Suicidal behaviour is defined as taking actions with the intention of killing oneself and thinking of performing these actions. Suicide is a serious public health problem with complex biological, social and psychological risk factors and a multidimensional clinical appearance, occurring all over the world and ranking among the leading causes of death. In this study, psychological approaches explaining suicide were evaluated under the headings of first-generation and second-generation suicide theories, the different aspects of these theories were put forward, and previously published studies and recent evidence were reviewed. A literature review on the theoretical foundations of suicide is presented. First-generation suicide theories were developed before the 2000s and second-generation suicide theories were developed after the 2000s. While Psychodynamic Theory, Social Learning Theory, Hopelessness Theory, Shneidman's Suicide Theory and Escape Theory are included under the title of first-generation suicide theories, Interpersonal Psychological Suicide Theory, Three Stage Suicide Theory, Complementary Motivational-Demotivational Theory and Variable Predisposition Theory are examined as second-generation suicide theories. The approaches of the theories provide important evidence in understanding suicidal behaviour and recognising various risk factors in the transition from suicidal ideation to suicidal action. Controlling the risk factors may contribute both in terms of preventive community mental health and in the development of health policies.
