Suicidal ideation, suicide attempts, and HIV infection.

A cross-sectional study was performed to investigate the prevalence and predictors of suicidal ideation and past suicide attempt in an Australian sample of human immunodeficiency virus (HIV)-positive and HIV-negative homosexual and bisexual men. Sixty-five HIV-negative and 164 HIV-positive men participated. A suicidal ideation score was derived from using five items selected from the Beck Depression Inventory and the General Health Questionnaire (28-item version). Lifetime and current prevalence rates of psychiatric disorder were evaluated with the Diagnostic Interview Schedule Version-III-R. The HIV-positive (Centers for Disease Control and Prevention [CDC] Stage IV) men (n = 85) had significantly higher total suicidal ideation scores than the asymptomatic HIV-positive men (CDC Stage II/III) (n = 79) and the HIV-negative men. High rates of past suicide attempt were detected in the HIV-negative (29%) and HIV-positive men (21%). Factors associated with suicidal ideation included being HIV-positive, the presence of current psychiatric disorder, higher neuroticism scores, external locus of control, and current unemployment. In the HIV-positive group analyzed separately, higher suicidal ideation was discriminated by the adjustment to HIV diagnosis (greater hopelessness and lower fighting spirit), disease factors (greater number of current acquired immunodeficiency syndrome [AIDS]-related conditions), and background variables (neuroticism). Significant predictors of a past attempted suicide were a positive lifetime history of psychiatric disorder (particularly depression diagnoses), a lifetime history of infection drug use, and a family history of suicide attempts. The findings indicate increased levels of suicidal ideation in symptomatic HIV-positive men and highlight the role that multiple psychosocial factors associated with suicidal ideation and attempted suicide play in this population.

Personality traits as correlates of suicidal ideation, suicide attempts, and suicide completions: a systematic review.

OBJECTIVE: Involvement of personality traits in susceptibility to suicidality has been the subject of research since the 1950s. Because of the diversity of conceptual and methodological approaches, the extent of their independent contribution has been difficult to establish. Here, we review conceptual background and empirical evidence investigating roles of traits in suicidal behaviors. METHOD: We selected original studies published in English in MEDLINE and PsycINFO databases, focusing on suicidal ideation, suicide attempts, or suicide completions, and using standardized personality measures. RESULTS: Most studies focused on investigating risk for suicide attempts. Hopelessness, neuroticism, and extroversion hold the most promise in relation to risk screening across all three suicidal behaviors. More research is needed regarding aggression, impulsivity, anger, irritability, hostility, and anxiety. CONCLUSION: Selected personality traits may be useful markers of suicide risk. Future research needs to establish their contributions in relation to environmental and genetic variation in different gender, age, and ethnocultural groups.

Self-reported life-weariness, death-wishes, suicidal ideation, suicidal plans and suicide attempts in general population surveys in the north of Sweden 1986 and 1996.

BACKGROUND: The aims of present study were to assess the prevalence of suicidal expression in the general population, to compare prevalences over time, to identify risk groups and to examine the evidence regarding the proposition that there is a continuous sequence of suicidal expressions with an underlying gradient of severity. METHOD: Two postal questionnaire studies were conducted, in 1986 and in 1996, involving representative samples of about 700 and 1000 persons respectively, in the age range 18-65 years. Response rates of 76% and 64%, respectively, were obtained. RESULTS: A higher proportion (34%) reported some degree of suicidal expression during the past year in the 1996 survey, compared to 1986 (23%). This was mainly attributed to higher reporting of life-weariness and death-wishes, since there was a simultaneous lower reporting of suicidal ideation (12.5% vs 8.6%). The total lifetime incidence of suicidal expression was identical (52%) in both studies. Respective proportions of 0.6% and 0.2% reported that they had made a suicide attempt during the last year, and 2.6% and 2.7%, respectively, during their lifetime. Higher prevalences of combined suicidal expression during the previous year were reported by women, younger persons, those living alone and women living in urban areas. Concerning suicidal ideation during last year, no gender differences were found. For a total of 21% of those reporting some degree of suicidal expressions during the past year, no simple cumulative relationship between the different types of suicidal expression was found. CONCLUSIONS: It is possible to use a postal questionnaire approach for studies on suicidal expression in the general population, and the study indicates that such suicidal expression is fairly prevalent. The pronounced gender differences concerning most types of suicidal behaviours and expression are not valid for suicidal ideation, which is important to consider in a preventional context.

Relationship of sexual orientation to substance use, suicidal ideation, suicide attempts, and other factors in a population of homeless adolescents.

PURPOSE: To explore the relationship of sexual orientation and gender to four sets of factors: (a) family history, (b) incarceration, (c) substance use, and (d) depression and suicide, in a population of homeless adolescents. METHODS: A sample of homeless adolescents was recruited in Portland, Oregon and assessed using semi-structured interviews at baseline, three months and six months. A total of 532 youths (216 females and 316 males) provided data on sexual orientation and other variables. Heterosexual (n = 391) and non-heterosexual youths (n = 141) were compared on all sets of factors, primarily using logistic regressions. RESULTS: 44.9% of females identified as lesbian or bisexual, while only 13.9% of males identified as gay or bisexual. Gay, lesbian, bisexual, and "unsure" (GLBU) youths were less likely to have been in foster care or arrested, but were more likely to have spent time in a locked mental health treatment facility. More than one-third of all participants reported use of injection drugs. GLBU youths were more likely to have recently used amphetamines and to have injected drugs, however, gay-bisexual males were less likely to have recently used marijuana. GLBU status was associated with recent measures of depression and suicidal ideation, but not with lifetime measures. Associations of sexual orientation with several lifetime measures were different than with prospective measures, demonstrating the limitations of using lifetime measures rather than recent or prospective measures. CONCLUSIONS: This population of homeless adolescents appears to be higher in its high rate of injection drug use and the large proportion of females who identify as lesbian or bisexual than found in other studies. The high rates of depression and suicidal ideation, especially among GLBU youth, are of great concern.

Use of the modified scale for suicidal ideation with suicide ideators and attempters.

The Modified Scale for Suicidal Ideation was administered to, and subsequently cross-validated on, a large sample of suicide ideators and attempters. Results confirmed previous reliability estimates and provided convincing evidence of the scale's concurrent, construct, discriminate, and predictive validity. The utility of the scale in screening with high-risk populations and other areas of critical need it addresses are discussed.

Familial transmission of suicidal ideation and suicide attempts: evidence from a general population sample.

The goals of the study were (1) to determine the association between parental and offspring suicidal ideation and suicide attempts among adult offspring in a general community sample, and (2) to examine the extent to which this association can be explained by mediating processes of mental disorders. Data were drawn from the National Comorbidity Survey (n=8098), a representative household sample of adults aged 15-54 in the United States. The relationships between suicidal ideation and suicide attempts among adult offspring and suicidal ideation and suicide attempt in their parents, compared with those in parents not characterized by suicidal ideation or suicide attempts, were calculated using multiple logistic regression analyses. Analyses were adjusted for differences in sociodemographic characteristics and for mental disorders. Results showed that parental suicidal ideation was associated with a significantly increased likelihood of suicidal ideation [OR=1.7 (1.2, 2.5)] and suicide attempt [OR=1.4 (0.9, 2.1)] among offspring. Parental suicide attempt was associated with increased odds of suicidal ideation [OR=2.0 (1.4, 2.9)] and suicide attempt [OR=2.2 (1.4, 3.4)] among offspring. Comorbid mental disorders contributed to the strength of these associations, but with the exception of the link between parental suicidal ideation and offspring suicide attempt, all remained statistically significant even after adjustment. These data provide initial evidence of familial linkages (parent-offspring) of suicidal ideation and behavior among a sample of adults representative of the US population. The data suggest that comorbid mental disorders contribute to these associations but do not completely account for them. The findings are consistent with and extend results from family, clinical, and high-risk studies suggesting that a familial risk of suicidal ideation and suicide behavior occurs in the general population. Implications for prevention and future research are discussed.

Associations of body mass index and perceived weight with suicide ideation and suicide attempts among US high school students.

BACKGROUND: Previous research with adolescents has shown associations of body weight and perceptions of body size with suicide ideation and suicide attempts, but it is unclear whether these associations are direct or whether a mediating effect exists. OBJECTIVES: To determine if body mass index and perceived weight are associated significantly with suicide ideation and suicide attempts, controlling for weight control practices, and if perceived weight mediates the associations of body mass index with suicide ideation and suicide attempts. DESIGN, SETTING, AND PARTICIPANTS: Data were analyzed from the 2001 Youth Risk Behavior Survey, a school-based survey administered to a nationally representative sample of students in grades 9 through 12 (N = 13 601). MAIN OUTCOME MEASURE: Self-reported past-year suicide ideation and suicide attempts, compared by perceived weight and body mass index category, calculated from self-reported height and weight. RESULTS: Body mass index category was associated significantly with suicide ideation (among all students) and suicide attempts (among white and Hispanic students) without perceived weight in the model but not with perceived weight added to the model. In contrast with those who perceive themselves as about the right weight, students who perceived themselves as very underweight (odds ratio [OR], 2.29 [95% confidence interval (CI), 1.46-3.59]), slightly underweight (OR, 1.36 [95% CI, 1.03-1.79]), slightly overweight (OR, 1.33 [95% CI, 1.12-1.58]), and very overweight (OR, 2.50 [95% CI, 1.73-3.60]) had greater adjusted odds of suicide ideation. Among white students, perceiving oneself as very underweight (OR, 3.04 [95% CI, 1.40-6.58]) or very overweight (OR, 2.74 [95% CI, 1.21-6.23]) was associated with greater odds of suicide attempts. Perceiving oneself as very underweight was associated with greater odds for suicide attempts among black (OR, 2.86 [95% CI, 1.10-7.45]) and Hispanic (OR, 3.40 [95% CI, 1.54-7.51]) students. CONCLUSIONS: How adolescents perceive their body weight may be more important than their actual weight in terms of increased likelihood of suicidal behavior. Regardless of body mass index, extreme perceptions of weight appear to be significant risk factors for suicidal behavior; important racial/ethnic differences exist.

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.

Suicidal ideation and suicide attempts in body dysmorphic disorder.

OBJECTIVE: Because suicidality in body dys-morphic disorder (BDD) has received little investigation, this study examined rates, correlates, predictors, and other aspects of suicidal ideation and suicide attempts in this disorder. METHOD: From January 2001 to June 2003, 200 subjects with DSM-IV BDD recruited from diverse sources were assessed with standard measures. RESULTS: Subjects had high rates of lifetime suicidal ideation (78.0%) and suicide attempts (27.5%). Body dysmorphic disorder was the primary reason for suicidal ideation in 70.5% of those with a history of ideation and nearly half of subjects with a past attempt. Suicidal subjects often did not reveal their BDD symptoms to their clinician. In univariate analyses, both suicidal ideation and suicide attempts were associated with lifetime functional impairment due to BDD (p < .001), current functional impairment (p < .001 to < .05), lifetime bipolar disorder (p < .05), any personality disorder (p < .05 to .001), and comorbid borderline personality disorder (p < .01 to < .001). A history of suicidal ideation (but not suicide attempts) was additionally associated with comorbid lifetime major depression (p = .001). A history of suicide attempts (but not suicidal ideation) was additionally associated with delusional appearance beliefs (p = .01) and lifetime posttraumatic stress disorder (PTSD), an eating disorder, or a substance use disorder (p < .001 to < .05). In logistic regression analyses, suicidal ideation was significantly predicted by comorbid major depression (p = .010) and greater lifetime impairment due to BDD (p = .003); suicide attempts were significantly predicted by PTSD (p = .011), a substance use disorder (p = .011), and greater lifetime impairment due to BDD (p = .005). CONCLUSION: Individuals with BDD have high rates of suicidal ideation and suicide attempts. Lifetime impairment due to BDD and certain comorbid disorders are associated with suicidality.

Substance abuse and drug-related death, suicidal ideation, and suicide: a review.

The high mortality rate among drug users, which is partly due to the HIV epidemic and partly due to drug-related accidental deaths and suicides, presents a major public health problem. Knowing more about prevalence, incidence, and risk factors is important for the development of rational preventive and therapeutic programs. This article attempts to give an overview of studies of the relations between substance abuse, suicidal ideation, suicide, and drug-related death. Research in this field is hampered by the absence of clear definitions, and results of studies are rarely comparable. There is, however, consensus about suicidal ideation being a risk factor for suicide attempts and suicide. Suicidal ideation is also a predictor of suicide, especially among drug users. It is correlated with an absence of family support, with the severity of the psychosocial dysfunctioning, and with multi-drug abuse, but also with requests for treatment. Every clinical examination of a drug user, not only of those who are depressed, should address the possible presence of suicidal ideation, as well as its intensity and duration.

Anxiety disorders and risk for suicidal ideation and suicide attempts: a population-based longitudinal study of adults.

CONTEXT: Controversy exists whether anxiety disorders are independently associated (ie, after adjusting for comorbid mental disorders) with suicidal ideation and suicide attempts. OBJECTIVE: To examine whether anxiety disorders are risk factors for suicidal ideation and suicide attempts in a large population-based longitudinal study. METHODS: Data come from the Netherlands Mental Health Survey and Incidence Study, a prospective population-based survey with a baseline and 2 follow-up assessments over a 3-year period. The Composite International Diagnostic Interview was used to assess DSM-III-R mental disorders. Lifetime diagnoses of anxiety disorders (social phobia, simple phobia, generalized anxiety disorder, panic disorder, agoraphobia, obsessive-compulsive disorder) were assessed at baseline. Multiple logistic regression analyses were used to examine whether anxiety disorders were associated with suicidal ideation and attempts at baseline (n = 7076) and whether anxiety disorders were risk factors for subsequent onset of suicidal ideation and attempts (n = 4796). RESULTS: After adjusting for sociodemographic factors and all other mental disorders assessed in the survey, baseline presence of any anxiety disorder was significantly associated with suicidal ideation and suicide attempts in both the cross-sectional analysis (adjusted odds ratio for suicidal ideation, 2.29; 95% confidence interval, 1.85-2.82; adjusted odds ratio for suicidal attempts, 2.48; 95% confidence interval, 1.70-3.62) and longitudinal analysis (adjusted odds ratio for suicidal ideation, 2.32; 95% confidence interval, 1.31-4.11; adjusted odds ratio for suicide attempts, 3.64; 95% confidence interval, 1.70-7.83). Further analyses demonstrated that the presence of any anxiety disorder in combination with a mood disorder was associated with a higher likelihood of suicide attempts in comparison with a mood disorder alone. CONCLUSIONS: This is the first study to demonstrate that a preexisting anxiety disorder is an independent risk factor for subsequent onset of suicidal ideation and attempts. Moreover, the data clearly demonstrate that comorbid anxiety disorders amplify the risk of suicide attempts in persons with mood disorders. Clinicians and policymakers need to be aware of these findings, and further research is required to delineate whether treatment of anxiety disorders reduces the risk of subsequent suicidal behavior.

Asthma, suicidal ideation, and suicide attempts: findings from the Baltimore epidemiologic catchment area follow-up.

OBJECTIVES: We examined cross-sectional and longitudinal associations between asthma, suicidal ideation, and suicide attempt among adults in the community. METHODS: Data were drawn from 3 waves (1981,1982,1993-1996) of the Baltimore follow-up of the Epidemiologic Catchment Area study. Multiple logistic regression analyses were used to examine associations between asthma, asthma treatment, suicidal ideation, suicide attempt, and suicide completion. RESULTS: Asthma at wave 1 was associated with a significantly increased odds of suicidal ideation (odds ratio [OR] = 2.33; confidence interval [CI] = 1.03, 5.25) and suicide attempt (OR=3.54; CI=1.4, 8.99), which persisted independent of lifetime National Institute of Mental Health Diagnostic Interview Schedule/Diagnostic and Statistical Manual of Mental Disorders, Third Edition major depression and treatment for asthma at wave 2. CONCLUSIONS: These findings provide preliminary evidence suggestive of an association between asthma and an increased likelihood of suicidal ideation and suicide attempt among adults in the community. Neither lifetime major depression nor treatment for asthma explained this relation. These results provide important directions for future research, and if replicated these data may have clinical and public health implications.

[Survey of suicidal ideation and suicide attempts in outpatients at 50 general hospitals in Beijing].

OBJECTIVE: Describe the prevalence and risk factors for suicidal ideation and suicide attempt among outpatients at general hospitals in Beijing. METHODS: Trained psychiatric nurses obtained data about the characteristics of suicidal thoughts and suicide attempts from 2877 persons 15 years of age or older who were consecutive outpatients at 35 level-1, 8 level-2 and 7 level-3 general hospitals selected from all hospitals in Beijing by stratified random sampling. Logistic regression analysis was used to identify risk factors for suicidal ideation and suicide attempt. RESULTS: The lifetime prevalence of suicidal ideation and suicide attempt were 6.08% (95% CI: 5.25% - 7.25%) and 1.18% (0.82% - 1.65%), respectively. Mutivariate logistic analysis found that the most important risk factors for suicidal ideation were hopelessness in the prior year (OR = 7.96), current depression (OR = 3.41), younger age (OR for < 35 = 2.83; OR for 35 - 55 = 2.08), having a blood relative with prior suicidal behavior (OR = 2.58), and so forth; the most important risk factors for suicide attempt were younger age (OR for < 35 = 4.96; OR for 35 - 55 = 4.40), hopelessness in the prior year (OR = 4.02), self-report of health status in last weeks as poor (OR = 2.81), not currently married (never married, divorced, widowed, etc) (OR = 2.80), and so forth. Four variables were independent risk factors for both suicidal ideation and suicide attempt: hopelessness in the last year, younger age, having associates with prior suicidal behavior and female gender. CONCLUSIONS: Many patients treated at medical, surgical and other outpatient departments of general hospitals in Beijing are depressed and at risk for suicide; this is particularly true of young female patients who feel hopeless about their future. Outpatient clinicians need to be trained to identify such patients, to assess the severity of their psychological problems and, if necessary, to provide appropriate treatment or refer them for psychiatric evaluation.

Suicidal ideation and suicide attempts in recent-onset schizophrenia.

The objective of this study was to predict suicidality in people with schizophrenia. Ninety-six patients with recent-onset schizophrenia were rated every 2 weeks for 1 year to examine (1) the temporal course of suicidal ideation and suicide attempts and (2) the extent to which anxiety, depression, and mild suicidal ideation were followed by significant suicidal ideation or a suicide attempt. The severity of suicidality changed rapidly. Low levels of suicidal ideation increased the risk for significant suicidal ideation or a suicide attempt during the subsequent 3 months. Depression was moderately correlated with concurrent suicidality, but not independently associated with future suicidality. Therefore, low levels of suicidal ideation may predict future suicidal ideation or behavior better than depressed mood in individuals with schizophrenia.

Major depressive disorder, suicidal ideation, and suicide attempt in twins discordant for cannabis dependence and early-onset cannabis use.

BACKGROUND: Previous research has reported both a moderate degree of comorbidity between cannabis dependence and major depressive disorder (MDD) and that early-onset cannabis use is associated with increased risks for MDD. OBJECTIVE: To examine whether associations between both lifetime cannabis dependence and early cannabis use and measures of MDD, suicidal ideation, and suicide attempt persist after controlling for genetic and/or shared environmental influences. DESIGN: Cross-sectional survey of twin pairs discordant for lifetime cannabis dependence and those discordant for early cannabis use. SETTING: General population sample of twins (median age, 30 years). PARTICIPANTS: Two hundred seventy-seven same-sex twin pairs discordant for cannabis dependence and 311 pairs discordant for early-onset cannabis use (before age 17 years). MAIN OUTCOME MEASURES: Self-report measures of DSM-IV-defined lifetime MDD, suicidal ideation, and suicide attempt. RESULTS: Individuals who were cannabis dependent had odds of suicidal ideation and suicide attempt that were 2.5 to 2.9 times higher than those of their non-cannabis-dependent co-twin. Additionally, cannabis dependence was associated with elevated risks of MDD in dizygotic but not in monozygotic twins. Those who initiated cannabis use before age 17 years had elevated rates of subsequent suicide attempt (odds ratio, 3.5 [95% confidence interval, 1.4-8.6]) but not of MDD or suicidal ideation. Early MDD and suicidal ideation were significantly associated with subsequent risks of cannabis dependence in discordant dizygotic pairs but not in discordant monozygotic pairs. CONCLUSIONS: Comorbidity between cannabis dependence and MDD likely arises through shared genetic and environmental vulnerabilities predisposing to both outcomes. In contrast, associations between cannabis dependence and suicidal behaviors cannot be entirely explained by common predisposing genetic and/or shared environmental predispositions. Previously reported associations between early-onset cannabis use and subsequent MDD likely reflect shared genetic and environmental vulnerabilities, although it remains possible that early-onset cannabis use may predispose to suicide attempt.

Relationships between obesity and DSM-IV major depressive disorder, suicide ideation, and suicide attempts: results from a general population study.

OBJECTIVES: This study sought to test the relationships between relative body weight and clinical depression, suicide ideation, and suicide attempts in an adult US general population sample. METHODS: Respondents were 40,086 African American and White participants interviewed in a national survey. Outcome measures were past-year major depression, suicide ideation, and suicide attempts diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The primary predictor was relative body weight, treated both continuously (i.e., body mass index [BMI]) and categorically in logistic regression analyses. Covariates included age, income and education, disease status, and drug and alcohol use. RESULTS: Relative body weight was associated with major depression, suicide attempts, and suicide ideation, although relationships were different for men and women. Among women, increased BMI was associated with both major depression and suicide ideation. Among men, lower BMI was associated with major depression, suicide attempts, and suicide ideation. There were no racial differences. CONCLUSIONS: Differences in BMI, or weight status, were associated with the probability of past-year major depression, suicide attempts, and suicide ideation. Longitudinal studies are needed to differentiate the causal pathways and mechanisms linking physical and psychiatric conditions.

Suicidal ideation and suicide attempts in treatment-seeking pathological gamblers.

This study assessed rates and correlates of suicidal ideation and suicide attempts in individuals seeking treatment for pathological gambling. At intake to gambling treatment programs, 342 pathological gamblers completed the Addiction Severity Index and the South Oaks Gambling Screen. Participants were categorized into three groups: no suicidal ideation (N = 175, 51%), suicidal ideation alone (N = 109, 32%), and suicide attempters (N = 58, 17%). After controlling for gender, age, treatment site, and substance abuse treatment histories, differences among the groups emerged in terms of severity of psychiatric, social/family, and gambling problems. Compared with nonsuicidal gamblers, those with suicidal ideation suffered from more psychiatric symptoms, were less satisfied with their living situations, and experienced more days of conflict in the month before entering gambling treatment. Compared with pathological gamblers with no history of suicidal ideation, those with suicidal ideation spent more money gambling in the month before entering treatment, reported greater cravings for gambling, and had higher South Oaks Gambling Screen scores. These data confirm other reports of high rates of suicidality in pathological gamblers and may suggest the need for more intensive and focused treatments in pathological gamblers with suicidality.

Evaluation and treatment of patients with suicidal ideation.

Suicidal ideation is more common than completed suicide. Most persons who commit suicide have a psychiatric disorder at the time of death. Because many patients with psychiatric disorders are seen by family physicians and other primary care practitioners rather than by psychiatrists, it is important that these practitioners recognize the signs and symptoms of the psychiatric disorders (particularly alcohol abuse and major depression) that are associated with suicide. Although most patients with suicidal ideation do not ultimately commit suicide, the extent of suicidal ideation must be determined, including the presence of a suicide plan and the patient's means to commit suicide.
