The application of 'dysexecutive syndrome' measures across cultures: Performance and checklist assessment in neurologically healthy and traumatically brain-injured Hong Kong Chinese volunteers

Abstract

Deficits in planning, self-regulation and attention are a relatively common consequence of traumatic brain injury (TBI). Such “dysexecutive” deficits tend to be most exposed in complex, real world situations. Consequently, clinicians often have to rely on interviews, questionnaires and observation in their assessments. While there is little doubt that dysexecutive symptoms occur across different cultures, the expression of those symptoms, the way in which they are experienced by others, and the propensity of friends/relatives to report negative features may vary considerably. The cross-cultural use of standardized checklists and measures that have predominantly been studied with English speaking, Western groups therefore requires empirical support. Here a group of 68 healthy Chinese speaking volunteers were asked to complete translations of 2 UK developed questionnaires (the Dysexecutive Questionnaire and Cognitive Failures Questionnaire) measures and to perform 2 “executive” tasks (The Six Elements Test and the Tower of Hanoi). Their self ratings and the ratings of close relatives were very close to those seen in the original UK standardization samples—as was their performance on the 2 tasks. Accordingly, the conditions for assessing their clinical sensitivity were met. Comparison between 30 Chinese patients with TBI and matched controls showed that both questionnaires and tests were sensitive to the deficits in this group. (JINS, 2002, 8, 771–780.)
