ABSTRACT Death by suicide is the leading cause of death in American jails. Closely linked with suicides are self-injurious thoughts and behaviors. Even with this knowledge, the risk factors for self-harm ideation and self-harm behaviors have received little empirical work within a jail population. This study couples an integrated importation and deprivation model with an ideation-to-action approach to examine environmental and psychological correlates of self-harm ideation and self-harm behaviors among a sample of 231 individuals incarcerated in jail. Results from the ordinary least squares regression models demonstrate that both deprivation (institutional misconduct) and importation (hopelessness) factors are important when identifying self-harm ideation and self-harm behaviors. In addition, the results of this test of the integrated model offer a proposed new direction for integrated theory testing. Finally, a discussion of policy implications and actionable programs are suggested.
