Suicidal Ideation Among American Indian Youths

ABSTRACT

Epidemiological data indicate that suicide rates have been decreasing among 15–19-year-olds in the United States; however, rates have been increasing among some minority groups. Research has identified numerous risk factors for adolescent suicide and suicide-related behaviors, but models testing these risk factors within different racial or ethnic groups are scarce. The current study tested a model of adolescent suicide ideation in a sample of 258 high school students, comparing the model fit across two racial groups. The model significantly fit the data for both groups indicating that the relationship between suicide exposure and current suicidal ideation is mediated by reasons for living and level of depressive symptoms. Ways in which the results improve our understanding of risk factors in diverse adolescents are discussed.     

Suicidal and Nonsuicidal Coping Methods of Adolescents

The authors investigated the coping methods used by adolescents hospitalized for suicidal behaviors and adolescents hospitalized for nonsuicidal behaviors. The authors' purpose was to determine if a significant difference between the two groups existed. The findings suggested that adolescents with suicidal thoughts and behaviors use affective-oriented coping methods to a more significant degree than they use problem-solving strategies. The nonsuicidal group was found to use both affective and problem-oriented coping methods.     

Relationship between Academic Stress and Suicidal Ideation: Testing for Depression as a Mediator Using Multiple Regression

Relations among academic stress, depression, and suicidal ideation were examined in 1,108 Asian adolescents 12–18 years old from a secondary school in Singapore. Using Baron and Kenny’s [J Pers Soc Psychol 51:1173–1192, 1986] framework, this study tested the prediction that adolescent depression mediated the relationship between academic stress and suicidal ideation in a four-step process. The previously significant relationship between academic stress and suicidal ideation was significantly reduced in magnitude when depression was included in the model providing evidence in this sample that adolescent depression was a partial mediator. The applied and practical implications for intervention and prevention work in schools are discussed. The present investigation also served as a demonstration to illustrate how multiple regression analyses can be used as one possible method for testing mediation effects within child psychology and psychiatry.     

Family Environment and Suicidal Ideation Among Bipolar Youth

The objective of this study was to examine the association between family environment and suicidal ideation among youth with bipolar disorder. Subjects included 446 bipolar (BP) youth (age 7–17) enrolled in the Course and Outcome of Bipolar Youth study. Current suicidal ideation, family functioning and family stress were assessed at intake. BP youth with current suicidal ideation reported more conflict with their mother and less family adaptability. Ideators endorsed more stressful family events over the prior year and higher rates of specific familial stressors. Clinicians treating bipolar youth should consider family stress when conducting suicide risk assessment. Treatment goals may include enhancing family communication and addressing issues of loss.     

Age Discrimination and Suicidal Ideation Among Korean Older Adults

ObjectiveWe examined the role of age discrimination in suicidal ideation among community-dwelling older adults in South Korea.MethodsWe analyzed adults aged 65 or older residing in Korea drawn from the 2014 Survey of Living Conditions and Welfare Needs of Korean Older Persons (total unweighted n = 10,279; total weighted N = 6,280,588). Data were analyzed using chi-square, t tests, and logistic regression analyses.ResultsResults from logistic regression analysis showed that after adjusting for covariates, Korean elders who experienced age discrimination had 2.26 times higher odds of having suicidal ideation than those who did not.ConclusionsThe experience of age discrimination increased the risk of suicidal ideation among Korean elders. Identifying ways to reduce age discrimination may be an effective means of reducing suicidal ideation, which would, in turn, potentially decrease suicide rates among older adults. There may be cross-cultural clinical implications and variations due to belief systems surrounding respect for older adults.     

Psychosocial Correlates of Suicidal Ideation in Rural South African Adolescents

Suicide is a prevalent problem among young people in Southern Africa, but prevention programs are largely absent. This survey aimed to identify the behavioral and psychosocial correlates of suicidal ideation among adolescents in Limpopo. A two-stage cluster sample design was used to establish a representative sample of 591 adolescents. Bivariate correlations and multiple linear regression analyses were conducted. Findings show that suicidal ideation is prevalent among adolescents. The psychosocial factors perceived social support and negative feelings about the family and the behavioral factors forced sexual intercourse and physical violence by the partner were found to increase the risk of suicidal ideation. Depression mediated the relationship between these psychosocial and behavioral risk factors and suicidal ideation. This study increased our understanding of the psychosocial and behavioral predictors of adolescent suicidal ideation. The findings provide target points for future intervention programs and call for supportive structures to assist adolescents with suicidal ideation.     

Emotional and Social Loneliness as Predictors of Suicidal Ideation in Different Age Groups

Loneliness and suicidal ideation (SI) are relevant issues. This study aimed to examine the prevalence of death ideation (DI) and SI in the general population across four age groups and to determine the extent to which emotional and social loneliness are associated with SI. Data were collected via an online panel in Slovenia in February 2019 on a representative sample of 991 participants (50.5% men) aged 18 years and over. Participants completed a series of questionnaires on loneliness, suicidality, stress, and well-being. DI, SI, and previous suicide attempts were most common among younger participants. In each age group, several factors appeared as important predictors of SI, with emotional loneliness being a significant factor in all groups. Given the role of emotional loneliness in SI, prevention programs should address loneliness and its correlates across age groups.

     

Rumination and Pessimistic Certainty as Mediators of the Relation Between Lifetime Suicide Attempt History and Future Suicidal Ideation

This study examined whether rumination and certainty about pessimistic future-event predictions (P-Certainty) would mediate the relation between lifetime suicide attempt history and future suicidal ideation. Young adults, ages 18–25 (N = 143), with a suicide attempt history (n = 32) or no previous suicide attempt history (n = 111) at baseline, were followed up 2–3 years later and completed measures of rumination, depressive symptoms, hopelessness, suicidal ideation, and pessimistic future-event certainty. Lifetime suicide attempts at baseline were associated with higher suicidal ideation at follow up, and this relation was mediated by rumination and P-Certainty. Suicide attempters may be vulnerable to later ideation due to higher levels of rumination and also certainty in their pessimistic future expectations.     

Parent-Adolescent Acculturation Gap and Suicidal Ideation among Adolescents from an Emergency Department

The objective of this article is to examine the impact of parent-adolescent acculturation gap on vulnerability to suicidal ideation among adolescents presenting to an emergency department with suicidal behavior. A multiethnic sample of adolescents (n?=?43) and their parents (n?=?43) completed an acculturation measure, and adolescents reported on emotion reactivity, hopelessness, depressive symptoms, and suicidal ideation. The direction of the association between suicidal ideation and vulnerability variables varied depending on the size of the acculturation gap. Emotion reactivity was more negatively associated with suicidal ideation the larger the parent-adolescent acculturation gap, while hopelessness was more strongly associated with suicidal ideation the smaller the gap, adjusting for depressive symptoms. Assessments of racial/ethnic minority adolescents at risk for suicidal behavior should address parent-adolescent acculturation gaps.     

Social Support and Stress Among University Students in Jordan

The purpose of this study was to examine the relationship between perception of social support and perceived stress among university students in Jordan. A sample of 241 university students from private and government universities in Jordan answered self-report questionnaires including the perceived social support scale and perceived stress scale. The results showed that university students have moderate perception of social support and stress. Female university students had higher perception of stress and social support than male university students. Perceived stress had a negative correlation with perceived social support from family (−0.29, p < 0.05). The perceived social support from family was a better predictor of perceived life event as stressful situations than perceived social support from friends. The study implications for research and intervention were discussed.     

Sexual Trauma,the Dopamine D4 Receptor,and Suicidal Ideation Among Hospitalized Adolescents: A Preliminary Investigation

Though an association exists between sexual trauma and adolescent suicidal thoughts and behaviors (STBs), not all adolescents with a sexual assault history develop STBs. The present study examined whether carrier status of the DRD4 VNTR polymorphism (DRD4 L vs. DRD4S) moderated the relationship between sexual trauma and STBs in a sample of psychiatrically hospitalized adolescents. A total of 76 psychiatrically hospitalized adolescents provided saliva samples for genotyping procedures and completed assessment measures. Using hierarchical regression analyses, results indicated that DRD4 L carriers with a sexual trauma history reported significantly more severe suicidal ideation than DRD4S homozygotes. There was no interaction evident for the prediction of suicide attempts. To our knowledge, this is the first study to provide preliminary support for synergistic effects of sexual trauma, DRD4, and severity of SI in adolescents. Further studies of the relationship between sexual trauma, DRD4, and STBs utilizing larger samples are needed.     

Active and Passive Problem Solving as Moderators of the Relation Between Negative Life Event Stress and Suicidal Ideation Among Suicide Attempters and Non-Attempters

This study examined whether active problem solving would buffer against, whereas passive problem solving would exacerbate, the association of negative life stress with suicidal ideation. Young adult college students (73 females, M_age = 19.0) from a diverse urban public university, with (n = 37) and without (n = 59) a suicide attempt history completed measures of life stress, problem solving, hopelessness, depression, and suicidal ideation. Hierarchical linear regressions were conducted to test moderating roles of active and passive problem solving, along with suicide attempt history, on the relation between negative life event stress and suicidal ideation. There was a weaker relation between life stress and suicidal ideation at high and average levels of relevant problem solving than at low levels, and this was the case primarily for suicide attempters but not for non-attempters. Individuals with a past attempt produced more passive solutions than non-attempters, but among attempters, even passive problem solving buffered the association of life stress with suicidal ideation. Relevant problem solving in the face of life stress may be especially important for individuals vulnerable to suicidal ideation due to an attempt history. Among such at-risk individuals, generating even passive solutions in the face of life stress may be more adaptive than generating few solutions. Thus, clinical interventions with suicide attempters that focus on generating solutions to problems, even if these are initially passive, may help mitigate the effect of life stress on suicidal ideation.     

The Interaction of Personality and Social Support on Prospective Suicidal Ideation in Men and Women With Late-Life Depression

ObjectiveEvidence suggests a cross-sectional association between personality traits and suicidal ideation in LLD. Yet, it is unclear how personality may influence suicidal ideation over time in LLD, or whether such an association would be moderated by psychosocial and biological individual differences. The present study had three aims: 1) to examine whether personality traits increase suicidal ideation in LLD over time, 2) to understand whether this relationship is influenced by subjective social support, and 3) to determine whether the potential relationship between social support, personality, and suicidal ideation is different for men and women.DesignParticipants were enrolled in the Duke University Neurocognitive Outcomes of Depression in the Elderly (NCODE), a longitudinal investigation of the predictors of poor illness course in LLD. Patients were initially enrolled in the NCODE study between December 1994 and June 2000 and were followed for an average of six years.SettingNCODE operates in a naturalistic treatment milieu.ParticipantsOne hundred twelve participants aged 60 and older with a current diagnosis of major depressive disorder.MeasurementsAnnual assessments of depression, suicidal ideation, and social support (measured with the Duke Social Support Index). Participants also completed the NEO Personality Inventory-Revised (NEO-PI-R) providing measures of the five major personality dimensions (neuroticism, extraversion, openness, conscientiousness, and agreeableness).ResultsUnivariate logistic generalized linear mixed modeling (GLMM) analyses revealed that higher levels of depression at baseline, less subjective social support, higher neuroticism, and lower extraversion were significantly associated with an increased likelihood of suicidal ideation over time. While the relationship between these dimensions and suicidal ideation were no longer significant in multivariate analyses, there was a significant moderating effect of social support on the association between suicidal ideation and certain neuroticism and extraversion personality facets. Decreased subjective social support was associated with an increased likelihood of suicidal ideation in LLD patients with high (but not low) impulsiveness and low (but not high) gregariousness and positive emotions. Across all models, social support was beneficial to women, but not men, in decreasing the likelihood of future suicidal ideation.ConclusionChanges in social support may contribute to suicidal ideation in older depressed adults with certain personality traits. Irrespective of personality traits, changes in social support had a significant effect on the suicidal ideation of women but not men. These relationships were apparent even when controlling for depression severity, age, and history of suicide attempt.     

The Mediating Role of Coping Self-Efficacy in Hope Box Use and Suicidal Ideation Severity

In this study, we examined the indirect effect of the Virtual Hope Box (VHB) smartphone application on suicidal ideation, mediated through coping self-efficacy. A total of 117 veterans with suicidal ideation completed measures on coping self-efficacy and suicidal ideation at baseline and weeks 3, 6, and 12. Participants were randomly assigned to either the VHB or enhanced treatment as usual (eTAU) condition. Parallel process growth curve modeling (?0.20 [95% CI?=??0.44, 0.00]) and auto-regressive modeling (?0.12 [95% CI?=??0.35, ?0.01]) revealed that a higher rate of change in coping self-efficacy in the VHB group was associated with a decrease in suicidal ideation severity, as compared to the eTAU group. Findings suggest that coping self-efficacy may be one mechanism by which the VHB operates to help reduce suicidal ideation. More broadly, the role of coping self-efficacy in reducing suicidal ideation is worthy of future study.
