Objective Adult attention‐deficit/hyperactivity disorder (ADHD) is a prevalent disorder with serious impairments, but it often remains undetected. The aim of the study was to develop an ADHD screening scale from the Symptom Check‐List‐90‐R (SCL‐90‐R) and describe its psychometric properties. The item selection was based on the ADHD‐specific Conners' Adult ADHD Rating Scale (CAARS‐S:L). Method In total, 412 subjects of an ADHD Special Consultations Unit were investigated, who completed the SCL‐90‐R, CAARS‐S:L, and ADHD Self‐Rating Behavior Questionnaire. Results The ADHD‐SCL‐90‐R Screening Scale consisted of 16 items with a four‐factor structure, including Inattention/Memory Problems, Hyperactivity/Restlessness, Impulsivity/Emotional Lability, and Problems with Self‐Concept. It showed excellent internal consistency (Cronbachs α = .90) and good convergent validity ( r = .57–.59). Sensitivity was 78%, specificity was 56%, and the discriminatory power was acceptable (area under the curve = 0.74). Conclusion The newly developed ADHD‐SCL‐90‐R Screening Scale showed good psychometric properties, and it has a versatile application in clinical practice.
