Recent research suggests that imprisonment may increase subsequent levels of offending, but it is not clear why this is the case. Drawing on general strain theory (GST), this study examines whether exposure to the strains associated with imprisonment affects recidivism. These strains include direct victimization, the perception of a threatening prison environment, and hostile relationships with correctional officers. Consistent with GST, data from a sample of 1,613 recently released inmates in Ohio suggest that certain types of these strains do increase the likelihood of recidivism. These results challenge specific deterrence theory and claims by public officials that painful prisons will reduce reoffending.
