Criminal history's expiration date: Evidence of prediction decay (Forthcoming)

Criminal history's expiration date: Evidence of prediction decay (Forthcoming)

Criminology 2026

Criminal history is a well-established predictor of future offending, yet recidivism risk declines with time. Research has struggled to reconcile this tension as criminal history is often treated as a static indicator of risk, while desistance is commonly inferred rather than directly modeled. Using a five-state population of criminal charges spanning forty years (N = 16,594,838; person-year observations = 746,396,524), we model recidivism prediction decay following a prior charge.

Longitudinal patterns of compliance in drug treatment courts: A group-based trajectory modeling approach

Longitudinal patterns of compliance in drug treatment courts: A group-based trajectory modeling approach

Crime & Delinquency 2026

Drug treatment courts (DTCs) rely on structured supervision and treatment to curb substance use among justice-involved individuals. Using group-based trajectory modeling, this study identifies early-phase patterns of in-program substance use among 320 adult DTC participants, measured through positive drug tests across the first 90 days.

Know your (secondary) data inside and out: Missing data and measurement in the Youth Psychopathic Traits Inventory from the Pathways to Desistance dataset

Know your (secondary) data inside and out: Missing data and measurement in the Youth Psychopathic Traits Inventory from the Pathways to Desistance dataset

Crime & Delinquency 2026

This study examines how undocumented item-level missingness during scale construction of the Youth Psychopathic Traits Inventory (YPI) within the Pathways to Desistance dataset accessed through ICPSR can shape the measurement properties and downstream use of the measure in secondary analysis.

Selection and facilitation: Is the gang membership-psychopathic traits link a product of individual differences, social influences, or both?

Selection and facilitation: Is the gang membership-psychopathic traits link a product of individual differences, social influences, or both?

Journal of Research in Crime and Delinquency 2026

The issue of psychopathology among gang populations is controversial. Building off an interdisciplinary theoretical basis that adapts a tripartite theoretical model (i.e., selection, facilitation, and enhancement) on the gang membership-offending link (Thornberry et al. 1993) to the mixed positions on the gang membership-psychopathic traits relationship, this study tests selection and facilitation models.

A methodological template for the next generation: Redesigning the STRONG-R needs assessment

A methodological template for the next generation: Redesigning the STRONG-R needs assessment

Journal of Criminal Justice 2025

Using 111,731 reentrants assessed via the Static Risk Offender Needs Guide–Revised (STRONG-R), we redesigned the needs assessment and establish construct validity via exploratory, confirmatory, multi-group confirmatory factor analysis, correlation, receiver operating characteristics, and regression techniques.

Nebraska Department of Correctional Services classification and crowding project report

Nebraska Center for Justice Research 2024

In response to growing concerns among stakeholders and policy makers regarding crowding in Nebraska correctional facilities, the Nebraska Department of Correctional Services (NDCS) partnered with the Nebraska Center for Justice Research (NCJR) to examine causes and solutions.

Gang affilitation and prisoner reentry: Discrete-time variation in recidivism by current, former, and non-gang status

Gang affilitation and prisoner reentry: Discrete-time variation in recidivism by current, former, and non-gang status

Journal of Research in Crime and Delinquency 2021

Reentry experiences for the 600,000 people released annually from federal and state prisons differ vastly. We contend that gangs, which rose to prominence alongside mass incarceration, are an overlooked source of variation in reentry experiences.
