Relationship of childhood trauma to age of first suicide attempt and number of attempts in substance dependent patients

OBJECTIVE: To examine whether childhood trauma effect the age of first attempting suicide and the number of attempts. METHOD: One thousand twelve hundred and eighty substance dependent patients were interviewed about whether or not they had ever attempted suicide, the age of first attempt and the number of attempts. Patients completed the Childhood Trauma Questionnaire - 34 item version. RESULTS: Five hundred and thirty-eight patients (42%) had attempted suicide. Significantly more of the patients who had attempted suicide were female. Patients who had made three or more attempts had significantly higher childhood trauma scores than patients who had made two attempts, who had higher scores than patients who had made one attempt, who had higher scores than patients who had never attempted. Patients who first attempted suicide before the age of 20 years had significantly higher childhood trauma scores than patients who first attempted after 20 years of age. CONCLUSION: Childhood trauma may be a determinant of the age of onset of suicidal behavior and of the number of suicide attempts.     

Incarceration associated with homelessness, mental disorder, and co-occurring substance abuse

OBJECTIVE: This study assessed relationships between homelessness, mental disorder, and incarceration. METHODS: Using archival databases that included all 12,934 individuals who entered the San Francisco County Jail system during the first six months of 2000, the authors assessed clinical and behavioral characteristics associated with homelessness and incarceration. RESULTS: In 16 percent of the episodes of incarceration, the inmates were homeless, and in 18 percent of the episodes, the inmates had a diagnosis of a mental disorder; 30 percent of the inmates who were homeless had a diagnosis of a mental disorder during one or more episodes. Seventy-eight percent of the homeless inmates with a severe mental disorder had co-occurring substance-related disorders. Inmates with dual diagnoses were more likely to be homeless and to be charged with violent crimes than other inmates. Multiple regression analyses showed that inmates who were homeless and had co-occurring severe mental disorders and substance-related disorders were held in jail longer than other inmates who had been charged with similar crimes. CONCLUSIONS: People who were homeless and who were identified as having mental disorders, although representing only a small proportion of the total population, accounted for a substantial proportion of persons who were incarcerated in the criminal justice system in this study's urban setting. The increased duration of incarceration associated with homelessness and co-occurring severe mental disorders and substance-related disorders suggests that jails are de facto assuming responsibility for a population whose needs span multiple service delivery systems.     

Suicidal ideation and suicide attempts in a sample of homeless people with mental illness

This study utilized data from the national ACCESS program (N = 7224) to investigate the prevalence of suicidal ideation and suicide attempts in a sample of homeless people with mental illness. The prevalence of suicidal ideation in this sample was high (66.2% lifetime prevalence). In addition, 51.3% of the sample reported that they had ever attempted suicide, 26.9% reported an attempt that resulted in a nonpsychiatric hospitalization, and 8% reported an attempt in the previous 30 days. Youth, substance abuse, and psychiatric symptoms were all significantly associated with suicide attempts. Those who reported a recent attempt also reported higher rates of mental health care utilization, particularly inpatient care. The authors conclude that homeless people with mental illness are at particularly high risk for suicidal behavior, however, only in part because of the high prevalence of traditional risk factors.     

The relevance of suicidal behaviour in jail and prison suicides.

PURPOSE: Suicide rates in correctional institutions have been increasing during the last decades. There has been little interest in whether suicidal ideation and intent has been documented by non-medical prison staff (reports of attempted suicide, suicide threats, self-harm), and whether these signs of suicidality had the consequence of adequate intervention efforts. METHODS: The personal files of inmates who committed suicide in the 29 Austrian jails and prisons during the last 25 years (1975-1999) were included. We analysed personal characteristics, criminological data, circumstances of custody and information about psychiatric disorders and treatment. RESULTS: Of a total of 250 suicides, 220 personal files were available and included. Suicide attempts were known in 50% of all suicides and 37% had expressed suicidality. In >20%, non-medical staff had documented signs of suicidality, but no further preventive action (e.g. referral to psychiatric care) had taken place. CONCLUSION: Signs of suicidality play an important role in vulnerability profiles for jail and prison suicides and should have the minimal consequence of further psychiatric care.     

Clinical characteristics of adolescent psychiatric inpatients who have attempted suicide

 The clinical characteristics of 191 adolescent inpatients were examined in relation to frequency of previous suicide attempts, predictors of suicide attempts prior to hospitalization, and lifetime suicide attempts. Overall, more than 50% of the adolescent inpatients had attempted suicide during their lifetime, and of these more than half (58%) had made more than one attempt. Approximately half of the suicide attempters had made a serious attempt prior to hospitalization. Girls reported higher levels of depressive symptoms and suicidal ideation than boys, in addition to having attempted suicide prior to hospitalization (33%) or during lifetime (37%) more often than the boys (13% and 26%, respectively). Although about two thirds of the adolescent inpatients reported that they had received some help after a suicide attempt, approximately half of the repeaters had not received any help. The results of multivariate analyses showed that suicide attempts made prior to hospitalization were predicted by depressive symptom levels and a clinical diagnosis of depressive disorder, whereas frequency of lifetime suicide attempts was predicted by suicidal ideation levels and having a family member or a friend who had attempted (or committed) suicide. The high prevalence of lifetime and repeated suicide attempts among the psychiatric inpatients underscores the importance of identifying risk factors in the clinical evaluation of adolescent suicide attempters.

Suicide attempts and ideation in patients with bipolar I disorder

BACKGROUND: Suicidal thinking and behavior are common in individuals with bipolar disorder. METHOD: Suicidal ideation and suicide attempts were examined in 175 patients with bipolar I disorder (diagnosis confirmed with the Schedule for Affective Disorders and Schizophrenia or the Structured Clinical Interview for DSM-IV) participating in the Pittsburgh Study of Maintenance Therapies in Bipolar Disorder. Patients who attempted suicide before entering the study were compared with those who did not attempt suicide with respect to clinical and demographic characteristics. RESULTS: Twenty-nine percent of the patients had attempted suicide prior to entering the study. Suicide attempts happened at a relatively young age and in the first period of the illness. Greater severity of bipolar disorder, as indicated by a greater number of previous depressive episodes (p =.0009) and higher HAM-D-25 scores (p =.04), and higher body mass index (p =.03) were significantly correlated with a history of suicide attempts. None of the patients with a history of suicide attempt attempted suicide again. However, 5 patients without a history of suicide attempt did attempt suicide. Four of these patients did not display severe suicidal ideation at the assessment that preceded the suicide attempt. No subject completed suicide during the 11 years of the study. CONCLUSION: Greater severity of bipolar disorder and higher body mass index are significantly correlated with a history of suicide attempts. However, a treatment program in a maximally supportive clinical environment can reduce suicidal behavior in high-risk patients. In some cases, suicide risk is transient and may be preceded by a period of severe suicidal ideation that lasts only a few minutes or hours. In such cases, mental health professionals are unable to predict suicide attempts.     

Variables associated with hospitalization decisions by emergency psychiatrists after a patient's suicide attempt

OBJECTIVE: This study explored the factors psychiatrists considered in deciding on hospitalization for a large sample of suicide attempters in the emergency department of a general hospital in Madrid, Spain, between 1996 and 1998. METHODS: Psychiatrists assessed 509 patients who had attempted suicide; 196 of these (39 percent) were hospitalized in the psychiatric unit, and 313 (61 percent) were discharged from the emergency department. The assessment included Beck's Suicidal Intent Scale (SIS) and a checklist of 47 clinical variables. RESULTS: Of the 32 clinical variables significantly associated with hospitalization that were introduced in a logistic regression model, 11 remained significant. Six variables were associated with an increased odds of hospitalization: intention to repeat the attempt, plan to use a lethal method, low psychosocial functioning before the suicide attempt, previous psychiatric hospitalization, a suicide attempt in the past year, and planning that nobody would try to save their life after they had attempted suicide. Five variables decreased the odds: a realistic perspective on the future after the attempt, relief that the attempt was not effective, availability of a method to kill oneself (that was not used), belief that the attempt would influence others, and family support. Models based on the SIS total score and individual SIS items had lower specificity and sensitivity. CONCLUSIONS: Psychiatrists appear to rely on patients' self-report in deciding on hospitalization rather than focus on demographic, diagnostic, or psychosocial issues. If the findings of this study were replicated in other hospital settings, the implication would be that the guidelines for assessing suicide attempts need to encourage thorough and detailed assessment of the attempt and the future plans.     

Mortality and further suicidal behaviour after an index suicide attempt: a 10-year study

OBJECTIVE: To examine further suicide attempts and mortality in the 10 years after a suicide attempt requiring hospital admission. METHOD: Participants were a consecutive series of 3690 individuals admitted to Christchurch Hospital for attempted suicide during the 10-year period 1993-2002. Data were obtained on admissions to Christchurch Hospital for attempted suicide during the study period. Mortality subsequent to the index suicide attempt was established from the National Mortality Database. The influence of age, gender and method of index suicide attempt on mortality and further suicide attempts requiring hospitalization were examined. RESULTS: Within 10 years, 28.1% of those who had been admitted for an index suicide attempt were readmitted for a further non-fatal suicide attempt, and 4.6% died by suicide. Risks and rates of readmission were higher in: females; those under 55; and those whose index attempt involved a method of low lethality. Risks and rates of suicide were higher in: males; those aged 25 and over; and those using an index suicide attempt method of high lethality. Risks and rates of readmission and mortality from suicide were highest in the first 2 years after the index attempt, although deaths and readmissions occurred throughout the 10 years study period. CONCLUSIONS: Those making suicide attempts requiring hospital admission are at high risk of further hospitalization for suicide attempt and of death from suicide. These findings suggest a need for ongoing support and monitoring, and for enhanced treatment and management of all those making suicide attempts which require hospital admission in an effort to reduce risks of further suicidal behaviour.     

Risk of suicide after attempted suicide in the population of Slovenia from 1970 to 1996.

OBJECTIVE: All suicide attempts cannot predict suicide, therefore we examined those characteristics of suicide attempt which could most accurately predict completed suicide. SUBJECT AND METHODS: Subjects were all individuals registered as committed suicides (N=16,522) or attempted suicides (N=15,057) in the register of suicides of the Republic of Slovenia between 1970 and 1996. Log linear analysis of a frequency table was used to uncover relationship between categorical variables. RESULTS: The model we found fit between variables: mode, number of repetitions and type, then between number of repetitions, type and gender, and between mode, type and gender. DISCUSSION: The risk of suicide in those who previously attempted suicide is approximately 773 times higher than the risk of suicide without a previous suicide attempt. Those who attempt suicide by hanging (hanging being in Slovenia the most frequent mode of completed suicide) are at even greater risk to commit suicide. CONCLUSION: Our data suggests that clinicians should heighten their awareness that any suicide attempt can in some 20% predict suicide. Someone who has attempted suicide by hanging is at the highest risk of suicide.     

A model for the provision of jail mental health services: an integrative, community-based approach

Although a considerable amount of attention has been paid to the development and implementation of mental health services in prisons, relatively little work has focused on the provision of such services to jails. Jails generally serve two purposes: (1) they hold inmates awaiting arraignment or trial and (2) they serve as short-term correctional facilities for individuals who have been assigned relatively short sentences (no longer than one or two years). Because inmnates in the first category usually remain in jail for a short period of time, it is particularly challenging to provide them mental health services. This article describes an innovative program that has recently been developed for assessing the mental health needs of inmates awaiting arraignment or trial, and providing them with mental health services.     

Suicide, attempted suicide, and relapse rates in depression

Suicide, attempted suicide, and relapse rates in 519 depressives were examined, comparing the effects of different treatments. After six months, suicide attempts were seen significantly less frequently in the ECT groups (0.8%) than in the antidepressant group (4.2%) or the "adequate" antidepressant subgroup (7.0%) Fewer suicide attempts occurred in the ECT group compared to the antidepressant group among both in those who had attempted suicide prior to admission (0% vs 10%) and in those who had not (1.1% vs 3.6%). A history of attempted suicide showed a greater risk of both suicide (2.9%) in the following year and subsequent suicide attempt (5.9%). A depressive diagnosis may be as good a predictor of suicidal behavior as a history of attempted suicide. Relapse rates did not differ between treatment groups.     

Attempted suicide predicts suicide risk in schizophrenia spectrum psychosis

Background: People with schizophrenia have an increased risk of suicide and attempted suicide is suggested to be an important risk factor. Aim: Our objective was to assess the cumulative survival, predictive values and odds ratios of attempted suicide for suicide in a long-term cohort of patients with schizophrenia spectrum psychosis with and without previous attempted suicide. Method: Inpatients (n=224) hospitalized with schizophrenia spectrum psychosis were followed for a mean of 25 years. All patients were followed up for causes of death. Information on suicide attempt before the end of the observation period was retrieved from medical records. Results: Eight percent died by suicide during the follow-up. Eighteen percent of suicide attempters died by suicide. Two percent of non-attempters died by suicide. There was a strong association between previous suicide attempt and suicide in men and women. Odds ratio for attempters vs. non-attempters was 10. Suicide risk was almost three times higher in male than female suicide attempters. Conclusion: Previous attempted suicide is an important risk factor for suicide in both men and women with schizophrenia spectrum psychosis, particularly in male suicide attempters. The suicide risk remains high over a long period. Continuous assessment of risk factors and appropriate treatment are crucial for this patient group to prevent suicide.     

Characteristics of Recent Suicide Attempts by Inmates in Maximum Security Correctional Centers

The research examined inmates' subjective perceptions of the reasons for suicide attempts and the psychological, sociological and criminological factors associated with such attempts. The sample comprised 60 male inmates who had made a recent suicide attempt. The methods of examination were semi-structured interviews with the inmates and analysis of their psychological and criminological files. The results showed that the examined group was not totally homogeneous. Methods of suicidal attempts divided the sample into two groups: those who had made a non-life-threatening (NLT) suicide attempt (58%) and those who made a life-threatening (LT) attempt (42%). Several factors significantly differentiated NLT and LT groups. Four of these factors were combined in regression models to clarify the relationships between the variables and to predict, in retrospect, whether an inmate had made a NLT or LT suicide attempt. The results are discussed in relation to previous findings on suicidology and to practical implications in correctional settings.     

Repetition of attempted suicide among teenagers in Europe: frequency, timing and risk factors

Background. Adolescents in many countries show high rates of suicide attempts and repetitions of attempts as a common feature. Attempted suicide is the best predictor of future suicide. Repetition of attempts further increases the risk of suicide. The present study sought to identify patterns and risk factors for repetition of attempts in older teenagers. Methods. Data were collected by uniform procedures in a longitudinal follow-up study in seven European centres participating in the WHO/EURO Multicentre Study on Suicidal Behaviour. Information on attempted suicide in the 15–19-year age group during the period 1989–1995 was analysed. Results. A total of 1,720 attempts by 1,264 individuals over a mean follow-up period of 204 weeks (SD 108.9) were recorded. When life-table analysis was performed, 24 % of the individuals who had previously attempted suicide made another attempt within one year after the index attempt, compared with 6.8 % of the “first-evers”, with no major gender difference. Cox regression analysis revealed that previous attempted suicide (OR 3.3, 95 % CI 2.4–4.4) and use of “hard” methods (OR 1.5, 95 % CI 1.1–2.1) were both significantly associated with repetition of attempted suicide. Stepwise Cox regression analysis showed that a history of previous attempted suicide was the most important independent predictor of repetition (OR 3.2, 95 % CI 2.4–4.4). Conclusion. For young suicide attempters, follow-up and adequate aftercare are very important if repetition and risk of suicide are to be reduced. This applies particularly to those who have already made more than one attempt. Accepted: 19 February 2001     

Validation of the brief jail mental health screen

OBJECTIVE: Jails have a substantial legal obligation to provide health and mental health care for inmates; yet screening procedures across American jails are highly variable. Currently, no valid, practical, standardized tool is available. The study reported here sought to validate a revision of the Referral Decision Scale (RDS)--the Brief Jail Mental Health Screen (BJMHS)--which provides an even briefer and more practical tool for use in jails. METHODS: Valid BJMHS data were collected in four jails (two in Maryland and two in New York) from 10,330 detainees. A total of 357 detainees were also administered the Structured Clinical Interview for DSM-IV (SCID) for standardized clinical cross-validation: 125 detainees (74 men and 51 women) who were classified as referrals for further mental health assessment on the basis of BJMHS and 232 detainees (137 men and 95 women) who were not classified as referrals. RESULTS: The BJMHS takes an average of 2.5 minutes to administer. It correctly classified 73.5 percent of males but only 61.6 percent of females on the basis of SCID diagnoses. Overall, the BJMHS identified 11.3 percent of screened detainees for further mental health assessment. CONCLUSIONS: The BJMHS is a practical, efficient tool that jail correction officers can give male detainees on intake screening. However, the screen has an unacceptably high false-negative rate for female detainees.     

Health care contacts before and after attempted suicide

Objective The prevalence and timing of contact with health care predicting and after a suicide attempt are not well known. This study systematically investigated the pattern of all health care contacts both before and after attempted suicide. Methods All consecutive 1,198 suicide attempters treated in hospital emergency rooms in Helsinki during a 12-month period were identified. Data were gathered on all health care contacts 1 year before and after the index attempt. Results The vast majority of the suicide attempters had contact with health care during the 12 months before and after the index attempt. However, half were without a treatment contact during the final 30 days before the index attempt and one-third in the 30 days following the attempt. Suicide attempters who were not referred to aftercare, did not suffer from a previously recognised major mental disorder, were male, or made non-violent attempts were less likely to be receiving treatment after the attempt. Conclusion Although most suicide attempters have contact with health care within the year before and after the parasuicide, far fewer actually have a treatment contact at the time of the attempt.

Risk of repetition of suicide attempt, suicide or all deaths after an episode of attempted suicide: a register-based survival analysis

OBJECTIVE: This study was undertaken in order to estimate the incidence of repetition of suicide attempt, suicide and all deaths, and to analyse the influence of psychiatric illness and socio-demographic factors on these. METHOD: The study is a Danish register-based survival analysis that retrieved personal data on socio-economic, psychiatric and mortality conditions from various registers. Hazards were estimated using Cox regression with a time-dependence covariate. Suicide-attempters (2.614) and non-attempters (39.210)were analysed being matched by gender, age and place of residence. RESULTS: The average follow-up period for suicide-attempters was 3.88 years, during which 271 (10.37%) of them died. By comparison, death occurred four times more often among suicide-attempters than among non-attempters. Suicide was far more common among attempters (61, 2.33%) than among non-attempters (16, 0.04%). A proportion of the attempters (31.33%) repeated their attempt within the follow-up period. The most reliable predictors for suicide and death were repetition, suicide attempt method and treatment for mental illness. The most reliable predictors for repetition were age, gender and mental illness. DISCUSSION: Individuals with a history of suicide attempts form a well-defined high-risk group for suicide, and are in need of treatment immediately after the episode. Somatic and psychiatric staff must be informed about the risk factors for subsequent suicidal behaviour after an episode of attempted suicide. Furthermore, departments that are in contact with suicidal individuals need action plans to ensure that all such individuals are discharged to proper treatment immediately after the suicide attempt.     

Nonsuicidal self-injury as a prospective predictor of suicide attempts in a clinical sample of military personnel

BackgroundNonsuicidal self-injury (NSSI) is a risk factor for suicide attempts, but it has received little attention in military populations, for whom suicide rates have doubled over the past decade. In the current study, the relationship of NSSI with future suicide attempts was prospectively examined in a sample of active duty Soldiers receiving outpatient psychiatric treatment for suicide ideation and/or a recent suicide attempt.MethodsData were collected as part of a two-year prospective study of 152 active duty Soldiers (87% male, 71% Caucasian, mean age = 27.53) in outpatient mental health care who reported current suicide ideation and/or a suicide attempt during the month preceding intake. Suicide attempts and NSSI were assessed using the Suicide Attempt Self Injury Interview.ResultsForty percent of Soldiers with a history of nonsuicidal self-injury and 25% of Soldiers with a history of suicide attempt made a suicide attempt during the 2-year follow-up. Soldiers with a history of nonsuicidal self-injury were more than twice as likely to make a subsequent suicide attempt (hazard ratio [HR] = 2.25, P = .045). Soldiers with a history of suicide attempt were no more likely to make a subsequent suicide attempt than Soldiers without a previous suicide attempt (HR = .88, P = .787). Thirty percent of Soldiers with a history of suicide attempt had also engaged in nonsuicidal self-injury. Forty-two percent of Soldiers with histories of both nonsuicidal self-injury and suicide attempt made a subsequent suicide attempt and were more likely to make a suicide attempt during follow-up than Soldiers with a history of suicide attempt only. Number of NSSI episodes, but not number of suicide attempts, was significantly associated with increased risk for future suicide attempt. Results were unchanged when adjusting for baseline symptom severity.LimitationsPredominantly male, active duty Army sample.ConclusionsAmong Soldiers in outpatient mental health care, a history of NSSI is a stronger predictor of future suicide attempts than a history of suicide attempts. Soldiers with a history of both NSSI and suicide attempt are at especially increased risk.     

Suicidal children grow up: demographic and clinical risk factors for adolescent suicide attempts

This longitudinal study reports rates and demographic and clinical risk factors for adolescent suicide attempts during a 6- to 8-year follow-up period of an initial sample of 106 preadolescent and young adolescent psychiatric inpatients and 101 preadolescent and young adolescent nonpatients. Survival analysis was used to evaluate risk for a first suicide attempt in the follow-up period for 133 subjects who were interviewed. No deaths occurred. Suicidal inpatients, compared with nonpatients, had earlier first suicide attempts in the follow-up period. Adolescents who attempted suicide in the follow-up period were seven times more likely to have a mood disorder during the follow-up period than those who did not attempt suicide. Implications for clinical practice and research are discussed.     

Suicide attempts in schizophrenia: the role of command auditory hallucinations for suicide

BACKGROUND: We examined the presence of command auditory hallucinations for suicide (CAHS) in a sample of individuals with schizophrenia or schizoaffective disorder. We examined the relationship between CAHS and demographic and clinical variables. We also investigated the relationship between CAHS and suicide attempts. METHOD: 100 individuals with DSM-IV schizophrenia or schizoaffective disorder hospitalized on an inpatient research unit participated. Information was gathered using the Diagnostic Interview for Genetic Studies and the Harkavy Asnis Suicide Scale. Data were gathered from 1995 to 2001. RESULTS: CAHS were frequent in this sample (22%), as were suicide attempts (33%). Eight percent of the entire sample (36% of those who experienced CAHS) made at least 1 suicide attempt in response to the hallucinations. The presence of CAHS was not related to demographic or clinical measures assessed. The frequency of CAHS was not statistically different for suicide attempters (30%) and nonattempters (18%). However, 80% (8/10) of attempters with CAHS reported at least 1 attempt in response to CAHS. Three of 6 repeat attempters who made at least 1 suicide attempt in response to CAHS also made other attempts that were not in response to CAHS. The presence of CAHS was not associated with a history of depression or substance abuse/dependence. CONCLUSION: The presence of CAHS does not directly predict suicide attempts. However, individuals who are already at risk for suicidal behavior (e.g., past attempters) may be at increased risk for a suicide attempt when experiencing CAHS.
