Aims: We aim to establish the feasibility and acceptability of the Tele‐STELLA (Support via Telehealth: Living and Learning with Advancing Alzheimer's Disease and Related Dementias) intervention. We will also assess the efficacy of the intervention in reducing the frequency of behavioural symptoms of dementia as well as family Care Partner reactivity to the symptoms. Design: This is a multi‐component, quasi‐experimental study that focuses on facilitating effective management of behavioural symptoms that occur in the later stages of dementia.
