The Relationship of Reflective Functioning to Parent Child Interactions in a Sample of Fathers with Concurrent Intimate Partner Violence Perpetration and Substance Abuse Problems

This study is the first to examine reflective functioning (RF) and direct parent–child interactions of fathers with concurrent intimate partner violence (IPV) perpetration and substance abuse (SA) problems. Twenty-four fathers, with children between the age of one and seven, completed a structured interview to assess RF, self-report measures of hostile-aggressive parenting behaviors, IPV perpetration severity, SA severity, and a coded play session with their children. Results of three simultaneous multiple regressions revealed that RF in fathers was not associated significantly with observed parenting behaviors. However, fathers’ SA severity emerged as a significant predictor for child avoidant behavior and dyadic tension, and fathers’ IPV perpetration severity contributed unique variance to child avoidant behavior and dyadic constriction. These results suggest that fathers’ SA severity and IPV perpetration behaviors may be more salient factors in predicting their father-child interactions than paternal RF.     

Population structure of Y chromosome SNP haplogroups in the United States and forensic implications for constructing Y chromosome STR databases

A set of 61 Y chromosome single-nucleotide-polymorphisms (Y-SNPs) is typed in a sample of 2517 individuals from 38 populations to infer the geographic origins of Y chromosomes in the United States and to test for paternal admixture among African-, European-, Hispanic-, Asian-, and Native-Americans. All of the samples were previously typed with the 11 core U.S. Y chromosome short tandem repeats (Y-STRs) recommended by SWGDAM, which revealed high levels of among ethnic group variation and low levels of among-population-within-ethnic-group variation. Admixture estimates vary greatly among populations and ethnic groups. The frequencies of non-European (3.4%) and non-Asian (4.5%) Y chromosomes are generally low in European-American and Asian-American populations, respectively. The frequencies of European Y chromosomes in Native-American populations range widely (i.e., 7-89%) and follow a West to East gradient, whereas they are relatively consistent in African-American populations (26.4+/-8.9%) from different locations. The European (77.8+/-9.3%) and Native-American (13.7+/-7.4%) components of the Hispanic paternal gene pool are also relatively constant among geographic regions; however, the African contribution is much higher in the Northeast (10.5+/-6.4%) than in the Southwest (1.5+/-0.9%) or Midwest (0%). To test for the effects of inter-ethnic admixture on the structure of Y-STR diversity in the U.S., we perform subtraction analyses in which Y chromosomes inferred to be admixed by Y-SNP analysis are removed from the database and pairwise population differentiation tests are implemented on the remaining Y-STR haplotypes. Results show that low levels of heterogeneity previously observed between pairs of Hispanic-American populations disappear when African-derived chromosomes are removed from the analysis. This is not the case for an unusual sample of European-Americans from New York City when its African-derived chromosomes are removed, or for Native-American populations when European-derived chromosomes are removed. We infer that both inter-ethnic admixture and population structure in ancestral source populations may contribute to fine scale Y-STR heterogeneity within U.S. ethnic groups.     

Symptom Patterns among Youth Exposed to Intimate Partner Violence

Children and adolescents exposed to intimate partner violence display a broad range of symptoms. We sought to differentiate symptom patterns and predictors of these patterns using a person-oriented approach. Previous cluster analysis research of exposed youth was extended to include youth PTSD symptoms and trauma history. Participants were 74 mothers who had received a police call for domestic violence, and who had a child between 2 and 17 years old. Cluster analysis was used to identify four symptom patterns among exposed youth: Typical, Asymptomatic, General Distress, and Acute PTSD. These patterns were replicated in separate cluster analyses with younger and older participants. Symptom patterns were differentiated by maternal distress, maternal aggression, and youth trauma history, but not by male partner aggression. Implications for assessment and treatment of youth exposed to intimate partner violence, and suggestions for further research, are discussed.     

Parental Representations in the Play of Preschool Aged Witnesses of Marital Violence

The play of young children has long been used clinically to understand children’s experiences and inner feelings. More recently, children’s play has been examined quantitatively to understand differences due to varying backgrounds, family relationships, etc. Forty preschool children (21 girls and 19 boys) aged 27 to 71 months from families with histories of domestic violence were observed using a play interview, The MacArthur Story Stem Battery, to determine if severity of violence, frequency of visitation with their previously violent fathers, and mother-child relationship functioning impacted how parents were represented in play. Overall, girls represented their parents more positively regardless of other family circumstances. Boys, especially those who did not visit regularly with their fathers, had negative representations of their mothers. Severity of violence did not predict negative parental representations in the sample.     

Caregiver and Youth Agreement Regarding Youths’ Trauma Histories: Implications for Youths’ Functioning After Exposure to Trauma

Epidemiological research has demonstrated that youth are exposed to potentially traumatic events at high rates. Caregivers play an important role in youths’ successful recovery following exposures to potentially traumatic events. However, past research has documented poor caregiver–youth agreement regarding youths’ exposures to potentially traumatic events, indicating a potential lack of support for many youth exposed to such events. This study examined caregiver–youth discrepancies in the reports of youths’ lifetime exposures to potentially traumatic events, and the relationship between these reporting discrepancies and youths’ post-traumatic stress disorder (PTSD) symptoms, mood symptoms, and functional impairment following disclosures of sexual abuse. Participants included 114 caregiver–youth dyads participating in a family-based intervention at four Child Advocacy Centers in New York City. Standardized measures of trauma history, youth PTSD symptoms, youth mood symptoms, youth functional impairment, and caregiver PTSD symptoms were given in interview format to caregivers and youth at the time of intake into the intervention. The demographic composition of the youth sample was 86.8 % female, 13.2 % male, 32.5 % African American, 54.4 % Latino/a, 2.6 % Caucasian, 0.9 % Asian American, 8.8 % other race/ethnicity. Youth ranged in age from 7 to 16. Results demonstrated poor agreement between youth and caregivers regarding youths’ exposure to a range of potentially traumatic events and regarding youths’ PTSD symptoms, mood symptoms and functional impairment. Both caregiver–youth discrepancies regarding youths’ histories of exposures to potentially traumatic events and caregiver PTSD symptoms were significantly associated with youths’ self-reported symptoms and functional impairment. Only caregiver PTSD symptoms were related to caregivers’ reports of youths’ symptoms and functional impairment. Findings underscore the importance of family support and communication regarding exposures to potentially traumatic events and the detrimental associations of caregiver–youth disagreement about youths’ exposures to potentially traumatic events. Recommendations are provided for the assessment and treatment of families presenting in the aftermath of traumatic exposures.     

Genetic structure among 38 populations from the United States based on 11 U.S. core Y chromosome STRs

A DNA database consisting of the 11 Y chromosome short-tandem-repeat (Y-STR) recommended by the Scientific Working Group on DNA Analysis Methods is constructed for 2517 individuals from 38 populations in the United States. The population samples derive from five ethnic groups currently living in 10 states. A multidimensional scaling (MDS) plot places the populations into four discrete clusters (African Americans (AA), European Americans (EA), Hispanic Americans (HA), and Asian Americans (SA)) and one dispersed cluster of Native Americans. An analysis of molecular variance (AMOVA) indicates that a large proportion of the total genetic variance is partitioned among ethnic groups (24.8%), whereas only a small amount (1.5%) is found among-populations within ethnic groups. Separate AMOVA analyses within each ethnic group show that only the NA sample contains statistically significant among-population variation. Pair wise population differentiation tests do uncover heterogeneity among EA and among HA populations; however, this is due to only a single sample within each group. The analyses support the creation of AA, EA, HA, and Asian American databases in which samples from different geographic regions within the United States are pooled. We recommend that separate databases be constructed for different NA groups.     

Domestic violence research: what have we learned and where do we go from here?

Domestic violence has been an intense area of study in recent decades. Early studies helped with the understanding of the nature of perpetration, the cycle of violence, and the effect of family violence on children. More recently, studies have focused on beginning to evaluate domestic violence interventions and their effects on recidivism. This article acknowledges the importance of what we have learned about the prevalence and impact of domestic violence and explores the need for more focused effort to pinpoint interventions that are effective with perpetrators and victims. Methodological issues relevant to past intervention studies are also discussed and future research directions are outlined.
