Physiological Reactions to a Suicide Film: Suicide Attempters,Suicide Ideators,and Nonsuicidal Patients

A film about two teenagers who commit suicide was shown to three groups of psychiatric inpatients: 17 who had attempted suicide, 20 who had expressed suicidal thoughts, and 10 who were not suicidal. Anxiety before and after the film was evaluated with psychometric (anxiety rating scale) and physiological tools (heart and respiration rate, blood pressure, electromyogram). Values noted before and after screening, and the degree of change in these values, were compared. In addition, psychomotor agitation was rated at several points during the film. Most results were negative. The suicide attempters had significantly lower postscreening heart rates and a significantly lesser change in heart and respiration rates than the other two groups. The suicide attempters revealed an increase in psychomotor agitation until the discovery of the suicide and a decrease thereafter, whereas the agitation of the nonsuicidal patients continued to increase from the start to the end of the film. The study suggests that on some parameters, suicide attempters reveal less anxiety than nonsuicidal psychiatric patients following exposure to a simulated suicide. The reaction of suicide ideators falls somewhere between the two groups.     

Mental Disorders,Comorbidity, and Pre‐enlistment Suicidal Behavior Among New Soldiers in the U.S. Army: Results from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS)

We examined the associations between mental disorders and suicidal behavior (ideation, plans, and attempts) among new soldiers using data from the New Soldier Study (NSS) component of the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS; N = 38,507). Most new soldiers with a pre‐enlistment history of suicide attempt reported a prior mental disorder (59.0%). Each disorder examined was associated with increased odds of suicidal behavior (ORs = 2.6–8.6). Only PTSD and disorders characterized by irritability and impulsive/aggressive behavior (i.e., bipolar disorder, conduct disorder, oppositional defiant disorder, and attention‐deficit/hyperactivity disorder) predicted unplanned attempts among ideators. Mental disorders are important predictors of pre‐enlistment suicidal behavior among new soldiers and should figure prominently in suicide screening and prevention efforts.     

Depressed mood: The role of negative thoughts,self-consciousness,and sex role stereotypes

Research typically finds that depression is twice as common among women as among men. This may relate to differences in socialization that result in different emotions, cognitions, and coping reactions. Sex-role stereotypes, employment and marital status, and differential social pressures may also be significant in making women more vulnerable to the development of depression. Women may have less decision-making power, face more adverse life events, and have limited access to resources, which may lead to feelings of helplessness and low self-esteem. Low self-esteem and negative cognitions about the self in turn may be proximal factors predictive of negative mood. Additionally, women may be more prone to ruminative self-focus rather than active coping, a significant risk factor for depression. This study examined individual predictors of depressed mood for each sex, including coping, self-esteem, negative thoughts, self-consciousness (rumination), as well as social factors such as the endorsement of sex-role stereotypes and decision-making power in the family. Results indicated that social factors were not related to depressed mood in either sex, but were related to coping styles and self-esteem. Depressed mood was associated with individual characteristics, such as avoidant coping styles, social anxiety for women, and ruminative self-focus for men. Regression analysis showed that coping through denial and negative thoughts explained depressed mood, and the latter was particularly true for men. These results point to the significance of examining both individual and social factors when attempting to understand depression in men and women.     

When more is not merrier: shared stressful experiences amplify

ABSTRACT

Sharing experiences with others, even without communication, can amplify those experiences. We investigated whether shared stressful experiences amplify. Participants completed the Cold Pressor Task at the same time as a confederate, or while the confederate completed another task. Importantly, participants in the shared (vs. unshared) condition experienced more sensory pain characteristics and reported more stress over time in relation to the task. Importantly, they reported thinking more about the confederate’s thoughts and feelings. This mentalizing sometimes mediated effects, suggesting the task amplified when participants constructed mental representations of others’ CPT experience (e.g. that it hurts) and incorporated it into their own responses.     

British and Pakistani children's understanding of death: Cultural and developmental influences

This study explored British and Pakistani 4‐ to 7‐year‐olds’ (N = 188) understanding of death. The aim was to examine possible influences on the acquisition of the subcomponents of the death concept by investigating how they are understood by children of different ages and cultural and religious backgrounds. Three groups of children were compared: White British and British Muslim living in London, and Pakistani Muslim living in rural Pakistan. In line with previous research (Slaughter, 2005, Aust. Psychol., 40(3), 179), irreversibility of death was one of the first subcomponents to be acquired, while causality was the last. The two groups of British children shared many similarities in their understanding of inevitability, applicability, irreversibility, and cessation. Pakistani Muslim children understood irreversibility earlier than did children in both British groups. In all three cultural groups, children's responses demonstrated very limited understanding of causality. Our findings support the view that aspects of a mature understanding of death develop between the ages of 4 and 7 years and that the process of understanding death as a biological event is, to a great extent, universal. They also suggest that aspects of children's reasoning are influenced by culturally specific experiences, particularly those arising from living in rural versus urban settings.
