Abstract
The purpose of this study was to identify personality traits associated with suicide attempt in a clinical sample. Temperament and character inventory (TCI) profiles of 759 patients who met the inclusion criteria among 1000 randomly selected hospital records collected. Of these 759 patients, 103 had a history of at least 1 actual suicide attempt (suicidal group) whereas 656 had no such history (nonsuicidal group). The suicidal group showed higher scores of novelty seeking (mean ± SD: 36.1 ± 1.2 vs 33.3 ± 0.5; P = .026) and harm avoidance (57.1 ± 1.5 vs 53.0 ± 0.6; P = .01) but lower scores of self-directedness (27.5 ± 1.5 vs 34.4 ± 0.6; P < .001) than the nonsuicidal group. Higher novelty seeking (OR [95% CI]: 1.031 [1.008-1.054]; P = .007) and lower self-directedness: 0.955 [0.927-0.983]; P = .002 were also associated with suicide attempts in the analysis of 7 personality scales. These findings suggest that patients who attempt suicide differ from nonattempters in terms of personality traits, especially in novelty seeking (NS), harm avoidance (HA), and self-directedness (SD). It is noteworthy that this study contains data from actual visits to the emergency room to evaluate suicide attempts. Abbreviations: CO = cooperativeness, Ha = harm avoidance, NS = novelty seeking, PS = persistence, RD = reward dependence, SD = self-directedness, ST = self-transcendence, TCI = temperament and character inventory.

Abstract
OBJECTIVE To identify the psychiatric profile of patients hospitalized due to self-intoxication associated with suicide-related behavior (SRB). METHODS In this retrospective single-center study, records of consecutive patients treated for suicidal poisoning in our Clinical Toxicology unit between 1st January 2012 and 31st December 2016, who received at least one psychiatric exploration during their inpatient stay, were analyzed with regard to epidemiological data, ingested substances, psychiatric and somatic comorbidities, suicidal circumstances and follow-up therapy. RESULTS Out of 1289 hospitalized patients, 1090 patients with complete data were analyzed. Mean age was 40.5 ± 17.2 years, 66.7% were female. 32.0% of patients had previously engaged in SRB, in 76.3% intention was suicidal. 64.7% of patients had a pre-existing psychiatric disorder (PD). Patients with a pre-existing PD more often displayed prior SRB than those without PD (40.7% vs 15.3%; p < 0.001; Fisher's exact test), used long-term/on demand medication (70.2% vs 38.9%; p < 0.001), distanced themselves from the current suicide attempt (65.9% vs 50.8%; p < 0.001) and had no detectable trigger (38.7% vs 18.1%; p < 0.001). Partnership conflict was the most commonly named trigger, and it was documented more often in patients without than in those with PD (41.6% vs 25.6%). After psychiatric reevaluation, most patients were diagnosed with mood disorders (29.7%) and stress disorders (17.0%); 32.8% of patients had a combination of two or more PDs. CONCLUSION Hospitalization due to self-poisoning is associated with pre-existing PD, prior SRB and access to psychiatric medication. Detection of these risk factors could allow timely introduction of effective preventive measures tailored to particularly vulnerable subgroups and appropriate relief. However, lack of a detectable trigger in many cases may hamper the identification of those at risk.

Abstract
BACKGROUND To analyze the association between temperament (emotional and affective) and scrutinize the progression from suicide ideation to attempt, by using data from a large internet-based sample. METHODS It is a cross-sectional study, based on the Brazilian Internet Study on Temperament and Psychopathology (BRAINSTEP). Temperament was assessed by the Affective and Emotional Composite Temperament Scale (AFECTS), and life-long suicidal behavior was determined by the adapted Suicidal Behaviors Questionnaire (SBQ-17). Odds ratios were obtained through multivariate logistic regression and a multiple linear regression were used in the analysis. According to the "ideation-to-action framework", we performed analyzes using two different reference groups: no suicidal ideation and suicidal ideation. RESULTS The affective temperaments that showed the greatest association with suicide attempts were depressive, cyclothymic, and volatile. The temperaments that reflected higher associations for progression from ideation to suicide attempt were cyclothymic, depressive, and euphoric. Sensitivity was manifested as the emotional temperament with the strongest positive association with the severity of suicidal behavior, followed by desire and control. Stability was estimated as the emotional trait with the strongest negative association with the severity of suicidal behavior. LIMITATIONS It is not a population based sample. BRAINSTEP is a self-selected sample whose participants are mostly women, who are highly educated and young. CONCLUSIONS Our results suggest that temperament assessment using AFECT model may be relevant to assess the risk for the progression from ideation to suicide attempts. These results strengthen the "ideation-to-action" framework that risk factors to suicide ideators can differ from suicide attempters.

Abstract
BACKGROUND Early trauma is known to be a risk factor of suicide-related behavior. On the other hand, people who attempt suicide using a fatal method are reported to be more likely to complete suicide. In this study, we assumed that early trauma affects an individual's temperament and character and thereby increases the risk of a fatal method of suicide attempts. METHODS We analyzed 92 people with a history of previous suicide attempts. We compared the Temperament and Character Inventory-Revised scores between the groups with and without early trauma, and between the groups with and without a history of suicide attempt using fatal methods through an analysis of covariance with age, sex, and presence of a psychiatric history as covariates. A mediation analysis was conducted of the relationship between early trauma and fatal methods of suicide attempt with self-transcendence as a mediator. RESULTS Higher self-transcendence was reported in the fatal group (27.71 ± 13.78 vs. 20.97 ± 12.27, P = 0.010) and the early trauma group (28.05 ± 14.30 vs. 19.43 ± 10.73, P = 0.001), respectively. The mediation model showed that self-transcendence mediates the relationship between early trauma and fatal methods of suicide attempt. The 95% confidence intervals for the direct and indirect effect were (-0.559, 1.390) and (0.026, 0.947), respectively. CONCLUSION Self-transcendence may mediate the relationship between early trauma and fatal methods of suicide attempt. Self-transcendence may be associated with unhealthy defenses and suicidal behavior for self-punishment and may constitute a marker of higher suicide risk.

[PMID: 32984107 PMCID: PMC7491799 DOI: 10.4103/jfmpc.jfmpc_1200_19] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Revised: 02/26/2020] [Accepted: 04/08/2020] [Indexed: 11/28/2022] Open
Abstract
Aim: The present study strives to find an experimental response to these questions: “Is the relationship between neuroticism and suicidal thoughts a simple relationship? Or are there other psychopathological variables such as attachment styles that also affect it?” Subjects and Methods: In this cross-sectional study, 376 medical students were selected from the three major cities of Iran using multi-stage sampling method from July 2018 to September 2018 and were evaluated using the demographic information questionnaire, Beck Scale for Suicidal Ideation (BSSI), the Revised NEO Personality Inventory (NEO-FFI), and the Adult Attachment Questionnaire (AAQ). Results: The overall prevalence of having suicidal thoughts among Iranian medical students was 17%. Moreover, the prevalence of suicide among the female, widowed, separated, and divorced students was higher than others. There was also a significant correlation between suicidal thoughts, gender, relational status, neuroticism, avoidant insecure attachment style, secure attachment style, and anxious/ambivalent insecure attachment style. Additionally, the attachment styles have a moderating role in the relationship between neuroticism and suicidal thoughts. Conclusion: Based on the current study, it is concluded that despite the presence of neuroticism in medical students, the attachment styles can reduce the risk of suicide as moderator variables. Hence, attachment styles can be considered a potential treatment goal in the prevention of suicide.

Abstract
Major depressive disorder (MDD) is a complex psychiatric disease requiring multidisciplinary approaches to identify specific risk factors and establish more efficacious treatment strategies. Although the etiology and pathophysiology of MDD are not clear until these days, it is acknowledged that they are almost certainly multifactorial and comprehensive. Monoamine neurotransmitter system dysfunction and specific personality traits are independent risk factors for depression and suicide. These factors also demonstrate complex interactions that influence MDD pathogenesis and symptom expression. In this review, we assess these relationships with the aim of providing a reference for the development of precision medicine.

Abstract
BACKGROUND Among risk factors for suicidal behavior, there is growing interest in associations with stable affective temperament types, particularly based on assessment with the TEMPS-A self-rating scale. AIM As research on this topic has not been reviewed systematically, we synthesized relevant, reported research findings. METHODS Systematic searching identified peer-reviewed reports pertaining to associations of suicidal behavior or ideation with affective temperament types evaluated with TEMPS-A. We summarized available findings and applied quantitative meta-analytic methods to compare scale scores in suicidal versus nonsuicidal subjects. RESULTS In 21 of 23 TEMPS-A studies meeting inclusion criteria, anxious, cyclothymic, depressive, or irritable temperament scores were significantly higher with previous or recent suicide attempts or ideation in both psychiatric and general population samples compared to nonsuicidal controls, whereas hyperthymic temperament scores were lower in 9 of 11 reports. These findings were synthesized by random-effects meta-analyses of standardized mean differences in TEMPS-A temperament scores in suicidal versus nonsuicidal subjects. Associations ranked: depressive ≥ irritable > cyclothymic > anxious > hyperthymic (negative). CONCLUSIONS Affective temperaments, especially depressive and irritable, were strongly associated with suicidal risk, whereas hyperthymic temperament appeared to be protective.

Abstract
OBJECTIVE To examine the associations between personality traits and suicidal ideation (SI) and attempt (SA) in mood disorder patients and community controls. METHOD We recruited 365 bipolar, 296 major depressive disorder patients, and 315 community controls to assess their lifetime suicidality. Participants filled out self-reported personality questionnaires to collect data of personality traits, including novelty seeking (NS), harm avoidance (HA), extraversion (E), and neuroticism (N). We used logistic regression models adjusted for diagnoses to analyze combinational effects of personality traits on the risk of suicide. Additionally, radar charts display personality profiles for suicidal behaviours by groups. RESULTS All personality traits were associated with the risk of suicidality with various effect size, except for E that showed protective effect. High N or HA had prominent and independent risk effects on SI and SA. Combinations of high N and low E, or high HA and NS were the risk personality profiles for suicidality. Higher N scores further distinguished SA from SI in mood disorder patients. CONCLUSION Introvert personality traits showed independent risk effects on suicidality regardless of diagnosis status. Among high-risk individuals with suicidal thoughts, higher neuroticism tendency is further associated with increased risk of suicide attempt.

Abstract
BACKGROUND Assessment of affective temperaments with the extensively validated, 110-item TEMPS-A autoquestionnaire has been used to characterize patients with mood disorders, and its scores have been associated consistently with suicidal behavior. Much less has been reported about comparisons of characteristics of such assessments in psychotic and other psychiatric disorders. METHODS We analyzed results of TEMPS-A assessments in 1081 psychiatrically hospitalized patients in Rome and compared subscale scores (anxious [anx], cyclothymic [cyc], depressive [dep], irritable [irr], hyperthymic [hyp]) and a composite score (anx+cyc+dep+irr - hyp) among diagnoses and subjects with vs. without a suicide attempt. RESULTS TEMPS-A subscale scores differed significantly among diagnoses and were higher with major affective than psychotic or other disorders. Suicide attempts were 1.5-times more frequent among women than men and with affective versus nonaffective disorders, ranking: bipolar-II > major depression > bipolar-I > other disorders > psychotic disorders. TEMPS-A subscores were significantly higher among suicidal subjects (ranking: anx ≥ cyc ≥ dep > irr) except hyp (lower), but the composite score differed most (1.37-fold higher). Multivariable logistic regression modeling indicated that suicide attempt was significantly and independently associated with: TEMPS-A composite score > female sex > affective disorder > older age. CONCLUSIONS TEMPS-A scores, particularly a composite score (anx+cyc+dep+irr - hyp) may help effectively evaluate suicidal risk in association with nonaffective as well as affective disorders.

Abstract
OBJECTIVES Chronic and acute alcohol use are highly associated risk factors for suicides worldwide. Therefore, we examined suicide cases with and without alcohol use disorder (AUD) using data from the SNSF project "Suicide in Switzerland: A detailed national survey". Our investigations focus on correlations between acute and chronic alcohol use with reference to suicide and potential interactions with the methods of suicide. METHODS We used data from the SNSF project in which all cases of registered completed suicide in Switzerland reported to any of the seven Swiss institutes of legal and forensic medicine between 2000 and 2010 were collected. We extracted cases that were tested for blood alcohol to use in our analysis. We compared clinical characteristics, blood alcohol concentrations, and methods of suicide in cases with and without AUD. RESULTS Out of 6497 cases, 2946 subjects were tested for acute alcohol use and included in our analysis. Of the latter, 366 (12.4%) persons had a medical history of AUD. Subjects with AUD significantly had higher blood alcohol concentrations and were more often in medical treatment before suicide. Drug intoxication as method of suicide was more frequent in cases with AUD compared to NAUD. CONCLUSION Overall, we found a high incidence of acute alcohol use at the time of death in chronic alcohol misusers (AUD). The five methods of suicide most commonly used in Switzerland differed considerably between individuals with and without AUD. Blood alcohol concentrations varied across different methods of suicide independently from the medical history in both groups.

Abstract
Suicide is a major social and clinical problem in Asia. Although studies have suggested that personality traits are possible risk factors for suicide, no study has been conducted among Chinese to compare the temperament traits of suicidal and non-suicidal mood disorder patients with those of healthy controls. This study compared temperament traits of two patient groups, those with a mood disorder who have attempted suicide (n=204), and those with a mood disorder who have not attempted suicide (n=160), and compared the traits of these patients to those of healthy controls (n=178), assessed by Cloninger's Tridimensional Personality Questionnaire and the Brown-Goodwin Aggression Inventory. Patients with suicidal attempts had significantly higher novelty seeking and aggression scores than healthy controls and patients without suicidal attempts. Two groups of patients with mood disorder had significantly higher harm avoidance scores than the healthy controls. However, patients with suicidal attempts did not have higher harm avoidance scores than patients without suicidal attempts. This study confirms findings that harm avoidance and mood disorder are related, and extends them by suggesting that those with a mood disorder and suicide attempts have higher novelty seeking and lifetime aggression scores than those without suicidal attempt, either patients or healthy controls.

Suicidal Ideation vs. Suicide Attempts: Clinical and Psychosocial Profile Differences Among Depressed Patients: A Study on Personality Traits, Psychopathological Variables, and Sociodemographic Factors in 228 Patients. J Nerv Ment Dis 2017; 205:361-371.

Abstract
This study investigated whether personality traits, psychopathological characteristics, and sociodemographic factors in depressed patients differentiate patients with only suicidal thoughts from those who have attempted suicide. We investigated two groups of patients with an affective disorder: 198 patients with a suicide attempt within the last 3 months (sex ratio male to female, 1:1.3; mean age male to female, 44.8/44.7 years) and 30 patients without a suicide attempt but with suicidal thoughts (sex ratio male to female, 1:2; mean age male to female, 39.4/42.6 years) using a comprehensive measurement (Mini-International Neuropsychiatric Interview, Structured Clinical Interview for DSM-4 Axis II disorders, Hamilton Depression Scale, Beck Depression Inventory, State-Trait Anxiety Inventory, Hamilton Anxiety Scale, Brief Psychiatric Rating Scale, Clinical Global Impression Scale, Beck-Hopelessness Scale, Scale for Suicide Ideation, Impulsivity Rating Scale, Barratt Impulsivity Scale, Inventory for the Assessment of Aggression Factors, State-Trait Anger Expression Inventory, Ways of Coping Checklist). Several differences distinguished the two groups, namely, in personality traits such as anxiety or coping strategies and sociodemographics (e.g., education level). Personality traits, psychopathological characteristics, and sociodemographic factors are useful tools for assessing suicidal risk. Our findings encourage us to suggest that clinicians pay particular attention to sociodemographic variables such as separation/divorce and a lower education level when conducting risk assessments on suicidal patients.

Differential associations of affective temperaments and diagnosis of major affective disorders with suicidal behavior. J Affect Disord 2017; 210:19-21. [PMID: 27992854 DOI: 10.1016/j.jad.2016.12.003] [Citation(s) in RCA: 100] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2016] [Accepted: 12/12/2016] [Indexed: 12/25/2022]
Abstract
BACKGROUND Affective temperaments are associated with suicidal risk, but their predictive value relative to diagnosis of major affective disorder is uncertain. METHODS We compared diagnoses, affective-temperament ratings (TEMPS-A), and other potential risk factors in 956 psychiatric inpatients, using bivariate analyses and multivariable logistic regression modeling for associations with suicidal status. RESULTS Lifetime suicide-attempt rates were high (43.9% overall), ranking by diagnosis: bipolar-II (58.4%), major depressive (50.0%), bipolar-I (44.6%), other (38.0%), and psychotic (33.9%) disorders. TEMPS-A scores for depressive (dep), cyclothymic (cyc), irritable (irr), and anxious (anx) temperaments and their sum were strongly associated with suicidal risk; hyperthymic (hyp) temperament scores were inversely associated; and a composite measure (dep+cyc+irr+anx - hyp), even more strongly associated. The composite score was highly, independently associated with suicidal behavior (p<0.0001), as was female sex (p=0.0002), but older age and diagnosis of major affective disorder, much less (both p=0.02). CONCLUSIONS Measures of affective temperament-types were independently and more strongly associated with lifetime suicide attempt than was diagnosis of a major affective disorder. However, in this hospitalized cohort, suicide rates were high across diagnoses, possibly limiting the predictive value of diagnosis.

Abstract
Affective temperaments are the subclinical manifestations or phenotypes of mood states and hypothetically represent one healthy end of the mood disorder spectrum. However, there is a scarcity of studies investigating the neurobiological basis of affective temperaments. One fundamental aspect of temperament is the behavioral reactivity to environmental stimuli, which can be effectively evaluated by use of cognitive event-related potentials (ERPs) reflecting the diversity of information processing. The aim of the present study is to explore the associations between P300 and the affective temperamental traits in healthy individuals. We recorded the P300 ERP waves using an auditory oddball paradigm in 50 medical student volunteers (23 females, 27 males). Participants' affective temperaments were evaluated using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-auto questionnaire version (TEMPS-A). In bivariate analyses, depressive temperament score was significantly correlated with P300 latency ( rs = 0.37, P < .01). In a multiple linear regression analysis, P300 latency showed a significant positive correlation with scores of depressive temperament (β = 0.40, P < .01) and a significant negative one with scores of cyclothymic temperament (β = -0.29, P = .03). Affective temperament scores were not associated with P300 amplitude and reaction times. These results indicate that affective temperaments are related to information processing in the brain. Depressive temperament may be characterized by decreased physiological arousal and slower information processing, while the opposite was observed for cyclothymic temperament.

Abstract
Personality features have been correlated with suicidal behaviors in recent decades. Given its neurobiological background, Cloninger's model of personality, the Temperament and Character Inventory (TCI), may help to identify the maternal and paternal personality dimensions associated with adolescent suicide attempts. The present study is the first that specifically compares the temperament and character profiles of both mothers and fathers of the adolescent suicide attempters with a control group, by considering the influence of demographic and clinical factors. The study group comprised 117 parents of 71 adolescent suicide attempters and 119 parents of 71 age- and gender-matched adolescents without a suicide attempt included as a control group. The TCI and Brief Symptom Inventory (BSI) were applied to the parents in both groups. Logistic regression analysis, which was performed to adjust confounding factors, demonstrated significantly higher scores for harm avoidance among the mothers and lower scores of self-directedness among the fathers of the adolescent suicide attempters. New psychotherapeutic modalities considering the high-risk parental personality traits would be beneficial to support parent-adolescent relationships and may have a preventative effect on adolescent suicide.

Abstract
Suicidal behaviors are serious public health problems. The prominent association of mood disorders with suicide, along with the renaissance of the spectrum concept of psychiatric disorders in the recent decades, prioritizes the investigation of temperament variants in suicidal individuals. This study aimed to explore the relationship between affective temperaments and nonviolent suicide attempts. We administered Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Auto questionnaire (TEMPS-A) to 141 (27 males and 114 females) consecutive self-poisoning non-lethal suicide attempters at a Medical Toxicology Center and a sex and age matched group of healthy individuals (28 males, 112 females). Female suicide attempters scored significantly higher in depressive, cyclothymic, irritable, and anxious temperaments compared with female controls, whereas male cases' scores were significantly higher in depressive and anxious subscales compared with control males. Except for hyperthymic temperament which did not reveal any significant effects, depressive (OR: 11.5), cyclothymic (OR: 3.8), irritable (OR: 2.3), and anxious (OR: 8.8) temperaments were predictors for nonviolent suicide attempts. Therefore, this study replicated the evidence for the strong association of depressive temperament with suicide attempts. The hyperthymic temperament appeared to have neither protective nor predisposing influence. Further studies are needed to identify the role of this independent temperament.

Abstract
BACKGROUND On the way toward an agreed dimensional taxonomy for personality disorders (PD), several pivotal questions remain unresolved. We need to know which dimensions produce problems and in what domains of life; whether impairment can be found at one or both extremes of each dimension; and whether, as is increasingly advocated, some dimensions measure personality functioning whereas others reflect style. METHOD To gain this understanding, we administered the Temperament and Character Inventory to a sample of 862 consecutively attended outpatients, mainly with PDs (61.2%). Using regression analysis, we examined the ability of personality to predict 39 variables from the Life Outcome Questionnaire concerning career, relationships, and mental health. RESULTS Persistence stood out as the most important dimension regarding career success, with 24.2% of explained variance on average. Self-directedness was the best predictor of social functioning (21.1%), and harm avoidance regarding clinical problems (34.2%). Interpersonal dimensions such as reward dependence and cooperativeness were mostly inconsequential. In general, dimensions were detrimental only in one of their poles. CONCLUSIONS Although personality explains 9.4% of life problems overall, dimensions believed to measure functioning (character) were not better predictors than those measuring style (temperament). The notion that PD diagnoses can be built upon the concept of "personality functioning" is unsupported.
