Current strategies in the reduction of stigma among caregivers of patients with mental illness: a scoping review

Mental healthcare and wellness are a global concern and have increasingly become an essential service and priority from a human rights perspective. However, negative attitudes towards mental health, such as stigmatisation and discrimination from communities and family members, continue to pose challenges for deinstitutionalisation and home care of mentally ill persons. This study aimed to review the literature on the content and implementation methods of stigma reduction interventions for family/community caregivers of patients with mental illness to inform the development of an anti-stigma intervention for such caregivers in low- and middle-income countries like South Africa. A scoping literature review was conducted of English language studies published from 2008 to 2019 in peer-reviewed journals, using established guidelines for the study objectives. Primary interventions targeting caregivers of mental health patients were searched from PsycINFO, ScienceDirect, CINAHL, and Medline. In total, nine full-text articles were extracted for inclusion in the review, indicating a scarcity of literature on anti-stigma interventions aimed at primary caregivers of mental health patients. Interventions varied in terms of educational content, duration, delivery methods, and sample sizes. Intervention delivery was primarily through face-to-face, telephone, and online methods. Anti-stigma interventions for caregivers of patients with mental illness are varied and show positive short-term impacts on mental health stigma reduction among family caregivers. The evolution of health systems is a feasible approach towards integrating learning and trials that are needed to assess long-term impacts.
