A Call for Research: The Need to Better Understand the Impact of Support Groups for Suicide Survivors

Support groups for suicide survivors (those individuals bereaved following a suicide) are widely used, but little research evidence is available to determine their efficacy. This paper outlines the pressing public health need to conduct research and determine effective ways to identify and meet the needs of suicide survivors, particularly through survivor support groups. After describing the various approaches to survivor support groups, we explain the need for further research, despite the inherent challenges. Finally, we pose several questions for researchers to consider as they work with survivors to develop a research agenda that sheds more light on the experiences of survivors and the help provided by survivor support groups.     

Development of a Chinese Version of the Suicide Intent Scale

This study established the psychometric properties of the Chinese version of the Suicide Intent Scale (SIS) in a clinic‐ and community‐based sample of 36 patients and 592 respondents, respectively. Results showed that the Chinese SIS demonstrated good inter‐rater and test‐retest reliability. Factor analysis generated three factors (Precautions, Planning, and Seriousness) explaining 92.9% of the total variance with high internal consistency. It was moderately correlated with depressive symptoms. Results suggest that the Chinese SIS is a reliable and valid instrument for use in assessing the extent of suicidal intention among subjects with deliberate self‐harm in ethnic Chinese populations.     

Predictors of Multiple Suicide Attempts among Suicidal Black Adolescents

Psychopathology, social support, and interpersonal orientation were studied in relation to suicide attempt status in acutely suicidal, psychiatrically hospitalized Black adolescents and a matched sample of White adolescents. In the total sample, multiple attempters were differentiated by lower perceived support. Within the Black youth subsample, social comparison and positive stimulation from others differentiated multiple attempters from single attempters/ideators. Only suicidal ideation predicted multiple attempts among White youth and only higher interpersonal orientation predicted multiple suicide attempts within Black adolescents.     

Suicidality in a Sample of Arctic Households

We investigated the association of suicidal ideation and behavior with depression, anxiety, and alcohol abuse in a Canadian Arctic Inuit community. Inuit (N = 111) from a random sample of households completed assessments of anxiety and depression, alcohol abuse, and suicidality. High rates of suicidal ideation within the past week (43.6%), and suicide attempts within last 6 months (30%), were reported. Ideation was more frequent among younger persons, whereas those favoring local native language were less likely to report a wish to die. Higher overall suicidality scores were associated with higher anxiety, and alcohol abuse, but not with depression or gender. Implications for future research are discussed.     

Parental Responsibility and the Morality of Selective Abortion

It is now a common opinion in Western countries that a child's impairment would probably place an unexpected burden on her parents, a burden that the parents have not committed themselves to dealing with. Therefore, selective abortion is in general a morally justified option for the parents. I argue that this view is based on biased information about the quality of life of individuals with impairments and their families. Also, a conscious decision to procreate should bring about conscious assent to assuming obligations as a parent. This implies a duty of caring for any kind of child. Consequently, if the child's condition is not such that it would make its life not worth living, and if the parents live in an environment where they are able to provide their child and themselves an adequate well-being, they do not have a morally sufficient reason to terminate the pregnancy on the grounds of fetal abnormality.     

Fractal dynamics of heart beat interval fluctuations in corticotropin-releasing factor receptor subtype 2 deficient mice

Non-linear fractal analysis of cardiac interbeat time series was performed in corticotropin-releasing factor receptor subtype 2 (CRFR2) deficient mice. Heart rate dynamics in mice constitutes a self-similar, scale-invariant, random fractal process with persistent intrinsic long-range correlations and inverse power-law properties. We hypothesized that the sustained tachycardic response elicited by intraperitoneal (ip) injection of human/rat CRF (h/rCRF) is mediated by CRFR2. In wildtype control animals, heart rate was increased to about maximum levels (~ 750 bpm) while in CRFR2-deficient animals baseline values were retained (~ 580 bpm). The tachycardic response elicited by ip-application is mediated by CRFR2 and is interpreted to result from sympathetic stimulation. However, the functional integrity of CRFR2 would not present a prerequisite to maintaining the responsiveness and resiliency of cardiac control to external environmental perturbations experimentally induced by extrinsic ip-application of h/rCRF or under physiological conditions that may be associated with an increased peripheral release of CRF. Under stressful physiological conditions achieved by novelty exposure, CRFR2 is not involved in the cardiodynamic regulation to external short-term stress. While the hypothesis of involvement of CRFR2 in cardiac regulation upon pharmacological stimulation cannot be rejected, the present findings suggest that the mechanism of action is by sympathetic stimulation, but would not unambiguously allow to draw any conclusions as to the physiological role of CRFR2 in the control of cardiac dynamics.
