Sex difference trends in completed suicide

The recent suicide literature increasingly has contained statements suggesting that the differences in completed suicide between the sexes are lessening. A compilation of official suicide data for 1933-1980 verifies such a trend from the 1950s through 1971. However, increased differences (as measured by the ratio of male to female rates) were consistently observed from 1971 to 1980. These trends were found for data for the nation, for whites and nonwhites, for numbers of suicides, for crude rates, and for age-adjusted rates. Decreased sex differences were obtained for those 35-44, 45-54, 55-64, and for 65+ years of age, but increased sex differences were observed for those aged 15-24 and 25-34. Possible explanations for these findings are presented.     

Sex differences in peer responsiveness to suicide ideation

Two surveys assessing attitudes toward and beliefs about suicide were conducted with undergraduates. There were 473 participants in Survey I and 692 participants in Survey II. Sex differences were found in participants' receptivity to suicidal individuals, beliefs about the behavior of suicidal peers, attitudes concerning the worth of suicidal people, incidence of adolescent suicide, and morality of suicide. There was no sex difference in participants' own frequency or seriousness of suicide ideation or suicide attempts. Results are discussed in terms of hypotheses concerning traditional socialization of males and females, resulting in sex-role differentiation that may influence attitudes toward and beliefs about suicide.     

Sex differences in completed suicide by schizophrenic patients: a meta-analysis

A meta-analysis was conducted on all studies of suicide mortality in follow-up studies of schizophrenic patients that presented data for male and female patients separately. The percentage of deaths from suicide was significantly greater for the male schizophrenic patients than for the female schizophrenic patients in studies where both sexes were included. Regression equations devised to predict the percentage of deaths from suicide after all of the sample had died estimated that 0.50% of male schizophrenic patients would die from suicide as compared to 0.20% of female schizophrenic patients. Suggestions are made for future research.     

Inpatient suicide in a Chinese psychiatric hospital

Little is known about the risk factors for suicide among psychiatric inpatients in China. In this study we identified the risk factors of suicide among psychiatric inpatients at Guangzhou Psychiatric Hospital. All psychiatric inpatients who died by suicide during the 1956-2005 period were included in this study. Using a case-control design, 64 inpatients with schizophrenia who died by suicide were compared with a matched 64 controls. The results indicate that the rate of suicide was 133.1/100,000 admissions (95%CI 103.4-162.9). There were no significant differences in the method, location, or time of suicide between male and female inpatients. The number of hospitalizations was significantly larger in the suicide group than that in the control group. In logistic regression analyses, guilty thought, depressive mood, and suicidal ideation and suicide attempt 1 month before hospital admission were identified as independent predictors of suicide among inpatients with schizophrenia. The findings of risk factors for schizophrenic inpatient suicide should be taken into account when developing interventions to prevent suicide among these patients.     

National income, life satisfaction, and male-female suicide ratio in industrialised countries

The relationships between gross domestic product (GDP) per capita, life satisfaction, and male-female suicide ratio were analyzed for 25 industrialized countries. GDP per capita was the strongest correlate of male-female suicide ratio even when life satisfaction was controlled using partial correlations. Life satisfaction correlated significantly with GDP per capita but not with suicide rates.     

Attitudes toward suicide among Chinese people in Hong Kong

Since suicide in Chinese people exhibits certain distinctive characteristics, it is important to develop indigenous measures to assess Chinese attitudes toward suicide that may be used to inform suicide reduction programs. Combining qualitative and quantitative methods, we developed a Hong Kong version of the Chinese Attitude toward Suicide Questionnaire (CASQ-HK) which assesses attitudes toward suicide, suicidal inclination under 12 hypothetical scenarios, and prior suicidal experience. A convenience sample of 1,226 people completed the self-report questionnaire. In keeping with Chinese tradition, respondents revealed both tolerant and condemning attitudes that varied with their sociodemographic characteristics. Generally, they were not strongly inclined to consider suicide in the presence of difficult scenarios. Female gender, older age, and the presence of suicidal ideation were associated with more contemplation of suicide.     

More Than a Sex Machine: Accomplishing Masculinity Among Chinese Male Sex Workers in the Hong Kong Sex Industry

Situated in the masculinity and deviance literature, this article examines a “deviant” masculinity, that of the male sex worker, and presents the ways men who engage in sex work cope with the job. Based on in-depth interviews of Chinese male sex workers (n = 18) in the Hong Kong sex industry, I argue that the stigma management techniques these men employ are simultaneously gender strategies they use to accomplish masculinity. It is through this process that they negotiate a masculine identity within the hierarchy of masculinities in order to become “respectable” and “responsible” Chinese men.     

Sex differences in the psychological well-being of Chinese adolescents

This study assessed sex differences affecting the psychological well-being of Chinese adolescents. Various instruments were used to measure psychiatric symptoms and positive mental health. The results showed that female adolescents displayed significantly more psychiatric as well as somatic symptoms and scored lower on scales reflecting positive mental health. The findings are generally consistent with those found in the Western literature, but suggest that, in the Chinese culture, sex differences in mental health begin to appear in adolescents.

Sex differences in developmental trends of suicide ideation, plans, and attempts among European American adolescents

Although suicide ideation, plans, and attempts increase during adolescence, it remains unclear whether boys' and girls' risk for these outcomes peaks at different ages. We used longitudinal categorical data (never, once, 2+ times) from the Family Transitions Project (N = 1,248 rural European Americans, ages 11-19) to investigate whether yearly prevalence rates of adolescent suicidal episodes follow different patterns by sex. Multiple-group growth models revealed that peak levels of past-year ideation and plans occurred during mid adolescence for girls, but slowly increased through late adolescence for boys. We found that prevalence patterns for attempts were very similar for boys and girls, with both increasing through mid adolescence and then declining, although girls' risk declined slightly more rapidly. This information may help alert gatekeepers to developmental periods during which boys and girls are particularly vulnerable to suicide-related experiences, and also may help inform the timing of preventive efforts.     

Sex ratio and mate preferences: a cross‐cultural investigation

Sex ratio is the number of men per 100 reproductive‐age women within a specified mating pool. We generated and tested two hypotheses about the cross‐cultural relationships between sex ratio and mate preferences using preference ratings of 18 characteristics provided by 9809 participants and corresponding sex ratio data secured from an international organization. The Classical Sex Ratio Mate Preference Shifts Hypothesis predicts that in imbalanced sex ratio societies, the more numerous sex will lower their standards, to facilitate acquisition of a partner of the less numerous sex. The Alternative Sex Ratio Mate Preference Shifts Hypothesis predicts that in lower sex ratio societies, men will lower their standards to secure more short‐term matings, whereas women will raise their standards to avoid deception by men seeking short‐term relationships. Results supported the Classical Sex Ratio Mate Preference Shifts Hypothesis for men, and the Alternative Sex Ratio Mate Preference Shifts Hypothesis for women. Discussion addresses limitations of the current research and highlights future directions for research on the relationships between sex ratio and mating psychology and behavior.

Grandiose narcissism,depression and suicide ideation in Chinese and German students

Current Psychology - In Western cultural context, grandiose (overt) narcissism has been shown to be either unrelated or negatively related to negative mental health (depression, suicide ideation)....     

Depression, suicide, and suicide prevention in schizophrenia

Suicide is the single largest cause of premature death among individuals with schizophrenia. Furthermore, epidemiological data indicate that nearly 80% of patients with the diagnosis of schizophrenia will experience a major depressive episode at some time during their lifetime. This report reviews recent findings relative to the risk of suicide in schizophrenia, including data from the Chestnut Lodge longitudinal study of schizophrenia subtypes and symptom domains. Paradoxically, those patients with schizophrenia who are most likely to recover or experience a good outcome are also those at greatest risk for suicide. The reduction of morbidity and mortality in schizophrenia should include depression and suicidality as targets for both psychopharmacological and psychosocial treatment.     

Measuring Gender Orientation with the Bem Sex Role Inventory in Chinese Culture

To test the validity of the Bem Sex Role Inventory (BSRI) and its application in Chinese culture, the instrument was administered to 302 American (101 males and 201 females) and 273 Chinese (120 males and 153 females) college students. Factor analyses and analysis by gender yielded different patterns across cultures. Subsequent results yielded a short form of eight male-oriented items and eight female-oriented items that were equivalent across cultures. The short form constructed in this study is expected to apply to future cross-cultural research on gender orientation. The study supports previous findings that masculine and feminine do not load on the major factors, and therefore it is misleading to name the two shortened scales as such. Further, a comparison of the BSRI scores across samples revealed that Chinese scores are generally lower than those of Americans, and explanations are made in light of Chinese culture.     

Sex differences in cognitive abilities and sex-role stereotypes in Hong Kong Chinese adolescents

A study was conducted to test the hypothesis that sex differences in patterns of cognitive ability could be accounted for by variation in identification with sex-role stereotypes. Hong Kong Chinese adolescents from two different age groups served as subjects. Sex differences were discovered in patterns of performance on a battery of cognitive tests, with males performing better on tests of spatial ability and females performing better on tests of fluent production. Sex differences in sex-role identification were also discovered. There were, however, no significant relationships between sex-role identification and patterns of ability. Biological sex was found to be the best predictor of a male or female pattern of performance. A reformulation of a sex-role identification hypothesis appears to be warranted on the basis of these data. Suggestions for further research on the relationships among sex-role identification, cultural values, and personal adjustment are also presented.This report is based on a doctoral dissertation submitted to the faculty of Harvard University. The research was supported by a National Research Service Award, National Institutes of Health Grant 5-T32-MH14088, awarded to Beatrice Whiting and John Whiting to support graduate research in cross-cultural child development.     

Motives for suicide in suicide notes from women and men

Suicide notes written by 16 adult women and 16 men were evaluated by 16 nonprofessional adult judges with regard to love or work problems as suicide motives. Consistent with current theory on gender and suicidal behavior, women and men did not differ in love or work motives.     

Contribution of imitative suicide to the suicide rate in prisons

Suicide rates in prisons are high. Our aim was to investigate the contribution of imitative suicide to the prison suicide rate. We used Knox tests for space-time clustering in a case register of natural and self-inflicted deaths in prisons in England and Wales and model simulations to estimate the effect size. We found significant space-time clustering among 657 self-inflicted deaths in 90 prisons over 10 years but no space-time clustering among 430 deaths from natural causes in 87 prisons over this period. Model simulations with an imitation rate of 5.8% (CI 1%-11%) reproduced the observed space-time clustering.
