Suicide is a leading cause of death for children and youth in the United States. Although school based programs have been the principal vehicle for youth suicide prevention efforts for over two decades, few have been systematically evaluated. This study examined the effectiveness of the Signs of Suicide (SOS) prevention program in reducing suicidal behavior.
4133 students in 9 high schools in Columbus, Georgia, western Massachusetts, and Hartford, Connecticut were randomly assigned to intervention and control groups during the 2001-02 and 2002-03 school years. Self-administered questionnaires were completed by students in both groups approximately 3 months after program implementation.
Significantly lower rates of suicide attempts and greater knowledge and more adaptive attitudes about depression and suicide were observed among students in the intervention group. Students' race/ethnicity, grade, and gender did not alter the impact of the intervention on any of the outcomes assessed in this analysis.
This study has confirmed preliminary analysis of Year 1 data with a larger and more racially and socio-economically diverse sample. SOS continues to be the only universal school-based suicide prevention program to demonstrate significant effects of self-reported suicide attempts in a study utilizing a randomized experimental design. Moreover, the beneficial effects of SOS were observed among high school-aged youth from diverse racial/ethnic backgrounds, highlighting the program's utility as a universal prevention program.

在美国，自杀是儿童和青少年的主要死因。尽管二十多年来，以学校为基础的项目一直是预防青少年自杀工作的主要手段，但很少有项目得到系统评估。本研究考察了自杀迹象（SOS）预防项目在减少自杀行为方面的有效性。
在2001 - 02学年和2002 - 03学年，佐治亚州哥伦布市、马萨诸塞州西部和康涅狄格州哈特福德市9所高中的4133名学生被随机分配到干预组和对照组。两组学生在项目实施约3个月后完成自我管理问卷。
干预组学生的自杀未遂率显著降低，对抑郁症和自杀有更多的认识和更适应性的态度。学生的种族/民族、年级和性别并未改变干预对本分析中评估的任何结果的影响。
本研究用一个更大、种族和社会经济背景更多样化的样本证实了对第一年数据的初步分析。在一项采用随机实验设计的研究中，SOS仍然是唯一显示出自杀未遂有显著效果的全校性自杀预防项目。此外，在不同种族/民族背景的高中年龄段青少年中都观察到了SOS的有益效果，突出了该项目作为一种普遍预防项目的效用。
