Gender Roles,Power Strategies,and Precautionary Sexual Self-Efficacy: Implications for Black and Latina Women's HIV/AIDS Protective Behaviors

This cross-sectional study tested a conceptual model of women's HIV/AIDS protective behaviors using gender roles, relationship power strategies, and precautionary sexual self-efficacy as predictors in a predominantly Black and Latina community sample of heterosexual women (N = 125). Results revealed no support for the full model, but partial confirmation for several components of the model. Education significantly predicted gender roles, and gender roles and use of direct power strategies were significant predictors of sexual self-efficacy. Most of the participants were married or partnered and were unconcerned about contracting HIV, suggesting that if women perceive that they are at low or no risk, their gender roles, power strategies, and precautionary sexual self-efficacy will be inconsequential to their HIV/AIDS risk reduction practices.     

Risk Reduction Therapy for Adolescents: Targeting Substance Use and HIV/STI-Risk Behaviors

This paper describes a family-based intervention for addressing both substance use and unprotected sexual behavior in adolescents presenting for outpatient substance use treatment. The intervention combines contingency management (CM) for adolescent substance use, which is a behavioral intervention modeled on the Community Reinforcement Approach, with a sexual risk reduction protocol that mirrors aspects of the CM model. As a family-based intervention, caregivers attend every session and actively collaborate with the therapist to address their youth’s behavior problems. The treatment is criterion-based with treatment duration determined by the youth’s achievement of reduced substance use and unprotected sexual behavior goals. A case study describes the implementation of this treatment with an adolescent presenting a history of polysubstance use and unprotected sexual intercourse. Following the adolescent and caregiver’s participation in weekly sessions, the adolescent demonstrated improvements in substance use, unprotected sexual behavior, and other behavior problems. Clinical summary data from two outpatient clinics reveal similar positive outcomes for youth receiving the intervention. This paper illustrates the potential utility of an integrated treatment approach targeting substance use and unprotected sexual behavior in an adolescent population.     

The Close Relationship Context and HIV/AIDS Risk Reduction Among Mexican Americans

The purpose of this study was to determine, within a community sample of 115 Mexican Americans, the association of relationship variables to participants' HIV risk perception, use of condoms, and HIV-related communication with a relationship partner. Hierarchical multiple regression analyses with the total sample and within each gender separately revealed that intimacy and commitment were related to HIV risk perception, condom use, and HIV-related communication even after effects of age, gender, acculturation, marital status, and length of relationship were controlled. The pattern of significant correlates differs, however, in the total, women-only, and men-only samples. Results suggest that intimacy and commitment are important elements of the close relationship context that should be considered in HIV risk reduction efforts among Mexican Americans.     

Impact of Abuse History on Adolescent African American Women's Current HIV/STD-Associated Behaviors and Psychosocial Mediators of HIV/STD Risk

This study examined if relationship power, sex refusal self-efficacy, or fear of condom negotiation mediated the relationship between abuse history and consistent condom use (CCU) among African American female adolescents (N?=?593). Participants with an abuse history (58%) were less likely to report CCU. Women with an abuse history reported less relationship power and self-efficacy for refusing sex and more fear of condom negotiation, none of which independently or jointly mediated the association between abuse and CCU. Notably, history of abuse was associated with CCU across mediator models despite inclusion of psychosocial mediators. This study demonstrates the importance of understanding adolescents' condom use behaviors within the context of their life experiences, especially past abuse history.

Power,Conflict, and Community: How Gendered Views of Political Power Influence Women's Political Ambition

We provide a novel approach to understanding the political ambition gap between men and women by examining perceptions of the role of politician. Across three studies, we find that political careers are viewed as fulfilling power‐related goals, such as self‐promotion and competition. We connect these goals to a tolerance for interpersonal conflict and both of these factors to political ambition. Women's lack of interest in conflict and power‐related activities mediates the relationship between gender and political ambition. In an experiment, we show that framing a political career as fulfilling communal goals—and not power‐related goals—reduces the ambition gap.     

Power Politics and the Balance of Risk: Hypotheses on Great Power Intervention in the Periphery

Great powers frequently initiate risky diplomatic and military interventions in the periphery—regions that do not directly threaten the security of a great power's homeland. Such risky interventions are driven by leaders' aversion to losses in their state's relative power, international status, or prestige. These leaders often persist in such courses of action even when they incur mounting political, economic, and military costs. More surprisingly, they undertake risky strategies toward other great powers in an effort to continue these failing interventions. Hypotheses concerning such interventions are derived from the prospect theory and defensive realist literatures.     

Negotiating Femininity: Power and Strategies of Mexican American Girls

Popular views that female development entails a loss of voice and power in relationships have not been explored with Latina girls. In this study, data were collected from eight low-income Mexican American girls in middle and high school using surveys and open-ended interview questions. The findings show they view others as holding traditional expectations about how girls should behave, whereas they themselves engage in a more complex critique and performance of femininities in relationships with their family, peers, and teachers. The findings challenge assumptions that girls experience a linear loss of voice during adolescence, and suggest a distinction between personal power and power to help others. Finally, they show the importance of culture in understanding how girls negotiate gender roles.     

Comparison of Marine and College Women's HIV/AIDS-Relevant Sexual Behaviors1

This study compares the heterosexual risk behaviors, perceptions of vulnerability to HIV/AIDS, and predictors of condom use of two groups of women with very different sexual and contraceptive histories and habits–college women and women in Marine Corps recruit training. The Marines' s]exual behaviors put them at greater risk of contracting HIV than the college students; that is, Marines reported more frequent intercourse with more partners, used condoms less frequently, and had less knowledge about HIV/AIDS transmission. Consistent with these differences, college students displayed a larger illusion of unique invulnerability than did the Marines. In general, the women who had more sexual partners and more frequent sexual intercourse were less likely to report regularly using condoms. In addition, the data provide support for Weinstein and Nicholich's (1993) recent suggestion that the relation between risk perception and risk behavior is different for different groups of people.     

Coping with Intimate Partner Violence: Battered Women's Use and Perceived Helpfulness of Emotion-Focused Coping Strategies

This study investigated intimate partner violence (IPV) victims' emotion-focused coping efforts, as well as their retrospective ratings of the perceived helpfulness of these efforts, in the context of a longitudinal study of battered women's experiences over time. Four hundred and six primarily African American, low-income battered women who had experienced IPV within the previous 12 months were interviewed. Patterns of coping use and perceived helpfulness were explored. The correlation between prevalence of use of emotion-focused coping strategies and perceived helpfulness of these strategies was examined, and results showed that the strategies used by more battered women were less helpful in dealing with feelings about abuse. Implications for clinical interventions with battered women are discussed.     

Women's Agency in a Context of Oppression: Assessing Strategies for Personal Action and Public Policy

Popular debates about “victim feminism” have receded but underlying concerns about the extent of gender inequality and usefulness of strategies highlighting difference are still relevant. This paper applies Susan Wendell's framework—relating to women's agency under conditions of oppression—to the experience of women firefighters. The framework fits well, but one case reveals the need to modify it by attending to community. An elaboration of the framework is then used to examine four policy issues.     

Toward Theory Development and Measure Evolution for Studying Women's Relationships and HIV Infection

This commentary reviews and integrates selected empirical findings from this special issue of Sex Roles on Gender, Power, and Women's Relationships: Implications for HIV. Then the effects of current definitions of certain social science practices on theory development in these areas are considered. These practices especially hamper cross-cultural theory and measure development. New directions are proposed, centering on the relations between theory development, measurement, and application in the context of cultural variations. I conclude with a proposed strategy for local culture theory development. This strategy localizes measurement of theoretical constructs to adapt the theory to local cultural conditions, then localizes theory by indicating needed adjustments to the structure of theoretical linkages.     

Risk perception and victim perception: The judgment of HIV cases

There is a vast literature confirming that reactions to different risks are strongly affected by characteristics other than scientific risk estimates; most of this research has concentrated on mapping people's representations of sets of widely varying dangers (e.g. diseases, natural disasters, accidents). This study explored a potentially vital component of risk that cannot be studied by eliciting general reactions to many hazards: the extent to which who is at risk contributes to perceptions and judgments of a risk. While it may be preferable to assume that misfortunes affect the population uniformly, of course the truth is not so egalitarian. Thus, for both theoretical and policy reasons, it is worth exploring psychometrically representations of a particular risk as it affects different people. Using multidimensional scaling and hierarchical cluster analysis, we constructed models of respondents' representations of a disease assumed to be particularly affected by victim perception: Human Immunodeficiency Virus (HIV). Subjects rated the similarity of all possible pairs among 16 scenarios involving HIV infection; the scenarios contained information about both the victim and the method of contraction. A set of attribute scales as well as political/demographic information allowed us both to interpret the structures and to predict individual differences. The results confirmed that reactions to HIV infection are greatly affected by reactions to the victim. In particular, the perceived distastefulness and riskiness of the method of infection loomed larger than did either the overall likability of the victim or the general riskiness of the victim's behavior. Further, the salience of the most statistically influential dimension, ‘deservedness’, depended significantly on demographic and political characteristics of the respondents, suggesting that the relationship between personal values and risk perception is in part mediated by victim perception. Implications for risk perception work and public policy are discussed.     

Family‐Based HIV and Sexually Transmitted Infection Risk Reduction for Drug‐Involved Young Offenders: 42‐Month Outcomes

This study tested a family‐based human immunodeficiency virus (HIV)/sexually transmitted infection (STI) prevention approach integrated within an empirically supported treatment for drug‐involved young offenders, Multidimensional Family Therapy (MDFT). A randomized, controlled, two‐site community‐based trial was conducted with 154 youth and their parents. Drug‐involved adolescents were recruited in detention, randomly assigned to either MDFT or Enhanced Services as Usual (ESAU), and assessed at intake, 3, 6, 9, 18, 24, 36, and 42‐month follow‐ups. Youth in both conditions received structured HIV/STI prevention in detention and those in MDFT also received family‐based HIV/STI prevention as part of ongoing treatment following detention release. Youth in both conditions and sites significantly reduced rates of unprotected sex acts and STI incidence from intake to 9 months. They remained below baseline levels of STI incidence (10%) over the 42‐month follow‐up period. At Site A, adolescents who were sexually active at intake and received MDFT showed greater reduction in overall frequency of sexual acts and number of unprotected sexual acts than youth in ESAU between intake and 9‐month follow‐ups. These intervention differences were evident through the 42‐month follow‐up. Intervention effects were not found for STI incidence or unprotected sex acts at Site B. Intensive group‐based and family intervention in detention and following release may reduce sexual risk among substance‐involved young offenders, and a family‐based approach may enhance effects among those at highest risk. Site differences in intervention effects, study limitations, clinical implications, and future research directions are discussed.
