Psychosocial factors associated with urban adolescent female suicide attempts

This study identified psychosocial factors that differentiated 19 adolescent female suicide attempters from 21 demographically similar nonattempters in a low income, urban area. Adolescents and their parents independently completed questionnaires and participated in structured and semistructured interviews. Attempters expressed significantly higher levels of suicidal ideation and were described by their parents as displaying higher levels of depressed mood and delinquent behavior problems than nonattempters. Attempters also identified fewer support persons, were less likely to be living with their mothers, were less likely to describe confiding relationships with parents/guardians, and had less active and affectionate relationships with mother figures than nonattempters. Finally, attempters reported more undesirable life stresses than nonattempters.     

Moral objections to suicide: Can they counteract suicidality in patients with cluster B psychopathology?

OBJECTIVE: Patients with cluster B personality disorder (CBPD) are particularly prone to suicidal behavior, yet possible protective mechanisms are not often studied. The present study investigated a possible protective role of moral objections to suicide (MOS) against suicidal behavior in patients with CBPD and current depression. The effect of MOS was then examined in relation to other mechanisms affecting suicide risk including trait aggressivity and the presence of effective coping strategies. METHOD: 147 depressed patients with comorbid CBPD (DSM-III-R) were compared with 210 depressed patients without CBPD in terms of their history of suicide attempts and clinical and demographic characteristics. The relationship of MOS to suicide attempt was examined by logistic regression controlling for demographic and clinical differences between the groups as well as presence of comorbid CBPD. Data were collected from 1990 to 2003. RESULTS: Subjects with comorbid CBPD had fewer MOS and reported more previous suicide attempts. In logistic regression, fewer MOS/religious beliefs, lower coping potential, and higher aggression level were associated with suicide attempt. A CBPD diagnosis did not affect the relationship between MOS and suicide attempts. CONCLUSIONS: The results of this study suggest that the presence of MOS/religious beliefs may have a protective effect against suicidal behavior in depressed patients with comorbid CBPD and may be a target for therapeutic intervention.     

Suicide attempts among veterans seeking treatment for pathological gambling

BACKGROUND: There is little information in the scientific literature regarding the suicide attempts of pathological gamblers, even though studies of problem gamblers have found that completed suicide, suicide attempts, and suicidal ideation are common outcomes related to gambling behavior. There has been no attempt in previous studies to identify the contributions of comorbid conditions, such as substance abuse, to the suicide attempts of pathological gamblers. METHOD: A retrospective chart review was completed for all consecutive admissions (N = 114) to the Gambling Treatment Program of the Louis Stokes VA Medical Center over a 12-month period (September 2000-September 2001). All subjects met DSM-IV criteria for pathological gambling. Relevant information was obtained from the admission history and physical examination, as well as a variety of self-report questionnaires and structured instruments. RESULTS: Forty-five patients (39.5%) reported that they had made a suicide attempt at some time in their lives. The most common method was overdose. Sixty-four percent of attempters reported that their most recent attempt was related to gambling. Forty-two percent of gamblers with a history of alcohol dependence and 58.8% of those with a history of drug dependence had a history of suicide attempts. Mean impulsivity scores differentiated suicide attempters from nonattempters among gamblers with a history of drug and/or alcohol dependence. Severity of psychiatric symptoms and family problems on admission was related to a history of suicide attempts. CONCLUSION: Pathological gamblers have high rates of attempted suicide. They are highly impulsive and suffer from high rates of comorbid psychiatric conditions as well as social disruptions. A combination of these risk factors very likely contributes to their potential for suicidal behavior.     

Familial pathways to early-onset suicide attempt: risk for suicidal behavior in offspring of mood-disordered suicide attempters

BACKGROUND: Although adoption, twin, and family studies have shown that suicidal behavior is familial, the risk factors for familial transmission from parent to child remain unclear. METHODS: A high-risk family study was conducted comparing the offspring of 2 mood-disordered groups: suicide attempters and nonattempters. Recruited from 2 sites, probands were 81 attempters and 55 nonattempters, with 183 and 116 offspring, respectively. Offspring were assessed by investigators masked to proband status. Probands and offspring were assessed with respect to psychopathologic findings, suicide attempt history, impulsive aggression, and exposure to familial environmental stressors. RESULTS: Offspring of attempters had a 6-fold increased risk of suicide attempts relative to offspring of nonattempters. Familial transmission of suicide attempt was more likely if (1) probands had a history of sexual abuse and (2) offspring were female and had a mood disorder, substance abuse disorder, increased impulsive aggression, and a history of sexual abuse. CONCLUSIONS: The offspring of mood-disordered suicide attempters are at markedly increased risk for suicide attempts themselves. Familial transmission of suicidal behavior in families with mood disorders almost always requires transmission of a mood disorder and is also related to the offspring's impulsive aggression and the familial transmission of sexual abuse. Early treatment of mood disorders and targeting impulsive aggression and sexual trauma may be helpful in the prevention and treatment of suicidal behavior in families with mood disorders.     

The Additive Effect on Suicidality of Family History of Suicidal Behavior and Early Traumatic Experiences

Family history of suicidal behavior and personal history of childhood abuse are reported risk factors for suicide attempts and suicide completion. We aim to quantify the additive effect of family history of suicidal behavior and different subtypes of childhood abuse on suicidal behavior. We examined a sample of 496 suicide attempters, comparing individuals with family history of suicidal behavior and personal history of childhood (physical or sexual) abuse, individuals with family history of suicidal behavior only, individuals with history of early traumatic experiences only, and individuals with none of these two risk factors with regards to suicidal features. An additive effect was found for the age at the first attempt in suicide attempters with both family history of suicidal behavior and either physical or sexual abuse. No significant interactions were found between family history of suicidal behavior and childhood trauma in relation to any characteristics of suicidal behavior. Subjects presenting family history of suicidal behavior and childhood abuse attempt suicide earlier in life than subjects with just one or none of them, particularly if they were sexually abused. Other suicidality indexes were only partially or not associated with this combination of risk factors. A careful assessment of patients with both family history of suicidal behavior and childhood abuse could help to prevent future suicide attempts, particularly in young people.     

The role of moral objections to suicide in the assessment of suicidal patients

BACKGROUND: Moral and religious objections to suicide (MOS) are reported to be associated with less suicidal behavior in depressed patients, and are proposed to act as a protective factor against suicidal behavior. It is unclear whether MOS are a protective factor against suicide attempt per se, or if this effect is mediated through other variables. METHOD: Depressed inpatients (n=265) reporting low or high MOS were compared on history of suicidal behaviour, demographic and clinical characteristics. RESULTS: Patients with low MOS had significantly more lifetime suicide attempts, were more often without religious affiliation, had greater depression severity, hopelessness and trait impulsivity, less anxiety and fewer reasons for living. Logistic regression revealed that lower MOS was independently associated with suicide attempt. CONCLUSIONS: Moral and religious objections to suicide may serve as a protective factor against suicidal acts given their unique association with less suicidal behavior in depressed inpatients.     

Preliminary report on childhood sexual abuse, suicidal ideation, and suicide attempts among middle-aged and older depressed women.

OBJECTIVE: Authors examined the relationship between childhood sexual abuse histories and suicidal ideation and behavior among depressed women age 50 years and older. METHODS: After admission to a psychiatric unit, participants were administered the Structured Clinical Interview for DSM-III-R and measures of suicidal ideation and behavior. RESULTS: Women who reported abuse histories were more likely to report suicidal ideation at the time of hospitalization and a history of multiple suicide attempts. CONCLUSIONS: These preliminary findings underscore the need for more study of how childhood abuse amplifies risk for suicidal ideation and behavior among women across the life course.     

The Zurich Study: XV. Suicide attempts in a cohort from age 20 to 30

Summary The life-time prevalence of suicide attempts in a Swiss population, interviewed four times between the ages of 20 and 30 years, was 3.8% (females 5.4%, males 2.1%). One fifth of the 30-year-olds reported persistent suicidal ideation. In comparison with controls, attempters reported a more disturbed childhood, and subjects with multiple attempts reported more sexual abuse. Over 10 years attempters persistently showed more negative affectivity, more feelings of helplessness and lower selfesteem. At age 30 they were higher on the scales neuroticism, masculinity and aggressivity in a personality test. Over ten years, a higher than expected comorbidity appeared of suicide attempts with depressive and anxiety disorders, with substance abuse, and with sociopathic features.     

Psychiatric diagnoses in minority female adolescent suicide attempters

Psychiatric diagnoses were examined using the Schedule for Affective Disorders and Schizophrenia for School-Aged Children semistructured interview among three groups of minority adolescent females aged 12 to 17:61 suicide attempters, 31 psychiatrically disturbed nonattempters, and 23 nonattempting, nondisturbed girls. Major or minor depressive disorder was found in 42% of the suicide attempters; conduct disorder in 46%; multiple diagnoses in 38%, no diagnosis in 13%. These rates were very similar to those found in disturbed nonattempters. Only one symptom, suicidal ideation, distinguished attempters from disturbed nonattempters, while many symptoms distinguished these two groups from nondisturbed nonattempters.     

Age and suicidal ideation in older depressed inpatients.

Age-related patterns of symptom presentation may complicate the recognition of suicide risk. The authors sought to determine whether there is a relationship between age and reported suicidal ideation in depressed suicide attempters (DSAs) and depressed nonattempters (DNs) 50 years of age and over. Regression analyses revealed that increasing age is significantly associated with the absence of suicidal ideation in both DSAs and DNs. Because of their lower rates of depressed mood and suicidal ideation, the depressions of older adults may more readily escape detection. Preventive or treatment measures initiated after the onset of the suicidal state may be insufficient, and other preventive strategies ought to be considered.     

Are suicide attempters who self-mutilate a unique population?

OBJECTIVE: Individuals who mutilate themselves are at greater risk for suicidal behavior. Clinically, however, there is a perception that the suicide attempts of self-mutilators are motivated by the desire for attention rather than by a genuine wish to die. The purpose of this study was to determine differences between suicide attempters with and without a history of self-mutilation. METHOD: The authors examined demographic characteristics, psychopathology, objective and perceived lethality of suicide attempts, and perceptions of their suicidal behavior in 30 suicide attempters with cluster B personality disorders who had a history of self-mutilation and a matched group of 23 suicide attempters with cluster B personality disorders who had no history of self-mutilation. RESULTS: The two groups did not differ in the objective lethality of their attempts, but their perceptions of the attempts differed. Self-mutilators perceived their suicide attempts as less lethal, with a greater likelihood of rescue and with less certainty of death. In addition, suicide attempters with a history of self-mutilation had significantly higher levels of depression, hopelessness, aggression, anxiety, impulsivity, and suicide ideation. They exhibited more behaviors consistent with borderline personality disorder and were more likely to have a history of childhood abuse. Self-mutilators had more persistent suicide ideation, and their pattern for suicide was similar to their pattern for self-mutilation, which was characterized by chronic urges to injure themselves. CONCLUSIONS: Suicide attempters with cluster B personality disorders who have a history of self-mutilation tend to be more depressed, anxious, and impulsive, and they also tend to underestimate the lethality of their suicide attempts. Therefore, clinicians may be unintentionally misled in assessing the suicide risk of self-mutilators as less serious than it is.     

Time to emergence of severe suicidal ideation among psychiatric patients as a function of suicide attempt history

BACKGROUND: Little is known about the emergence of suicidal ideation among psychiatric inpatients with histories of no, single, or multiple suicide attempts. We investigated differences in time to reemergence of severe suicidal ideation among psychiatric patients as a function of their suicide attempt histories. METHOD: One hundred seventeen individuals meeting criteria for a major depressive disorder who were recently discharged from a psychiatric hospital and participating in a larger study of treatments for depression were included in the current study. Suicidal ideation, depressive symptoms, hopelessness, and depressogenic cognitions were assessed at baseline, and suicidal ideation was assessed at 3-, 6-, 12-, and 18-month follow-up, as well as inpatient readmission if applicable. Time to the reemergence of severe suicidal ideation was analyzed using survival analysis. RESULTS: Twenty-two percent of our sample reported the occurrence of severe suicidal ideation over an 18-month period. Severe suicidal ideation emerged earlier among patients who had a history of prior suicide attempts than those who did not, but single and multiple suicide attempters did not differ significantly in time to severe suicidal ideation. Suicide attempt history remained a significant predictor of time to severe suicidal ideation when statistically controlling for hopelessness, depressive symptoms, depressogenic cognitions, and suicidal ideation at admission and initial treatment group assignment, especially between single attempters and nonattempters. CONCLUSIONS: Although nearly a quarter of participants endorsed severe, clinically significant suicidal ideation within 18 months of discharge, those with suicide attempt histories reported the occurrence of severe suicidal ideation significantly earlier than those without suicide attempt histories.     

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.     

Suicide attempters in the emergency department before hospitalization in a psychiatric ward

PURPOSE. The study aims to compare the current suicidal risk of mood disorder patients who had just attempted suicide, as compared with those who had not attempted suicide, admitted to an emergency department (ED), and then hospitalized in a psychiatric unit. METHOD. One hundred sixty‐one mood disorder patients admitted to the ED were studied. A total of 22.4% of the participants were admitted for a suicide attempt. Patients were assessed for psychopathology and diagnosis. FINDINGS. Suicide attempters were nearly 12 times more likely to report ongoing suicidal ideation during the psychiatric evaluation in the ED than nonattempters. Men and women did not differ for current and previous suicide attempts or for ongoing suicidal ideation. PRACTICAL IMPLICATIONS. It is important to conduct a suicide risk assessment when individuals are admitted to an ED.     

Association between serotonin transporter gene promoter polymorphism and suicide: results of a meta-analysis.

BACKGROUND: There is strong evidence supporting a role for serotonin system dysfunction in the pathology of suicidal behavior. Many studies have examined the association between a functional polymorphism of the serotonin transporter gene promoter (5-HTTLPR) and suicide but have yielded inconsistent results. Our goal here, by analyzing the cumulative data from primary literature, was to determine conclusively whether there is an association. METHODS: Three meta-analyses were performed. One compared the 5-HTTLPR polymorphism between suicidal subjects and normal control subjects; another compared suicide attempters with nonattempters of the same psychiatric diagnoses; the last one compared either violent or nonviolent suicidal subjects with normal control subjects. RESULTS: We found no association between 5-HTTLPR polymorphism and suicidal behavior (p =.379). When we compared subjects with the same psychiatric diagnoses, the genotypes carrying the s allele were significantly more frequent in suicide attempters than in nonattempters (p =.004). In addition, the s allele was associated with violent suicide (p =.0001) but not with nonviolent suicide (p = 1.00). CONCLUSIONS: Our results provide significant evidence supporting the association of the s allele of 5-HTTLPR polymorphism with suicidal behavior in the psychiatric population, also with violent suicide. These support a role for decreased serotonin transporter function in the vulnerability to suicide in a select population.     

Modeling effects on suicidal behavior

Knowledge of suicidal behavior, i.e., psychiatric patients indicating that they have an acquaintance or relative who has attempted or committed suicide, has been cited as a risk factor in the assessment of suicide potential. The authors evaluated psychiatric patients hospitalized for a suicide attempt (N = 30), serious suicidal ideation (N = 26), or other non-suicide-related reasons (N = 20) and also a control group of 18 patients admitted for orthopaedic surgery. Information derived from a structured clinical interview revealed that suicide attempters have fewer suicidal models than individuals in the other patient groups, and they are more interpersonally distant from the models they do know. Depression level was not positively related to the recall and reporting of suicidal models. Measures assessing suicide-related beliefs revealed that suicide attempters rated suicide as an effective solution for problems to a greater extent that did patients in the remaining three groups. The implications of these results for social learning models of suicidal behavior are discussed.     

A proposed model of the development of suicidal ideations

BackgroundSuicidal ideations may precede suicide attempts. They are of particular concern in psychiatric populations because psychopathology is a major risk factor for suicide. The factors affecting the development of suicide ideations may differ among psychiatric patients with and without a previous suicide attempt and individuals without a psychiatric diagnosis.ObjectivesThe aim of this study is to develop a model of suicide ideation in psychiatric patients and the general population.MethodThe study included 196 participants: 92 psychiatric patients with a previous suicide attempt (“attempters”); 47 psychiatric patients who had never attempted suicide (“non-attempters”); and 57 healthy control subjects. Data were collected on socio-demographic parameters, clinical history, and details of the suicide attempts. Participants completed a battery of psychological instruments assessing aggression–impulsivity, mental pain (including depression and hopelessness) and communication difficulties, in addition to negative life events. Findings were correlated with suicidal ideation by group.ResultsThe correlations of the different variables with suicidal ideation differed between suicide attempters and non-attempters; therefore, the model was analyzed separately for each group. The study yielded three major findings: negative life events had a significant effect on both anger-in and impulsivity in non-attempters but not in attempters; hopelessness moderately contributed to suicidal ideations in attempters but not in non-attempters; loneliness contributed significantly to depression in non-attempters but was less distressing in attempters.ConclusionThe mechanism underlying suicidal ideation appears to differ between psychiatric patients who have previously attempted suicide and those who have not, supporting a dual model of suicidal ideation. Although this is only a preliminary study, these findings are important for furthering our understanding of the process of transition of suicidal thoughts to completion of suicide. These results need further replication with a larger cohort of subjects.     

Suicidality in eating disorders: clinical and psychological correlates

Although many authors have described eating disorders as often being associated with suicidal feelings and behaviour, few studies to date have evaluated the prevalence and characteristics of suicidal behaviour in eating disordered patients. In the present study, in which a consecutive series of 495 out-patients was studied, 13% of the patients reported at least one suicide attempt and 29% reported current suicidal ideation; 26% of attempters reported multiple attempts. A history of suicide attempt was more prevalent among binge-eating/purging anorexics and among purging bulimics than in the other subgroups. In cases with anorexia nervosa, suicide attempters were older, had a longer illness duration, weighed less, had more often used drugs and/or alcohol and tended to be more obsessive than non-attempters. In cases with bulimia nervosa, attempters presented with more psychiatric symptoms and had more frequently been sexually abused.     

Protective factors against suicidal behavior in Latinos

Latinos appear to be relatively protected against suicidal behavior, but the factors that mediate this effect are not known. Some protective factors may be related to cultural constructs that provide a buffer against suicidal behavior in the face of psychiatric illness. We sought to determine whether the Reasons for Living Inventory (RFLI) might capture protective factors against suicidal behavior in Latinos and non-Latinos. Patients with major depression, bipolar disorder, or schizophrenia were interviewed regarding their depressive symptomatology and lifetime history of suicidal behavior. The RFLI, which measures protective factors against suicidal acts, was also administered. Multivariate analyses were used to assess the relationship between suicide measures, ethnicity, and selected clinical and demographic variables. Although Latinos and non-Latinos did not differ significantly in attempter status (attempter/nonattempter), number of attempts, or suicide intent, Latinos reported significantly less suicidal ideation and made less lethal attempts. On the RFLI, Latinos scored significantly higher on subscales regarding survival and coping beliefs, responsibility to family, and moral objections to suicide, possibly reflective of cultural norms endorsed by Latino groups. Multivariate analyses suggested that although being Latino was independently associated with less suicidal ideation, other suicidal behaviors held a stronger relationship to moral objections to suicide and survival and coping skills than to ethnicity. Self-identification as Latino may be associated with espousing cultural constructs that mediate protective effects against suicidal behavior. Constructs identified in the RFLI may protect Latinos from acting on suicidal thoughts, affecting moral objections to suicide and survival and coping beliefs. Further studies to elucidate the impact of these factors on suicidal behavior and their relationship to specific cultural constructs would be of interest.     

Psychiatric Diagnoses and Comorbidity in Relation to Suicidal Behavior Among Psychiatrically Hospitalized Adolescents

This study examined relations between suicidal behavior history (i.e., no suicidality, suicidal ideation, single attempters, and multiple attempters) and psychiatric functioning. Adolescents, aged 12-17, admitted to an inpatient psychiatric unit, were categorized by suicidal behavior history based on self- and clinician-report data. Groups were examined for differences in suicidal ideation and psychiatric diagnosis. Severity of suicidal ideation increased with severity of suicidal behavior history. Females were disproportionately represented among multiple attempters. Multiple attempters were more likely to be diagnosed with at least one externalizing disorder, particularly substance use disorders, and to have more than one comorbid diagnosis than adolescents with no suicidal behavior or a history of ideation only. Clinicians should be alerted to the particularly high-risk nature of adolescents with multiple suicide attempts.
