This chapter considers non-legislative pressures in mental health community treatment, reviews the current body of evidence, and offers recommendations for future research. It attempts to clarify terminology on treatment pressures including different forms of ‘leverage’ such as housing, financial, criminal justice, childcare leverages, and perceived coercion. Based on a scoping review the chapter portrays current international evidence on prevalence, predictors, and outcomes of informal coercion (for example persuasion, interpersonal leverage, inducement, threats, and force) in both quantitative and qualitative studies with patients, with attention to the issues of the perception of fairness and the effectiveness of treatment, financial incentives to improve adherence, and sources of informal coercion. It also discusses common limitations and recommendations for future research.
