Type D personality and cardiac output in response to stress

Type D personality is predictive of adverse clinical outcome and psychological distress in cardiac patients. However, the mechanisms by which Type D affects health are largely unknown. This study (1) investigated the relationship between Type D and cardiovascular reactivity to experimentally induced stress and (2) tested the influence of Type D on subjective feelings of stress. Eighty four healthy young adults (50% males, mean (SD) age 22 (6.84) years), completed measures of Type D personality, stress arousal and a stress-inducing procedure involving a taxing mental arithmetic task. Cardiovascular measures were recorded throughout the experiment. Mixed measures ANOVA showed a significant main effect of Type D and a significant group by time effect of Type D on cardiac output in male participants. Type D males exhibit significantly higher cardiac output during the stressor phase compared to non-Type D males. However, there was no relationship between Type D and cardiovascular reactivity in females. In addition, Type D individuals exhibited significantly higher feelings of subjective stress compared to non-Type D's. These findings provide new evidence on Type D and suggest that Type D may affect health through increased cardiac output and higher subjective feelings of stress following acute stress.     

Evolutionary dynamics of Lewis signaling games: signaling systems vs. partial pooling

Transfer of information between senders and receivers, of one kind or another, is essential to all life. David Lewis introduced a game theoretic model of the simplest case, where one sender and one receiver have pure common interest. How hard or easy is it for evolution to achieve information transfer in Lewis signaling?. The answers involve surprising subtleties. We discuss some if these in terms of evolutionary dynamics in both finite and infinite populations, with and without mutation.     

The role of rumination,attentional biases and stress in psychological distress

This experimental study examines the relationship between rumination and attentional bias. Additionally, the study aims to determine, within a diathesis‐stress framework, whether rumination or attentional bias (or both) can prospectively predict psychological distress. Eighty‐one participants completed selected measures of rumination and psychological distress at time one, in addition to experimental manipulations of rumination and mood, and measures of mood and attentional bias at time two. Seventy‐three participants (90% follow‐up) completed final measures of stress and psychological distress approximately 3 weeks later. In combination with negative mood, inducing rumination decreased positive attentional bias, whilst inducing distraction increased positive attentional bias. Rumination and stress interacted to predict change in psychological distress. Negative attentional bias showed a trend towards interacting with rumination and stress to predict dysphoria. The findings supported the proposed diathesis‐stress models. In addition, a causal relationship between rumination and positive attentional bias has been empirically established for the first time.     

Empowering high‐risk clients to attain a better quality of life: a career resiliency framework

Career counselors frequently encounter clients who are at high risk for career and life development difficulties. Research suggests there is a connection between resiliency and successful career development in high‐risk clients. Many high‐risk individuals have poor decision‐making skills and lack motivation to succeed in life and career development. This article describes a career resiliency framework in which career resiliency is best understood within the context of psychological resiliency. Specifically, this article explicates how career counseling from a resiliency theory perspective may promote successful career development for populations dealing with multiple barriers.     

Perceived Discrimination Among Ethnic Minority Young People: The Role of Psychological Variables1

Because of difficulties in objectively determining discrimination, attention has turned to individual differences in perceptions of discrimination. This study aimed to build on such work by investigating the role of psychological variables in predicting perceived discrimination (PD) in a UK sample of ethnic minority young people (n= 154). A series of multiple regression analyses yielded 3 pathways leading to PD. There was a direct effect of gender on PD. Depression and low self‐esteem and need for approval predicted anxiety, which in turn was related to higher PD. Finally, private collective self‐esteem correlated with public collective self‐esteem, which in turn predicted lower PD. The results point to the importance of psychological variables, both personal and collective, in the perception of ethnic discrimination. Furthermore, the findings enhance our understanding of the complex associations between self‐esteem, affect, and PD.     

Mothers continuing bonds and ambivalence to personal mortality after the death of their child--an interpretative phenomenological analysis

The main objective of this study was to identify how bereaved mothers describe their coping strategies in their own words. The literature on parental bereavement is sparse, and the present study aims to add to existing knowledge by eliciting the mothers' experiences covering a wide range of child ages including infants, younger children and adults. Semi-structured interviews were held with 13 bereaved mothers in the UK. Causes of death include accident, illness and suicide. The methodological approach was interpretative phenomenological analysis (IPA). This article reports two inter-related recurrent themes: (1) Continuing the bond with the deceased child and (2) Ambivalence to personal mortality. Participants reported that the relationship with their child was continued in a variety of ways, from tending to the grave and the child's remains, through linking objects or by establishing a symbolic representation of the child within their daily lives. All mothers talked openly about their own mortality, either demonstrating ambivalence about their own death, or expressing clear suicidal ideation. Death was seen as a release from living with the pain of loss. The presence of surviving siblings appeared to moderate suicidal ideation, but mothers expressed concerns about their ability to care adequately for other family members during times of intense grief.     

Attitudes and Knowledge of Maternal-Fetal Medicine Fellows Regarding Noninvasive Prenatal Testing

Using cell-free DNA in maternal serum to detect fetal aneuploidy has been shown to have high sensitivity and specificity. The purpose of this study was to assess attitudes and knowledge of Maternal-Fetal Medicine (MFM) fellows regarding noninvasive prenatal testing (NIPT). A 13 question survey was sent via listserv to US-based MFM fellows. One hundred sixteen fellows responded, a 42.3 % response rate, with >75 % reporting they are comfortable ordering NIPT. Most (82 %) preferred that a patient discuss options with a provider or genetic counselor. Three common methods used to learn about NIPT were: formal educational activities (n?=?78, 69 %), self-review of the literature (n?=?76, 67 %), and discussions with peers (n?=?73, 65 %). On questions related to trisomy 21, accuracy was >70 %. However, accuracy was lower regarding use in twin pregnancies (42 %) and monosomy X screening (50 %).
