1.	Evaluate caregiver’s specific direct and indirect impact on more focused areas of patient attitudes, knowledge, and health behaviors (e.g. physical symptom management, advance care planning) using dyadic analysis techniques (e.g. Actor-Partner Interdependence Model).
2.	Explore the characteristics, quality, and impact of different caregiving strategies have on promoting their care recipients’ health behaviors over time.
3.	Identify the underlying mechanisms of caregiver characteristics (e.g. strain, mood, relationship history), distinct patient health behaviors (as a process or proximal outcome), and patient quality of life and health (as a primary or distal outcome).
4.	Examine benefits and harms of caregivers and the quality of their care on patients’ psychological health and relationships, quality of life, and healthcare utilization.
