Unit of Observation:
Family intervention group
All children attending kindergarten during the recruitment period, which began in Fall of 2006, at six participating schools in Chicago, Illinois, their families, and their teachers. Seventh and eighth graders recommended by teachers at the six participating schools. Family intervention providers at two community agencies providing mental health services in the neighborhoods in which the schools were located.
Data Collection Notes:
This study consisted of two distinct components. The first was an effectiveness evaluation comparing a control group of children and parents to a treatment group that participated in the SAFEChildren program. The second was a process and fidelity measurement which looked only at the experiences of the treatment group. The Sample Data and Twin ID Data (Datasets 1 and 2) provide data on participants, and link the two components of the study. Datasets 3-13 include data exclusively associated with the process and fidelity measurement. Datasets 14-25 include data exclusively associated with the effectiveness evaluation.
Users should be aware that there is a slight case count discrepancy between the final report for this study (Henry, Tolan, Schoeny, Zwaniger, and Kim, 2012; NCJRS 238972) and the data provided to ICPSR. The final report references 384 children participating, including 191 students/families randomized to the treatment condition. However, one family withdrew consent after the intervention (consistent with the procedure detailed in the consent form), and their data were removed from the database, leaving data on a total of 383 children, including 190 in the treatment condition. Additionally, the report indicates that there were five participating schools. However because the specific schools involved changed between the two cohorts, the Therapist Fidelity Data (Datasets 5, 7, and 9) include a variable with values for 6 schools. At any given time no more than five separate schools participated.
The final report for this study (Henry, Tolan, Schoeny, Zwaniger, and Kim, 2012; NCJRS 238972) includes a Cost-Benefit analysis. The data used in that analysis are from the SAFE Follow-up Study (discussed in detail on pages 36-46 of the final report), and are not available as part of this collection.
The purpose of the study as described by the principal investigators includes exploring network processes, and the final report for the study (Henry, Tolan, Schoeny, Zwaniger, and Kim, 2012; NCJRS 238972) includes a social network process assessment. Data pertaining to network processes are not included in this collection.
The final report for this study (Henry, Tolan, Schoeny, Zwaniger, and Kim, 2012; NCJRS 238972) refers to questionnaires completed by family providers from the community mental health centers on demographic information and their experience in conducting preventive interventions similar to the intervention implemented in SAFEChildren. Data from these questionnaires are not available as part of this collection.
The purpose of this study was to evaluate the effectiveness of SAFEChildren when implemented with community providers of the family intervention and tutors recruited from the student bodies of the participating schools (the SAFE Effectiveness Trial). Specifically, the first goal was to test the effects of the SAFE Effectiveness Trial intervention. The second goal was to explore network processes within the groups and their relations to outcomes. The third was to explore pre-existing provider attitudes and process and fidelity measures, and their relations to outcome.
The SAFE Effectiveness Trial (SAFE-E) involved community providers delivering the family group intervention portion of the SAFEChildren intervention and upper grade students delivering the tutoring program. The primary target sample for this study was the children (and their parents/caregivers) enrolled in first grade at six elementary schools in disadvantaged neighborhoods in Chicago, Illinois. In addition, teachers were enrolled to provide sources of data about the children; tutors and mental health service providers were also included as participants in the study. Individual children and their families were randomly assigned to treatment or control conditions. In addition to the 1st grade participants, 278 7th and 8th graders who had been nominated by teachers were recruited to be trained and to participate as tutors for the 1st grade children in the treatment condition. Because of the principal investigators' prior involvement with Chicago area inner-city, several schools were interested in participating prior to the beginning of the project. The two community mental health agencies that were recruited were agencies that served the communities in which the schools were located.
A two-stage procedure was used for recruitment and consent of families. The participating schools provided the researchers with the names, addresses, and phone numbers of all children attending kindergarten. Initial information was sent to all families. Following these letters, program staff contacted each family by phone or home visit. The research program was explained to families and informed consent was obtained. Eighth-grade tutors were nominated by their teachers. A consent procedure similar to that of the first-grade participants was followed to secure parent consent and child assent for participation. The tutors received 40 hours of training prior to beginning the intervention and received 30 minutes of supervision each week during the course of the intervention. Providers were recruited and hired by their respective agencies, and trained by university personnel.
The study consisted of two components, a process and fidelity measurement looking at the parents, therapists and tutors who participated in the SAFEChildren program (Datasets 3-13), and an effectiveness evaluation that compared a control group of children and parents to a treatment group participating in the SAFEChildren program. Demographic and administrative data were collected for both the control and treatment groups (Dataset 1) as well as data about any twins participating in the study (Dataset 2). All interviews were conducted using laptop computers and were checked for accuracy and completeness.
The Process and Fidelity Characteristics portion of the study (Datasets 3-13) used a sample which consisted of the participants who were (1) randomly assigned to receive intervention, and (2) in attendance at the specific sessions wherein the measures were administered. Dataset 3 provides data on attendance at each session. This included the parents or caregivers of children in the treatment group (Datasets 3, 6, 8, and 11), the therapists (Datasets 5, 7, 9, and 12), and youth tutors (Datasets 10 and 13) participating in the study. Process assessments were completed at four week intervals during the interventions. Data were collected from families and group leaders for three constructs: Fidelity of Provision of Services (e.g., group activities); Group Intervention Processes (e.g., attitudes about the group leader, family involvement); and Provider Characteristics, (e.g., education, attitudes about prevention). At four sessions, tutoring supervisors completed ratings of the tutors and process measures were administered to the tutors. Tutoring supervisors rated tutors on "Quality of Relationship and Quality of Tutoring". The process measures completed by tutors comprised scales for "Tutees Relationship with the Tutor" and "About the Program".
For the effectiveness evaluation, family interviews were scheduled around convenient times for the family. The interviewer completed the child interview (Datasets 14, 17, 20, and 23) prior to interviewing the caregiver(s) or parent(s) (Datasets 15, 18, 21, and 24). If two caregivers were present and agreeable, both were interviewed. At random, 5 percent of families were contacted and re-interviewed (briefly) to assure reliability and validity. Each child's teacher was asked to fill out questionnaires on the child's behavior, social competence, and self-regulation at each wave (Datasets 16, 19, 22, and 25). Teachers were paid $10 per child for each assessment.
The sample of parents and children were participants in a family-focused group-based intervention from a 50 percent random sample of individual families with children entering first grade in six Chicago public schools. The sample of therapists was selected from mental health service agencies serving the communities in which the schools were located. The participating schools provided the principal investigators with the names, addresses, and phone numbers of all children attending kindergarten. Initial information was sent to all families. All information sent to families was translated into Spanish and included with English versions if the school served potentially Spanish speaking families. Following these letters, program staff contacted each family by phone or home visit. The research program was explained to families and informed consent was obtained. Eighth-grade tutors were nominated by their teachers. Providers were recruited and hired by their respective agencies, and trained by university personnel. There were a total of 1,178 participants in the study. 267 tutors were recruited and 15 individual therapists conducted groups. The principal investigators were able to recruit 383 subjects who completed the study, 190 were randomized to the treatment condition, and 155 consented to participate in the intervention. The Sample Data (Dataset 1) gives information on the 383 subjects who were recruited. The Twin ID Data (Dataset 2) gives identifying information for the 16 child participants who had twins in the study.
For the process and fidelity measurements, family attendance data (Dataset 3) is available for 2,058 cases, where each case represents a single parent's attendance at a single session (for up to 16 sessions). For the fidelity measurements, data are available for 61 parents who participated in session 3 (Dataset 4), 60 parents who participated in session 8 (Dataset 6), and 60 parents who participated in session 13 (Dataset 8). Fidelity data were provided by the therapists for 19 groups in session 3 and session 8 (Datasets 5 and 7) and 17 groups in session 13 (Dataset 9). Tutor Fidelity Data was gathered by supervisors evaluating 218 tutors at a total of 685 tutoring sessions (Dataset 10). For the process measurements, data are available from 86 parents (Dataset 11) at up to 3 family sessions each, resulting in a total of 184 cases. Process data on 83 children at up to 3 family sessions each were also provided by 11 therapists (Dataset 12), resulting in a total of 181 cases. Finally, process data are available from 224 tutors (Dataset 13) on 160 children at up to 5 tutoring sessions each, for a total of 906 cases. Data are not available for every participating parent, tutor, or therapist at each session because only parents who attended the sessions got the opportunity to complete process and fidelity measures; no makeup measures were administered. Also, not all 8th grade tutors or their supervisors completed tutoring process measures and the therapists were not required to complete the process assessments.
Due to non-participation and attrition among children, parents, and teachers during the span of the effectiveness evaluation, data are not available for every child in each component of the wave. The datasets corresponding to each wave of child interviews (Datasets 14, 17, 20, 23) have data on 380, 319, 308 and 318 children respectively. The datasets corresponding to each wave of parent interviews (Datasets 15, 18, 21, 24) have data regarding 383, 324, 315, and 322 children respectively. The datasets corresponding to each wave of the teacher questionnaires (Datasets 16, 19, 22, 25) have data on 379, 378, 337, and 347 children respectively.

Extent of Processing: 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:
Created variable labels and/or value labels.
Standardized missing values.
Checked for undocumented or out-of-range codes.
