Personality traits are important candidate predictors of suicidal behavior. Several studies have reported an association between personality/temperament traits and suicidal behavior, suggesting personality traits as intermediary phenotypes related to suicidal behavior. Thus, it is possible that suicide attempts can be accounted for by increased familial rates of risk personality traits. The aim of this work was to evaluate personality traits in affective disorder patients with attempted suicide and to compare them with the personality trait scores of their parents. In addition, ITC scores in the two groups were compared with a healthy control sample. The patients evaluated met the DSM-IV criteria for major depression disorder or dysthymia and had a documented history of suicide attempts. Psychiatric diagnoses of patients and parents were done according to the SCID-I and the personality was assessed using the Temperament and Character Inventory. We analyzed 49 suicide attempt subjects and their parents (n=95) and 89 control subjects. We observed that temperament and character dimensions were similar between patients and their parents (P>0.05). In particular, we observed that high HA and low P, SD, and CO were shared among families. Our study is the first to report that the personality traits of affective disorder patients with a history of attempted suicide are shared between patients and their parents.

Objective: Research in adults has identified an association between bipolar disorder and suicidal behavior. This relationship, however, has been insufficiently investigated in adolescents to date. Methods: 1,117 adolescents from 13 German schools (mean age = 14.83, SD = .63; 52.7% females) completed an extended German version of the Center for Epidemiological Studies Depression Scale (CES-D), which assesses depressive and manic symptoms during the last week, as well as the Self-Harm Behavior Questionnaire (SHBQ) for the assessment of lifetime suicidal behavior. Results: In the present sample 39.4% of the girls and 23.1% of the boys reported lifetime suicidal thoughts and 7.1% of the girls as well as 3.9% of the boys a lifetime history of suicide attempts. 18.7% of the adolescent sample revealed elevated symptoms of depression and 9% elevated levels of mania symptoms. Elevated sum scores of depression and mania were associated with a higher number of suicidal ideations and suicide attempts. A block-wise regression analysis revealed that sum scores of depression and mania predicted suicidal ideations best. Concerning suicide attempts, the best predictors were age as well as depression and mania sum scores. Conclusions: Suicidal behavior was reported more often when adolescents demonstrate symptoms of mania as well as symptoms of depression than when they demonstrate only depressive symptoms. The presence of bipolar symptoms in adolescents should alert clinicians to the heightened possibility of suicidal behavior.

Abstract Study Objectives Insomnia is a risk factor for suicidal behavior including attempts and death by suicide. We investigated whether insomnia symptom severity was associated with suicidality and death by suicide in patients with psychiatric disorders. Methods The sample included 180 deceased patients with psychiatric disorders seen at Weber Human Services between 2008 and 2018 who completed the Outpatient Questionnaire-45.2 (OQ) prior to death. Insomnia symptom severity was assessed using item 41 from the OQ. Manner of death was determined by death records and autopsy reports. History of suicidality was determined through electronic medical records. Cases were grouped into 4 lifetime categories: non-suicidal (n=30), suicidal ideation (n=36), suicide attempt (n=95), and death by suicide (n=19). Demographic, medical, and psychiatric features of each group were compared using linear regression. Logistic regression was used to determine whether insomnia symptom severity was associated with lifetime suicidality severity grouping, adjusting for psychiatric disorders commonly linked to suicidality. Results Lifetime suicidality was associated with sleep problems, fatigue, headaches, and psychiatric disorders (i.e., depressive, personality, and trauma-related disorders). Referenced to the non-suicidal group, greater insomnia symptom severity was significantly associated with suicide attempts and death by suicide, with odds ratios (OR) of OR=2.67, p=0.011, and OR=5.53, p=0.002, respectively, even after adjusting important psychiatric diagnoses. Conclusions Results suggest that insomnia symptom severity endorsed during a clinical visit is associated with heightened suicidality, especially suicidal behavior. The presence of insomnia symptoms in patients with psychiatric disorders may indicate risk for suicide and is a target for suicide prevention.

OBJECTIVE: The objective of this study was to test the hypothesis that the polarity of the first mood episode may be a marker for suicidal behavior, particularly the violent subtype. METHOD: One hundred and sixty-eight patients diagnosed with bipolar disorder (DSM-IV) were grouped according to type of first episode: depression or manic/hypomanic. Groups were compared for demographic and clinical variables. We performed logistic regression in order to test the association between first episode polarity and suicidal behavior. RESULTS: We found that depressed patients have a lifetime history of more suicide attempts. However, univariate analysis of number of suicide attempts showed that the best model fits the bipolar II subtype (mean square = 15.022; p = 0.010) and lifetime history of psychotic episodes (mean square = 17.359; p = 0.021). Subgrouping the suicide attempts by subtype (violent or non-violent) revealed that manic/hypomanic patients had a greater tendency toward attempting violent suicide (21.2 vs. 14.7%, X² = 7.028, p = 0.03). Multiple logistic regression analysis confirmed this result. CONCLUSION: Depressed patients had more suicide attempts over time, which could be explained by the higher prevalence of bipolar II subtype in this group, whereas manic/hypomanic patients had a lifelong history of more frequent violent suicide attempts, not explained by any of the variables studied. Our results support the evidence that non-violent suicide attempters and violent suicide attempters tend to belong to different phenotypic groups.

Several studies have been conducted to establish a profile of the suicidal/parasuicidal patient. Also several factors have been identified as possibly influencing the suicidal rates, including the religious practices.Objectives:Characterize the profile of suicidal behavior in a sample of patients followed in a general psychiatric consultation.Methods:It was done an analytical observational study of a random sample of 100 patients followed in a general psychiatric consultation. A survey was conducted with the collection of socio-economic, religious aspects and clinical data, and it was consulted the patient"s clinical process. Data analysis was done in Excel 2003.Results:The sample was consisted mostly by women (74%), being the most representative age group between 40 and 50 years (27%), mostly married (61%), 24% had 2 children and 65% lived in the rural area. The clinical diagnosis (ICD-9) was in 46% of cases, neurotic depression. 52% consider themselves religious not practitioners, being 90% catholics. History of suicide attempts/parasuicide occurred in 32% of patients, in the form of drug intoxication (31%) or with another method (11%). Most of the individuals said to have already thought about suicide at least once in their lifetime (74%). Only 8% had current suicidal ideation. Family history of suicide occurred in 27%, particularly in first degree family members, mainly by drowning (7%) and hanging (7%).Conclusions:Our results suggest that exists a high prevalence of suicidal behavior in this patients. For that reason, it should be done a systematic screening for suicidal ideation in this risk population.

Abstract Background The serotonin 1A (5-HT1A) receptor has been implicated in depression and suicidal behavior. Lower resting cortisol levels are associated with higher 5-HT1A receptor binding, and both differentiate suicide attempters with depression. However, it is not clear whether 5-HT1A receptor binding and cortisol responses to stress are related to familial risk and resilience for suicidal behavior. Methods [ 11C]CUMI-101 PET imaging to quantify regional brain 5-HT1A receptor binding was conducted in individuals considered to be at high-risk for mood disorder or suicidal behavior on the basis of having a first or second degree relative(s) with an early onset mood disorder and history of suicidal behavior. These high-risk subjects were subdivided into: high-risk resilient having no mood disorder or suicidal behavior (HR-R, n=29); high-risk with mood disorder and no suicidal behavior history (HR-MOOD n=31); and high-risk with mood disorder and suicidal behavior (HR-SA/MOOD, n=25). Groups were compared to healthy volunteers without a family history of mood disorder or suicidal behavior (HV, n=34). Participants underwent the Trier Social Stress Task (TSST). All subjects were free from psychotropic medications at the time of the TSST and PET scanning. Results We observed no group differences in 5-HT1A receptor binding considering all regions simultaneously, nor did we observe heterogeneity of the effect of group across regions. These results were similar across outcome measures (BPND for all subjects and BPp in a subset of the sample), and definitions of regions of interest (ROIs; standard or serotonin system-specific ROIs). We also found no group differences on TSST outcomes. Within HR-SA/MOOD, lower BPp binding [β=-0.084, Standard Error or SE=0.038, p=0.048] and higher cortisol reactivity to stress [β=9.25, 95% CI (3.27,15.23), p=0.004] were associated with higher lethality attempts. There were no significant relationships between 5-HT1A binding and cortisol outcomes. Conclusions 5-HT1A receptor binding in ROIs was not linked to familial risk or resilience protecting against suicidal behavior or mood disorder although it may be related to lethality of suicide attempt. Future studies are needed to better understand the biological mechanisms implicated in familial risk for suicidal behavior and how HPA axis function influences such risk.

We carried out two studies to test the hypothesis that altered central serotonergic function, as assessed by lower prolactin (PRL) response to fenfluramine (D-FEN), is more closely associated with suicidal behavior than a particular psychiatric diagnosis. A D-FEN test was performed in 85 major depressed inpatients, 33 schizophrenic inpatients, and 18 healthy controls. We showed that PRL response to D-FEN is a marker of suicidality, regardless of psychiatric disorder. We then examined the association en the serotonin (5-hydroxytryptamine) receptor 5-HT(2A) gene polymorphism (T102C) and suicide in a sample of Brazilian psychiatric inpatients (95 with schizophrenia, 78 with major depression) and 52 healthy controls. No differences were found in genotypic frequencies across patients and controls. Overall, no differences were found between patients with (n=66) and without (n=107) a history of suicide attempt. We also compared patients with a history of severe suicide attempts (lethality>3; n=32) and patients without such a history (n=107), but they did not exhibit different genotypic frequencies either. These results show thai the 5-HT(2A) gene polymorphism (T102C) may not be involved in the genetic susceptibility to suicidal behavior.

Prior research has shown that psychopathic personality traits are differentially related to suicide risk, and limited literature also suggests the potential that such risk manifests differently across sex. The current study sought to examine whether sex moderated associations between domains from the triarchic model of psychopathy, a comprehensive perspective of psychopathy, and various suicide variables. Our sample included 1,064 criminal defendants (760 males, 304 females), who had been administered the MMPI-2-RF, from which triarchic psychopathy scales were scored. Suicide-related variables, including current suicidal ideation during interview, history of previous suicide attempts, and number of previous suicide attempts, were reliably obtained from clinical records. The MMPI-2-RF SUI (Suicide/Death Ideation) scale was also examined as a psychometric operationalization of suicidality. Results provided evidence for the general association between psychopathy-related traits and suicide-related outcomes in a manner consistent with the literature. However, these associations did not differ as a function of sex.

Background: Suicide is a major cause of mortality for patients with eating disorders (ED), especially for patients with anorexia nervosa. Attempted suicide is also relatively common in patients with anorexia or bulimia nervosa. Aims: This study aimed at examining associations between attempted suicide and trait- and state-dependent characteristics in a large clinical population of ED patients. Method: The sample consisted of 1,436 in- and outpatients of the Centre for Eating Disorders of the Ghent University Hospital. Measures of ED symptoms, psychopathology, and personality traits were compared between ED patients with and ED patients without a history of attempted suicide. Results: A history of attempted suicide was found in 11.8% of the ED patients and lifetime suicidal ideation was reported by 43.3%. Multivariate analyses showed that a history of attempted suicide was associated with higher scores on depression, purging symptomatology, early-developed cognitive schemes (impaired autonomy and increased inhibition), and social insecurity. Conclusion: These findings support the increased risk of suicidal behavior in ED. The presence of particular personality traits, of cognitive schemes, and of purging and depressive symptoms should increase vigilance for suicidal behavior.
