One-year follow-up study of first suicide attempts in first episode psychosis: Personality traits and temporal pattern

ObjectivesThe highest suicide rates occur after psychiatric hospitalization or soon after discharge. In addition to other factors, personality traits have been suggested as predictors of suicide attempts (SA) after first episode psychosis (FEP). In this study we examined their temporal pattern and the influence of personality traits on first suicide attempts (fSA) during one year after FEP.MethodOne-year follow-up of 65 FEP patients. Bivariate and multivariable analyses were performed to explore the relationship between personality traits and fSA. This analysis was also adjusted for a set of sociodemographic, clinical and psychopathological variables.ResultsfSAs in the six months following FEP were predicted by higher scores in passive-dependent personality traits (OR = 2.42, 95% CI = 1.15–5.09) and severity of symptoms at onset (OR = 2.00, 95% CI = 1.07–3.76). Severity of symptoms at onset (OR = 2.71, CI = 1.15–6.39) was the most significant predictor of fSA from six to twelve months after FEP. Seventy percent of fSA occurred during the first six months after FEP, decreasing considerably afterwards.ConclusionsOur study suggests that personality traits play a role in fSA after FEP. Specifically, passive-dependent personality traits emerged as a predictor of fSA in the six months following FEP. Severity of symptoms at onset predicted early and late first suicide attempts. We also found that risk of fSA is highest during the six months following FEP. These results can contribute to the implementation of prevention program.     

Predictors and correlates of suicide attempts over 5 years in 1,237 alcohol-dependent men and women

OBJECTIVE: In previous studies, factors related to a history of suicide attempts in persons with alcohol dependence have included sociodemographic variables, a more severe course of alcoholism, additional substance use disorders, and psychiatric comorbidity. This 5-year prospective study evaluated attributes associated with suicide attempts in a group of treatment-seeking persons with alcohol dependence. Psychiatric comorbidity was examined in terms of a distinction between substance-induced and independent psychiatric disorders. METHOD: Semistructured interviews were conducted with 1,237 alcohol-dependent subjects from the Collaborative Study on the Genetics of Alcoholism both at an initial evaluation and at a 5-year follow-up. Clinically relevant information was gathered at baseline, and suicidal behavior, aspects of alcohol dependence, and drug use were evaluated at the follow-up interview. RESULTS: Alcohol-dependent subjects (N=56) with suicide attempts during the follow-up period were more likely than subjects with no suicide attempts (N=1,181) to have made prior attempts. Other factors related to future suicide attempts in univariate analyses included younger age, being separated or divorced, other drug dependence, substance-induced psychiatric disorders, and indicators of a more severe course of alcoholism. Gender did not predict future attempts. CONCLUSIONS: A 5-year prospective evaluation of attributes associated with suicide attempts among alcohol-dependent persons identified factors that contributed to a small but significant proportion of the variance for future suicidal behavior.     

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

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

Anxiety disorders and risk for suicide attempts: findings from the Baltimore Epidemiologic Catchment area follow-up study

Our objective was to determine whether the presence of an anxiety disorder was a risk factor for future suicide attempts. Data were drawn from the 13-year follow-up Baltimore Epidemiological Catchment Area survey (n=1,920). Multiple logistic regression analysis was used to determine the association between baseline anxiety disorders (social phobia, simple phobia, obsessive-compulsive disorder, panic attacks, or agoraphobia) and subsequent onset suicide attempts. The presence of one or more anxiety disorders at baseline was significantly associated with subsequent onset suicide attempts (adjusted odds ratio 2.20, 95% confidence interval 1.04-4.64) after controlling for sociodemographic variables and all baseline mental disorders assessed in the survey. These findings suggest that anxiety disorders are independent risk factors for suicide attempts, and underscore the importance of anxiety disorders as a serious public health problem.     

A subscale for negative symptoms from the Comprehensive Psychopathological Rating Scale (CPRS): a comparison with the Schedule for Assessment of Negative Symptoms (SANS)

The Comprehensive Psychopathological Rating Scale (CPRS) was used to determine symptomatology in 145 schizophrenic patients. In 40 of these patients the Schedule for Assessment of Negative Symptoms (SANS) was also applied in order to determine which items in the CPRS represent negative schizophrenic symptoms. Of the patients, 115 were drug-free and 30 were treated with major transquilizers at the time of the rating. A principal component analysis with oblique solution and Varimax rotation grouped the items from CPRS into ten factors. These factors were subsequently correlated to the total scores of the SANS. When a factor showed a positive correlation with the SANS, the individual items within the factor were examined for correlation to both the subscales and the total SANS scores. Of the 33 items, 5 used in the CPRS showed a positive correlation with the SANS and were therefore considered to represent negative symptomatology in schizophrenia. These items were withdrawal, reduced speech, lack of appropriate emotions, slowness of movements and indecision. The items were grouped as a negative symptom subscale in the CPRS.     

Prospective predictors of suicide and suicide attempts in 1,556 patients with bipolar disorders followed for up to 2 years

Objectives:  Bipolar disorders are associated with high rates of suicide attempts (SAs) and completions. Several factors have been reported to be associated with suicide in persons with bipolar disorder, but most studies to date have been retrospective and have not utilized multivariate statistics to account for the redundant prediction among variables submitted for analysis.
Methods:  This study examined the association between baseline clinical and demographic variables and subsequent SAs and completions through 2 years of follow-up of participants in the Systematic Treatment Enhancement Program for Bipolar Disorder using a pattern-mixture model.
Results:  Of the sample with complete data (n = 1,556), 57 patients (3.66%) experienced an SA or completion (CS). Several variables predicted suicidality (SA + CS) in this data set when considered alone, but after controlling for redundant prediction from other baseline characteristics, only history of suicide [odds ratio (OR) = 4.52, p < 0.0001] and percent days depressed in the past year (OR = 1.16, p = 0.036) were significantly associated with SAs and completions. A secondary analysis included a greater number of variables but a smaller sample size (n = 1,014). In the secondary analyses, only prior SAs predicted prospective suicidality (OR = 3.87, p = 0.0029).
Conclusions:  These results indicate that patients with bipolar disorder who present with a history of SAs are over four times as likely to have a subsequent SA or completion. Further studies are needed to evaluate and prevent future attempts in this high-risk cohort.     

Concurrent adversities and suicide attempts among Sami and non-Sami adolescents: the Norwegian Arctic Adolescent Study (NAAHS)

Background: Little is known about connections between adolescent suicide attempts (SA) and concurrent adversities.

Aims: In a cross-sectional study, the authors wanted to investigate prevalences, additive effects of adversities, family and peer relations, gender, divorce and poverty, and ethnic differences between Sami and non-Sami youth.

Methods: In an adolescent community population encompassing 4881 adolescents of 15–16 years of age, youth with and without self-reports of attempted suicide the last year were compared on 12 concurrent adversities, on scales assessing family and peer functioning, and on sociodemographic variables.

Results: The prevalence of attempted suicide the last year was 5.3%, and more girls (8.8%) than boys (1.8%). All 12 concurrent adversities were strongly related to SA. The suicide attempters reported two and a half times as many adversities as non-attempters. A strong multiple additive relationship was found. Multivariately, among boys, the strongest risk factors were suicide among friends (OR?=?9.4), and suicide in the family or in the neighbourhood (OR?=?4.8). Among girls, sexual abuse (OR?=?5.2) and parent mental problems (OR?=?4.6) were strongest related to SA. Suicide attempters reported more divorce and poverty, more conflicts with parents, and less family support and involvement. Totally, Sami youth reported more SA and more concurrent adversities than non-Sami peers.

Conclusion: Adolescent suicide attempters are heavily burdened with concurrent adversities. Clinicians should be aware of gender differences in risk factors, and should ask about abuse and suicide or attempts among relatives and peers. A family perspective in clinical work is needed.     

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.     

Self-harm in children 12 years and younger: characteristics and outcomes based on the Multicentre Study of Self-harm in England

Background

Very little is known about self-harm in children. We describe the characteristics and outcomes of children under 13 years who presented following self-harm to five hospitals in England.

Methods

We included children under 13 years who presented after self-harm to hospitals in the Multicentre Study of Self-harm in England. Information on patients’ characteristics and method of self-harm was available through monitoring of self-harm in the hospitals. Area level of socioeconomic deprivation was based on the English Index of Multiple Deprivation (IMD).

Results

387 children aged 5–12 years presented to the study hospitals in 2000–2016, 39% of whom were 5–11 years. Boys outnumbered girls 2:1 at 5–10 years. The numbers of boys and girls were similar at age 11, while at 12 years there were 3.8 girls to every boy. The proportion of study children living in neighbourhoods ranked most deprived (43.4%) was twice the national average. 61.5% of children self-poisoned, 50.6% of them by ingesting analgesics. Of children who self-injured, 45.0% self-cut/stabbed, while 28.9% used hanging/asphyxiation. 32% of the children had a repeat hospital presentation for self-harm, 13.5% re-presented within a year.

Conclusions

Gender patterns of self-harm until age 11 years are different to those of adolescents, with a male preponderance, especially in 5–10 years, and hanging/suffocation being more common. The frequent use of self-poisoning in this age group highlights the need for public health messages to encourage safer household storage of medicines. Self-harm in children is strongly associated with socioeconomic deprivation; understanding the mechanisms involved could be important in effective prevention.

     

Personality and attempted suicide in depressed adults 50 years of age and older: a facet level analysis

We examined the contribution of personality traits to attempted suicide, the number of suicidal attempts, and suicidal ideation in a sample of depressed inpatients. Personality was assessed via the Revised NEO Personality Inventory (NEO-PI-R). Bivariate analyses showed that suicide attempters were more self-conscious, self-effacing, impulsive, and vulnerable to stress, and less warm, gregarious, and inclined to experience positive emotions. Multivariate regression analyses controlling for age, gender, severity of depression, and psychiatric comorbidity showed that patients with a lifetime history of attempted suicide were less inclined to experience positive emotions and be more self-effacing. Patients with more severe suicidal ideation were less warm and more self-effacing. Results indicated that specific personality traits confer risk for suicidal behaviors in middle age and older adults. Interventions tailored to specific personality profiles in this high-risk group should be developed, and their efficacy examined.     

Lack of association between endothelial nitric oxide synthase (NOS3) gene polymorphisms and suicide attempts

Objective  

The aim of this study is to investigate the association between two polymorphisms of endothelial nitric oxide synthase (NOS3) and suicide attempts.     

Suicide attempts before joining the military increase risk for suicide attempts and severity of suicidal ideation among military personnel and veterans

Objective

Past self-injurious thoughts and behaviors (SITB) are robust predictors of future suicide risk, but no studies have explored the prevalence of SITB occurring prior to military service among military personnel and veterans, or the association of premilitary SITB with suicidal ideation and suicide attempts during or after military service. The current study explores these issues in two separate samples.

Method

Self-report data were collected from 374 college student veterans via anonymous only survey (Study 1) and from 151 military personnel receiving outpatient mental health treatment (Study 2).

Results

Across both studies, premilitary suicide attempts were among the most prominent predictor of subsequent suicide attempts that occurred after joining the military, even when controlling for demographics and more recent emotional distress. Among military personnel who made a suicide attempt during or after military service, approximately 50% across both samples experienced suicidal ideation and up to 25% made a suicide attempt prior to joining the military. Military personnel and veterans who made suicide attempts prior to joining the military were over six times more likely to make a later suicide attempt after joining the military. In Study 2, significantly more severe current suicidal ideation was reported by participants with histories of premilitary suicide risk, even when controlling for SITB occurring while in the military.

Conclusions

Military personnel and veterans who experienced SITB, especially suicide attempts, prior to joining the military are more likely to attempt suicide while in the military and/or as a veteran, and experience more severe suicidal crises.     

A rating scale for psychotic symptoms (RSPS): part II: subscale 2: distraction symptoms (catatonia and passivity experiences subscale 3: delusions and semi-structured interview (SSCI-RSPS).

In the second paper on the Rating Scale for Psychotic Symptoms (RSPS), distraction symptoms (Subscale 2) and delusions (Subscale 3) are described. Subscale 2 includes distraction symptoms, which arise from one of two mechanisms: the symptom may arise either by loss of attentional focus (LAF) due to a competing channel of information, or by the intrusion of the competing channel into the focus of attention [attentional intrusions (AI)]. The symptom classes resulting from loss of attentional focus (LAF) include motor catatonia, negativism, and thought blocking; the attentional intrusions (AI) symptoms rated include three types of passivity experiences (Schneiderian symptoms): (1) thought insertion, (2) movements or action controlled, and (3) speech controlled by an external force. Subscale 3, consisting of delusions, is organized on the basis of content identification. Nineteen types of delusions are rated. Each item of delusional content is rated along three axes (active elaboration, persistence and active extinction) and complexity, and optionally if primary or mixed (i.e. primary with secondary elaborations). The last section of the paper includes the semi-structured interview (SCI-RSPS) for each of the items, as well as guidelines for practical application of the interview.     

Prevalence of and risk factors for lifetime suicide attempts in the National Comorbidity Survey.

BACKGROUND: General population survey data are presented on the lifetime prevalence of suicide attempts as well as transition probabilities to onset of ideation, plans among ideators, and attempts among ideators either with or without a plan. Risk factors for these transitions are also studied. METHODS: Data are from part II of the National Comorbidity Survey, a nationally representative survey carried out from 1990 to 1992 in a sample of 5877 respondents aged 15 to 54 years to study prevalences and correlates of DSM-III-R disorders. Transitions are estimated using life-table analysis. Risk factors are examined using survival analysis. RESULTS: Of the respondents, 13.5% reported lifetime ideation, 3.9% a plan, and 4.6% an attempt. Cumulative probabilities were 34% for the transition from ideation to a plan, 72% from a plan to an attempt, and 26% from ideation to an unplanned attempt. About 90% of unplanned and 60% of planned first attempts occurred within 1 year of the onset of ideation. All significant risk factors (female, previously married, age less than 25 years, in a recent cohort, poorly educated, and having 1 or more of the DSM-III-R disorders assessed in the survey) were more strongly related to ideation than to progression from ideation to a plan or an attempt. CONCLUSIONS: Prevention efforts should focus on planned attempts because of the rapid onset and unpredictability of unplanned attempts. More research is needed on the determinants of unplanned attempts.     

Lack of association between polymorphic variations in the alpha 3 subunit GABA receptor gene (GABRA3) and suicide attempts

This is the first case-control study exploring the association between suicide attempts and the polymorphic variations of the alpha 3 subunit gamma-aminobutyric acid (GABA) receptor gene (GABRA3) located in chromosome X. In a Spanish general hospital, 184 suicide attempters (127 women and 57 men) and 275 control blood donors (109 women and 166 men) were recruited. The four frequent variants (A1, A2, A3 and A4) of GABRA3 were studied. There were no significant differences in the total or by-gender frequencies of the four alleles. In females, there were no significant differences in the genotypes. This study can rule out even small size effects in the total sample and suggests a lack of association between GABRA3 polymorphism and suicide attempt, in the Spanish population.     

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

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

Head-injured subjects aged over 50 years: correlations between variables of trauma and neuropsychologial follow-up

Summary Neuropsychological follow-up was studied in 70 consecutive head-injured subjects aged over 50 years. Diffuse deterioration (28%), moderate deterioration (25%) and dementia (21%) were the most frequent sequelae. Analysis of correlations between neuropsychological sequelae and trauma variables showed that: (1) mild trauma did not necessarily imply good prognosis and could be followed by very severe consequences; (2) duration of post-traumatic amnesia was correlated with coma duration but not with neuropsychological out come; (3) on the whole, no prognostic predictor of the outcome was found.
