Maternal Trauma and Children’s Functioning: The Role of Kinship Social Support

Although research has documented the detrimental effects of maternal trauma on child behavior (Lambert, Holzer, & Hasbun, 2014), the role of extended family support in potentially mitigating the effects of intergenerational transmission of trauma is not clearly understood. With a diverse community sample of 52 trauma-exposed mothers and their children between the ages of 7 and 12, we investigated relationships between kinship social support, maternal trauma exposure severity, maternal posttraumatic stress disorder (PTSD) symptom severity, and child behavioral problems. Results showed that kinship social support was negatively related to maternal trauma exposure severity, maternal PTSD symptom severity, child internalizing behaviors, and child externalizing behaviors. Additionally, kinship social support moderated the relationship between maternal trauma exposure severity and child internalizing behaviors. These results have implications in the implementation of interventions aimed at supporting diverse families facing trauma that incorporate extended family networks.     

Maternal postpartum depressive symptoms and infant externalizing and internalizing behaviors

Maternal postpartum depression has been shown to be one of the main predictors of externalizing and internalizing behaviors in toddlers and adolescents. Research suggests that presence of such behaviors can be observed as early as infancy. The current study uses longitudinal data from 247 mothers to examine the relationship between postpartum depressive symptoms at 8 weeks and the infant's externalizing and internalizing behaviors at 12 months. In unadjusted linear regression models, there were associations between postpartum depressive symptoms and infant externalizing behaviors (β = 0.082, SE = 0.032, p = 0.012) and internalizing behaviors (β = 0.111, SE = 0.037, p = 0.003). After controlling for potential confounding factors, including maternal age, race, education, home ownership, smoking status in the postpartum period, marital status, parenting stress, and happiness from becoming a parent, the associations between postpartum depressive symptoms and infant externalizing (β = 0.051, SE = 0.034, p = 0.138) and internalizing behaviors (β = 0.077, SE = 0.040, p = 0.057) were reduced and became non-significant. Furthermore, in these models the total amount of variance explained was 17.2% (p < 0.0001) for externalizing behaviors and 10.5% (p < 0.01) for internalizing behaviors; the only significant predictor of externalizing behaviors was maternal age (β = −0.074, SE = 0.030, p = 0.014), and of internalizing behaviors was white non-Hispanic ethnicity (β = −1.33, SE = 0.378, p = 0.0005). A combined effect of the confounding factors seems to explain the finding of no significant independent association between postpartum depressive symptoms and infant externalizing and internalizing behaviors.     

资质过剩感影响组织公民行为的情绪路径

本研究从员工情绪以及情绪调节的视角,考察了资质过剩感对员工组织公民行为的影响机制。通过对534名企事业员工的问卷调查数据进行分析,结果表明:员工的资质过剩感对其组织公民行为具有显著的消极作用;工作愤怒在资质过剩感与员工组织公民行为之间起部分中介作用;不同的情绪调节方式对员工资质过剩感与其工作愤怒的正向关系有不同的调节作用,认知重评方式有助于缓解资质过剩感对愤怒以及组织公民行为的消极影响,而表达抑制方式的调节作用恰恰相反。这一研究结果表明了情绪调节在工作领域中所发挥的作用,具有一定理论意义与实际价值。     

Crisis Assessment and Psychiatric Hospitalization of Children and Adolescents in State Custody

We investigated the clinical characteristics and placement decisions among a group of children who were wards of the state and had been evaluated for a crisis assessment. The sample consisted of 383 children and adolescents (ages 2-20 years) who were wards of the Illinois Department of Children and Family Services (DCFS). This study retrospectively reviewed the symptoms, risk factors, functioning and co-morbid variables, and placement or system characteristics of these children using a structured assessment tool, the Childhood Severity of Psychiatric Illness (CSPI). Results indicated that risk behaviors as rated on the CSPI, including suicidality, dangerousness, and runaway tendency, were significant predictors of psychiatric hospitalization. The importance of more widespread usage of standardized assessment tools in evaluating children's mental health needs is discussed.     

父母严厉管教与儿童问题行为的关系:儿童自我控制的中介作用

为探讨父母严厉管教、儿童自我控制与儿童问题行为间的关系,采用中文版亲子冲突解决策略量表、社会技能评定量表和儿童行为核查量表对济南市两所公立学校的1097名小学四到六年级儿童及其父母双亲进行测查。结果发现：（1）父母心理攻击和体罚与儿童自我控制均呈显著负相关,与儿童内化和外化问题行为均呈显著正相关,儿童自我控制与其内化和外化问题行为均呈显著负相关;（2）父亲心理攻击可以显著正向预测儿童内化和外化问题行为,母亲体罚可以显著正向预测儿童外化问题行为;（3）儿童自我控制在父亲心理攻击和母亲体罚与儿童内外化问题行为之间起中介作用,在母亲心理攻击和父亲体罚与儿童内外化问题行为关系间的中介作用不显著,中介作用模型不存在显著的儿童性别差异。综上,本研究发现父母严厉管教不仅直接影响儿童的内外化问题行为,而且会通过降低儿童自我控制水平间接导致儿童问题行为的增多。     

时间定价与主观时间流逝速度感对利他行为的影响

采用筛选图片时间任务作为被试利他意愿的指标,考察在两种主观时间流逝速度（时间飞逝和时间缓慢）条件下,被试（时间定价组和非时间定价组）对利他行为的影响。结果发现,非时间定价组在时间飞逝和缓慢条件下利他行为差异不显著,但是时间定价组在时间飞逝条件下比在时间缓慢条件下利他行为时间明显较短。结果表明,时间定价组在时间飞逝条件下充分显现时间的价值,减少利他时间,而在时间缓慢条件下,在可接受的时间成本范围内,被试表现出较为乐于助人,证实了主观时间流逝速度会对个体利他行为产生影响。

Are trait self-control and self-control resources mediators of relations between executive functions and health behaviors?

This study investigated associations between executive functions (i.e., inhibition, working memory, cognitive flexibility) and individual differences in self-control and health behaviors. We examined whether executive functions predict physical activity, sedentary activity, and healthy and unhealthy diets, and whether trait self-control and self-control resources mediate these associations. Three hundred and eighty-five participants completed a questionnaire assessing trait self-control and self-control resources, physical activity, sedentary activity, and healthy and unhealthy diets. They also performed three randomly ordered cognitive tasks, a stop-signal task (i.e., inhibition), a letter memory task (i.e., updating), and a number-letter task (i.e., switching). Structural equation modeling revealed that self-control resources predicted positively physical activity (R² = 0.08), negatively sedentary activity (R² = 0.03) and positively healthy diet (R² = 10). Moreover, trait self-control predicted positively healthy diet (R² = 0.10) and negatively unhealthy diet (R² = 0.19). Moreover, analyses revealed that switching significantly predicted self-control resources, and highlighted three totally mediated relations between this executive function and physical activity, sedentary activity and healthy diet. However, no evidence was found supporting associations between inhibition and updating, and health behaviors, or relations mediated by self-control for these executive functions. The findings suggest the importance of trait self-control and self-control resources for health behavior adoption and pave the way for studies exploring the role of the executive functions in an affective context.

The effects of conducting behavioral observations on the behavior of the observer

Behavior-analytic approaches to occupational safety are often effective for improving safety in organizations, and have been successful in a wide variety of settings. The effects of these safety processes are thought to arise primarily from the behavioral observation process and the delivery of feedback. Typically, supervisors or employee observers involved in behavioral safety implementations conduct observations. The present study was an attempt to assess the effects of conducting observations on an observer's safety performance. An ABC multiple baseline counterbalanced across two sets of behaviors was conducted in a simulated office. The target behaviors involved knee and back positions during lifts; back, shoulder, and feet positions while sitting; neck and wrist positions while typing; and neck position during phone use. Substantial improvements in safety performance occurred after participants conducted observations on a videotape of a confederate's performance. The possible behavioral functions responsible for this change, and the implications of these findings for applied settings, are discussed.
