OBJECTIVES/GOALS: To evaluate the feasibility, acceptability, and appropriateness of a 1:1 peer-delivered psychosocial support intervention to family caregivers of hospice patients with cancer, and determine a range of potential effects of the intervention on psychological distress symptoms and perceptions of the caregiving experience. METHODS/STUDY POPULATION: Quantitative and qualitative data were collected from hospice caregivers of cancer patients who participated in a non-controlled pilot feasibility trial of a 1:1, peer-delivered psychosocial intervention called Peer Caregiver Navigation (PCN). The purpose of this study was to evaluate the feasibility, acceptability, and appropriateness of delivering PCN to hospice family caregivers of cancer patients, and to determine a range of potential effects of PCN on caregivers’ anxiety symptoms, depressive symptoms, self-efficacy, and benefit finding. Qualitative data were analyzed using deductive thematic analysis. For our study outcomes, we used both parametric and nonparametric t-tests to examine mean differences between outcomes at baseline and midpoint, and baseline and endpoint. RESULTS/ANTICIPATED RESULTS: The findings demonstrate that Peer Caregiver Navigation (PCN) is acceptable, appropriate, and feasible to deliver to hospice family caregivers of cancer patients. Appropriateness of our selected target outcomes was determined by confirming expected measurement change in depressive symptoms (lower), anxiety symptoms (lower), benefit finding (higher), and self-efficacy (higher). Exit interviews revealed that participants responded favorably to our selected measures for these outcomes and to our data collection time intervals. Moreover, recruitment and consenting processes, survey completion rates, and attrition outcomes (i.e., study exit due to active withdrawal vs. patient death) were analyzed to inform recruitment and retention feasibility for future studies. DISCUSSION/SIGNIFICANCE: Peer Caregiver Navigation (PCN) was determined to be feasible, acceptable, and appropriate to hospice family caregivers of patients with cancer. Moreover, PCN has the potential to improve caregivers' symptoms of psychological distress by providing them much needed psychoeducation, coping skills training, and emotional support.
