Abstract 4135780: Predictors of Engagement in a Coaching Intervention for Heart Failure Caregivers

Background: Even the best intervention will not be effective without engagement in the experience. We developed and tested a virtual health coaching intervention ("ViCCY”, Virtual Caregiver Coach for You) for informal caregivers of patients with HF in a RCT. Of the 125 caregivers in the intervention group, completion rates varied (mean 6 ± 4 sessions, median 9; 21% no sessions). The aim of this study was to identify factors associated with intervention engagement defined as receipt of ≥8 of 10 intervention sessions over a 6-month period based on core intervention content. Methods: This explanatory sequential mixed methods study was conducted in two phases. First quantitative data were analyzed with respect to number of completed sessions, sociodemographics, and the Credibility-Expectancy Questionnaire measuring expectations regarding intervention effectiveness. We used multivariable logistic regression to quantitatively identify salient predictors of caregivers’ intervention engagement. Then, based on the number of sessions completed, 24 caregivers assigned to ViCCY were interviewed to explore individual, family, community, and societal factors associated with intervention engagement. Transcribed interviews were coded using content analysis. Results: Each one hour increase in hours caregiving was associated with reduced odds of completing ≥8 sessions. Race other than White and income insufficient to make ends meet were associated with reduced odds of completing ≥8 sessions. Each unit increase in intervention credibility was associated with increased odds of completing ≥8 sessions. Interviews with participants who completed some sessions revealed common challenges such as the patient’s HF progression and life events including caregiver health issues, balancing multiple responsibilities, and interpersonal issues. Reluctance to accept help from an unfamiliar individual through a virtual network and perceiving additional resources as burdensome also hindered participation. Practical issues such as finding a suitable space for virtual meetings and scheduling conflicts interfered. In those who did not complete any sessions, the main reason for non-engagement was misunderstanding of what to expect in the intervention. Conclusions: The daily lives of HF caregivers are influenced by caregiving demands exacerbated by social determinants of health. These issues may reduce the capacity of caregivers to accept help and ultimately act as a barrier to program engagement.
