Anxiety disorders associated with suicidal ideation and suicide attempts in the National Comorbidity Survey

This study examined the relationship between anxiety disorders and suicidal ideation or suicide attempts in a nationally representative sample (N = 5877; age, 15-54; response rate, 82.4%). A modified version of the Composite International Diagnostic Interview was used to make DSM-III-R mental disorder diagnoses. Two multivariate logistic regression analyses were performed with suicidal ideation (N = 754) and suicide attempts (N = 259) as dependent variables. In each regression, the independent variables entered were lifetime social phobia, panic disorder, agoraphobia, generalized anxiety disorder, simple phobia, and posttraumatic stress disorder (PTSD). Covariates in the analyses were sociodemographics, lifetime mood disorders, substance use disorders, nonaffective psychosis, antisocial personality disorder, and presence of three or more lifetime DSM-III-R diagnoses. PTSD was significantly associated with suicidal ideation (adjusted odds ratio = 2.79; p < 0.01) and suicide attempts (adjusted odds ratio = 2.67; p < 0.01). None of the other anxiety disorders were significantly associated with suicidal ideation or attempts. The robust association between PTSD and suicide attempts has important implications for psychiatric assessment of suicidal behavior. Future research is required to investigate the mechanisms underlying the relationship between PTSD and suicidal behavior.     

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.     

Mental disorders and risk of suicide attempt in prisoners

Background

Mental disorders are overrepresented in prisoners, placing them at an increased risk of suicide. Advancing our understanding of how different mental disorders relate to distinct stages of the suicidal process—the transition from ideation to action—would provide valuable information for clinical risk assessment in this high-risk population.

Methods

Data were drawn from a representative sample of 1212 adults (1093 men) incarcerated across 13 New Zealand prisons, accounting for 14% of the national prison population. Guided by an ideation-to-action framework, three mutually exclusive groups of participants were compared on the presence of mental disorders assessed by validated DSM-IV diagnostic criteria: prisoners without any suicidal history (controls; n = 778), prisoners who thought about suicide but never made a suicide attempt (ideators; n = 187), and prisoners who experienced suicidal ideation and acted on such thoughts (attempters; n = 247).

Results

One-third (34.6%) of participants reported a lifetime history of suicidal ideation, of whom 55.6% attempted suicide at some point (19.2% of all prisoners). Suicidal outcomes in the absence of mental disorders were rare. Whilst each disorder increased the odds of suicidal ideation (OR range 1.73–4.13) and suicide attempt (OR range 1.82–4.05) in the total sample (n = 1212), only a select subset of disorders was associated with suicide attempt among those with suicidal ideation (n = 434). Drug dependence (OR 1.65, 95% CI 1.10–2.48), alcohol dependence (OR 1.89, 95% CI 1.26–2.85), and posttraumatic stress disorder (OR 2.09, 95% CI 1.37–3.17) distinguished attempters from ideators.

Conclusion

Consistent with many epidemiological studies in the general population, our data suggest that most mental disorders are best conceptualized as risk factors for suicidal ideation rather than for suicide attempt. Once prisoners consider suicide, other biopsychosocial factors beyond the mere presence of mental disorders may account for the progression from thoughts to acts of suicide.

     

Comorbidity patterns in adolescents and young adults with suicide attempts

The role of comorbidity as a risk for suicide attempts is investigated in a random sample of 3021 young adults aged 14–24 years. The M-CIDI, a fully standardized and modified version of the Composite International Diagnostic Interview, was used for the assessment of various DSM-IV lifetime and 12-month diagnoses as well as suicidal ideation and suicide attempts. Of all suicide attempters, 91% had at least one mental disorder, 79% were comorbid or multimorbid respectively and 45% had four or more diagnoses (only 5% in the total sample reached such high levels of comorbidity). Suicide attempters with more than three diagnoses were 18 times more likely (OR = 18.4) to attempt suicide than subjects with no diagnosis. Regarding specific diagnoses, multivariate comorbidity analyses indicated the highest risk for suicide attempt in those suffering from anxiety disorder (OR = 4.3), particularly posttraumatic stress disorder followed by substance disorder (OR = 2.2) and depressive disorder (OR = 2.1). Comorbidity, especially when anxiety disorders are involved, increases the risk for suicide attempts considerably more than any other individual DSM-IV diagnoses.

Psychosocial profile of suicide ideators, attempters and completers in India

The study aims to determine the psychological profile of suicide ideators, attempters and completers in a tertiary care teaching hospital. A total of 260 suicidal ideators, 58 attempters and 55 completers were studied. The majority of ideators, attempters and completers were 26-35 years of age, males (except attempters who were predominantly females), married, literate up to high school, employed (ideators) or housewives (attempters and completers). The suicide ideators, attempters and completers who had a past history of attempt were 6.9%, 24.1% and 18.2% respectively. Family history of attempted suicide or completed suicide was also common among patients suffering from depression. In suicidal ideators, mixed anxiety and depressive disorder was the most common psychiatric diagnosis followed by major depression and schizophrenia. Among suicide attempters, adjustment disorder with depression was the most common diagnosis. The most common method of suicide attempt was organophosphorus compound intake whereas in suicide completers, the most common method in use was hanging. The patients with suicidal ideation or attempt need careful evaluation, early intervention and long term follow up.     

Use of alcohol and drugs to self-medicate anxiety disorders in a nationally representative sample

This study examined the prevalence and correlates of self-medication of anxiety disorders with alcohol and drugs in a nationally representative sample (N = 5877). A modified version of the Composite International Diagnostic Interview was used to make DSM-III-R mental disorder diagnoses. Frequencies of self-medication ranged from 7.9% (social phobia, speaking subtype) to 35.6% (generalized anxiety disorder). Among respondents with an anxiety disorder, self-medication was significantly associated with an increased likelihood of comorbid mood disorders, substance use disorders, distress, suicidal ideation, and suicide attempts. Self-medication behavior remained significantly associated with an increased likelihood of suicidal ideation (adjusted odds ratio = 1.66; 1.17-2.36) as well as suicide attempts (adjusted odds ratio = 2.23; 1.50-3.31), even after adjusting for a number of sociodemographic and psychiatric variables. These results suggest that individuals with anxiety disorders who self-medicate their symptoms with alcohol or drugs may be at increased risk for mood and substance use disorders and suicidal behavior.     

Parental psychopathology and the risk of suicidal behavior in their offspring: results from the World Mental Health surveys

Previous research suggests that parental psychopathology predicts suicidal behavior among offspring; however, the more fine-grained associations between specific parental disorders and distinct stages of the pathway to suicide are not well understood. We set out to test the hypothesis that parental disorders associated with negative mood would predict offspring suicide ideation, whereas disorders characterized by impulsive aggression (for example, antisocial personality) and anxiety/agitation (for example, panic disorder) would predict which offspring act on their suicide ideation and make a suicide attempt. Data were collected during face-to-face interviews conducted on nationally representative samples (N=55?299; age 18+) from 21 countries around the world. We tested the associations between a range of parental disorders and the onset and persistence over time (that is, time since most recent episode controlling for age of onset and time since onset) of subsequent suicidal behavior (suicide ideation, plans and attempts) among offspring. Analyses tested bivariate and multivariate associations between each parental disorder and distinct forms of suicidal behavior. Results revealed that each parental disorder examined increased the risk of suicide ideation among offspring, parental generalized anxiety and depression emerged as the only predictors of the onset and persistence (respectively) of suicide plans among offspring with ideation, whereas parental antisocial personality and anxiety disorders emerged as the only predictors of the onset and persistence of suicide attempts among ideators. A dose-response relation between parental disorders and respondent risk of suicide ideation and attempt was also found. Parental death by suicide was a particularly strong predictor of persistence of suicide attempts among offspring. These associations remained significant after controlling for comorbidity of parental disorders and for the presence of mental disorders among offspring. These findings should inform future explorations of the mechanisms of intergenerational transmission of suicidal behavior.     

Suicide attempt characteristics, diagnoses, and future attempts: comparing multiple attempters to single attempters and ideators

OBJECTIVE: To compare psychiatric diagnoses and future suicide attempt outcomes of multiple attempters (MAs), single attempters (SAs), and ideators. METHOD: Two hundred twenty-eight teens who reported recent ideation or a lifetime suicide attempt in a screening of 1,729 high school students completed the Adolescent Suicide Interview, which provided information on attempt number and characteristics and mood, anxiety, and substance use disorder modules of the Diagnostic Interview Schedule for Children; 191 were reinterviewed 4 to 6 years later to ascertain interval attempts and psychiatric disorder. Between screening and follow-up, 33 (17%) teens made an attempt, 12 of whom were previously classified as lifetime MAs (more than one attempt) and six as SAs. RESULTS: MAs more often met criteria for any one of the DSM diagnoses assessed at baseline (mood, anxiety, or substance use disorder; 71%), compared with SAs (39%) and ideators (41%), and at follow-up (mood, anxiety, substance use, or disruptive behavior disorder; 69%) compared with SAs (36%) (p <.05). As reported at baseline, MAs (versus SAs) more often wished to die during their attempt (53% versus 23%), less often planned their attempt for intervention (44% versus 76%), and more often regretted recovery (26% versus 7%; p <.05). Baseline MAs had significantly higher odds of making a later attempt compared to ideators (odds ratio 4.0, 95% confidence interval 1.5-10.2) and SAs (odds ratio 4.6, 95% confidence interval 1.0-20.2). No participants committed suicide during follow-up. SAs who made another attempt (versus those who did not) more often met criteria for a baseline anxiety disorder and more often wished to die during their baseline attempt. CONCLUSIONS: MAs more strongly predict later suicidality and diagnosis than SAs and ideation. Forms that assess past suicide attempts should routinely inquire about frequency of attempts. The similarity between the present findings and those of clinical samples suggests that screening may yield a representative sample of suicide attempters and ideators.     

Relationship between self-disclosure and serious suicidal behavior

The ability to predict which suicidal patient is at high risk for a serious attempt is an important clinical problem. On the basis of our clinical research, we hypothesized that self-disclosure may be an important personality variable differentiating suicide attempters and completers. We assessed 80 patients with depressive disorder, divided into four groups of 20 each: suicidal ideation only, nonserious suicide attempts, severe suicide attempts, and no suicidal behavior. Comparisons were also made with 20 healthy controls. All subjects completed Jourad's Self-Disclosure Questionnaire (JSDQ), as well as scales measuring depression/anxiety and hopelessness. The lack of willingness for self-disclosure significantly differentiated the serious attempters from the suicide ideators and mild attempters. The relationship of self-disclosure and more lethal suicide attempts did not appear to be mediated by depression, anxiety, or hopelessness. This preliminary study indicates that self-disclosure may be a promising field for assessment, therapy, and prevention in suicidal patients. Further studies are needed to investigate related variables, wider patients groups, and the use of different instruments.     

Is sexual orientation related to mental health problems and suicidality in young people?

BACKGROUND: This study examines the extent to which gay, lesbian, and bisexual young people are at increased risk of psychiatric disorder and suicidal behaviors using data gathered on a New Zealand birth cohort studied to age 21 years. METHODS: Data were gathered during the course of the Christchurch Health and Development Study, a 21-year longitudinal study of a birth cohort of 1265 children born in Christchurch, New Zealand. At 21 years of age, 1007 sample members were questioned about their sexual orientation and relationships with same-sex partners since the age of 16 years. Twenty-eight subjects (2.8%) were classified as being of gay, lesbian, or bisexual sexual orientation. Over the period from age 14 to 21 years, data were gathered on a range of psychiatric disorders that included major depression, generalized anxiety disorder, conduct disorder, and substance use disorders. Data were also gathered on suicidal ideation and suicide attempts. RESULTS: Gay, lesbian, and bisexual young people were at increased risks of major depression (odds ratio [OR], 4.0; 95% confidence interval [CI], 1.8-9.3), generalized anxiety disorder (OR, 2.8; 95% CI, 1.2-6.5), conduct disorder (OR, 3.8; 95% CI, 1.7-8.7), nicotine dependence (OR, 5.0; 95%, CI, 2.3-10.9), other substance abuse and/or dependence (OR, 1.9; 95% CI, 0.9-4.2), multiple disorders (OR, 5.9; 95% CI, 2.4-14.8), suicidal ideation (OR, 5.4; 95% CI, 2.4-12.2), and suicide attempts (OR, 6.2; 95% CI, 2.7-14.3). CONCLUSIONS: Findings support recent evidence suggesting that gay, lesbian, and bisexual young people are at increased risk of mental health problems, with these associations being particularly evident for measures of suicidal behavior and multiple disorder.     

Lifetime comorbidity of antisocial personality disorder and anxiety disorders among adults in the community

The association between lifetime anxiety disorders, conduct disorder (CD), and antisocial personality disorder (ASPD) among adults in the community was explored. Data were drawn from the National Comorbidity Survey (n = 5,877), a representative community sample of adults aged 15-54 in the 48 contiguous US states. Multiple logistic regression analyses were used to determine the association between anxiety disorders, CD and ASPD, and between the co-occurrence of anxiety disorders and ASPD in the likelihood of comorbid substance use and affective disorders, suicidal ideation (SI) and suicide attempt (SA). Out of the 3.3% of adults with ASPD, over half (54.33%) had a comorbid anxiety disorder (lifetime). Similarly, 42.31% of adults with a history of CD (9.4%) who did not meet criteria for ASPD had a lifetime anxiety disorder. Social phobia [OR = 1.65 (1.01, 2.7)] and post-traumatic stress disorder [OR = 2.28 (1.3, 4.0)] were associated with significantly increased odds of ASPD, after adjusting for differences in sociodemographic characteristics and other psychiatric comorbidity. Major depression was no longer significantly associated with ASPD after adjusting for anxiety disorders. The comorbidity of anxiety disorders and ASPD was associated with significantly higher odds of major depression, substance use disorders, and SI and SA compared with odds among those without both disorders. These data provide initial evidence of an association between PTSD and social phobia and an increased likelihood of ASPD among adults in the community, after adjustment for comorbid affective and substance use disorders. Adults with ASPD and comorbid anxiety had significantly higher levels of comorbid major depression, alcohol dependence, and substance dependence and substantially higher rates of lifetime suicidal ideation and suicide attempts compared to adults with ASPD or anxiety disorders alone or with neither disorder. Future studies are needed to replicate this finding using longitudinal data and to investigate the possible mechanisms of the observed links between anxiety disorders and ASPD.     

Post-traumatic stress disorder among adolescents with bipolar disorder and its relationship to suicidality

OBJECTIVES: The aims of this cross-sectional pilot study were to ascertain the rates of post-traumatic stress disorder (PTSD) among adolescents with bipolar disorder (BPD) and major depressive disorder (MDD) relative to a comparison group comprised of non-affectively ill patients, and to determine whether PTSD is related to suicidal ideation and attempts. The impetus for the study was born of clinical impressions derived in the course of routine clinical practice. METHODS: Patients were screened by a single interviewer for BPD, MDD and PTSD, panic disorder, obsessive-compulsive disorder (OCD) and social phobia using the apposite modules from the Structured Clinical Interview for DSM-IV (SCID) and histories of suicidal ideation and attempts. The data were subjected to analysis using a logistic regression model. RESULTS: The database included 34 patients with BPD, 79 with MDD and 26 with a non-affective disorder. The risk for PTSD for a patient with BPD significantly exceeded that for a patient with MDD [odds ratio (OR) = 4.9, 95% confidence interval (CI) = 1.9-12.2, p = 0.001]. Patients with PTSD had an insignificantly increased risk for suicidal ideation (OR = 2.8, 95% CI = 0.9-8.9, p = 0.069), and a 4.5-fold significantly increased risk of having had a suicide attempt (OR = 4.5, 95% CI = 1.7-11.7, p = 0.002). The relationship between PTSD and suicide attempts remained significant even after controlling for the confounding effects of concurrent panic disorder, OCD and social phobia (OR = 3.4, 95% CI = 1.1-10.0, p = 0.023). CONCLUSIONS: Patients with BPD have a greater risk for PTSD than those with MDD. Post-traumatic stress disorder is significantly related to history of suicide attempts.     

Parental Mental Disorders and Suicidal Behavior in the Nigerian Survey of Mental Health and Well-Being

The objective of this study was to determine which parental mental disorders predict offspring suicidal behavior in a general adult population sample of a sub-Saharan African country. The World Health Organization Composite International Diagnostic Interview, version 3 was used to assess respondents' suicidal behaviors as well as psychopathology in their parents. The effects of parental disorders in predicting offspring suicide ideation and attempts were examined in a series of bivariate and multivariate models. Sections on suicidality were administered to the entire sample (n = 6752), but associations with parental psychopathology were examined in a subsample of respondents (n = 2143). Lifetime prevalence (95% confidence interval) of suicide ideation, plans, and attempts was 3.2% (1.4–6.5), 1.0% (0.4–7.5), and 0.7% (0.5–1.0) respectively. Parental panic disorder and substance abuse were associated with suicide ideation in offspring, but only parental panic disorder was linked to suicide attempts. Parental panic disorder predicted the onset and persistence of suicide ideation and attempts and also which persons with suicide ideation go on to make a suicide attempt. This study further affirms findings from previous studies of the role of disorders characterized by anxiety and impulse control in suicide attempts and as being a probable link in the transmission of suicidal behavior to offspring.     

Personal and family risk factors for adolescent suicidal ideation and attempts.

Despite research indicating that suicidal ideation is strongly related to future suicide attempts, there is limited data on variables associated with continued suicidal ideation and behaviors in adolescents. The objective of this study is to investigate whether personal, cognitive and family risk factors can differentiate adolescent suicidal ideation and attempts. Twenty-four attempters, 50 ideators and 50 non-suicidal adolescents (aged 14 to 25 years) were asked during an interview to complete individual and psychosocial measures. Both suicidal groups reported greater personal vulnerability and perceived their family as less functional than did the non-suicidal group. However, no differences were found between both suicidal groups. The results suggest the presence of common factors in both adolescent suicidal ideators and attempters.     

Predicting future suicide attempts among depressed suicide ideators: a 10-year longitudinal study

Suicidal ideation and attempts are a major public health problem. Research has identified many risk factors for suicidality; however, most fail to identify which suicide ideators are at greatest risk of progressing to a suicide attempt. Thus, the present study identified predictors of future suicide attempts in a sample of psychiatric patients reporting suicidal ideation. The sample comprised 49 individuals who met full DSM-IV criteria for major depressive disorder and/or dysthymic disorder and reported suicidal ideation at baseline. Participants were followed for 10 years. Demographic, psychological, personality, and psychosocial risk factors were assessed using validated questionnaires and structured interviews. Phi coefficients and point-biserial correlations were used to identify prospective predictors of attempts, and logistic regressions were used to identify which variables predicted future attempts over and above past suicide attempts. Six significant predictors of future suicide attempts were identified - cluster A personality disorder, cluster B personality disorder, lifetime substance abuse, baseline anxiety disorder, poor maternal relationship, and poor social adjustment. Finally, exploratory logistic regressions were used to examine the unique contribution of each significant predictor controlling for the others. Comorbid cluster B personality disorder emerged as the only robust, unique predictor of future suicide attempts among depressed suicide ideators. Future research should continue to identify variables that predict transition from suicidal thoughts to suicide attempts, as such work will enhance clinical assessment of suicide risk as well as theoretical models of suicide.     

Electrodermal reactivity in male and female depressive patients who later died by suicide

On the basis of earlier studies on electrodermal responsiveness in patients with suicide attempts, an investigation on electrodermal activity (EDA) in former depressive inpatients was carried out. Male and female depressive inpatients who died of suicide later and participated in an habituation experiment during their inpatient treatment were identified retrospectively and compared (strictly matched by age and sex) to depressive suicide attempters with violent or nonviolent methods, suicide ideators and a nonsuicidal depressive group. In the first part of the study only male depressives (n= 12) who had committed suicide after or during inpatient treatment were compared with their controls. The hypothesis of a expected low electrodermal responsiveness and a fast habituation as an peripheral expression of a central impulse or violence control disturbance could not be confirmed. This was done in the second part of this study. We came to the following results: 1) a tendency to a faster habituation in the violent suicides compared with nonsuicidal depressives and violent suicide attempters plus violent suicide group in male depressives compared to suicide attempters (SA), nonviolent suicide ideators and nonsuicidal depressives. 2) A significant difference with faster habituation rates in a male and female violent suicide group compared with nonsuicidal depressives and again comparing a group of male and female violent suicides and SA with nonviolent SA, suicide ideator and nonsuicidal depressive controls. These results may reflect a dysregulation of violence and impulsivity control mechanism as an underlying disorder or personality trait.     

Contributors to suicidality in rural communities: beyond the effects of depression

ABSTRACT: BACKGROUND: Rural populations experience a higher suicide rate than urban areas despite their comparable prevalence of depression. This suggests the identification of additional contributors is necessary to improve our understanding of suicide risk in rural regions. Investigating the independent contribution of depression, and the impact of co-existing psychiatric disorders, to suicidal ideation and suicide attempts in a rural community sample may provide clarification of the role of depression in rural suicidality. METHODS: 618 participants in the Australian Rural Mental Health Study completed the Composite International Diagnostic Interview, providing assessment of lifetime suicidal ideation and attempts, affective disorders, anxiety disorders and substance-use disorders. Logistic regression analyses explored the independent contribution of depression and additional diagnoses to suicidality. A receiver operating characteristic (ROC) analysis was performed to illustrate the benefit of assessing secondary psychiatric diagnoses when determining suicide risk. RESULTS: Diagnostic criteria for lifetime depressive disorder were met by 28% (174) of the sample; 25% (154) had a history of suicidal ideation. Overall, 41% (63) of participants with lifetime suicidal ideation and 34% (16) of participants with a lifetime suicide attempt had no history of depression. When lifetime depression was controlled for, suicidal ideation was predicted by younger age, being currently unmarried, and lifetime anxiety or post-traumatic stress disorder. In addition to depression, suicide attempts were predicted by lifetime anxiety and drug use disorders, as well as younger age; being currently married and employed were significant protective factors. The presence of comorbid depression and PTSD significantly increased the odds of reporting a suicide attempt above either of these conditions independently. CONCLUSIONS: While depression contributes significantly to suicidal ideation, and is a key risk factor for suicide attempts, other clinical and demographic factors played an important role in this rural sample. Consideration of the contribution of factors such as substance use and anxiety disorders to suicidal ideation and behaviours may improve our ability to identify individuals at risk of suicide. Acknowledging the contribution of these factors to rural suicide may also result in more effective approaches for the identification and treatment of at-risk individuals.     

Losing the battle: Perceived status loss and contemplated or attempted suicide in older adults

Objective

While loss of socioeconomic status (SES) has been linked to suicidal behavior, it is unclear whether this experience is merely a downstream effect of psychopathology (“downward drift”), a sign of hardship, or an independent psychological contributor to suicide risk. We examined the association between the subjective experience of status loss and suicidal behavior and ideation in old age, while accounting for potential confounders. We were also interested in whether status loss was associated with mere thoughts of suicide vs. suicidal behavior.

Methods

Fifty older (55+) depressed suicide attempters, 29 depressed suicide ideators with no history of attempted suicide, 38 nonsuicidal depressed participants, and 45 nonpsychiatric controls underwent detailed clinical characterization and reported their current and highest lifetime SES.

Results

Suicide attempters were more likely to report a decline in their SES compared to healthy controls and nonsuicidal depressed older adults, while not differing from suicide ideators. This difference was not explained by objective predictors of SES, including education, financial difficulties, and the presence of addiction. Interestingly, while the current SES of suicide attempters was much lower than that of comparison groups, their reported highest lifetime SES was just as high, despite the differences in education.

Conclusion

In older adults, the experience of status loss is associated with contemplated and attempted suicide even after accounting for objective indicators of social status and psychopathology. It is possible that suicidal individuals retrospectively inflate their previous status, making their current standing appear even worse by comparison.     

A comparison of the medical lethality of suicide attempts in bipolar and major depressive disorders

Objectives:  Among mood disorders, bipolar disorder (BPD) is often noted to involve the highest rates of suicide attempts and possibly of completion. This study sought to determine whether suicide attempters with BPD exhibit suicide attempts with higher lethality than attempters with major depressive disorder (MDD) and to explore differences in clinical features associated with suicidal acts.
Methods:  Mood disordered suicide attempters were interviewed about Axis I and II diagnoses, lifetime history of suicide attempts, suicidal intent, suicidal ideation, the medical lethality of their most severe suicide attempt, severity of depression, hopelessness, lifetime aggression, and impulsivity.
Results:  The maximum lethality of suicidal acts tended to be higher among BPD attempters compared with those with MDD. However, there were no differences in the number of suicide attempts, intent to die or suicidal ideation. Suicide attempters with BPD reported higher levels of aggression and impulsivity but less hopelessness compared with MDD attempters. These differences could not be explained by Cluster B personality disorder comorbidity. Of note, within the BPD group, but not the MDD group, males reported suicidal acts with higher lethality. Multivariate analyses suggested that risk for more lethal suicide attempts is associated with BPD and male sex and that bipolar males appear to be especially vulnerable to these behaviors.
Conclusions:  Males with BPD make more lethal suicide attempts than females with BPD, an effect not observed among the MDD sample. Our findings suggest that higher rates of suicidal behavior in BPD may be due to a specific effect of BPD on males, leading to more dangerous suicidal behaviors. This effect, together with the larger proportion of males in the BPD group compared with the MDD group may lead to higher rates of reported attempted and completed suicide.     

Characteristics of the “young-old” and “old-old” community-dwelling suicidal Ideators: A longitudinal 6-month follow-up study

BackgroundDespite heterogeneity of older people in suicidal behavior, research identifying characteristics by age groups is scarce. We examined baseline features of older community-dwelling suicidal ideators by dichotomized age groups and the 6-month trajectory of their suicidal ideation along with its related psychopathology. Predictors of suicidal ideation within each group were investigated.MethodsOlder community-dwelling suicidal ideators enrolled in the Korean Cohort for the Model Predicting a Suicide and Suicide-related Behavior study were subdivided into the “young-old (65–74 years)” and “old-old (≥75 years)” group. Baseline, 1-, and 6-month assessments were compared. Within each group, multiple regression analysis using rating scales (Patient Health Questionnaire-9, Beck Anxiety Inventory, Alcohol Use Disorders Identification Test, Stress Questionnaire for Korean National Health and Nutrition Examination Survey-Short Form, and Social Relationships Scale) was conducted to identify predictors of suicidal ideation measured with the intensity subscale of the Columbia-Suicide Severity Rating Scale. Two-way repeated-measures analysis of variance (RM-ANOVA) was used to compare changes in suicidal ideation, depression, anxiety between age groups over time, and one-way RM-ANOVA to examine changes within each age group.ResultsAmong 29 “young-old” and 53 “old-old” ideators, the latter were less likely to be receiving psychiatric treatment (odds ratio [OR] = 4.065) and make suicide attempts (OR = 2.874), whereas the former revealed greater levels of anxiety and stress. Baseline depression and stress in the “young-old” group and the “old-old” group, respectively, predicted the intensity of suicidal ideation at both baseline and 1-month assessments. No significant age group x time interactions on suicidal ideation and depression were found. However, within each age group, both suicidal ideation and depression significantly decreased only during the first month with no further improvement.ConclusionWe speculate cautiously that more attention may need to be paid to the “old-old” ideators in the evaluation of psychiatric issues and for referral to psychiatrists. To decrease suicidal ideation, tailored approaches involving proactive, timely management of depression in the “young-old” and interventions focusing on stress reduction in the “old-old,” would be helpful.
