Optimism as a Mediator Between the Experience of Child Abuse,Other Traumatic Events,and Distress

In this study, we examined the role of dispositional optimism in mediating distress among students who experienced traumatic events, including child physical abuse, emotional abuse, and sexual abuse. Participants included 199 undergraduate and graduate students (aged 18–63 years) from a private university in Oregon. In this study, dispositional optimism partially mediated distress among individuals who had experienced child physical abuse and child emotional abuse; participants with higher levels of optimism had lower levels of distress. In addition, dispositional optimism fully mediated distress among individuals who had experienced traumatic events such as rape, assault, and fire; participants with higher levels of optimism had lower levels of distress. Contrary to prediction, the experience of child sexual abuse was not associated with distress. Clinical implications of these results are addressed.     

Development and validation of the Cozart DDS oral fluid collection device

The testing of oral fluid for drugs of abuse has increased significantly over recent years and is now commonplace in drug rehabilitation clinics, the workplace, prisons and custody suites. The global problem of identifying drugged drivers has also led to an increase in oral fluid testing at the roadside. The main requirements for the implementation of roadside drug testing are a rapid sample collection time, collection of a known sample volume and recovery of drugs from the collection device. We report here the development of the Cozart^® DDS oral fluid collector, an oral fluid collector that combines rapid and adequate sample collection with satisfactory drug recovery. Oral fluid was collected from drug users (n = 134) and drug-free individuals (n = 137), using the Cozart^® DDS oral fluid collector. The mean time for the completion of collection (full coloration of the sample presence indicator) was 34 s for drug-free individuals and 44 s for drug users. The average volume collected was 0.34 mL (n = 271). No chemical stimulant (to induce salivation) was used to achieve the collection times observed in either the drug-free or the drug-taking sample populations. Drugs were extracted from the collector using the Cozart^® DDS buffer and drug recovery was determined by Cozart^® enzyme immunoassays. The recovery studies showed that for amphetamine, Δ⁹THC, cocaine, methadone, methamphetamine, morphine and temazepam over 90% of the drug in the sample was eluted from the collector. The Cozart^® DDS oral fluid collector provides a reliable mechanism for the collection of oral fluid at the roadside that achieves the rapid collection times required.

Risk Factors Associated with the Chronicity of High Potential for Child Abuse and Neglect

The present 4-year follow-up study involves 56 mothers who were evaluated by social agencies as being abusive and neglectful or at high risk for child abuse and neglect. The aim of the study is to analyze the relationship between psychosocial risk factors (relating to the history and current situation of the mothers) that were present at the time the families were initially recruited and the fact that some of the mothers continue to show a high potential for child abuse and neglect (chronic abuse and neglect), whereas others were able to overcome the problem (transitory abuse and neglect). Results indicate that the following variables are particularly associated with situations involving chronic problems of abuse and neglect: initial level of severity of potential for abuse and neglect; dual-parent status; a large number of children at the time of intervention (3.13 times more risk of chronicity for large families); the fact that as a child the mother herself had been placed in a foster home (3.7 times more risk); that she had been sexually abused (3.5 times more risk); and that as an adolescent she had run away from home (3.02 times more risk). Our results indicate that mothers who have a combination of more than eight risk factors are four times more likely to be in the chronic group.

Childhood Sexual Abuse and HIV Risk Among Men Who Have Sex with Men: Initial Test of a Conceptual Model

Childhood sexual abuse has been associated with HIV transmission risk behavior in men who have sex with men. This study examined an adapted model that was originally developed to explain the relationship between childhood sexual abuse and HIV risk behavior among women in a sample of men who have sex with men. Men attending a large gay pride event (n=647) completed anonymous surveys that assessed demographic characteristics, childhood sexual abuse, symptoms of dissociation, trauma-related anxiety, borderline personality characteristics, hopelessness, substance use, and sexual risk behavior. A latent variable partial least squares analysis was conducted to test the interrelationships between childhood sexual abuse, exchanging sex for money or drugs, emotional disturbances, drug use, substance use in the context of sexual behavior, and sexual risk behavior. The model fit the data well and accounted for 10% of the total variance in sexual risk behavior. History of childhood sexual abuse predicted exchanging sex for money or drugs and this relationship was partly accounted for by active drug use. Substance use proximal to sexual behavior also emerged as a key factor in predicting sexual risk behavior. Findings from this study, therefore, indicate a direct association between history of child sexual abuse and high risk for HIV infection related to engaging in sex trade.     

Continuities in marital violence

Marital violence studies of clinical populations of battered women indicate that, over time, violence becomes an habitual strategy for resolving conflicts resulting in escalation in frequency and severity of violence. This study examines the issue of continuity of marital violence among a national probability sample of female victims and male offenders. Findings indicate that among the general population, approximately one-half of all marital violence is suspended over a three-year period. Predictors of marital violence continuity were also investigated in an exploratory way.     

Sex differences in the experience of child sexual victimization

This study analyzed 390 (303 girls and 87 boys) cases of child sexual abuse to understand sex differences in child sexual victimization. Analyses focused on three domains that have received considerable empirical attention: victims' relationships with the offender, type and extent of abuse, and disclosure. Findings largely replicated previous efforts that reported sex differences in terms of victims' relationships with offenders. Although results also replicated previous findings about sex differences in disclosure patterns, these sex differences were minor in comparison with similarities in the way most instances of abuse were eventually identified. In terms of type and extent of abuse, results were the opposite of previous findings: girls, not boys, were the victims of more physical injury, violent threats, and use of force; and girls, not boys, were more likely to have physically resisted abuse. Divergences in findings were interpreted in terms of memory biases and social forces operating differently on the sexes.     

Linking marital violence,mother-child/father-child aggression,and child behavior problems

Previous research indicates that observation of marital violence has a deleterious impact on children's adjustment. However, little is known about the mechanisms underlying this relationship. The present study examined the relationships between observation of marital violence, mother-child aggression, father-child aggression, and child behavior problems in a sample of 185 children (ages 7 to 13) and their mothers who were residing at battered women shelters. A significant positive association was found between amount of marital violence witnessed and father-child aggression. However, the correlation between the amount of marital violence witnessed and mother-child aggression was not significant. Hierarchical regression analyses revealed that both the amount of marital violence witnessed as well as mother-child aggression were significantly related to child behavior problems, even when controlling for the effects of child age, race, and father status (i.e., whether the mother's partner was the biological father or stepfather/cohabitee). Family violence variables were better predictors of girls' rather than boys' behavior problems, particularly externalizing behavior problem scores. The lack of significance between father-child aggression and child behavior problems, as well as the implications of the findings, are discussed.
