Purpose: This review aims to determine the effectiveness of mindfulness‐based interventions (MBIs) and educational interventions (EIs) as supportive care for family caregivers (FCs) of patients with cancer. Design and Methods: Review was conducted following PRISMA guidelines. The search protocol was performed using EBSCO, Google Scholar, and Science Direct for the studies published between 2007 and 2017. Findings: Little evidence is available on the usefulness of MBIs among FCs of patients with cancer. However, the available evidence supports that MBIs have the potential to enhance overall well‐being and reduce the burden for FCs. EIs have shown positive outcomes on some aspects of well‐being and reducing the burden. Practice Implications: The findings provide preliminary support for effectiveness of MBIs and EIs as a supportive care for FCs.
