Objective: Military family caregivers (MFCGs) are a growing population with well-being and quality of life (QOL) challenges. New technologies can help meet their needs while minimizing disruption to caregiving responsibilities. Preliminary research needs to address intervention implementation challenges before larger-scale efficacy studies are conducted. This study aimed to evaluate the feasibility of implementing an avatar-based intervention and preliminarily investigate outcomes.; Methods: One-hundred twenty-four MFCGs were recruited to participate in this feasibility study. Sixty-four MFCGs completed the intervention. Data were analyzed using repeated-measures analysis of variance to assess 3- and 6-month differences.; Results: Meeting the a priori goal of 50 MFCGs completing the program supported feasibility. Preliminary results indicated significant reductions in depression, anxiety, and somatic symptoms, and significant improvements in physical health and overall QOL.; Conclusions: Findings support for the feasibility of implementing an avatar-based intervention for MFCGs and present promising findings related to improving caregiver well-being and overall QOL.
