In the Original Investigation titled “Stepped Collaborative Care Targeting Posttraumatic Stress Disorder Symptoms and Comorbidity for US Trauma Care Systems: A Randomized Clinical Trial,” 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.

摘要和方法错误

在 2021 年 5 月号发表的题为“针对美国创伤护理系统的创伤后应激障碍症状和合并症的阶梯式协作护理：一项随机临床试验”的原始调查中，摘要和方法中存在重复错误。在每个地方，作为“2018 年 11 月”的研究结束日期应该是“2019 年 11 月”。本文已被纠正。本文还在 2021 年 3 月 31 日更正，以修正作者单位的拼写。
