Temperament traits in male suicide attempters and violent offenders.

With the purpose of comparing temperament traits in subjects who have been violent towards others and with subjects who have shown self-directed violence, 34 male suicide attempters and 34 male violent offenders were matched for age and psychiatric diagnosis. Violent offenders with a history of suicide attempts were excluded. Temperament traits were assessed by means of the Karolinska Scales of Personality. The temperament profiles of suicide attempters and violent offenders were very similar, with high trait anxiety and very low socialization. Violent offenders displayed significantly higher social desirability (P < 0.001). Suicide attempters tended to have higher indirect aggression and monotony avoidance. Impulsiveness, verbal aggression, and inhibition of aggression were within the normal range in both groups. There were substantial temperamental similarities between suicide attempters and violent offenders. In order to disentangle the differential mechanisms behind aggression towards self and others, we probably need to consider historical as well as current situation factors in a systematic way.     

Relationship between self-disclosure and serious suicidal behavior

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

Alexithymia and suicidal behavior

A number of factors including hopelessness have been identified as amplifying suicide risk. Alexithymia has recently been investigated as a predictor of suicidal behavior. The prevalence of the personality trait alexithymia in suicide attempters as well as other predictors of suicidal behavior were investigated in this study. One hundred suicide attempters were compared to 60 healthy controls on the measures of hopelessness, alexithymia, depression and suicidal ideation. First-timers and repetitive suicide attempters, males and females, married and unmarried suicide attempters were compared to each other in the suicide attempter group. The correlations of hopelessness, depression and alexithymia with suicidal intent and suicide lethality were investigated. The suicide attempter group did not display significantly higher scores on the alexithymia measure, compared to healthy controls. Alexithymia neither seemed to be a prevalent personality trait in suicide attempters nor a sensitive predictor of suicidality. The subscales of Toronto Alexithymia Scale measuring difficulty in identification and expression of feelings also did not reveal a significant difference between the two groups. Suicide attempters were more depressive, more hopeless and displayed greater suicidal ideation than healthy controls. Severity of depression was a stronger predictor of suicidal intent than hopelessness in the suicide attempter group. The lethality of the suicide attempt did not correlate with any of the psychometric measures. These findings propose that difficulty in the identification and articulation of feelings does not comprise a risk factor for suicidal behavior.     

Characteristics of Recent Suicide Attempters with and without Borderline Personality Disorder

The present research compared recent suicide attempters with and without a diagnosis of Borderline Personality Disorder (BPD). One hundred and eighty recent suicide attempters, recruited in the Emergency Department, participated in extensive research interviews. Results showed that suicide attempters with BPD displayed greater severity of overall psychopathology, depression, hopelessness, suicidal ideation, past suicide attempts, and had poorer social problem solving skills than those without a BPD diagnosis. No differences were found between the groups regarding the intent to die or lethality associated with the index suicide attempt. These findings highlight the seriousness of BPD and the risk that individuals diagnosed with this disorder will attempt suicide.     

Thyroid hormones and personality traits in attempted suicide

The research on thyroid hormones and personality traits is quite sparse and mainly focused on male forensic psychiatric populations in which the relationship between thyroid hormones and psychopathy and aggression-related personality traits has been reported. The suicidal temperament hypothesis suggests that certain personality traits such as aggression, anxiety proneness, impulsivity, and low socialization may render an individual vulnerable to the risk of suicide. The aim of this study was to investigate personality traits assessed by the Karolinska Scales of Personality (KSP) in relation to hormones in the hypothalamic–pituitary–thyroid (HPT) axis in 100 euthyroid suicide attempters. Standard multiple regression analyses were performed with TSH, T3, T4, and the T3/T4 ratio, respectively, as the dependent variable and KSP factors (Anxiety Proneness, Aggressiveness, and Impulsivity) and subscales (Detachment, Social Desirability, and Socialization) as independent variables. In men, but not in women, the regression model of the T3/T4 ratio was significant and the results suggested that high scores on Aggressiveness and low ones on Detachment were associated with a low T3/T4 ratio. These results indicate that HPT function may be related to Aggressiveness and Detachment in male suicide attempters.     

Characteristics of recent suicide attempters with and without Borderline Personality Disorder.

The present research compared recent suicide attempters with and without a diagnosis of Borderline Personality Disorder (BPD). One hundred and eighty recent suicide attempters, recruited in the Emergency Department, participated in extensive research interviews. Results showed that suicide attempters with BPD displayed greater severity of overall psychopathology, depression, hopelessness, suicidal ideation, past suicide attempts, and had poorer social problem solving skills than those without a BPD diagnosis. No differences were found between the groups regarding the intent to die or lethality associated with the index suicide attempt. These findings highlight the seriousness of BPD and the risk that individuals diagnosed with this disorder will attempt suicide.     

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.     

Non-Suicidal Self-Injury and Interpersonal Violence in Suicide Attempters

The current study compared characteristics of suicidal behavior and interpersonal violence in suicide attempters with and without a history of non-suicidal self-injury (NSSI). A total of 100 suicide attempters were assessed with Karolinska Interpersonal Violence Scale (KIVS) and Karolinska Suicide History Interview concerning interpersonal violence and NSSI. There was a high degree of comorbid NSSI in suicide attempters (44%). Suicide attempters with NSSI-history reported more interpersonal violence as adults and more severe suicidal behavior compared to suicide attempters without NSSI. Comorbid NSSI was related to severity of suicidal behavior in a gender specific manner. Comorbid NSSI in suicide attempters may increase suicide and violence risk.     

The Role of Perfectionism and Depressive Cognitions in Understanding the Hopelessness Experienced by Adolescent Suicide Attempters

This study examined the relation of two cognitive variables, depressive cognitions and perfectionism, to the hopelessness experienced by adolescent suicide attempters. Adolescent suicide attempters (N = 68) were administered three measures assessing cognitive characteristics commonly associated with adolescent suicidal behavior: the Child and Adolescent Perfectionism Scale (CAPS), the Depressive Experiences Questionnaire for Adolescents (DEQ-A), and the Hopelessness Scale for Children (HSC). Socially prescribed perfectionism on the CAPS and self-criticism on the DEQ-A were both highly correlated with HSC. Regression analyses indicated that perfectionism was significantly related to hopelessness, but this relationship was attenuated after the effects of depressive cognitions on hopelessness were controlled. Self-criticism was the cognitive variable most strongly associated with hopelessness suggesting that it is a more important focus for cognitive interventions in adolescent suicide attempters than perfectionism.     

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.     

The correlates of planning in adolescent suicide attempts

Adolescent suicide attempts are often impulsive. It has been suggested that individuals who make nonimpulsive (premeditated) attempts have greater suicidal intent and are more hopeless than the impulsive attempters. Eighty-six adolescent suicide attempters were categorized according to the degree of premeditation of their attempt, as measured by two items of the Suicide Intent Scale. Sex, age, method of attempt, and the number of prior attempts were not useful discriminators between these groups. The nonimpulsive attempters were significantly more depressed and more hopeless than the impulsive attempters, as measured by several standardized scales. Measures of depression, hopelessness, and suicidal ideation were highly correlated in both groups. Anger turned inward and hopelessness were strongly correlated only in the premeditated group, suggesting that the nonimpulsive attempter's distress may bear a strong relationship to self anger.     

Relationships between attempted suicide, temperamental vulnerability, and violent criminality in a Swedish forensic psychiatric population.

The relationship between suicide attempts and different vulnerability factors was investigated in 61 male subjects during forensic psychiatric examination. Personality traits and psychopathy were determined by means of the Karolinska Scales of Personality (KSP) and the Psychopathy Checklist-Revised (PCL-R). Clinical diagnoses were determined by the use of Structured Clinical Interview for DSM-III-R (SCID). Platelet monoamine oxidase (MAO) activity was investigated in 58 subjects.Suicide attempters had extremely low socialization and high impulsive aggression. This was independent of a history of repeatedly criminal violence or not. They had higher PCL-R scores and lower levels of platelet MAO activity than non-attempters. No relationship was found between suicide attempts and repeated violent criminality. However, among the subjects with repeated criminal violence there was a highly significant difference between suicide attempters and non-attempters, indicating different personality profiles in violent offenders with and without suicidal behavior. Suicidal behavior was significantly associated with borderline personality disorder, but not with any other single DSM-III-R disorder. The results show a far more severe personality disturbance in suicide attempters than in other violent patients in this type of population. Suicidal behavior should therefore be evaluated and treated per se.     

Subjective psychological well-being (WHO-5) in assessment of the severity of suicide attempt

An objective way to measure the severity of suicide attempt is to use different psychometric scales. Aspects of suicide risk like suicidal intent, depression, hopelessness and well-being can be assessed and different practical scales are in use to facilitate the risk assessment procedure. The aims of current study were: 1) to analyse the association between the severity of suicide attempt measured by suicidal intent scale and characteristics of emotional status of suicide attempters measured by depression, hopelessness and well-being scales in different gender and age groups; 2) to test the applicability of well-being measured by the World Health Organisation well-being index (WHO-5) in suicide risk assessment. The data on suicide attempters (n=469) was obtained in Estonia (Tallinn) by the WHO Suicide Prevention-Multisite Intervention Study on Suicidal Behaviours (SUPRE-MISS) methodology. Different psychometric scales were used to measure suicidal intent (Pierce Suicidal Intent Scale) and emotional status (Beck Depression Inventory for depression, Beck Hopelessness Scale for hopelessness, WHO-5 for well-being). All psychometric scales correlated well with each other (P<0.05). Low level of well-being associated with high level of suicidal intent, depression and hopelessness. Suicidal intent correlated the most strongly with well-being. Analysis by gender and age groups revealed also significant correlations with two exceptions only: correlation between suicidal intent and hopelessness did not reach the significant level in males and in older adults (40+). The WHO-5 well-being scale, which is a short and emotionally positively loaded instrument measuring protective factors, can be used in settings without psychological/psychiatric expertise in preliminary suicide risk assessment.     

Assessing varying degrees of lethality in depressed adolescent suicide attempters.

OBJECTIVE: Understanding the lethality of suicide attempts and its relation to other psychological variables may improve clinical judgement with regard to suicide risk. METHOD: The lethality of suicidal behaviour was examined in 60 hospitalized adolescent in-patients who had recently attempted suicide. Subjects were divided into non-lethal, low-lethal and high-lethal groups based on the qualities of their suicidal acts. RESULTS: The groups did not differ in terms of hopelessness, depression, substance abuse or self-esteem. Moreover, they did not differ significantly in diagnoses of major depression, adjustment disorder, substance abuse and bipolar disorder. The group of high-lethal attempters was the only group with several individuals diagnosed with a major depressive episode and comorbid attention deficit disorder. The high-lethal group also reported the strongest desire to end their lives. CONCLUSION: Based on lethality of suicide attempts, adolescent suicide attempters can be differentiated in terms of the wish to die as well as some instances of diagnostic comorbidity. However, they may not be differentiated in terms of severity of depression or hopelessness, demographic variables and other aspects of suicidal behaviour.     

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.     

Suicidal ideation and attempts among psychiatric patients with major depressive disorder

BACKGROUND: Few studies have investigated risk factors for suicidal ideation and attempts, or possible variations in them, among representative samples of psychiatric patients with major depressive disorder. METHOD: As part of the Vantaa Depression Study in Vantaa, Finland, 269 patients with DSM-IV major depressive disorder (MDD), diagnosed by interview using semistructured World Health Organization Schedules for Clinical Assessment in Neuropsychiatry, version 2.0, and Structured Clinical Interview for DSM-III-R Personality Disorders, were thoroughly investigated. Information was gathered on patients' levels of depression, anxiety, hopelessness, perceived social support, social and occupational functioning, and alcohol use. Suicidal behavior was assessed by interviews, including the Scale for Suicidal Ideation, and by information from psychiatric records. Data were gathered from Feb. 1, 1997, to May 31, 1998. RESULTS: During the current MDD episode, 58% of all patients had experienced suicidal ideation; among the 15% of the total who had attempted suicide, almost all (95%) had also had suicidal ideation. In nominal regression models predicting suicidal ideation, hopelessness, alcohol dependence or abuse, low level of social and occupational functioning, and poor perceived social support were found to be significant (p < .05) independent risk factors. High severity of depression and current alcohol dependence or abuse in particular, but also younger age and low level of social and occupational functioning, predicted suicide attempt. CONCLUSION: Suicidal ideation is prevalent and appears to be a precondition for suicide attempts among psychiatric patients with MDD. The risk factors for suicidal ideation and attempts locate in several clinical and psychosocial domains. While these risk factors largely overlap, the overall level of psychopathology of suicide attempters is higher compared with that in patients with ideation, and substance use disorders and severity of depression may be of particular importance in predicting suicide attempts.     

Beyond the mental pain: A case-control study on the contribution of schizoid personality disorder symptoms to medically serious suicide attempts

BackgroundClinical and research findings have highlighted the role of interpersonal factors in suicidal behavior with high levels of intent and lethality. Schizoid personality disorder (SPD) is at the extreme end of interpersonal difficulties. Thus, we aimed to understand the contribution of SPD symptoms to suicide behavior and specifically to more lethal suicide attempts.MethodFour groups were investigated (N = 338): medically serious suicide attempters, medically non-serious suicide attempters, psychiatric and healthy controls. SPD symptoms, mental pain variants, and clinical characteristics were assessed.ResultsOverall, attempters were characterized by higher levels of most SPD symptoms. Solitary lifestyle and emotional detachment were higher among medically serious suicide attempters relative to less-serious attempters. Emotional detachment doubled the risk for high lethality, beyond mental pain variables.ConclusionsSPD symptoms of interpersonal difficulties and low levels of emotional expressions are important risk factors for more severe suicidal behavior. Implications for identification of at-risk groups for suicide are discussed.     

Personality Characteristics of Adolescent Suicide Attempters

Objective: The purpose of this study was to explore both the personality characteristics and the symptoms of personality disorder of adolescent suicide attempters, as well as the relationship between personality variables and hopelessness in this population. Method: Two sample populations were used in this study. First, 102 adolescent suicide attempters between 13 and 18 years of age completed the Millon Adolescent Personality Inventory (MAPI) and the Hopelessness Scale for Children (HSC). A second group of 35 adolescent suicide attempters were administered the HSC and the revised Diagnostic Interview for Borderlines (DIB). Results: No distinctive personality characteristics or symptoms of personality disorders were found. However, affective distress seemed to be the most prominent feature in the presentation of these adolescents. Additionally, high scores on the HSC were associated with elevated scores on the Personality Style scales of the MAPI and higher (more dysfunctional) scores on Affect Regulation on the DIB. Conclusions: The results suggest that clinicians should focus most on the personality characteristic of sensitivity and on affect regulation when assessing adolescent suicide attempters. In addition, hopelessness is important to systematically assess because it appears to be related to a variety of dysfunctional personality characteristics that may affect follow-up outcome.     

Depressive characteristics of adult psychiatric inpatients with a history of multiple versus one or no suicide attempts

Background: A growing body of research suggests that individuals with a history of multiple suicide attempts exhibit more severe psychopathology than individuals with only one or no previous suicide attempts. Given the strong link between diagnoses of major depression and suicide risk, our primary goal was to determine which specific depressive characteristics differentiate multiple attempters from patients with one or no previous attempts. Methods: Participants were 121 depressed adult psychiatric inpatients. Participants were administered diagnostic interviews to assess the course and characteristics of their depression history as well as measures of suicidal ideation, suicide attempts, depressive symptoms, hopelessness, and dysfunctional attitudes. Results: Patients with a history of multiple suicide attempts exhibited higher levels of suicidal ideation and depressive symptoms, but not hopelessness or dysfunctional attitudes, than the other two groups. In addition, multiple attempters reported an earlier age of major depression onset. Conclusions: The current results add to a growing body of research suggesting that multiple attempters may represent a distinct patient population. Depression and Anxiety, 2009.

Suicidal behaviour,social networks and psychiatric diagnosis

Summary The aim of this investigation was to examine the relationship between social network deficits and the occurrence of suicidal behaviour, and to describe the short-term interpersonal consequences of a suicidal attempt. Two questionnaires, concerned with the extent and self-perceived adequacy of social network, formed the basis of a structured interview. Fifty-two suicide attempters were interviewed within 48 hours of their attempt, and again six weeks later, and undertook a weekly self-rating task. A group of 52 non-suicidal individuals of comparable age, sex, social class, and marital and employment status underwent the same interview programme. The results indicate that the social networks of suicide attempters are impaired relative to non-suicidal individuals, and that improvement in the social network following an attempt is limited to attempters with no formal psychiatric disorder, and to measures of perceived adequacy and satisfaction. The findings add support to the importance of psychiatric assessment of the nature and the adequacy of the social network in relation to suicidal individuals.
