Suicide data from Sweden (1911-1993) and New Zealand (1975-1995) were used to test a hypothesis derived as an extension of the Seasonal Affective Disorder concept. Contrary to the hypothesis, but similar to what Durkheim had reported regarding Central Europe in the nineteenth century, suicides peaked in late spring (May in Sweden, November in New Zealand). Durkheim's hypothesis that there would be more monthly variation in suicides in rural areas was strongly supported. Our hypothesis is that people abandon life when it is least difficult because of a disjuncture between experience and expectation.

All available data for thirteen Pacific Island nations are used in a comparative analysis of suicide levels and characteristics. Age, sex and method of suicide are examined in detail. Global comparison shows Pacific rates are amongst the highest reported. Female youth rates exceed male rates in Western Samoa and amongst Fiji Indians. Method of suicide (paraquat ingestion) is instrumental in determining high rates in Western Samoa, especially in females. The broad causal theme is societal transition. Commonality and diversity are discussed.

Injury deaths can be grouped into four general categories: accident, homicide, suicide, and undetermined The present study investigates the use of the ''undetermined'' category. External cause of death, as well as demographic and other variables, were abstracted from death certificates of the 386,936 Californians who died of an injury between 1969 and 1991. Differences among the four manner-of-death groups were examined and characteristics of the decedent and the injury event were used to predict a classification of undetermined Coroners classified 1.9% of the deaths as undetermined in manner Deaths of women, Blacks, Asians and Native Americans;the very young and the middle aged;or those involving poisoning or submersion were most likely to be classified as undetermined Acknowledging that individual coroner judgment may not be free of bias, these findings can help provide a better estimate of the frequency and the epidemiologic features of injury deaths that are assigned to the category of undetermined.

Few cross-national reports have examined suicide rates among adolescents and young adults. A survey of suicides among 15-24-year-olds in 34 of the wealthiest nations demonstrated that 15,555 youths killed themselves in a 1-year study period. Thirty-four percent of these suicides were firearm-related. Finland led the participating nations in total and firearm-related suicide rates. An association was found between divorce rates and youth suicide rates, firearm-related suicide among youths, and suicide rates among young males. For a smaller sample of countries, an association was found between firearm availability and firearm-related suicide rates among youths and suicide rates among young males.

This prospective study examined the utility of several cognitive variables as predictors of suicide risk among 79 hospitalized psychiatric patients. These variables included pessimism (measured by the Hopelessness Scale), perceived and actual problem-solving ability (indexed by the Problem-Solving Inventory and Means-End Problem-Solving test, respectively), and polarized thinking, self-negativity, and construct system constriction and differentiation (derived from a repertory grid). Suicide risk was operationalized in terms of subsequent self-report of suicide ideation and staff records of time spent on suicide precautions. Results indicated that hopelessness, self-negativity, and poor problem-solving performance functioned as reliable predictors of suicide risk, whereas self-evaluated problem-solving ability did not. Interestingly, constriction emerged as a significant inverse predictor across criterion measures, suggesting that it might better be conceived as a measure of subjective uncertainty. Finally, patients at highest risk for actual suicidal behaviors could be discriminated on the basis of a unique cognitive structure marked by high degrees of differentiation and polarization, suggesting that conceptual disorganization and all-or-nothing thinking may provide an instigating context for suicidal or parasuicidal behavior.

Objective: To study trends in the rate of suicide in psychiatric patients in Western Australia. To examine the associations of suicide with demographic and clinical factors. Methods: A population-based cohort of 52,010 individuals whose first psychiatric admission occurred in 1980-95 was identified from the Health Services Research Linked Database. There were 471 deaths by suicide by 31 December 1995. Age standardised suicide rates per 1,000 person-years at risk were calculated. Suicide rates in the first year after a patients first admission were also examined and a proportional hazards regression analysis was performed to examine risk factors for suicide. Results: Male psychiatric patients were 3.4 times more likely to commit suicide than female patients (95% CI 2.76-4.24). Younger patients were at higher risk than older patients, and patients with extended periods of in-patient treatment were at more than double the risk of short-stay patients. Over the 16-year period, the rate of suicide in the first year after first psychiatric admission was found to increase by 3.4% a year (95% CI -0.7-7.6%). Conclusions: The findings confirm that psychiatric patients are at high risk of suicide. Patient outcomes in terms of risk of suicide after hospital discharge have deteriorated. Implications: Improvements are needed in the provision of community support to high risk psychiatric patients. Further work should be done to identify patients at highest risk of suicide.
