Project on Human Development in Chicago Neighborhoods (PHDCN): Post-Traumatic Stress Disorder, Past Year (Subject), Wave 3, 2000-2002

The Project on Human Development in Chicago Neighborhoods (PHDCN) was a large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. One such measure was the subject version of the Post-Traumatic Stress Disorder (Past Year Section), administered to subjects for Cohorts 6, 9, 12, 15, and 18. The instrument was adapted from the Anxiety module of the Diagnostic Interview Schedule for Children (DISC 4) and obtained information regarding any anxiety or stress the subjects may have experienced in the past year in relation to traumatic events that may have happened to them. It is closely related to PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): POST-TRAUMATIC STRESS DISORDER, PAST YEAR (SUBJECT), WAVE 2, 1997-2000 (ICPSR 13649). Subjects in Cohort 18 were administered a different version of the instrument than was administered to subjects in Cohorts 6, 9, 12, and 15.

芝加哥邻里人类发展项目（Project on Human Development in Chicago Neighborhoods, PHDCN）是一项大规模跨学科研究，旨在探究家庭、学校与邻里环境如何影响儿童及青少年的发展轨迹。该项目的子研究之一为纵向队列研究（Longitudinal Cohort Study），该项研究由一系列协同开展的纵向追踪研究构成，历时追踪了6000余名随机选取的儿童、青少年、青年群体及其主要照料者，以考察其生活环境的动态变化，以及可能促使其趋近或远离各类反社会行为的个人特征。研究人员向受访者施测了多种测评工具，以评估人类发展的多个维度，包括个体差异、家庭、同伴及学校环境的影响。其中一款测评工具为创伤后应激障碍（Post-Traumatic Stress Disorder）过去一年版受试者量表，已向第6、9、12、15及18队列的受试者施测。该量表改编自儿童诊断访谈量表（Diagnostic Interview Schedule for Children, DISC 4）的焦虑模块，用于收集受试者过去一年内因经历创伤性事件而产生的各类焦虑或应激体验。该数据集与《芝加哥邻里人类发展项目：创伤后应激障碍（过去一年，受试者版），第二波，1997-2000年（ICPSR 13649）》高度相关。第18队列的受试者所使用的量表版本，与第6、9、12及15队列的受试者所使用的版本存在差异。
