“What works” with mentally disordered offenders

Treatment and rehabilitation of mentally disordered offenders has traditionally been a function of high security hospitals, but is increasingly based in community settings. Evidence for the effectiveness of psychological interventions remains scarce, and for secure hospitals, is limited to demonstrations of short-term effects using a conventional range of behavioural and cognitive–behavioural procedures. Some findings support the use of directive community programmes in meeting the needs of public safety and improved reintegration of the individual. Long-term services are required, and more complex psychological contributions are needed to meet the multiple needs of this client group.
