Abstract The Wender-Reimherr adult attention deficit disorder scale (WRAADDS; Wender, 1995) is a clinician-rated scale based on the Utah Criteria for attention-deficit/hyperactivity disorder (ADHD) in adults. It assesses ADHD symptom severity across 7 domains: attention difficulties, hyperactivity/restlessness, temper, affective lability, emotional over-reactivity, disorganization, and impulsivity. The normative sample consisted of 120 males and females ages 20-49 with no personal or family history of ADHD. Patients with ADHD met Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000) criteria, included males and females ages 20-60, and came from 5 clinical trials. Measures of reliability (test-retest r = .96; interrater r = .75) and internal consistency (Cronbach's alpha = 0.78) were acceptable. The WRAADDS correlated with the Conners' Adult ADHD Rating Scale (CAARS; Conners, Erhardt, & Sparrow, 1999) total scores (r = .501, p < .001). WRAADDS hyperactivity + impulsivity correlated with the CAARS hyperactivity/impulsivity (r = .601, p < .001), and WRAADDS attention + disorganization correlated with the CAARS inattention (r = .430, p < .001). Discriminate validity (adults with vs. without ADHD) was significant for all domains (p < .001). Factor analysis yielded a 2-factor solution accounting for 58\% of the variance, one containing the emotional dimensions and the second containing attention and disorganization. Hyperactivity/restlessness and impulsivity were split between both factors. Changes in response to treatment for the WRAADDS and CAARS were highly correlated (p < .001). These psychometric data support continued use of the WRAADDS in adults with ADHD. This article was published in Psychol Assess and referenced in Journal of AIDS & Clinical Research
