Beliefs about learning and physical difficulties were explored in 50 younger children (M = 5.6, SD = 1.0 years) and 50 older children (M = 9.5, SD = 1.1 years). Participants were asked why they thought some children had learning or physical difficulties and whether children with these difficulties would always have them. The majority of older children were able to generate one or more ideas about the causes of learning and physical difficulties, but 58% of the younger children did not know the causes of learning difficulties and 42% did not know the causes of physical difficulties. Younger and older children thought that learning difficulties could be overcome with increased effort on the part of parents, teachers, and child, whereas physical difficulties were believed to be beyond anyone’s control. Results suggest that some aspects of children’s knowledge about causes and outcomes of learning and physical difficulties are limited. Research is needed to determine whether beliefs and misconceptions about learning and physical difficulties are associated with the quantity and quality of interpersonal interactions, and to determine the sources of children’s information as well as the accuracy of these sources.  相似文献

BackgroundPrior researches have implicated a relationship of recidivism with childhood trauma (CT) and emotional intelligence (EI). However, the internal mechanism by which CT and EI influence the recidivism has not been examined.ObjectiveThis study aimed to map the road from CT and EI to recidivism in Chinese male offenders.Participants and settingThree thousand one hundred and eighty-one Chinese adult male offenders participated in this study and completed Childhood Trauma Questionnaire (CTQ) and Wong Law Emotional Intelligence Scale (WLEIS). Recidivism was quantified by the number of convictions according to official records.MethodsAfter controlling for age, education levels, family criminal history, and nature of offence, logistic regression sanalysis was performed to examine the effects of CT and EI on severity of recidivism. Structural Equation Modeling (SEM) was applied to explore the mediation model between CT, EI and recidivism.ResultsLogistic regression model shows a significant effect of CT (OR = 1.008, p < 0.01), rather than EI, on recidivism. SEM supported a full mediating effect of CT in the relationship between EI and severity of recidivism.ConclusionsOur findings suggest that EI has no direct effect on the recidivism, but exerts indirect influence on the recidivism through the mediating role of childhood trauma.  相似文献

BackgroundChildren who experience Child Abuse and Neglect (CAN) are at an increased risk of becoming a victim of Intimate Partner Violence (IPV) or a perpetrator of IPV or CAN. Moreover, maltreated children are at risk for developing long-lasting trauma symptoms, which can subsequently affect their own children’s lives. Understanding the mechanisms of the intergenerational transmission of violence and trauma is a prerequisite for the development of interventions.ObjectiveWe examine whether the relation between historical CAN and current trauma symptoms of mothers is mediated by current IPV. Furthermore, we investigate whether current CAN mediates the relation between current maternal trauma symptoms and child Post-Traumatic Stress Disorder (PTSD) symptoms. These mechanisms are compared for mothers and fathers.ParticipantsWe have recruited 101 fathers and 360 mothers (426 children, 50% boys, mean age 7 years) through child protection services.MethodsRespondents completed questionnaires about IPV, (historical) CAN and trauma symptoms.ResultsStructural equation models revealed that historical CAN of father and mothers was related to trauma symptoms. Only for mothers, this association was mediated by IPV. Trauma symptoms of both fathers and mothers were related to child PTSD symptoms. This effect was not mediated by current CAN.ConclusionIn violent families, maternal and paternal trauma can be transmitted over generations. However, intergenerational transmission of violence is found for mothers only. When family violence is reported, professionals should take the violence into account, as well as the history of parents and trauma symptoms of all family members.  相似文献

BackgroundAfrican American children are overrepresented in foster care at twice to three times the rate of white children. Scholars argue that racism and oppression underlie disproportionality (Križ & Skivenes, 2011).ObjectiveThis study explored disproportionality as seen through the eyes of African American parents in the child welfare system. The aim was to understand why African American families are over-represented in child custody statistics and to improve family and parenting support for African American communities.Participants & SettingParticipants included twenty-one African Americans--12 women and 9 men, two of whom were foster parents and 19 of whom were parents involved with child welfare services. All participants reside in two impoverished areas in southern United States. Focus groups were used to collect data and were conducted at a community center.MethodsThe method of analysis was constant comparison analysis (Strauss) and thematic analysis of the focus group discussions in the context of institutional policy.FindingsSix themes (profound lack of trust; overwhelming trauma; severe and persistent poverty; health and mental health; socio-economic conditions; and sense of social isolation were identified, along with three participant suggestions to improve child welfare services (family support services, economic revival, and better communication).ConclusionsIn the current study we note the strong link between poverty, child maltreatment, and child removal and conclude with an exploration of practice and policy implications with recommendations for a way forward. The need for culturally competent and trauma informed child welfare services is also discussed.  相似文献
