Outcomes of psychotherapeutic and psychoeducative group interventions for children exposed to intimate partner violence

Witnessing violence toward a caregiver during childhood is associated with negative impact on children’s health and development, and there is a need for effective interventions for children exposed to intimate partner violence in clinical as well as in community settings. The current effectiveness study investigated symptom reduction after participation in two established group interventions (one community-based psychoeducative intervention; one psychotherapeutic treatment intervention) for children exposed to intimate partner violence and for their non-offending parent. The study included 50 children—24 girls and 26 boys—aged 4–13 years and their mothers. Child and maternal mental health problems and trauma symptoms were assessed pre- and post-treatment. The results indicate that although children showed benefits from both interventions, symptom reduction was larger in the psychotherapeutic intervention, and children with initially high levels of trauma symptoms benefited the most. Despite these improvements, a majority of the children’s mothers still reported child trauma symptoms at clinical levels post-treatment. Both interventions substantially reduced maternal post-traumatic stress. The results indicate a need for routine follow-up of children’s symptoms after interventions.

This article reports the findings of a classroom-based study into the effectiveness of various strategies designed to assist children at Key Stage 3 (11–14 years) to become better writers. It takes account of the attitudes of the pupils themselves and considers the role of the teacher in facilitating improvement in imaginative writing.     

Domestic violence,parental substance misuse and the decision to substantiate child maltreatment

Families that experience domestic violence and parental substance misuse are disproportionately involved with the child welfare system. Prior research suggests that child protective services (CPS) caseworkers are more likely to substantiate maltreatment allegations when domestic violence and parental substance misuse are identified during the investigation, pointing to one possible mechanism for this disproportionate involvement. While previous studies have relied on nationally representative data sets, the current study used administrative records from a large Midwestern child welfare agency that accounts for state-level variation in child welfare policy and practice. A total of 501,060 substantiation decisions made between 2009 and 2013 were examined to assess the influence of caseworker-perceived domestic violence and parental substance misuse on the decision to substantiate reported maltreatment. Results from multilevel modeling suggest that the identification of domestic violence and parental substance misuse during an investigation significantly increased the probability that an allegation would be substantiated. The implication of these findings for child welfare practice are considered in light of the fact that many child welfare agencies do not consider exposure to domestic violence and parental substance misuse in and of themselves to constitute child maltreatment.     

Children exposed to intimate partner violence: Identifying differential effects of family environment on children's trauma and psychopathology symptoms through regression mixture models

The majority of analytic approaches aimed at understanding the influence of environmental context on children's socioemotional adjustment assume comparable effects of contextual risk and protective factors for all children. Using self-reported data from 289 maternal caregiver-child dyads, we examined the degree to which there are differential effects of severity of intimate partner violence (IPV) exposure, yearly household income, and number of children in the family on posttraumatic stress symptoms (PTS) and psychopathology symptoms (i.e., internalizing and externalizing problems) among school-age children between the ages of 7–12 years. A regression mixture model identified three latent classes that were primarily distinguished by differential effects of IPV exposure severity on PTS and psychopathology symptoms: (1) asymptomatic with low sensitivity to environmental factors (66% of children), (2) maladjusted with moderate sensitivity (24%), and (3) highly maladjusted with high sensitivity (10%). Children with mothers who had higher levels of education were more likely to be in the maladjusted with moderate sensitivity group than the asymptomatic with low sensitivity group. Latino children were less likely to be in both maladjusted groups compared to the asymptomatic group. Overall, the findings suggest differential effects of family environmental factors on PTS and psychopathology symptoms among children exposed to IPV. Implications for research and practice are discussed.     

Analysis of the dynamics of the sharing knowledge between cooperating teacher and teacher-in-training： The partners＇ respective roles

Collaboration is becoming increasingly important in the realm of education （Novoa, 2004）. For instance, as soon as training is undertaken, the future teacher must develop an ability to cooperate in a pedagogical context. However, in order to learn to make a relevant contribution to a teaching team＇s undertakings and to provide innovative suggestions in pedagogical matters （Gouvernement du Quebec, 2001）, the student teacher needs solid backing from the cooperating teacher. A student teacher＇s willingness to reflect on and to question his own teaching practices will create a much more promising learning context （Portelance ＆ Durand, 2006）. Reciprocally, the cooperating teacher will make a positive contribution to the student teacher by accepting that his positions be questioned and even altered （Johnston, Wetherill ＆ Greenebaum, 2002）. It is the dynamics of sharing of knowledge and know-how in this partnership that retains our interest. From 2004 to 2007, the researchers carried out a study of the subject by examining four practicum sessions at high school level in a number of Quebec schools. To gather data, the researchers used written questionnaires, individual interviews, as well as recordings of conversations between student teachers and their cooperating teachers. These conversations pertain to the conception and to the execution, by the student teacher, of teaching-learning situations. These dialogues were integrally transcribed and processed by N＇vivo, software designed to analyze qualitative data. the researchers present a typology of the respective roles taken on by the two partners in their discussions. The cooperating teacher reveals himself to be an advisor, a transmitter of information and a teacher. The student teacher also takes on the role of transmitter of information, as well as that of reflective practitioner, among others, the researchers observed that the conversations are usually carried out in an egalitarian spirit and, in some cases, give rise to co-construction of practical knowledge.

Families in need of domestic violence services reported to the child welfare system: Changes in the National Survey of Child and Adolescent Well-Being between 1999–2000 and 2008–2009

This study aimed to determine if identification of intimate partner violence (IPV) has improved by caseworkers that investigate reports of child maltreatment and if mothers who are victims of IPV are more likely to report receipt of services. The study data were drawn from the two cohorts of the National Survey of Child and Adolescent Well-Being (NSCAW I and II), the first in 1999–2000 with a sample of 5,501 children reported for maltreatment and the second in 2008–2009 with a sample of 5,872 children reported for maltreatment. The analyses focused on IPV victimization of 3,625 mothers in NSCAW I and 3,351 mothers in NSCAW II whose children remained in home after the maltreatment investigation. Multiple group logistic regression was used to compare NSCAW I and II. A significant decrease in mother-reported IPV victimization (28.9–24.7%) was observed, representing a 15% decline. There were no significant changes in caseworker identification of history of domestic violence or active domestic violence. In both cohorts, substance abuse by the secondary caregiver was associated with a lower likelihood for the caseworker to miss a history of active domestic violence, while substantiation reduced the likelihood that the caseworker will miss active domestic violence. There were no changes in caseworkers’ service referral, or service receipt among victims. The next decade of efforts to reduce IPV and child maltreatment should focus simultaneously on increasing caseworkers’ ability to identify IPV and on funding needed services for families impacted by IPV and child maltreatment.     

Subtypes of exposure to intimate partner violence within a Canadian child welfare sample: Associated risks and child maladjustment

Children exposed to intimate partner violence (IPV) are at increased risk of experiencing behavioral difficulties including externalizing and internalizing problems. While there is mounting evidence about mental health problems in children exposed to IPV, most of the research to date focuses on IPV exposure as a unitary, homogeneous construct. The purpose of this study was to examine the association between subtypes of IPV exposure on child functioning and presence of harm within a child welfare sample. Given the evidence of the “double whammy” effect, co-occurring IPV exposure was also examined. Using data from the Canadian Incidence Study of Reported Child Abuse and Neglect – 2008 (n = 2,184) we examined whether specific IPV exposure subtypes or their co-occurrence resulted in a greater risk of child maladjustment. Information was obtained from child welfare workers’ reports. Caregiver and household risk factors were also examined. Co-occurring IPV exposure resulted in the greatest risk for reported child maladjustment. Exposure to emotional IPV and direct physical IPV were significantly associated with increased risk of internalizing problems and presence of harm. Caregiver mental health and lack of social support emerged as significant risk factors for behavior problems. This study adds to the evidence that exposure to subtypes of IPV may be differentially related to child functioning. Given that risk factors and child functioning is part of the decision-making framework for case worker referrals, this study provides important preliminary evidence about how the child welfare system operates in practice with respect to sub-types of exposure to IPV. These findings suggest that intervening with children exposed to different types of IPV may require a tailored approach.
