Abstract
Abstract
Drawing upon the principles of social identity theory, existing literature, and our initial findings from
family caregiver (FCG) online support groups (OSGs), our objective is to identify fundamental
facilitator communication strategies that promote safe communication engage participants, and
strengthen mechanisms of action (MOAs) within OSGs, ultimately enhancing health outcomes for
hospice FCGs.
Our pioneering initiative, Communication and Hospice Online with Optimal Support and Engagement
(CHOOSE) is backed by compelling evidence highlighting the critical role of
facilitator communication in reinforcing MOAs (a shared identity, social support, and social networks) in OSGs.
Preliminary research underscores the transformative power of these MOAs in improving health outcomes for
FCGs, yet current studies lack generalizability and statistical robustness. CHOOSE represents the first major,
multisite, rigorously designed, and theoretically informed OSG intervention explicitly tailored for hospice FCGs
of cancer patients. We aim to strengthen MOAs to enhance FCG well-being, reduce depression and
anxiety, improve quality of life, and diminish loneliness. By advancing this critical research, we seek
to provide a well-founded, evidence-based solution to the urgent needs of FCGs, making a significant
impact on their health and well-being. We have outlined the following study aims:
Aim 1. Determine the effect of the CHOOSE intervention on FCGs’ health outcomes compared to usual OSGs and usual
hospice care.
Aim 2. Examine direct and mediational relationships between CHOOSE participation, MOAs, and health outcomes.
Aim 3. Explore the relationship between facilitator communication strategies and the FCG experience of the MOA to allow
for future calibration of the intervention
