It is important for an individual’s everyday functioning and skill set. Thus, over the years executive functioning has become a prominent construct among researchers, practitioners and in literature. This popularity has resulted in challenges establishing comparable estimates of psychometric properties. Executive functioning is typically measured by performance-based measures however, recently there is emerging support for the use of self-report measures. In developing countries such as South Africa, research on executive functioning will receive a substantial injection if self-reports were found to be reliable and valid alternatives to costly and inaccessible performance-based measures. The Amsterdam Executive Function Inventory (AEFI), a measure of executive functioning, has been used recently in South Africa with good reliability and internal stability reported as evidenced by acceptable Cronbach alphas.enExecutive functioningAmsterdam executive functioning inventorySelf-report measurePsychometric studyValidation studyUniversity of the Western Cape
