SETTING
While substantial progress is being made in tuberculosis (TB) control, the success of public health efforts is hampered by pervasive stigma.
OBJECTIVE
To perform a systematic literature review to assess the effectiveness of interventions aimed at reducing TB stigma in patients, health care workers, care givers and the general community.
DESIGN
Studies were eligible for inclusion if they evaluated interventions aimed at reducing TB stigma and were published between 1950 and 2015. We searched eight databases (PubMed, Cochrane Library, Ovid, Embase, PsycInfo, Sociological Abstracts, Cumulative Index to Nursing and Allied Health Literature, World Health Organization Latin American and Caribbean Health Sciences Literature), and complemented the searches by using the snowball strategy and by reviewing relevant grey literature.
RESULTS
Only seven studies were identified as providing quantitative (n = 4) or qualitative (n = 3) evidence of effectiveness in reducing TB stigma. Quality assessment of the studies was poor. Knowledge-shaping and attitude-changing interventions aimed at the public, patients and their families were effective in reducing anticipated stigma. Home visits and support groups were effective in reducing both anticipated and internalised stigma.
CONCLUSION
There is a dearth of reliable information on the effectiveness of TB stigma-reduction interventions. Knowledge-shaping, attitude-changing and patient-support interventions can be effective in reducing TB stigma, but more rigorous evaluations are needed.
