[Effectiveness of anti-stigma interventions regarding severe mental illness: a systematic literature review].

Stigma is one of the greatest challenges facing people with severe mental illness (smi) and can have profound psychological, social and professional consequences.
AIM: To systematically review the evidence of effectiveness of anti-stigma interventions (anti-stigma campaigns and specific interventions to reduce public stigma and self-stigma) for people with smi and to make recommendations for clinical practice.
METHOD: A systematic literature search for individual studies and reviews concerning the efficacy of interventions that reduce stigma for people with smi.
RESULTS: Anti-stigma interventions have small-to-medium effects. Although head-to-head comparisons do not show a clear advantage for educational or contact interventions, results suggest that the elements of contact, recovery and continuity (for public stigma) and psycho-education (for self-stigma) may yield the greatest effects. Due to the short follow-up period of most studies, there is limited evidence on the long-term effectiveness of these interventions. More specifically, it remains unknown whether these interventions lead to changes in actual behavior.
CONCLUSION: Anti-stigma interventions have limited effects on knowledge, attitudes and behavior. Several methodological shortcomings, as well as short follow-up periods in most studies, preclude making firm conclusions.
