RESUMO
AIM: This umbrella review aims to determine which interventions can be considered as effective in the prevention and treatment of suicidal behaviour. DESIGN: Umbrella review. METHODS: A systematic search was conducted of works indexed in the PubMed, CINAHL, Cochrane Database of Systematic Reviews, Scopus, ISI Web of Knowledge and Joanna Institute Briggs databases. The search covered works published from 2011 to 2020. RESULTS: The scientific literature shows that, in addition to being the most prevalent interventions in use, dialectical and cognitive behavioural therapies are the most effective in the treatment and management of suicide attempts and suicidal ideation. It is shown that the prevention and treatment of suicidal behaviour requires multidisciplinary and comprehensive management. Among the interventions that stand out the most are the promotion of providing coping tools, work based on thought and behaviour, and behavioural, psychoanalytic and psychodynamic therapies for the management of emotions.
