"I used to call him a non-decision-maker - I never do that anymore": parental reflections about training to support decision-making of their adult offspring with intellectual disabilities.

Purpose: A rights perspective proposes supported decision-making as an alternative to substitute decision-making. However, evidence about supported decision-making practice is limited. Our aim was to build evidence about building the capacity of decision supporters.

Methods: Eighteen parents of people with intellectual disabilities were trained in decision support using the La Trobe Support for Decision-making Practice Framework. Data from repeated semi-structured interviews and mentoring sessions were used to capture parental reflections on the value of training.

Results: The training acted as a catalyst for parent self-reflection and the Framework prompted them to adopt a more deliberative approach to supporting decision-making. Some parents perceived increased confidence of their adult offspring in expressing preferences resulting from their own changed approach.

Conclusions: This study demonstrates the efficacy of this Framework and evidence-based training in building the capacity of parental decision supporters to be consistent with the rights paradigm. IMPLICATIONS FOR REHABILITATIONThe La Trobe Support for Decision-making Practice Framework is an evidence-based approach to decision support practice with an accompanying set of free online resources which can be used by individual practitioners or programs to inform their practice and build the capacity of supporters.Parents of adults with intellectual disabilities value training in the La Trobe Support for Decision-making Practice Framework, which they consider helps to develop their decision support skills and self-reflection.Parents also value individual mentoring following training to assist them to apply the principles of the practice framework to the everyday support for decision-making they provide to their adult son or daughter.Training in support practice should be accompanied by individual mentoring or other strategies to assist parents of adults with intellectual disabilities to discuss and solve the difficult issues they confront in providing decision support more aligned to the rights paradigm.
