Suicidal Behavior Among Homeless and Runaway Adolescents

The present study considered risk factors associated with suicidal ideation and the likelihood of a suicide attempt in a sample of 297 homeless and runaway youth from four Midwestern states. It was hypothesized that sociodemographic characteristics, family factors, suicide exposure, street factors, externalizing behavior, and internalizing behavior would be related to suicidal ideation and to the likelihood of a suicide attempt. It was also hypothesized that suicidal ideation would mediate the relationship between the other predictor variables and the likelihood of a suicide attempt. Over half the sample (53.9%) endorsed some level of suicidal ideation, and over one quarter (26.3%) attempted suicide in the year prior to the interview. Univariate and multivariate results indicated that sexual abuse by a family member, knowing a friend who attempted suicide, drug abuse, and internalization were highly related to suicidal ideation. In the absence of suicidal ideation, sexual abuse, sexual victimization while on their own, and internalization were highly related to the likelihood of a suicide attempt. Finally, the hypothesized mediating effect was found for both sexual abuse and internalization.     

Racial/Ethnic Discrimination and Suicidal Ideation in Emerging Adults: The Role of Traumatic Stress and Depressive Symptoms Varies by Gender not Race/Ethnicity

Drawing from Race-Based Traumatic Stress theory, the present study examined whether traumatic stress and depressive symptoms differentially help explain the relation between racial/ethnic discrimination and suicidal ideation across gender and racial/ethnic groups. A racially/ethnically diverse group of emerging adults (N?=?1344; M_age?=?19.88, SD?=?2.25; 72% female; 46% Hispanic) completed a battery of self-report measures. A cross-sectional design was employed with a series of hierarchical linear regression models and bootstrapping procedures to examine the direct and indirect relation between racial/ethnic discrimination and suicidal ideation through traumatic stress and depressive symptoms across gender and race/ethnicity. The findings suggest an indirect relation through depressive symptoms, but not traumatic stress, and a serial indirect relation through traumatic stress to depressive symptoms in young women and young men, the latter of which was stronger in young women. The indirect relations did not vary by racial/ethnic group. Cumulative experiences of racial/ethnic discrimination may impact suicide-related risk via increases in psychiatric symptomology (i.e., traumatic stress and depressive symptoms), particularly in young women. Racial/ethnic discrimination experiences should be accounted for as a potential source of psychological distress in the assessment, diagnosis, and treatment of suicidal thoughts and behavior, especially among young women endorsing traumatic stress and depressive symptoms. Further research is warranted to better understand the gender difference in the relation between racial/ethnic discrimination and suicide-related risk.

     

Differences in Non-Suicidal Self-Injury and Suicide Attempts in Adolescents

As suicide attempts and self-injury remain predominant health risks among adolescents, it is increasingly important to be able to distinguish features of self-harming adolescents from those who are at risk for suicidal behaviors. The current study examined differences between groups of adolescents with varying levels of self-harmful behavior in a sample of 373 high school students with a mean age of 15.04 (SD = 1.05). The sample was 48% female and the distribution of ethnicity was as follows: 35% Caucasian, 37.2% African-American, 16% Multi-ethnic, 9.2% Hispanic, and 2.3% Asian. The sample was divided into three groups: no history of self-harm, non-suicidal self-injury (NSSI) only, and NSSI in addition to a suicide attempt. Differences in depressive symptoms, suicidal ideation, social support, self-esteem, body satisfaction, and disordered eating were explored. Results indicated significant differences between the three groups on all variables, with the no self-harm group reporting the lowest levels of risk factors and highest levels of protective factors. Further analyses were conducted to examine specific differences between the two self-harm groups. Adolescents in the NSSI group were found to have fewer depressive symptoms, lower suicidal ideation, and greater self-esteem and parental support than the group that also had attempted suicide. The clinical implications of assessing these specific psychosocial correlates for at-risk adolescents are discussed.     

Restrictive Emotionality,Depressive Symptoms,and Suicidal Thoughts and Behaviors Among High School Students

Depression and suicidal thoughts and behaviors are prevalent among youth today. The current study sought to further our understanding of the correlates of depression and suicidality by assessing the relationship between restrictive emotionality (difficulty understanding and expressing emotions) and depressive symptoms and suicidal ideation and attempts among adolescents. A large group of high school students (n = 2189, 58.3% male; 13–18 years of age) completed a self-report survey as part of a 2-stage suicide screening project. Logistic regression analyses were used to assess the association between restrictive emotionality and depressive symptoms, suicidal ideation, and suicide attempts. Those reporting high restrictive emotionality were 11 times more likely to have elevated depressive symptom scores, 3 times more likely to report serious suicidal ideation (after controlling for depressive symptoms), and more than twice as likely to report a suicide attempt (after controlling for depressive symptoms) than those reporting low restrictive emotionality. Restrictive emotionality partially mediated the relationship between depressive symptoms and suicidal ideation and behavior. The pattern of association between restrictive emotionality and the outcome variables was similar for boys and girls. Restrictive emotionality is highly associated with elevated depressive symptoms and suicidal thoughts and behaviors among high school students, and may be a useful specific target in prevention and treatment efforts.     

Sex differences in the causes of adolescent suicide ideation

A model that incorporates both socioenvironmental and psychological factors was developed in an attempt to explain adolescent suicide ideation. A sample of 407 high school students was used to test the model. Most of the previous research on the causes of adolescent suicidal behavior has not used multivariate data analysis techniques and has failed to explore sex differences. Results of the present study suggest that these are important omissions. Although significant at the zero-order level, factors such as self-esteem and interpersonal problems at school were not related to suicide ideation when the effects of the other explanatory variables were controlled. The incidence of suicide ideation was higher for females. Emotional problems and involvement in delinquent behavior were important predictors of ideation for females, while employment problems were the most potent predictor for males.Received his Ph.D. from Florida State University.

The Relative Influence of Different Domains of Social Connectedness on Self-Directed Violence in Adolescence

Previous research has linked greater social connectedness with a lowered risk of self-directed violence among adolescents. However, few studies have analyzed the comparative strength of different domains of connectedness (e.g., family, peers and school) to determine where limited resources might best be focused. Data to address that gap were taken from the Centers for Disease Control and Prevention’s Student Health and Safety Survey, administered to 4,131 7th–12th graders (51.5% female; 43.8% Hispanic; 22.6% African American or Black). Logistic regressions (controlling for age, gender, race/ethnicity, family structure, academic performance, and depressive symptoms) suggest that family connectedness was a stronger predictor than connectedness to peers, school, or adults at school for non-suicidal self-harm, suicidal ideation, suicide plans, and non-fatal suicidal behavior. In some analyses, peer connectedness was unexpectedly a risk factor. Results have implications for prevention of suicide in adolescence, especially in the context of the current trend towards school-based prevention programs.     

Youth Engagement and Suicide Risk: Testing a Mediated Model in a Canadian Community Sample

Suicide is a leading cause of death among adolescents in many industrialized countries. We report evidence from a mediation model linking greater youth activity engagement, spanning behavioral and psychological components, with lower suicide risk through five hypothesized intrapersonal and interpersonal mediating factors. Self-report survey data (15% French, 85% English) were gathered from a community sample of 5,015 Canadian adolescents participating in a mental health promotion program. Youth (M _age = 15.77, SD = 1.42, 50% female) were from two urban centers in southern Ontario, Canada. Youth engagement (youth’s most important type of activity, frequency of involvement, and psychological engagement), suicide risk predictive factors (self-esteem, current concerns, depressive symptoms, coping ability, and connections with others), and suicide risk (ideation and attempts) were assessed. Consistent with the hypothesized mediation model, enjoyment and stress in youth’s most important activity and various activity types were associated with the various hypothesized suicide risk predictive factors, which in turn were related to suicide risk. Implications for conceptualizations of youth engagement as a multidimensional construct and for suicide risk prevention efforts are discussed.     

The Potential Role of Meaning in Life in the Relationship Between Bullying Victimization and Suicidal Ideation

Adolescent bullying is a common problem in schools across America. The consequences of bullying are significant, and can include severe psychological trauma and suicide. A better understanding of the mechanisms that link bullying and suicidal ideation is needed in order to develop effective prevention and intervention initiatives. Meaning in life is a potential mechanism that has not been studied in this context. It was hypothesized that meaning in life could serve as both a mediator and a moderator of the relationship between bullying victimization and suicidal ideation. As a mediator, meaning in life is considered to explain why bullying victimization leads to suicidal ideation. As a moderator, meaning in life is considered to buffer the ill effect of bullying victimization on suicidal ideation. Data collected from an ethnically diverse sample of 2,936 (50 % female), 6th–12th grade students from one urban school district in the Northeastern US were used to examine the hypotheses. The model for girls was consistent with mediation (i.e., meaning in life may explain how victimization leads to suicidal ideation). The model for boys was consistent with moderation (i.e., the ill effect of victimization on suicidal ideation was attenuated as meaning in life increased). Implications for prevention are discussed.     

Suicidal Ideation and Distress Among Immigrant Adolescents: The Role of Acculturation, Life Stress, and Social Support

Acculturative stress and social support play important roles in suicide-related phenomena among adolescent immigrants. To examine their contributions, measures of acculturative and general life stress and a measure of multiple sources of social support were used to predict psychological distress and suicidal ideation among Korean-born high school students residing in the US. Korean students who were sojourning without both parents were compared to Korean students who immigrated with both parents, Korean students who remained in Korea, and American high school students in the US (total N = 227; 56.8% female). The sojourning group reported higher levels of life stress, distress, psychological symptoms, and suicidal ideation than the other groups. Within the two acculturating groups, levels of distress, symptoms, and suicidal ideation were associated with life stress, lack of parental support, and not living with both parents. The findings have important implications for suicide prevention among immigrant adolescents, and imply that parental support is particularly protective.     

Characteristics and Co-occurrence of Adolescent Non-Suicidal Self-Injury and Suicidal Behaviours in Pediatric Emergency Crisis Services

During the potentially tumultuous adolescent period, non-suicidal self-injury (NSSI) and suicide attempts are relatively common, particularly amongst youth who present to mental health services. These phenomena frequently co-occur but their relationship is unclear. This study evaluated clinical data from 468 youth between the ages of 12 and 17 years (63.5% female) to determine the incidence of NSSI 24 h prior to presentation at emergency crisis services, evaluated the overlap between NSSI and suicide attempt, and examined the characteristics of different types of self-harm. Half of the adolescents presenting to emergency crisis services had self-harmed within the previous 24 h, with most of these (91%) classified as NSSI only. The percentage of youth with a suicide attempt was 5% and the co-occurrence of these two behaviours was 4%. Group differences in depressive symptoms, suicidal ideation and impulsivity were identified, with the co-occurring NSSI and suicide attempt group presenting with the highest level of psychopathology. This study underscores the necessity of assessing suicidal ideation and NSSI in all youth presenting to mental health services.     

Changes in noneconomic political attitudes of Southern and Northern youth, 1970s to 1980s

This paper examines changes that occurred in the political attitudes of Southern and Northern youth from the 1970s to the 1980s. National survey data from the National Opinion Research Center is used. Considering attitudinal changes of people under 30, it appears that trends toward greater political tolerance and greater support for racial and sexual equality will continue in the future. However, this study finds a reversal of the usual trend of greater political tolerance among young people. The United States is increasing in conservatism on the social issues. Aside from the social issues, younger people have not become more conservative with age. Important regional differences in attitude changes are indicated.Recieved Ph.D. from University of Iowa. Research interests include political tolerance and public opinion.     

The onset of suicidal ideation in childhood and adolescence

Event history analysis is used to address questions about the timing of first suicidal ideation during preadolescence and adolescence. Are suicidal thoughts atypical during development? Does the age trajectory of suicidal thoughts parallel that of suicidal actions? Do factors that moderate the risk of suicidal actions also moderate the risk of suicidal thoughts, and does their influence vary by developmental stage? Based on life history data from 364 college students, results indicate that suicidal thoughts in childhood are typical and that the risk of such thoughts begins to increase by age nine. Risk rates are affected by demographic factors (gender, race) and by the experience of parental absence. However, the influence of these factors depends on developmental stage, with whites being at increased risk only during adolescence, and parental absence having its strongest effect during preadolescence. In sum, this study suggests that many children and adolescents contemplate suicide, that the risk of doing so begins to increase at an early age, and that clear similarities exist between those groups at heightened risk for suicidal thought and those at heightened risk for suicidal action. Moreover, this study illustrates the power of employing an analytic technique suitable for modeling transitions. Finally, it highlights the need to model differential influences on suicidal ideation at different stages in development.     

Attachment,individuation, and risk of suicide in late adolescence

Security of attachment and level of individuation from parents and peers was examined among 126 undergraduates, 42 with a history of suicidality, 42 who were currently depressed with no history of suicidality, and 42 normal controls. Suicidality was defined as history of serious suicidal ideation or suicide attempt. As predicted, students with a history of suicidality exhibited both the lowest security of attachment as well as the least degree of individuation in their current relationships with parents. In contrast, they were similar to depressed and control students on security of peer attachment and level of individuation from peers. Students with a history of suicidality rated their parents and mother as emotionally absent in childhood to a significantly higher degree than depressed and normal controls. This effect was independent of depression but not from gender. History of suicidality is more strongly associated with family instability than with parental divorce. Absence of parents as emotionally available attachment figures at a time when such availability is critical heightens adolescents' vulnerability to suicide.This research is based on the author's doctoral dissertation in clinical psychology, Boston University.

Developmental Trajectories of Prejudice and Tolerance Toward Immigrants from Early to Late Adolescence

Adolescence is an important period for the development of relationships between immigrants and non-immigrants, yet little is known about how problematic personality traits affect adolescents’ relationships with and attitudes toward immigrants. This work identified the roles of intergroup relationships and one dimension of problematic personality traits, namely callous–unemotional traits, in the development of adolescents’ tolerance and prejudice. Three annual measurements of a large community sample (N = 1,542) of non-immigrant adolescents (M _age = 15.31 at first measurement; 50.2 % girls) were used to show that tolerance and prejudice toward immigrants represent two dimensions with distinct developmental trajectories from early to late adolescence. Callous–unemotional traits predicted fewer decreases in prejudice toward immigrants, yet were not directly associated with tolerance. Intergroup friendships predicted stronger increases in tolerance, which, in turn, predicted decreases in prejudice toward immigrants. Thus, tolerance and prejudice toward immigrants seem to be differentially influenced by social experiences and problematic personality traits.     

Psychosocial Factors Contributing to Adolescent Suicidal Ideation

This study aimed to investigate the family, school, peer and psychological factors that contribute to adolescent suicidal ideation. The participants were 1,358 (680 boys and 678 girls) Hong Kong Chinese adolescents who were divided into younger (12.3 years, n=694) and older (15.4 years, n=664) age groups. By using structural equation modeling, the results showed that family cohesion and sense of school belonging were the core predictors of self-esteem and depression, and that depression was a strong mediator of suicidal ideation. In the prediction of suicidal ideation, peer support was significant among girls and younger adolescents only, whereas peer conflict was significant among older adolescents only. Family conflict, teacher support and academic pressure did not show any significant contribution in the prediction. The implications for future research and positive youth development programs are discussed. Rachel C. F.

Bullying Victimization and Adolescent Self-Harm: Testing Hypotheses from General Strain Theory

Self-harm is widely recognized as a significant adolescent social problem, and recent research has begun to explore its etiology. Drawing from Agnew’s (1992) social psychological strain theory of deviance, this study considers this issue by testing three hypotheses about the effects of traditional and cyber bullying victimization on deliberate self-harm and suicidal ideation. The data come from a school-based survey of adolescents in a rural county of a southeastern state (n = 426); 50% of subjects are female, their mean age was 15 years, and non-Hispanic whites represent 66% of the sample. The analysis revealed that both types of bullying are positively related to self-harm and suicidal ideation, net of controls. Moreover, those relationships are partially mediated by the negative emotions experienced by those who are bullied and partially moderated by features of the adolescent’s social environment and self. Regarding the latter, exposure to authoritative parenting and high self-control diminished the harmful effects of bullying victimization on self-harm and suicidal ideation. The article concludes by discussing the implications of these conclusions for future research and for policy efforts designed to reduce self-harm.     

Vulnerability to Friends’ Suicide Influence: The Moderating Effects of Gender and Adolescent Depression

This paper examines whether severity of depression reduces or intensifies the relationship between friends’ suicide attempt and adolescent's own attempt to commit suicide, and whether there are gender differences in this interrelationship. Using logistic regression and data from a nationally representative sample of adolescents studied at 2 points in time, this study yielded significant findings. First, friends’ suicide attempt and adolescent depression each predicts adolescent's own attempt to commit suicide, and these effects are similar for both boys and girls. Second, highly depressed adolescents are less likely than low- or nondepressed adolescents to attempt suicide when their friends attempt suicide, and this relationship is observed mainly among adolescent boys. Finally, for adolescent girls, depression reduces the relationship between friends’ suicidal attempt and adolescent's own attempt but this effect is not statistically significant. These results are discussed in light of their theoretical importance and policy implications.Professor of Sociology at San Diego State University.

Ethnic Identity in Context: Variations in Ethnic Exploration and Belonging within Parent,Same-ethnic Peer,and Different-ethnic Peer Relationships

Within an ethnically diverse sample of young adults (n = 223, 26% Latin American, 14% Asian American, 32% Filipino American, 28% European American), average levels of ethnic identity was found to vary significantly across different relational contexts. Regardless of ethnicity, young adults reported highest levels of ethnic exploration and ethnic belonging with parents, followed by same-ethnic peers, then different-ethnic peers. Significantly greater variation between relational contexts generally was found for ethnic exploration compared to ethnic belonging. Greater variation in ethnic identity, particularly between same-ethnic and different-ethnic contexts was associated with lower self-esteem, positive affect, relational competence, and higher negative affect, though these liabilities were only found for European American youth. The discussion emphasizes the importance of examining ethnic identity as a dynamic construct that can vary as a function of relationships, and proposes directions for future research.

Acculturative Stress,Perceived Discrimination,and Vulnerability to Suicide Attempts Among Emerging Adults

Cultural factors are often neglected in studies of suicidal behavior among emerging adults. The present study examined acculturative stress and perceived discrimination as statistical predictors of a suicide attempt history among an ethnically diverse sample of 969 emerging adults, ages 18–25 (M = 18.8). Females made up 68% of the sample, and the racial/ethnic composition included Asian, Latino, Black, and White (US-born and non-US-born) individuals. There were no statistically significant racial/ethnic differences in endorsement of a suicide attempt history, with an overall rate of 8% in the sample. Asian participants reported higher acculturative stress than all other racial/ethnic groups, while both Asian and Black participants reported having experienced more discrimination in the previous year, compared to other groups. Logistic regression analyses suggested that familial acculturative stress was associated with 2 times higher odds of endorsing a past suicide attempt, overall. More specifically, it was associated with over 2 times higher odds among Asian participants, over 4 times higher odds among Black participants, and over 3 times higher odds among non-US-born White participants, while social acculturative stress was associated with over 3 times higher odds of endorsing a past suicide attempt among Latino participants. Environmental acculturative stress was associated with decreased odds of endorsing a suicide attempt history, overall, but not when examined separately by racial/ethnic group. Perceived discrimination was associated with over 5 times higher odds of a suicide attempt, overall, and specifically was associated with over 3 times higher odds among Latino participants and over 10 times higher odds among White, US-born participants. These findings suggest the importance of addressing culturally-related variables in treatment with emerging adults of racially/ethnically diverse backgrounds to reduce risk for suicidal behavior.     

Functioning of Adolescents With Symptoms of Disturbed Sleep

The objective of the study was to examine the association between disturbed sleep and the functioning of adolescents, in particular cumulative effects on functioning across multiple life domains. Data from a large, school-based survey (n = 5,423) were used to examine the association between eight indicators of psychological, interpersonal, and somatic functioning and symptoms of insomnia and hypersomnia among adolescents. The strongest correlates of insomnia were disturbed mood (OR = 5.9), fatigue (OR = 7.4), and suicidal ideation (OR = 3.4). The same pattern held for hypersomnia, although the associations were not as strong for fatigue (OR = 6.8), mood disturbance (OR = 3.5), and suicide ideation (OR = 2.8). Youths who experienced both insomnia and hypersomnia had greater odds of psychological, interpersonal, and somatic dysfunction than youths who had experienced only one sleep disturbance. Cumulative effects of sleep problems were pronounced, with 27.6% of those with hypersomnia, 41.7% of those with insomnia, and 59.2% of those with both sleep problems reporting three or more types of dysfunction. The results suggest that adolescents experiencing disturbed sleep also experience a range of deficits in functioning. Further, youths with disturbed sleep are more likely to manifest multiple deficits in functioning. From the available evidence, however, it is not possible to specify what the causal pathways are. What are needed are cohort studies designed to examine the association of disturbed sleep and functional impairment among adolescents prospectively.
