Suicidal ideation and suicidal attempts in a population-based study of Chinese people: risk attributable to hopelessness, depression, and social factors

BACKGROUND: The population attributable fraction of hopelessness, depression and other risk factors for suicidal ideation and suicidal attempts in Asian population is unknown. Social support is often said to be a buffer against the effect of hopelessness and depression. METHODS: Suicidal ideation, suicidal attempts as well as demographic and psychometric data were delineated in a random and representative population sample of 2,219 Chinese people in Hong Kong. The population attributable fraction was used to determine the contribution of hopelessness, depression and other risk factors to suicidal ideation and attempts. RESULTS: Multivariate modelling shows that about 40% of suicidal ideation and attempts was attributable to depression and about 20% was attributable to hopelessness. Drug abuse and marital dissolution were also significant contributors to suicidality. The impact of hopelessness and depression was not affected by social support. LIMITATIONS: Suicidality was self-reported. CONCLUSIONS: Suicidal ideation and suicidal attempts were to a large extent attributable to depression and hopelessness, and, to a lesser extent, drug abuse and marital dissolution. Social support appeared to play little role as a buffer.     

Prevalence and correlates of suicidal ideation during pregnancy

Data are scarce regarding the prevalence and risk factors for antenatal suicidal ideation because systematic screening for suicidal ideation during pregnancy is rare. This study reports the prevalence and correlates of suicidal ideation during pregnancy. We performed cross-sectional analysis of data from an ongoing registry. Study participants were 2,159 women receiving prenatal care at a university obstetric clinic from January 2004 through March 2010. Multiple logistic regression identified factors associated with antenatal suicidal ideation as measured by the Patient Health Questionnaire. Overall, 2.7% of the sample reported antenatal suicidal ideation. Over 50% of women who reported antenatal suicidal ideation also reported major depression. In the fully adjusted model antenatal major depression (OR = 11.50; 95% CI 5.40, 24.48) and antenatal psychosocial stress (OR = 3.19; 95% CI 1.44, 7.05) were positively associated with an increased risk of antenatal suicidal ideation. We found that being non-Hispanic White was associated with a decreased risk of antenatal suicidal ideation (OR = 0.51; 95% CI 0.26–0.99). The prevalence of antenatal suicidal ideation in the present study was similar to rates reported in nationally representative non-pregnant samples. In other words, pregnancy is not a protective factor against suicidal ideation. Given the high comorbidity of antenatal suicidal ideation with major depression, efforts should be made to identify those women at risk for antenatal suicidal ideation through universal screening.     

Why do some cancer patients with depression desire an early death and others do not?

Major depression is a well-documented risk factor for suicide in cancer patients as well as in the general population. However, there are no data explaining why some cancer patients suffering from major depression have suicidal ideation, while others do not. The authors investigated the background differences among cancer patients suffering from major depression with and without suicidal ideation by analyzing the consultation data of patients referred to the psychiatry division. Among the 1,721 referred patients, 220 (12.8%) were diagnosed with major depression, and of these 113 (51.4%) had suicidal ideation. Logistic regression analysis indicated that poor physical functioning and severe depression were significant risk factors. These preliminary findings suggest that the severity of major depression and physical functioning are important indicators of suicidal ideation among cancer patients.     

Self-perception of poor health and suicidal ideation in medical patients

OBJECTIVE: To determine the relationship between self-perceived health and suicidal ideation among patients in general internal medicine practice settings. METHOD: A representative sample of 4007 patients was assessed for current suicidal ideation, self-perception of health, current medical disorders and current mental disorders (major depression, generalized anxiety disorder, panic attacks and alcohol use disorder) with the PRIME-MD Patient Health Questionnaire. RESULTS: Patients with self-perception of poor health, compared with those who reported more favourable health perception, were significantly more likely to report current suicidal ideation (35.2% v. 8.3%; chi2 = 97.4, df = 1, P < 0.0001). Multivariate logistic regression analyses revealed that the perception of poor health was associated with a significantly increased risk of suicidal ideation (OR = 3.1, CI 1.9, 5.0), even after adjusting for sociodemographic characteristics, mental disorders and common physical illnesses. CONCLUSION: Self-perception of poor health is associated with a significantly increased risk of suicidal ideation among general medical patients, even in the absence of common mental and physical disorders. These findings add to a growing literature on the importance of self-perceived health in the treatment and outcomes of mental and physical well-being by documenting self-perceived poor health as a risk factor for suicidal ideation in medical patients.     

Risk factors for suicidality in Europe: results from the ESEMED study

BACKGROUND: Precise knowledge of the epidemiology of suicidality provides necessary information for designing prevention programs. The aims of the present study were to investigate the prevalence and correlates of suicidal ideas and attempts in the general population of Europe. METHODS: The European Study on the Epidemiology of Mental Disorders (ESEMED) is a cross-sectional household survey carried out in a probability representative sample of non-institutionalised adults (aged 18 years or older) of six European countries (Belgium, France, Germany, Italy, the Netherlands and Spain). The Composite International Diagnostic Interview (CIDI 3.0) was administered to 21,425 individuals. RESULTS: Lifetime prevalence of suicidal ideation was 7.8% and of suicidal attempts 1.3%. Being women, younger and divorced or widowed were associated with a higher prevalence of suicide ideation and attempts. Psychiatric diagnoses were strongly related to suicidality. Among them, major depressive episode (Rate ratio 2.9 for lifetime ideas and 4.8 for lifetime attempts), dysthymia (RR 2.0 and 1.6), GAD (RR 1.8 and 2.3 for lifetime), PTSD (RR 1.9 and 2.0) and alcohol dependence (RR 1.7 and 2.5) were the most important. Population attributable risks for lifetime suicidal attempt was 28% for major depression. LIMITATIONS: Information about suicidal ideas and attempts was self reported, psychiatric diagnoses were made using fully structured lay interviews rather than clinician-administered interviews. CONCLUSIONS: In spite of meaningful country variation in prevalence, risk factors for suicidality are consistent in the European countries. Population prevention programmes should focus on early diagnosis and treatment of major depression and alcohol abuse and in those individuals with recent appearance of suicidal ideas.     

Suicidal ideation among patients with acute life-threatening physical illness: patients with stroke, traumatic brain injury, myocardial infarction, and spinal cord injury.

Suicide is one of the leading causes of death in the community. The risk of suicide is greater among patients with physical illnesses than among the general population. This study was undertaken to evaluate the clinical characteristics and correlates of suicidal ideation in patients with acute life-threatening physical illnesses and to assess the duration of suicidal ideation. The study included a consecutive series of patients admitted with stroke, traumatic brain injury, myocardial infarction, or spinal cord injury (n=496). Study participants were administered a semistructured psychiatric interview as well as a series of standardized quantitative scales of mood, cognitive function, physical impairment, social ties, and social functioning. Follow-up evaluations of up to 24 months were also carried out. This study found that 36 (7.3%) patients with acute medical illness had clinically significant suicidal ideation. The suicidal ideation occurred mostly among patients with major depression and sometimes in those with minor depression. About 25% of patients with major depression and acute physical illnesses developed suicidal ideation. After the improvement of depressive disorders, suicidal ideations were ameliorated. These findings suggest that the detection and treatment of depressive disorders is the most important factor in preventing suicide among this patient population.     

Anxiety disorders and suicidal behaviours in adolescence and young adulthood: findings from a longitudinal study

BACKGROUND: The aim of this study was to estimate the extent to which anxiety disorders contribute to an increase in suicidal behaviour after controlling for both observed and non-observed sources of confounding. METHOD: Data were collected from the Christchurch Health and Development Study (CHDS), a 25-year longitudinal study of over 1000 participants. Measures of anxiety disorders [phobia, generalized anxiety disorder (GAD), panic disorder], major depression (MD), substance use disorders, conduct/antisocial personality disorder, stressful life events, unemployment, and suicidal ideation/attempts for subjects aged 16-18, 18-21 and 21-25 years were used to fit random and fixed effects regression models of the associations between anxiety disorders and suicidal behaviours. RESULTS: Anxiety disorders were strongly associated with suicidal ideation/attempts. Any single anxiety disorder increased the odds of suicidal ideation by 7.96 times [95% confidence interval (CI) 5.69-11.13] and increased the rate of suicide attempts by 5.85 times (95% CI 3.66-9.32). Control for co-occurring mental disorders, non-observed fixed confounding factors and life stress reduced these associations [suicidal ideation odds ratio (OR) 2.80, 95% CI 1.71-4.58; suicide attempts incidence rate ratio (IRR) 1.90, 95% CI 1.07-3.39]. Rates of suicidal behaviour also increased with the number of anxiety disorders. Estimates of the population attributable risk suggested that anxiety disorders accounted for 7-10% of the suicidality in the cohort. CONCLUSIONS: Anxiety disorders may be a risk factor for suicidality, even after controlling for confounding, with risks increasing with multiple anxiety disorders. Management of anxiety disorders may be an important component in strategies to reduce population rates of suicide.     

How Is the Suicide Ideation in the Korean Armed Forces Affected by Mental Illness,Traumatic Events,and Social Support?

BackgroundSuicide is one of the leading causes of death in the military as in the general population. To mitigate such a serious public health problem, identifying the risk or protective factors of suicide behaviors is crucial.MethodsWe analyzed the representative data of the 2014 Korean Armed Forces to explore the relationship between past year adverse events (PAE), accumulated lifetime trauma (ALT), mental illness vulnerability, perceived social support, and suicidal ideation in the previous year.ResultsAmong the 6,377 subjects, 3.7% of males and 6.2% of females reported suicidal ideation in the previous year. Multivariate analytic models identified significant associations of PAE and ALT with suicidal ideation with a dose-response pattern. The mental illness vulnerability showed the most significant association with suicidal ideation even after controlling PAE or ALT. We found that perceived social support may be potentially linked with a reduced risk of suicidal ideation.ConclusionThis Korean military representative data demonstrates mental illness vulnerability; PAE; and lifetime trauma as significant risk factors of suicidal ideation, while perceived social support was found as a potential protective factor. Given the importance of the prevention of suicide in the military, those risk and protective factors may be used to screen soldiers at risk of suicide and provide further support on mental health services as needed.     

Diagnostic outcome of adolescent self-reported suicidal ideation at 8-year follow-up

BACKGROUND: There are few epidemiological data on the outcome of adolescent self-reported suicidal ideation. METHOD: Data from an epidemiological study were used to examine self-reported suicidal ideation in adolescence as a predictor of suicidal ideation and psychiatric diagnoses at 8-year follow-up. RESULTS: Suicidal ideation was reported by 41 (4.5%) of 912 adolescents aged 11-18 and by 19 (2.5%) of 795 young adults aged 19-26. Most parents of adolescents with positive self-report did not report suicidal ideation in their child. Suicidal ideation in adolescents and young adults was associated with other psychiatric problems. Adolescent self-reported suicidal ideation was not a predictor of suicidal ideation or any major psychiatric disorder 8 years later. In males, suicidal ideation in adolescence was associated with specific phobia at follow-up. LIMITATIONS: The sample of adolescents may not be representative of the general population. There were no outcome measures other than DSM-IV diagnoses. Suicidal ideation was assessed by only one item, both at baseline and follow-up. CONCLUSIONS: Adolescents and young adults with self-reported suicidal ideation had high rates of psychiatric problems. Adolescent self-reported suicidal ideation did not predict suicidal ideation or any major psychiatric disorders (i.e. depressive disorders, substance use disorders, or psychotic disorders) at follow-up.     

BDNF promoter methylation and suicidal behavior in depressive patients

Introduction

Suicide is a major health problem, and depression is a major psychiatric cause of suicide. Suicide is influenced by the multifactorial interaction of many risk factors. Therefore, epigenetic research may lead to understandings that are applicable to suicide. This study investigated whether epigenetic changes are associated with suicidal behavior and evaluated the treatment outcome of suicidal ideation in depressive patients.

Methods

In 108 patients with major depression, the promoter methylation of the gene encoding brain-derived neurotrophic factor (BDNF) was measured. Sociodemographic and clinical characteristics including a history of previous depressive episodes, age at onset, duration of illnesses, family history of depression, and number of stressful life events as well as subjective perception of stress and assessment scales for depression (HAMD), anxiety (HAMA), function (SOFAS), disability (WHODAS-12), and quality of life (WHOQOL-BREF) were evaluated at baseline. Suicidal behavior was ascertained using a semistructured clinical interview with questions about severity and intent. Beck Scale for Suicide Ideation (BSS) was administered during 12 weeks of treatment with antidepressants.

Results

A higher BDNF promoter methylation status was significantly associated with a previous suicidal attempt history, suicidal ideation during treatment, and suicidal ideation at last evaluation as well as with higher BSS scores and poor treatment outcomes for suicidal ideation.

Limitations

Methylation status was investigated with limited area of the BDNF gene and sample size was relatively small.

Conclusions

BDNF methylation status could be a proxy marker for previous suicidal attempts and a clinical biomarker for poor treatment outcomes of suicidal ideation in depression.     

Clinical correlates of anxious depression among elderly patients with depression

OBJECTIVE: The purpose of this study was to determine the clinical correlates of comorbid anxiety and depression in a sample of older patients with major depression. METHODS: 352 patients aged 59 and older with major depression were enrolled in the Study of Depression in Later Life at Duke University, of whom 148 met criteria for lifetime generalized anxiety disorder. Participants completed self-report assessments of performance in basic and instrumental activities of daily living, social support, suicidal ideation, life satisfaction, and stressful life events. Cognitive assessment was done with the Mini-Mental State Examination. RESULTS: The prevalence of lifetime anxiety in our depressed sample was 42%. Patients with anxious depression were significantly younger, and had greater suicidal ideation, more impairment of subjective social support, and more severe depressive symptoms. CONCLUSION: In elderly patients with anxious depression, psychosocial support and suicidal ideation should be assessed. Whether improvement of subjective social support leads to reduction in anxious depression should be investigated.     

Suicidal behaviour in adolescence and subsequent mental health outcomes in young adulthood

BACKGROUND: The aim of this study was to examine the linkages between suicidal ideation and attempt in adolescence and subsequent suicidal behaviours and mental health in young adulthood. METHOD: Data were gathered during the course of a 25-year longitudinal study of a birth cohort of 1265 New Zealand children. The information collected included: (a) measures of suicidal thoughts and attempts in adolescence (< 18 years); (b) measures of suicidal ideation, suicide attempt, major depression, anxiety disorders, and substance use disorders in young adulthood (18-25 years); and (c) measures of childhood and family background, individual characteristics, and mental disorders in adolescence. RESULTS: After statistical adjustment for confounding factors, suicide attempt in adolescence was associated with increased risks of subsequent suicidal ideation (OR 5.7) suicide attempt (OR 17.8) and major depression (OR 1.5). Those reporting suicidal ideation without suicide attempt showed moderate increases in risks of later suicidal ideation (OR 2.5), suicide attempt (OR 2.0) and major depression (OR 1.6). In addition, there was evidence of an interactive relationship in which suicidal behaviour in adolescence was associated with increased risks of later substance use disorders in females but not males. CONCLUSIONS: Young people reporting suicidal ideation or making a suicide attempt are an at-risk population for subsequent suicidal behaviour and depression. Further research is needed into the reasons for suicidal adolescent females being at greater risk of later substance use disorder.     

Childhood bullying as a risk for later depression and suicidal ideation among Finnish males

BACKGROUND: Little is known about the predictive association between childhood bullying behavior with depression and suicidal ideation at age 18. METHODS: The sample included 2348 boys born in 1981. Information about bullying was gathered at the age of 8 from self, parent and teacher's reports. Depression and suicidal ideation were assessed during the Finnish military call-up examination. RESULTS: Based on regression models, boys who were bullies frequently, but not merely sometimes, were more likely to be severely depressed and to report suicidal ideation compared to boys who were not bullies. When controlling for depression at age 8 the association between frequent bullying and severe depression was maintained but the association with suicidal ideation became non-significant. Boys who were only victimized were not more likely to be depressed or to report suicidal ideation at age 18. Boys who were frequently both bullies and victims were found to be at risk for later depression. LIMITATIONS: Our finding can only be generalized to boys who were involved in bullying at elementary school age. Data at age 18 was based only on self-reports and the bullying/victimization questions were very general. CONCLUSIONS: Childhood bullying behavior is a risk factor for later depression. Screening and intervention for bullying behavior in the early school years is recommended to avoid subsequent internalizing problem in late adolescence.     

Suicidal ideation in pregnancy: an epidemiologic review

Suicidal behaviors are the leading causes of injury and death worldwide, and are leading causes of maternal deaths in some countries. One of the strongest risk factors, suicidal ideation, is considered a harbinger and distal predictor of later suicide attempt and completion, and also presents an opportunity for interventions prior to physical self-harm. The purpose of this systematic epidemiologic review is to synthesize available research on antepartum suicidal ideation. Original publications were identified through searches of the electronic databases using the search terms pregnancy, pregnant women, suicidal ideation, and pregnan* and suicid* as root searches. We also reviewed references of published articles. We identified a total of 2626 articles through the electronic database search. After irrelevant and redundant articles were excluded, 57 articles were selected. The selected articles were original articles that focused on pregnancy and suicidal ideation. Of the 57 included articles, 20 reported prevalence, 26 reported risk factors, 21 reported consequences of antepartum suicidal ideation, and 5 reported on screening measures. Available evidence indicates that pregnant women are more likely than the general population to endorse suicidal ideation. Additionally, a number of risk factors for antepartum suicidal ideation were identified including intimate partner violence, <12-year education, and major depressive disorder. There is a need for enhanced screening for antepartum suicidal ideation. The few screening instruments that exist are limited as they were primarily developed to measure antepartum and postpartum depression. Given a substantial proportion of women with suicidal ideation that does not meet clinical thresholds of depression and given the stress–diathesis model that shows susceptibility to suicidal behavior independent of depressive disorders, innovative approaches to improve screening and detection of antepartum suicidal ideation are urgently needed.     

Psychosocial factors associated with suicidal ideation in clinical patients with depression

Background

Depression is a major risk factor for suicide, but few studies have examined psychosocial risk factors for suicide in clinical patients with depression. The purpose of this study was to investigate psychosocial factors which could be associated with suicidal ideation in clinical patients with depression including: sick-leave, help-seeking behavior, and reluctance to admit mental health problems.

Methods

A multi-center cross-sectional survey using self-report questionnaire was conducted at 54 outpatient psychiatric clinics in Tokyo in 2012. Adult outpatients who were diagnosed by psychiatrists as mood disorders (F30–F39) in the International Classification of Diseases-10 (ICD-10) were included in the study. Those who met the criteria for current hypomanic or manic episode were excluded from the study.

Results

A total of 189 patients with depression participated in the survey. Multivariable logistic regression analysis showed that taking sick-leave and having sought help from family were associated with decreased odds of current suicidal ideation. Moderate or more severe depression was associated with increased odds of suicidal ideation, and reluctance to admit own mental health problem tended to increase odds of suicidal ideation.

Limitations

Living status and suicidal ideation before consultation with psychiatrist were not investigated. Severity of suicidal ideation and comorbid psychiatric disorders were not assessed.

Conclusions

Importance of treatment of more severe depression for suicide prevention was confirmed. Industrial health staffs should consider the possibility of positive effect of taking sick-leave when they see employees with depression. Promoting help-seeking for family and reducing stigma of mental illness may be effective for suicide prevention.     

Depression and suicidal ideation in patients who discontinue the life-support treatment of dialysis

OBJECTIVE: The objective of this study was to determine the prevalence of major depression and suicidal ideation in patients who stop the life-support treatment of dialysis. METHODS: The authors prospectively studied 79 subjects who discontinued maintenance dialysis at eight facilities in North America. Structured interviews were conducted with 23 patients and 76 families. RESULTS: The prevalence of major depression in the sample was between 5% and 25%, and only 1 of 22 patients considered himself to have the illness of depression. Approximately 12% of the respondents were unsure or believed that discontinuing dialysis was the equivalent of suicide. This belief did not correlate with measures of depression. In comparison with the general population there seemed to be an increased prevalence of past suicide attempts. CONCLUSIONS: Most patients who decide to stop dialysis do not seem to be influenced by major depression or ordinary suicidal ideation. Although the sample size was small, these results highlight the need to further examine the theoretical framework and terminology of depression and suicide in the context of terminal illness.     

Fluoxetine: no association with suicidality in obsessive-compulsive disorder.

Since (a) obsessive-compulsive disorder (OCD) may involve serotonergic neural transmission abnormalities also though to be related to regulation of suicide and aggression, (b) comorbidity between OCD and depression is substantial, and (c) depression is a major risk factor for suicide, a comprehensive analysis of clinical trial data was undertaken to assess the potential association of fluoxetine, a serotonin uptake inhibitor, and suicidality (suicidal acts and ideation). Pooled data from clinical trials comparing fluoxetine (n = 266) and placebo (n = 89) in patients with DSM-IIIR OCD were analyzed retrospectively. No suicidal acts occurred during placebo lead-in or double-blind therapy. Mean Hamilton Depression Scale item 3 (suicide item) scores improved statistically significantly with fluoxetine compared with placebo. Worsening in suicidal ideation was statistically significantly more frequent with placebo than with fluoxetine. Emergence of substantial suicidal ideation (change in baseline item 3 score of 0 or 1 to 3 or 4) was numerically greater with placebo than with fluoxetine (3.6% vs. 1.7%; not statistically significant). The incidence of suicidality in fluoxetine-treated patients with OCD was low, compared favorably with rates in corresponding placebo-treated patients, and was well within the range of estimates in previous studies of patients with OCD. These controlled clinical trial results suggest no undue risk of suicidality in patients with OCD treated with fluoxetine.     

Recurrence of suicidal ideation across depressive episodes

BACKGROUND: In recent years it has become clear that depression is a recurrent disorder, with the risk of recurrence in those with two or more episodes being as high as 90%. This has prompted interest in the consistency of individual depressive symptoms across consecutive episodes, an issue that is important for symptoms such as suicidal ideation, where a past history may give important indicators of future behaviour. METHODS: We prospectively examined 69 individuals with a history of Major Depression, over 12 months, 38 of whom experienced a recurrence of major depression during the follow-up period. RESULTS: Spearman's rank order correlations between severity ratings of each symptom of major depression during a previous episode and severity ratings at recurrence showed significant associations for suicidality, guilt or worthlessness and thinking difficulties only. Weighted kappa coefficients indicated relatively low levels of agreement across episodes for most diagnostic symptoms, with suicidality showing the strongest relationship. Using a broad definition of suicidality-- any reporting of thoughts of death or suicide during episode-- a much higher level of agreement (kappa = .64) was found, with 83% of individuals falling into the same category (suicidal/non-suicidal) at both episodes. LIMITATIONS: This study was based on a relatively small sample and examines re-emergence of suicidal ideation in the absence of suicidal behaviour. CONCLUSIONS: This study provides preliminary evidence of cross-episode consistency in the recurrence of suicidal ideation, in line with the differential activation theory of suicidality in depression.     

A prospective study of thoughts of self-harm and suicidal ideation during the postpartum period in women with mood disorders

Individuals with mood disorders are at higher risk for self-harm and suicidal ideation than other psychiatric group. However, the risk of self-harm and suicidal ideation after pregnancy for women with mood disorders is unknown. This investigation assessed the prevalence of thoughts of self-harm and suicidal ideation during the 1-year postpartum period in women with major depressive disorder or bipolar II disorder. Data were collected between June 2005 and March 2010 from a convenience sample of women participating in a study on the course of mood disorders during pregnancy and postpartum. Participant diagnosis was confirmed using the Structured Clinical Interview for DSM-IV. Thoughts of self-harm were assessed using the Edinburgh Postnatal Depression Scale item 10 and suicidal ideation was assessed using the Hamilton Depression Rating Scale item 3. During the 1-year postpartum period, 16.97 % reported thoughts of self-harm while 6.16 % reported suicidal ideation. Further, those reporting thoughts of self-harm or suicidal ideation postpartum also reported higher levels of depression and hypomanic symptoms. We found that a number of women in our sample of women with a diagnosed mood disorder report experiencing thoughts of self-harm and suicidal ideation during the postpartum.     

Personality traits as correlates of suicide attempts and suicidal ideation in young adults

BACKGROUND: Adults in their twenties appear to be at high risk for suicidal behaviors (SBs) and there is substantial evidence suggesting that certain personality traits may increase individual vulnerability to suicide. METHOD: We investigated relationships of personality traits with two SBs in a cohort (n=1140) of 21- to 24-year-old adults, representative of the general population of Quebec. Subjects were assessed using a series of structured diagnostic and personality trait questionnaires. Multivariate logistic regression analyses were employed to identify personality trait correlates of suicide-attempt history and serious suicidal ideation in the context of other known risk factors, such as psychopathology and experiences of childhood sexual and physical abuse. RESULTS: Traits of conduct problems contributed to both suicide attempts [odds ratio (OR) 1.03, 95% confidence interval (CI) 1.01-1.06] and suicidal ideation (OR 1.04, 95% CI 1.02-1.07), while identity problems (OR 1.10, 95% CI 1.07-1.13) and gender-moderated impulsivity contributed exclusively to suicidal ideation. CONCLUSIONS: Personality traits may make independent contributions to current suicidal ideation and previous suicide attempts in certain subgroups of suicidal individuals. In order to further explore their utility as markers of suicide risk and targets of intervention further investigation in clinical samples and other cultural and age groups is necessary.
