Few studies have explored the direct impact of behavioral parent training programs on child maltreatment behaviors among marginalized, at-risk fathers. This feasibility study examined SafeCare® Dad to Kids (Dad2K), an augmented version of the evidence-based child maltreatment prevention program SafeCare, to determine the acceptability and initial efficacy of the program for improving father parenting skills and reducing maltreatment risk. Ninety-nine fathers were enrolled in the study and randomized to the SafeCare Dad2K Intervention (n?=?51) or comparison (n?=?48). Intervention fathers participated in 6 home visiting sessions and comparison fathers received parenting materials via mail. All fathers participating in the study completed a baseline and 8-week assessment (post-intervention) of maltreatment behaviors. In addition, intervention fathers completed feasibility and parenting skill measures. A significant main effect emerged indicating decreases for both groups in psychologically aggressive behaviors. No significant group by time findings emerged for child maltreatment behaviors. Father intervention completers endorsed high satisfaction ratings for the program and demonstrated significant improvements in targeted father-child interaction skills. Based on the high rates of acceptability and initial improvement in positive parenting skills, findings demonstrate the feasibility for involving at-risk fathers in behavioral parent training programs targeting child maltreatment prevention.  相似文献

The identification of potential child maltreatment using reliable and valid screening instruments is of particular importance in high risk populations. The current study investigates the psychometric properties of the Brief Child Abuse Potential (BCAP) Inventory in mothers enrolled in opioid substitution therapy. The BCAP Risk Abuse scale had strong internal reliability. Comparisons between valid and invalid protocols (≥ 4 on the Lie scale, > 1 Random Responding) failed to find systematic differences across most variables although those with a faking good profile had significantly lower scores on psychological well being. A six-factor solution was obtained and was conceptually strong. Subsequent analyses suggested Rigidity may be an independent subscale that needs further investigation. These results add further evidence for the potential utility of the BCAP as a measure of child abuse potential. Replication studies are needed to ascertain whether the subscales derived have convergent and predictive utility.  相似文献

The present experiment examined how the seating position of an interpreter during investigative interviews affects information elicitation and cues to deceit. A total of 60 native English speakers were interviewed in English and 200 non-native English speakers were interviewed in English (a non-native language) or through an interpreter who either sat next to the interviewer, behind the interviewee or interpreted via the telephone. Interviewees either lied or told the truth about a mock security meeting they watched. Interviewees who spoke in their native language provided more detail than interviewees who spoke in their native language through an interpreter or in a non-native language (English) without an interpreter. The latter groups did not differ. Additionally, the amount of detail differentiated truth tellers from liars in all conditions and interviewees found the presence of an interpreter to be a largely positive experience. The interpreter’s seating position had no effect on the findings.  相似文献

This study examined the longitudinal association between contextual stress and health risk behaviors and the role of protective factors in a community epidemiologically-defined sample of urban African American adolescents (N = 500; 46.4% female). Structural equation modeling was used to create a latent variable measuring contextual stress (community violence, neighborhood disorder, and experiences with racial discrimination). Contextual stress in 8th grade was associated with aggressive behavior and substance use 2 years later for boys. For girls, contextual stress predicted later substance use, but not aggressive behavior. High academic competence and self-worth reduced the impact of contextual stress on substance use for boys. Implications for intervention and directions for future research on health risk behaviors among African American adolescents are discussed.  相似文献

Abstract:  With <100 pg of template DNA, routine short tandem repeat (STR) analysis often fails, resulting in no or partial profiles and increased stochastic effects. To overcome this, some have investigated preamplification methods that include the addition of proofreading enzymes to the PCR cocktail. This project sought to determine whether adding proofreading polymerases directly in the STR amplification mixture would improve the reaction when little template DNA is available. Platinum Taq High Fidelity and GeneAmp High Fidelity were tested in Profiler Plus? STR reactions alone and in combination with AmpliTaq® Gold. All reactions included the additional step of a post‐PCR purification step. With both pristine low template DNA and casework samples, the addition of these polymerases resulted in comparable or no improvement in the STR amplification signal. Further, stochastic effects and artifacts were observed equally across all enzyme conditions. Based on these studies, the addition of these proofreading enzymes to a multiplex STR amplification is not recommended for low template DNA work.  相似文献

Intimate partner violence continues to be prevalent, resulting in negative consequences for the individuals involved and for society as a whole. Perceptions of safety in relationships where intimate partner violence is present is an understudied topic in the literature. The Safety Assessment of Future Events Scale (SAFE) was developed to assess respondents’ perceptions of safety in their intimate relationship. The purpose of this study was to examine whether group differences existed on respondents’ SAFE scores. 428 participants from community and clinic samples completed the SAFE and other measures contained in a southwest university’s marriage and family therapy clinic intake packet. ANCOVA was used to control for gender and setting in determining if group differences existed on the SAFE based on measures assessing interpersonal violence, relational adjustment, intrapersonal symptoms, and PTSD symptoms. Results indicated group differences based on gender, interpersonal violence victimization, and relational adjustment.  相似文献

Should counselors with interpersonal trauma histories work with similarly traumatized clients? How does the work affect them? Current research is inconsistent. This study examines 101 sexual assault and domestic violence counselors' recalled motivations for trauma work, their reported subjective personal changes, and their secondary and vicarious trauma symptoms and burnout. Counselors motivated by interpersonal trauma report both more symptoms and positive changes (including dealing with their own trauma). Those seeking personal meaning report becoming more hypervigilant and self-isolating. Those saying they learned from clients rate symptoms lower, suggesting stress inoculation. Supervisors of trauma counselors should facilitate learning from clients separately from processing the counselor's trauma.  相似文献

The article focuses on the legal implications of the constructionof the International Court of Justice (ICJ or the Court) ofthe duty to punish genocide under Article VI of the Conventionon the Prevention and Punishment of the Crime of Genocide inthe Bosnia and Herzegovina v. Serbia and Montenegro judgment.It posits that the Court's discussion of the duty to punishis satisfying in terms of what it says and less satisfying interms of what it is silent about. It is satisfying in the sensethat the Court's construction of the duty to cooperate withinternational tribunals prosecuting genocide as including aduty of extradition, seems to extend beyond the plain languageof the Convention and indeed beyond the parties’ originalintent. It is not fully satisfying because the duty to prosecuteremains quite limited. It is further argued that the obligationto punish genocide as established in Article I and the obligationto prosecute genocide as established in Article VI should beunderstood as two distinct obligations. Article VI merely setsthe institutional arrangements for prosecution. Other normativesources support the conclusion that a general duty to prosecuteperpetrators of genocide or extradite them for prosecution elsewhereapplies even in those cases where the offence was not committedin the territory of a contracting state or when the offenderis prosecuted by an international court that has jurisdictionover the state where the alleged perpetrator is found.  相似文献
