Clinical rating scales in suicide risk assessment

This study explores the usefulness of clinical rating scales in the assessment of suicidal risk in an urban psychiatric teaching hospital. Admission for clinically evaluated suicide risk was the outcome variable because actual suicide occurs rarely. Six clinical scales identified high-risk patients: the Modified SAD PERSONS scale, revised Beck Depression Inventory, Beck Anxiety Inventory, Beck Hopelessness Scale, Beck Scale for Suicidal Ideation (BSS), and the High-Risk Construct Scale (NEW). It was hypothesized that patients who scored highly on the clinical scales were more likely to be admitted. Five of the scales had previously established psychometric properties, while one was new and untested. For our patient population, the established scales had 100% sensitivity and negative predictive value, but lower specificity and positive predictive value (range = 38–90% & 28–71%). We performed a correlation matrix and regression analysis to determine which scale(s) best predicted admission based upon suicidal concerns. The previously untested NEW scale was the best predictor followed by the BSS. Clinical rating scales cannot predict suicide in the individual and strict cut-off scores should not be used to dictate admission to hospital. However, the information provided can be a valuable adjunct to suicide risk assessment in psychiatric and non-psychiatric emergency settings

Correlates of suicide and violence risk 1: the suicide risk measure

A measure of suicide risk was developed using items reported to discriminate suicidal patients from controls in various studies. The new self-report scale was administered to 82 outpatients, 157 inpatients, and 83 college students. Using total scores, significant differences were found between the college sample and the two patient samples. The scale also discriminated between patients who reported one or more past suicide attempts and those who reported none. An independent cross-validation showed that half of the items continued to discriminate between patient and control groups. Sensitivity and specificity estimates were also determined. The test does not attempt to predict a specific rare event, i.e., suicide. It attempts to describe the degree to which a given individual reveals a set of characteristics that are similar to a suicide prototype.     

Survival analysis of suicide risk after attempted suicide

Survival analysis of suicide risk by sex and age after attempted suicide was studied in a cohort of 1573 suicide attempters referred to the psychiatric emergency room at the Karolinska Hospital from 1981 to 1988. The time course of suicide risk and the overall prognosis after attempted suicide and, in particular, the possible usefulness of sex and age as risk factors for the prediction of suicide risk after attempted suicide was analyzed. Nearly two thirds of the sample were women and most of the suicide attempters were young (in their twenties and thirties), and the median age was 35 years. The overall mortality after a 5-year mean observation period after attempted suicide was 11%, and the suicide mortality was 6 %. The suicide risk after attempted suicide among men (8.3%) was nearly twice the female suicide risk (4.3%). Age as a possible suicide risk factor was analyzed for each sex separately by median split subgrouping. It was concluded that both older and younger male suicide attempters are at high risk of suicide (7% and 10% respectively), and older women are at higher risk than younger (6%, vs 2%). The suicide risk is particularly high during the first year after the suicide attempt. The high suicide risk group of young adult male suicide attempters is one of the main feasible targets of psychiatric intervention research programs on suicidal behavior. Suicide among young men is a major cause of years of life lost.     

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.     

The effect of perceived burdensomeness and thwarted belongingness on therapists' assessment of patients' suicide risk

Objective: The interpersonal theory of suicide posits that perceived burdensomeness and thwarted belongingness are two causal interactive suicidal risk factors. The aim of this study was to examine whether therapists are affected by these factors upon assessing patients' suicide risk. Method: Using an experimental design, 388 mental health professionals were presented with a text vignette describing a hypothetical patient with either high or low perceived burdensomeness and with either high or low thwarted belongingness. Results: The findings revealed that both factors affected therapists' risk assessment of psychache, suicidal ideation, suicide attempt and resilience. Conclusions: The study results highlight the interpersonal theory as an important theory for understanding the factors upon which therapists and mental health professionals rely when assessing suicide risk.     

Attempted suicide predicts suicide risk in schizophrenia spectrum psychosis

Background: People with schizophrenia have an increased risk of suicide and attempted suicide is suggested to be an important risk factor. Aim: Our objective was to assess the cumulative survival, predictive values and odds ratios of attempted suicide for suicide in a long-term cohort of patients with schizophrenia spectrum psychosis with and without previous attempted suicide. Method: Inpatients (n=224) hospitalized with schizophrenia spectrum psychosis were followed for a mean of 25 years. All patients were followed up for causes of death. Information on suicide attempt before the end of the observation period was retrieved from medical records. Results: Eight percent died by suicide during the follow-up. Eighteen percent of suicide attempters died by suicide. Two percent of non-attempters died by suicide. There was a strong association between previous suicide attempt and suicide in men and women. Odds ratio for attempters vs. non-attempters was 10. Suicide risk was almost three times higher in male than female suicide attempters. Conclusion: Previous attempted suicide is an important risk factor for suicide in both men and women with schizophrenia spectrum psychosis, particularly in male suicide attempters. The suicide risk remains high over a long period. Continuous assessment of risk factors and appropriate treatment are crucial for this patient group to prevent suicide.     

Preventive strategies and program evaluation methods for chronically mentally ill suicide attempters

In the course of defining treatment strategies and outcome criteria for a case management program serving the chronically mentally ill we reviewed the medical records of 282 patients admitted to University Hospital in Portland, Oregon following suicide attempts in 1979 and 1980. We found that these young people often had chronic psychiatric disorders, usually overdosed on medications, and spent a short time in the hospital—frequently in the intensive care unit. A substantial percentage of patients were clustered in the dowtown area of Portland and had not been treated previously at our hospital. Based on these findings we suggest a community based primary prevention program emphasizing case management for the chronically mentally ill. We also discuss a secondary prevention strategy in which overdose morbidity is minimized by adopting a cautious approach to dispensing psychotropic medications. We point out that readily available data on health care utilization following suicide attempts can be used to monitor such a program's effectiveness.     

Relationship of optimism and suicidal ideation in three groups of patients at varying levels of suicide risk

Optimism has been associated with reduced suicidal ideation, but there have been few studies in patients at high suicide risk. We analyzed data from three study populations (total N = 319) with elevated risk of suicide: (1) patients with a recent acute cardiovascular event, (2) patients hospitalized for heart disease who had depression or an anxiety disorder, and (3) patients psychiatrically hospitalized for suicidal ideation or following a suicide attempt. For each study we analyzed the association between optimism (measured by the Life–Orientation Test-Revised) and suicidal ideation, and then completed an exploratory random effects meta-analysis of the findings to synthesize this data. The meta-analysis of the three studies showed that higher levels of self-reported optimism were associated with a lower likelihood of suicidal ideation (odds ratio [OR] = .89, 95% confidence interval [CI] = .85−.95, z = 3.94, p < .001), independent of age, gender, and depressive symptoms. This association held when using the subscales of the Life Orientation Test-Revised scale that measured higher optimism (OR = .84, 95% CI = .76−.92, z = 3.57, p < .001) and lower pessimism (OR = .83, 95% CI = .75−.92], z = 3.61, p < .001). These results also held when suicidal ideation was analyzed as an ordinal variable. Our findings suggest that optimism may be associated with a lower risk of suicidal ideation, above and beyond the effects of depressive symptoms, for a wide range of patients with clinical conditions that place them at elevated risk for suicide.     

The suicide assessment scale: an instrument assessing suicide risk of suicide attempters.

The Suicide Assessment Scale (SUAS), a scale constructed to measure suicidality over time, was administered to 191 suicide attempters. Its predictive validity was tested. SUAS ratings were compared to ratings from other scales, and related to age and psychiatric diagnoses including co-morbidity. Eight patients committed suicide within 12 months after the SUAS assessment. Apart from advanced age, high scores in the SUAS were significant predictors of suicide. From a receiver operating characteristic (ROC) analysis, we identified cutoff SUAS scores which alone and in combination with certain diagnostic and demographic factors are of apparent value in the clinical evaluation of suicide risk after a suicide attempt.     

Coping styles and suicide risk

A total of 30 psychiatric in-patients admitted because of suicidal behaviour were compared with 30 non-suicidal psychiatric in-patients and 32 healthy controls on measures of suicide risk and coping styles. The three groups were similar with regard to demographic variables, but the suicidal group scored higher on the suicide risk scale. Suicidal patients were significantly less likely to use the coping styles of minimization and mapping. They were unable to de-emphasize the importance of a perceived problem or source of stress. They also lacked the ability to obtain new information required to resolve stressful life events. Four coping styles correlated negatively with the suicide risk (minimization, replacement, mapping and reversal), while another three (suppression, blame and substitution) correlated positively. These findings may have important implications for therapists and primary prevention workers, and might pave the way towards recognition of the role played by coping styles in predicting suicide and its use for cognitive intervention in these high-risk patients.     

Sex differences in risk factors for suicide after attempted suicide

Abstract.Aim: This study aims to investigate suicide risk factors after attempted suicide and whether and how these risk factors differ between the sexes.Method: A total of 1052 suicide attempters admitted to the Medical Emergency Inpatient Unit, Lund University Hospital, Sweden were followed up concerning suicide and death from other causes after a median period of 6 years and 5 months. In all, 50 persons committed suicide during follow-up. At the index suicide attempt, socio-demographic data and information about clinical characteristics were gathered in a standardised manner. Risk factors were identified among these data using survival analyses for the whole sample and for each sex separately.Result: Men had a higher frequency of suicide and a greater overall mortality than women. Cox regressions showed that suicide attempt(s) prior to the index attempt and the use of a violent method for the index attempt were risk factors for men only, whereas older age and a high suicidal intent (Beck SIS score) were female ones. Major depression was a risk factor for both sexes.Conclusion: More attention probably needs to be paid to the importance of gender in assessment of suicide risk and treatment of suicide attempters.     

Somatic symptoms and risk of suicide

We investigated the occurrence and significance of somatic symptoms in the process leading up to suicide. The material consisted of all individuals who had committed suicide (n=108) in the province of Kuopio during the Finnish National Suicide Prevention Project. Methods of study included semi-structured interviews with workers who had last treated the suicide victim, and consensus case reports based on psychologic autopsy. Nearly half (44%) of the suicide victims, particularly men, had complained of somatic symptoms during their last treatment contact. Seventy-four per cent had contacted health or social services during the month immediately before suicide. Suicide was usually a surprise to workers. Most (79%) of the individuals studied had experienced a marked loss before suicide. More than half of the losses (69%) had occurred during the preceding year. Immediately before suicide, some depressed individuals found it difficult to talk about their depression and the losses that have led to it. They often complain about somatic symptoms instead. Such complaints may be associated with an acute risk of suicide. Awareness of the fact that psychologic and somatic symptoms are connected could facilitate identification of acute risk of suicide and planning of emergency help for and treatment of a patient.     

Smoking and the risk of suicide

OBJECTIVE: To estimate the relationship between cigarette smoking and the risk of suicide. METHOD: The mortality of 36527 adult men and women was monitored for the mean 14.4 years. Information on deaths caused by suicide was obtained from the National Mortality Register. Suicides were subclassified by the level of violence used. Current smokers of 1-20 cigarettes per day were considered light/moderate smokers and heavy smokers were defined as those smoking > or =21 cigarettes per day. RESULTS: There were 134 suicides among 17798 men and 31 suicides among 18729 women. The most common suicide methods were hanging, firearms and drug overdose. According to the Cox model the adjusted relative risk of both violent and non-violent suicide was significantly and linearly increased among light/moderate and heavy smokers compared with non-smokers. CONCLUSION: Smoking was associated with an increased risk of suicide irrespective of the level of violence used.
