Treatment-Related Reductions in Disability Are Associated with Reductions in Perceived Injustice Following Treatment of Whiplash Injury

Emerging evidence suggests that perceived injustice is a risk factor for poor recovery outcomes in individuals with whiplash injuries. The present study examined the relative contributions of treatment-related reductions in pain severity, depressive symptoms, and disability in the prediction of reductions in perceived injustice in individuals with whiplash injury. The study sample consisted of 71 individuals (43 women and 28 men) who sustained whiplash injuries in motor vehicle accidents and who were enrolled in a treatment program designed to promote functional recovery following whiplash injury. For the purposes of this study, only individuals who scored above the risk threshold on a measure of perceived injustice were included in the study sample. Participants completed measures of pain severity, disability, depressive symptomatology, and perceived injustice prior to treatment and after treatment. Change scores were computed for study variables. The results revealed that reductions in pain severity and disability were correlated with reductions in perceived injustice. Regression analyses revealed that only reductions in disability contributed significant unique variance to the prediction of reductions in perceived injustice. Clinical and theoretical implications of the present findings are discussed.

Alternatives to abstinence: the practice of (un)safe sex in prison

Correctional rules and regulations requiring sexual abstinence for prison inmates, coupled with unsupported beliefs about the risks of condom provision, keep most inmates in a dangerous muddle of criminalized sexual expression, covert efforts at erroneous myth-based safe sex practices, and high risk of sexual disease contraction and transmission. With the vast majority of inmates eventually released to re-enter communities across the US, these health concerns are not quarantined to the correctional environment, but rather contribute to what has been described as the hidden epidemic in public health . Using inmate voice from a large-scale national examination of inmate sexual behavior, the current study explores inmates’ attempts at ‘safe sex’ in an environment where sexual behavior, though prohibited, frequently occurs, and where no sex is the only accepted form of ‘safe’ sex. Inmates identify many approaches to safe sexual practice including barrier protection, partner selection, and risk reduction strategies. Unfortunately, many improvised, though innovative, inmate protection strategies reflect a very rudimentary understanding of safe sex for the purpose of reducing disease transmission and contraction, frequently exacerbating these risks. Policy implications include widespread condom provision and expanded inmate education and programming around sexual health and disease prevention.     

Child–Parent Violence: An Empirical Analysis of Offender, Victim, and Event Characteristics in a National Sample of Reported Incidents

Child–parent violence (CPV) is arguably the most under-researched form of family violence, despite an extremely high rate of occurrence and increasing prevalence. Prior research has been plagued by shortcomings including, but not limited to, a reliance on small clinical samples, age parameter restrictions, antiquated data, undefined parental relationships, and conflicting findings across studies. The current research examined a large cross-national sample of reported offenders (n = 17,957), collected as part of the 2002 National Incident Based Reporting System (NIBRS). Extrapolated from past literature, victim and offender demographics and incident characteristics are analyzed using chi-square tests and logistic regression to establish baseline findings from a more comprehensive sample of data than previously existed. Aggregate results suggest, in part, that white biological mothers older than 40 years of age are most likely to be victimized by their male children 14–17 years of age. Further, a majority of assaults involve personal weapons and tend to result in minor injury or no injury with very few offenders under the influence of alcohol or drugs. This work both corroborates and contrasts past finding of CPV research providing new insights into this complex crime and the baseline data needed to inform theory and test hypotheses.

Examining 19 years of officially reported child abduction incidents (1995–2013): employing a four category typology of abduction

Child abduction has generated extensive media attention due to deep-seated fear elicited by infamous incidents. Perceptions of an abduction epidemic during the 1970s and 80s entrenched a perception of ‘stranger danger’. Limited research on child abduction overemphasizes stranger abductions, which account for fewer than half of all abductions. As a result, less is known about the victim/abductor relationship across other abduction types. Prior work has emphasized simplistic stranger vs. family dichotomies, and similar trichotomies. This study, drawing on officially reported child abductions employing NIBRS datasets (N = 29,293), emphasizes differences across abductors/victims in a four category relationship-based typology, including a newer category – ‘intimate partner abductions’. Findings contribute baseline knowledge about child abductions by countering misplaced media driven fears and placing empirical findings in a more accurate context. Findings also reveal that intimate partner abductions have a unique victim/offender/incident profile and are the most serious and most consequential to adolescent female victims.     

A decade of child-initiated family violence: comparative analysis of child--parent violence and parricide examining offender, victim, and event characteristics in a national sample of reported incidents, 1995-2005

This article examines 11 years (1995-2005) of National Incident Based Reporting System data comparing victim, offender, and incident characteristics for two types of child-initiated family violence: child-parent violence (CPV) and parricide. The objective is to better understand the victim-offender relationship for CPV and parricide and to highlight distinguishing features between the two offenses. This work extends the research and addresses shortcomings in the extant literature. Data analysis consists of chi-square tests and logistic regression. Findings suggest that CPV and parricide are distinct and unique crimes. In short, parricide offenders and victims are both older than CPV offenders and victims, with CPV offenders more likely to be female, more likely to be African American, and less likely to use a weapon than parricide offenders. The study calls for future research and exploration of preliminary support for a family violence escalation hypothesis.
