Abstract
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.

Summary
Executive function is currently seen as being compromised in several mental disorders (for example[1,2,3,4,5,6,7,8,9,10]). Barkley divides the model of self-regulation into two levels: an automatic level and an executive level that monitors and injects several (executive) actions into the automatic level. As self-regulatory executive function is compromised in several mental disorders, its assessment is relevant for diagnostics and tailor made treatment indications. 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). 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. Further research should assess the utility of the BDEFS in Dutch clinical practice
