Adult ADHD Self Report Scale (18-Question ASRS)

The following is the ADHD Self-Report Scale adapted without alteration from the ASRS posted by the World Health Organization's comorbidity study at Harvard. The Adult ADHD Self-Report Scale (ASRS) is an 18-item self-report screening tool for attention-deficit hyperactivity disorder in adults. It was developed in conjunction with a revision of the WHO Composite International Diagnostic Interview (CIDI). The The first six questions assess DSM-IV Criterion A symptoms of Attention-Deficit Hyperactivity Disorder, and perform well in sensitivity analyses (65% - 70%) and in specificity analyses (99.5%). The ASRS has been well-validated for a number of different adult populations, and remains one of the most popular measures for assessing ADHD in adults worldwide. Each question asks how often a symptom has occurred over the past 6 months on a 0–4 scale, with responses of never (0), rarely (1), sometimes (2), often (3), and very often (4). The items identify the common symptoms of ADHD. It takes between 1 and 5 minutes to complete. This scale is intended for research or educational purposes. Data from the study's clinical validation sub-sample of the NCSR dataset were used to generate cutoff scores. The test takes between 3-5 minutes to complete. Please answer the questions below, rating yourself on each of the criteria shown using the scale below. As you answer each question, check the button that best describes how you have felt and conducted yourself over the past 6 months.
