title: Project on Human Development in Chicago Neighborhoods (PHDCN): Exposure to Violence (Subject), Wave 1, 1994-1997
title: Version 1

description: 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 Exposure to Violence (ETV), administered to those subjects belonging to Cohorts 9 to 18. It assessed the subject's experience of exposure to different types of violent acts, as well as how exposure to violence may have affected the subject, his or her family, and friends.
description: Project on Human Development in Chicago Neighborhoods 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. It was designed to advance the understanding of the developmental pathways of both positive and negative human social behaviors. In particular, the project examined the causes and pathways of juvenile delinquency, adult crime, substance abuse, and violence. At the same time, the project provided a detailed look at the environments in which these social behaviors took place by collecting substantial amounts of data about urban Chicago, including its people, institutions, and resources. Longitudinal Cohort Study 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. The age cohorts include birth (0), 3, 6, 9, 12, 15, and 18 years. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. Exposure to Violence (Subject) The data files contain information from the Exposure to Violence (ETV) protocol (Subject version). The PHDCN version of the ETV was adapted from the most widely used measure of exposure to violence, the Survey of Children's Exposure to Community Violence, which was designed to assess the frequency with which a child victimized by, witnessed, or heard about 20 different forms of violence and violence related activities in the community. The Subject version of the ETV instrument used in the PHDCN Longitudinal Cohort study was designed to assess the subject's experience of exposure to four different types of violent acts. These include: seeing someone shoved, kicked, or punched, seeing someone attacked with a knife, hearing a gunshot, and seeing someone shot. The purpose of the ETV protocol was to advance current understanding of the frequency, form, and consequences of child and adolescent exposure to violence.
description: Project on Human Development in Chicago Neighborhoods The city of Chicago was selected as the research site for the PHDCN because of its extensive racial, ethnic, and social-class diversity. The project collapsed 847 census tracts in the city of Chicago into 343 neighborhood clusters (NCs) based upon seven groupings of racial/ethnic composition and three levels of socioeconomic status. The NCs were designed to be ecologically meaningful. They were composed of geographically contiguous census tracts, and geographic boundaries and knowledge of Chicago's neighborhoods were considered in the definition of the NCs. Each NC was comprised of approximately 8,000 people. Longitudinal Cohort Study For the Longitudinal Cohort Study, a stratified probability sample of 80 neighborhoods was selected. The 80 NCs were sampled from the 21 strata (seven racial/ethnic groups by three socioeconomic levels) with the goal of representing the 21 cells as equally as possible to eliminate the confounding between racial/ethnic mix and socioeconomic status. Once the 80 NCs were chosen, then block groups were selected at random within each of the sample neighborhoods. A complete listing of dwelling units was collected for all sampled block groups. Pregnant women, children, and young adults in seven age cohorts (birth, 3, 6, 9, 12, 15, and 18 years) were identified through in-person screening of approximately 40,000 dwelling units within the 80 NCs. The screening response rate was 80 percent. Children within six months of the birthday that qualified them for the sample were selected for inclusion in the Longitudinal Cohort Study. A total of 8,347 participants were identified through the screening. Of the eligible study participants, 6,228 were interviewed. For all cohorts except 0 and 18, primary caregivers as well as the child were interviewed. The primary caregiver was the person found to spend the most time taking care of the child. Separate research assistants administered the primary caregiver interviews and the child interviews. The primary method of data collection was face-to-face interviewing, although participants who refused to complete the personal interview were administered a phone interview. Interviews were conducted in Spanish, English, and Polish. In Wave 1 the complete protocol was translated into Spanish and Polish. An interpreter was hired for participants who spoke a language other than English, Spanish, or Polish. Depending on the age and wave of data collection, participants were paid between $5 and $20 per interview. Other incentives, such as free passes to museums, the aquarium, and monthly drawing prizes were also included. Interview protocols included a wide range of questions. For example, some questions assessed impulse control and sensation-seeking traits, cognitive and language development, leisure activities, delinquency and substance abuse, friends' activities, and self-perception, attitudes, and values. Caregivers were also interviewed about family structure, parent characteristics, parent-child relationships, parent discipline styles, family mental health, and family history of criminal behavior and drug use. Exposure to Violence (Subject) Completed between 1994 and 1997, the Exposure to Violence (ETV) instrument was completed by subjects belonging to Cohorts 9 to 18 of the PHDCN Longitudinal Cohort Study. The Subject version of the ETV instrument was designed to assess the subject's experience of exposure to four different types of violent acts. These include: seeing someone shoved, kicked, or punched, seeing someone attacked with a knife, hearing a gunshot, and seeing someone shot. This measure also assessed the location and frequency of such events, as well as the identification of victim(s) and/or perpetrator(s), and the subject's relationship to both (e.g., parent, friend, sibling, etc.).

description: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection: Performed recodes and/or calculated derived variables.; Checked for undocumented or out-of-range codes..

description: Response Rates: The overall response rate for Wave 1 of the Longitudinal Cohort Study was 75 percent or 6,228 participants. The response rates by cohort were: 76.2 percent (1,269) for Cohort 0; 76.6 percent (1,003) for Cohort 3; 75.0 percent (980) for Cohort 6; 75.9 percent (828) for Cohort 9; 74.3 percent (820) for Cohort 12; 71.6 percent (696) for Cohort 15; 70.3 percent (632) for Cohort 18;
