This study explores whether a school-based group counseling program for adolescent girls, implemented at scale, can mitigate trauma-related mental health harms. In a randomized trial involving 3749 Chicago public high school girls, we find that participating in the program for 4 months induces a 22% reduction in posttraumatic stress disorder symptoms and find significant decreases in anxiety and depression. Results surpass widely accepted cost-effectiveness thresholds, with estimated cost-utility well below $150,000 per quality adjusted life year. We find suggestive evidence that effects persist and may even increase over time. Our results provide the first efficacy trial of such a program specifically designed for girls, conducted in America's third largest city. These findings suggest the promise of school-based programs to mitigate trauma-related harms.
本研究探讨了在大规模实施的情况下，针对青春期少女的学校团体心理咨询方案是否可以减轻与创伤相关的心理健康伤害。在一项涉及 3749 名芝加哥公立高中女生的随机试验中，我们发现，参加该方案 4 个月可使创伤后应激障碍症状减少 22%，并显著降低焦虑和抑郁症状。结果超过了广泛接受的成本效益阈值，估计每获得一个质量调整生命年的成本效益低于 15 万美元。我们有迹象表明，效果可能会持续存在，甚至随着时间的推移而增加。我们的研究结果提供了首个专门为女孩设计的此类方案的疗效试验，该试验在美国第三大城市进行。这些发现表明，学校方案有潜力减轻与创伤相关的伤害。
