Sexual abuse history, alcohol intoxication, and women's sexual risk behavior

Causal Effects of Alcohol Consumption on Condom Negotiation Skills of Women with Varying Sexual Assault Histories

Sexual assault victimization experience and alcohol consumption are well-documented HIV risk factors for women who have sex with men (WSM). Nonetheless, behavioral mechanisms of the synergistic effects of these factors on women's increased HIV risk are not well delineated. This study is the first to examine the interactive effects of sexual assault history and acute intoxication on women's condom negotiation behavior during a face-to-face role-play with a male actor. Participants were female, single, social drinkers, ages 21 to 35, recruited from the community. Women were categorized as having experienced past sexual assault victimization or not based on their questionnaire responses, then were randomly assigned to consume either no alcohol or alcohol (0.08 target BAC) and engaged in a role-play with a male actor that included condom use negotiation. Participants' verbal, paraverbal, and nonverbal behavior was video recorded and coded by independent raters. As hypothesized, sexual assault history interacted with alcohol condition to significantly influence participants' assertive condom negotiation behavior. These results further our scientific understanding of how intoxication may exacerbate the relationship between sexual assault history and HIV risk, and can inform prevention programs tailored to the unique needs of WSM who have a history of sexual assault victimization and are social drinkers.

Alcohol, Sexual Arousal, and Partner Familiarity as Predictors of Condom Negotiation: An Experience Sampling Study

Numerous contextual factors contribute to risky sexual decision-making among men who have sex with men (MSM), with experimental laboratory-based studies suggesting that alcohol consumption, sexual arousal, and partner familiarity have the potential to impact condom negotiations during sexual encounters. The purpose of the current study was to extend this line of inquiry outside of the laboratory and into the everyday lives of MSM. We collected six weeks of daily data on alcohol consumption and sexual behaviors from 257 moderate- and heavy-drinking MSM to examine the within- and between-subjects effects of alcohol consumption, average daily sexual arousal, and partner familiarity on condom negotiation processes during sexual encounters. We hypothesized that alcohol consumption, higher levels of average daily sexual arousal, and greater partner familiarity would all contribute to a reduced likelihood of condom negotiation prior to sexual activity, and that they would also affect the difficulty of negotiations. Contrary to hypotheses, none of these three predictors had significant within-subjects effects on condom negotiation outcomes. However, partner familiarity and average daily sexual arousal did exert significant between-subjects effects on the incidence of negotiation and negotiation difficulty. These findings have important implications for risk-reduction strategies in this population. They also highlight the challenges of reconciling results from experimental laboratory research and experience sampling conducted outside of the laboratory on sexual risk behavior.

Relational and Trait Factors Mediate the Associations between Women's Intoxication-Related Unwanted Sexual Experiences, Pleasure, and Desire

Despite documented negative sexual health sequelae of unwanted sexual contact (USC), it is unclear why individuals who have experienced USC within the context of intoxication (intoxication-related USC) are at particular risk for poor sexual functioning. Intoxication-related USC may impact relational factors like relationship satisfaction, as trauma symptoms interfere with emotional closeness during sex. Additionally, although individual traits - such as sexual excitation and sensation seeking - affect the relationship between trauma and sexual functioning, it is unknown whether these factors differentially impact those who have experienced intoxication-related USC. Finally, because presence of a partner may evoke trauma-related symptoms during partnered (dyadic) sexual activity, mediators may differ across solitary versus dyadic sexual pleasure and desire. We tested relational and individual trait mediators of the association between intoxication-related USC and solitary and dyadic sexual pleasure and desire in a sample of heterosexual and sexual minority women. Trait factors consistently mediated the association between intoxication-related USC and both dyadic and solitary desire and pleasure, while relational factors such as emotional closeness were inconsistently related to sexual wellbeing. If replicated, these findings would suggest that trait factors may be useful targets for clinical sexual wellness interventions among sexuality-diverse women who have experienced intoxication-related USC.

How Alcohol Influences Mechanisms of Sexual Risk Behavior Change: Contributions of Alcohol Challenge Research to the Development of HIV Prevention Interventions

This paper examines the contributions of laboratory-based alcohol challenge research (ACR) to the development of HIV prevention interventions. Following a brief overview of HIV prevention interventions and related health behavior change models, we discuss how alcohol may influence mechanisms of behavior change. The paper highlights the value of ACR for: (1) elucidating mechanisms of action through which alcohol affects sexual risk behavior, (2) testing how alcohol may influence mechanisms thought to underlie HIV prevention interventions, (3) clarifying moderators of the causal influences of alcohol, (4) identifying novel intervention targets, and (5) developing strategies to reduce sexual risk among those who consume alcohol. We conclude with a discussion of the importance of using experimental research to identify mechanisms of behavior change that are specific to populations at high risk for HIV and outline some key implications for developing HIV prevention interventions that integrate the role of alcohol.

Childhood Sexual Abuse and Adult Sexual Risk Behavior: A Review and Critique

Childhood sexual abuse (CSA) is a global problem with serious repercussions for survivors in various domains of adult interpersonal functioning, including sexual risk behavior. This review aimed to summarize findings from the recent literature on the connections between CSA and later adult sexual risk behaviors (e.g., unprotected intercourse, sexually transmitted infection [STSI] diagnosis). The sexual risk behaviors consistently associated with CSA were having sex under the influence of alcohol/substances and reports of concurrent sexual partners/infidelity. Notably, studies investigating the links between CSA and history of STI diagnosis and CSA and reports of unprotected sex (with the exception of samples comprised men who have sex with men) produced inconsistent findings. The methodological limitations of existing studies are considered and suggestions for future research are offered.

Asian American Women's Victimization History and In-The-Moment Responses to Partner Violence

Between 20% and 50% of Asian American women report experiencing partner violence (PV). Furthermore, nearly half of PV victims experience their first assault between the age of 18 and 24 years, suggesting that Asian American college women may be particularly at risk of PV. Experiencing childhood abuse (CA) may impair women's capacity to perceive risk during a potential PV situation, increasing their risk for revictimization. The purpose of the current study was to examine differences among Asian American college women's (N = 324) in-the-moment behavioral intention, risk perception, and likelihood to stay in an abusive relationship during a progressively threatening PV scenario, based on victimization history and posttraumatic stress disorder (PTSD) symptoms. We tested three path models, each assessing the relations among CA, PV, PTSD, current and future risk perception, likelihood of staying in the relationship, and one of three behavioral intentions (soothe the perpetrator, escape, and escalation/resistance). As hypothesized, CA history positively predicted PV history and PTSD symptoms. Furthermore, CA and PV predicted more in-the-moment soothe behavioral intentions and fewer escape behavioral intentions which, in turn, predicted diminished current and future risk perception. CA and PV also predicted stronger escalation/resistance behavioral intentions, such that escalation/resistance intentions were associated with higher risk perception during a more violent part of the scenario but lower risk perception during a less violent part of the scenario. Finally, higher risk perception predicted lower likelihood of staying in the relationship. Findings indicate that victimization history is associated with increased risky behavioral intentions among Asian American college women and suggest that targeted interventions to improve assault-exposed Asian American women's awareness of risk cues may be warranted.

The Effects of Childhood Sexual Abuse: The Role of Anxiety and Alcohol Use among Haitian Women Living with HIV

Childhood abuse has been linked to problematic drinking in adulthood. It is also documented that people living with HIV have higher rates of alcohol use than the general population. In Haiti, a total of 25% of women living with HIV have experienced childhood sexual abuse (CSA), which puts them at an increased risk for alcohol abuse. CSA has also been associated with anxiety disorders in adulthood. Therefore, it is critical to understand the relationship between CSA, anxiety, and alcohol use among women living with HIV. A total of 244 women living with HIV participated in this study, with 35% reporting CSA. Alcohol abuse was measured with the AUDIT, anxiety with the State-Trait Anxiety Inventory test, and sexual abuse with the Childhood Trauma Questionnaire. Compared to participants who did not experience childhood sexual abuse, participants who experienced childhood sexual abuse reported greater levels of alcohol use [(17.0, SD = 9.1) (11.9, SD = 8.6) p =.001] and anxiety [(55.8, SD = 9.8) (48.9 SD = 8.3) p =.001] respectively. The indirect effect of anxiety on the association between CSA and alcohol use was significant [(ß =.19 p =.05) 95% bootstrap CI.019 -.13] Thus, women who reported being sexually abused as children reported anxiety, which in turn, was associated with an increased risk for alcohol abuse. Results demonstrate that alcohol may be used as a negative coping mechanism to alleviate anxiety symptoms triggered by CSA. These findings elucidate the need for further research examining the impact that sexual trauma has on mental health.

Alcohol and Sexual Health Behavior: "What We Know and How We Know It"

Alcohol, despite salutary associations with sexuality, has been implicated in sexual health problems. This review examines the relationship between alcohol and outcomes related to sexual health. Methodological considerations limiting causal assertions permissible with nonexperimental data are discussed, as are advantages of experimental methods. Findings from laboratory experiments are reviewed evaluating causal effects of acute alcohol intoxication on a variety of outcomes, including sexual arousal, sexual desire, orgasm, and sexual risk behaviors related to sexually transmitted infections (STIs) and human immunodeficiency virus (HIV). Several variables exerting mediating and moderating influences are identified. It is concluded that acute alcohol intoxication is capable of exerting a causal impact on multiple constituent components of sexual responding related to sexual health. Both alcohol expectancy and alcohol myopia theories have been supported as explanations for these causal effects. Furthermore, for sexual risk behavior, noteworthy recent developments include research highlighting the importance of women's sexual victimization history and men's condom use resistance. Limitations and implications associated with this body of research are also discussed.

Sexual Arousal and Implicit and Explicit Determinants of Condom Use Intentions

Being sexually aroused may be an important risk factor contributing to sexual decision making. Dual-process cognitive models, such as the reflective-impulsive model of Strack and Deutsch (2004), could be used to explain the effect of sexual arousal on intentions to use a condom. In this study, we investigated whether explicit and implicit attitudes toward condom use can predict intentions to use a condom when participants are sexually aroused and not aroused. In a within-subjects experimental design, male participants (N = 27) watched both a neutral and an erotic movie clip in counterbalanced order. After each clip, participants completed a questionnaire assessing their intentions to use a condom and explicit condom attitudes, followed by a wanting Implicit Association Test (IAT; Greenwald et al., 2003) and a liking IAT to assess their implicit attitudes to unsafe sex. In concordance with the reflective-impulsive model, we found that when participants were not sexually aroused, their intentions to use a condom were solely predicted by their explicit attitudes. However, when they were sexually aroused, intentions to use a condom were predicted by both explicit and implicit attitudes toward condom use.

History of child sexual abuse among women consuming illicit substances in Mexico City

INTRODUCTION

Child sexual abuse (CSA) is a pervasive problem that has been linked to numerous developmental, social, health, and substance use consequences. Nevertheless, the relationship between CSA and the consumption of psychoactive substances has not been adequately studied in Mexico. The present study aims to examine this association between history of CSA and illicit substance use and associated risk behaviors in a sample of young adult women in Mexico City.

DESIGN AND METHODS

The present study uses a cross-sectional design to examine sexual abuse history among women who use illicit substances. Data collection consisted of a questionnaire administered through face-to-face interviews with 101 women who sought treatment for substance use in Mexico City. A bivariate analysis was used to examine women who experienced sexual abuse and those who did not. Odds ratio and relative risk were estimated.

RESULTS

A total of 101 women were interviewed with an average age of 19.2 years. The average age of onset of drug use was 15.4 years. Among participants, 68% reported having been victims of sexual abuse and rape. The average age of reported sexual abuse was 12.2 years. Participants reported a high rate of polydrug use (32.7%), consuming more than two drugs. Sexual abuse was associated with detention by police for drugs, forced prostitution, and consumption of substances during pregnancy.

DISCUSSION AND CONCLUSIONS

This study found that sexual abuse and rape were highly associated with substance abuse outcomes and associated risk behaviors.

Does being drunk or high cause HIV sexual risk behavior? A systematic review of drug administration studies

HIV sexual risk behavior is broadly associated with substance use. Yet critical questions remain regarding the potential causal link between substance use (e.g., intoxication) and HIV sexual risk behavior. The present systematic review was designed to examine and synthesize the existing literature regarding the effects of substance administration on HIV sexual risk behavior. Randomized controlled experiments investigating substance administration and HIV sexual risk behavior (e.g., likelihood of condom use in a casual sex scenario) were included. Across five databases, 2750 titles/abstracts were examined and forty-three total peer reviewed published manuscripts qualified (few were multi-study manuscripts, and those details are outlined in the text). The majority of articles investigated the causal role of acute alcohol administration on HIV sexual risk behavior, although one article investigated the effects of acute THC administration, one the effects of acute cocaine administration, and two the effects of buspirone. The results of this review suggest a causal role in acute alcohol intoxication increasing HIV sexual risk decision-making. Although evidence is limited with other substances, cocaine administration also appears to increase sexual risk, while acute cannabis and buspirone maintenance may decrease sexual risk. In the case of alcohol intoxication, the pharmacological effects independently contribute to HIV sexual risk decision-making, and these effects are exacerbated by alcohol expectancies, increased arousal, and delay to condom availability. Comparisons across studies showed that cocaine led to greater self-reported sexual arousal than alcohol, potentially suggesting a different risk profile. HIV prevention measures should take these substance administration effects into account. Increasing the amount of freely and easily accessible condoms to the public may attenuate the influence of acute intoxication on HIV sexual risk decision-making.

Attentional Bias for Sexual Threat Among Sexual Victimization Survivors: A Meta-Analytic Review

The current meta-analysis examined the effects of sexual victimization (SV) on attentional bias for sexual threat. This relationship was also examined among victims of SV with and without a current diagnosis of post-traumatic stress disorder (PTSD). The broader aim was to elucidate potential mechanisms operating between SV and negative health outcomes. As hypothesized, the findings supported a positive relationship between SV and attentional bias toward sexual threat stimuli, and subanalyses indicated that PTSD symptomatology significantly contributed to this association.

Women's Sex-Related Dissociation: The Effects of Alcohol Intoxication, Attentional Control Instructions, and History of Childhood Sexual Abuse

This study examined influences of alcohol intoxication, attentional control, and childhood sexual abuse (CSA) severity on sex-related dissociation. Sex-related dissociation is defined here as dissociation (e.g., feeling as if the world is unreal and feeling disconnected from one's body) during sexual activity or in the presence of sexual stimuli. Women (N = 70) were randomized to a 2 (alcohol condition: none,.10% peak breath alcohol concentration) X 2 (attentional control instructions: none, "relax and maximize" sexual arousal) experiment and exposed to sexual stimuli. Alcohol intoxication was positively associated with sex-related dissociation. CSA severity and sex-related dissociation were positively associated in the no-instruction condition but not in the "relax and maximize" condition. For some women, efforts to relax and maximize sexual arousal may buffer the association between CSA and sex-related dissociation.

Reducing sexual risk behaviors: secondary analyses from a randomized controlled trial of a brief web-based alcohol intervention for underage, heavy episodic drinking college women

BACKGROUND

Alcohol use and sexual risk behaviors (SRBs) are significant problems on college campuses. College women are at particularly high risk for negative consequences associated with sexually transmitted infections (STIs) and unwanted pregnancy.

METHODS

The current study (n = 160) examined the effect of a brief, web-based alcohol intervention (n = 53) for college women on reducing SRBs compared to an assessment only control (n = 107) with a randomized controlled trial. Outcome measures included condom use assertiveness and number of vaginal sex partners and data were collected at baseline and three-month follow-up.

RESULTS

Regression analyses revealed that the alcohol intervention was associated with higher levels of condom use assertiveness at a three-month follow-up. Additionally, more alcohol use was associated with less condom use assertiveness for those with more significant sexual assault histories.

CONCLUSIONS

These findings suggest that alcohol interventions may impact college women's beliefs but not behavior, and future interventions should more explicitly target both alcohol and sexual risk to decrease risky behaviors.

From Sexual Assault to Sexual Risk: A Relational Pathway?

Among women and gay and bisexual men, sexual assault is associated with increased rates of sexual risk behavior and negative sexual health outcomes. Although the mechanisms of these effects are potentially myriad, the current analyses examine the role of perceived partner pressure for condomless sex in mediating the association between adult sexual assault (ASA) and recent anal or vaginal sex without a condom. In a sample of 205 young adult women and gay and bisexual men, ASA was indirectly associated with condomless anal and/or vaginal sex via perceptions of partner pressure for condomless sex, χ²(1) = 5.66, p = .02, after controlling for race, age, gender and sexual identity, and relationship status. The elucidation of this relational mechanism points to several potential intervention and prevention strategies that may reduce actual and perceived pressure for sex without a condom, including strategies designed to facilitate the prioritization of health and safety over relational goals and the improvement of partner selection and perceptions of partner pressure.

Toward Development of Enhanced Preventive Interventions for HIV Sexual Risk among Alcohol-Using Populations: Confronting the 'Mere Pause from Thinking'

The papers in this issue detail state-of-the science knowledge regarding the role of alcohol use in HIV/AIDS risk, as well as offer suggestions for ways forward for behavioral HIV prevention for at-risk alcohol-using populations. In light of recent evidence suggesting that the anticipated uptake of the newer biomedical HIV prevention approaches, prominently including pre-exposure prophylaxis, has been stalled owing to a host of barriers, it has become ever more clear that behavioral prevention avenues must continue to receive due consideration as a viable HIV/AIDS prevention approach. The papers collected here make a valuable contribution to "combination prevention" efforts to curb HIV spread.

Alcohol Use Predicts Sexual Decision-Making: A Systematic Review and Meta-Analysis of the Experimental Literature

Alcohol is associated with HIV and other sexually transmitted infections through increased sexual risk-taking behavior. Establishing a causal link between alcohol and sexual behavior has been challenging due to methodological limitations (e.g., reliance on cross-sectional designs). Experimental methods can be used to establish causality. The purpose of this meta-analysis was to evaluate the effects of alcohol consumption on unprotected sex intentions. We searched electronic bibliographic databases for records with relevant keywords; 26 manuscripts (k = 30 studies) met inclusion criteria. Results indicate that alcohol consumption is associated with greater intentions to engage in unprotected sex (d +s = 0.24, 0.35). The effect of alcohol on unprotected sex intentions was greater when sexual arousal was heightened. Alcohol consumption is causally linked to theoretical antecedents of sexual risk behavior, consistent with the alcohol myopia model. Addressing alcohol consumption as a determinant of unprotected sex intentions may lead to more effective HIV interventions.

Men's Intentions to Have Sex With a New Partner: Sexual and Emotional Responding, Alcohol, and Condoms

Findings regarding the relation between alcohol and intentions to have sex have been mixed, and little research has examined the role of condom availability on intentions to have sex. Sexual and emotional responding may influence subsequent sexual decisions. Thus, a better understanding of sexual and emotional responding combined with situational factors such as condom presence could help explain the discrepancies in findings regarding alcohol's effect on intentions to have sex. The effects of alcohol and condom presence on men's intentions to have sex were examined using an experimental paradigm involving an alcohol administration study and a second-person eroticized scenario. The effects of sexual and emotional responding were also examined in relation to intentions to have sex. It was found that alcohol increased positive mood, which was associated with higher intentions to have sex. In addition, condom presence was directly associated with higher intentions to have sex. More sexual desire was related to increased likelihood of sexual intentions. These findings increase understanding of mechanisms underlying the relation between alcohol and intentions to have sex.

How to Score the Sexual Experiences Survey? A Comparison of Nine Methods

OBJECTIVE

Although assessments of sexual assault victimization and perpetration have greatly improved, current scoring methods do not fully utilize the wealth of information they provide. The present studies assessed new methods for scoring sexual assault severity using the Sexual Experiences Survey (SES; Koss et al., 2007).

METHOD

In two studies of female (n = 436) and male (n = 313) non-problem drinkers who had engaged in unprotected sex within the past year, we compared three severity ranking schemes as well as three scoring methods per severity scheme for a total of nine scoring methods. New severity ranking schemes considered tactic types separately, varied combinations of assault outcomes, and accounted for multiple types and frequencies of assaults. Measures assessing convergent validity were also administered.

RESULTS

Seventy-eight percent (n = 340) of the women reported victimization, and 58% (n = 180) of the men reported perpetration. All severity scoring methods were strongly associated with convergent measures.

CONCLUSIONS

Each scoring method is viable; however especially among samples with greater victimization/perpetration rates, there can be advantages to incorporating multiple types and frequencies of assault experiences into SES scores. Recent refinements of the SES necessitate commensurate improvements in its scoring methods in order to significantly advance the field of sexual assault assessment.

Sexual victimization, alcohol intoxication, sexual-emotional responding, and sexual risk in heavy episodic drinking women

This study used an experimental paradigm to investigate the roles of sexual victimization history and alcohol intoxication in young women's sexual-emotional responding and sexual risk taking. A nonclinical community sample of 436 young women, with both an instance of heavy episodic drinking and some HIV/STI risk exposure in the past year, completed childhood sexual abuse (CSA) and adolescent/adult sexual assault (ASA) measures. A majority of them reported CSA and/or ASA, including rape and attempted rape. After random assignment to a high alcohol dose (.10 %) or control condition, participants read and projected themselves into an eroticized scenario of a sexual encounter involving a new partner. As the story protagonist, each participant rated her positive mood and her sexual arousal, sensation, and desire, and then indicated her likelihood of engaging in unprotected sex. Structural equation modeling analyses revealed that ASA and alcohol were directly associated with heightened risk taking, and alcohol's effects were partially mediated by positive mood and sexual desire. ASA was associated with attenuated sexual-emotional responding and resulted in diminished risk taking via this suppression. These are the first findings indicating that, compared to non-victimized counterparts, sexually victimized women respond differently in alcohol-involved sexual encounters in terms of sexual-emotional responding and risk-taking intentions. Implications include assessing victimization history and drinking among women seeking treatment for either concern, particularly women at risk for HIV, and alerting them to ways their histories and behavior may combine to exacerbate their sexual risks.

Using vignettes in qualitative research to explore barriers and facilitating factors to the uptake of prevention of mother-to-child transmission services in rural Tanzania: a critical analysis

Background

Vignettes are short stories about a hypothetical person, traditionally used within research (quantitative or qualitative) on sensitive topics in the developed world. Studies using vignettes in the developing world are emerging, but with no critical examination of their usefulness in such settings. We describe the development and application of vignettes to a qualitative investigation of barriers to uptake of prevention of mother-to-child transmission (PMTCT) HIV services in rural Tanzania in 2012, and critique the successes and challenges of using the technique in this setting.

Methods

Participatory Learning and Action (PLA) group activities (3 male; 3 female groups from Kisesa, north-west Tanzania) were used to develop a vignette representing realistic experiences of an HIV-infected pregnant woman in the community. The vignette was discussed during in-depth interviews with 16 HIV-positive women, 3 partners/relatives, and 5 HIV-negative women who had given birth recently. A critical analysis was applied to assess the development, implementation and usefulness of the vignette.

Results

The majority of in-depth interviewees understood the concept of the vignette and felt the story was realistic, although the story or questions needed repeating in some cases. In-depth interviewers generally applied the vignette as intended, though occasionally were unsure whether to steer the conversation back to the vignette character when participants segued into personal experiences. Interviewees were occasionally confused by questions and responded with what the character should do rather than would do; also confusing fieldworkers and presenting difficulties for researchers in interpretation. Use of the vignette achieved the main objectives, putting most participants at ease and generating data on barriers to PMTCT service uptake. Participants’ responses to the vignette often reflected their own experience (revealed later in the interviews).

Conclusions

Participatory group research is an effective method for developing vignettes. A vignette was incorporated into qualitative interview discussion guides and used successfully in rural Africa to draw out barriers to PMTCT service use; vignettes may also be valuable in HIV, health service use and drug adherence research in this setting. Application of this technique can prove challenging for fieldworkers, so thorough training should be provided prior to its use.

The role of alcohol use during sexual situations in the relationship between sexual revictimization and women's intentions to engage in unprotected sex

Research has demonstrated relationships among childhood sexual abuse, adult sexual assault, and sexual risk taking. This study proposes that one mechanism through which the victimization-sexual risk-taking relationship works is through an increased likelihood of drinking during sexual situations. Using path analysis, this study explores this hypothesis in a sample of 230 women. The model illustrates that women with a history of child and adult sexual victimization reported greater intentions to engage in unprotected sex and that this relationship is in part accounted for by an increased likelihood of drinking in sexual situations. The results suggest that sexual risk reduction programs and sexual assault treatment programs should educate women about the alcohol-involved sexual risk taking that often follows sexual assault victimization.

Verbal Sexual Coercion Experiences, Sexual Risk, and Substance Use in Women

Research has linked sexual assault, substance use, and sexually transmitted infection (STI) risk in women. Sexual assault by means of verbal sexual coercion (VSC) is more common than sexual assault by means of physical tactics, but VSC is rarely assessed independently. In addition, past work has established global connections among substance use, sexual assault history, and STI risk; however, assessing substance use during sexual behavior is less common. This study examined the relations among VSC, STI risk behavior, and substance use and attitudes. We hypothesized that women with larger numbers of VSC experiences would report more frequent sexual risk behaviors and substance use and attitudes. Participants with larger numbers of VSC experiences reported larger numbers of anal sex partners, more frequent penile-vaginal sex and sexual activity after substance use, and stronger sex-related alcohol expectancies. These findings suggest that VSC is associated with higher levels of STI risk in women.

Women's unprotected sex intentions: roles of sexual victimization, intoxication, and partner perception

Sexually victimized women may make sexual decisions differently than nonvictimized women. This study used an eroticized scenario and laboratory alcohol administration to investigate the roles of victimization history, intoxication, and relationship context in women's perceptions of a male partner and their subsequent intentions for unprotected sex. A community sample of 436 women completed childhood sexual abuse (CSA) and adolescent/adult sexual assault (ASA) measures. After random assignment to an alcohol or control condition, participants read and projected themselves into a sexual scenario that depicted the male partner as having high or low potential for a lasting relationship. Participants rated their perceptions of his intoxication, sexually transmitted infection (STI) risk level, and anticipated reactions to insistence on condom use. They then indicated their likelihood of allowing the partner to decide how far to go sexually (abdication) and of engaging in unprotected sex. Structural equation modeling (SEM) analyses revealed that intoxication predicted greater unprotected sex likelihood indirectly via abdication. CSA and ASA predicted partner perceptions, which in turn predicted unprotected sex likelihood. These findings indicate that, compared to their nonvictimized counterparts, sexually victimized women may respond differently in sexual encounters partly as a function of their perceptions of partners' STI risk and anticipated reactions to condom insistence.

Sexual sensation seeking, co-occurring sex and alcohol use, and sexual risk behavior among adolescents in treatment for substance use problems

OBJECTIVE

This study evaluated relations between sexual sensation seeking, co-occurring sex and alcohol use, and sexual risk behaviors (eg, unprotected intercourse and multiple sex partners) among adolescents receiving treatment for substance abuse problems.

METHOD

The ethnically diverse sample included 394 adolescents recruited from outpatient treatment (280 males; Mage  = 16.33 years, SDage  = 1.15). Structural equation modeling (SEM) was used to test direct and indirect paths between sexual sensation seeking and sexual risk behaviors via the frequency of co-occurring sex and alcohol use. Conditional indirect effects by gender were also tested.

RESULTS

Analyses identified significant effects of sexual sensation seeking on co-occurring sex and alcohol use and sexual risk behaviors. The path from co-occurring sex and alcohol use to unprotected intercourse was significantly stronger among adolescent girls, suggesting a mediation effect moderated by gender. No gender difference was found for the indirect path from sexual sensation seeking and number of past year sexual partners via co-occurring sex and alcohol use.

CONCLUSIONS

Selected prevention efforts are needed to promote HIV risk reduction among adolescents in substance abuse treatment. The documented conditional indirect effect for unprotected intercourse suggests that HIV prevention programs should pay special attention to gender-specific patterns of alcohol use and sexual risk behavior when tailoring program content. (Am J Addict 2013; 22:197-205).

Influences of situational factors and alcohol expectancies on sexual desire and arousal among heavy-episodic drinking women: acute alcohol intoxication and condom availability

Although studies suggest that alcohol increases women's sexual desire, no studies to our knowledge have examined the effects of acute alcohol intoxication on women's sexual desire. The majority of research examining alcohol's effects on sexual arousal in women suggests that alcohol increases self-reported arousal. In an alcohol administration study in which women projected themselves into an eroticized scenario depicting a consensual sexual encounter with a new male partner, we examined the effects of alcohol and condom condition on women's sexual desire and arousal. The moderating effects of sex-related alcohol expectancies were also examined. Results revealed that alcohol intoxication was related to less desire to engage in sex with a new partner and condom presence was related to more desire. Alcohol interacted with sexual disinhibition alcohol expectancies, indicating that more expectancy endorsement was associated with greater sexual desire and self-reported arousal in the alcohol condition, but not the control condition. Condom condition had no effect on self-reported sexual arousal. The present research suggests that sexual desire merits research attention in non-clinical samples, and experimental methodology can provide valuable information about alcohol's influence on women's sexual desire, thus advancing our understanding of this relationship beyond cross-sectional correlations. The current findings also provide evidence that sex-related alcohol expectancies may play an important role in alcohol-involved sexual experiences including desire and arousal.

Sexual harassment among young tourists visiting Mediterranean resorts

Despite the known increase in substance use and risky sexual behaviors among young people during holiday periods, issues of sexual harassment (SH) and having sex against one's will (SAW) have not received adequate attention. We implemented a cross-sectional airport-based study to identify experience of SH and SAW in 6,502 British and German holidaymakers aged 16-35 years visiting tourist resorts in Southern Europe (Crete, Cyprus, Italy, Portugal, and Spain) in summer 2009. Across all participants, 8.6 % reported SH during their holiday and 1.5 % reported SAW. Women reported higher levels of SH than heterosexual males. However, gay and bisexual males reported SH levels similar to females and the highest levels of SAW. Of 19 predictor variables tested, ten were independently associated with SH. SH was increased in those who were visitors to Mallorca or Crete, British, younger, female, gay or bisexual, frequently drunk on holiday, cocaine users, and attracted to bars where people get drunk, or where there are opportunities for sex. Among 13 predictor variables tested for SAW, four were significant. SAW reduced in those visiting Cyprus, and was strongly associated with being a gay or bisexual male, using cannabis on holiday and being attracted to bars where there were opportunities for sex. Holiday resorts represent a key location for SH and SAW, especially for holidaymakers who get drunk and use drugs. Preventive programs can raise awareness of the risks of unwanted sexual encounters on holiday and work with the tourist industry and tourist authorities to develop environments where sexual aggression is not tolerated.

Violence as a barrier for HIV prevention among female sex workers in Argentina

BACKGROUND

Violence against female sex workers (FSWs) has been increasingly reported as an important determinant of HIV infection risk. This study explores the frequency of different violent experiences (sexual abuse, rejection, beating and imprisonment) among FSWs in Argentina and its association with condom use and HIV and T. pallidum prevalence.

METHODS

A convenience sample of 1255 FSWs was included in a cross-sectional study conducted between October 2006 and November 2009.

RESULTS

Sexual abuse was reported by 24.1% (219/907) of women. A total of 34.7% (42/1234) reported rejection experiences, 21.9% (267/1215) reported having been beaten and 45.4% (561/1236) stated having been arrested because of their sex work activity. There was a higher frequency of inconsistent condom use with clients among FSWs who had experienced sexual abuse, rejection, and police detention. A higher frequency of HIV and T. pallidum infection was detected among FSWs who reported having been arrested by the police.

CONCLUSION

The study shows for the first time the frequency of different violent situations among FSWs in Argentina. The association between violence against sex workers, condom use and STI prevalence demonstrated here calls for measures to reduce stigma and violence against FSWs. Such violent experiences may increase vulnerability to STI through coerced unprotected sex.

Methamphetamine use is associated with childhood sexual abuse and HIV sexual risk behaviors among patrons of alcohol-serving venues in Cape Town, South Africa

BACKGROUND

South Africa's Western Cape has experienced a dramatic increase in methamphetamine ("meth") use over the past decade. There is concern that meth may further fuel the HIV epidemic in this country because of its association with risky sexual behaviors. This study describes the prevalence of meth use and its relation to HIV sexual risk behaviors among patrons of alcohol-serving venues.

METHODS

Participants (N=3328) were surveyed in 12 venues in a mixed race township. Logistic regression models were used to examine the relations between meth use and sexual risk behaviors, and structural equation models were used to test whether meth use mediates the relationship between childhood sexual abuse and current sexual risk.

RESULTS

Meth use in the past 4 months was more common among Coloured than Black persons (10.5% vs. 3.5%). Meth users were more likely than non users to use marijuana, inhalants, and injection drugs, have a history of childhood sexual and/or physical abuse, and experience and/or perpetrate intimate partner violence. Among both men and women, meth use was associated with greater odds of engaging in sexual risk behaviors, and meth use partially mediated the relationships between childhood sexual abuse and all sexual risk behaviors.

CONCLUSIONS

Meth users in this setting are at increased risk for HIV due to their greater likelihood of engaging in sexual risk behaviors and being in violent relationships. There is an urgent need to provide targeted HIV prevention and substance abuse treatment to meth users living in townships in Cape Town.

Mechanisms Underlying Sexual Violence Exposure and Psychosocial Sequelae: A Theoretical and Empirical Review

Sexual violence is associated with a range of negative mental health and behavioral sequelae, including posttraumatic stress disorder (PTSD), depression, substance abuse/dependence, risky sexual behavior, and interpersonal relationship problems. However, mechanisms underlying these associations are not well understood. Identifying mechanisms that explain linkages between sexual violence and poor outcomes is of paramount importance in determining when and how to intervene to prevent or reduce the magnitude of these outcomes. This review focuses on theories that have been proposed to explain risk of negative outcomes among sexual violence victims, including the development of traumagenic dynamics and emotion dysregulation. We also review promising biological mechanisms that may explain the risk of negative outcomes among sexual violence victims, including studies concerned with epigenetic and neurobiological mechanisms.

Alcohol consumption and the intention to engage in unprotected sex: systematic review and meta-analysis of experimental studies

AIMS

To review and analyse in experimentally controlled studies the impact of alcohol consumption on intentions to engage in unprotected sex. To draw conclusions with respect to the question of whether alcohol has an independent effect on the incidence of human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs).

METHODS

A systematic review and meta-analysis of randomized controlled studies examined the association between blood alcohol content (BAC) and self-perceived likelihood of using a condom during intercourse. The systematic review and meta-analysis were conducted according to internationally standardized protocols (Preferred Reporting Items for Systematic Reviews and Meta-Analyses: PRISMA). The meta-analysis included an estimate of the dose-response effect, tests for publication bias and sensitivity analyses.

RESULTS

Of the 12 studies included in the quantitative synthesis, our pooled analysis indicated that an increase in BAC of 0.1 mg/ml resulted in an increase of 5.0% (95% CI: 2.8-7.1%) in the indicated likelihood (indicated by a Likert scale) of engaging in unprotected sex. After adjusting for potential publication bias, this estimate dropped to 2.9% (95% CI: 2.0-3.9%). Thus, the larger the alcohol intake and the subsequent level of BAC, the higher the intentions to engage in unsafe sex. The main results were homogeneous, persisted in sensitivity analyses and after correction for publication bias.

CONCLUSIONS

Alcohol use is an independent risk factor for intentions to engage in unprotected sex, and as risky sex intentions have been shown to be linked to actual risk behavior, the role of alcohol consumption in the transmission of HIV and other STIs may be of public health importance.

Women's sexual arousal: effects of high alcohol dosages and self-control instructions

The basic relationship between alcohol and women's sexual arousal - especially genital arousal - received little research attention for nearly 30 years (e.g. Wilson and Lawson, 1978) until very recently (e.g. George et al., 2009). To investigate hypotheses based on earlier findings and Alcohol Myopia Theory (AMT), two experiments evaluated the effects of high blood alcohol concentrations (BACs) and arousal instructional demands on indices of vaginal responding and self-reported sexual arousal. In Experiment 1, self-control instructions to maximize (versus suppress) arousal increased peak and average Vaginal Pulse Amplitude (VPA) change. Self-control also interacted with a target BAC of .08% (versus .00%) to influence latency to peak arousal onset: Intoxicated women instructed to maximize showed a shorter latency to peak arousal than did intoxicated women instructed to suppress; however, sober women showed an undifferentiated pattern. Also, in Experiment 1, the target BAC of .08% had no effect on VPA or subjective arousal measures. In Experiment 2, a target BAC of .10% (versus .00%) attenuated peak change and average change in VPA, but this dosage had no effects on latency to peak achieved arousal, or on subjective arousal. Instructions to maximize arousal (versus no instruction) had no effect on any arousal measures. Overall, among young moderate drinking women, alcohol had attenuating effects but only at the higher dosage. Maximize versus suppress instructions about arousal had predicted effects on arousal and interactive effects on latency, but only at the lower dosage. The findings highlight the importance of dosage and contextual factors in alcohol's impact on the variability of women's sexual responding.
