Longitudinal relationships among exclusionary school discipline, adolescent substance use, and adult arrest: Public health implications of the school-to-prison pipeline.

PURPOSE: Exclusionary school discipline is an initiating component of the school-to-prison pipeline that is racialized and may lead to short- and long-term negative substance use and criminal legal outcomes. However, these impacts, and racial disparities therein, have not been well explored empirically at the individual-level.

PROCEDURES: We analyzed data from the National Longitudinal Study of Adolescent to Adult Health (1995-2009). We fit survey-weighted multivariable logistic regression models to estimate reciprocal relationships between exclusionary discipline and adolescent substance use, between these factors and subsequent exposure to the adult criminal legal system, and whether these relationships were modified by race or ethnicity.

RESULTS

We found that students reporting substance use had 2.07 (95% CI 1.57, 2.75) times greater odds of reporting subsequent school discipline, and students exposed to school discipline had 1.59 (95% CI 1.26, 2.02) times greater odds of reporting subsequent substance use. Substance use and school discipline were associated with 2.69 (95% CI 2.25, 3.22) and 2.98 (95% CI 2.46, 3.60) times the odds of reporting subsequent adult criminal legal system exposure, respectively. There was little evidence of effect modification by race/ethnicity.

CONCLUSIONS

Findings indicate that school discipline and substance use are reciprocally associated and have direct implications for adolescent health and future criminal legal system exposure.
