The importation model mediated: New evidence for security threat group in the prediction of prison misconduct

This study explores the importation model's role in predicting prison misconduct, emphasizing the mediating effect of security threat group membership. Our analysis draws upon archival data from 636 individuals on death row in California. Structural equation modeling examined relationships between pre-prison characteristics-such as psychopathy, age at first arrest, and prior prisons sentences-and prison misconduct. Findings reveal that security threat group membership significantly mediates the impact of psychopathy and age at first arrest on misconduct, accounting for 60 % and 79 % of their respective effects. Moreover, security threat group membership is strongly associated with institutional misconduct, highlighting its role as a critical factor in prison disorder. The results suggest that pre-prison experiences and security threat group involvement should be integral to risk assessments and management strategies of correctional clients. These insights contribute to understanding prison dynamics and offer practical guidance for improving institutional security and reducing misconduct through targeted interventions addressing security threat group activities.
