Risk factors associated with the likelihood of being sexually victimized by a stranger or friend/acquaintance since being on the street was examined among 372 homeless and runaway youth. Young people were interviewed on the streets and in shelters by outreach workers using a systematic sampling strategy. Youth who engaged in more high-risk behaviors were expected to be at greater risk for sexual victimization by both known and unknown assailants. Results indicated that for females, running from home for the first time at an earlier age was associated with sexual victimization by both a stranger and friend/acquaintance. However, engaging in deviant subsistence strategies, survival sex, and grooming predicted being sexually victimized by a friend/acquaintance. For males, survival sex and grooming predicted stranger sexual victimization, whereas sexual orientation was associated with sexual victimization by a friend/acquaintance. Overall, 35% of the sample had been sexually victimized. 相似文献

The study of post-traumatic stress disorder (PTSD) in maltreated youth has received increased attention, though extensive comparisons to maltreated youth without PTSD and administrations of anxiety-based structured diagnostic interviews remain needed. We examined maltreated youth with or without PTSD using structured diagnostic interviews and standardized child self-report measures. We hypothesized that maltreated youth with PTSD, compared to their peers without PTSD, would experience significantly greater duration of abuse, diagnostic comorbidity, PTSD symptomatology, dysfunctional family environment, and avoidant coping styles. Results indicated that the group with PTSD did indeed experience significantly greater duration of abuse, diagnostic comorbidity, and PTSD symptomatology, though less so dysfunctional family environment or avoidant coping styles. The presence of a mood or anxiety disorder was highly predictive of PTSD in this sample. Results are discussed within the context of evolving etiological and maintenance models of PTSD in maltreated youth. 相似文献

Applying a forensic actuarial assessment (the Violence Risk Appraisal Guide) to nonforensic patients
The actuarial Violence Risk Appraisal Guide (VRAG) was developed for male offenders where it has shown excellent replicability in many new forensic samples using officially recorded outcomes. Clinicians also make decisions, however, about the risk of interpersonal violence posed by nonforensic psychiatric patients of both sexes. Could an actuarial risk assessment developed for male forensic populations be used for a broader clientele? We modified the VRAG to permit evaluation using data from the MacArthur Violence Risk Assessment Study that included nonforensic male and female patients and primarily self-reported violence. The modified VRAG yielded a large effect size in the prediction of dichotomous postdischarge severe violence over 20 and 50 weeks. Accuracy of VRAG predictions was unrelated to sex. The results provide evidence about the robustness of comprehensive actuarial risk assessments and the generality of the personal factors that underlie violent behavior. 相似文献

This study examines the prevalence of trauma, posttraumatic stress disorder (PTSD), and dissociative symptoms in adolescents. The sample consisted of 76 females and 76 males, between the ages of 12 and 18, referred to the Child Guidance Clinic of the Superior Court of the District of Columbia for a psychological evaluation. Two sets of analyses were conducted. One set included the entire sample; the second set excluded those individuals whose listed referral problem included only being a victim of abuse. Results of the study suggest a high prevalence of trauma in both genders; however, females had significantly higher rates than those reported in males. Similarly, female adolescents demonstrated significantly higher prevalence rates of PTSD symptoms compared with their male counterparts in the entire sample and showed a trend toward significance in the analysis of the subsample. There was a low prevalence of dissociative symptoms across both genders. 相似文献

Two factors potentially affect observers'attributions of responsibility to a rape survivor: how closely they identify with the survivor and how much they adhere to rape myths. To assess the impact of these factors, 157 female college students categorized by their sexual assault history and by their acceptance of rape myths, evaluated a sexual assault scenario. It was hypothesized that previously victimized participants would attribute less blame, and that those participants who self-identify as rape survivors would view the assault as rape more often than other participants. Neither hypothesis was supported. As expected, those who scored higher on the Rape Myths Acceptance Scale(RMAS) blamed the victim more and were less likely to believe rape had occurred. Only one subscale of the RMAS, Adversarial Sexual Beliefs, was consistently associated with participants'evaluation of the scenario, suggesting that this dimension may be especially important to understanding an observer's assessment of rape. 相似文献

Der Beitrag geht der Frage nach, wie national unterschiedliche politökonomische Institutionen die Leistungskraft entwickelter Marktwirtschaften beeinflussen und ob institutionelle Komplementaritäten in der Makroökonomie existieren. Der Ansatz der ?Spielarten des Kapitalismus“ behauptet, dass es diese Komplementaritäten gibt und sich die Länder entsprechend dem in den ökonomischen Sphären vorherrschenden Modus der Koordination in klare Gruppen unterscheiden lassen. In dem Artikel werden die Kernaussagen des Ansatzes einer Reihe von empirischen Tests unterzogen, die auf einer zusammenfassenden Analyse einer Reihe von Fallbeispielen beruht, Die empirischen Ergebnisse bestätigen die Annahmen in überzeugender Weise. Dieliberalen undkoordinierten Marktwirtschaften variieren systematisch entsprechend dem relativen Verhältnis zwischen marktförmiger und strategischer Koordination. Institutionelle Komplementaritäten finden sich in beiden Typen, und sie bringen gesamtwirtschaftliche Leistungszuwächse hervor. Abschließend werden die Muster des institutionellen Wandels in den entwickelten politischen Ökonomien analysiert und einige politische Implikationen der Befunde diskutiert. 相似文献

This paper proceeds with the premise that individual lives, societies and cultures in our globalizing era in general and in Western countries in particular are becoming increasingly fragile and vulnerable to fragmentation and atomization. This fragmentation, the paper argues, is embedded in a complex interplay between a variety of factors, including the forces unleashed by late modernity and globalization and the increasing diversification of societies across the globe. This is followed by a critique of the existing models of societal integration, including nationalism, multiculturalism, civil society and communitarianism. In the concluding part of the paper, multicommunitarianism is proposed as an alternative to the existing models of societal and national integration, aimed at healing the rupture caused by the processes of modernization and globalization and at restoring the balance and harmony between the individual and society. 相似文献
