BackgroundAdverse childhood experiences (ACEs) are an identified risk factor for the social and emotional development of children. What is less known is the long-term effects of ACEs when poverty and ACEs coincide.ObjectiveUsing longitudinal cohort-panel data, we examined whether exposure to ACEs by the age of three among poor children would longitudinally result in behavioral problems at ages three, five, nine, and 15, after controlling for mothers’ socioeconomic status and their children’s characteristics.Participants and settingWe used a subsample of 2750 children and their parents living in urban poverty from the Fragile Families and Child Wellbeing study.MethodsLogistic regression modeling was used to obtain adjusted odds ratios of ACE categories predicting behavioral problems after accounting for family socioeconomic position.ResultsOur findings indicate that experiencing ACEs in early childhood was significantly associated with later behavioral outcomes from childhood to adolescence. Exposure to multiple ACEs before the age of three was significantly associated with the top-risk behavior group at age five; the odd ratios were 2.0 (CI = 1.3–3.1) and 2.9 (CI = 1.8–4.6) for two ACEs and three or more ACEs, respectively. At both ages nine and 15, children experiencing two or more ACEs had 1.9 to 3.2 times higher odds to demonstrate more the top 10th percentile of behavioral problems. Among covariates, mothers’ race and education, and children’s gender and temperament were identified as significant factors to determine behavior problems.ConclusionsThe findings support policies and programs for families with children who have experienced economic disadvantages and early childhood adversity.  相似文献

BackgroundPerceptions of security toward parents are related with internalized and externalized problems among victims of child sexual abuse (CSA). Alexithymia, which is difficulty in identifying and expressing feelings, is associated with the quality of parent-child relationships (Oskis et al., 2013) and behavior problems in children (Di Trani et al., 2013).ObjectiveThe current study tested the mediational role of alexithymia in the relationship between perceptions of security toward parents and behavior problems among CSA victims.Participants and methodUsing a short-term multi-informant prospective design, 263 victims of CSA aged 6–12 years completed the Kerns Security Scale (Kerns, Klepac, & Cole, 1996), which evaluates perceived attachment security to mothers and fathers. Parents completed the Child Behavior Checklist (Achenbach & Rescorla, 2001) at Time 1 to provide baseline scores of behavior problems and again four months later. At Time 2, parents also assessed the children’s alexithymia using the Children’s Alexithymia Measure (Way et al., 2010).ResultsPerceptions of security were both associated with alexithymia, as well as with internalizing and externalizing problems (p < .05). A mediational model showed that perception of security toward fathers outweighed the mother-child relationship in predicting children’s alexithymia. Path analysis revealed that the father-child relationship predicted decreased behavioral problems at Time 2 through a lower level of alexithymia. The model explained 46.9% of internalizing problems and 56.1% of externalizing problems (p < .05).ConclusionsThe findings support the relevance of alexithymia as an intervention target for CSA victims and underscore the importance of the father-child relationship.  相似文献

BackgroundEarly adversity and negative experiences in the adoptive family can put adopted children at risk for emotional and behavior problems.ObjectiveThis study analyzes the influence of children’s preadoptive history and adoptive parents’ characteristics on the psychosocial adjustment of nationally and internationally adopted children in Germany.Participants and settingThe survey included 172 adopted children aged between 24 and 145 months and their adoptive parents.MethodsParents provided information about preadoptive history. Information about emotional and behavior problems was obtained from the parental version of the Strengths and Difficulties Questionnaire (SDQ). Parental well-being was obtained through a composite score of three standardized measures (self-efficacy questionnaire, Perceived Stress Scale PSS-4, Brief Symptom Inventory BSI); parenting behavior was assessed with the Alabama Parenting Questionnaire (DEAPQ).Results12.5% of the adopted children scored in the clinical range of the SDQ. In a multiple regression analysis, the experience of maltreatment and neglect was the most important predictor of emotional and behavior problems at time of assessment, followed by pre- and perinatal risk and parental stress regulation difficulties, = .423, F(4, 128) = 28.539. Increases in the number of risk factors present were associated with a greater odd of children scoring in the clinical range of the SDQ.ConclusionsMost of the nationally and internationally adopted children in this sample were well-adjusted. Prenatal and preadoptive risk as well as stress regulation capacities of the main caregiver contributed to the child’s development. An accumulation of risks increased the likelihood of adjustment problems in adopted children.  相似文献

失地农民进入城市会面临某些心理不适问题,具体表现在居住变化、经济压力、就业不足与保障不力等导致的心理不安、焦虑与抵触失衡心理,以及社会交往产生的封闭自卑心理、城市认同感欠缺与市民意识缺失等。心理不适问题的产生既与城市体制性因素以及城市居民的偏见与歧视有关,也与失地农民自身人力资本不足、农村传统文化的持续影响有关。应该从物质层面做好就业与保障工作、从社会文化层面扭转生活方式与价值观念以及从个体心理层面构建心理调适机制来实现失地农民心理适应。  相似文献
