High Rates Of Suicidal Behavior Research Articles

Suicidal behavior in patients with schizophrenia and other psychotic disorders.

Patients with schizophrenia are known to be at high risk for suicide attempts and dying by suicide. However, little research has been conducted to determine whether the risk for suicidal behavior is elevated among patients with psychosis in general. This study evaluated 1-month and lifetime rates of suicidal behavior among 1,048 consecutively admitted psychiatric inpatients (ages 18 to 55 years) with DSM-III-R psychotic disorders. Demographic, clinical, and diagnostic correlates of suicidal behavior were examined. A high rate of suicidal behavior was found in the group: 30.2% reported a lifetime history of suicide attempts, and 7.2% reported a suicide attempt in the month before admission. The highest 1-month and lifetime rates were found in patients with schizoaffective disorder and major depression with psychotic features. Ratings of the medical dangerousness of the most recent suicide attempt on the basis of the extent of physical injury were higher in patients with schizophrenia spectrum psychoses. Agreement was high between emergency room assessments and semistructured interview assessments of suicidal behavior. Rates of suicidal behavior were high across a broad spectrum of patients with psychotic disorders; patients with a history of a current or past major depressive episode (as a part of major depressive disorder or schizoaffective disorder) were at a greater risk for suicide attempts, but patients with schizophrenia, on average, made more medically dangerous attempts. Risk factors for suicidal behavior in patients with psychosis appear to vary compared to those for the general population.

On the role of neurobiological and genetic factors in the etiology and pathogenesis of suicidal behaviour among immigrants

Immigrants have higher rates of suicidal behavior than those in their countries of origin and their new countries. Immigration is a stressful life event which may lead to depression and suicidal behavior. Depressive disorders and suicidal behavior have a firm neurobiological and genetic basis. The author suggests that most immigrants who exhibit suicidal behavior in the new country had suicidal tendencies, and/or some degree of depression, and/or certain maladaptive personality traits in their countries of origin. The paper emphasizes the role of genetic and neurobiological factors in the human response to stressful events.

Women in cultural transition: suicidal behavior in South African Indian women.

Young South African Indian women are a population with relatively high rates of suicidal behavior. This article presents three illustrative case studies of nonfatal suicidal behavior by South African Indian women. The cases are discussed in relation to a review of epidemiological, historical, and sociocultural perspectives on South African Indian women. It is argued that suicidal behaviors in this group can be understood in the context of sociocultural transition. Transitional tensions between traditional Indian culture and Westernization have an impact on traditional gendered power relations and generate conflicts that have intrapsychic and interpersonal consequences for women and for men. These in turn may have adverse effects on marital functioning, quality of life, and specific aspects of emotional functioning, which have been identified as precursors of suicidal behavior. The case studies are discussed with reference to gender narratives. Implications for prevention, intervention, and future research are discussed.

Suicidal Behaviors and Childhood-Onset Depressive Disorders: A Longitudinal Investigation

In this longitudinal study, the rates and correlates of suicidal ideation and suicide attempts were determined among outpatient youths with depressive disorders and youths with other psychiatric disorders. At study entry, about 66% of the subjects evidenced suicidal ideation and 9% already attempted suicide. The rate of ideation remained fairly stable over time, whereas the rate of attempts reached 24% by the average age of 17 years. Major depressive and dysthymic disorders were associated with significantly higher rates of suicidal behaviors than were adjustment disorder with depressed mood and nondepressive disorders. In the presence of affective disorders, comorbid conduct and/or substance use disorders further increased the risk of suicide attempts.
