Repeated acute stress alters heart morphometry in male and female rats differently

Stress exerts deleterious effects on the cardiovascular system. Left ventricular hypertrophy has been identified as a risk factor for heart disease. The effects of stress on other heart parameters, including heart size and heart shape, are not well-characterized. In addition, the extent to which males and females differ in stress effects on these measures has not been examined, but may help to further explain gender differences in heart disease morbidity and mortality. The present experiment examined effects of mild daily stress on heart morphology and blood volume (obtained by ex-sanguination at decapitation) in 39 male and 40 female rats of two strains. Following 14 days of stress exposure, rats were killed and blood volume was measured. Heart length, heart weight, left ventricle cavity width, right ventricle width, lateral wall thickness, anterior wall thickness, posterior wall thickness, and septal wall thickness were measured. In males, after controlling for body weight, stress decreased heart length and left ventricle cavity width and increased septal wall thickness. In females, after controlling for body weight, stress reduced total blood volume, but did not significantly affect other heart parameters. These findings suggest that stress exposure can alter heart morphology and blood volume and that there are sex differences in these effects.     

Perceived social support, self-efficacy, and adjustment to abortion

Prior to their having a 1st trimester abortion, women's perceptions of social support from their partner, family, and friends and self-efficacy for coping were assessed. Depression, mood, physical complaints, and anticipation of negative consequences were measured after the 30-min recovery period. As predicted, perceived social support enhanced adjustment indirectly through its effects on self-efficacy. Women who perceived high support from their family, friends, and partners had higher self-efficacy for coping. Higher self-efficacy, in turn, predicted better adjustment on the psychological measures but not on the physical complaint measure. No direct path between social support and adjustment was observed. In addition, women who told close others of their abortion but perceived them as less than completely supportive had poorer postabortion psychological adjustment than either women who did not tell or women who told and perceived complete support.     

Self-blame, self-efficacy, and adjustment to abortion

The causal impact of attributions and coping self-efficacy on adjustment to abortion was examined. Two hundred and eighty-three women were randomly assigned prior to their abortion to 1 of 3 counseling interventions: 1 designed to alter attributions for unwanted pregnancy (ATT-INT), 1 designed to raise coping expectations (EXP-INT), or a control (standard counseling) group. Depression, mood, anticipated consequences, and physical complaints were assessed postabortion. Women in the ATT-INT or EXP-INT group were better adjusted immediately postabortion than women in the control group. The EXP-INT group was also less depressed than the ATT-INT group. Three individual difference factors were also related to better adjustment: high coping self-efficacy, low self-character blame, and low other-blame. Self-efficacy also predicted adjustment 3 weeks postabortion. Implications for theories of adjustment to major life events, therapeutic interventions to assist coping with such events, and public policy on abortion are discussed.     

The support gap for dual clergy couples

Within this study six levels of support for dual clergy couples with and without children were investigated. Seven dual clergy couples of several synods of the Lutheran Church in two western Canadian provinces were asked open-ended questions about the support they had received in several employment and family related areas. While findings in each of the areas varied, overall, most individuals received the most support from their spouse and little from close friends and relatives often due to physical distance. Support provided by other clergy and church administrators was mixed. Only one major difference was found between couples with and without children. The group without children were more optimistic about the support that would be provided by family and friends in the area of child care while couples with children failed to mention support from friends and family.     

Office or kitchen? Wellbeing consequences of role participation depend on role salience

In light of the emerging trend of men and women sharing work and family roles, the goal of this study is to investigate which individuals will experience a role as depleting or enriching their energy levels. We apply self-discrepancy theory and propose that role salience explains when a role will lead to exhaustion versus engagement. Exhaustion is likely when participating in a role for which salience is low, while engagement is likely when spending time on a role for which salience is high. We test this idea using a diary study whereby participants logged time spent on work and family tasks on seven consecutive days, while reporting feelings of exhaustion and engagement in the morning. For individuals with high work salience, time spent on work increased exhaustion less, and increased engagement more, as compared to individuals with low work salience. Spending time on family tasks increased exhaustion less, and increased engagement more, when work role salience was low as compared to high. Our findings suggest that wellbeing consequences of role participation depend on work role salience. We discuss how these findings advance theoretical thinking in the work–family literature and give leads for managerial practice.     

The power of affirming group values: Group affirmation buffers the self-esteem of women exposed to blatant sexism

Extending the group affirmation literature to the domain of prejudice, this study investigated whether group affirmation buffers the self-esteem of women exposed to blatant sexism. In accordance with Self-Affirmation Theory and group affirmation research, we hypothesized that when one aspect of the collective self is threatened (gender identity), self-esteem can be maintained via the affirmation of an alternative aspect of the collective self. In a 2 × 2 between-participants design, female students were randomly assigned to read about discrimination directed toward women or a non-self-relevant disadvantaged group (the Inuit). All then participated in a (fictitious) second study, in which half completed a group affirmation manipulation (wrote about the top three values of a self-defining group) and half completed a control writing exercise. The self-esteem of women who were threatened by sexism, but group affirmed, was protected from the negative effects of perceiving sexism.     

Enhancing social relationships through positive psychology activities: a randomised controlled trial

Despite the robust relationship between well-being and social relationships, the latter has received little examination within positive psychology activities (PPAs). This study aimed to test whether kindness- and gratitude-based PPAs, through positive social interaction with peers, enhanced relationship satisfaction. Using a longitudinal randomised controlled design, 225 participants were assigned to one of three conditions (relationship-focused, self-focused or control) and completed measures of relationship satisfaction, social support and happiness on three occasions (baseline, post-intervention and six weeks). The experimental PPAs were relationship-focused (involving social interaction) or self-focused (no social interaction). Those who completed relationship-focused PPAs had greater increases in relationship satisfaction than the self-focused and active control activities at six-week follow-up. Additionally, only those in the relationship-focused condition felt their existing friendships had improved at intervention cessation. Regardless of participants’ initial levels of social support, the intervention effects remained. In conclusion, PPAs fostering social kindness and gratitude significantly strengthened relationship satisfaction.     

Scripts and checkerboards: The influence of ordered visual information on remembering locations in infancy

Five-month-old infants were trained to fixate 4 event locations, and memory for sequential locations was assessed following training. Results of two studies reveal that ordered visual information influences young infants' memory for sequential events.
