Evaluation of the Philadelphia Police School Diversion Program: Long-Term Outcomes and Sustained Impact, 2013-2020 (ICPSR 38271)
Schools are a primary referral source to the juvenile justice system, helping create and perpetuate the school-to-prison pipeline. Seeking to dismantle this pipeline in the city, the Philadelphia Police Department (PPD) partnered with the School District of Philadelphia (SDP) and the Philadelphia Department of Human Services (DHS) to develop and operate the Philadelphia Police School Diversion Program. Implemented in May 2014, all first-time offending youth aged 10 years or older who commit specified school-based minor misdemeanor or summary offenses on school property are diverted from arrest, referred to a Department of Human Services (DHS) social worker and community-based services, and face no consequences even if they decline services.
This evaluation examined long-term outcomes for diverted youth and sustained program impacts over five years. From a full sample of 3,616 diverted and arrested students, this study used a quasi-experimental design to compare data for diverted youth (quasi-experimental group; n = 1,281) and similar youth arrested in schools in the year before the program's implementation (quasi-control group; n = 531). PPD school police officers completed surveys regarding their knowledge and perceptions of the Diversion Program immediately before and after a training session held prior to its implementation, then on an annual basis through year five. A cost-benefit analysis of the program was conducted in partnership with the Vera Institute of Justice.
The data have been organized by analysis. Short-term analysis refers to two-year recidivism analyses and one-year child welfare involvement, and covers the full and quasi-control arrested samples and youth diverted in school years 2014-2015, 2015-2016, and 2016-2017. Long-term analyses include four-year graduation/drop-out, five-year recidivism analyses, and five-year child welfare involvement, and covers the full and quasi-control arrested samples and youth diverted in school year 2014-2015.
Short- and long-term recidivism outcome data (DS1 and DS2), police survey data before and after program implementation (DS3), and cost-benefit analysis tables (DS9) are included in this collection. Please refer to the User Guide for details on how to acquire additional data from SDP and DHS and steps to create the full analytic files for academic-related and child welfare involvement outcomes.
Impact Evaluation of Complementarities Between Positive Behavioral Interventions and Supports (PBIS) and Restorative Justice, Maryland, 2018-2021 (ICPSR 38863)
Across the United States (U.S.), school districts have grappled with how to create safe community- and achievement-oriented schools and how to ensure the necessary discipline is applied transparently, fairly, and without bias. Two programs that many schools have turned to in order to achieve these goals are Schoolwide Positive Behavioral Interventions and Supports (PBIS) and Restorative Justice (RJ). PBIS is an evidence-driven schoolwide behavioral management approach that aims to outline clear expectations for students and to cultivate shared norms and practices across classrooms and school spaces. PBIS has become a popular approach in schools and districts: as of 2020; over 19,000 schools in the U.S. have implemented PBIS.
A second program, Restorative Justice (RJ), has grown in popularity in recent years. RJ typically focuses on restorative relationship building between affected parties, peaceful reconciliation, and non-punitive approaches to rectifying harm, using a structured circle discussion format. RJ schools use both community circles, designed to build a safe space for students and staff to share and listen to each other, and restorative circles, designed to share perspectives on and redress a behavioral issue.
Working with a large school district in a mid-Atlantic state, researchers set out to test whether these two programs substitute for or complement each other. In partnership with the school district researchers conducted two separate school-level randomized controlled trials (RCTs). The first RCT (RCT 1) sought to uncover the marginal impact of RJ by adding the program to a set of randomly selected schools that were already implementing PBIS. The second RCT (RCT 2) was designed to discover the impact of introducing both programs together into schools that had neither program at baseline. Researchers conducted student and staff surveys to collect measures of school climate, teacher logs to record program implementation, and researchers also received administrative data from the district on student test scores, teacher and student absences, student disciplinary infractions, and school costs.
There is growing evidence of the effectiveness of each of these programs in isolation. A recent meta-analysis of 32 experimental and quasi-experimental impact studies of PBIS found that PBIS reduced disciplinary exclusions and problem behavior and increased academic achievement. The findings were statistically significant and showed small to medium effect sizes. Individual studies have found that PBIS reduces the use of office disciplinary referrals and other exclusionary disciplinary measures (including the use of in-school and out-of-school suspensions), while improving student behavior and attitudes across school levels. Individual studies show variable--some statistically significant and some null--impacts on academic outcomes.
The empirical evidence on the effect of RJ in U.S. schools is more limited, with little rigorous casual evidence published to date. Based on patterns across rigorous and non-rigorous research, restorative justice is associated with decreases in suspension rates and disciplinary disparities, improved student behavior, and improved school climate and relationships.
Institutional Pathways: Dynamics and Characteristics of System Service Use by Serious Adolescent Offenders, Arizona and Pennsylvania, 2000-2010 (ICPSR 36860)

This study is a secondary analysis (syntax only, no data) of Research on Pathways to Desistance [Maricopa County, AZ and Philadelphia County, PA]: Subject Measures, 2000-2010 (ICPSR 29961) and Research on Pathways to Desistance [Maricopa County, AZ and Philadelphia County, PA]: Calendar Data, 2000-2010 [Restricted] (ICPSR 32282).
The purpose of this study was to further existing knowledge of juvenile justice intervention and how juvenile justice intervention is related to positive outcomes during the transition to adulthood. This study examines three main aims using data from the Pathways to Desistance study, which followed a sample of serious adolescent offenders for seven years to examine the desistance process. First, trajectories of secure institutional placement for serious offenders during the study period were identified. Second, trajectories of gainful activities for serious adolescent offenders during the study period were identified. Gainful activities were defined as working or attending school. Third, factors associated with turning points in the gainful activities trajectories were explored. In the course of estimating the gainful activities trajectories, there appeared to be a key moment, around year 3, where multiple trajectories with moderate levels of engagement in gainful activities diverged. Together, these three aims will inform how juvenile justice intervention is related to positive outcomes during the transition to adulthood and identify factors that may be related to positive outcomes and critical turning points in the trajectories of serious adolescent offenders.
Group differences were examined by testing bivariate differences in a broad range of variables: demographic variables (gender, age, and race/ethnicity); study site and year of interview; characteristics of prior service receipt at baseline (location and orientation); school, family and neighborhood characteristics; characteristics of the offense and offense history; individual factors (mental health and substance use symptoms); and risk scores.

Users who request these restricted data should first review the documentation available from NAHDAP (user guide and frequency codebooks) and from the Pathways Website (domain content codebooks). This review will help determine which specific datasets will be needed for your project. The "Research Description" in ICPSR's Data Access Request System (IDARS) must include a specific explanation of why you need each topic domain selected on the "Data Selection" page in IDARS. Most projects should only require one reference period per topic domain being requested. Data requests for all reference periods within a given domain will not be approved without a satisfactory explanation of why all of the reference periods are required for your project. Since the Calendar data collection is very extensive and Restricted Data Use Agreements are only for 2 years, data requests are not expected to need the entire Calendar data collection.
The Pathways to Desistance study was a multi-site study that followed 1,354 serious juvenile offenders from adolescence to young adulthood in two locales between the years 2000 and 2010. Enrolled into the study were adjudicated youths from the juvenile and adult court systems in Maricopa County (Phoenix), Arizona (N=654) and Philadelphia County, Pennsylvania (N=700).
Respondents were enrolled and baseline interviews conducted from November 2000 to January 2003. Follow-up interviews were then scheduled with the respondents at 6, 12, 18, 24, 30, 36, 48, 60, 72 and 84 months past their baseline interview.
The enrolled youth were at least 14 years old and under 18 years old at the time of their committing offense and were found guilty of a serious offense (predominantly felonies, with a few exceptions for some misdemeanor property offenses, sexual assault, or weapons offenses).
Research on Pathways to Desistance [Maricopa County, AZ and Philadelphia County, PA]: Collateral Measures, 2000-2004 (ICPSR 32881)
The Pathways to Desistance study was a multi-site study that followed 1,354 serious juvenile offenders from adolescence to young adulthood in two locales. Enrolled into the study were adjudicated youths from the juvenile and adult court systems in Maricopa County (Phoenix), Arizona (N=654) and Philadelphia County, Pennsylvania (N=700) from 2000 through 2010.
This study looks at interviews conducted with the collateral informants who participated in the study. The collateral informants were nominated by the main study participant and represented individuals who "knew the study participant well". At the interview baseline the collateral informant was usually a biological parent. During the three follow-up interviews the majority of collaterals were a friend. Collateral informants could also be a sibling, significant other, or relative. Collaterals were asked questions in regards to the main study participant's life, allowing for comparison between responses provided by two sources. A baseline interview was conducted with the collateral after the baseline interview took place with the main participant. Additional waves of follow-up with collaterals took place at 12, 24, and 36 months. A collateral report is not present for all of the main study participant interviews across waves (see response rate below).

The current Collateral Measures study primarily consists of the calculated scores from constructs asked about during the interview, but the individual scale items were withheld at that time. These additional datasets contain those individual items plus the calculated scores. These variables are typically consistent across the waves that the scale was asked about during the course of the entire project. Most of the files contain variables from all four waves of data collection. The table in the front of the User Guide will list which waves are present in each data file.
Research on Pathways to Desistance [Maricopa County, AZ and Philadelphia County, PA]: Release Measures, 2000-2010 [Restricted] (ICPSR 34488)
The Pathways to Desistance study was a multi-site study that followed 1,354 serious juvenile offenders from adolescence to young adulthood in two locales between the years 2000 and 2010. Enrolled into the study were adjudicated youths from the juvenile and adult court systems in Maricopa County (Phoenix), Arizona (N=654) and Philadelphia County, Pennsylvania (N=700).
The Release data portion of the Pathways study contains information from 1,130 interviews ("release interviews") reflecting the youths' perceptions regarding various aspects of the residential experience and institutional environment (e.g., accounts of program operations and services provided, ratings regarding the participant's feelings of his or her safety in the facility). The release interview was conducted within 30 days prior to or after release from a facility and in a separate session apart from the time point interview. This was done to minimize the burden on the research participant and to ensure adequate attention to institutional ratings. The restricted time period within which to conduct the release interview reduced the likelihood that intervening events and experiences would skew the participant's recall of the stay.
Study participants could contribute more than one release interview, depending upon the number of institutional placements he/she had over the seven-year follow-up period. The current release data reflects ratings from 686 unique individuals. It should be recognized that not every institutional stay for every youth produced a release interview. On the basis of the number of reported institutional stays in the sample, it is estimated that a release interview was obtained for approximately 54 percent of the total number of residential stays experienced by study participants. Release interviews were missed if the research interviewer was not aware of the institutional stay (e.g. it occurred between time point interviews) or if the interviewer only became aware of the institutional stay at a point that was too late to schedule a release interview within the required window surrounding the release date.
The 686 individuals reflected in the release data represent 51 percent of the Pathway study participants (n=1,354) and 56 percent of Pathways participants who had a least one institutional stay (n=1,234; 120 Pathways youths had no institutional stays). On average, these 686 youths had 1.6 interviews. The number of interviews per unique person ranges from one to eight.

Research on Pathways to Desistance [Maricopa County, AZ and Philadelphia County, PA]: Subject Measures, 2000-2010 (ICPSR 29961)
The Pathways to Desistance study was a multi-site study that followed 1,354 serious juvenile offenders from adolescence to young adulthood in two locales between the years 2000 and 2010. Enrolled into the study were adjudicated youths from the juvenile and adult court systems in Maricopa County (Phoenix), Arizona (N=654) and Philadelphia County, Pennsylvania (N=700).
Respondents were enrolled and baseline interviews conducted from November 2000 to January 2003. Follow-up interviews were then scheduled with the respondents at 6, 12, 18, 24, 30, 36, 48, 60, 72 and 84 months past their baseline interview.
The enrolled youth were at least 14 years old and under 18 years old at the time of their committing offense and were found guilty of a serious offense (predominantly felonies, with a few exceptions for some misdemeanor property offenses, sexual assault, or weapons offenses).
The baseline interview was conducted within 75 days of the youth's adjudication hearing. For youths in the adult system, the baseline interview was conducted within 90 days of either (a) the decertification hearing in Philadelphia, a hearing at which it is determined if the case will remain in adult court or if it will be sent back to juvenile court; or (b) the adult arraignment hearing in Phoenix, the point in the Arizona adult system at which charges have been formally presented.
The aims of the investigation were to identify initial patterns of how serious adolescent offenders stop antisocial activity, to describe the role of social context and developmental changes in promoting these positive changes, and to compare the effects of sanctions and interventions in promoting these changes. The larger goals of the Pathways to Desistance study were to improve decision-making by court and social service personnel and to clarify policy debates about alternatives for serious adolescent offenders. The study relied primarily on self-report information from study participants.
Each wave of data collection covered six domains: (1) background characteristics (e.g., demographics, academic achievement, psychiatric diagnoses, offense history, neurological functioning, psychopathy, personality), (2) indicators of individual functioning (e.g., work and school status and performance, substance abuse, mental disorder, antisocial behavior), (3) psychosocial development and attitudes (e.g., impulse control, susceptibility to peer influence, perceptions of opportunity, perceptions of procedural justice, moral disengagement), (4) family context (e.g., household composition, quality of family relationships), (5) personal relationships (e.g., quality of romantic relationships and friendships, peer delinquency, contacts with caring adults), and (6) community context (e.g., neighborhood conditions, personal capital, and community involvement). Information about the measures used to capture this information can be found on the Pathways to Desistance website.
