Premenstrual symptoms and luteal suicide attempts

Abstract. Objective: If premenstrual symptoms (PMS) are temporally and specifically associated with suicidal attempts, suicide attempts in women with PMS should occur more frequently in the luteal phase. Method: In a general hospital, 125 fertile female suicide attempters (and 83 blood donors as controls) with regular menstrual cycles were prospectively studied. A retrospective DSM-IV diagnosis of Premenstrual Dysphoric Disorder (PMDD) was made. Results: Attempts during the luteal phase were not more frequent in females with PMDD (34%,23/68) than in those without PMDD (35%, 20/57). The sample had enough power to detect medium and large effect sizes. As expected, there was a significantly higher frequency of PMDD in suicide attempters than in the controls (54% vs 6%; Fishers exact test, p 0.001). Conclusion: This study was limited by the use of retrospective PMDD diagnosis but suggests that PMDD may not be associated with suicidal acts during the luteal phase,when PMS are present.     

Inverse association between serum albumin and depressive symptoms among drug-free individuals with a recent suicide attempt

Abstract

Background and aim: Albumin is a protein with multifaceted functions in the human body. According to many studies, lower serum albumin may be associated with depression in various groups of psychiatric and non-psychiatric patients, as well as with attempted suicide. As more severe depressive symptoms have been identified as a reliable risk factor for suicide in patients with high suicide risk, it would be of interest to study whether, the inverse association between depressive symptoms and albumin may exist among patients with attempted suicide. Therefore, the aim of the study was to investigate the possible association between albumin and depressive symptoms among individuals who recently attempted suicide.

Methods: One-hundred twenty-seven individuals with a recent suicide attempt were involved in the study between 1987 and 2001. Albumin was analyzed in serum. Patients were evaluated with the Comprehensive Psychopathological Rating Scale (CPRS) from which the Montgomery-Åsberg Depression Rating Scale (MADRS) and the item assessing Apparent sadness were derived.

Results: Only among patients aged ≥45, serum albumin levels were significantly and negatively correlated with total scores of MADRS and the item Apparent sadness (all p values <.00625).

Conclusions: Our findings indicate an inverse association between serum albumin and the severity of depressive symptoms in individuals who attempted suicide, older than 45 years.     

Differences between adolescent suicide attempters and depressed adolescents.

Most of the characteristics differentiating between adolescent attempters and nonattempters do not have discriminative power in comparing 48 adolescents who recently attempted suicide with 66 depressed adolescents. These characteristics may probably be attributed to an affective disorder that is present in most of the suicide attempters. However, suicide attempters, compared with the depressed group, live in more problematic circumstances (such as family disruption or sexual abuse) and have a cognitive style that promotes a more negative evaluation of events and situations. Their depressive symptoms are distinguished from the depressed group by withdrawal and isolation, besides maintaining a hopeless and negative expectation of the future. Furthermore, there are reasons to accept the idea that suicidal behavior is a serious alternative within their behavioral repertoire. Based on these findings, a psychological interpretation is given concerning the dynamics leading to a suicide attempt. Also, intervention strategies are discussed.     

The prevalence of aborted suicide attempts among psychiatric in-patients

We report the prevalence of aborted suicide attempts in which the essential characteristics are (i) intent to kill oneself, (ii) a change of mind before making an actual suicide attempt and (iii) the absence of physical injury. The lifetime history of aborted suicide attempts was assessed by semi-structured interview of 733 patients, aged 18–59 years, who were consecutively admitted to a psychiatric hospital. In the study group, 46% of subjects had made a suicide attempt and 29% had made at least one aborted attempt during their lifetime. Subjects who had made aborted attempts were more likely to have made actual attempts. Approximately 11% of the subjects in the study group had a history of aborted attempts of potential high lethality, such as going to a height in order to jump, or holding a gun to the head. There were no major demographic differences between those with and without a history of aborted attempts. However, among those with no prior history of actual attempts, subjects with depression and a family history of suicide were more than twice as likely as those without such a history to have made an aborted attempt. Aborted suicide attempts are a common suicidal behaviour among psychiatric in-patients. Whether they predict actual attempts or suicide warrants prospective investigation.     

Age-specific characteristics of attempted suicide in adolescence

A total of 422 suicide attempts of adolescents (15 to 19 years of age) were investigated and compared with 327 suicide attempts of young adults. Adolescents had more serious social problems than young adults. Their adaptive problems became worse while growing older until the age of 20. Adolescents made suicide attempts with serious intent more often than young adults, but their suicide attempts were not as often lethal as in young adults. Although repeated suicide attempts were relatively common in both groups, only 10 people were part of both materials. Adolescents were as often psychotic when attempting suicide as young adults were. Twenty-four percent of adolescents and 26% of young adults were admitted to a psychiatric hospital as treatment.     

Two subtypes of adolescent suicide attempters

An empirical classification of 203 adolescent suicide attempters (mean age 17.3) was achieved using multiple correspondence analysis. The characteristics upon which the classification is based concern sociodemographic as well as psychological variables. Two groups are identified: the first is predominantly characterized by recent problematic behaviors, whereas the second group is primarily characterized by problematic circumstances. Analyzing related variables, the first group seems to have special clinical and preventive interest, because of its high risk for recidivism. The second group seems to have a satisfactory level of functioning.     

The familial aggregation of adolescent suicide attempts

The objective of this study was to determine whether the familial aggregation of suicidal behaviour is explained by the familial aggregation of personality disorder and aggression. The relatives of 62 clinically referred adolescent suicide attempters were compared with 70 never-suicidal psychiatric controls. The first-degree relatives of the suicide attempters had a higher rate of suicide attempts/completion than those of the psychiatric controls. This rate remained significantly higher after controlling for Axis I and II differences in the probands and the relatives, but familial personality disorder was significantly associated with suicidal risk in probands. Among the adolescent attempters, high scores on a measure of assaultiveness were associated with significantly higher familial rates of suicide attempts/completion. Our results support the hypothesis that suicidal behaviour may be transmitted as a trait independent of Axis I and II psychopathology but that, in addition, personality disorder has a role in the transmission of suicidal behaviour. An interrelationship between proband assaultiveness and the familial aggregation of suicidality was noted.     

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

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

Risk factors associated with suicide attempt in young French people

Demographic data, personal and familial characteristics, as well as DSM-III-R-based psychiatric diagnoses were collected in 369 adolescents and young adults aged between 15 and 29 years, referred to an Emergency Department for psychological problems. In total, 60% of them were suicide attempters. Separations before the age of 12 years and depression in the family emerged as the main features distinguishing the suicidal group from the psychiatric control group. Fifty per cent of suicide attempters were repeaters. Fostering during childhood, suicide attempts and depression in the family were found to be risk factors for repeated self-attempts. These results support the view that significant levels of dysfunction, together with increased psychiatric morbidity, especially suicidal behaviour, characterize the families of young self-attempters.     

Evaluation of clinical prognostic models for suicide attempts after a major depressive episode

Objective: In this study, we compare the performance of prognostic models of increasing complexity for prediction of future suicide attempt. Method: Using data from a 2‐year prospective study of 304 depressed subjects, a series of Cox proportional hazard regression models were developed to predict future suicide attempt. The models were evaluated in terms of discrimination (the ability to rank subjects in order of risk), calibration (accuracy of predicted probabilities of attempt), and sensitivity and specificity of risk group stratification based on cross‐validated predicted probabilities. Results: Although an additive model with past attempt, smoking status, and suicidal ideation achieved 75% (cross‐validated) sensitivity and specificity, models that performed best in terms of discrimination included interactions between predictor variables. Conclusion: As several models had similar predictive power, clinical considerations and ease of interpretation may have a significant role in the final stage of model selection for assessing future suicide attempt risk.     

Attempted suicide predicts suicide risk in mood disorders

Suicide risk was studied in a sample of 346 mood disorder inpatients, 92 of whom were admitted after a current suicide attempt. The overall suicide mortality after a mean observation period of 6 years was 8%. The potential of attempted suicide to predict suicide risk in hospitalized patients with mood disorders was studied by survival analysis after subgrouping on the basis of whether a current suicide attempt had occurred or not. The suicide risk the first year after attempting suicide was 12% (11/92), compared with 2% (4/254) in the mood disorder subgroup with no current suicide attempt. The long-range suicide risk after a current suicide attempt in depression was 15% (14/92) as compared with 5% (13/254) among those without a current suicide attempt. It is concluded that a current suicide attempt in mood disorder inpatients predicts suicide risk particularly within the first year and should be taken very seriously.     

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.     

Personality disorder and suicide intent

Studies of suicide intent have found a link between seriousness of the attempt and personality. Following a parasuicide, 60 patients were assessed using measures of depression, suicide intent and personality. Personality disorder was found to be present in over 65% of these and was mainly of explosive type. It was significantly more common in men than women and the dimension measuring sociopathy was equivocally linked to male gender. There were no other associations between gender and the other dimensions measured. Using a categorical approach to personality, suicide intent was not significantly different between the categories of personality; there was no correlation between dimensional or categorical measures of personality and suicide intent, when the severity of depression was controlled. By itself personality did not contribute significantly in determining variance in intent but it did interact significantly with age.     

Adolescent suicide attempts: sex differences predicting suicide

Four hundred and twenty-two consecutive hospitalized suicide attempts made by 15-19 year old girls and boys in Helsinki area were investigated. One hundred and twenty suicide attempts were made by 115 boys and 302 by 247 girls. Differences between sex were analyzed. Boys had more severe adaptive problems. Their overall level of functioning was poorer than was that of the girls. Their physical health was not as good as that of the girls. Boys did not carry out more severe suicide attempts as concerns the estimated lethality and intent of the attempt, but their suicide attempts seemed to be connected with more severe physical, mental and social problems. Boys were more susceptible to alcohol provoked suicidal behaviour than girls, and they presented less appealing motives. The outcome of the boys was much worse than the outcome of the girls. Risk ratio for suicide during the 5-year follow-up was 2.0 for boys and 0.55 for girls. Risk ratio concerning violent death was 2.43 for boys and 0.33 for girls. Young male adolescents attempting suicide should be taken very seriously as a risk group for subsequent suicide.

Suicide and violent death among adolescent suicide attempters

A total of 422 subsequent suicide attempts commited by 362 people 15-19 years old in the Helsinki area in 1973-1982 were investigated to find risk factors for subsequent suicide or violent death. By the end of 1982, 8.7% of 115 boys and 1.2% of 247 girls had died. Eight (2.2%) had committed suicide. The mean annual mortality for suicide and violent death was 20-fold compared with the mortality for suicide and violent death among people 15-19 years old in Finland at that time. The risk ratios of the boys for suicide (2.0) and for violent death (2.4) were greater than that of the girls (0.6 and 0.3 respectively). The risk ratio of psychotic persons for suicide was 4.2 and for violent death 4.1. Seriousness of intent heightened the risk, whereas degree of lethality did not influence it. The people who expressed clear-cut difficulties as a reason for their suicide attempt seemed to have a smaller risk for suicide or violent death than people whose reasons remained unclear. Attempted suicide among boys is a serious symptom for predicting subsequent suicide that should be addressed in suicide prevention.     

The outcome of adolescent suicide attempts

A sample of 265 adolescents hospitalized between 1971 and 1980 in a psychiatric unit following a suicide attempt was studied to evaluate outcome. After an average of 11.5 years, 48% of the original sample, or 127 subjects, could be traced. Thirty-nine per cent of these subjects showed signs of improvement, 22% appeared to be unchanged and 33% were worse. Substantial dropout rates were found in postdischarge care, only 32% of the patients having been followed up for a sufficient amount of time. Fifteen subjects had died, only one of whom from a natural cause. Of the remaining 14, 5 had committed suicide and 9 had died from unnatural or violent causes other than suicide, the cause of death appearing in all cases to be closely linked to the subject's adolescent disorders. The implications of these findings for suicide prevention are discussed.
