Executive Functions Test-Elementary: Normative Update (EFT-E:NU)
The EFT-E:NU measures language skills that affect executive functions, such as working memory, problem solving, inferring, predicting outcomes, and shifting tasks. It can be used to identify children who have executive-functioning deficits, plan interventions, and represent executive functioning in research studies. The average coefficient alpha ranges from 0.77 to 0.91 for the subtests and is 0.95 for the composite. New validity studies demonstrate the test's ability to differentiate students with autism and learning disabilities from typically developing students. The norms have been updated to reflect the demographics of the 2015 U.S. Census.
- The normative sample (N = 647) is stratified by age relative to geographic region, gender, race, and ethnicity
- A new standard score metric has been implemented for subtests and composites (M = 10, SD = 3; M = 100, SD = 15)
- New item-analysis and item-bias studies provide convincing evidence of content-description validity
- New reliability and validity studies were prepared, including diagnostic accuracy analyses, which are considered the most rigorous techniques for establishing a test's validity. These analyses involve the computation of sensitivity and specificity indexes and the receiver operating characteristic/area under the curve (ROC/AUC) statistic.
Administration and Scoring
The test has four subtests (Attention and Immediate Memory-Verbal, Attention and Immediate Memory-Verbal and Nonverbal, Working Memory and Flexible Thinking, and Shifting) that yield scaled scores. A composite score, called the Executive Function Index, represents overall performance on the subtests.
