to its frequency from ‘‘never’’ (0 point) to ‘‘very often’’ (4 points).
