Understanding the Covariation Among Childhood Externalizing Symptoms: Genetic and Environmental Influences on Conduct Disorder,Attention Deficit Hyperactivity Disorder,and Oppositional Defiant Disorder Symptoms

Conduct disorder (CD), attention deficit hyperactivity disorder (ADHD), and oppositional defiant disorder (ODD) are common childhood externalizing disorders that frequently co-occur. However, the causes of their comorbidity are not well understood. To address that question, we analyzed data from > 600 Finnish twin pairs, who completed standardized interviews at age 14. Behavior genetic methods were used to examine how genetic/environmental factors contribute to each disorders symptoms and to their covariation. We found significant genetic effects on each disorder with only modest evidence of shared environmental influences. Our data suggest the comorbidity among CD, ADHD, and ODD is primarily explained by shared genetic influences; however, each disorder was also under unique genetic influence, supporting the distinction of each disorder.     

校园排斥对初中生内外化问题的影响:同伴关系与核心自我评价的中介作用

该研究探讨了校园排斥和初中生内外化问题的关系,结合资源保存理论,进一步考察同伴关系（条件性资源）与核心自我评价（人格特质资源）对该效应的链式中介作用。采用青少年校园现实受排斥量表、同伴关系量表、核心自我评价量表、焦虑抑郁量表和外化行为倾向量表,对辽宁省2所中学540名初中生进行调查。结果表明：（1）校园排斥对于初中生的内化及外化问题均具有正向预测作用;（2）同伴关系、核心自我评价在校园排斥与内化问题中起完全中介作用,而在校园排斥与外化问题中起部分中介作用。具体而言,校园排斥通过三条路径影响内外化问题：一是同伴关系的单独中介作用;二是核心自我评价的单独中介作用;三是同伴关系—核心自我评价的链式中介作用。     

Intensive Child-Centered Play Therapy for Children on the Autism Spectrum: A Pilot Study

To investigate the effectiveness of intensive child-centered play therapy (CCPT) for children diagnosed with autism spectrum disorder (ASD), the authors randomly assigned 23 children with diagnosed ASD and symptoms of ASD on the Social Responsiveness Scale–2nd Edition (Constantino, 2012), to an intensive CCPT condition (n = 12) or a no-intervention control group (n = 11). Children who participated in 24 sessions of CCPT showed a statistically significant decrease in ASD core symptoms and behavioral symptoms, such as externalizing problems, attention problems, and aggression, compared with children in the control group. Implications are discussed.     

儿童外部问题行为稳定性的研究

儿童早期外部问题行为对后期的学业、行为和同伴关系以及成人期的生活都有消极的影响。探讨外部问题行为的起源、影响因素和发展机制,对考察童年期外部问题行为是否可预测将来的问题、评估干预和预防措施的必要性和有效性,都是必不可少的。文章阐述了儿童外部问题行为稳定性的有关概念,介绍了外部问题行为的发展趋势、“童年期开始的”和“青春期开始的”外部问题行为的发展路径、行为遗传学研究成果以及影响外部问题行为稳定性的因素,并指出了这类研究对治疗和干预的意义     

Childhood Predictors of Long-Term Tic Severity and Tic Impairment in Tourette’s Disorder

Tics peak in late childhood and decline during adolescence. Yet, for some with Tourette’s disorder, tics persist into adulthood. We evaluated childhood predictors of adult tic severity and tic impairment, and change over time. Eighty adolescents/adults were evaluated 11 years following a randomized-controlled trial of behavior therapy. An independent evaluator rated tic severity and tic impairment at baseline, posttreatment, and long-term follow-up. At baseline, parents completed demographics/medical history, and youth tic, internalizing, and externalizing symptom ratings. Youth rated premonitory urge severity and family functioning. After controlling for prior tic treatment effects, female sex and higher tic severity predicted higher tic severity in adulthood; and female sex, no stimulant medication use, higher tic severity, and poorer family functioning predicted higher tic impairment. Higher tic severity and premonitory urge severity predicted smaller reductions in tic severity, whereas higher externalizing symptoms predicted greater reduction in tic severity. Female sex predicted smaller reduction in tic impairment, and externalizing symptoms predicted greater reduction in tic impairment. Female sex and childhood tic severity are important predictors of tic severity and tic impairment in adulthood. Family functioning, premonitory urge severity, and tic severity are important modifiable targets for early or targeted intervention to improve long-term outcomes.     

The anger–distress model of temper tantrums: associations with emotional reactivity and emotional competence

The goals of this investigation were (a) to assess the structural validity of the anger–distress model of temper tantrums, and (b) to examine the associations among temper tantrums, emotional reactivity and emotional competence in a community sample of preschoolers. A parent‐report measure, the Temper Tantrum Grid, was used to measure the frequency of common tantrum behaviours. Laboratory and parent‐report measures of emotional reactivity and emotional competence were administered. Confirmatory factor analysis supported the proposal that anger and distress are separate but overlapping tantrum processes. Correlation analyses showed that temper tantrum anger and distress were related to emotional reactivity and emotional competence. There was no evidence to support the notion that emotional competence moderated the effect of emotional reactivity on temper tantrums. In contrast, emotional competence was a significant mediator of the association between emotional reactivity and temper tantrums. Overall, the results support the anger–distress model of temper tantrums. The findings suggest that children's temper tantrums are systematically related to the overall organization of emotion and behaviour in preschool children.

The Longitudinal Interplay of Psychopathology and Social Competence During Chinese Children's Transition to Preschool

The present study examined the longitudinal relations between psychopathology and social competence in a sample of 115 Chinese children during the transition to preschool initiated in their third year of life. Social competence was assessed by maternal reports at three months after preschool entry (T1) and at the end of the first (T2) and second (T3) preschool years. Internalizing and externalizing symptoms were assessed by maternal reports at T1 and T2. The results showed that T1 externalizing predicted rank‐order decreases in social competence from T2 to T3. T1 Internalizing predicted rank‐order decreases in social competence from T1 to T2 but growth of competence from T1 to T3 and rank‐order increases in competence from T2 to T3. Rank‐order decreases in internalizing from T1 to T2 also predicted rank‐order increases in social competence from T2 to T3. These longitudinal relations held across gender and proved robust to the inclusion of broad individual and family process variables as covariates. Copyright © 2012 John Wiley & Sons, Ltd.     

The Mediational Role of Effortful Control and Emotional Dysregulation in the Link Between Maternal Responsiveness and Turkish Preschoolers' Social Competency and Externalizing Symptoms

This cross‐sectional study relied on circumscribed measures of emotion regulation and dysregulation to examine their role in mediating the associations of maternal responsiveness and effortful control with social competency and externalizing symptoms. We examined those associations in an understudied cultural context, Turkey, with 118 preschoolers. Emotion regulation and dysregulation showed differential associations with broad indices of self‐regulation such that emotion dysregulation predicted both low social competency and high externalizing symptoms but emotion regulation was only associated with high social competency. Effortful control was unrelated to emotion regulation but was associated with lower levels of emotion dysregulation. Effortful control had both direct and mediated associations with externalizing and social competency (mediated by lower emotion dysregulation). Findings also showed that maternal responsiveness was associated with better social competency and lower externalizing. Those associations were both singly (through effortful control) and doubly mediated (through effortful control and lower emotion dysregulation), similar to US samples. The study contributes to a better understanding of the factors and mechanisms that speak to children's self‐regulation. Copyright © 2013 John Wiley & Sons, Ltd.
