Lay summary
The national mental health inquiry identified that New Zealand is not compliant with international obligations, particularly in terms of the continued practice of substitute decision-making as opposed to supported decision-making (SDM) (where individuals are supported to make their own decisions based on their will and preferences). However, there is little known about what and how interventions can support SDM being facilitated in practice. We will: (i) bring together key stakeholders from the numerous organisations that have pledged support for the activity proposed; and (ii) facilitate them to identify and then prioritise interventions in support of SDM that are considered as having the potential to lead to the greatest improvements in the lives of New Zealanders. Multi-disciplinary teams and plans to undertake the co-produced development and piloting of the identified and prioritised SDM interventions across various mental health care delivery settings will then be established as proposed health delivery research.
