Associations of transcranial doppler velocity,age, and gender with cognitive function in children with sickle cell anemia in Nigeria

Children with sickle cell anemia (SCA) have elevated cerebral blood velocity relative to healthy peers. The primary aim of this study was to evaluate the association between cerebral blood velocity, measured by transcranial Doppler (TCD) ultrasound, age, and gender with cognitive function in children with SCA in Nigeria. Eighty-three children (M_age = 9.10, SD = 1.90 years; 55% female) with SCA in Nigeria completed cognitive assessments and a TCD ultrasound. The association between TCD velocity and measures of perceptual reasoning (Raven’s Progressive Matrices), working memory (WISC-IV Digit Span), and executive planning (Tower of London, TOL) were assessed. Results showed that elevated TCD velocity significantly predicted lower scores on TOL Time Violations and Total Problem-Solving Time when controlling for BMI, hemoglobin level, and parent education, suggesting that TCD velocity is related to the efficiency of executive function. Further, age was negatively related to children’s performance on the Ravens Matrices and TOL Total Correct, and boys showed greater deficits on the TOL Total Correct relative to girls. Moderation analyses for gender showed that there was a conditional negative association between TCD velocity and Digit Span for boys, but not for girls. Findings suggest that children with SCA in Nigeria with elevated TCD velocity are at risk for deficits in efficiency of executive planning, and boys with elevated TCD velocity are particularly at increased risk for deficits in auditory working memory. Implications of this study are important for interventions to reduce cerebral blood velocity and the use of TCD in this population.     

Resting Frontal EEG Asymmetry and Personality Traits: A Meta‐analysis

Frontal asymmetry has been widely used as a marker of emotion, motivation, and psychopathology. When assessed during the resting state, it is regarded as an index of trait approach and withdrawal motivation. However, the replicability of these associations with personality is currently unclear. The present meta‐analysis seeks to provide a comprehensive quantitative review of the relationship between personality traits and resting electroencephalographic (EEG) frontal asymmetry. We distinguished five personality clusters: extraversion, neuroticism, impulsivity, anger, and defensiveness. Data from 79 independent samples with overall 5700 participants were included in the meta‐analysis. The results revealed that less than 0.4% of the variance in extraversion and neuroticism could be explained by resting frontal asymmetry. Similarly, a small effect was observed for trait anger, and a small‐sized to medium‐sized effect was observed for defensiveness, although the number of studies was very low. No significant effect emerged for impulsivity. The effects were further reduced after adjustment for publication bias. Given some evidence for heterogeneity, sub‐traits were analysed, and methodological moderators were investigated. Based on the results, we conclude that the validity of resting frontal asymmetry as a marker for personality is not supported. Finally, recommendations are given to increase the replicability of frontal asymmetry research. © 2019 European Association of Personality Psychology     

The interplay between relationship effectiveness,life stress,and sleep: A prospective study

Research has shown that greater stress responses predict worse sleep and that the quality of one's current romantic relationship predicts one's sleep. Despite these established links, research has not examined connections between ongoing patterns of interpersonal experiences and competencies (relationship effectiveness) and stress exposure on sleep. Participants in the Minnesota Longitudinal Study of Risk and Adaptation (MLSRA) completed measures assessing relationship effectiveness and stress exposure at ages 23 and 32 years, as well as sleep quality/duration at age 37 years. Analyses demonstrate that relationship effectiveness at age 23 years positively predicts sleep quality—but not sleep duration—at age 37 years via reduced stress exposure at age 32 years. These findings highlight the effects of relationship effectiveness and stress exposure across early to middle adulthood on sleep.

Identity Status Change Within Personal Style Clusters: A Longitudinal Perspective From Early Adulthood to Midlife

Differences in identity stability and change from age 36 through 42 to 50 were examined between three male and female personal style clusters extracted at age 27. We expected, first, the identity statuses to consistently differ between the clusters and, second, those with the least mature identity to move closer to others during midlife. Differences between the personal style clusters were discovered on all identity statuses across ages. Although significant personal style × age interactions were not detected, some evidence of pace-of-development differences emerged for women: Initial differences in identity maturation between the female groups partially leveled off by midlife. In men, early adulthood identity maturation in the conflicted group was however followed by a re-decline in later midlife.     

Positive and negative mood following imaging-guided core needle breast biopsy and receipt of biopsy results

Positive and negative mood are independent psychological responses to stressful events. Negative mood negatively impacts well-being and co-occurring positive mood leads to improved adjustment. Women undergoing core needle breast biopsies (CNB) experience distress during CNB and awaiting results; however, influences of mood are not well known. This longitudinal study examines psychosocial and biopsy- and spirituality-related factors associated with mood in patients day of CNB and one week after receiving results. Ninety women undergoing CNB completed questionnaires on psychosocial factors (chronic stress, social support), biopsy experiences (pain, radiologist communication), and spirituality (peace, meaning, faith) day of CNB. Measures of positive and negative mood were completed day of CNB and one week after receiving results (benign n = 50; abnormal n = 25). Multiple linear regression analyses were conducted. Greater positive mood correlated with greater peace (β = .25, p = .02) day of CNB. Lower negative mood correlated with greater peace (β = ?.29, p = .004) and there was a trend for a relationship with less pain during CNB (β = .19, p = .07). For patients with benign results, day of CNB positive mood predicted positive mood post-results (β = .31, p = .03) and only chronic stress predicted negative mood (β = .33, p = .03). For women with abnormal results, greater meaning day of CNB predicted lower negative mood post-results (β = ?.45, p = .03). Meaning and peace may be important for women undergoing CNB and receiving abnormal results.     

Antecedents of daily team job crafting

This study investigated potential antecedents of team job crafting defined as the extent to which team members engage together in increasing (social and structural) job resources and challenges, and decreasing hindering job demands. Mindful of the teamwork literature, we hypothesized that individual employee factors (self-efficacy for teamwork, daily affect), team features (team cohesion, climate) and the organizational context of teams (engaging leadership and organizational resources for teamwork) relate positively to daily team job crafting behaviour. Data were collected among 46 multi-professional rehabilitation teams whose members completed two daily surveys after their weekly meetings. Multilevel regression analyses showed that self-efficacy for teamwork and team members’ positive affect were positively associated with team job crafting behaviour at the individual (within-team) level. In addition, a team climate characterized by a clear vision of the teams’ targets, supportiveness and innovation and connecting leadership were positively related to daily team job crafting at both the within- and between-team levels of the data. Overall, the study offers novel insights into the antecedents of teams’ daily job crafting behaviours. For practice, the results suggest that actions and interventions conducive to positive team processes offer the most promising route to enhancing team job crafting behaviour.     

Men’s experience of a guided self-help intervention for hot flushes associated with prostate cancer treatment

Up to 80% of men who receive androgen deprivation therapy report hot flushes and for many these are associated with reduced quality of life. However it is recognised that there are a number of barriers to men’s engagement with support to manage symptoms and improve quality of life. This qualitative study was embedded within a larger randomised controlled trial (MANCAN) of a guided self-help cognitive behavioural intervention to manage hot flushes resulting among men receiving androgen deprivation therapy. The study aimed to explore the engagement and experiences with the guided self-help intervention. Twenty men recruited from the treatment arm of the MANCAN trial participated in a semi-structured interview exploring acceptability of the intervention, factors affecting engagement and perceived usefulness of the intervention. Interviews were audio-recorded, transcribed verbatim and analysed using a Framework approach. Over two thirds of respondents (69%) reported reading the intervention booklet in full and over 90% reporting practising the relaxation CD at least once a week. Analysis of the interviews identified three super-ordinate themes and these related to changes in hot flush symptomatology (learned to cope with hot flushes in new ways), the skills that participants had derived from the intervention (promoting relaxation and reducing stressors), and to a broader usefulness of the intervention (broader impact of the intervention and skills). The present study identified positive engagement with a guided self-help intervention and that men applied the skills developed through the intervention to help them undertake general lifestyle changes. Psycho-educational interventions (e.g. cognitive behaviour therapy, relaxation, and positive lifestyle elements) offer the potential to be both effective and well received by male cancer survivors.

Cumulative Risk,Emotion Dysregulation,and Adjustment in South African Youth

Research on cumulative risk is growing, however, little work has occurred in low- or middle-income countries, and few studies have focused on processes linking risk to outcomes. This study explored relations between components of cumulative risk and adjustment in a sample of 324 South African youth (M age?=?13.11 years; SD?=?1.54 years; 65% female; 56% Black/African; 14% Colored; 23% Indian; 7% White), and tested competing models of emotion dysregulation as a mediator or moderator of risk—adjustment links. Data was collected from youth and their female caregivers during home interviews. Structural equation models and regression analyses accounting for age and sex contributions revealed that emotion dysregulation mediated associations between sociodemographic risk and internalizing symptoms, externalizing problem behavior, and drug use severity, and moderated links between psychosocial risk and internalizing symptoms and externalizing problem behavior. For the mediator models, sociodemographic risk was associated with impaired emotion regulation, which in turn was linked with heightened adjustment difficulties. For the moderator models, psychosocial risk was linked with adjustment problems only when emotion dysregulation was high. These data indicate the importance of disentangling components of cumulative risk. Future research within the South African cultural context might build on these findings by adapting and testing school- or family-based prevention or intervention programs that include modules on emotion regulation.
