The long-term consequences of school suspension and expulsion on depressive symptoms

Exposure to exclusionary discipline has been tied to several deleterious outcomes in adulthood, including contact with the criminal legal system. While this work provides interesting insight into the long-term consequences tied to this form of school punishment, few have attempted to consider whether and how, exclusionary discipline practices, in particular, school suspension and expulsion shape mental health patterning over the life course. Using panel data from the National Longitudinal Study of Adolescent to Adult Health, we contribute to this body of literature by examining whether exposure to school suspension or expulsion shapes depressive symptom trajectories from adolescence to adulthood. Results from our mixed-effects linear growth curve models demonstrate both forms of exclusionary discipline play a significant role in depressive symptom trajectories. We find suspended and expelled youth exhibit significantly higher depressive symptoms in adolescence when compared to their counterparts with no history of suspension or expulsion. Results also show age variation in depressive symptom trajectories by history of exposure to exclusionary discipline. Specifically, results show the depressive symptoms gap between disciplined and non-disciplined youth slightly dissipates as youth age into early adulthood, but as individuals begin to transition out of this stage of the life course, the gap in depressive symptoms widens substantially. Results carry implications for how punitive disciplinary practices in schools shape mental health from adolescence to adulthood.
