Parasuicide in Europe: the WHO/EURO multicentre study on parasuicide. I. Introduction and preliminary analysis for 1989

The WHO/EURO multicentre study on parasuicide is a new, coordinated, multinational, European study that covers two broad areas of research: monitoring trends in the epidemiology of parasuicide (epidemiological monitoring study); and follow‐up investigations of parasuicide populations, with a view to identifying the social and personal characteristics predictive of future suicidal behaviour (repetition prediction project). This article provides background information on the development and organization of the multicentre study, and presents selected findings from the epidemiological monitoring project, based on a preliminary examination of data collected in 15 centres on parasuicides aged 15 years and over treated in health facilities in defined catchment areas during the year 1989. The overall parasuicide incidence varied considerably across the centres, from a high (event) rate of 414 per 100,000 males in Helsinki to a low of 61 among males in Leiden. The highest female event rate was 595 in Pontoise, and the lowest 95 in Guipuzcoa. The mean event rate across all centres was 167 among males and 222 among females. Parasuicide incidence tended to be elevated among 15‐ to 34‐year‐olds, with lowest rates among those aged 55 years and over. With one exception (Helsinki), the female parasuicide rate was higher than the male rate, the F:M ratio ranging from 0.71:1 to 2.15:1, with a median of 1.5:1 (events). Short‐term repetition rates (as measured by the event:person ratio) differed between centres, from 1.03 to 1.30 (median = 1.12) among males, and from 1.07 to 1.26 (median = 1.13) among females. Although we warn against generalizing from our findings to make statements about differences in parasuicide between countries, we argue that the differences between centres are valid and should be addressed in further research.

The Werther effect after television films: new evidence for an old hypothesis

In this study it was possible to prove the Werther effect in suicides after watching fictional models for the first time. A twice-broadcast (1981, 1982) six-episode weekly serial showing the railway suicide of a 19-year-old male student provided a quasi-experimental ABABA design to investigate differential effects of suicide imitation. Imitation effects were most clearly observable in the groups whose age and sex were closet to those of the model. Over extended periods (up to 70 days after the first episode), the number of railway suicides increased most sharply among 15- to 19-year-old males (up to 175%); the effect steadily decreased in the older age groups, so that no effect was observable for males over 40 years and females over 30 years. Also, the imitation effects remained detectable for longer periods in the groups closest in age to the model. The increases observed after the first and second broadcast for males aged less than 30 years closely corresponded with the respective audience figures for the two showings.

The alliance against depression: 2-year evaluation of a community-based intervention to reduce suicidality

BACKGROUND The global burden and large diagnostic and therapeutic deficits associated with depressive disorders call for intervention programs. The aim of the Nuremberg Alliance against Depression (NAD) is to establish and to assess the effectiveness of a four-level intervention program for improving the care of patients with depression. METHOD A 2-year intervention program was performed in Nuremberg (480000 inhabitants) at four levels: training of family doctors and support through different methods; a public relations campaign informing about depression; cooperation with community facilitators (teachers, priests, local media, etc.); and support for self-help activities as well as for high-risk groups. The effects of the 2-year intervention on the number of suicidal acts (completed suicides plus suicide attempts, main outcome criterion) were evaluated with respect to a 1-year baseline and a control region (Wuerzburg, 270,000 inhabitants). RESULTS Compared to the control region, a reduction in frequency of suicidal acts was observed in Nuremberg during the 2-year intervention (2001 v. 2000: -19.4%; p< or =0.082; 2002 v. 2000: -24%, p< or =0.004). Considering suicide attempts only (secondary outcome criterion), the same effect was found (2001 v. 2000: -18.3%, p< or =0.023; 2002 v. 2000: -26.5%, p<0.001). The reduction was most noticeable for high-risk methods (e.g. hanging, jumping, shooting). Concerning completed suicides, there were no significant differences compared to the control region. CONCLUSIONS The NAD appeared to be effective in reducing suicidality. It provides a concept as well as many methods that are currently being implemented in several other intervention regions in Germany and in other countries.

Relation between attempted suicide and suicide rates among young people in Europe.

STUDY OBJECTIVE: To determine if there are associations between rates of suicide and attempted suicide in 15-24 year olds in different countries in Europe. DESIGN: Attempted suicide rates were based on data collected in centres in Europe between 1989 and 1992 as part of the WHO/EURO Multicentre Study of Parasuicide. Comparison was made with both national suicide rates and local suicide rates for the areas in which the attempted suicide monitoring centres are based. SETTING: 15 centres in 13 European countries. PATIENTS: Young people aged 15-24 years who had taken overdoses or deliberately injured themselves and been identified in health care facilities. MAIN RESULTS: There were positive correlations (Spearman rank order) between rates of attempted suicide and suicide rates in both sexes. The correlations only reached statistical significance for male subjects: regional suicide rates, r = 0.65, p < 0.02; national suicide rates, r = 0.55, p < 0.02. CONCLUSIONS: Rates of attempted suicide and suicide in the young covary. The recent increase in attempted suicide rates in young male subjects in several European countries could herald a further increase in suicide rates.

Optimizing Suicide Prevention Programs and Their Implementation in Europe (OSPI Europe): An evidence-based multi-level approach

BackgroundSuicide and non-fatal suicidal behaviour are significant public health issues in Europe requiring effective preventive interventions. However, the evidence for effective preventive strategies is scarce. The protocol of a European research project to develop an optimized evidence based program for suicide prevention is presented.MethodThe groundwork for this research has been established by a regional community based intervention for suicide prevention that focuses on improving awareness and care for depression performed within the European Alliance Against Depression (EAAD). The EAAD intervention consists of (1) training sessions and practice support for primary care physicians,(2) public relations activities and mass media campaigns, (3) training sessions for community facilitators who serve as gatekeepers for depressed and suicidal persons in the community and treatment and (4) outreach and support for high risk and self-help groups (e.g. helplines). The intervention has been shown to be effective in reducing suicidal behaviour in an earlier study, the Nuremberg Alliance Against Depression. In the context of the current research project described in this paper (OSPI-Europe) the EAAD model is enhanced by other evidence based interventions and implemented simultaneously and in standardised way in four regions in Ireland, Portugal, Hungary and Germany.The enhanced intervention will be evaluated using a prospective controlled design with the primary outcomes being composite suicidal acts (fatal and non-fatal), and with intermediate outcomes being the effect of training programs, changes in public attitudes, guideline-consistent media reporting. In addition an analysis of the economic costs and consequences will be undertaken, while a process evaluation will monitor implementation of the interventions within the different regions with varying organisational and healthcare contexts.DiscussionThis multi-centre research seeks to overcome major challenges of field research in suicide prevention. It pools data from four European regions, considerably increasing the study sample, which will be close to one million. In addition, the study will gather important information concerning the potential to transfer this multilevel program to other health care systems. The results of this research will provide a basis for developing an evidence-based, efficient concept for suicide prevention for EU-member states.

Cluster B personality disorders are associated with allelic variation of monoamine oxidase A activity.

Genetic variants of the monoamine oxidase A (MAOA) have been associated with aggression-, anxiety-, and addiction-related behavior in several nonclinical and clinical populations. Here, we investigated the influence of allelic variation of MAOA activity on aggression-related personality traits and disease risk in patients with personality disorders. Personality disorders were diagnosed with the Structured Clinical Interview of DSM-IV and were allocated to cluster A, B, and C. Personality features were assessed by the revised NEO Personality Inventory and the Tridimensional Personality Questionnaire. The genotype of the MAOA gene-linked polymorphic region (MAOA-LPR) was determined in 566 patients with personality disorders and in 281 healthy controls. MAOA genotype was significantly associated with cluster B personality disorders (χ2=7.77, p=0.005, df=1) but not with cluster C personality disorders. In total, 26.0% of cluster B patients were hemi- or homozygous for the low-activity variant of the MAOA genotype, compared to 16.4% in the control group. Associations between MAOA variants and personality domains related to impulsivity and aggressiveness were inconsistent. Our findings further support the notion that allelic variation of MAOA activity contributes modestly to the balance of hyper- (impulsive-aggressive) and hyporeactive (anxious-depressive) traits.

A repetition–prediction study of European parasuicide populations: a summary of the first report from Part II of the WHO/EURO Multicentre Study on Parasuicide in co‐operation with the EC Concerted Action on Attempted Suicide

One of the aims of the European Study on Parasuicide, which was initiated by the Regional Office for the European Region of the World Health Organization in the mid‐1980s, was to try to identify social and personal characteristics that are predictive of future suicidal behaviour. A follow‐up interview study (the Repetition‐Prediction Study) was designed, and to date 1145 first‐wave interviews have been conducted at nine research centres, representing seven European countries. The present paper provides an abridged version of the first report from the study. The design and the instrument used (The European Parasuicide Study Interview Schedules, EPSIS I and II) are described. Some basic characteristics of the samples from the various centres, such as sex, age, method of suicide attempt, and history of previous attempts, are presented and compared. The male/female sex ratio ranged from 0.41 to 0.85; the mean age range for men was 33–45 years and that for women was 29–45 years. At all of the centres, self‐poisoning was the most frequently employed method. On average, more than 50% of all respondents had attempted suicide at least once previously. The representativeness of the samples is discussed. There were differences between the centres in several respects, and also in some cases the representativeness of the different samples varied. Results obtained from analyses based on pooled data should therefore be treated with caution.

5-HT1A receptor function in depression: effect of chronic amitriptyline treatment

Hypothermic responses to 5-HT1A receptor activation by the selective ligand ipsapirone (IPS) were attenuated in depressed patients as compared to controls. Chronic treatment with amitriptyline (AMI) further impaired 5-HT1Amediated hypothermia. The results indicate a subsensitive (presynaptic) 5-HT1A receptor and/or a defective post-receptor signalling pathway in depression and are consistent with the hypothesis that 5-HT1A receptors are down-regulted during AMI treatment.

Problem solving ability and repetition of deliberate self-harm: a multicentre study.

BACKGROUND While recent studies have found problem-solving impairments in individuals who engage in deliberate self-harm (DSH), few studies have examined repeaters and non-repeaters separately. The aim of the present study was to investigate whether specific types of problem-solving are associated with repeated DSH. METHOD As part of the WHO/EURO Multicentre Study on Suicidal Behaviour, 836 medically treated DSH patients (59% repeaters) from 12 European regions were interviewed using the European Parasuicide Study Interview Schedule (EPSIS II) approximately 1 year after their index episode. The Utrecht Coping List (UCL) assessed habitual responses to problems. RESULTS Factor analysis identified five dimensions--Active Handling, Passive-Avoidance, Problem Sharing, Palliative Reactions and Negative Expression. Passive-Avoidance--characterized by a pre-occupation with problems, feeling unable to do anything, worrying about the past and taking a gloomy view of the situation, a greater likelihood of giving in so as to avoid difficult situations, the tendency to resign oneself to the situation, and to try to avoid problems--was the problem-solving dimension most strongly associated with repetition, although this association was attenuated by self-esteem. CONCLUSIONS The outcomes of the study indicate that treatments for DSH patients with repeated episodes should include problem-solving interventions. The observed passivity and avoidance of problems (coupled with low self-esteem) associated with repetition suggests that intensive therapeutic input and follow-up are required for those with repeated DSH.

Suicidal behaviour on railways in the FRG

Between 1976-84 there were 6090 suicides and 391 attempted suicides on railways in the Federal Republic of Germany. This suicide method was compared to other methods with respect to seasonal and daily distributions and fluctuations by time of day for age and sex. The ratio of males to females was 2.54:1 and the relative incidence of this type of suicide as compared to the total number of suicides was high among the younger age groups. Investigation of seasonal variation revealed a peak for males in the autumn. There was a markedly higher incidence of railway suicides committed by males on Mondays and Tuesdays. This peak was less pronounced for females. Most incidents occurred in the evening hours (especially after sunset). An investigation of the relationship between the severity of injuries and the location of the suicide attempt revealed that those who attempted suicide on railway tracks in the countryside were more seriously injured than those whose attempt took place in or near main stations.
