In recent years, international organizations, professionals, and representatives of mental health service users have expressed the need to regulate, limit, and even eliminate coercive measures in psychiatric treatment. The main objective of the current review is to provide a comprehensive synthesis of existing evidence on coercion in mental health care through a protocol for an umbrella review of systematic reviews. This protocol was designed according to the Joanna Briggs Institute guide for methodological development, conduct, and reporting of umbrella reviews. To minimize bias in the process, two independent reviewers selected the studies to be included, extracted, and synthesized; analyzed the data; and assessed risk of bias of each review. The review protocol was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols guidelines. This review offers a comprehensive compilation of systematic reviews on coercion developed to date. Coercion causes adverse physical and psychological effects and is an emotional stressor for individuals with psychiatric diagnoses and health care workers. Characterization of coercion across care settings, its impact on clinical outcomes, the perception of those involved, and how coercion could be reduced will also be discussed.
