Caring for an individual with cancer can be physically and emotionally draining and finding an effective intervention that supports caregivers is needed. The purpose of this systematic review was to investigate the psychological and biological effects of mind-body therapies for informal caregivers of individuals with cancer.

A literature search was completed using 6 databases (PubMed, CINAHL, Cochrane, PsycINFO, PEDro, and OTSeekers) and 4 gray literature databases (MedNar, NY Academy of Medicine Grey Literature Report, WorldCat Dissertations and Theses, and Proquest Psychology). Studies were included if they were randomized controlled trials published after 2010; participants were informal caregivers of individuals with cancer; and the main intervention was yoga, meditation, progressive relaxation therapy and guided imagery, mindfulness therapy, tai chi, breathing exercises, qigong, or visual imagery. The researchers completed title, abstract, and full-text screens using the selection criteria. Data were synthesized descriptively according to the different types of interventions. The Physiotherapy Evidence Database (PEDro) scale was used to critically appraise the final articles.

There were a total of 11 articles included in this systematic review. There is evidence that certain mind-body therapies can have a positive effect on well-being, anxiety, and fatigue but not mindfulness or stress. One study found significant improvements in biological markers.

Medical professionals should consider recommending mind-body therapies, especially to informal caregivers who present with anxiety, fatigue, and impairments in well-being. The major limitation in this review is based mostly on fair quality evidence.
