1.1. HOW WILL THE RESULTS OF THIS TRIAL BE USED? This trial proposes an intervention designed to be applicable within Canadian healthcare, as modeled in Quebec urban areas. The study will use some aspects of the participatory research model and integrated knowledge translation, including input and feedback from national and local stakeholders in aging and mental health. An Advisory Committee has been formed, with members from various stakeholder groups: Canadian Coalition for Seniors' Mental Health, Action on Mental Illness Quebec. Input will be sought from these individuals and groups prior to, during, and after the trial, with the goal of optimizing use of the results in a collaboratively-developed strategic action plan for implementation of results for submission to stakeholders at national, provincial, and regional levels across Canada.
