Can self-affirmation exacerbate adverse reactions to stress under certain conditions?

Objective: Self-affirmation has repeatedly been shown to reduce adverse psychological and physiological responses to stress. However, it is plausible that self-affirmation could exacerbate negative reactions to stress under certain conditions. The current research explored whether self-affirmation would increase negative psychological responses to a stressor occurring in a central life domain characterised by low levels of control.

Design: Female participants (Study 1 N = 132; Study 2 N = 141) completed baseline measures of anxiety and mood. They were then randomly allocated to complete a self-affirmation or control task, before reading a narrative documenting a stressful birth and imagining themselves in the place of the woman giving birth. After completing this task, participants again reported their levels of anxiety and positive mood.

Main outcome measures: Anxiety and positive mood assessed at follow-up.

Results: Study 1 demonstrated that self-affirmed women experienced increased anxiety and less positive mood at follow-up, compared both to baseline and to women in the control condition. Study 2 revealed that the effect of self-affirmation on outcomes was moderated by fear of childbirth.

Conclusion: These results provide preliminary evidence that self-affirmation may worsen negative responses to stressors under certain conditions and for certain individuals.     

Characteristics of memories for traumatic and nontraumatic birth

Evidence for memory characteristic differences between trauma and other memories in non‐clinical samples is inconsistent. However, trauma is frequently confounded with the event recalled. This study compares trauma and nontrauma memories for the same event, childbirth, in a non‐clinical sample of 285 women 4–6 weeks after birth. None of the women met diagnostic criteria for post‐traumatic stress disorder. Traumatic birth, defined by the DSM‐5 event criterion, was reported by 100 women. The ratings of some memory characteristics did not differ between memories for traumatic and nontraumatic birth: All were rated highly coherent and central to women's lives, with moderate sensory memory. However, women who experienced traumatic births reported more involuntary recall, reliving, and negative/mixed emotions. Thus, trauma memories differed from nontrauma memories. In this non‐clinical sample, this is likely to be due to encoding during trauma rather than the distinctive memory profile for memories retrieved by those experiencing trauma symptoms.     

Preschoolers' emotion knowledge: self-regulatory foundations, and predictions of early school success

Preschoolers (N=322 in preschool, 100 in kindergarten) were assessed longitudinally to examine the self-regulatory roots of emotion knowledge (labelling and situation) and the contributions of emotion knowledge to early school adjustment (i.e., including social, motivational, and behavioural indices), as well as moderation by age, gender, and risk. Age, gender, and risk differences in emotion knowledge were also examined. Emotion knowledge skills were found to be more advanced in older children and those not at economic risk, and in those with higher levels of self-regulation. Overall, the results support the role of emotion knowledge in early school adjustment and academic success even with gender, age, and risk covaried, especially for boys, older preschoolers, and those at economic risk.     

“It Depends on What You Mean by ‘Disagree’”: Differences between Parent and Child Perceptions of Parent–Child Conflict

We examined a new structured interview of parent?Cchild conflict that assesses parent and child perceptions of behavioral conflict about daily life topics (e.g., doing chores, homework), and whether discrepancies exist on beliefs about these topics. In a sample of 100 parents and children ages 10 to 17?years (M?=?13.5?years, 52 males, 57?% African-American), informants could reliably distinguish between perceived behavioral conflicts and perceived discrepant beliefs about topics. These scores were also significantly related to questionnaire reports of parent?Cchild conflict. Parent and child questionnaire reports did not significantly differ, yet on the structured interview, parents reported significantly greater levels of perceived conflict and discrepant beliefs relative to child reports. Additionally, structured interview reports of conflict demonstrated incremental validity by relating to child self-reports of delinquent behaviors, when accounting for questionnaire conflict reports. The findings have implications for increasing understanding of the links between parent?Cchild conflict and psychosocial outcomes.     

What makes labour and birth traumatic? A survey of intrapartum 'hotspots'

Evidence suggests between 1% and 6% of women develop post-traumatic stress disorder (PTSD) after childbirth. 'Hotspots' are moments of extreme distress during traumatising events that are implicated in symptoms of PTSD. This cross-sectional internet survey of hotspots examined (1) the content of intrapartum hotspots and (2) whether particular events, cognitions or emotions during hotspots are related to PTSD. Women (N?=?675) who experienced a difficult or traumatic birth completed a questionnaire composed of a validated measure of PTSD, questions concerning the existence of hotspots, and a newly developed measure of emotions and cognitions during hotspots. The majority of women (67.4%) reported at least one hotspot during birth and 52.9% had re-experiencing symptoms of these hotspots. Women were more likely to have PTSD if hotspots involved fear and lack of control (odds ratio (OR) 1.30, 95% CI 1.17-1.43) or intrapartum dissociation (OR 1.12, 95% CI 1.05-1.19). Risk of PTSD was higher if hotspots concerned interpersonal difficulties (OR 4.34, 95% CI 2.15-8.77) or obstetric complications (OR 3.35, 95% CI 1.64-6.87) compared to complications with the baby.     

What do pre-adolescents and adolescents understand about HIV/AIDS?

Abstract

Pre-adolescents and adolescents (N= 80, aged 10, 12, 15, and 18 years) were tested on their knowledge of HIV/AIDS. Knowledge was assessed using a self-report questionnaire (examining levels of factual knowledge) and a semi-structured interview (examining cognitive developmental levels of understanding). Examination of the developmental shifts in understanding of HIV/AIDS revealed an increase in conceptual complexity on causal and prevention dimensions. The main conceptual changes included a shift from single cause to multiple cause solutions and a shift from identifying surface or immediate features to implicating less salient features. Additionally, with age, concepts about HIV/AIDS were increasingly organised around internal, physiological principles. Questionnaire responses yielded significant age-related increases in knowledge. Level of knowledge, as measured by the questionnaire, was higher than that assessed by the interview for the three youngest age groups. Thus, factual information acquired about HIV/AIDS is not automatically accompanied by understanding. In light of these findings the past conclusion that adolescents have high levels of knowledge of HIV/AIDS is questioned.     

Support during birth interacts with prior trauma and birth intervention to predict postnatal post-traumatic stress symptoms

Background: Many women experience childbirth as traumatic and 2% develop post-traumatic stress disorder. This study examined the role of health practitioner support and personal control during birth as predictors of post-traumatic stress (PTS) symptoms, adjusting for vulnerability factors of prior trauma, depression, control beliefs and birth intervention. It also investigated interactions between support, prior trauma and birth intervention and their association with PTS symptoms.

Methods: A prospective longitudinal survey of 138 women recruited from UK NHS maternity clinics. Measures were taken in pregnancy, 3 weeks and 3 months after the birth.

Results: Support and control during birth were not predictive of postnatal PTS symptoms. However, support was predictive of PTS symptoms in a subset of women with prior trauma (β?=??0.41, R ²?=?16%) at both 3-weeks and 3-months postpartum. The interaction of birth intervention and support was associated with PTS symptoms 3 months after birth, the relationship between support and PTS symptoms was stronger in women experiencing more intervention.

Conclusions: Low support from health practitioners is predictive of postnatal PTS symptoms in women who have a history of trauma. Longer term effects of low support on postnatal PTS symptoms are also found in women who had more intervention during birth.     

Friendship Similarity During Early Adolescence: Gender and Racial Patterns

We studied the relationship of reciprocity, gender, and racial composition (Caucasian, African American, cross-race) of adolescent friendship dyads to similarity and proximity in 136 young adolescents. We found that adolescents selected friends who were of the same gender and race and that female dyads were more similar than male dyads on verbal achievement and several personality dimensions. Caucasian dyads were more similar than African American dyads on verbal achievement, mental alertness, and dominance. African American adolescents had more contact with their best friends outside school, whereas Caucasian adolescent friends had more in-school contact. African American students had fewer reciprocal relationships than the Caucasian students. Cross-race friendships were less reciprocal than same-race friendships. Race and gender were important in determining friendship patterns. Similarity and proximity were more important than reciprocity in understanding early adolescent friendships.     

Why do individuals respond to fraudulent scam communications and lose money? The psychological determinants of scam compliance

Why do so many people all over the world, so often, react to completely worthless scam offers? In two questionnaire studies, one of which included the distribution of an experimentally manipulated simulated scam, we investigated differences between respondents who did and did not report past compliance with scams. We found that the principal differences were in their response to very high‐value incentives, in the extent to which they reacted with positive emotions to the thought of winning a large prize, in their reliance on signs of official authority, and in their self‐confidence. The first two of these can be regarded as forms of visceral processing. Some of these differences suggested a dispositional difference between victims and non‐victims.     

Rumination and Impaired Cortisol Recovery Following a Social Stressor in Adolescent Depression

Response styles theory promotes rumination as a central cognitive construct driving negative mood and depression, and past research suggests that at least part of the mechanism driving rumination’s depressogenic effect is through inhibiting the individual’s ability to shift attentional focus away from negative environmental stimuli. In the current study, we hypothesized that high trait rumination would be associated with impaired recovery of the body’s biological response to psychological stress. In a community sample of depressed (n?=?31) and non-depressed (n?=?33) adolescents we assessed rumination and the more adaptive trait of distraction and problem-solving with the Children’s Response Styles Questionnaire (CRSQ; Abela 2000), and diagnostic status was confirmed using the Child and Adolescent Schedule of Affective Disorders and Schizophrenia (K-SADS; Kaufman et al. Journal of the American Academy of Child and Adolescent Psychiatry 36:980–988, 1997). Participants completed the Trier Social Stress Test (TSST; Kirschbaum et al. Neuropsychobiology 28:76–81, 1993), and the focus of our analyses was the change in salivary cortisol concentration between peak cortisol output (25 min post-stressor) and a sample taken during the “Recovery” period 65 minutes post-stressor. Consistent with the predictions of response style theory, among the depressed adolescents only, high trait rumination was associated with delayed post-stressor cortisol recovery, whereas high trait distraction and problem-solving was associated with more rapid recovery. In contrast, response styles were not associated with cortisol recovery in the non-depressed group. These findings implicate impaired post-stress cortisol recovery as a potential mechanism underlying the pathological effect of rumination on the development and maintenance of Major Depressive Disorder (MDD).
