Anxiety disorders in suicidal youth.

OBJECTIVE: To test the hypothesis that anxiety disorders are associated with suicidal ideation and suicide attempts in a child and adolescent sample referred to a clinic. METHOD: The sample comprised 1979 patients aged 5 to 19 years who were assessed using the Schedule for Affective Disorders and Schizophrenia for School Aged Children--Present Episode (K-SADS-P) at an outpatient mood and anxiety disorders clinic. Subjects were stratified by age and categorized into mutually exclusive groups as being nonsuicidal (n = 817), having suicidal ideation (n = 768), or having attempted suicide (n = 394) in the current episode. Psychiatric diagnoses based on DSM-IV criteria were compared to determine if anxiety disorders were a risk factor for suicidal ideation and suicide attempts. Logistic regression was used to control for significant demographic characteristics and comorbid disorders. RESULTS: After stratifying by age, we found no differences across the 3 groups (ideators, attempters, and nonsuicidal youth) in rates of an anxiety disorder in general or in specific rates of panic disorder, agoraphobia, social phobia, simple phobia, and obsessive-compulsive disorder. Two salient findings involving anxiety disorders were noted with regression analysis. In younger children (age < or = 15 years), attempters had a significantly lower prevalence of separation anxiety disorder (SAD), compared with ideators (OR = 0.30; 95%CI, 0.11 to 0.80; P = 0.006) and nonsuicidal youngsters (OR = 0.14; 95%CI, 0.05 to 0.39; P < 0.0001). In older children (age > 15 years), generalized anxiety disorder (GAD) was more prevalent in ideators (OR = 1.65; 95%CI, 1.03 to 2.66; P = 0.03) than in nonsuicidal patients. CONCLUSIONS: Based on this clinical sample, the relation between pediatric anxiety disorder and suicidal ideation and suicide attempts is not straightforward. However, further studies in nonreferred samples are warranted.     

Prevalence of subthreshold forms of psychiatric disorders in persons making suicide attempts in Hungary.

BACKGROUND: Suicide and suicide attempts have been associated to psychiatric illnesses; however, little is known about the role in suicide risk of those symptoms that do not meet the full criteria for a DSM-IV disorder. The aim of this study was to examine the prevalence of subthreshold psychiatric disorders among suicide attempters in Hungary. METHODS: Using a modified structured interview (Mini International Neuropsychiatric Interview) determining 16 Axis I psychiatric diagnoses and their subthreshold forms defined by the DSM-IV and a semistructured interview collecting background information, the authors examined 140 consecutive suicide attempters, aged 18-65 years. RESULTS: Eighty-three-point-six percent of the attempters had one or more current threshold diagnoses on Axis I and in addition more than three-quarters (78.6%) of the subjects had at least one subthreshold diagnosis. Six-point-four percent of the subjects (N = 9) had neither subthreshold nor threshold diagnoses at the time of their suicide attempts. Ten percent of the subjects (N = 14), not meeting the full criteria for any DSM-IV diagnoses, had at least one subthreshold diagnosis. In 68.6% of the subjects (N = 96), both subthreshold and threshold disorders were diagnosed at the time of their suicide attempts. The number of subthreshold and threshold diagnoses were positively and significantly related (chi2 = 5.12, df = 1, P < 0.05). Sixty-three-point-six percent of the individuals received two or more current threshold diagnoses on Axis I and 44.3% of the individuals (N = 62) had two or more subthreshold diagnoses at the time of their suicide attempts. LIMITATIONS: The subthreshold definitions in this study included only those forms of the disorders which required the same duration as the criteria DSM-IV disorder with fewer symptoms. Conclusions - Suicide attempts showed a very high prevalence of subthreshold disorders besides psychiatric disorders meeting the full criteria required according to the DSM-IV. Subthreshold forms of mental disorders need to be taken into account in suicide prevention.     

Characteristics of first suicide attempts in single versus multiple suicide attempters with bipolar disorder

Although suicidality remains highly prevalent among patients with bipolar disorder, little research exists examining the characteristics of successive attempts among individuals who make and survive a first suicide attempt. We compared bipolar subjects with a history of one suicide attempt to those with multiple attempts and assessed demographic characteristics, family histories, psychopathology, and clinical dimensions of suicidal behavior. Fifty-two DSM-IV bipolar patients (age 21 to 74 years) with a history of at least one suicide attempt were consecutively evaluated in the Bipolar Disorders Research Clinic of the New York Presbyterian Hospital. Circumstances surrounding each lifetime suicide attempt were assessed by direct interviews, questionnaires, and chart reviews along with family psychiatric histories, substance abuse histories, current psychopathology, and features of impulsivity and aggression. Multiple suicide attempts occurred in approximately two thirds of the study group. Single attempters were significantly more likely than multiple attempters to show high seriousness of intent at their first attempt (OR = 0.65, 95% CI = 0.43 to 0.99), and tended to be less likely than multiple attempters to exhibit mixed states at their first attempt (OR = 0.54, 95% CI = 0.28 to 1.01). Seriousness of intent was consistent across the first and second attempts (r =.48, P <.01) and second and third attempts (r =.74, P <.05). Single and multiple attempters differed in no other clinical or demographic characteristics studied. We conclude that multiple suicide attempts are common among bipolar patients. Those who survive an initial suicide attempt involving high seriousness of intent appear less likely than those with low intent to make subsequent attempts. Consequently, single attempters may represent a group more closely resembling those who complete suicide on a first attempt, in terms of the risk for death associated with their first attempt. However, multiple suicide attempts among bipolar patients are not necessarily associated with a higher risk for lethality in first suicide attempt survivors.     

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.     

Gender differences in adolescents and young adults with suicidal behaviour.

OBJECTIVE: Gender differences in prevalence rates of suicide attempts and suicidal thoughts as well as in risk factors for suicide attempts such as traumatic events and mental disorders were investigated in a random sample of 3021 adolescents aged 14-24 years. METHOD: The M-CIDI (Composite International Diagnostic Interview) was used to survey suicidal behaviour, DSM-IV lifetime diagnoses and traumatic events. RESULTS: The female suicide attempters showed suicidal thoughts and suicide attempts significantly more often, and suicide attempts at a much younger age than the males. Furthermore, the females experienced sexual abuse much more often, and suffered significantly more often from anxiety disorders. The male suicide attempters showed higher rates of alcohol disorders and financial problems. CONCLUSION: A higher rate of anxiety in female suicide attempters results probably as a consequence of sexual abuse, which in turn makes them more vulnerable than males for attempting suicide between the age of 14-17.     

Depressed Suicide Attempters with Posttraumatic Stress Disorder

Posttraumatic stress disorder and major depressive disorder are well-established risk factors for suicidal behavior. This study compared depressed suicide attempters with and without comorbid posttraumatic stress disorder with respect to additional diagnoses, global functioning, depressive symptoms, substance abuse, history of traumatic exposure, and suicidal behavior. Adult patients consecutively admitted to a general hospital after a suicide attempt were interviewed and assessed for DSM-IV diagnosis and clinical correlates. Sixty-four patients (71%) were diagnosed with depression; of them, 21 patients (32%) had posttraumatic stress disorder. There were no group differences in social adjustment, depressive symptoms, or suicidal intent. However, the group with comorbid depression and posttraumatic stress disorder had more additional Axis I diagnoses, a higher degree of childhood trauma exposure, and more often reported previous suicide attempts, non-suicidal self-harm, and vengeful suicidal motives. These findings underline the clinical importance of diagnosis and treatment of posttraumatic stress disorder in suicide attempters.     

A history of major depressive disorder influences intent to die in violent suicide attempters

BACKGROUND: The inconsistency of the results obtained in biological studies of suicidal behavior may be due to the use of broad categories lacking validity. In previous genetic studies, in which we identified an association between a serotonin-related gene and violent suicide attempts, we suggested that a history of major depressive disorder (MDD) might influence this association. In this study, we aimed to clarify the relationships between the violence of suicide attempts, intent to die, and depression in a large sample of suicide attempters. METHOD: We investigated intent to die, according to history of violent suicide attempts and MDD, in 502 consecutively admitted suicide attempters. We characterized patients in terms of lifetime DSM-IV Axis I diagnoses, suicidal intent (Beck Suicide Intent Scale), and history of violent suicide attempts. RESULTS: Suicidal intent, for both the last suicide attempt before admission and the most lethal suicide attempt, was higher in those with history of MDD (p =.03 and p =.04, respectively) but was not affected by history of violent suicide attempt. In violent suicide attempters, suicidal intent was higher in patients with a history of MDD than in patients with no such history (p =.04 for last suicide attempt and p =.02 for most lethal attempt), whereas MDD had no effect on suicidal intent in nonviolent suicide attempters. CONCLUSION: Violent suicide attempters constitute a heterogeneous group in terms of suicidal intent. Our results suggest that biological and genetic studies should take into account the method used to attempt suicide, intent to die, and history of MDD.     

Bipolar disorder with comorbid cluster B personality disorder features: impact on suicidality

BACKGROUND: Because of their overlapping phenomenology and mutually chronic, persistent nature, distinctions between bipolar disorder and cluster B personality disorders remain a source of unresolved clinical controversy. The extent to which comorbid personality disorders impact course and outcome for bipolar patients also has received little systematic study. METHOD: One hundred DSM-IV bipolar I (N = 73) or II (N = 27) patients consecutively underwent diagnostic evaluations with structured clinical interviews for DSM-IV Axis I and cluster B Axis II disorders, along with assessments of histories of childhood trauma or abuse. Cluster B diagnostic comorbidity was examined relative to lifetime substance abuse, suicide attempt histories, and other clinical features. RESULTS: Thirty percent of subjects met DSM-IV criteria for a cluster B personality disorder (17% borderline, 6% antisocial, 5% histrionic, 8% narcissistic). Cluster B diagnoses were significantly linked with histories of childhood emotional abuse (p = .009), physical abuse (p = .014), and emotional neglect (p = .022), but not sexual abuse or physical neglect. Cluster B comorbidity was associated with significantly more lifetime suicide attempts and current depression. Lifetime suicide attempts were significantly associated with cluster B comorbidity (OR = 3.195, 95% CI = 1.124 to 9.088), controlling for current depression severity, lifetime substance abuse, and past sexual or emotional abuse. CONCLUSIONS: Cluster B personality disorders are prevalent comorbid conditions identifiable in a substantial number of individuals with bipolar disorder, making an independent contribution to increased lifetime suicide risk.     

Risk of suicide attempt and suicide death in patients treated for bipolar disorder

OBJECTIVES: To evaluate demographic and clinical predictors of suicide attempt and suicide death in a population-based sample of people treated for bipolar disorder (BD). METHODS: Computerized records were used to identify 32,360 individuals treated for BD at two large prepaid health plans. Suicide attempts were identified using computerized records of outpatient visit diagnoses and hospital discharge diagnoses. Suicide deaths were identified using state death certificate data. RESULTS: Overall event rates were 1.06 per 1,000 person-years for suicide death, 5.6 per 1,000 person-years for suicide attempt leading to hospitalization, and 13.9 per 1,000 person-years for suicide attempt not leading to hospitalization. Men had a significantly lower rate of suicide attempt [hazard ratio (HR) 0.68, 95% confidence interval (CI) 0.56-0.83] but a higher rate of suicide death (HR 2.70, 95% CI 1.69-4.31). Suicide attempts were significantly more frequent among younger patients, but suicide deaths did not vary significantly by age. Substance use comorbidity was significantly related to risk of suicide attempt (HR 2.53, 95% CI 2.07-3.09) but not to risk of suicide death (HR 1.02, 95% CI 0.54-1.93). Comorbid anxiety disorder was associated with significantly higher risk of both suicide attempt (HR 1.40, 95% CI 1.14-1.72) and suicide death (HR 1.81, 95% CI 1.09-2.99). CONCLUSIONS: Among people treated for BD, risk of suicide death is significantly related to male sex and comorbid anxiety disorder. The predictors of suicide death differ markedly from predictors of suicide attempt.     

Disentangling dysthymia from major depressive disorder in suicide attempters' suicidality, comorbidity and symptomatology

Dysthymia and major depressive disorder (MDD) are both risk diagnoses for suicidal behaviour. The aim of the present study was to identify clinical differences between these disorders, with a special reference to dysthymia. We studied suicidal behaviour, comorbidity and psychiatric symptoms of inpatient suicide attempters with dysthymia and MDD. We used DSM III-R diagnostics, the Suicide Assessment Scale (SUAS) and the Comprehensive Psychopathological Rating Scale (CPRS), part of which is the Montgomery and Asberg Depression Rating Scale (MADRS). Suicide mortality, number of repeated suicide attempts, method of suicide attempt and comorbidity of Axis I did not differ between the groups. Dysthymia patients, however, suffered more than MDD patients from DSM-III-R Axis II diagnoses (above all cluster B). There was no significant difference in Axis III comorbidity. Total SUAS, CPRS and MADRS scores did not differ significantly between the groups. When studying separate SUAS and CPRS items in a multivariate analysis, the CPRS items "aches and pains", "increased speech flow", increased "agitation" and "less tendency to worrying over trifles" as well as young age remained independently associated with dysthymia. Dysthymia patients, who later committed suicide, more often reported increased "aches and pains" than those who did not commit suicide. In this small sample of suicide attempters, we conclude that dysthymia suicide attempters, more often than MDD patients, have a comorbidity with personality disorders, which combined with a picture of aches and pains, could be factors explaining their suicidality.     

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.     

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.     

Sleep,suicide behaviors,and the protective role of sleep medicine

Objective/BackgroundSleep disturbance is associated with suicidal thoughts and behaviors. The relationship of specific sleep disorders to suicide attempts is less well established. Whether treating sleep disorders reduces suicide attempts remains controversial.MethodsSuicide attempts, treatment utilization, and psychiatric diagnoses were extracted from electronic medical records and a suicide attempt database from the U.S. Department of Veterans Affairs. The sample (N = 60,102) consisted of patients with any record of suicide attempt in FY13-14 and a 1:1 case-control of patients with no record of attempt, who were propensity score-matched based on age, gender, and prior year mental health treatment utilization. Associations among sleep disorders and suicide attempt were examined via logistic regression. Covariates included depression, anxiety, posttraumatic stress disorder (PTSD), bipolar, schizophrenia, substance use disorder (SUD), medical comorbidity, and obesity.ResultsInsomnia (OR = 5.62; 95% CI, 5.39–5.86), nightmares (odds ratio, OR = 2.49; 95% confidence interval, CI, 2.23–2.77), and sleep-related breathing disorders (OR = 1.37; 95% CI, 1.27–1.48) were positively associated with suicide attempt after accounting for age, gender, treatment utilization, and comorbid sleep disorders. Furthermore, when controlling for depression, anxiety, PTSD, bipolar, schizophrenia, substance use disorder (SUD), medical comorbidity, and obesity, insomnia (OR = 1.51, 95% CI, 1.43–1.59) remained positively associated with suicide attempt nightmares (OR = 0.96; 95% CI, 0.85–1.09) nor sleep-related breathing disorders (OR = 0.87, 95% CI = 0.79–0.94). Additionally, sleep medicine visits 180 days prior to index date were associated with decreased likelihood of suicide attempt for individuals with sleep disorders (OR = 0.86; 95% CI, 0.79–0.94).ConclusionInsomnia is associated with suicide attempt among veterans. Sleep medicine visits were associated with a reduced risk of suicide attempt in sleep disordered patients. The assessment and treatment of sleep disorders should be considered in context of strategies to augment suicide prevention efforts.     

What are the characteristics of adolescent hospitalized suicide attempters?

AIM: To study the specificity of hospitalized adolescent suicide attempters. METHOD: Among a national sample of students (n = 11,718, mean age = 16.6 years) studied in 1999, 9.2% (n = 1078) made at least one suicide attempt during their life (SA); 21.9% (n = 234) of them were hospitalized (HSA). We identified the risk factors (family, school, behavioral and psychological) of SA and HSA by comparing (by gender) a) suicide attempters to non-suicide attempters and b) hospitalized suicide attempters to non-hospitalized suicide attempters. RESULTS: Both for girls and boys, the risk factors for SA varied. However, certain risk factors, particularly depressive mood, low self-esteem and poor parent-child relationships, were not associated with hospitalization. Hospitalized suicide attempters had more personal and social problems. But there is an important difference according to gender: in boys, hospitalization is related to physical fighting (OR = 2.2) and offences (OR = 3.4), in girls to running away (OR = 1.7), consumption of illegal drugs other than cannabis (OR = 2.0), having a living standard outside average (OR = 2.0) and going to a private school (OR = 1.7). CONCLUSION: Suicide attempters with problem behavior are more at risk of being hospitalized than others. However, the difference between hospitalized and non-hospitalized subjects was smaller than expected.     

Suicidal ideation and attempts in bipolar I and II disorders

OBJECTIVE: Few studies have investigated the prevalence of and risk factors for suicidal ideation and attempts among representative samples of psychiatric patients with bipolar I and II disorders. METHOD: In the Jorvi Bipolar Study (JoBS), psychiatric inpatients and outpatients were screened for bipolar disorders with the Mood Disorder Questionnaire from January 1, 2002, to February 28, 2003. According to Structured Clinical Interviews for DSM-IV Axis I and II Disorders, 191 patients were diagnosed with bipolar disorders (bipolar I, N = 90; bipolar II, N = 101). Suicidal ideation was measured using the Scale for Suicidal Ideation. Prevalence of and risk factors for ideation and attempts were investigated. RESULTS: During the current episode, 39 (20%) of the patients had attempted suicide and 116 (61%) had suicidal ideation; all attempters also reported ideation. During their lifetime, 80% of patients (N = 152) had had suicidal behavior and 51% (N = 98) had attempted suicide. In nominal regression models, severity of depressive episode and hopelessness were independent risk factors for suicidal ideation, and hopelessness, comorbid personality disorder, and previous suicide attempt were independent risk factors for suicide attempts. There were no differences in prevalence of suicidal behavior between bipolar I and II disorder; the risk factors were overlapping but not identical. CONCLUSION: Over their lifetime, the vast majority (80%) of psychiatric patients with bipolar disorders have either suicidal ideation or ideation plus suicide attempts. Depression and hopelessness, comorbidity, and preceding suicidal behavior are key indicators of risk. The prevalence of suicidal behavior in bipolar I and II disorders is similar, but the risk factors for it may differ somewhat between the two.     

Is assessing for borderline personality disorder useful in the referral after a suicide attempt?

BACKGROUND: Management of suicide attempters accounts for 10% of the psychiatric activity in the emergency room. In this population, the prevalence of borderline personality disorder (BPD) is high (10 - 55%). These patients present poorer psychosocial outcome and more frequent suicide attempts repetitions. However, the utility of the assessment of BPD in the referral to a specific treatment plan has not been yet studied. OBJECTIVE: To examine the association between the assessment of a diagnosis of BPD after a suicide attempt and the referral from the emergency room to a specific treatment plan. HYPOTHESIS: Suicide attempters with BPD, according to clinicians diagnosis, differ in terms of severity from those without more risk factors of suicide attempt repetitions and poorer psychosocial functioning, and in psychiatric referral from the emergency room. METHOD: Our case-control study took place during 10 months in the Geneva general hospital. We continuously enrolled patients admitted to the emergency room for deliberate self poisoning and separated them into two groups (BPD and control) according to the clinician's diagnosis. Data from medical records were systemically and anonymously gathered. We compared BPD patients' socio-demographic and clinical characteristics, as well as psychiatric referral, with the control group. RESULTS: Of the 478 subjects admitted to the emergency room for deliberate self-poisoning, 99 (22.6%) were diagnosed BPD by clinicians. Compared to controls, they were more frequently female (OR=3.9) and living alone (OR=3.8) and more often resorted to psychiatric care (OR=2.9), notably to emergency care (OR=3.8). Past history of suicide attempt was also more frequent (OR=1.9) as was the use of neuroleptics in the attempt (OR=2.7). No difference was detected in terms of psychiatric referral after emergency room care. CONCLUSION: Even if borderline personality disorder in suicide attempters is associated with more severity criteria, it is not associated with a referral to a specific treatment plan.     

Rates and correlates of suicide attempts in first-admission psychotic patients

The relationship of attempted suicide to demographic characteristics, current and lifetime psychiatric diagnoses, clinical history, and current symptoms was assessed in a sample of 184 recently hospitalized psychotic patients. Forty-three patients (23%) had an attempt history, and 28 (15% of sample; 65% of attempters) made an attempt during the episode for which they were hospitalized. Demographic characteristics did not distinguish attempters from nonattempters. Variables significantly associated with having ever attempted suicide were current diagnosis of unipolar major depressive disorder but not bipolar; lifetime major depressive episode; a history characterized by a less acute onset, lower pre-admission psychosocial functioning, and episodes of physical violence; and a symptom picture characterized by greater depression, hopelessness, negative symptoms, hallucinations and less thought disorder. Those with a current attempt had significantly higher rates of lifetime history of major depression and less physical violence than those with past attempts only. The potential importance of the data for predicting future suicidal acts is discussed.     

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.     

Comorbid substance use reduces the health care contacts of suicide attempters with schizophrenia spectrum or mood disorders

Utilization of health care services has been found to differ between psychiatric disorders. However, the pattern of health care contacts among suicide attempters with mental disorders is not known. This study systematically investigated the pattern of health care contacts among suicide attempters with schizophrenia spectrum versus mood disorders with or without comorbid substance use disorders both before and after attempted suicide. All consecutive medically treated suicide attempters in Helsinki from January 15, 1997, to January 14, 1998, were identified (n = 1,198). Data were gathered on all their health care contacts within the 12 months before and after the index attempt. Whereas the clear majority of all suicide attempters with schizophrenia spectrum or mood disorders had a treatment contact during the 30 days following the attempt, half of those with pure substance use disorders were without any contact with health care. Comorbid substance use made treatment less likely after attempted suicide among both psychiatric disorder groups; those with schizophrenia spectrum and comorbid substance use disorders were seven times more often left without aftercare recommendation than those without substance use comorbidity. Comorbid substance use disorders among suicide attempters with schizophrenia spectrum disorders decrease the likelihood of active aftercare, despite high suicide risk.     

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.
