Scoring
The Wender Utah Rating Scale (WURS) scores the same set of 25 questions in both the abbreviated version (WURS-25) and the extended version (WURS-61), which includes an additional 36 unscored questions. Respondents rate each question on a five-point Likert scale ranging from 0 points ("not at all or very slightly") to 4 points ("very much"). The cumulative score spans from 0 to 100. A cutoff score of 36 or higher was able to accurately identify 96% of adults with ADHD and 96% of adults without ADHD. When the cutoff score was raised to 46 or higher, the assessment was able to accurately identify 86% of adults with ADHD and 99% of adults without ADHD.
