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. Once such measure was the subject self-report version of the Exposure to Violence. For Wave 2, a much more detailed version of the instrument than was used in Wave 1 was developed to assess exposure to violence. It was called, My Exposure to Violence (Subject), or ETVS. This detailed subject self-report instrument was administered to Cohorts 9 to 15 and obtained information regarding the subject's lifetime and past year exposure to violent events. In addition, a short form of the subject self-report instrument was used with subjects in Cohort 6. The subject self-report instrument is complemented by the parent-report instrument PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): MY CHILD'S EXPOSURE TO VIOLENCE, WAVE 2, 1997-2000 (ICPSR 13619).
