Error in Abstract and Methods

In the Original Investigation titled “Stepped Collaborative Care Targeting Posttraumatic Stress Disorder Symptoms and Comorbidity for US Trauma Care Systems: A Randomized Clinical Trial,”¹ published in the May 2021 issue, there was a repeated error in the Abstract and the Methods. In each place, the study end date given as “November 2018” should have been “November 2019.” This article has been corrected. This article was also corrected on March 31, 2021, to fix the spelling of an author affiliation.
