This review examines the psychological impact of adult sexual assault through an ecological theoretical perspective to understand how factors at multiple levels of the social ecology contribute to post-assault sequelae. Using Bronfenbrenner's (1979, 1986, 1995) ecological theory of human development, we examine how individual-level factors (e.g., sociodemographics, biological/genetic factors), assault characteristics (e.g., victim-offender relationship, injury, alcohol use), microsystem factors (e.g., informal support from family and friends), meso/ exosystem factors (e.g., contact with the legal, medical, and mental health systems, and rape crisis centers), macrosystem factors (e.g., societal rape myth acceptance), and chronosystem factors (e.g., sexual revictimization and history of other victimizations) affect adult sexual assault survivors' mental health outcomes (e.g., post-traumatic stress disorder, depression, suicidality, and substance use). Self-blame is conceptualized as meta-construct that stems from all levels of this ecological model. Implications for curbing and/or preventing the negative mental health effects of sexual assault are discussed.

Sexual assault (SA) is a common and deleterious form of trauma. Over 40 years of research on its impact has suggested that SA has particularly severe effects on a variety of forms of psychopathology, and has highlighted unique aspects of SA as a form of trauma that contribute to these outcomes. The goal of this meta-analytic review was to synthesize the empirical literature from 1970–2014 (reflecting 497 effect sizes) to understand the degree to which (a) SA confers general risk for psychological dysfunction rather than specific risk for posttraumatic stress, and (b) differences in studies and samples account for variation in observed effects. Results indicate that people who have been sexually assaulted report significantly worse psychopathology than unassaulted comparisons (average Hedges’ g=0.61). SA was associated with increased risk for all forms of psychopathology assessed, and stronger associations were observed for posttraumatic stress and suicidality. Effects endured across differences in sample demographics. Broader SA operationalizations (e.g., including incapacitated, coerced, or nonpenetrative SA) were not associated with differences in effects, although including attempted SA in operationalizations resulted in lower effects. Larger effects were observed in samples with more assaults involving stranger perpetrators, weapons, or physical injury. In the context of the broader literature, our findings provide evidence that experiencing SA is major risk factor for multiple forms of psychological dysfunction across populations and assault types.

Sexual assault (SA) is a common form of trauma that is associated with numerous deleterious outcomes. Understanding the relative prevalence of psychiatric diagnoses in people who have been sexually assaulted versus people who have not been assaulted could help to prioritize assessment and intervention efforts, but there has been no quantitative review of this topic. A search of PsychINFO, ProQuest Digital Dissertations and Theses, and Academic Search Premier for articles dated between 1970 and 2014 was conducted, and unpublished data were obtained. Eligible studies used diagnostic interviews to assess Diagnostic and Statistical Manual of Mental Disorders diagnoses in both individuals experiencing adolescent/adult and/or lifetime SA and unassaulted individuals. The search yielded 171 eligible effects from 39 studies representing 88,539 participants. Meta-regression was used to aggregate the prevalence of psychiatric diagnoses in sexually assaulted and unassaulted samples as well as calculate odds ratios reflecting the difference between these prevalence estimates. Results indicated that most disorders were more prevalent in survivors of SA, and depressive disorders and posttraumatic stress disorder (PTSD) were especially prevalent. Disorder-specific differences in odds ratios were observed as a function of sample type, type of comparison group, and time frame of SA. Service providers should be prepared to address depressive disorders and PTSD in survivors of SA, and interventions that prevent the development of these disorders are especially needed.

Sexual minority women (SMW) are at high risk of trauma exposure and, subsequently, the development of posttraumatic stress disorder (PTSD). The authors extended a theoretical model explaining the higher risk of mental disorders in minority populations to the maintenance and exacerbation of PTSD symptoms among young adult SMW specifically. This study used observational longitudinal data from a sample of 348 trauma-exposed 18- to 25-year-old individuals assigned female sex at birth who identified as either bisexual (60.1%) or lesbian (39.9%) and met screening criteria for PTSD. Participants identified as White (82.8%), Hispanic/Latina (12.4%), American Indian/Alaska Native (13.5%), Black/African American (13.8%), and/or Asian/Asian American (4.9%). The authors investigated whether distal stressors (i.e., criterion A traumatic events, daily experiences of heterosexism) produced proximal stressors (i.e., trauma-related cognitions, internalized heterosexism) that maintained or exacerbated PTSD symptoms. Findings indicated that daily heterosexism longitudinally predicted trauma-related cognitions (i.e., cognitions related to the self, world, and self-blame). Internalized heterosexism and cognitions about the self longitudinally predicted PTSD symptom severity. In addition, a significant indirect effect was identified between daily heterosexism and PTSD symptoms via self-related posttraumatic cognitions. These findings suggest that exposure to minority-specific distal stressors appears to promote nonminority-specific cognitive processes that, in turn, may maintain or exacerbate PTSD among young adult SMW exposed to trauma. Clinicians should consider addressing daily heterosexism in young adult SMW presenting with PTSD and evaluate how these experiences might promote clients' global, negative views regarding themselves.

Secondary traumatic stress (STS) is an issue of significant concern among providers who work with survivors of sexual assault. Although STS has been studied in relation to individual-level characteristics of a variety of types of trauma responders, less research has focused specifically on rape crisis centers as environments that might convey risk or protection from STS, and no research to knowledge has modeled setting-level variation in correlates of STS. The current study uses a sample of 164 staff members representing 40 rape crisis centers across a single Midwestern state to investigate the staff member-and agency-level correlates of STS. Results suggest that correlates exist at both levels of analysis. Younger age and greater severity of sexual assault history were statistically significant individual-level predictors of increased STS. Greater frequency of supervision was more strongly related to secondary stress for non-advocates than for advocates. At the setting level, lower levels of supervision and higher client loads agency-wide accounted for unique variance in staff members' STS. These findings suggest that characteristics of both providers and their settings are important to consider when understanding their STS.

Posttraumatic stress disorder (PTSD) and substance use disorders (SUDs) commonly co-occur, and there is some evidence to suggest that PTSD symptom clusters are differentially related to various substances of abuse. However, few studies to date have compared PTSD symptom patterns across people with different types of SUDs, and fewer still have accounted for the presence of comorbidity across types of SUDs in understanding symptom patterns. Thus, in the current study, we use a treatment-seeking sample of people with elevated symptoms of PTSD and problem alcohol use to explore differential associations between past-year SUDs with active use and PTSD symptoms, while accounting for the presence of multiple SUDs. When comparing alcohol and drug use disorders, avoidance symptoms were elevated in those with alcohol use disorder, and hyperarousal symptoms were elevated in those who had a drug use disorder. In the subsample with alcohol use disorder, hyperarousal symptoms were elevated in people with co-occurring cocaine use disorders and numbing symptoms were elevated in people with co-occurring sedative/hypnotic/anxiolytic use disorder. These findings provide evidence for different symptom cluster patterns between PTSD and various types of SUDs and highlight the importance of examining the functional relationship between specific substances of abuse when understanding the interplay between PTSD and SUDs.

Most survivors of sexual assault disclose their experiences within their social networks, and these disclosure decisions can have important implications for their entry into formal systems and well-being, but no research has directly examined these networks as a strategy to understand disclosure decisions. Using a mixed-method approach that combined survey data, social network analysis, and interview data, we investigate whom, among potential informal responders in the social networks of college students who have experienced sexual assault, survivors contact regarding their assault, and how survivors narrate the role of networks in their decisions about whom to contact. Quantitative results suggest that characteristics of survivors, their social networks, and members of these networks are associated with disclosure decisions. Using data from social network analysis, we identified that survivors tended to disclose to a smaller proportion of their network when many network members had relationships with each other or when the network had more subgroups. Our qualitative analysis helps to contextualize these findings.
