Aggressive Children and Effective Communication

Testing a component of a theoretical model which postulates that low levels of communication effectiveness accompany the social and affective problems presented by aggressive children, the study compared the communication skills of a group of aggressive (n = 49) and nonaggressive (n = 49) elementary school children (selected on the basis of teacher ratings) in a structured and cooperative communication task. Based on direct observational measures of communication effectiveness and aggression, and on teacher, peer, and self-rating measures of peer rejection and depressive symptoms, results showed that (a) aggressive children exhibited less effective communication skills and more disruptive communication skills than nonaggressive peers; (b) aggressive children experienced higher levels of peer rejection and depressive symptoms than nonaggressive peers; and (c) group differences in communication effectiveness could not be accounted for by differences in observed aggression and remained significant, even after controlling for differences in peer status and affective functioning. These findings highlight the role that ineffective communication may play in the development and maintenance of aggression and have important theoretical and applied implications, which are briefly discussed. © 1994 Wiley-Liss, Inc.     

Parents’ postnatal depressive symptoms and their children's academic attainment at 16 years: Pathways of risk transmission

The aim of the study was to examine whether parents’ increased postnatal depressive symptoms predicted children's academic attainment over time and whether the parent–child relationship, children's prior academic attainment, and mental health mediated this association. We conducted secondary analyses on the Avon Longitudinal Study of Parents and Children data (12,607 mothers, 9,456 fathers). Each parent completed the Edinburgh-Postnatal Depression Scale at 8 weeks after the child's birth (predictor) and a questionnaire about the mother–child and father–child relationship at 7 years and 1 month (mediator). The children's mental health problems were assessed with the teacher version of the Strengths and Difficulties Questionnaire at 10–11 years (mediator). We used data on the children's academic attainment on UK Key Stage 1 (5–7 years; mediator) and Key Stage 4 (General Certificate of Secondary Education 16 years) (outcome). We adjusted for the parents’ education, and child gender and cognitive ability. The results revealed that parents’ depressive symptoms at 8 weeks predicted lower academic performance in children at 16 years. Mothers’ postnatal depressive symptoms had an indirect effect through children's mental health problems on academic outcomes at 16 years via negative mother–child relationship, and prior academic attainment. There was a significant negative indirect effect of fathers’ postnatal depressive symptoms on academic attainment at 16 years via negative father–child relationship on child mental health. The findings suggest that the family environment (parental mental health and parent–child relationship) and children's mental health should be potential targets for support programmes for children of depressed parents.     

Hungry people prefer larger bodies and objects: The importance of testing boundary effects

Several lab-based studies have indicated that when people are hungry, they judge larger women's bodies as more attractive, compared to when they are satiated. These satiety-dependent judgements are assumed to provide explanatory power when it comes to the noted cross-cultural differences in attitudes towards women's adiposity, whereby people who live in regions that are under greater nutritional stress tend to have more favourable attitudes towards bigger bodies. However, it is premature to assume that women's bodies are the proper or actual domain of the satiety-dependent judgement shifts found within research study testing contexts until stimuli other than female bodies have also been tested: The research programme falls into the trap of confirmation bias unless we also seek out disconfirmatory evidence and test the boundaries of the effects of hunger. Accordingly, we collected attractiveness judgements of female and male bodies manipulated to vary in size by varying level of adiposity, and objects manipulated to vary in size, from 186 participants who also reported their current hunger level. We found that larger sizes of stimuli in general, and women's bodies in particular, especially when judged by women, were judged as more attractive by the hungrier participants. We discuss these patterns in the context of the Insurance Hypothesis, the Environmental Security Hypothesis, and the impact of hunger on acquisition.     

Paths from core belief disruption to post-traumatic stress symptoms and post-traumatic growth among Korean undergraduates: The mediating role of rumination

The post-traumatic growth (PTG) model proposes that cognitive processing is a key mechanism that leads to growth in the aftermath of traumatic events. Building upon the PTG model, the present study examined the paths from the disruption of core beliefs to post-traumatic stress symptoms (PTSS) and PTG via intrusive and deliberate rumination. The sample includes 370 Korean undergraduate students who reported at least one highly stressful experience in their lifetime. Structural equation modeling demonstrated that disruption of core beliefs predicted PTG both directly and indirectly through multiple pathways: via deliberate rumination, intrusive rumination, and the path from intrusive to deliberate rumination. The disruption of core beliefs positively predicted PTSS only through intrusive rumination. No bivariate relationship was found between PTSS and PTG. These findings support the different roles of intrusive rumination and deliberate rumination in mediating the paths from disruption of core beliefs to PTSS and PTG. Implications and limitations of this study were discussed.     

Regression II. Development through regression

As shown in our previous paper (‘Regression I. Experimental approaches to regression’, JAP, 65, 2, 345-65), the common mechanism of regression can be described as reversible dedifferentiation, which is understood as a relative increase of the proportion of low-differentiated (older) systems in actualized experience. Experimental data show that regression following disease (chronic tension headache) is followed by adaptation and an increase in system differentiation in that experience domain which contains systems responsible for that adaptation. The results of mathematical modelling support the idea that reversible dedifferentiation can be one of the mechanisms for increasing the effectiveness of adaptation through learning. Reversible dedifferentiation, which is phenomenologically described as regression, is a general mechanism for restructuring the organism-environment interactions in situations where behaviours that were effective in the past become ineffective. Reversible dedifferentiation has evolved as a component of adaptation when new behaviours are formed and large-scale modifications in the existing behaviours are required in the face of changes in the external and/or internal environment. Thus, the authors believe that this article provides evidence for Jung’s view that regression is not only a ‘return’ to past forms of thinking, affects and behaviour, but that regressive processes provide a significant impetus for psychological growth and development.     

Triggering Creative Self-Efficacy to Increase Employee Innovation Behavior in the Hospitality Workplace

This study investigated how creative personality, psychological empowerment, and job stress affect creative self-efficacy and innovative behavior in hospitality employees. A hypothesized moderating role of knowledge-sharing role in the relationship between creative self-efficacy and innovative behavior was also tested. Three hundred and thirty-nine employees and 89 supervisors employed by International Tourist Hotels in Taiwan participated in the study. A structural equation modeling analysis indicated that creative self-efficacy significantly mediates the effects of creative personality and psychological empowerment on innovative behavior in the hospitality industry. The positive effect of creative self-efficacy on innovative behavior was larger in high knowledge-sharing work environments than in low knowledge-sharing work environments. Theoretical and practical implications are further discussed.     

A Two-way Street: Mentor Stress and Depression Influence Relational Satisfaction and Attachment in Youth Mentoring Relationships

Over the past two decades, youth mentoring programs have increased in popularity as an intervention for children exposed to a range of stressful life circumstances. Such programs have been shown to promote positive youth development and reduce risk for emotional and behavioral problems; yet, the effect size of youth gains remains small. The current study examined the influence of college student mentors’ history of early life stress and baseline depressive symptoms on their effectiveness in youth mentoring relationships using 340 randomized mentor–youth pairs from College Mentors for Kids, a well-established mentoring program with chapters across the United States. Hierarchical linear models revealed that mentors with higher levels of depressive symptoms reported lower relationship satisfaction and increased avoidance in the mentoring relationship. In contrast, mentors who experienced higher levels of early life stress had youth who reported greater satisfaction in the mentoring relationship and decreased relational anxiety. These findings are some of the first to examine the impact of mentor characteristics on mentor–youth relationships and highlight the importance of considering factors relevant to psychosocial functioning and emotional distress when recruiting, training, and supporting college student mentors.     

Antecedents of fathers’ perception of child behavior at child age 12 months

This study investigates whether fathers’ adverse childhood experiences (ACE) and attachment style reported during pregnancy predict fathers’ perception of child behavior assessed 12 months postpartum, expressed by the Parenting Stress Index (PSI), Child Domain. Prospective fathers (N = 835) were recruited to “The Little in Norway (LiN) study” (Moe & Smith) at nine well-baby clinics in Norway, with data collection composed of five time points during pregnancy and two time points postpartum (6 and 12 months). The main analyses included linear regression, path-analysis modeling, and intraclass correlation based on mixed effects modeling. First, linear regression analyses showed that neither fathers’ ACE nor attachment style significantly predicted perceived child behavior postpartum directly. Furthermore, path analyses showed that ACE and less secure attachment style (especially avoidant attachment) measured early in pregnancy strongly predicted negatively perceived child behavior, mediated by fathers’ mental health symptoms during pregnancy and partner disharmony postpartum. Second, intraclass correlation analyses showed that fathers’ perceived child behavior showed substantial stability between 6 and 12 months postpartum. Family interventions beginning in pregnancy may be most beneficial given that fathers’ early experiences and perceptions of attachment in pregnancy were associated with later partner disharmony and stress.     

急性应激损伤错误监控与错误后调整

生活中, 个体会时时关注自己的行为结果并及时做出调整以适应环境的变化。但在应激下个体能否有效地监控行为并做出适应性调整依然未知。本研究招募了52名男性大学生被试, 将其随机分入应激组与控制组, 采用特里尔社会应激测试(Trier Social Stress Test, TSST)诱发个体的应激反应, 并结合错误意识任务(Error Awareness Task, EAT)探索个体急性应激下的错误监控与错误后调整过程。应激指标的结果显示应激组个体在应激任务后唾液皮质醇、心率、应激感知自我报告和负性情绪均显著高于控制组, 表明急性应激的诱发是成功的。行为结果显示应激组的错误意识正确率显著低于控制组, 错误意识反应时显著短于控制组; 进一步地, 应激组个体在意识到错误之后的试次上正确率显著低于未意识到错误之后的试次, 并且应激组个体在意识到错误之后的试次上正确率低于控制组。结果表明急性应激降低了个体对错误反应的监控水平, 即便在辨别出错误反应的情况下, 个体的行为监控与调节也更差。本研究说明急性应激会损伤行为监控系统, 导致个体的行为适应性下降。     

Hair sampling for cortisol analysis with mother-toddler dyads living in low-income homes

BackgroundA first step to advance stress science research in young children is understanding the relationship between chronic stress in a mother and chronic stress in her child. One non-invasive measure of chronic stress is hair cortisol. However, little is known about strategies for hair sampling in mother-toddler dyads living in low-income homes in the U.S. To address prior limitations, the purpose of this study was to understand the feasibility of sampling hair for cortisol analysis in mother-toddler dyads living in low-income homes in the U.S. We examined feasibility related to participation, eligibility, and gathering an adequate hair sample weight.MethodsWe approached 142 low-income, racially diverse, urban-dwelling mothers who were participating in an ongoing longitudinal birth cohort study for informed consent to cut approximately 150 hairs from the posterior vertex of their scalp and their toddlers’ (20–24 months) scalp. We demonstrated the process of sampling hair with a hairstyling doll during home visits to the mother and toddler using rounded-end thinning shears.ResultsOverall, 94 of 142 mother-toddler dyads (66 %) participated in hair sampling. The most common reason for participation refusal was related to hairstyle. All but three hair samples were of adequate weight for cortisol extraction.DiscussionThe findings from this study can help researchers address sampling feasibility concerns in hair for cortisol analysis research in mother-toddler dyads living in low-income homes in the U.S.
