Depression is a significant problem in care partners of people living with dementia; despite the expansion of options for accessing evidence-based treatments, most care partners of people living with dementia are not screened for depression and do not receive treatment. The objective of this project is to identify a screening method for depression that is feasible and acceptable to care partners and to adapt an innovative pathway to online evidence-based treatment for depression (iPath\*D) as a means of increasing mental health literacy, screening rates and treatment access for care partners of people living with dementia. The results are expected to have a major positive impact by providing proof-of-principle for the use of an online pathway to evidence based treatment with the potential for reaching an unprecedented number of care partners who have unmet mental health needs.
