Objective: To elicit informal caregiver feedback about an mHealth resource and it's potential as a nurse-delivered intervention for caregiver communication support.; Data Sources: Four focus groups with current oncology caregivers that involved caregiver use of the resource and response to a video demonstrating the resource as a nursing intervention. A brief assessment of the resource was collected for triangulation of data.; Conclusion: Caregivers rated the resource as overwhelmingly positive and reported that use of the resource gave an increased sense of preparedness. Caregivers shared ideas for future expansion of the resource, highlighted the need for user-responsive design, and described the need for a caregiver-centered tool.; Implications For Nursing Practice: Communicating complex terminology relating to treatment, side effects, and symptoms requires resources to meet health literacy needs. A nursing protocol for using the resource is provided based on feedback collected from caregivers.
