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.     

A Longitudinal Investigation of Depression,Hopelessness, Social Support,and Major and Minor Life Events and Their Relation to Suicidal Ideation in Adolescents

The longitudinal relationship of psychological and social-environmental factors with adolescent suicidal ideation over a 1-year-period was examined in a sample of 374 high school students. Students were assessed twice over a 1-year period with measures of depression, hopelessness, major negative life events, daily hassles, social support, and suicidal ideation. At the initial assessment, daily hassles and negative life events for males and social support and depression for females were significant factors related to suicidal ideation levels 1 year later. Changes in depression and hopelessness were significantly related to changes in suicidal ideation over the 1 year interval for males and females. Differences found between males and females in the relationship of psychological and social-environmental variables with suicidal ideation supports the need to examine gender specific relationships when conducting research on suicidal behavior in adolescents.     

Acculturative stress, depression, and suicidal ideation in Mexican immigrants

This study examined the relationship among acculturative stress, depression, and suicidal ideation in a sample of Mexican immigrants. Also examined were variables that predict depression and suicidal ideation. Multiple regression analyses revealed that acculturative stress significantly predicted depression and suicidal ideation and that family support, social support, religiosity, agreement with the decision to migrate, and expectations for the future were significant predictors of depression and suicidal ideation. The overall findings suggest that adult Mexican immigrants who experience elevated levels of acculturative stress may be at risk for experiencing critical levels of depression and suicidal ideation. The findings highlight the importance of using culturally relevant clinical methods when assessing and treating the depressed and potentially suicidal acculturating individual.     

Self-Esteem and Social Support as Moderators of Depression,Body Image,and Disordered Eating for Suicidal Ideation in Adolescents

The current study investigated risk factors for suicidal ideation in a community sample of 392 adolescents (males 51.9 %; females 48.1 %), while also evaluating self-esteem, perceived parent support, and perceived peer support as protective factors and potential moderators between suicidal ideation and the 3 risk factors. Disordered eating, depression, parent support, and peer support were found to be significant predictors of current suicidal ideation, but body satisfaction was not. The relationship between depression and suicidal ideation was significantly moderated by both self-esteem and parent support, while the relationship between disordered eating and suicidal ideation was significantly moderated by peer support. Results underscore the importance of examining protective factors for suicide risk, as they have the potential to reduce suicidal ideation in adolescents.     

The buffering role of social support on the associations among discrimination,mental health,and suicidality in a transgender sample

Introduction: Per the minority stress framework, trans individuals often experience psychological distress given the unique stress engendered by gender identity–related discrimination. Prior research has identified social support as particularly important for psychological distress and has suggested that social support may moderate this relationship. The purpose of the current study was to explore the patterns of connections among discrimination, mental health, and suicidal ideation in trans individuals and whether social support moderates these relationships. Methods: Participants (N = 78) completed measures of these constructs as part of a national online survey. Results: A series of simultaneous multiple regressions found that harassment/rejection discrimination was a unique positive predictor of mental health symptoms and suicidal ideation, with depression positively predicting suicidal ideation. A mediational model indicated that the association between harassment/rejection discrimination and suicidal ideation was fully mediated by depression. Three moderated meditational models were run, and one yielded a significant interaction, such that discrimination predicted suicidal ideation most strongly when participants had low social support from a significant other in comparison to participants who had moderate or high support. Further, conditional direct effects identified that discrimination led to ideation only for individuals with low support from friends or a significant other but not for those with moderate or high support. Conclusions: Helping trans individuals cope with harassment and rejection, particularly by drawing on social support, may promote better mental health, which could help reduce suicidality in this population.     

Acculturative stress, depression, and suicidal ideation among Central American immigrants

No previous studies have examined suicide risk among Central American immigrants. The present study explored the relationship between acculturative stress, depression, and suicidal ideation among Central American immigrants. Also examined were variables that predict depression and suicidal ideation. Elevated levels of acculturative stress were significantly correlated with high levels of depression and suicidal ideation. Family dysfunction, ineffective social support, nonpositive expectations concerning the future, low levels of religiosity, low levels of education and income, and lack of agreement with the decision to immigrate were significantly associated with high levels of depression and suicidal ideation. The overall findings suggest that Central American immigrants who experience elevated levels of acculturative stress may be at risk for experiencing heightened levels of depression and suicidal ideation. The findings highlight the importance of using culturally relevant clinical methods when assessing and treating depressed and potentially suicidal acculturating individuals.     

Social Anxiety Symptoms and Suicidal Ideation in a Clinical Sample of Early Adolescents: Examining Loneliness and Social Support as Longitudinal Mediators

Recent research has shown that social anxiety may be related to increased risk for suicidal ideation in teens, although this research largely has been cross-sectional and has not examined potential mediators of this relationship. A clinical sample of 144 early adolescents (72 % female; 12–15 years old) was assessed during psychiatric inpatient hospitalization and followed up at 9 and 18 months post-baseline. Symptoms of social anxiety, depression, suicidal ideation, loneliness, and perceived social support were assessed via structured interviews and self-report instruments. Structural equation modeling revealed a significant direct relationship between social anxiety symptoms at baseline and suicidal ideation at 18 months post-baseline, even after controlling for baseline depressive symptoms and ideation. A second multiple mediation model revealed that baseline social anxiety had a significant indirect effect on suicidal ideation at 18 months post-baseline through loneliness at 9 months post-baseline. Social anxiety did not have a significant indirect effect on suicidal ideation through perceived social support from either parents or close friends. Findings suggest that loneliness may be particularly implicated in the relationship between social anxiety and suicidality in teens. Clinicians should assess and address feelings of loneliness when treating socially anxious adolescents.     

Social-Cognitive Moderators of the Relationship between Peer Victimization and Suicidal Ideation among Psychiatrically Hospitalized Adolescents

Peer victimization among children and adolescents is a major public health concern, given its widespread individual and societal ramifications. Victims of peer aggression often face significant levels of psychological distress and social difficulties, such as depression, suicidal ideation, suicide attempts, and social rejection. The purpose of this study was to examine whether cognitive distortions and perceptions of social support moderate the association between peer victimization and suicidal thoughts among psychiatrically hospitalized adolescents. Participants included 183 psychiatrically hospitalized adolescents (ages 13 to 18). In multiple regression analyses that controlled for gender, social and cognitive factors served as significant resource factors. Cognitive factors also moderated the relationship between peer victimization and suicidal ideation.     

问题性网络使用对初中生自杀意念的影响:一个有调节的中介模型

采用戴维斯在线认知量表、自杀意念自评量表、UCLA孤独感量表以及领悟社会支持量表，对江西赣州九所公立学校三个年级的1311名初中生进行测查，探讨问题性网络使用对初中生自杀意念的影响及作用机制。结果发现：（1）问题性网络使用对初中生的孤独感和自杀意念都有显著的正向预测作用；（2）孤独感在问题性网络使用与初中生自杀意念之间起着部分中介作用；（3）孤独感和自杀意念的关系（中介效应的后半段路径）受到领悟社会支持的调节，即孤独感对自杀意念的影响随着领悟社会支持的增强而减弱。因此，问题性网络使用和初中生自杀意念之间存在孤独感的中介作用和领悟社会支持的调节作用。     

Peer functioning, family dysfunction, and psychological symptoms in a risk factor model for adolescent inpatients' suicidal ideation severity

Examined models of suicidal ideation severity that include two psychosocial risk factors (i.e., peer and family functioning) and four domains of psychological symptoms (i.e., generalized anxiety, depression, conduct problems, and substance abuse/dependence). Participants were 96 psychiatric inpatients (32 boys, 64 girls), ages 12 to 17, who were hospitalized because of concerns of suicidality. Adolescents completed a structured diagnostic interview, measures of suicidal ideation, and several dimensions of family and peer functioning. Results supported a model in which greater levels of perceived peer rejection and lower levels of close friendship support were associated directly with more severe suicidal ideation. In addition, indirect pathways included deviant peer affiliation and global family dysfunction related to suicidal ideation via substance use and depression symptoms. The results are among the first to demonstrate relations between suicidal ideation and several areas of adolescent peer functioning, as well as divergent processes for peer and family predictors of suicidal ideation.     

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.     

Relations Between Suicidal Ideation,Depression, and Emotional Autonomy from Parents in Adolescence

We examined the relations between depression, emotional autonomy quality-related constructs of separation and detachment, and suicidal ideation, focusing on the unique and common contribution that depression, separation and detachment made to suicidal ideation. We also examined gender differences. 403 adolescents, 196 boys and 207 girls, completed self-report measures of depression, separation and detachment, and suicidal ideation. The data showed a significant relation between depression and suicidal ideation both for boys and girls, and between detachment and suicidal ideation only for boys. Results for boys supported an additive model such that depression and detachment each contributed unique variance to boys’ suicidal ideation, and an interactive model such that detachment contributed to exacerbate the risk of suicidal ideation when boys were already at risk because of depression. The data for girls supported an interactive, but not additive, model such that depression and detachment did not contribute independently to girls’ suicidal ideation but in a joint way.     

Family support,family stress,and suicidal ideation in a combat-exposed sample of Operation Enduring Freedom/Operation Iraqi Freedom veterans

Background and Objectives: Deployment-related risk factors for suicidal ideation among Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans have received a great deal of attention. Studies show that mental health symptoms mediate the association between most deployment stressors and suicidal ideation; however, family-related factors during deployment are largely unexplored. We examined posttraumatic stress disorder (PTSD) and depression symptoms as mediators of the associations between deployment family support and stress and post-deployment suicidal ideation in combat-exposed OEF/OIF veterans. Design: National cross-sectional mail survey. Methods: 1046 veterans responded to the survey. The sample for this study was 978 veterans who experienced combat. Regression-based path analyses were conducted. Results: Family support and stress had direct associations with suicidal ideation. When PTSD and depression symptoms were examined as mediators of these associations, results revealed significant indirect paths through these symptoms. Conclusions: This study contributes to the literature on suicidal ideation risk factors among OEF/OIF veterans. Deployment family support and family stress are associated with suicidal ideation; however these associations occur primarily through mental health symptomatology, consistent with findings observed for other deployment factors. This research supports ongoing efforts to treat mental health symptomatology as a means of suicide prevention.     

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.     

The Interplay Among Risk Factors for Suicidal Ideation and Suicide: The Role of Depression, Poor Health, and Loved Ones' Messages of Support and Criticism

When individuals who receive social support are in poor physical or mental health and are criticized or made to feel unwanted, they may perceive themselves as a burden. Poor physical health and depression were hypothesized to exacerbate the harmful effects on suicidal ideation of receiving critical negative messages and of receiving social support. These hypotheses were tested using secondary analyses of data from a sample of 533 unemployed married individuals who were assessed shortly after job loss, and 6 months later. The results of our analyses supported the hypotheses and demonstrated that for participants with poor health or high level of depressive symptoms an increase in critical messages and social support (from Time 1 to Time 2) predicted increased suicidal ideation. This relationship was not observed for non- depressed participants in good health. The results are discussed in terms of their implications for suicide prevention.     

The relationships among gratitude,self‐esteem,depression, and suicidal ideation among undergraduate students

The main purpose of this study was to examine the relationships among gratitude, self‐esteem, depression, and suicidal ideation. In total, 814 undergraduate participants (259 males and 555 females with mean age of 20.13 years) completed four inventories measuring the variables of interest. Analyses of structural equation modeling found that gratitude had direct effects on individuals' self‐esteem, depression, and suicidal ideation. In addition, gratitude had indirect effects on individuals' suicidal ideation via self‐esteem and depression, and self‐esteem had direct effects on individuals' depression. These results support the proposed model of suicidal ideation and contribute to the understanding of how gratitude influences individuals' suicidal ideation via psychological and physical variables.     

Health-risk behaviors and suicidal ideation: a preliminary study of cognitive and developmental factors

Various theorists have suggested that unhealthy behaviors such as cigarette smoking and problem drinking may be subtle forms of suicidality. Consistent with this view, prior research has shown an association between health risk behaviors and suicidal ideation. In the present study we examined relationships among suicidal ideation, health-related attitudes and behaviors, and adverse childhood events. We hypothesized that unhealthy attitudes, perhaps shaped by adverse childhood events, would help explain the association between suicidal phenomena and unhealthy behaviors. Three-hundred eighteen college students completed surveys covering health risk behaviors, depression, suicidal ideation, and health-related attitudes. Results supported the hypothesized associations among these variables. However, contrary to our hypotheses, the association between suicidal ideation and health-compromising behaviors was limited largely to substance-related behaviors. Moreover, the association between suicidal ideation and health-related attitudes was mediated by depression. Adverse childhood events were associated with health-related attitudes, but this relationship was mediated by depression. These results are less suggestive of the notion of unhealthy behaviors as subtle suicidality than a model in which suicidality associates specifically with psychopathological states such as depression and substance abuse. Implications for treatment and prevention programs are discussed.

The Functions of Social Support as Protective Factors for Suicidal Ideation in a Sample of Air Force Personnel

This study examined various functions of social support (i.e., tangible, esteem, belonging, and appraisal) were examined as protective factors for suicidal ideation in a sample of 273 active duty Air Force Security Forces personnel. Generalized linear regression analyses were conducted to determine if various social support functions were differentially associated with the presence and severity of suicidal ideation, both as main effects and as moderators of emotional distress. None of the four social support functions differentiated suicidal from nonsuicidal Airmen, but esteem support (i.e., feeling respected, encouraged, and valued by others) was associated with significantly less severe suicidal ideation (B = ?.074, SE = .025, p = .003). A significant interaction of tangible support (i.e., access to material resources) with emotional distress indicated that emotional distress was associated with more severe suicidal ideation only among Airmen reporting low levels of tangible support (B = .006, SE = .003, p = .018). When considered concurrently, both tangible and self‐esteem functions of social support are differentially associated with decreased suicidal ideation among Airmen, but belonging (i.e., having someone to do things with) and appraisal (i.e., having someone to talk to about problems) functions were not. Findings suggest that different aspects of social support affect suicidal ideation in different ways.     

Connection between Suicidal Ideation,Life Meaning,and Leisure Time Activities

This study is an examination of the links between adolescent suicidal ideation, life meaning, and the ways they spend their leisure time. The sample consisted of 450 students aged 15–18. Findings showed a significant negative correlation between suicidal ideation and sense of life meaning, encompassing factors such as age and gender. Adolescents with involvement in social activities demonstrated lower levels of suicidal ideation (total score), and lower levels of depression and anxiety, than the other two groups. The study discusses the research and practical implications of these findings. The findings suggest the possibility of establishing prevention, intervention, and therapy programs for adolescents based on life meaning.
