About

Mary Koss, PhD, is a Regents’ Professor in the Mel and Enid Zuckerman College of Public Health at the University of Arizona. She published the first national study of sexual assault among college students in 1987, which is the subject of I Never Called it Rape: The Ms. Report on Recognizing, Fighting and Surviving Date and Acquaintance Rape (2019). The story of this work is featured on National Public Radio’s This American Life, https://www.thisamericanlife.org/770/my-lying-eyes In 2022 she published a 30-year prevalence comparison in new national data that demonstrate sexual exploitation occurs even more frequently now than then. Especially salient were the percentage of rapes that involved victims incapacitated by alcohol. Her ongoing prevention work is funded by NIAAA and is a clinical trial of a sexual assault bystander prevention program focusing on staff of liquor serving establishments (Safer Bars). Koss led the 14-member team that has recently revised the Sexual Experiences Survey (SES-V, 2024) to measure sexual exploitation prevalence, which is explored in a 6-article special issue of The Journal of Sex Research published open access in July 2024. The SES-V materials are available on Open Science https://osf.io/hxpsk For a survey demonstration on mobile phone, click: https://uarizona.co1.qualtrics.com/jfe/form/SV_6A64XSPRlCReRTM (looks best if done from a phone). Koss was the principal investigator of the RESTORE Program; the first [and still only] restorative justice program for sex crimes among adults that was quantitatively and qualitatively evaluated and published in scientific peer review journals. With a colleague, she recently worked on a listening project to learn what survivor victims say they needed to help them recover, their experiences with justice, and their reactions to the restorative justice conferencing model. Recognizing the mismatch between victims perceived post-assault needs and what key informants envision as their service scope, she advocates for victim-centered, trauma informed resolution outside the criminal legal system as a component of a comprehensive menu of post-assault services (Chisolm & Koss, 2024, International Journal of Restorative Justice and 2024 Violence Against Women). An article illustrating how this vision could be accomplished within existing VAWA purpose areas recently appeared in Psychology of Violence. Her credentials document close to 200 peer review empirical publications and sustained consultations with national and international health organizations and governments. She has received honors from the American Psychological Association: the Award for Distinguished Contributions to Research in Public Policy (2000), Award for Distinguished Contributions to the International Advancement of Psychology (2017), the Carolyn Wood Sherif Award for Sustained Contributions to Psychology of Women (2020), and the Trailblazer Award (2022) from the Sexual Violence Research Initiative based in Johannesburg, South Africa.

The Psychological Consequences of Sexual Trauma

Hosted By:

VAWnet.org ,

Harrisburg, Pennsylvania, United States
The psychological consequences of sexual trauma among survivors have been widely studied, but research investigations continue, in part, because rates of violence against girls and women remain high. The National Violence Against Women Survey found that 18% of women reported experiencing a completed or attempted rape during their lifetime (Tjaden & Thoennes, 2000). More than half (54%) of the rape survivors that responded to the survey were younger than age 18 when they experienced their first attempted or completed rape. Ongoing research attention to mental health outcomes is also driven by evidence that survivors’ responses are largely complex and unique to each individual (Briere & Jordan, 2004). Some individuals experience severe symptoms or longterm distress, whereas others do not (e.g., Kendall-Tackett, Williams, & Finkelhor, 1993). The diversity in outcomes may be attributed to characteristics of the violent acts, environmental conditions, survivor attributes, and availability of social support and resources. Another contributing factor is the use of different methodologies across research investigations. Although some individuals may be resilient to the negative effects of sexual trauma, it does not minimize the observation that for other women sexual victimization is the most devastating event they will experience. This paper describes current research findings on the effects of childhood and adulthood sexual victimization on women’s mental health. Existing data on understudied communities and risk factors for mental health problems are also presented. Childhood and adulthood sexual violence are discussed separately because, contrary to public opinion, sexual violence against children is fairly common and is frequently associated with psychological distress that continues into adulthood. There is also evidence that the mental health effects of childhood sexual victimization might be different from those due to adulthood victimization (e.g., Coid et al., 2003). This document does not cover other health outcomes, such as chronic medical conditions and reproductive and maternal health problems, because those outcomes make up a distinct body of literature that requires a focused review in their own right. Having knowledge in this area is critical for all individuals working with survivors, including victim advocates, community health workers, and policy makers. First, it promotes continued empathy and support for survivors. Second, the knowledge may help diverse groups of service providers respond to current trends toward professionalization of the field of sexual violence. As state and federal funding for violence against women face budget cuts from year to year, organizations have had to move away from grassroots models to professional models (Patricia Yancey Martin, 2005). Professional models include the use of evaluation and analytic tools and other activities related to writing proposals and managing grants and contracts. This requires knowledge of the research literature and the language and conceptual models frequently used by scientists and professionals. This paper provides a review that will hopefully facilitate discussions of the psychological consequences of sexual victimization across different individuals and organizations that work with or for survivors.

Lessons Learned from Using GIS M apping for Community Violence Prevention Planning

Hosted By:

American Public Health Association (APHA) ,

District of Columbia, United States
Geographic Information Systems (GIS) mapping is a novel method for spatially visualizing data, and has been used in community health planning to assess health inequity issues such as life span, poverty, and access to healthy foods. In recent years, CDC has suggested that assessment the relationship between alcohol policies and police reports for interpersonal violence should be considered in community violence prevention planning. Particularly, it has been suggested that there may be a spatial relationship between density of liquor licenses (i.e., many liquor-serving establishments close together) and ‘hot spots’ of police reports for physical and sexual violence. Violence prevention specialists have been encouraged to use GIS mapping to assess spatial patterns of interpersonal violence in order to identify areas in which to target prevention efforts. Although GIS mapping is an exceptional tool for presenting data, the resources needed to use this method using public data is rarely discussed. In this presentation, we will discuss a recent study undertaken by researchers and students at The University of Arizona to map the relationship between liquor licenses and police reports of violent crime in four major cities in Arizona. Data on liquor licenses was obtained from the state liquor licensing department, and crime datasets were obtained from local police departments. The results showed hot spots of police reports for violence around major university campuses, which typically had high densities of alcohol-serving establishments within a one-mile radius. In this presentation, we will focus on general lessons learned from the GIS process, which was a new method for the research team, that can be applied to using this approach to measure health equity/inequity. Specifically, we will discuss successes and challenges in planning for GIS mapping on a limited budget, obtaining and cleaning data, software and personnel skills needed to conduct GIS mapping, and tips for making maps useful for policy and practice. Examples of how the GIS maps from this study were utilized in policy and practice recommendations in Arizona will also be discussed.
