The Amsterdam Executive Function Inventory (AEFI): psychometric properties and demographically corrected normative data for adolescents aged between 15 and 18 years.

The Amsterdam Executive Function Inventory (AEFI) is a newly developed brief self-report questionnaire to assess three important components of the executive aspects of daily-life behavior--that is, Attention, Self-Control and Self-Monitoring, and Planning and Initiative. In a population-based study, the AEFI was administered to N = 6,730 Dutch adolescents aged between 15 and 18 years. Psychometric analyses showed that the construct validity and the reliability of the AEFI were adequate. Educational level and gender affected the different AEFI scale scores. Regression-based normative data that took these demographic influences into account were established, so that the AEFI can be used by clinicians and researchers who need to assess executive aspects of daily-life behavior.
