Correlates of sexual abuse in a sample of adolescent girls admitted to psychiatric inpatient care

Forcible Rape and Adolescent Friendship Networks

Studies have found that sexual victimization can adversely affect an adolescent's psychological well-being, physical health, and behavior. Little is known, however, about how friendships are influenced by such victimization. Drawing on research on sexual violence and the salience of peers among adolescents, the current study extends prior work by examining the effects of forcible rape on adolescent social networks. Using a subsample of females from the National Longitudinal Study of Adolescent to Adult Health (N = 4,386), the study employs multivariate regression analyses to estimate the effects of youth forcible rape on the popularity, centrality, and density of adolescent friendship networks and to determine whether depression and attachment to others (e.g., to friends and to school) mediate these effects. The analyses indicated that forcible rape was associated with a decrease in the popularity and centrality of females within their friendship networks; however, no effect on the density of these networks was identified. In addition, forcible rape effects on popularity and centrality were partially mediated by depression and social attachments. The results suggest that forcible rape may adversely affect adolescent females' levels of popularity and centrality within their friendship networks. Combined with prior research, the results indicate that the harmful effects of rape have the potential to extend across diverse domains, including social relationships. This possibility suggests that services and assistance to female adolescents may be useful in navigating these relationships after victimization. It suggests, too, that potential benefits that may arise from interventions that educate adolescents-victims and nonvictims alike-about the challenges that victims of sexual violence experience.

Effects of perpetrator identity on suicidality and nonsuicidal self-injury in sexually victimized female adolescents

PURPOSE

Child sexual abuse and sexual dating violence victimization are common problems that are known to have long-term negative consequences. This study aimed to compare the sociodemographic, abuse-related, and clinical features of female adolescents who were sexually abused by different perpetrators, and identify the factors associated with suicidality and nonsuicidal self-injury (NSSI) in these cases.

PATIENTS AND METHODS

Data of 254 sexually abused female adolescents between the ages of 12-18 years were evaluated. The cases were classified into three groups, namely "sexual dating violence", "incest", and "other child sexual abuse", according to the identity of the perpetrator. The three groups were compared in terms of sociodemographic, abuse-related, and clinical features.

RESULTS

Major depressive disorder was the most common psychiatric diagnosis, which was present in 44.9% of the cases. Among all victims, 25.6% had attempted suicide, 52.0% had suicidal ideation, and 23.6% had NSSI during the postabuse period. A logistic regression analysis revealed that attempted suicide was predicted by dating violence victimization (adjusted odds ratio [AOR] =3.053; 95% confidence interval [CI] =1.473, 6.330) and depression (AOR =2.238; 95% CI =1.226, 4.086). Dating violence victimization was also the strongest predictor of subsequent suicidal ideation (AOR =3.500; 95% CI =1.817, 6.741). In addition, revictimization was determined to be an important risk factor for both suicidal ideation (AOR =2.897; 95% CI =1.276, 6.574) and NSSI (AOR =3.847; 95% CI =1.899, 7.794).

CONCLUSION

Perpetrator identity and revictimization are associated with negative mental health outcomes in sexually victimized female adolescents. Increased risk of suicidality and NSSI should be borne in mind while assessing cases with dating violence and revictimization histories, in particular.

Inflammation and neuronal plasticity: a link between childhood trauma and depression pathogenesis

During the past two decades, there has been increasing interest in understanding and characterizing the role of inflammation in major depressive disorder (MDD). Indeed, several are the evidences linking alterations in the inflammatory system to Major Depression, including the presence of elevated levels of pro-inflammatory cytokines, together with other mediators of inflammation. However, it is still not clear whether inflammation represents a cause or whether other factors related to depression result in these immunological effects. Regardless, exposure to early life stressful events, which represent a vulnerability factor for the development of psychiatric disorders, act through the modulation of inflammatory responses, but also of neuroplastic mechanisms over the entire life span. Indeed, early life stressful events can cause, possibly through epigenetic changes that persist over time, up to adulthood. Such alterations may concur to increase the vulnerability to develop psychopathologies. In this review we will discuss the role of inflammation and neuronal plasticity as relevant processes underlying depression development. Moreover, we will discuss the role of epigenetics in inducing alterations in inflammation-immune systems as well as dysfunction in neuronal plasticity, thus contributing to the long-lasting negative effects of stressful life events early in life and the consequent enhanced risk for depression. Finally we will provide an overview on the potential role of inflammatory system to aid diagnosis, predict treatment response, enhance treatment matching, and prevent the onset or relapse of Major Depression.
