Objective Accurate information about preferred suicide methods is important for devising strategies and programmes for suicide prevention. Our knowledge of the methods used and their variation across countries and world regions is still limited. The aim of this study was to provide the first comprehensive overview of international patterns of suicide methods. Methods Data encoded according to the International Classification of Diseases (10th revision) were derived from the WHO mortality database. The classification was used to differentiate suicide methods. Correspondence analysis was used to identify typical patterns of suicide methods in different countries by providing a summary of cross-tabulated data. Findings Poisoning by pesticide was common in many Asian countries and in Latin America; poisoning by drugs was common in both Nordic countries and the United Kingdom. Hanging was the preferred method of suicide in eastern Europe, as was firearm suicide in the United States and jumping from a high place in cities and urban societies such as Hong Kong Special Administrative Region, China. Correspondence analysis demonstrated a polarization between pesticide suicide and firearm suicide at the expense of traditional methods, such as hanging and jumping from a high place, which lay in between. Conclusion This analysis showed that pesticide suicide and firearm suicide replaced traditional methods in many countries. The observed suicide pattern depended upon the availability of the methods used, in particular the availability of technical means. The present evidence indicates that restricting access to the means of suicide is more urgent and more technically feasible than ever.

We examined the change in Swiss suicide rates since 1969, breaking down the rates according to the method used. The descriptive analyses of the main suicide methods are presented. The suicide rates reached a peak in the late 1970s/early 1980s and declined in more recent years. Firearm suicides and suicides by falls were the exception and sustained their upwards trend until the 1990s. Suicide by vehicle exhaust asphyxiation showed a rapid decline following the introduction of catalytic converters in motor vehicles. No substantial method substitution was observed. Suicide by poisoning declined in the 1990s but rose again following an increase in assisted suicide in somatically incurable patients. Suicide is too often regarded as a homogeneous phenomenon. With regard to the method they choose, suicide victims are a heterogeneous population and it is evident that different suicide methods are chosen by different people. A better understanding of the varying patterns of change over time in the different suicide methods used may lead to differentiated preventive strategies.

Background. To examine the effect of time on suicide after bereavement among widowed persons.Method. The data were extracted from Swiss mortality statistics for the period [1987][1988][1989][1990][1991][1992][1993][1994][1995][1996][1997][1998][1999][2000][2001][2002][2003][2004][2005]. The time between bereavement and subsequent death, specifically by suicide, was determined by linkage of individual records of married persons. The suicide rates and the standardized mortality ratios in the first week/month/year of widowhood were calculated based on person-year calculations.Results. The annualized suicide rates in widowed persons were highest in the first week after bereavement : 941 males and 207 females per 100 000. The corresponding standardized mortality ratios were approximately 34 and 19 respectively. In the first month(s) after bereavement, the rates and the ratios decreased, first rapidly, then gradually. Except in older widows, they did not reach the baseline levels during the first year after bereavement.Conclusions. The suicide risk of widowed persons is increased in the days, weeks and months after bereavement. Widowed persons are a clear-cut risk group under the aegis of undertakers, priests and general practitioners.

Abstract. Background: The therapeutic alliance may be a moderating factor of outcome in the Attempted Suicide Short Intervention Program (ASSIP). Aims: This study investigates the two components of the therapeutic alliance, patients' satisfaction with the therapeutic relationship and therapeutic outcome and their associations with suicidal ideation over time. Method: A total of 120 patients (55% female; mean age = 36 years) with a history of attempted suicide were randomly allocated to either the intervention group ( N = 60) or the control group ( N = 60). Patients' satisfaction with the therapeutic relationship and outcome were measured with the two subscales of the Helping Alliance Questionnaire. The Beck Scale of Suicide Ideation was used to measure suicidal ideation in this 24-month follow-up study. Results: The ASSIP group showed that patients' satisfaction with therapeutic relationship and outcome increased significantly from the first to the third session. Higher satisfaction with therapeutic outcome correlated significantly with lower suicidal ideation at follow-up. Conversely, the control group showed no significant results. Limitations: The collaborative approach adopted in the initial clinical interview of the control group could possibly have influenced the results of both scales. Conclusion: In particular, the component satisfaction with therapeutic outcome seems crucial to the subjectively perceived satisfaction of treatment and is associated with lower suicidal ideation over time. Thus, an enhanced understanding of components of the therapeutic alliance plays an important role in the development of interventions for suicidal patients.
