Testing a model of suicide ideation in college students

This study examined several risk factors-negative life events (NLE), hopelessness, and depressive symptoms-believed to commonly precipitate suicide ideation in college students. A total of 345 undergraduates participated in the study. Students completed four self-report questionnaires. Hierarchical regression analyses were used to construct a risk model of suicide ideation. This study confirmed depressive symptoms and hopelessness as predictors of suicide ideation in college students; however, NLE impacted suicidal thoughts through hopelessness and depressive symptoms. Interestingly, depressive symptoms exerted a stronger influence on suicide ideation than hopelessness. Hopelessness served as a partial mediator in the relationship between NLE and depressive symptoms; however, depressive symptoms fully mediated the relationship between NLE and hopelessness. Clinical implications for understanding suicide risk in college students are discussed.     

Multidimensional Future Time Perspective as Moderators of the Relationships between Suicide Motivation,Preparation, and Its Predictors

The moderating impact of future time perspective (FTP) components on the relationships of hopelessness, depressive symptoms, and psychache with suicide motivation and preparation was investigated. In a sample of first year college students (N = 87) recruited on the basis of elevated suicide ideation and depressive symptoms, future thinking, optimism, and future connectedness attenuated the relationship of suicide motivation with depressive symptoms and hopelessness. Future thinking moderated the impact of depressive symptoms on suicide preparation. No moderating effects were found for psychache. This study demonstrates that FTP may buffer against the worst effects of salient suicide predictors among high‐risk students.     

Relationship Between Religious Coping and Suicidal Behaviors Among African American Adolescents

This study investigated whether hopelessness and depression were risk factors for suicidal thoughts and behaviors in African American adolescents and looked at whether religious participation and religious coping protected these students from suicidality. Participants were 212 African American high school students (133 females, 79 males). The results of multiple and logistic regression analyses found that hopelessness and depression were risk factors for suicidal ideation and attempts. Religious coping style was significantly related to suicidal behaviors: Self-directed coping was related to increased hopelessness, depression, and suicide attempts, and collaborative coping was related to increased reasons for living. Gender differences were found in symptoms of depression, religious coping style and religious participation. Results provide additional support for suicide interventions to target hopelessness and depressive symptoms and highlight the importance of examining the role of culturally salient variables, such as religious participation and religious coping style, when developing intervention programs for suicide.     

Suicidal ideation and attitudes toward suicide

Although hopelessness and depression are known risk factors for suicide, most individuals who are hopeless or depressed never make a suicide attempt. In this study, we tested the hypothesis that college students' (n = 230) attitudes toward suicide (the degree to which they see it as an acceptable option under some circumstances) would moderate the link between both hopelessness and depressive symptoms and their levels of suicidal ideation. This moderation hypothesis was supported, but only among men. Specifically, among men, levels of hopelessness and depressive symptoms were significantly related to suicidal ideation among only those with relatively positive attitudes toward suicide.     

Mediators of the Daily Hassles–Suicidal Ideation Link in African American Women

Depressive symptoms and hopelessness as mediators of the daily hassles–suicidal ideation link in low‐income African American women exposed to intimate partner violence (n = 100) were investigated. As hypothesized, daily hassles, depressive symptoms, and hopelessness were each significantly and positively associated with suicidal ideation. Moreover, the relation between daily hassles and suicidal ideation was, in part, accounted for by depressive symptoms and hopelessness. This study demonstrates the importance of assessing for the presence of these risk factors when determining the likelihood that an abused African American woman will consider suicide. The findings further highlight the value of designing and implementing interventions that target the reduction in depressive symptoms and hopelessness in abused African American women exposed to daily hassles to reduce their suicide risk.     

Examining a model of the relation between religiosity and suicidal ideation in a sample of African American and White college students

In this study, a model of certain aspects of religiosity, social support, and depressive symptomatology that would examine how African Americans may be, differentially, protected from suicide was proposed. Intrinsic religiosity was found to be negatively related to depressive symptoms which were positively related to suicide ideation in a sample of 459 college students. Though the model was expected to produce more robust results for African American compared to White students, we did not find this. Further investigation of religiosity and related phenomena (e.g., spirituality) are warranted across age, socioeconomic, and ethnic groups.     

Suicide and African American teenagers: risk factors and coping mechanisms

In this study we investigated whether locus of control, hopelessness, and depression were primary risk factors for suicide ideation and attempts in African American youth, and whether congruency between locus of control and religious coping style reduced suicide risk. The sample consisted of 176 African American high school students (115 females; 61 males). Multiple and logistic regression were used to determine relationships among study variables. Depression was found to mediate the relationship between hopelessness and suicidal behaviors. External locus of control led to greater risk for hopelessness and depression, with a trend in the predicted direction for suicide attempts. Religious coping style alone was not always associated with reduction of risk of suicidal behaviors, yet some evidence suggests that congruency between locus of control and religious coping style reduces risk. Results provide additional support for suicide interventions to target depressive symptoms. Results also highlight the importance of examining the role of culturally salient variables such as fatalism and religious coping style when developing intervention programs for suicide.     

Loneliness,Depressive Symptomatology,and Suicide Ideation in Adolescence: Cross-Sectional and Longitudinal Analyses

The paper presents the first known longitudinal study of the relationship between loneliness, depressive symptoms, and suicide ideation in adolescence, in a stratified sample of high school students (Time 1 N = 1009; 57 % female; Time 2 N = 541; 60 % female). Cross-lagged structural equation modeling indicated that depressive symptoms led to more loneliness across time, whereas loneliness did not predict higher levels of depressive symptoms across time. Loneliness was found to be a correlate of depressive symptoms at the cross-sectional level, independent of gender, other demographic factors, multiple psychosocial variables, and social desirability. Loneliness did not predict suicide ideation over time or at the cross-sectional level, when controlling for depressive symptoms. Gender did not predict loneliness, depressive symptoms or suicide ideation across time. Future longitudinal studies of the relationship between loneliness, depressive symptoms, and suicide ideation in adolescence should use more extensive designs.     

Suicidal Ideation in Elderly Bereaved: The Role of Complicated Grief

This study examined whether symptoms of complicated grief at baseline predicted suicidal ideation during a depressive episode in elderly bereaved individuals. Over a 17-month period, serial ratings of suicidal ideation, hopelessness, and symptoms of depression, anxiety, and complicated grief were obtained from 130 elderly participants who had lost their spouses within the past 2 years. Groups of active and passive suicidal ideators, as well as nonideator controls, were compared via analysis of variance (ANOVA) with respect to levels of complicated grief, depression, and anxiety. Elderly bereaved with both active and passive suicidal ideation were found to have higher symptomatic levels of depression, hopelessness, complicated grief, and anxiety, as well as lower levels of perceived social support, than nonideators at study entry. Fifty-seven percent of the patients with high complicated grief scores were found to be ideators during the follow-up versus 24% of the patients with low complicated grief scores. Patients with any suicidal ideation had higher symptom levels of depression, anxiety, and complicated grief when they were ideators as compared with periods when they denied ideation. Fifteen out of the 39 ideators had recurrent depressive episodes versus 5 of the 91 nonideators. Patients with a history of suicide attempts were more likely to be ideators after loss than other bereaved. Thus, the condition of having high levels of complicated grief symptoms and depressive symptoms appears to make bereaved individuals vulnerable to suicidal ideation. Detection of high levels of complicated grief could help clinicians identify patients who may be at heightened risk for suicide.     

Positive and Negative Expectations of Hopelessness as Longitudinal Predictors of Depression,Suicidal Ideation,and Suicidal Behavior in High‐Risk Adolescents

The relationship between hopelessness and depression in predicting suicide‐related outcomes varies based on the anticipation of positive versus negative events. In this prospective study of adolescents at elevated risk for suicide, we used two Beck Hopelessness Scale subscales to assess the impact of positive and negative expectations in predicting depression, suicidal ideation, and suicidal behavior over a 2‐ to 4‐year period. In multivariate regressions controlling for depression, suicidal ideation, and negative‐expectation hopelessness, positive‐expectation hopelessness was the only significant predictor of depressive symptoms and suicidal behavior. Clinical interventions may benefit from bolstering positive expectations and building optimism.     

Measures of life stress and social support specific to an Asian student population

We designed two new measures—the Index of Life Stress (ILS) and the Index of Social Support (ISS)—to assist in the prediction of cultural adjustment for an Asian international student population. In the present study, these two measures were administered to 101 Asian international students. Stability estimates over 1 month were high: .97 for the ILS and .81 for the ISS. Construct validity, assessed via factor analyses, and concurrent validity, assessed via regression analyses to criteria of depression, hopelessness, and suicide ideation were satisfactory. Incremental validity for these two measures relative to extant measures of life stress and social support were computed. Results from these analyses indicated that these two measures added incrementally to the prediction of adjustment beyond that offered by existing measures.     

The Role of Body Image and Disordered Eating as Risk Factors for Depression and Suicidal Ideation in Adolescents

There is much empirical literature on factors for adolescent suicide risk, but body image and disordered eating are rarely included in these models. In the current study, disordered eating and body image were examined as risk factors for suicide ideation since these factors are prevalent in adolescence, particularly for females. It was hypothesized that disordered eating and body image, in addition to depressive symptoms, would contribute to suicide ideation. It was also hypothesized that these relationships would be stronger for females than for males. Structural equation modeling was used to test a model of risk for suicide ideation incorporating the above factors in a sample of 392 high school students. Results indicated that disordered eating contributed to both suicide ideation and depressive symptoms, while body image only contributed to depressive symptoms. Depressive symptoms contributed to suicide ideation. The model was found to be cross‐validated with males and females, and no gender differences emerged. Implications of these findings and their importance in constructing future models of adolescent suicide risk are discussed.     

Perceived burdensomeness and suicide ideation in older adults

Older adults have the highest risk of death by suicide in the United States. Improving our understanding of the factors that lead to increased risk of suicide in older adults will greatly inform our ability to prevent suicide in this high-risk group. Two studies were conducted to test the effect of perceived burdensomeness, a component of the interpersonal-psychological theory of suicide (Joiner, 2005), on suicide ideation in older adults. Further, gender was examined as a moderator of this association to determine if perceived burdensomeness exerted a greater influence on suicide ideation in males. The results of these studies suggest that perceived burdensomeness accounts for significant variance in suicide ideation, even after predictors such as depressive symptoms, hopelessness, and functional impairment are controlled. Gender did not moderate the association. The implications of these findings for treatment of older adults with suicide ideation and elevated suicide risk are discussed.     

Concurrent validity of a stress-vulnerability model of suicidal ideation and behavior: a follow-up study

A follow-up study to test the concurrent validity of a stress-vulnerability model of suicidal ideation and behavior was conducted. A total of 202 college students (139 females, 63 males) completed self-report measures of life stress, loneliness, depression, dysfunctional cognitions, reasons for living, hopelessness, current suicide ideation, and predictions of future suicide probability. The results of a multiple-regression analysis indicated that 30% of the variation in suicide ideation scores could be accounted for by the linear combination of negative life stress, depression, loneliness, and few reasons for living. The linear combination of current suicide ideation, hopelessness, dysfunctional cognitions, and few reasons for living explained 56% of the variance in self-predicted future suicide probability. The results are interpreted as being supportive of the proposed model.     

Current suicide proneness and past suicidal behavior in adjudicated adolescents

Youth recently assigned to probation (n = 233) were assessed for current suicide proneness, depression, and hopelessness, as well as for recent suicide ideation, previous suicide ideation, or suicide attempt(s). The Life Attitudes Schedule-Short Form (LAS-SF) was used to assess suicide proneness. As per the LAS-SF, suicide proneness was defined broadly to include current engagement in overtly suicidal behavior as well as in risk-taking and potentially injury-producing behaviors, coupled with a lack of engagement in health and safety behaviors, or self-enhancement behaviors. As expected, current suicide proneness was significantly associated with a history of suicide ideation and attempts, recent ideation, and current depression and hopelessness for adjudicated youth. Gender differences were obtained between the strength of the association between suicide proneness and depressive symptoms. A subgroup of adjudicated youth (n = 39) was then interviewed about their suicidal behaviors. Among other things, these youth indicated that the majority of their previous suicide attempts were committed impulsively.     

Perfectionism,Hopelessness, And Suicide Ideation: Revisions to Diathesis-Stress and Specific Vulnerability Models

The current study examined variables (daily hassles, self-esteem, dispositional optimism, coping modes, and perceived social support) that could potentially moderate associations between dimensions of perfectionism and current feelings of hopelessness and suicide ideation in university students (144 women; 61 men). Our study revealed several significant findings: (1) socially prescribed perfectionism was a significant predictor of suicide ideation, interpersonal hopelessness, and achievement hopelessness for both women and men; (2) self-oriented perfectionism did not have an independent relation with any of the suicide risk outcome variables in either women or men; (3) other-oriented perfectionism was associated negatively with both current hopelessness, particularly interpersonal hopelessness, and suicide ideation in men; (4) the cluster of proposed moderators accounted for additional unique variance in all suicide risk variables in women but in achievement hopelessness only in men; (5) optimism and social hassles were unique predictors but the results varied as a function of gender and outcome; (6) each perfectionism component interacted with specific moderators to enhance or buffer the link between perfectionism and suicide risk. The findings indicate that self-oriented and other-oriented perfectionism are possibly adaptive or maladaptive under certain conditions. Implications for the development of comprehensive, multidimensional, integrated models of the perfectionism–suicide risk link and for prevention and treatment in perfectionists at risk of suicide are discussed.

The problem-solving diathesis in depression,hopelessness, and suicide ideation: A longitudinal analysis

The problem-solving deficit (PSD) diathesis-stress model of suicide behavior proposed by Clum, Patsiokas, and Luscomb (1979) and expanded by Schotte and Clum (1982, 1987) was examined in a short-term longitudinal test. The present study assessed the relationship between problem-solving deficits at Time 1—prior to the stressor (a D or F on a midterm examination)—and adjustment at Time 2—after the Stressor. Evidence was found for an additive predictive relationship for stress and problem-solving deficits to Time 2 measures of depressive symptoms, hopelessness, and suicide ideation. Evidence was also found that PSD × Stress interactions uniquely predicted the three criteria. The results of this study were taken as evidence of problem-solving deficits functioning as a diathesis for depression, hopelessness, and suicide ideation.     

Psychopathology of adolescent suicide: hopelessness, coping beliefs, and depression

Two studies of adolescents examined the relation of several cognitive variables and depression to suicide-related behaviors. Study 1 compared hopelessness and depression in 281 high school students. Unlike research with adults, depression was significantly related to suicidal behaviors, even after hopelessness was statistically controlled. When depression was controlled, hopelessness was unrelated to suicidal behaviors for boys and only modestly related for girls. Study 2 examined depression, hopelessness, survival-coping beliefs, fear of social disapproval, and social desirability in relation to suicidal behaviors in 53 male juvenile delinquents. Again, hopelessness did not account for a significant proportion of the variance in suicide. Depression was uniquely related to past suicide attempts. Survival-coping beliefs were associated with self-predicted future suicide and other suicidal behaviors. Survival-coping beliefs are discussed as a cognitive buffer to suicidal ideation in adolescence.     

An integrative model of suicidal ideation

An integrative path model is presented that details the relationships among several demographic variables, life stress, depression, hopelessness, social support, and suicidal ideation. The sample consisted of 737 university students, 287 males and 450 females. Negative life stress was found to be a significant predictor of both depression and hopelessness, which, in turn, mediated the relationship between life stress and suicidal ideation. Contrary to previous findings, depression proved to be a better predictor of suicidal ideation than hopelessness. Findings also illustrated the importance of including social support measures in the model, as significant relationships were discovered between social support and both life stress and suicidal ideation. The model accounted for a total of 34% of the variance in suicidal ideation. Individual findings are interpreted; the ways in which they reflect on previous research, and future efforts, are discussed.     

Grateful individuals are not suicidal: Buffering risks associated with hopelessness and depressive symptoms

With suicidal behavior serving as a leading cause of injury and death around the world, researchers must expand ongoing efforts to uncover protective factors. In this study, we examined if gratitude mitigated existing risk factors for suicide. Specifically, we predicted that gratitude moderates the relationship between suicidal ideation and (a) hopelessness and (b) depressive symptoms in a sample of 369 diverse undergraduate students. Results indicate that for people who are highly grateful, both hopelessness and depressive symptoms are less likely to be associated with thoughts and intentions to kill oneself. The findings demonstrate the value of integrating protective factors against suicidality, including character strengths such as gratitude, into existing theories that tend to be limited to vulnerability factors. We offer tentative ideas for enhancing the impact of suicide prevention and intervention programs by directly addressing gratitude, which has been shown to be highly modifiable.
