Error in Results

In the Original Investigation titled “The World Health Organization Adult Attention-Deficit/Hyperactivity Disorder Self-report Screening Scale for DSM-5,”¹ published online April 5, 2017, and in the May 2017 print issue, there was an error in the Results section of the article. In the second paragraph of “Choosing the Optimal Number of Screening Questions,” option 3 included the phrase “Criterion A2e, acts as if ‘driven by a motor.’” The phrase should have been “Criterion A2d, difficulty playing quietly/leisure time.” This article was corrected online.
