Dutch translation and adaptation of the Barkley Deficits in Executive Functioning Scale (BDEFS)

Keywords: Self-regulation, executive functions, assessment, reliability, validity

Abstract

Background: Based on his model of self-regulation and executive functions, Barkley developed a self- and other-report questionnaire (the Barkley Deficits in Executive Functioning Scale – BDEFS). The BDEFS measures deficits in executive functions as expressed in daily life activities like self-management of time, self-organization, self-restraint, self-motivation, and self-regulation of emotion. Objectives: This study created and analyzed a Dutch translation and adaptation in conformance with official guidelines. Methods: The Dutch and English BDEFS were completed by 25 bilingual Dutch adults to evaluate semantic correspondence. Consequently, 60 Dutch participants completed the Dutch BDEFS, Barratt Impulsiveness Scale-Eleventh edition (BIS-11) and the Dysexecutive Questionnaire (DEX) to evaluate concurrent validity and internal consistency. Results: The versions demonstrated sufficient semantic equivalence and Spearman’s rho of total scores was high; items mostly showed moderate-to-high correlations. Regression analysis showed no proportional bias. Internal consistency was also high. Correlations between BDEFS, BIS-11 and DEX supported concurrent validity. Discussion: We conclude that a successful BDEFS translation and adaptation was created with satisfactory reliability and validity. Further research should assess the utility of the BDEFS in Dutch clinical practice.
