Violent backgrounds of economically disadvantaged youth: Risk factors for perpetrating violence?

Adolescent Job Corps residents (n=474) reported the violence they had experienced, witnessed, and perpetrated with regards to parents, siblings, friends, and strangers. Results indicated that there was a high prevalence of all types of violence in this atrisk adolescent sample. Moreover, the majority of adolescents who reported violent experiences indicated threat or use of a weapon was involved. Gender differences were obtained such that boys reported perpetrating more aggression against friends and strangers than girls. Girls reported witnessing more parental aggression than boys. No gender differences in parental victimization rates were obtained. Contrary to prediction, parental victimization did not significantly predict perpetration towards siblings, friends, or strangers for either gender. However, parental victimization did predict increased violence towards parents. Surprisingly, for females especially, witnessing parental violence reduced the likelihood of violence towards parents. These findings support the need to include conflict resolution skills as a component of Job Corps training.     

The Development of Posttraumatic Stress Disorder (PTSD) in a Sample of Child Witnesses to Mother Assault

This exploratory study examined the relationship between the development of posttraumatic stress disorder (PTSD) and a number of coping variables in child witnesses to mother assault. The sample consisted of 84 children (mean age 11 years) who had been referred from shelters for battered women and child welfare agencies. Comparisons of those who met PTSD criteria (n = 47) and those who did not meet PTSD criteria (n = 37) found significant differences on variables of age, duration, and frequency of witnessing children. Child self-report instruments indicated that the PTSD group differed significantly from the non-PTSD group on the basis of assault anxiety, depression, dissociation, anger, and negative attributions. Hierarchical multiple regression analysis indicated that factors related to negative attributions and assault variables each contributed significantly to explaining 71% of the variance of PTSD symptoms, after the variables of age and sex were controlled. Discriminant function analysis correctly classified 84.3% of the respondents. The relevance of PTSD to child witnesses is considered, along with study limitations.     

The Relation of Parenting Styles and Inconsistencies to Adaptive Functioning for Children in Conflictual and Violent Families

Research of parenting in conflictual and violent families suggests that battered mothers (i.e., those experiencing verbal and/or physical abuse by their partner) may not parent very differently from demographically similar nonbattered mothers. However, battered mothers do report being less consistent in their discipline. In the present study, 104 mothers and their children from community nonviolent and violent families and shelter violent and violent abusive families participated in interviews to obtain information about child functioning and authoritative, authoritarian, and permissive parental practices. It was the case that authoritative practices were associated with more positive child functioning and that parental inconsistency, defined in terms of endorsing conflictual parenting practices, was associated with poorer child outcome. Groups of mothers were identified that fit different patterns of parenting practices, and these patterns were differentially related to children's functioning.     

Introduction of a standardized "paternity index" for the statistical evaluation of blood group findings in paternity testing

The introduction of a standardized paternity index (PI) for the statistical evaluation of blood group findings in cases of disputed paternity is proposed and explained. By using the PI $\text{X}\text{Y}$ as parameter, it is not necessary to give the information of the probability of paternity in percent. The PI includes the full information of the blood group findings. In addition to that, by using the suggested standardization based on the probabilities of error according to Schulte Mönting and Walter the test volume is also taken into account. The interpretation of the mathematical result is given by verbal predicates, the limitations of which are orientated by the verbal predicates for the probabilities of error according to Schulte Mönting and Walter, published by us elsewhere. Besides the essential fact that the test volume is taken into account, the most important advantage of this procedure is that the mathematical result is involved in the court decision only by the PI (which is free of any valuation) and its verbal predicate and not by sometimes relatively high percentages, which may be misunderstood by laymen.     

A comprehensive 5-year evaluation of project 12-ways: An ecobehavioral program for treating and preventing child abuse and neglect

Evaluations of services designed to ameliorate the problems associated with child abuse and/or neglect (CAN) are relatively rare. The present investigation examines the impact of ecobehavioral services provided to families with extensive histories of CAN and examines the demographics of two groups of families. Project 12-Ways provides in-home ecobehavioral treatment to families referred by the state protective service agency. Impact data were collected and compared from families served by Project 12-Ways and families served by the stale protective service agency and other community programs. These data focused on the rates of CAN, placement of children outside of the parental home, and permanent termination of parental rights. Comparisons were made on pretreatment, treatment, and post-treatment rates. It was determined that both samples experienced significant decrements in CAN. While the two samples were equivalent in rates of CAN, data were presented showing differences in severity and priority of CAN which suggest that ecobehavioral services can be successful in reducing CAN. Thus, a heuristic model is available for evaluating CAN, including the manner in which the data were collected, the range of independent variables included, and the considerable span of the families' lives covered in the evaluation. These results suggest some modification of the way in which follow-up data are collected and used to change policy and practice.     

A Descriptive Analysis of Same-Sex Relationship Violence for a Diverse Sample

This study contributed to the data about same-sex relationship violence with a large sample (n = 499) of ethnically diverse gay men, lesbians, and bisexual and transgendered people. Physical violence was reported in 9% of current and 32% of past relationships. One percent of participants had experienced forced sex in their current relationship. Nine percent reported this experience in past relationships. Emotional abuse was reported by 83% of the participants. Women reported higher frequencies than men for physical abuse, coercion, shame, threats, and use of children for control. Across types of abuse, ethnic differences emerged regarding physical abuse and coercion. Differences across age groups were found regarding coercion, shame, and use of children as tools. Higher income was correlated with increased threats, stalking, sexual, physical, and financial abuses. Preliminary patterns of same-sex relationship abuses were examined for bisexual and transgendered people.     

Examining the Behavior of a System: An Outcome Evaluation of a Coordinated Community Response to Domestic Violence

One goal of a coordinated community response (CCR) to domestic violence is to create an infrastructure that will facilitate systems-level, and ultimately societal-level change. This study evaluated whether a CCR implemented in two counties in Georgia would be effective at increasing criminal justice system sanctions for male domestic violence offenders (i.e., arrests, prosecutions, convictions, sentencing, and referrals to batterer intervention programs). Time series analyses revealed that, in both counties, there was a significant increase in arrests of male offenders; however, law enforcement agencies also arrested more women following the intervention. More men were sentenced to probation and to attend a batterer’s intervention program post-intervention in one county; in the second county, there was no change in these outcomes. Results highlight the importance of examining how a CCR may affect the behavior of criminal justice systems, especially in terms of the unintended consequences for women.     

Programs for Men who Perpetrate Domestic Violence: An Examination of the Issues Underlying the Effectiveness of Intervention Programs

This review paper seeks to explore some of the reasons why rehabilitation programs for male perpetrators of domestic violence appear to be less effective in reducing recidivism than programs for other offender groups. It is argued that while the model of systems response to domestic violence has predominated at the inter-agency level, further consideration might be given to way in which men’s intervention groups are both designed and delivered. It is concluded that the program logic of men’s domestic violence programs is rarely articulated leading to low levels of program integrity, and that one way to further improve program effectiveness is to incorporate some of the approaches evident in more general violence prevention programs and from what is know about good practice in general about offender rehabilitation.

The reliabilty and validity of a revised version of the How I Think Questionnaire for men who have intellectual disabilities

The aim of this study was to revise an existing measure of distorted cognitions, creating the How I Think Questionnaire – Intellectual Disabilities (HIT-IDs), and to investigate the reliability and validity of the revised questionnaire. To achieve our aims, we recruited 97 men with intellectual disabilities (IDs), with or without a history of engaging in criminal behaviour, and interviewed them on two occasions, inviting them to complete the HIT-IDs, along with measures of moral development and empathy. The results indicated that the internal consistency of the HIT-IDs was acceptable, and the test–retest reliability was good. The HIT-IDs discriminated well between offenders and non-offenders, and as expected, correlated positively with a measure of moral development and negatively with a measure of empathy. The HIT-IDs is a reliable and valid measure for use with men who have IDs.

The suitability of visual taphonomic methods for digital photographs: An experimental approach with pig carcasses in a tropical climate

In the context of increased scrutiny of the methods in forensic sciences, it is essential to ensure that the approaches used in forensic taphonomy to measure decomposition and estimate the postmortem interval are underpinned by robust evidence-based data. Digital photographs are an important source of documentation in forensic taphonomic investigations but the suitability of the current approaches for photographs, rather than real-time remains, is poorly studied which can undermine accurate forensic conclusions. The present study aimed to investigate the suitability of 2D colour digital photographs for evaluating decomposition of exposed human analogues (Sus scrofa domesticus) in a tropical savanna environment (Hawaii), using two published scoring methods; Megyesi et al., 2005 and Keough et al., 2017. It was found that there were significant differences between the real-time and photograph decomposition scores when the Megyesi et al. method was used. However, the Keough et al. method applied to photographs reflected real-time decomposition more closely and thus appears more suitable to evaluate pig decomposition from 2D photographs. The findings indicate that the type of scoring method used has a significant impact on the ability to accurately evaluate the decomposition of exposed pig carcasses from photographs. It was further identified that photographic taphonomic analysis can reach high inter-observer reproducibility. These novel findings are of significant importance for the forensic sciences as they highlight the potential for high quality photograph coverage to provide useful complementary information for the forensic taphonomic investigation. New recommendations to develop robust transparent approaches adapted to photographs in forensic taphonomy are suggested based on these findings.
