Professionals' views and experiences in supporting decision-making involvement for people living with dementia.

Professionals conceptualised their role in providing support for decision-making through the lens of their own profession. Differences in positioning on the continuum of 'individualist advocacy' through to 'relational practice' had practical implications for capacity assessment, engaging with persons with impaired decision-making capacity, and the inclusion of supporters and family members in decision-making processes. Further progress in implementing supported decision-making (including through law and policy reform) will require an understanding of these inter-professional differences in perceived roles relating to the practice of providing decision-making support.
