Measure of Personal Network Size Using the Known Population Method: A Methodological Guide.

The network scale-up method (NSUM) has shown promise in measuring the prevalence of hidden public health problems and at-risk populations. The technique involves asking survey respondents how many people they know with the health problem or characteristic of interest and extrapolating this information to the population level. An important component of the NSUM estimate is the size of each respondent's network, which is determined by asking respondents about the number of people they know who belong to populations of known size. There is little systematic discussion, however, to guide selection of these questions. Furthermore, many of the most commonly used known population questions are appropriate only in countries with a robust data infrastructure. Here, we draw from the NSUM literature to present a set of best practices in the selection of NSUM known population questions. Throughout, we address the unique situations that many researchers face in collecting prevalence data in the developing world, where innovative prevalence estimation techniques, such as NSUM, are most needed.

Sexual harassment training and men's motivation to work with women.

With the #MeToo movement generating renewed public attention to the problem of sexual misconduct, it is an important time to assess how sexual harassment training affects men's motivation to work with women. We conducted an experiment in which we exposed undergraduate men to sexual harassment policy training and then assessed their motivation to work with a female partner on a decision-making task. We employed a 2 × 2 design in which participants were randomly assigned to a policy condition (sexual harassment policy or control) and a team role (leader or subordinate). We found that policy training did not affect whether participants chose a female or male partner. However, we found that policy training led male participants to rate female partners as more dissimilar to them and that leadership status moderated the effect of policies on men's expressed anxiety about working with a female partner. Findings have implications for reducing sexual harassment and gender inequality.

Shameful "Victims" and Angry "Survivors": Emotion, Mental Health, and Labeling Sexual Assault.

Decades of research demonstrate that women frequently avoid the label "rape" when reflecting on nonconsensual sexual experiences. The current study focuses on self-labels to further understand the relationship between assault characteristics, emotion, mental health, and women's labeling of sexual assault. We argue that emotions produced by various assault characteristics are important mechanisms for understanding self-labeling after a sexual assault. We draw from research on rape scripts and cultural discourses of victimhood, survivorhood, and emotion to examine labeling "rape" and self-labeling as a "victim" or "survivor" in an online survey of 138 undergraduate women at a southeastern university. Using a series of ordinal logistic regressions in which labels are regressed on emotions and measures of mental health, we find that the "victim" label is associated with shame and post-traumatic stress, while the "survivor" label is associated with anger and less depression.

What Will People Think? How College Students Evaluate Bystander Intervention Behavior.

Many colleges utilize bystander intervention programs to address gender-based violence. The goal of these programs is to help students overcome barriers to intervention, including evaluation inhibition, which occurs when bystanders expect to be viewed negatively for intervening. We have limited information, though, on how college students evaluate bystanders who intervene. Specifically, we do not know whether evaluations of bystanders who engage in different levels of intervention vary across situations or how men and women who intervene similarly are evaluated. Without this information, it is difficult to design prevention programs that help bystanders overcome evaluation inhibition. To gather this information, we conducted a vignette experiment with college student participants (n = 82). We specifically examined how students evaluated the reasonableness of male and female bystanders who engaged in different behaviors (direct intervention and threatening to tell an authority, direct intervention only, indirect intervention, doing nothing) across four situations (assault at a party, workplace harassment, harassment by a teaching assistant, and intimate partner violence). Analyses of variance found that there was situational variability in how the bystander is evaluated for different intervention tactics, though bystanders who did nothing were always evaluated the most negatively. Bystander's gender, however, did not affect evaluations, suggesting that intervention expectations for men and women are similar. These results indicate that while there is an underlying norm supportive of intervention behavior, situational characteristics influence whether college students think it is reasonable to call authorities, confront the perpetrator, or engage in indirect intervention. The central implication of this study is that bystander intervention training should provide opportunities for students to practice intervention behaviors across a wide variety of situations of gender-based violence in order build up their store of intervention tactics, thus increasing their ability to overcome evaluation inhibition.

Violence Increases Psychological Distress Among Women Trafficking Survivors in Ghana.

Human trafficking is a crime that is often shaped by violence, particularly for women who are trafficked. Additionally, trafficking survivors often report severe psychological distress, though research on the causes of this psychological distress is lacking, as there is little longitudinal data available on trafficking survivors. Informed by past literature on the links between violence and mental health among other traumatized groups of women, we investigate how experiences of violence influence posttraumatic stress, depression, and suicide ideation among a unique longitudinal sample of 116 labor-trafficked women in Ghana. We find that experiencing sexual violence while being trafficked is associated with higher levels of both depression and posttraumatic stress years after the trafficking period ended. This indicates both the long-term effects of stress and the enduring nature of psychological distress among the women in this study. Our analytic account of how violent experiences while trafficked impact mental health over the period of reintegration contributes to the general literature on violence and mental health among women, as well as to literature on the health implications of human trafficking.

"I'm an adult now": Health risk behaviors and identifying as an adult.

Is identifying as an adult associated with lower rates of participation in risky behaviors? This study focuses on how identity affects health behaviors for young adults. We use an original sample of over 500 18- to 29-year-olds in the United States to explore how self-identification as an adult is associated with three clusters of health risk behaviors: substance use, risky sexual behavior, and risky driving behavior. Consistent with our predictions, we find that viewing oneself as an adult is associated with lower levels of participation in each of the health risk behavior outcomes.

A Review of Prevalence Estimation Methods for Human Trafficking Populations.

Human trafficking has long-lasting implications for the well-being of trafficked people, families, and affected communities. Prevention and intervention efforts, however, have been stymied by a lack of information on the scale and scope of the problem. Because trafficked people are mostly hidden from view, traditional methods of establishing prevalence can be prohibitively expensive in the recruitment, participation, and retention of survey participants. Also, trafficked people are not randomly distributed in the general population. Researchers have therefore begun to apply methods previously used in public health research and other fields on hard-to-reach populations to measure the prevalence of human trafficking. In this topical review, we examine how these prevalence methods used for hard-to-reach populations can be used to measure the prevalence of human trafficking. These methods include network-based approaches, such as respondent-driven sampling and the network scale-up method, and venue-based methods. Respondent-driven sampling is useful, for example, when little information about the trafficked population has been produced and when an adequate sampling frame does not exist. The network scale-up method is unique in that it does not target the hidden population directly. The implications of our work internationally include the need for documenting and validating the various prevalence estimation methods in the United States in a more robust way than was done in existing efforts. In providing this roadmap for estimating the prevalence of human trafficking, our overarching goal is to promote the equitable treatment and overall well-being of the socially disadvantaged populations who disproportionately experience human trafficking.

Violence predicts physical health consequences of human trafficking: Findings from a longitudinal study of labor trafficking in Ghana.

Research consistently finds high rates of both poor physical health and violent victimization among survivors of human trafficking. While this literature documents the immediate effects of human trafficking on health, no published literature has compared short- and longer-term physical health consequences of trafficking or examined the role of violence in shaping physical health outcomes across the period of reintegration. Here, we utilize longitudinal data to document the prevalence of various forms of violence experienced by women and girls trafficked for labor in Ghana, as well as examine the effects of violence on self-reported physical health conditions at two time points following exit from trafficking. Consistent with the stress process model, we find a higher prevalence of physical health complaints during the second wave of data collection, suggesting a delayed somatization effect. We also find that while psychological violence has a strong effect on the number of physical health complaints in the period immediately after exit from trafficking, sexual violence experienced while being trafficked is most predictive of physical health complaints later in the reintegration period. These findings have implications for understanding the role of violence, more generally, in shaping physical health. Our research also suggests the importance of monitoring the physical health of trafficking survivors beyond the immediate post-trafficking period and of providing on-going access to healthcare.

Sexual Revictimization: A Routine Activity Theory Explanation.

Research has shown that victims of sexual assault are at a significant risk of revictimization. We use routine activity theory to predict how sexual victimization in adolescence relates to depression, substance use, and ultimately revictimization as a young adult. We frame our research within routine activity theory and predict that sexual victimization increases substance use and depressive symptoms, both of which increase the likelihood of revictimization. We test the hypotheses with three waves of data from the Longitudinal Study of Violence Against Women. Using structural equation modeling, we examine the direct and indirect effects of previous sexual victimization, depressive symptoms, and substance use on the odds of victimization during the sophomore year of college. Results suggest that sexual victimization during the sophomore year of college is predicted directly by previous sexual victimization and also indirectly through depressive symptomology, though not substance use. Although understudied in the literature, depression is shown to mediate the relationship between victimization and revictimization, and this finding is consistent with routine activity theory, as well as the state dependence perspective on revictimization. Our findings suggest that depressive symptoms, a long acknowledged consequence of sexual victimization, should also be understood as a source of revictimization risk, indicating the importance of depression screening and intervention for decreasing sexual victimization.

Rape reporting: "Classic Rape" and the behavior of law.

Two theories of rape reporting, the Classic Rape perspective and Black's Theory of the Behavior of Law, are tested in this article. We offer the first comprehensive multivariate test of Classic Rape predictions among a nationally representative sample of victims, as well as the first test of Black's predictions for rape reporting. Through the construction of multinomial regression models, we are able to examine reporting patterns for both victims and third parties. Weapon use and physical injury consistently predicted reporting. The likelihood of victim reporting significantly increased when assaults occurred either in public or through a "home blitz," whereas place of assault did not affect the likelihood of third-party reporting. On the other hand, victim-offender relationship significantly affected the likelihood of third-party reporting but was not significant in the victim-reporting models. There were mixed findings regarding Black's stratification and morphology predictions, and we found no significant effects for culture, organization, or social control. Overall, these findings lend greater support to the Classic Rape perspective than to Black's model.

Communicating About Affirmative Consent: How the Threat of Punishment Affects Policy Support and Gender Stereotypes.

Colleges are increasingly adopting "affirmative consent" policies, which require students to obtain conscious and voluntary consent at each stage of sexual activity. Although this is an important step forward in violence prevention, very little is known about how best to present the policies to students. This is important, as research on sexual harassment policy training finds that training can reinforce traditional gender beliefs, which undermines policy goals. Building on this literature, we argue that affirmative consent policy trainings emphasizing punishment will increase support for affirmative consent but will reinforce traditional gender beliefs. We tested our predictions with an experiment in which we randomly assigned undergraduate participants to one of three conditions where they read an excerpt of (a) an affirmative consent policy that emphasized the threat of punishment, (b) an affirmative consent policy that emphasized a normative/moral message, or (c) an ergonomic workstation policy that served as our control condition. We found that punishment framing increased men's support for the policy, had no effect on their likelihood to comply, and increased their perception that "most people" hold men to be more powerful than women. For women, the punishment and normative framings increased support equally, but the normative framing actually decreased likelihood to comply. The policy conditions had no effect on women's gender beliefs. The results suggest that while an emphasis on punishment can help legitimate nonconsensual sex as a social problem, it will not necessarily increase college students' compliance with affirmative consent, and runs the risk of activating essentialist stereotypes about gender difference. As the issue of campus sexual assault becomes increasingly politicized and contested, our findings highlight the need for more research.

Rape reporting after reforms: have times really changed?

Using data from the National Violence Against Women Survey, the authors examine whether rapes committed after reforms were more likely to be reported to police than those committed before reforms. The authors also consider whether the gap between the reporting of simple versus aggravated rape has narrowed. They find that rapes committed after 1990 were more likely to be reported than rapes occurring before 1974. Aggravated rape continues to be more likely to be reported than simple rape, however, and this effect is stable over time. The authors conclude by discussing the implications of these findings for evaluating the success of rape reform statutes.

Avoiding rape: the effects of protective actions and situational factors on rape outcome.

While protective actions are consistently found to be important in rape avoidance, research is less clear on what forms of protective action are most effective. There is also little research on whether the effectiveness of particular protective actions varies depending upon the context of the assault. This study employs multivariate logistic regression to examine the situational effectiveness of physical, forceful verbal, and non-forceful verbal protective strategies using data from the National Crime Victimization Survey. It is predicted that failure to use physical and forceful verbal strategies will result in increased risk of rape as situational danger increases, while non-forceful verbal resistance will become less effective in more dangerous situations. Contrary to predictions, results indicate that the effectiveness of protective actions does not vary across most situations. Instead, among women who perform self-protective actions physical resistance is generally predictive of rape avoidance, forceful verbal resistance is ineffective, and non-forceful verbal resistance is predictive of rape completion.

The context of sexual violence: situational predictors of self-protective actions.

While considerable research has examined the relative effectiveness of different types of self-protective actions in rape avoidance, little research has considered how the situational context of the assault affects women's choice of self-protective strategy. Through an examination of data from the National Crime Victimization Survey, this article examines the extent to which situational factors are independently related to the use of physical resistance, verbal resistance, as well as to lack of resistance. The results of the multinominal logistic regression analysis indicate that those who used verbal self-protective action were more likely to have been attacked at night, threatened with a weapon, and to be assaulted by a prior or current romantic partner than were those who chose physical resistance. Those attacked by a current or former intimate were also more likely to employ no resistance than they were physical resistance. Victims facing a substance-using assailant, however, were more likely to enact physical self-protection than to employ no resistance.
