Negative parental attributions are related to parent and family stressors and are thought to be important predictors of subsequent disciplinary actions and, potentially, abusive parenting. We examined if negative parental attributions mediate the relation between daily stressors (i.e., low SES, parenting stress, partner-related stress) parents’ own history of child maltreatment, and harsh and abusive parenting. Mothers (n = 53) completed a computerized attribution task and reported on daily stressors, their own history of child maltreatment and their discipline strategies. Mothers’ negative parental attributions mediated the association between parenting stress (but not the other stressors) and harsh and abusive discipline. These finding implicate that interventions to decrease (the risk of) child abuse should not only focus on reducing abuse-related stressors, but also target negative parental attributions.  相似文献

BACKGROUND: A variety of definitions of child abuse and neglect exist. However, little is known about norms in the general population as to what constitutes child abuse and neglect or how perceived norms may be related to personal experiences. METHODS: We conducted a random-digit-dialed telephone survey of 504 Washington State adults. Respondents were asked whether they believed each of 34 behaviors, identified in focus groups as possibly physically, sexually or emotionally abusive or neglectful, constituted abuse or neglect. Then, they were asked whether they had experienced 33 of the behaviors. RESULTS: Five of the six behaviors with the highest levels of consensus were for sexual abuse, whereas only one emotionally abusive behavior had a high level of consensus (95% agreement). Consensus that spanking constituted abuse increased with severity. Those respondents who reported experiencing a particular behavior were significantly less likely to believe the behavior abusive for 11 of the 33 behaviors and more likely to believe the behavior abusive for two of the behaviors. Where comparisons were possible, there was a high level of consensus that behaviors identified as abusive in Child Protective Service operational definitions constituted abuse. CONCLUSIONS: Self-reported childhood experiences were associated with perceived norms about child abuse. A better understanding of community norms about child abuse and neglect may be helpful in communicating with the public or allow for better targeting of educational messages through the media, parenting education classes, and so forth.  相似文献

A history of childhood maltreatment is the most consistently reported characteristic of abusive parents. Retrospective research with nine women imprisoned for fatal child abuse revealed childhood histories of maltreatment. Detailed life histories indicated that the meaning of the abuse to the individual had an important impact on later abusive parenting. The types of childhood abuse varied. Childhood abuse was one in a set of factors contributing to abusive parenting. Retrospective studies underline the need for prospective research on long-term outcomes of childhood abuse.  相似文献

OBJECTIVE: The intergenerational transmission of child maltreatment is a controversial subject. Much of existing research is plagued with at least three fundamental weaknesses: (1) using case status to define subjects: (2) adopting a dichotomous perspective that does not consider the reality of maltreatment on various continua; and (3) using operational definitions that fail to differentiate between maltreatment subtypes. We controlled for these problems and examined the structure of child maltreatment and its influence on later parenting practices in an ethnically-diverse community sample. METHOD: Data from a community sample of parents (N = 383) were analyzed with a Structural Equation Modeling methodology. Reliable and valid continuous measures of child maltreatment (Child Trauma Questionnaire) and parenting practices (Parental Acceptance and Rejection Questionnaire) were used. RESULTS: Results revealed a moderately strong effect from a general factor of Child Maltreatment to a general factor of Poor Parenting for both mothers and fathers, supporting a common dysfunction transmission process. For mothers. Family Neglect by itself also led to poor parenting, and sexual abuse as a child led to aggressive parenting. For fathers, Child Maltreatment had a different structure, as sexual abuse was distinct from the factors of Family Abuse and Family Neglect. Also, for fathers, sexual abuse led to rejecting parenting practices. CONCLUSIONS: This study supports the intergenerational cycle of child maltreatment hypothesis in such a way that several weaknesses in much of existing research were controlled. Clinical implications and potential mechanisms of transmission are discussed.  相似文献

Child maltreatment negatively affects children's development and wellbeing. This study investigated the associations between child maltreatment (i.e., emotional neglect, emotional abuse, and physical abuse) and interpersonal functioning, including parent–child relationship, teacher–student relationship, and peer relationships among children with oppositional defiant disorder (ODD). A total of 256 children with ODD and their parents and class master teachers from Mainland China completed questionnaires. Results showed a negative correlation between emotional abuse (parent-reported) and children's interpersonal relationships with parents, teachers, and peers. Emotional neglect and physical abuse were related to poor parent–child relationships. Latent profile analysis revealed three profiles of child maltreatment among children with ODD. ODD children with more severe levels of one type of maltreatment were also more likely to have experienced severe levels of other types of maltreatment. Children with ODD who were in the group of high maltreatment had the poorest quality of interpersonal relationships. Our findings highlight the urgent need to prevent child maltreatment and promote more positive parenting in families with ODD children.  相似文献

OBJECTIVE: To understand the conceptualization of child abuse and attitudes on reporting behaviors of Hong Kong adults. METHODS: Cross-sectional telephone survey of 1,001 randomly selected subjects. MAIN RESULTS: There is a discrepancy between perceived prevalence and the ability to name different child abuse types without prompting: 79.9% named physical abuse, while 41.2% felt it was common: 21.0% named child neglect, while 76.9% felt it was common; 13.4% named psychological abuse, while 47.4% felt it was common; 6.8% named sexual abuse, while 23.5% felt it was common. Most respondents classified severe physical abuse situations as abusive (e.g., "severely injuring a child"). Other scenarios such as "mildly injuring a child" and neglect and psychological abuse scenarios (e.g., "leaving a young child alone at home" and "shouting at a child often") were often not classified as abusive. As regards case-reporting behavior, only about 40% would report abuse cases to authorities. Those who would not report abuse were less likely to classify abuse situations as abusive and more likely to think that seeking help is difficult, troublesome and unhelpful. CONCLUSIONS: The official reported prevalence figures for child abuse in Hong Kong should be interpreted with care, because underreporting is likely to be serious. Hong Kong people's conceptualization and awareness of what comprises child abuse is found to differ from official definitions. They are reluctant to report abuse cases, due to their perceived low efficacy of case reporting. Both the difference in conceptualization and the reluctance to report might partly be attributable to Chinese culture.  相似文献

OBJECTIVE: To present key findings from the Canadian Incidence Study of Reported Child Maltreatment (CIS) in sufficient detail to provide a basis for international comparisons in terms of forms and severity of maltreatment and the age and sex of victims. METHOD: A survey conducted in a random sample of 51 child welfare service areas across Canada tracked child maltreatment investigations conducted during the months of October to December 1998, produced a national sample of 7672 child maltreatment investigations. Information was collected directly from investigating workers on child and family background, perpetrator characteristics, severity and types of maltreatment and service and court outcomes of investigations. RESULTS: Forty-five percent of investigations were substantiated and in a further 22% of investigations maltreatment remained suspected. Primary reasons for investigation were physical abuse (31%), sexual abuse (11%), neglect (40%), and emotional maltreatment (19%). A larger proportion of physical abuse cases are isolated incidents involving older children and are more likely to lead to injuries. Sexual abuse, neglect and emotional maltreatment involve more chronic situations with children showing signs of emotional harm. Rates of investigated and substantiated maltreatment are lower in Canada compared to the United States, but are higher than rates reported in Australia. CONCLUSIONS: The CIS provides much needed information for developing a better understanding of the profile and needs of children and families investigated by child welfare authorities in Canada. The study also serves as a point from which international comparisons can be made.  相似文献

According to bystander theory, factors such as the community environment, collective efficacy, and history of adverse childhood experiences could be related to likelihood of reporting or intervening against maltreatment. An online survey was conducted with 946 general population Californians obtained through mixed-mode random probability and quota-based recruitment methods. Using an experimental vignette design, participants were randomly assigned to two scenarios: a) potential child abuse occurring in their neighborhood; b) potential child abuse in an unfamiliar neighborhood. Weighted multivariate logistic regression models assessed relationships between the vignette condition, collective efficacy, appraisal of the behavior, and likelihood of reporting or intervening. The results suggested that perceiving the vignette as occurring in your own neighborhood was associated with lower odds of viewing the behavior as appropriate and considering it abusive. Higher collective efficacy scores were associated with lower odds of viewing the incident as inappropriate but higher odds of personally intervening. Adverse childhood experiences were positively related to reporting the incident to child protective services and intervening. Bystanders may be more likely to give parents in their own neighborhood "the benefit of the doubt" by viewing their abusive behaviors as less severe, potentially leading to underreporting. Neighborhood collective efficacy might increase willingness to personally intervene, but not contact systems such as child protective services or police, suggesting that enhanced trust in communities does not extend to these institutions. Our findings have implications for neighborhood and education interventions to enhance understanding of and willingness to intervene on behalf of children.  相似文献

OBJECTIVE: Dissociation is linked to the experience of child maltreatment for adults and for school-aged children. The goals of the current paper were: First, to extend existing research and examine the link between child maltreatment and preschool-aged children; and second, to examine which subgroups of maltreated preschoolers are most likely to evidence dissociation. METHOD: A well-validated measure of dissociation in children, The Child Dissociative Checklist (CDC; Putnam, Helmers, & Trickett, 1993), was utilized in a sample of low SES maltreated and nonmaltreated preschoolers (N = 198). A measure of internalizing and externalizing symptoms was also utilized. The maltreated children were assessed for sexual abuse, physical abuse, neglect, and also for severity, chronicity, and multiple subtypes of maltreatment. RESULTS: The sexually abused, physically abused, and neglected groups each demonstrated more dissociation than did the nonmaltreated group. Dissociation in the clinical (psychopathological) range was associated with physical abuse. Moreover, maltreatment severity, chronicity, multiple subtypes, and internalizing and externalizing symptomatology were each related to dissociation. CONCLUSIONS: Child maltreatment is a factor in dissociation in preschool-aged children as it is in older children and in adults. Sexual abuse, physical abuse, neglect, severity, and chronicity are all implicated. Developmentally sensitive interventions that look beyond comorbidity with behavioral symptoms for dissociative preschool-aged children are needed.  相似文献

OBJECTIVE: The goal of this study was to identify links between observed conflict interactions and risk for child abuse and harsh parenting among a multiethnic sample of adolescent mothers (14-19 years) and young fathers (14-24 years). METHODS: Prior to childbirth (T1), observation-based relationship data were collected from 154 expectant adolescent couples as well as information about physical aggression between partners. Two years after childbirth (T2), data relevant to harsh disciplinary practices and child abuse-prone attitudes were collected from both young mothers and fathers. Multiple regression analyses were run to examine the correspondence between (a) couples' relationship quality prior to childbirth and (b) subsequent risk for harsh and potentially abusive parenting practices. RESULTS: Findings indicated that interpartner violence prior to childbirth predicted physically punitive parenting behavior for fathers, but not for mothers. Young mothers and fathers observed to be more warmly engaged with each other during their pre-birth couple interactions (T1) reported lower rates of physically punitive parenting behavior with their children at T2. Couples' hostility at T1 predicted fathers' level of observed hostility toward his child during a structured play activity at T2. CONCLUSIONS: Results underscore the importance of addressing the quality of couples' relations as means of preventing dysfunctional parenting practices among adolescent mothers and their partners. Adolescent mothers and their partners are at heightened risk for engaging in dysfunctional parenting, including child abuse. Focusing on pregnant adolescents and their partners, this study sought to identify interpersonal predictors of child abuse risk. Although this study did not involve administering prevention or intervention services, the goal was to test hypotheses that would inform the development of programs for young at-risk couples. PRACTICE IMPLICATIONS: The decision to recruit young couples prior to childbirth was based on the presumption that this period of time could provide a window of opportunity to administer couple-based child abuse prevention programs. Consistent with previous research on marital relations and parenting, results of this study support the idea that efforts to develop and administer preventive-intervention programs targeting at-risk couples could help reduce the occurrence of harsh parenting behavior and abuse.  相似文献

OBJECTIVE: Teachers' expectations about the effects of physical and emotional abuse on children's classroom behaviors were examined in this study. Not only do teachers have to decide if a particular child is the victim of abuse, they may also have to contend with changes in that child's classroom behavior. METHOD: Teachers generated what they thought were typical outcomes of physical and emotional abuse on children's classroom behavior. RESULTS: Responses generally fell into the following categories: lowered self-esteem, heightened aggression, academic difficulties, and poor social interaction skills. Teachers who mentioned lowered self-esteem were more likely to generate it as the result of emotional abuse rather than physical abuse. CONCLUSIONS: Teachers' expectations generally mirrored research findings as to the actual effects of child abuse. Suggestions are made to incorporate the results in training programs designed to increase teachers' self-confidence in reporting potential cases of child abuse.  相似文献

OBJECTIVE: The aims of the study were to: determine the attitudes of parents, pediatric residents, and medical students from a Turkish population toward childhood disciplinary methods; ascertain the association of participants' abusive childhood history with their attitudes toward discipline; and assess their attitudes about disciplinary actions, which should be reported as abuse. METHOD: A cross-sectional survey was conducted in Ankara University School of Medicine, Department of Social Pediatrics. Sixty-five parents, 39 pediatric residents, and 106 medical students completed a questionnaire (Survey of Standards of Discipline). This questionnaire was designed to measure sociodemographic characteristics, attitudes toward childhood disciplinary practices, and abusive childhood experiences. There were 43 different disciplinary acts in this questionnaire. The participants were expected to give responses to these acts in three categories: (a) acceptable as discipline; (b) unacceptable as discipline; and (c) unacceptable as discipline-would report to authorities as child abuse. Based on the responses to this questionnaire, we developed the Severity Scale. Using this scale, physical severity scores, verbal severity scores, and total severity scores were measured for each participant. RESULTS: None of the participants accepted life-threatening practices as discipline, but some declared certain abusive disciplinary practices as acceptable. Some forceful disciplinary methods were not considered as reportable by participants. All severity scores of both residents and students were found to be higher than those of the parents (for verbal severity scores p=.042). Also, both verbal and physical severity scores of parents with one child were higher than those of parents with two children (for verbal severity scores p=.044). Ninety-one participants (43.3%) indicated that beating was an acceptable form of discipline. Of parents, 66.9% reported abusive childhood history by their own criteria. Of medical students with an abusive childhood experience, 56.5% accepted beating as appropriate (p=.001). Both verbal and physical severity scores were found to be higher in participants with abusive childhood history. CONCLUSIONS: Abusive childhood history and lack of education regarding appropriate discipline techniques are linked to the acceptance of certain physical discipline practices. Turkey's cultural and traditional norms may be associated with the use of physical punishment, and in some cases, physical abuse. The lack of awareness of abusive discipline methods among physicians constitutes problems for child protection and must be addressed. Thus, educational programs on child disciplinary practices are required to provide an increased awareness of child abuse among health professional trainees and parents in Turkey.  相似文献

OBJECTIVE: The goals of this current project were to expand and elaborate on the results of Varia, Abidin, and Dass' (1996) study to better understand what historical parenting factors may contribute in creating a "Minimizing" perception of childhood psychological abuse. A second objective included examining the association between perceptual styles and adult ratings of adult relationship satisfaction. METHOD: Ninety individuals from a non-clinical adult sample completed self-report questionnaires regarding psychological maltreatment and adult relationship satisfaction. Three groups were created and compared using analysis of variance. The groups were (I) "Non-Abused," consistent reporters of no abuse; (II) "Acknowledgers," consistent reporters of abuse; and (III) "Minimizers," reporters of abuse, but do not label themselves as having been abused. RESULTS: Results indicated a continuum effect with the Non-Abused individuals reporting the highest level of maternal warmth and affection, the Acknowledgers reporting the lowest, with the Minimizers in the middle. The Non-Abused group reported the healthiest adjustment in terms of adult relationship satisfaction. While Minimizers and Acknowledgers reported similar levels of psychologically abusive experiences, Acknowledgers reported more difficulties with adult relationships. CONCLUSIONS: This study highlights the importance of studying Minimizers, a group which describes abusive events but minimizes the meaning and scope of these experiences. The relatively higher levels of maternal care which the Minimizers reported is hypothesized to be associated with their perceptions that they were not abused and acted as a protective factor associated with better quality adult relationships. The varying degrees of nurturance and care in the early family environment of abused individuals is speculated to be associated with distinct perceptual styles.  相似文献

Parents referred to child welfare services for child maltreatment often struggle against chronic risk factors including violence, substance abuse, mental health concerns, and poverty, which impinge upon their ability to be sensitive caregivers. The first line of intervention within the child welfare context is to modify parenting behavior. This scoping review comprehensively surveyed all available literature to map the extent and range of research activity around the types of interventions available within a child welfare context to parents of infants and toddlers (0–5 years of age), to identify the facilitators and/or barriers to the uptake of interventions, and to check that interventions match the risk factors faced by parents. This scoping review engaged in stringent screening of studies based upon inclusion/exclusion criteria. Sixty-five articles involving forty-two interventions met inclusion criteria. Interventions generally aimed to improve parenting practices, the relationship between parent and child, and/or attachment security, along with reducing child abuse and/or neglect. A notable finding of this scoping review is that at present, interventions for parents of children ages 0–5 involved with the child welfare system are most frequently measured via case study and quasi-experimental designs, with randomized control trials making up 26.2% of included study designs.  相似文献

Teachers are potentially helpful resource persons for large numbers of sexually abused children who may have difficulty disclosing abuse, particularly to family members. In the present study, the effectiveness of a 6-hour teacher training workshop on child sexual abuse prevention was evaluated. Responses of 26 female elementary teachers who participated in the workshop were compared to responses of 19 control teachers on several pre-, post-, and follow-up measures. Relative to controls, trained teachers demonstrated significant increases from pre- to post-testing in knowledge about child sexual abuse and pro-prevention opinions. On a post-only vignettes measure, trained teachers were better able than control teachers to identify behavioral indicators of abuse and suggest appropriate interventions for hypothetical sexually abused children. Over a 6-week follow-up period, trained teachers read more about child abuse than control teachers but did not differ on other behavioral dimensions such as reporting suspected abuse cases. Further research will examine the effects of additional teacher training over an extended follow-up period.  相似文献

ObjectiveThe main purpose of this paper is to use the Brassard and Donovan [Brassard, M. R. & Donovan, K. L. (2006). Defining psychological maltreatment. In M. M. Freerick, J. F. Knutson, P. K. Trickett, & S. M. Flanzer (Eds.), Child abuse and neglect: Definitions, classifications, and a framework for research (pp. 151–197). Baltimore, MD: Paul H. Brookers Publishing Co., Inc.] framework to examine and describe the nature of emotional abuse experienced by a sample of urban, ethnically diverse male and female youth (N = 303) identified as maltreated by a very large public child welfare agency.MethodsCase record abstraction was conducted on the DCFS records of these maltreated youth using the Maltreatment Case Record Abstraction Instrument (MCRAI) which was based on the work of Barnett et al. [Barnett, D., Manly, J. T., & Cicchetti, D. (1993). Defining child maltreatment: The interface between policy and research. In D. Cicchetti & S. L. Toth (Eds.), Advances in applied developmental psychology: Child abuse, child development and social policy (pp. 7–73). Norwood, NJ: Ablex Publishing Corp.] as modified by English and LONGSCAN [English, D. J., & the LONGSCAN Investigators. (1997). Modified maltreatment classification system (MMCS). Retrieved from http://www.iprc.unc.edu/longscan/]. Fifteen items of parental behavior deemed emotionally abusive were coded and organized into four subtypes of emotional abuse (spurning, terrorizing, isolating, exploiting/corrupting) using the Brassard and Donovan (2006) framework.ResultsUsing this coding system, almost 50% of the sample were found to have experienced emotional abuse in contrast to 9% identified at the time of referral by DCFS. Most of the emotionally abused youth also experienced physical abuse (63%) and/or neglect (76%) as well. The most frequent subtype of emotional abuse experienced was terrorizing. Most youth experienced more than one subtype.ConclusionsEmotional abuse, while frequent, was seldom the focus of the child protection services investigation. The nature of this abuse was not minor, but rather likely to be dangerous to the mental health and well-being of these children. Further more emotional abuse, in this sample of young adolescents, at least, was likely to be accompanied by other forms of maltreatment, especially physical abuse and/or neglect. These findings have important implications for practice and the direction of future research.Practice implicationsAll those who interact with child welfare clients must recognize the prevalence of emotional abuse in maltreated children so that appropriate interventions are instituted. Screening for emotional abuse should be part of all intake referrals and when confirmed should be noted in official records. When children are placed, foster parents (both kin and non-kin) need training on the prevalence and consequences of emotional abuse, and strategies to help their foster children recover from the aftermath. When children remain with maltreating parents, emotional abuse should be a focus of the interventions designed to help maltreating parents with more effective parenting strategies and also should be a focus of the interventions designed to help the child recover from the consequences of maltreatment.  相似文献

OBJECTIVE: Seeking to discern optimal programmatic strategies and inform the "universal versus targeted" debate in early home visitation services to prevent physical child abuse and neglect, a meta-analysis was conducted examining enrollment approaches in early home visitation studies and their reported outcomes. METHOD: Quantitative meta-analytic techniques were used to compare effect sizes from 19 controlled outcome studies across screening-based and population-based enrollment strategies. Effect sizes were calculated on protective services data and on child maltreatment related measures of parenting. RESULTS: On protective services report data, population-based studies reported a weighted mean effect size attributable to early home visitation of +3.72%, in comparison to -.07% for screening-based studies. On child maltreatment related measures of parenting, population-based studies reported a weighted mean effect size (r) attributable to early home visitation of +.092, in comparison to +.020 for screening-based studies. CONCLUSIONS: The findings indicate that population-based enrollment strategies appear favorable to screening-based ones in early home visitation programs seeking to prevent physical child abuse and neglect. It may be that psychosocial risk screens serve to enroll higher proportions of families for which early home visitation services are less likely to leverage change, and to exacerbate a mismatch between early home visitation service aims and family needs.  相似文献

OBJECTIVE: The main objective was to know social representations about child maltreatment (severity, etiology, and intervention strategies) of the general population and the professionals working with children in the Caribbean area of Colombia. METHOD: Sample was composed for 402 participants. From this pool of participants, 111 of them were working in child protection, 95 worked with children but not in the child protection system and 196 pertained to the general population. All participants answered to a questionnaire composed by 86 items. The questionnaire was developed to assess (1) the perceived severity of different typologies of child abuse, (2) opinions about risk factors for child maltreatment and sexual abuse, and (3) opinions about the most adequate ways of intervention with perpetrator of child abuse. RESULTS: Sexual abuse is considered as the most severe typology of child maltreatment and emotional abuse is considered as more severe than physical abuse. No differences between groups were found in perceived severity of typologies of child maltreatment. Differences in the social representation about the etiology of child maltreatment were found. Professionals working in the child protection system give more value to characteristics of parents and to the socio-economic and familiar environment in the etiology of child maltreatment than participants from the general population. Prevention and treatment programs for abusers were considered as the more relevant strategies against child maltreatment. DISCUSSION: Findings of present study suggest that social representations about child maltreatment of general population and professionals from the Caribbean area of Colombia are similar than social representation observed in other regions and countries. It is important to take into account that child labor and child poverty were considered as non-severe typologies of child maltreatment. Moreover, findings suggest that people from general population in the Caribbean area of Colombia have a relevant knowledge about agencies working for child protection.  相似文献

Studies concerning parenting styles and disciplinary practices have shown a relationship between both factors and bullying involvement in adolescence. The scarce available evidence suggests that abusive disciplinary practices increase teenagers’ vulnerability to abuse in school or the likelihood of them becoming abusers of their peers in the same context. However, there is a lack of knowledge about the indirect effect of parenting styles in adolescents’ bullying involvement through disciplinary practices, although a relationship between parenting styles and disciplinary practices has been shown. The aim of this research was to determine the mediating role of punitive parental discipline (physical punishment and psychological aggression) between the dimensions of parents’ parenting styles and their children's involvement in bullying victimization and aggression. We used a sample comprising 2060 Spanish high school students (47.9% girls; mean age = 14.34). Structural equation modeling was performed to analyze the data. The results confirmed the mediating role of parental discipline between the parenting practices analyzed and students’ aggression and victimization. Significant gender-related differences were found for aggression involvement, where boys were for the most part linked to psychological aggression disciplinary practices and girls to physical punishment. Victimization directly correlated with parental psychological aggression discipline behavior across both sexes. In conclusion, the results seem to suggest that non-democratic parenting styles favor the use of punitive discipline, which increases the risk of adolescents’ bullying involvement. Therefore, intervention programs must involve parents to make them aware about the important role they play in this process and to improve their parenting styles.  相似文献
