Identifying core mental health services required for adult justice-involved populations in Australia: a Delphi study

This study aimed to define required forensic mental health service types in Australia. A staged Delphi process was used, including: (1) reference group consultation to establish a set of core forensic mental health service types; (2) Delphi survey to seek consensus on identified service types and definitions among forensic mental health stakeholders in Australia; and (3) amendment of service definitions in response to survey feedback. Nine forensic mental health service types were identified. Consensus (>80% agreement) was achieved among Delphi respondents that all services were core components of an ideal forensic mental health system. These included forensic bed-based (acute, sub-acute, non-acute, non-acute community), forensic community, outreach, prison and court liaison services. The high levels of agreement on service types are notable considering legislative differences impacting on design and operation of services across jurisdictions. The findings could contribute to the evidence base required for needs-based planning of forensic mental health services.
