Knowing so much, yet knowing so little: a scoping review of interventions that address the stigma of mental illness in the Canadian context

Abstract

Stigma can have detrimental effects on the health and wellbeing of individuals living with a mental illness. This scoping review describes the nature, range, and extent of intervention research aimed at reducing public and self-stigma of mental illness in the Canadian context. The review was guided by Arksey and O’Malley’s framework. A search of databases and relevant websites identified 35 primary studies. Most studies used quantitative research methods and included predominantly youth or middle-aged adults, women, and white Canadian-born people. Guided by different conceptualizations of stigma, direct or indirect contact, education, and advocacy-focused interventions, aimed to provide information, and/or develop skills to address self and public stigma. Most studies evaluated interventions’ effectiveness short-term. Of the few studies that followed-up participants long-term, some were able to reduce stigmatizing attitudes post-intervention, however, these targeted only specific groups such as students or health care professionals. Lack of diversity among the samples, and limited evidence of long-term effectiveness of interventions, were some of the studies’ limitations. What is currently known about interventions aimed at reducing the stigma of mental illness in the Canadian context is not informed by research among vulnerable groups, such as people living with a mental illness, older adults, immigrants, and people of diverse ethnic backgrounds. Interventions that are informed by clear conceptualizations of stigma and rigorously evaluated in a range of ethno-cultural groups would create a knowledge base that is useful for policy-makers, community leaders, and agencies serving various ethnic communities in Canada.
