Abstract
Recent developments in the understanding, assessment and treatment of suicidal behaviour are reviewed. The accumulated social and demographic knowledge of suicidal populations has proved to be clinically useful in shaping the general level of concern, but at the individual level an understanding of the psychological processes involved in suicidal behaviour is required. Studies examining psychological processes involved in suicidal behaviour is required. Studies examining psychological processes in parasuicidal groups have revealed a number of deficits, including poor interpersonal problem solving, hopelessness about the future, and reduced ability to regulate affect. Research has also begun to look at some of the processes underlying these deficits, such as over-general retrieval of autobiographical memories and reduced anticipation of specific positive experiences. The clinical picture is now more optimistic, with therapies, such as Dialectical Behaviour Therapy, which focus on using problem solving strategies with those clients who are most vulnerable to repeat parasuicide episodes, producing demonstrable delays in parasuicide and reduced risk of repetition. The importance of the relationship between research and clinical practice is emphasized.
