Objectives: In home-based care for severely ill patients, family caregivers’ contributions are crucial. This study aimed to explore how a web-based psychoeducational intervention influences family caregivers’ experiences in addressing challenges while caring for a patient with life-threatening illnesses during specialized home care.

Methods: This qualitative study undertook semi-structured interviews with family caregivers of patients with life-threatening illness receiving specialized home care. Family caregivers participated in a randomized controlled trial evaluating a psychoeducational intervention delivered through a website. Interviews were performed with 17 family caregivers; 13 spouses, 2 adult children, 1 parent, and 1 sibling, and analyzed using qualitative content analysis.

Results: The results indicate that the intervention resonated with the family caregivers’ situation which gave them comfort and awareness. It inspired self-reflection on the caregiver role that provided new insights and encouraged communication with the patient. The intervention prepared family caregivers for the patient’s progressing illness and death. While preparing was a help for some, others did not feel ready to face this, which led them to avoid parts of the website.

Significance of results: This psychoeducational web-based intervention guided family caregivers as they addressed challenges in caregiving and prepared for the future, and they valued having access to such an intervention. In a time of decreasing healthcare resources, web-based support may be a useful alternative to in-person interventions. It is important to continue developing, evaluating, and implementing web-based interventions to meet the needs of family caregivers.
