This study addresses the following questions in cases of suspected child abuse and neglect (CAN) in children up to four years of age: 1) How many professionals intend to seek inter-organizational consultation? 2) What types of organizations do professionals prefer to consult? and 3) What factors can be identified as facilitator(s) or barrier(s) regarding inter-organizational consultation, based on professionals’ experiences? Professionals working with children in 101 organizations in a medium-sized Dutch city were invited to fill in an online questionnaire. The questionnaire included a vignette about a suspected case. Quantitative, qualitative, and social network analysis approaches were used to analyze the data. Seventy-eight questionnaires were available for analysis. Fifty-five respondents (71%) intended to seek inter-organizational consultation. Ten different organization types were mentioned. The most frequently mentioned organization was preventive child healthcare. In total, 82 text fragments from 39 participants were available to analyze barriers and facilitators to inter-organizational consultation, 60 fragments that entailed a facilitator and 22 fragments that entailed a barrier. The text fragments were subdivided into twelve factors. The three factors that were most often identified as a facilitator were ‘support’, ‘undertaking action’, and ‘regard’. Barriers were found in relation to all twelve factors. No specific barrier(s) stood out. This study demonstrated that most professionals are inclined to seek inter-organizational consultation when they suspect CAN. They are especially likely to seek consultation from preventive child health care organizations. Their experiences mainly revealed facilitators and few barriers. The implications for research and practice are also discussed.  相似文献

BackgroundAdverse childhood experiences (ACEs) are a potent risk factor. Despite these findings, studies have also recognized the importance of considering additional sources of genetic and environmental influence that cluster within families.ObjectiveTo properly control for latent sources of genetic and within-family environmental influences and isolate the association between ACEs and the following outcomes in adulthood: physical health, depressive symptoms, educational attainment, income attainment, alcohol problems, and antisocial behavior.Participants and SettingTwo independent samples of twins and siblings from the United States: the Midlife Development in the United States (MIDUS) study (N = 862) and the National Longitudinal Study of Adolescent to Adult Health (Add Health; N = 3112).MethodsSibling comparison models, which control for latent sources of genetic and within-family environmental influences, were estimated to examine whether differential exposure to ACEs was associated with the examined outcomes.ResultsFamilies that experienced more adversity also experienced more deleterious outcomes. However, siblings that experienced more adversity were no more likely to experience deleterious outcomes than their co-siblings. However, greater exposure to ACEs was associated with increases in depressive symptoms (Add Health). Additional models revealed that the similarity between siblings from the same family stemmed from latent sources of within-family environmental influences not captured by traditional ACEs measures.ConclusionsConsidering genetic influences and additional latent sources of within-family influences is crucial in isolating the effects of ACEs. Currently employed ACEs measures may not adequately capture the full range of impactful sources of family-level environmental influence.  相似文献

The use of corporal punishment (CP) is a strong risk factor for many poor outcomes for children including child maltreatment. The use of CP occurs within social contexts which are important to understand. Although it is known that perceived social norms regarding CP are related to its use, the specific role that a mother’s primary support person plays in influencing attitudes toward and use of CP remains unknown. The current study assessed linkages between maternal perceived social support in parenting and perceived injunctive norms of CP from her primary source of support, with maternal attitudes toward and use of CP. Survey data were collected from female primary caregivers (N = 436) of children age 2 to 7 years (mean age = 3.7) enrolled in Special Supplemental Nutrition Program for Women, Infants and Children (WIC) clinics in Southeastern Louisiana. Most frequently, the biological father of the child (37.9%) and the maternal grandmother of the child (24.2%) were identified as the participant’s primary source of social support in parenting. Perceived injunctive norms of this support person toward CP use were significantly and positively associated with attitudes toward, AOR = 5.97, 95% CI = [4.04, 8.82], and use of CP, AOR = 3.77, 95% CI = [2.55, 5.59]. However, perceived social support was not associated with these outcomes and also did not moderate these associations. Findings suggest that efforts to reduce maternal risk for child physical abuse and use of CP must include the mother’s primary source of social support if they are to be successful.  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

BackgroundMaternal childhood experiences of maltreatment affect parenting and have consequences for a child’s social-emotional development. Adolescent mothers have a higher frequency of a history of maltreatment than adult mothers. However few studies have analyzed the interactions between adolescent mothers with a history of childhood maltreatment and their infants.ObjectiveThe aim of the study was to examine the effect of maternal childhood experiences of maltreatment on mother-infant emotion regulation at infant 3 months, considering both infant and mother individual emotion regulation and their mutual regulation.ParticipantsParticipants were 63 adolescent and young adult mother-infant dyads recruited at a hospital.MethodsThe mothers were administered the Adult Attachment Interview to evaluate reflective functioning and attachment and the Childhood Experiences of Care and Abuse was used to evaluate maternal childhood experiences of maltreatment. Mother-infant interactions were coded with a modified version of the Infant Caregiver Engagement Phases.ResultsDyads with mothers with childhood maltreatment (vs dyads with mothers with no maltreatment) spent more time in negative emotional mutual regulation (p = .009) and less time in positive and neutral mutual emotion regulation (p = .019). Cumulative maternal childhood experiences of maltreatment were associated positively with mother and infant negative states at individual and dyadic level and with the AAI scales of Passivity and Unresolved Trauma (p < .05). The effect of cumulative maternal childhood experiences of maltreatment on mother-infant emotion regulation was direct and not mediated by maternal attachment and reflective function.ConclusionsMaternal childhood experiences of maltreatment increase the risk connected to early motherhood, affecting mother-infant emotion regulation.  相似文献

BackgroundAdverse childhood experience (ACE) and intimate partner violence (IPV) have sustained, deleterious effects on physical and mental health. Few studies have examined how to help Latina survivors of ACEs and/or IPV regain control of their health.ObjectiveTo inform interventions for this population, we examined whether mastery of stress and patient activation mediate the relationship between a history of ACE and/or IPV and mental and physical health.Participants and settingWe recruited 235 Latina women (M age = 29.6, SD = 5.75) from primary care clinics.MethodFor this cross-sectional study, we used linear regressions to examine the association between ACEs, history of IPV, and health, and the sobel’s test to determine whether patient activation and mastery of stress mediated the relationships between ACEs, IPV, and health.ResultsMost women reported at least one ACE (61.7%, n = 137) and 22.2% (n = 55) reported a history of IPV. Mastery of stress mediated the relationship between ACE and physical health (b= -3.16 p = .002) and mental health (b= -3.83, p < .001). Mastery of stress also mediated the relationship between history of IPV and physical health (b= -2.62, p = .008) and mental health (b= -2.74, p = .006). Patient activation was not associated with a history of trauma or mental health.ConclusionWhile past experiences of trauma cannot be changed, results from this study suggest that improving an individual’s mastery of stress may be a point of intervention for improving mental and physical health among survivors of ACEs and IPV.  相似文献

BackgroundEmotional abuse is a form of maltreatment that most strongly predicts adult depressive symptoms in community samples. Introject theories suggest that some depressive symptoms stem from survivors having learned to treat themselves the way they were treated by their perpetrators.ObjectiveMalevolent introjects may undermine self-compassion, which may subsequently maintain feelings of shame. Thus, we hypothesized that self-compassion and shame would mediate the path from retrospective reports of maltreatment to concurrent depressive symptoms in adulthood.Participants and SettingParticipants were 244 adult community members and college students living in a Southwestern American metroplex.MethodWe ran a multiple mediator path model with emotional abuse as the independent variable. We specified four covariates: physical abuse, sexual abuse, physical neglect, and emotional neglect, and held constant the variance they explained in self-compassion, shame, and depression.ResultsOur final model accounted for 53.1% of the variance in adult depressive symptoms. A significant indirect effect from emotional abuse passed through both mediators and ended in adult depressive symptoms. We also found an indirect path from emotional neglect to depression passing through both mediators.ConclusionsIt appears emotional abuse and emotional neglect can undermine the formation of self-compassion. Low self-compassion predicts greater shame and depressive symptoms. Our model suggests self-compassion may be a particularly effective intervention point for survivors of emotional maltreatment.  相似文献

BackgroundSeveral studies have hypothesized that the pattern of health care utilization among maltreated children differ from others without the experience. However, the conclusions have not been consistent.ObjectiveThe study aims to examine whether the pattern of health care utilization among children 0–5 years old with maltreatment different from their counterparts without maltreatment in Taiwan.Subjects and SettingAll children born in 2007 in Taiwan.MethodThis is a population-based and case-controlled study. Cases are children under five years of ago with maltreatment-related diagnosis in the claims data of the National Health Insurance in Taiwan during the 2007–2013 period. For each case, there were 10 birth date-matched controls. Exposure variables include the number of injury or non-injury-related outpatients, emergency department (ED) visits, and hospitalization. Multivariate models were employed, with adjustment for sex, urbanization level, and comorbidities of children.ResultsOf children born in 2007, 382 had maltreatment-related diagnosis during the age of 0–5. The adjusted odds ratio (aOR) for having two or more ED visits with or without injury-related diagnosis is 3.52 (95% CI 1.75–7.07) and 2.0-0 (95% CI 1.47–2.72), respectively. Children with maltreatment also had significantly higher number of hospitalization without injury-related diagnosis and aOR for those having two more hospitalizations stands at 2.47 (95% CI 1.59–3.83).ConclusionsChildren with maltreatment when 0–5 years old had higher number of ED visits with injury-related diagnosis, as well as hospitalization without injury-related diagnosis. Recognition of the health care utilization is conducive to early identification of children with risk for maltreatment.  相似文献

ObjectiveTo determine if US child physical abuse and neglect injury rates changed from 2006 to 2014, whether definitive diagnoses of physical abuse and neglect were used more often over time, and what patient factors influenced definitive physical maltreatment diagnoses.MethodsNationally estimated rates of definitive and suggestive physical abuse and neglect injuries for children <10 years were generated using the Nationwide Emergency Department Sample, the National Inpatient Sample, and census estimates. Trends over time were evaluated, including the trend in the proportion of definitive diagnoses to all diagnoses (definitive plus suggestive). Logistic regression was used to evaluate whether patient characteristics and hospital patient volumes were associated with definitive versus suggestive diagnoses.ResultsThe population rates of child physical maltreatment medically treated injuries were unchanged from 2006 to 2014; the trends were not statistically significant for ED or hospitalized patients. Over time, physician definitive diagnoses as a proportion of all physical maltreatment diagnoses (definitive plus suggestive) increased in admitted children from 17.6% in 2006 to 22.0% in 2014 (p = 0.02). Older age, white race, lower income by zip code, and public insurance as well as larger patient volumes increased the odds of definitive rather than suggestive diagnoses of physical abuse and neglect injuries.ConclusionsDefinitive diagnoses of physical abuse and neglect increased over the study period and were associated with hospital volume and patient characteristics which may reflect provider experience and possible bias. The use of electronic medical records may have influenced the coding of definitive diagnoses.  相似文献
