Suicide attempts and stressful life events among female victims of intimate partner violence living in poverty in Nicaragua

This article describes a study of 136 female intimate partner violence victims living in poverty in Nicaragua. The paper aimed to analyze the relationship between experiencing stressful life events (SLE) and perceived social support with suicide attempts, and to evaluate the differences in the SLE experienced by female suicide attempters versus non‐attempters. The results showed the existence of a high level of SLE among the interviewees, and that women who have attempted suicide have experienced substantially more of these events. Experiences of violence and less social support were especially related to suicide attempts among the interviewees.     

Load release balance test under unstable conditions effectively discriminates between physically active and sedentary young adults

This study investigates test-retest reliability and diagnostic accuracy of the load release balance test under four varied conditions. Young, early and late middle-aged physically active and sedentary subjects performed the test over 2 testing sessions spaced 1 week apart while standing on either (1) a stable or (2) an unstable surface with (3) eyes open (EO) and (4) eyes closed (EC), respectively. Results identified that test-retest reliability of parameters of the load release balance test was good to excellent, with high values of ICC (0.78–0.92) and low SEM (7.1%–10.7%). The peak and the time to peak posterior center of pressure (CoP) displacement were significantly lower in physically active as compared to sedentary young adults (21.6% and 21.0%) and early middle-aged adults (22.0% and 20.9%) while standing on a foam surface with EO, and in late middle-aged adults on both unstable (25.6% and 24.5%) and stable support surfaces with EO (20.4% and 20.0%). The area under the ROC curve >0.80 for these variables indicates good discriminatory accuracy. Thus, these variables of the load release balance test measured under unstable conditions have the ability to differentiate between groups of physically active and sedentary adults as early as from 19 years of age.     

What matters is the underlying experience: Similar motor responses during processing observed hand actions and hand-related verbs

It is well-accepted that processing observed actions involves at some extent the same neural mechanisms responsible for action execution. More recently, it has been forwarded that also the processing of verbs expressing a specific motor content is subserved by the neural mechanisms allowing individuals to perform the content expressed by that linguistic material. This view is also known as embodiment and contrasts with a more classical approach to language processing that considers it as amodal. In the present study, we used a go/no-go paradigm, in which participants were requested to respond to real words and pictures and refrain from responding when presented stimuli were pseudowords and scrambled images. Real stimuli included pictures depicting hand- and foot-related actions and verbs expressing hand- and foot-related actions. We, therefore, directly compared the modulation of hand motor responses during the observation of actions and the presentation of verbs, expressing actions in the same category. The results have shown that participants gave slower hand motor responses during the observation of hand actions and the processing of hand-related verbs as than observed foot actions and related verbs. These findings support embodiment showing that whatever the modality of presentation (observed action or verb), the modulation of hand motor responses was similar, thus suggesting that processing seen actions and related verbs shares common mechanisms most likely involving the motor system and the underlying motor experience.     

I Am So Happy ‘Cause My Friend Is Happy for Me: Capitalization,Friendship, and Happiness Among U.S. and Turkish College Students

ABSTRACT

Friends usually share positive events in their lives with each other. Referred to as capitalization, this process promotes individual happiness when the discloser perceives that the responses display genuine support. Yet, the specific mechanisms explaining why capitalization is associated with happiness are not known. The present study addresses this empirical issue by testing a mediational model positing that friendship quality would mediate the relationship between capitalization and happiness among U.S. and Turkish college students. Although the psychosocial well-being of the U.S. participants was significantly higher than Turkish participants, the proposed model was supported in both groups. This suggests that part of the reason capitalization is associated with happiness is because of friendship experiences. The authors also provide suggestions for future research.     

不同心理一致感初中生对压力的态度激活研究

该研究采用不同加工任务的间接测量方法,探讨不同心理一致感水平初中生对压力的外显认知倾向和内隐态度激活程度。结果表明:1)初中生较为稳定的积极认识和反应倾向在他们关于压力的外显认知加工中起了更为显著的作用;2)不同加工方式的虚惊率差异表明存在着初中生对压力情境的内隐态度,且这种无意识认知较为消极。     

Initial responses to the first dose of nicotine in novel smokers: The role of exposure to environmental smoking and genetic predisposition

Background: Sensitivity to initial smoking constitutes an early predictor of the risk of dependence. We investigated the role of exposure to smoking (by parents, siblings, and peers) and reward-related candidate gene polymorphisms (OPRM1 A118G, DRD2 TaqlA and DRD4?bp VNTR) in adolescents’ responses to initial smoking.

Methods: We used cross-sectional survey data and saliva samples from 171 Dutch students who had never inhaled on a cigarette (mean age: 13.9?years). The outcome measure was adolescents’ self-reported responses to initial smoking.

Results: Exposure to peer smoking was associated with increased liking (OR?=?1.74, CI?=?1.13–2.70) and more pleasant sensations (β?=?.21, p?=?.01). Exposure to maternal smoking was associated with less unpleasant sensations (β?=??.20, p?=?.01). Adolescents carrying the G-variant of the OPRM1 A118G polymorphism were more likely to report liking (OR?=?2.50, CI?=?1.09–5.73) and adolescents homozygous for the C-variant of the DRD2 TaqlA polymorphism reported less unpleasant sensations (β?=?.18, p?=?.04).

Conclusion: Although preliminary, these findings suggest that exposure to environmental smoking and polymorphisms in the OPRM1 and DRD2 gene may affect initial sensitivity to nicotine, an early phenotype of the risk of dependence. In the future, collaborative efforts to combine data from multiple studies in meta-analyses are needed to improve accuracy of estimated effects in genetic studies.     

Using stressful films to analyze risk factors for PTSD in analogue experimental studies – which film works best?

Abstract

To understand mental disorders, analogue paradigms provide an indispensable contribution. In posttraumatic stress disorder (PTSD), the stressful film paradigm is a frequently used analogue approach: Films depicting traumatic events are shown to non-clinical participants in order to elicit stress responses analogue to responses to traumatic events in real life. Previous studies used a large variety of films, which is problematic with regard to the comparability of results. The main goal of this study was to identify a film clip that (a) consistently provokes stress reactions and (b) provokes reactions that are as similar as possible to traumatic stress.

We randomly exposed 105 male and female participants to one of four stressful films, differing, e.g., in content and origin. Intrusive memories of the film, reported immediately after the film and during a diary phase of three days, as well as distress, heart rate, and several mood states were measured. A film clip depicting rape elicited the most consistent reactions that were characterized by a higher heart rate, more distress and more intrusive memories, compared to the other three clips. Intrusive memories across all films were especially related to an increase in heart rate and disgust in response to the film.     

Are Specific Emotion Regulation Strategies Differentially Associated with Posttraumatic Growth Versus Stress?

Extremely few studies have examined emotion regulation strategies as predictors of posttraumatic growth (PTG). This study aimed to examine several specific emotion regulation strategies, along with meaning making, as predictors of PTG, as opposed to posttraumatic distress. Participants were 107 adult women who had experienced a very stressful or traumatic event within the past 3 years and completed questionnaires measuring emotion regulation, meaning making, distress, and PTG. Emotion suppression positively predicted distress, but not PTG. Meaning making positively predicted PTG and negatively predicted distress. Bootstrapped mediation models showed that emotional processing has a significant indirect effect on PTG and distress through its effect on meaning making. Results indicate that researchers should pay closer attention to emotional processes involved in etiological models of PTG. It might also be helpful to examine specific emotion regulation strategies, as these can point to ways to help people navigate recovery from trauma.     

Adjustment to War Captivity: The Role of Sociodemographic Background,Trauma Severity,and Immediate Responses,in the Long-Term Mental Health of Israeli Ex-Pows

This study assessed the role of sociodemographic features, pre-captivity combat exposure, captivity severity, emotional responses and coping during captivity, and social support at homecoming, to the short- and long-term mental health of 164 Israeli POWs of the 1973 Yom Kippur War. The major contributors to the POWs' mental health were psychological responses during captivity, followed first by their education and ethnic status, and then by severity of captivity. Both traumatic stress of captivity and the results of the study were discussed in the light of Conservation of Resources (COR) theory.
