Suicidal behavior is a significant medical, public health and mental health problem in New Zealand, just as it is in many countries. Those who have made suicide attempts are at high risk of making further nonfatal suicide attempts and of suicide. This chapter presents reports of a longitudinal study of 302 individuals who had made medically serious suicide attempts and who were then followed-up for a period of 30 months subsequent to these attempts. It documents the history of this cohort in the following areas of functioning: rates of mortality, suicide and nonfatal suicide attempt; history of psychiatric morbidity; and rates of a series of selected measures of psychosocial functioning including relationship problems, social welfare benefit receipt, criminality and imprisonment. The outcome following serious suicide attempts is often considerably bleak, and is characterized by long-term and severe psychosocial problems and by lives which begin to reflect deprivation of care.
