Out and Down

Abstract

Psychiatric disorders are unusually prevalent among current and former inmates, but it is not known what this relationship reflects. A putative causal relationship is contaminated by assorted influences, including childhood disadvantage, the early onset of most disorders, and the criminalization of substance use. Using the National Comorbidity Survey Replication (N = 5692), we examine the relationship between incarceration and psychiatric disorders after statistically adjusting for multidimensional influences. The results indicate that (1) some of the most common disorders found among former inmates emerge in childhood and adolescence and therefore predate incarceration; (2) the relationships between incarceration and disorders are smaller for current disorders than lifetime disorders, suggesting that the relationship between incarceration and disorders dissipates over time; and (3) early substance disorders anticipate later incarceration and other psychiatric disorders simultaneously, indicating selection. Yet the results also reveal robust and long-lasting relationships between incarceration and certain disorders, which are not inconsequential for being particular. Specifically, incarceration is related to subsequent mood disorders, related to feeling "down," including major depressive disorder, bipolar disorder, and dysthymia. These disorders, in turn, are strongly related to disability, more strongly than substance abuse disorders and impulse control disorders. Although often neglected as a health consequence of incarceration, mood disorders might explain some of the additional disability former inmates experience following release, elevating their relevance for those interested in prisoner reintegration.
