Suicide among foreign residents of Japan

The suicide rate of Koreans living in Japan is twice as high as that of Koreans in South Korea. Reasons for this high suicide rate are discussed, including effects of economic crises and discrimination.     

Suicide in Japan: socioeconomic effects on its secular and seasonal trends

Changes in male and female suicide death rates for 33 years following the end of World War II in Japan were analyzed. The death rates for men and women decreased during periods of economic prosperity and then increased during the years preceding economic depression; that for men also increased after economic depression. When examined by profile analysis, the seasonal variation was slightly but significantly different in the four time periods (1950-1955, 1955-1967, 1967-1974, and 1974-1982) in both sexes except between the last two periods (p less than .05). We suggest that death by suicide and its seasonal variation in Japan were affected by changes in socioeconomic conditions.     

Gender and Suicide Risk Among Artists: A Multivariate Analysis

Research on mental disorders among male artists has suggested that artists are at risk of suicide. However, given that men are higher in suicide risk than women, the presumed suicide risk of artists may be an artifact of sampling bias. A logistic regression analysis of data from 21 states finds that artists have a 270% higher risk of suicide than nonartists. However, after controlling for gender and sociodemographic variables, this risk level is reduced to 125%. The findings are related to both psychiatric and work-related stress factors that may place artists at risk of suicide as an occupational group.     

The Effect of Immigration on Suicide: A Cross-National Analysis

Research on the effects of immigration on the rate of suicide has been largely restricted to a few unsystematic case studies of individual cities and nations. This paper performs a systematic cross-national investigation of the impact of the lowered integration and culture shock associated with international migration on the suicide rate in 34 nations. A multiple regression analysis indicates that the rate of immigration affects the incidence of suicide independent of our two control variables, the proportion of the population over 65, and female participation in the labor force, an indicator drawn from the status integration approach to suicide. A 1% increase in immigration is associated with a .13% increase in the rate of suicide. However, analysis of the relative importance of variables in explaining the variance in suicide indicates that our control variables are somewhat more important than the rate of long-term immigration.

Gender,Marriage, and Suicide Acceptability: A Comparative Analysis

The previous work on suicide acceptability hasneglected gender specific analysis of the marriagesuicide acceptability linkage as well as cross-nationalanalysis. The present study fills these gaps in the literature through an analysis of 15nations. Controlling for alternative predictors ofsuicide acceptability, marriage lowers suicideacceptability for both males and females. Further,marriage lowers suicide acceptability more for men than forwomen. This gendered relationship has the same strengthin nations both high and low in economic genderequality. The results provide the first comparativeevidence on the subject. The findings support the notionthat men derive relatively more benefits from marriagethan women. However, the strongest correlates of suicideacceptability (e.g., religiosity, liberalism, French residence) affect men and womenequally.     

Homicide Followed by Suicide: A Comparison with Homicide and Suicide

Homicide‐suicides are a rare yet very serious form of lethal violence which mainly occurs in partnerships and families. The extent to which homicide‐suicide can be understood as being primarily a homicide or a suicide event, or rather a category of its own is examined. In total, 103 homicide‐suicides were compared to 3,203 homicides and 17,751 suicides. These are all events that took place in the Netherlands in the period 1992 to 2006. Logistic regression analyses show that homicide‐suicides significantly differ from both homicides and suicides with regard to sociodemographic and event characteristics. The findings suggest that homicide‐suicide might be considered as a distinct phenomenon from both homicide and suicide.     

Error Types in Ideomotor Apraxia: A Qualitative Analysis

Seventeen brain-damaged subjects with dominant hemisphere pathology and 24 matched control subjects were asked to perform simple familiar gestures under four conditions: (1) verbal command (pantomime), (2) imitation, (3) with the actual object, and (4) verbal command a second time. The subjects subsequently watched a video of an actor performing simple movements and decided whether or not these were performed accurately. The gestural production task was videoed and analyzed for error type. Error type remained consistent over the four task conditions, although subgroups of patients made different types of errors. One group of patients with Ideomotor Apraxia (IMA) made more errors but of the same type as the controls, i.e., movement-related errors and the use of "body part as object" (BPO). The second group made mainly substituted (i.e. unrelated) movements and perseverative errors. The second group of subjects was also poorer at discriminating incorrectly performed movements in the recognition task. BPO errors were commonly made by the control group and they were also chosen as correct in the recognition task. This indicated that use of BPO may reflect a convention in symbolising gestures rather than pathology. The performance of the IMA subjects was discussed in relation to current theories of the mechanisms underlying apraxia.     

Suicide and occupation: A review

This paper examines the available literature dealing with the relation of occupation to suicide for three occupational categories: health care providers, managerial and professional persons, and military and paramilitary personnel. Following a general introduction, evidence relating to group differences in suicidal behavior is presented and assessed. Sources of bias and inaccuracy in suicide statistics are identified and theories purporting to explain variations in the incidence of suicide are considered. Finally, implications are drawn from the analysis presented and possible directions for future research are identified.     

Suicide Risk Assessment and Risk Formulation Part I: A Focus on Suicide Ideation in Assessing Suicide Risk

The main procedure used by clinicians to determine whether an individual may be at risk of suicidal behaviors is the suicide risk assessment (SRA). The purpose of the SRA is to identify risk and protective factors that then provide the data for the formulation of suicide risk. The suicide risk formulation (SRF) assigns a level of suicide risk that ideally leads to triage and treatment deemed appropriate for that level of risk. Some of the problems with the SRA are explored here, with an emphasis on addressing the over reliance on communicated suicide ideation, and recommendations are made for improvements. Part II of this article (Berman & Silverman, 2013, also appears in this issue of STLB) examines the process of an SRF and, similarly, makes recommendations to improve clinical practice toward the desired end of saving lives.     

Treating the Capability for Suicide: A Vital and Understudied Frontier in Suicide Prevention

Current efforts at suicide prevention center largely on reducing suicidal desire among individuals hospitalized for suicidality or being treated for related psychopathology. Such efforts have yielded evidence‐based treatments, and yet the national suicide rate has continued to climb. We propose that this disconnect is heavily influenced by an unmet need to consider population‐level interventions aimed at reducing the capability for suicide. Drawing on lessons learned from other public health phenomena that have seen drastic declines in frequency in recent decades (HIV, lung cancer, motor vehicle accidents), we propose that current suicidality treatment efforts trail current suicidality theories in their lack of focus on the extent to which individuals thinking about suicide are capable of transitioning from ideation to attempt. We summarize extant evidence for specific capability‐centered approaches (e.g., means safety) and propose other options for improving our ability to address this largely overlooked variable. We also note that population‐level approaches in this regard would represent an important opportunity to decrease risk in individuals who either lack access to evidence‐based care or underreport suicidal ideation, as a reduced capability for suicide would theoretically diminish the potency of suicidal desire and, in this sense, lower the odds of a transition from ideation to attempt.     

Time-Series Analysis of Dogmatism Norms Among College Students

Research has shown that values of student activists in the late 1960s differed considerably from student values in the 1950s, and that activists were noticeably low in either dogmatism or authoritarianism. The hypothesis that dogmatism among students in general in the late 1960s was lower than among students in the 1950s was tested by a time-series analysis of secondary data. Dogmatism norms available for the period 1958–1968 showed a significant negative trend over time, and this trend persisted when norms were controlled for education level, geographic region, and college selectivity.     

Suicide: A Multidimensional Malaise

No one really knows why human beings commit suicide. The goal of this paper is to provide a psychological point of view on the topic, among the many other perspectives that are needed. It addresses the question by providing a theory of suicide, arguing that it is theory that allows us to sort out the booming buzzing mess of experience (Wm. James). Suicide is a multidimensional malaise. Metaphorically speaking, it is an intrapsychic drama on an interpersonal stage. As sound theory must be empirically observable, the theory is next applied to research of suicide notes, studying such factors as age, sex, and method of suicide, cross-culture and cross-time. Next, because all theory must have clinical applicability, a clinical case study of Goethe's Werther is provided. Overall, it is concluded that we need to continue to develop models to understand the suicidal mind.     

Youth Suicide Prevention: A Survey and Analysis of Policies and Efforts in the 50 States

State-level initiatives directed at youth suicide prevention since 1980 were analyzed. During 1992 and 1996, each governor was surveyed regarding his or her state's efforts in youth suicide prevention. Questions pertained to legislation, a mandated or recommended school-based suicide prevention curriculum, funding, a special advisory council, a state plan, the development and dissemination of materials, and assessment. Several states sent examples of their prevention activities, which were reviewed to determine the extent to which they represent conceptually and/or empirically grounded preventive intervention strategies. The number of suicides, suicide rates, and percentage change in rate for youth 15–19 years old were reported by state for the periods 1979–1981 and 1992–1994. The results of a repeated measures 2 × 5 ANOVA revealed that while changes in suicide rates over time were statistically significant, there was no relation between these changes and any of the variables studied. Suggestions for future research on state-level initiatives are presented.     

Cognition and Suicide: A Methodological Review

This article reviews the literature related to studies measuring various cognitive properties in suicidal patients. It provides a structural framework with which to classify the studies, and employs the categories of suicidal logic, cognitive style, social cognition, and cognitive control. The methodological issues discussed include: sample characteristics, operational definitions of suicidal behaviors, use of appropriate control groups, and the temporal nature of assessment. Improvements in experimental design are suggested for use in future research.     

A Time-Series Diary Study of Mood and Social Interaction

Based on concomitant time-series analyses, the results of this study support distinct social interaction correlates for the mood dimensions of negative affect (NA) and positive affect (PA). Participants (N = 25) completed structured diaries three times daily for 4 weeks assessing their PA, NA, and participation in five types of social interaction. A significant number of participants' data series evidenced significant positive correlations between PA and fun/active and necessary/informational types of social interaction, and between NA and arguing/confronting and receiving help/support, during synchronous diary periods. Providing help/support was not related to NA or PA. No hypothesized time-lagged relations between mood and social interaction variables were present suggesting that, if these associations exist, they may be at intervals shorter than the one third day recording frequency used in this study. Results are discussed in the context of research on mood, social interaction, and time-series analysis.     

A Psychobiographical Analysis of Faith, Hope, and Despair in Suicide

This paper presents a psychobiographical analysis of a young woman who committed suicide over 50 years ago. Among the documents analyzed are her letters, a high-school diary, creative writing, college newspaper book reviews, and academic papers. Using both an Eriksonian and object-relational theoretical framework, the roles of faith, hope, and despair in suicide—and the ways in which these were represented in the young woman's self-system—are analyzed. Although she possessed strong elements of both faith and hope, along with a will to implement them in a purposeful manner, she was prone to the defense mechanisms of splitting, devaluation, and dissociation, which led to an inability to create an abiding sense of self that may have prevented her descent to despair. Among other issues discussed in the article are the usefulness of psychobiography as a method of studying suicide and both the benefits and limitations of spiritual faith in countering depression and suicide.     

Suicide Attempts and Suicide among Marines: A Decade of Follow‐up

Suicidal behavior among military personnel is of paramount public health importance because of the increased risk of death from suicide in this population. Pre‐ and post‐Marine recruit training risk factors for suicide attempts among current and former Marines were examined in 10 years following recruit training. The characteristics of the subsample of current and former Marines who died by suicide during this time are also described. Stressful and traumatic life events (e.g., childhood physical, sexual, and emotional abuse, sexual harassment during recruit training) and pre‐recruit training suicide attempts emerged as having strong associations with post‐recruit training attempts. Half of those who died by suicide in the 10 years following recruit training endorsed at least one significant life stressor prior to joining the Marines. This study highlights the importance of screening for stressful and potentially traumatic experiences occurring both before and during military service as part of a comprehensive suicide risk assessment in military samples.     

Gender and Suicide in India: A Multiperspective Approach

The gap between male and female suicide rates in India is relatively small. However, society's views on female and male motives are quite different. In order to investigate the perceptions of male and female suicide, we interviewed a focus group of university professors as well as police inspectors, crime reporters, and hospital nurses in Bangalore. We also obtained four narratives of suicide. Women tended to be blamed for their own or their husband's suicide, although they were also viewed more often as victims of life adversities than men. A historical review illustrates that both men and women have been associated with culturally sanctioned suicides. One known form is sati, and we discuss the recent case of sari-murder of Roop Kanwar in 1987. The social sciences and the media also pay a lot of attention to the typical female suicides, symbolizing their role as martyrs of society, which seems to compensate for attribution of blame.
