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 Antonucci Map. It was administered to subjects in
 Cohorts 3, 6, 9, and 12 and provided information regarding the
subject's close friendships.

 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.
 <strong>Longitudinal Cohort Study</strong>
 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.
 <strong>Antonucci Map</strong>
 The data in this collection are from Wave 3 of the Longitudinal
 Cohort Study, which was administered between 2000 and 2002. The data
 files contain information from the Antonucci Map protocol. The
 Antonucci Map instrument collected information regarding the subject's
close friendships.

 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.
 
 <strong>Longitudinal Cohort Study</strong>
 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 in the Wave 1 data
 collection, 5,338 were interviewed in the Wave 2 data collection, and
 4,850 were interviewed in the Wave 3 data collection.
 Data collection for Wave 3 began in 2000 and ended in 2002. It
 included a letter sent to study participants notifying them that they
 would be contacted to schedule an interview. Additional information on
 the contact log included the dates and research assistant ID of the
 Wave 2 interview (or the status of the case if incomplete in Wave 2),
 a list of household composition and ID numbers of other household
 members in the study, the name the telephone was listed under, the
 recontact information from Waves 1 and 2, and an updated history of
 addresses.
 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. An abbreviated
 telephone interview was conducted for the primary caregivers in
 Cohorts 0-15 and Cohort 18 study participants in Wave 3 who lived
 outside the nine-county metropolitan area to which research assistants
 were able to travel for interviews. In Wave 3, phone interviews were
 also conducted with the study participants in Cohort 15. People who
 refused to complete the two-hour in-person interview were administered
 the phone interview. A total of 391 telephone interviews were
 conducted during Wave 3, representing 6.3 percent of the sample.
 Proxy interviews were conducted with study participants who were
 emancipated minors (under 18 but married or living independently). The
 study participants answered questions from the primary caregiver's
 interview on the primary caregiver's behalf. In Wave 3, one primary
 caregiver and eleven study participants (young adults) were
 interviewed in jail. They were located in either the Cook County Jail
 or in one of the state prisons. Those study participants in a state
 system outside the nine-county area were also interviewed by
 phone. Study participants in foster care could not be interviewed. The
 Department of Children and Family Services did not allow interviews of
 the foster parent or the child. Permission was granted for a brief
 period in Wave 1, therefore there are some children in the sample who
 could not be followed up in Waves 2 and 3. Some children were not in
 foster care in Wave 1 but were placed in foster care by Wave 2 or
 3. They were also not followed up. Lastly, some participants were
 interviewed in Wave 3 but not in Wave 2, as they were in foster care
 during Wave 2.
 Some participants in Wave 1 spoke a language other than English,
 Spanish, or Polish. In Wave 3, an abbreviated version of the primary
 caregiver's protocol was administered, and the research assistant
 arranged for someone in the household to translate on the spot. In
 Wave 3, the complete protocol was translated into Spanish.
 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.
 For primary caregivers included in Wave 3 but not in Wave 2, an
 addendum interview was administered consisting of measures or portions
 of measures from the Wave 2 interview. An addendum was also given to
 the Cohort 15 and 18 study participants who were not included in Wave
 2. A total of 164 primary caregivers and 62 young adult (Cohorts 15
 and 18) addendums were completed in Wave 3.
 
 <strong>Antonucci Map</strong> 
 The Antonucci Map instrument was administered to subjects in
 Cohorts 3, 6, 9, and 12. It collected information regarding the
 subject's close friendships. Respondents were asked to list their
 close friends and then asked to consider if they would place each of
them in their inner or outer circle of friends.
description: The data files contain information relating to the
 subject's close friendships. Respondents were asked to name up to 10
 close friends and provide the gender, age, and relation to each
 friend. Respondents were also asked if each friend would be considered
part of their inner or outer circle of friends.
