Suicide prevention on college campuses: What works and what are the existing gaps? A systematic review and meta-analysis

Abstract

Objective: To examine the effects of universal and targeted suicide prevention programs on relevant outcomes in college campuses. Methods: College suicide prevention programs published from 2009 to 2018 were assessed on outcomes including knowledge, skills, self-efficacy, suicidal ideation, and suicidal behaviors. Effects of the interventions on outcome variables with sufficient studies to warrant meta-analysis (ie, knowledge, skills, and self-efficacy) were meta-analyzed. Studies reporting on the remaining outcomes (ie, suicidal ideation and behaviors) were systematically reviewed. Results: Significant increases in suicide prevention knowledge, skills, and self-efficacy were observed in universal prevention interventions that typically employed gatekeeper prevention strategies. Evidence of reductions in suicidal ideation and behaviors was observed across targeted suicide prevention programs for at-risk students. Conclusion: Prevention programs are beneficial for training those likely to come in contact with people endorsing suicidality, but further research is needed to show that suicide interventions can consistently have significant effects on suicidal students as well.     

Spiritual Well-Being and Suicidal Ideation Among College Students

Objective: This study explored whether specific dimensions of spiritual well-being (religious well-being and existential well-being) relate to reduced suicidal ideation, and whether associations persisted after controlling for religiosity and psychosocial variables associated with suicide. Participants: Participants were 457 college students who completed measures that assessed spiritual well-being, religiosity, hopelessness, depression, social support, and suicidal ideation. Methods: The authors used linear regression modeling to assess religious and spiritual correlates of suicidal ideation. Results: After controlling for demographic variables and psychosocial factors, neither involvement in organized religion nor religious well-being significantly contributed to suicidal ideation. However, even after controlling for significant correlates, existential well-being remained a significant predictor of suicidal ideation. Conclusions: This investigation highlighted existential well-being as an important factor associated with lower levels of suicidal ideation among college students. Findings from this study focusing on the association between spiritual well-being and suicidality may prove especially beneficial to suicide prevention efforts.     

Predictors of suicidal ideation among college students: A prospective cohort study

ABSTRACT

This prospective cohort study investigated longitudinal predictors of suicidal ideation among college students. A non-clinical cohort of college students (N = 171) completed baseline and 3-month follow-up surveys. Depressive symptoms, worst-point suicidal ideation, and suicide attempt history significantly predicted follow-up suicidal ideation severity after adjusting covariates. Similarly, depressive symptoms and worst-point suicidal ideation (but not attempt history) were significant predictors of follow-up suicidal ideation intensity in an adjusted model. The results suggest that current depressive symptoms and lifetime worst-point suicidal ideation are independently valuable constructs that may provide relatively short-term predictive information when screening for suicidal ideation among college students.     

Young Adult Suicide and Sexual Orientation

ABSTRACT

The current project focused on the suicidal ideation and risk potential of young adults (N = 312) and explored scores on self-report measures of suicidal ideation inclusive of various sexual orientations. Results suggest that the Lesbian, Gay, and Bisexual (LGB) youth surveyed (N = 73) differ in their display of suicide risk with significantly higher Beck Hopelessness Scale (BHS) and Suicide Probability Scale (SPS) scores. Social support served as a mitigating factor relating significantly to lower levels of hopelessness and suicidal ideation, especially among those LGB participants. The SPS held a significant relationship to suicide attempt in the past year, while the BHS held a significant relationship to suicide attempt in the past six months. Implications for counselors serving young adults are addressed, including specific suggestions to enhance counselor education and supervision related to suicide assessment and LGB counselor competency.     

Health attitudes and suicidal ideation among university students

ABSTRACT

Objective: The purpose of this study was to examine whether positive health attitudes are associated with suicidal ideation among university students after accounting for other health risk factors linked to suicidal ideation. Participants: Participants were 690 undergraduates from a large midwestern university during fall semester 2011. Methods: Participants reported demographics and health characteristics. Regression models compared individuals who reported suicidal ideation and those who did not. Results: In unadjusted models, suicidal ideation was significantly negatively associated with positive health attitudes, and positively associated with depression, drug use problems, sleep problems, and being overweight. In adjusted models, more positive health attitudes continued to be significantly negatively associated with suicidal ideation. Conclusions: This study suggests a link between positive health attitudes and lower probability of suicidal ideation. Additional research is needed to assess enhancing general health attitudes as a suicide prevention effort.     

Perceived need for care and mental health service utilization among college students with suicidal ideation

ABSTRACT

Objective: This study aimed to identify correlates of service utilization and perceived need for care among college students with suicidal ideation. Participants: Respondents were recruited from introductory psychology courses at an undergraduate college during the Fall 2014 semester. Methods: Independent correlates of (1) mental health service utilization, (2) self-perceived need, and (3) other-perceived need for mental health services among college students (N = 190) with suicidal ideation were identified. Results: Service utilization was associated with need for care as perceived by others. Perceived need for care by others was associated with suicidal ideation intensity and suicide attempt history. Perceived need by the respondents themselves was correlated with depression severity, sex, and race but was not independently associated with actual service utilization. Conclusions: Perceived need by others was the sole significant correlate of service utilization, suggesting it is an important target for public health interventions aimed at facilitating pathways into mental health treatment.     

Prevalence and predictors of suicidal ideation,plan, and attempts,in first-year college students with ADHD

Abstract

Objective. The present study evaluated the prevalence of past suicidal ideation (SI), plan, and attempt in college students with ADHD (N?=?102) compared to a matched control (N?=?102). Predictors of SI, plan, and attempts, were examined. Participants. Study participants were first year college students at a large Southeastern university who completed measures during August or September of 2014 or January of 2015. Methods. Measures were completed by first year students via an online survey. Results. Prevalence rates for SI and related behaviors were higher among the ADHD group than the matched control, with suicide attempts rates four times higher in the ADHD group (13.7% vs. 2.9%). Results showed that ADHD predicted rates of SI and suicide attempt accounting for depression and key demographic variables. Conclusions. Findings have implications for suicide risk assessments conducted with college students with ADHD.     

The effects of familial acculturative stress and hopelessness on suicidal ideation by immigration status among college students

Objectives: Based on acculturative family distancing theory, we examined whether familial acculturative stress interacted with hopelessness to predict suicidal ideation differentially among emerging adult immigrant versus nonimmigrant college students. Participants: We recruited 152 generationally and racially/ethnically diverse college students (42 immigrants) from 2012 to 2013. Methods: Participants completed measures of hopelessness, depressive symptoms, ethnic identity, familial acculturative stress, and suicidal ideation. Results: Immigrant status interacted with hopelessness and familial acculturative stress. Hopelessness was associated with less suicidal ideation among immigrants than among nonimmigrants at a familial acculturative stress score below the 11th percentile, but greater suicidal ideation among immigrants than among nonimmigrants at a familial acculturative stress score above the 72nd percentile. Conclusions: Familial acculturative stress may exacerbate the effect of hopelessness on suicidal ideation among immigrant college students, and should be monitored during suicide risk assessment and treatment.     

Suicide Ideation Among College Students Evidencing Subclinical Depression

Abstract

Identifying elevated suicide ideation in college students is a critical step in preventing suicide attempts and deaths by suicide on college campuses. Although suicide ideation may be most prominent in students with severe depression, this should not suggest that only students with severe depression experience significant risk factors for suicide. Objective: The purpose of these 3 studies was to explore the relation between suicide ideation and severity of depressive symptoms in college students. Participants: In each study a sample of college students were recruited for participation. Methods: Participants completed self-report assessments of depressive symptoms and suicide ideation. Results: The results of these studies suggest that although the greatest elevation in suicide ideation occurs at the highest depressive symptoms, significant suicide ideation is also experienced by college students with mild and moderate depressive symptoms. Conclusions: The implications of these findings for the assessment of suicide ideation are discussed.     

Comparison of suicidal ideation,suicide attempt and suicide in children and young people in care and non-care populations: Systematic review and meta-analysis of prevalence

Suicide in children and young people is a major public health concern. However, it is unknown whether individuals who have been in the care of the child welfare system are at an elevated risk. Care is presently defined as statutory provision of in-home care (e.g. child living with birth family but in receipt of legal order involving supervision by social workers) or out-of-home care (e.g. foster care, residential care and kinship care). This paper presents a systematic review and meta-analysis comparing the prevalence of suicidal ideation, suicide attempt and suicide in children and young people placed in care with non-care populations. A systematic search was conducted of 14 electronic bibliographic databases and 32 websites. Of 2811 unique articles identified, five studies published between 2001 and 2011 met the inclusion criteria. Studies reported on 2448 incidents of suicidal ideation, 3456 attempted suicides and 250 suicides. The estimated prevalence of suicidal ideation was 24.7% in children and young people in care compared to 11.4% in non-care populations. The prevalence of suicide attempt was 3.6% compared to 0.8%. Two studies reported on suicide. Suicide risk in children and young people in care was lower in one study (0% vs 0.9%) and higher in the second (0.27% vs 0.06%). The results of the systematic review and meta-analysis confirm that suicide attempts are more than three times as likely in children and young people placed in care compared to non-care populations. Targeted interventions to prevent or reduce suicide attempt in this population may be required. Further comparative studies are needed to establish if children and young people in care are at an elevated risk of suicidal ideation and suicide.     

Suicidal behavior and associated factors in sexually abused adolescents

Objectives

The aim of the present study is to determine the rate of suicidal ideation and suicide attempts in sexually abused adolescents and to determine the factors associated with suicidal behavior.

Method

106 adolescents between the ages of 12–18 (94 girls, 12 boys) who were exposed to sexual abuse and referred for the preparation of forensic reports were included in the study. The investigators retrospectively examined the case files, forensic reports and social worker reports.

Results

It has been found that in cases exposed to sexual abuse, suicidal ideation developed in 63.2% (n = 67) of the individuals and 24.5% (n = 26) of them attempted suicide. The rate of suicidal ideation and suicide attempts was higher in cases who live separately from one or both parents, those who have ASD or PTSD after sexual abuse, cases in which abuse involved penetration, cases who were abused by someone known or someone from the family, cases where sexual abuse was accompanied by coercion and physical violence, and those who were exposed to abuse continuously. Among girls, in cases who have suicide history before sexual abuse and those who were abused by more than one abuser, the rate of suicidal ideation was higher.

Conclusion

It has been shown in many studies that sexual abuse in childhood increases the risk of suicidal behavior. Consideration of the factors associated with suicidal behavior in victims of sexual abuse will be helpful to clinicians in preventing suicide attempts.     

Three Psychotherapies for Suicidal Adolescents: Overview of Conceptual Frameworks and Intervention Techniques

Suicide is the second leading cause of death among youth, and as many as one in five youth report having had at least one serious thought of suicide in the past year. Despite the enormous emotional pain and suffering associated with suicidal thoughts and behaviors, up to 40 % of suicidal youth never receive treatment. Given that social workers are employed in multiple settings where suicidal children and adolescents are encountered (e.g. schools, homeless shelters, emergency departments, outpatient mental health agencies, private practice), they play a critical role in the identification and treatment of suicidal youth. In the past decade, evidence has emerged that attachment-based family therapy, integrated cognitive behavioral therapy, and dialectical behavior therapy can reduce suicidal ideation and/or suicide attempt in youth. The purpose of this article is to review the theoretical assumptions, conceptual frameworks and key intervention techniques for these three interventions so that clinicians can integrate these approaches into their practice with suicidal youth and families. Implications for practice are integrated throughout the review.     

Positive Social Support,Negative Social Exchanges,and Suicidal Behavior in College Students

Abstract

Objective: Risk for suicide is often higher among college students, compared to same-age noncollegiate peers, and may be exacerbated by quality of social support and interactions. The authors examined the independent contributions of positive social support and negative social exchanges to suicide ideation and attempts in college students. Participants: Participants were 439 volunteer undergraduate students, who were primarily female (71%). Methods: Cross-sectional, survey design. Participants completed measures assessing positive social support, including emotional, informational, and tangible support; negative social exchanges; and suicidal behavior, including ideation and attempts. Results: Positive social support, particularly tangible support, and negative social exchanges were significantly predictive of greater suicidal behavior. Conclusions: Practical manifestations of support may buffer against suicide risk for college students, whereas conflict-based interactions may contribute to increased risk. At the institutional, parental, and peer levels, promotion of supportive relationships may be an important suicide prevention strategy.     

A qualitative analysis of suicide risk factors,preferred means,and means restriction feasibility within a homeless shelter environment

Suicide completion rates among homeless individuals are approximately nine times higher than the general population. The purpose of this study was to capture the state of social support among homeless individuals, understand how homeless community members support peers in crisis, examine the awareness of suicidal ideation, identify common methods for suicide, and generate strategies for means restriction within a shelter. Twenty individuals residing at an emergency shelter were interviewed. Participants were of diverse cultural identities overrepresented in the sample relative to the general population. Interviews revealed that 40% of participants lacked social support. However, the majority indicated that if they encountered someone at risk for suicide, they would provide support and encouragement to the at-risk individual. Almost half of participants reported knowing of an individual in the shelter who had previously attempted suicide and/or was currently or previously feeling suicidal. Overdose was identified as a primary method for suicide; however, the majority of participants were unable to generate strategies for means restriction. The present study offers a glimpse into the experience of homeless individuals and provides valuable information regarding risk factors for suicide within this highly marginalized and underserved population.     

Suicidal Ideation and Comorbid Disorders in Adolescents and Young Adults Diagnosed with Asperger's Syndrome: A Population at Risk

ABSTRACT

The purpose of this study was to examine the level of suicidal ideation and comorbid disorders (major depressive disorder, generalized anxiety disorder) among adolescents and young adults with diagnosed Asperger's syndrome (AS). A cross-sectional study using a self-administrated mail questionnaire and a Web-based questionnaire were used. Two samples were selected for this study. The first sample used snowball sampling, starting with parents of adolescents and young adults with diagnosed AS who participated in a qualitative study conducted in 2002. The second sample consisted of a volunteer sample of parents who visited Web sites for parents and individuals with diagnosed autism spectrum disorder. The sample included 10 adolescents and young adults with diagnosed AS. Fifty percent of the sample had a clinically significant level of suicidal ideation, 20% met criteria for a diagnosis of major depressive disorder, and 30% met criteria for generalized anxiety disorder.     

Parent–Child Conflict and Suicide Rumination in College Students: The Mediating Roles of Depressive Symptoms and Anxiety Sensitivity

Abstract

Objective: Parent–child conflict, depressive symptoms, and anxiety sensitivity have each been identified as risk factors for suicide ideation in college students. This study examined the relations among these risk factors and suicide rumination utilizing transition theory to guide the hypothesized relations. Participants: Undergraduate college students participated in this study in the spring of 2012 (January to May). Methods: Participants completed self-report measures of parent–child conflict, depressive symptoms, anxiety sensitivity, and suicide rumination, among other measures. Hypothesized pathways and mediation were tested using path analysis. Results: Suicide rumination was positively and uniquely predicted by depressive symptoms, anxiety sensitivity, and parent–child conflict. The relation between parent–child conflict and suicide rumination was, in part, accounted for by depressive symptoms and anxiety sensitivity. Conclusions: Results suggest that it would be advisable for clinicians to assess for students’ conflicts with their parents in conjunction with their levels of depression and anxiety when assessing for suicide risk.     

Loss by suicide. A risk factor for suicidal behavior

1. Data show suicidal behavior often is precipitated by individuals' experience of loss by suicide. This article focuses on three potential links between the two phenomena (i.e., grief experienced by suicide survivors and familial risk factors for suicide; suicide clusters and pacts; consequences of mass media portrayals of suicide). 2. Suicide bereavement has certain typical characteristics that comprise the "suicide survivor syndrome" and may be linked with increased risk of suicidal ideation and behavior. 3. Individuals' suicidal behavior and ideation can lead to suicide clusters (i.e., a group of suicides or attempts occurring close together in time and space) and pacts (i.e., mutual agreements between two people who promise to kill themselves at the same time, often in the same place). 4. Mass media portrayals of suicide may lead to imitative suicides (i.e., the "Werther effect").     

Improving youth mental health through family-based prevention in family homeless shelters

This exploratory study examines changes in suicidal ideation among a sample (N = 28) of homeless youth, ages 11–14, residing within family shelters in a large metropolitan area. Changes in suicidal ideation from pretest to posttest are compared across two group approaches to delivering HIV prevention. Youth and their families participating in the HOPE Family Program, incorporating a family strengthening approach, are compared to those receiving a traditional health education-only approach. Multivariate analyses reveal that youth in the HOPE Family Program were 13 times more likely to report a decrease of suicidal ideation. These findings indicate that health education programs integrating a family strengthening approach hold promise for positively impacting mental health outcomes for vulnerable youth.     

Suicide Ideation Among US College Students Associations With Other Injury Risk Behaviors

Abstract

Suicide, the endpoint of a continuum that begins with suicide ideation, is the third leading cause of death among the US college-aged population. The first and second leading causes of death among this age group, unintentional injury and homicide, may also be linked to suicide ideation. We used data from the National College Health Risk Behavior Survey to examine the association between suicide ideation and injury-related behaviors among 18- to 24-year-old college students. Students who reported suicide ideation were significantly more likely than students who did not report considering suicide to carry a weapon, engage in a physical fight, boat or swim after drinking alcohol, ride with a driver who had been drinking alcohol, drive after drinking alcohol, and rarely or never used seat belts. Given this clustering of injury-related risk behaviors, college prevention programs should aim to reduce risks for injuries comprehensively, rather than addressing each risk behavior separately.
