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.     

National differences in intelligence and population rates of suicidal ideation, suicide plans, and attempted suicide

Population rates of suicidal ideation, suicide plans or attempted suicide from three independent multinational epidemiological surveys (the WHO/EURO and WHO SUPRE-MISS studies and a third one) were not significantly associated with national IQ figures. This result conflicts with previous evidence from cross-national studies (by Lester and by Voracek) of a positive ecological correlation between level of national intelligence and rates of completed suicide. Across nations, the indicators for the prevalence of suicidal behavior also lacked close correspondence with suicide rates, which may be due to the higher unreliability of assessing covert suicidal behavior (suicide ideas, thoughts, plans, and, to a lesser extent, also suicide attempts) as compared to suicidal behavior that is indisputably overt (completed suicide). Several alternative explanations for the current nil findings are also discussed.     

Sex differences in symptoms of depression among American children and adolescents

The Arabic Children's Depression Inventory in its English version was administered to a sample of 535 U.S. school students (11 to 18 years old). By sex, differences on total score and on 19 of 27 items (70.4%) were not statistically significant. Nevertheless, differences were significant for 8 (29.6%) items on which girls had higher mean scores. Half of the items were positive indicators of depression (I am sad, I feel lonely, I feel miserable, and I hate myself), while the other half were negative (I feel happy, Life is rosy, A lot of people like me, and I am optimistic).     

African American children's reports of depressed mood, hopelessness, and suicidal ideation and later suicide attempts

This study attempted to assess whether family demographic characteristics and child aggressive behavior are equal to or better than child self-reported depressive symptoms in predicting suicidal behavior. Participants were a community population of African Americans first recruited at age 6 and followed periodically through age 19-20. Measures included child self-reports of depressed mood, hopelessness, and suicidal ideation, teacher reported child aggression in grades 4-6, 6 th grade caregiver report of family demographic characteristics, and the participants' report at age 19-20 of suicide attempts. Depressed mood proved the most consistent predictor of adolescent/young adult attempts in our logistic regression analyses of the data from the population as a whole and among females. The relationship between depressed mood and suicide attempts in males was in the expected direction, but was not statistically significant. Teacher-reported youth aggressive behavior did prove to be a significant predictor of attempts in 4 th and 5 th grade for the population as a whole, but not in our analyses by gender. The relationships between family demographic characteristics and attempts failed to reach statistical significance, but were, generally, in the expected direction. The study revealed that African American children's self-reports of depressed mood as early as grade 4 may prove useful in predicting adolescent/young adult suicide attempts, particularly among females. Neither family demographics nor teacher-reported child aggressive behavior proved equal to child self-reported depressive symptoms in predicting later suicide attempts.     

Perceived racism, discrimination, and acculturation in suicidal ideation and suicide attempts among black young adults

During young adulthood the suicide rate among Blacks rises dramatically and approaches that of the U.S. general population, requiring that prevention efforts include a focus on Black young adults. Although most research on suicidality among Blacks has focused on risk factors observed in the dominant culture, in this study the authors examined associations between perceived discrimination, racism, and acculturation with lifetime suicidal ideation (SI) and suicide attempt (SA) among Black young adults. Two hundred fifty Black or African American individuals aged 18-24 residing in a midsize northeastern city were recruited to participate through advertisements. Participants filled out self-report questionnaires. Logistic regressions were used to examine the association of each predictor with SI and SA. Greater perceived acculturation was associated with SI in univariate and multivariate models. There were no other statistically significant results concerning the predictors of interest. The link between perceived acculturation and SI is consistent with limited available data, indicating the need for further study including the potential mechanism(s) for the association. Limitations include the cross-sectional design and reliance on subjective measures.     

Suicide and suicide attempts in the European Economic Community: an analysis of trends, with special emphasis upon trends among the young

An attempt is made to explain the increase in adolescent suicidal behavior reported for most countries in the European Economic Community over the last two decades, within the framework of a social learning theory. A typology of suicidal acts based on an outcome-expectancy model is proposed that would make intelligible the observed positive correlation between the incidence of lethal and nonlethal suicidal acts, the latter having grown to epidemic proportions among the young. This epidemic can be attributed to the interplay of three groups of factors, namely, the socialization of a specific problem-solving behavior repertoire, socioeconomic conditions, and attitudes toward suicide. The implications for suicide prevention are briefly discussed.     

Externalizing problems,internalizing problems,and suicidal ideation in Singaporean adolescents: Sex differences

Adolescent suicide is considered a worldwide problem and an increasing source of concern in Singapore. This study explores the relationships among four factors of maladjustment (that is, emotional distress, negative self, antisocial behavior, and anger control problems) and suicidal ideation in two hundred and seventy-one adolescents from Singapore. Findings from the study indicated that emotional distress, negative self-concept, and antisocial behavior significantly predicted suicidal ideation for the whole sample. Beta weight is largest for emotional distress, followed by negative self, and then antisocial behavior. For females, only emotional distress significantly predicted suicidal ideation. Implications of these findings with regard to working with adolescents with suicidal ideations are discussed. Funding for this research is facilitated by grant RP 1/01 APH.     

Psychopathology associated with suicide attempts among rural adolescents of China

This case control study examined the relationship between psychopathological profiles and self-reported suicide attempts among rural adolescents of China. Cases consisted of 142 adolescents who reported a suicide attempt in the past 6 months in a questionnaire survey (n=1365). An equal number of adolescents without reporting a suicide attempt, matched on age, gender, and school class, were selected from the same survey sample as controls. The Youth Self Report (YSR) was used to assess psychopathological profiles for suicide attempters and matched controls. Results indicated that 73% of suicide attempters had at least one behavioral/emotional syndrome, significantly higher than in controls (30%). Logistic regression analyses showed that anxiety/depression (OR = 3.68) and aggression (OR = 5.02) were each significantly associated with increased risk of suicide attempts after controlling for other behavioral problems. These findings demonstrated the independent contribution of anxiety/depression and aggression to suicide attempts in Chinese adolescents.     

Substance use, suicidal ideation and attempts in children and adolescents

Using data from a community sample of youth ( N = 1,458; ages 9-17), this study assessed the association between adolescent substance use/abuse and suicidal behaviors. Suicide attempts were strongly associated with alcohol abuse and dependence, followed by frequent cigarette smoking. The associations remained significant even after controlling for depression. The associations between substance use/abuse and suicidal ideation were no longer significant after controlling for depression. These findings highlight the important role that substance use plays in adolescent suicidal behaviors.     

Sex differences in self-concept among African adolescents

To examine sex differences in self-concept among black African adolescents in Umtata, South Africa, 97 boys and girls whose mean ages were 18.0 and 17.7 yr., respectively, were drawn from St. John's College students who were in their final year of high school and were preparing for their final year and national matriculation examinations. On the Canadian Self-esteem Inventory mean scores obtained by girls and boys were not significantly different.     

Contributors to suicidal ideation among bipolar patients with and without a history of suicide attempts

This study was designed to develop models for vulnerability to suicidal ideation in bipolar patients. Logistic regression models examined correlates of suicidal ideation in patients who had versus had not attempted suicide previously. Of 477 patients assessed, complete data on demographic, illness history, and personality variables were available on 243. The regression models achieved positive predictive values of 55% and 59% for the attempter (N = 92) and nonattempter groups (N = 151), respectively. Depression was cross-sectionally associated with suicidal ideation in both the attempter and nonattempter groups but made a smaller contribution among attempters. Poor psychosocial adaptation and the personality factor "openness" were stronger contributors to suicidal ideation among prior attempters while anxiety and extraversion appeared protective against ideation. Among nonattempters, depression, anxiety, and neuroticism were the predominant influences on suicidal ideation. Bipolar patients with suicidal ideation may benefit from different treatment strategies depending on their prior attempt status.     

An investigation of differences between self-injurious behavior and suicide attempts in a sample of adolescents

Data from 390 high school students were collected to examine potential differences between adolescents who had attempted suicide and those who engaged in self-injurious behavior on measures of depression, suicidal ideation, and attitudes toward life and death. Significant differences were found between controls and the self-harm groups on all dependent variables. A significant difference on attitudes toward life was found between the self-injury and suicide attempt groups. Post-hoc regression analyses showed that measures of depression, suicide ideation, and attitudes towards life predicted participants' self-harm categorization. These findings provide preliminary evidence that self-injurious behavior is different from attempted suicide among a community sample of adolescents.     

Sex, ethnic, and social differences in test anxiety among Israeli adolescents

The effects of sex, ethnicity, and social class on levels of test anxiety were examined among a sample of 416 adolescent students in Israel. Significant sex differences in mean levels of test anxiety were found, with girls scoring consistently higher than boys across ethnic, social, and grade categories. Pupils of low socioeconomic status (SES) also scored consistently higher than pupils of high SES across grades. Nevertheless, this study provides little support for the commonly held view that sociocultural or sex group differences in school achievement are due, in any meaningful way, to differences in test anxiety. The group differences, though significant for SES and sex, were of negligible magnitude, and the correlation between test anxiety scores and grade point average was minimal for the group as a whole and nonsignificant for students of Eastern background, who have been purported to be particularly affected by high levels of test anxiety. The findings do support other cross-cultural studies, which have found only a modicum of shared variance between test anxiety and grades. It is concluded that test anxiety is not a particularly valid predictor of achievement or ability.     

Gender differences in the psychosocial correlates of suicidal ideation among adolescents.

Gender differences in the psychosocial correlates of suicidal ideation were studied. A sample of 613 high school students (ages 14-19) completed measures of suicidal ideation, depression, hopelessness, life stress, loneliness, alcohol and drug use, and reasons for living. The results of a discriminant function analysis indicated that males reported higher loneliness and substance abuse scores than females whereas females reported greater suicidal ideation, depression, and reasons for living. The results of multiple regression analyses found that, although the same four variables, depression, hopelessness, substance abuse, and few reasons for living emerged as significant predictors of suicidal ideation in both samples, the predictive equation accounted for more of the variance in ideation scores in females (57%) than in males (46%). In a final analysis a discriminant function analysis of the subscales of the reasons for living inventory revealed that females have a greater fear of death and injury whereas males have a greater fear of social disapproval over having suicidal thoughts. This may account for the greater rate of suicide completing among males. Fear of social disapproval, more anger and impulsivity, and less help-seeking behavior among males are offered as potential variables to explain the observed gender differences.     

Risk factors associated with suicide attempts and other self-injury among Hong Kong adolescents

This study examined 1,361 Chinese adolescents who reported self-injurious behaviors. Groups A and B both acknowledged deliberate self-injury, but only Group A had made a suicide attempt. Group C reported accidental self-injury. Deliberate self-injurers (Groups A and B) were more frequently girls, older, and with more suicidal ideation. Group A had more psychopathology, environmental and suicide-related risk factors than group B and C. Group C had higher depressive symptoms than noninjured controls. The study clarifies differences among self-injurious behavior groups based on expressed deliberate self-injury and self-reported suicide attempt. These three groups appear to present a continuum of risk.     

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.     

Current suicide ideation and prior suicide attempts of bipolar patients as influences on caregiver burden

We examined whether caregivers of bipolar patients reporting current suicidal ideation and/or a history of a suicide attempt reported higher levels of burden and/or poorer health compared to caregivers of patients without these suicidality indices. In a cross-sectional design, caregivers (N = 480) associated with (a) patients with current suicidal ideation or (b) patients with a positive lifetime history of at least one suicide attempt, reported lower general health scores than caregivers associated with patients with neither of these indices. Parents of patients with at least one lifetime attempt reported more burden secondary to role dysfunction than spouses. Levels of depression in caregivers varied with whether the caregiver was a spouse or a parent, and whether patients had a history of suicide attempts, current suicidal ideation, or both.     

Affective, behavioral, and cognitive functioning in adolescents with multiple suicide attempts

The purpose of this study was to examine affective, behavioral, and cognitive functioning in adolescents with multiple suicide attempts. Forty-seven adolescents with a history of multiple suicide attempts (MA) were compared to 74 single suicide attempters (SA) on psychiatric diagnosis, depressive symptoms, affect regulation, self-mutilation, alcohol use, and hopelessness. Results revealed that the MA group was more likely to be diagnosed with a mood disorder, and reported more severe depressive symptoms and anger, in comparison to the SA group. Behaviorally, the MA group had higher rates of disruptive behavior disorders and higher levels of affect dysregulation and serious self-mutilation than the SA group. Further, greater levels of hopelessness were reported by the MA than the SA group. After controlling for a mood disorder diagnosis, only differences in anger, affect dysregulation, and serious self-mutilation remained significant. Overall, results suggest that treatment with adolescent suicide attempters might specifically target anger and affect dysregulation to reduce risk for future suicidal behavior.
