Professional overview

Dr. Stephanie Cook’s overarching research focus is to understand how structural- and individual-level minority stressors contribute to mental health, physical health, and health behaviors across the life span. Further, she seeks to understand how features of close relationships can exacerbate or buffer the negative effects of minority stress on health. Her work primarily focuses on young adults transitioning to adulthood who are at the intersection of racial/ethnic and sexual orientation status. In addition, much of her current work examines the links between minority stress (i.e., daily experiences of discrimination) and biological markers of stress (e.g. cortisol and c-reactive protein).
Dr. Cook’s substantive methodological and statistical focus is in the development and application of longitudinal study designs (i.e., intensive longitudinal designs) for determining the ways in which dynamic changes in features of minority stress (e.g., daily and momentary discrimination events) are associated with changes in risk behaviors and physical health (e.g., sexual risk and substance use, pre-clinical cardiovascular disease, and biological stress) among racial/ethnic and/or sexual minority young adults.
Dr. Cook is the Director of the Attachment and Health Disparities Research Lab (AHDL) which is currently made up of about 20 undergraduate, graduate, and postdoctoral fellows. She developed an integrated theory of adult attachment (the Integrated Attachment and Sexual Minority Stress Model [IASMS]; i.e., the development, or lack, of strong socio-emotional bonds) and minority stress (i.e., social stress experienced by individuals in minority social groups) as a means to better understand and address the health needs of disadvantaged youth transitioning to adulthood. Dr. Cook and her team’s long-term goal is to continue creating, implementing, and refining sustainable interventions to reduce the influence of stress on health utilizing innovative methodologies.

1883-1887AbstractMen who have sex with men (MSM) make up nearly half of all people living with HIV in the United States. The prevalence of the epidemic in this population makes it vitally important to understand the transmission of the infection and to develop methods to prevent its spread. The current study uses longitudinal diary methods to examine relationships between substance use and unprotected anal intercourse in a sample of 158 HIV-positive, mostly ethnic minority MSM. Results indicate that both general substance use and use of specific drugs (i.e., inhalants, cocaine, crack, and club drugs) have a substantial impact on the sexual risk behavior of this population.Deficits in dopamine D 2 receptors and presynaptic dopamine in heroin dependence: Commonalities and differences with other types of addiction

192-198AbstractPositron emission tomography (PET) imaging studies have shown that addiction to a number of substances of abuse is associated with a decrease in dopamine D 2/3 receptor binding and decreased presynaptic dopamine release in the striatum. Some studies have also shown that these reductions are associated with the severity of addiction. For example, in cocaine dependence, low dopamine release is associated with the choice to self-administer cocaine. The goal of the present study was to investigate these parameters of striatal dopamine transmission in heroin dependence and their association with drug seeking behavior. Heroin-dependent and healthy control subjects were scanned with [ 11C]raclopride before and after stimulant administration (methylphenidate) to measure striatal D 2/3 receptor binding and presynaptic dopamine release. After the PET scans, the heroin-dependent subjects performed heroin self-administration sessions. Both striatal D 2/3 receptor binding and dopamine release were reduced in the heroin-dependent subjects compared with healthy control subjects. However, neither PET measure of dopamine transmission predicted the choice to self-administer heroin. These findings show that heroin addiction, like addiction to other drugs of abuse, is associated with low D 2/3 receptor binding and low presynaptic dopamine. However, neither of these outcome measures was associated with the choice to self-administer heroin.Intimate-partner violence and HIV in South African women

506-508AbstractBackground: Men with HIV who have sex with men (MSM) represent the largest group of people living with HIV/AIDS in the United States. It is important to understand the sexual risk-taking behaviours that may be linked to the transmission of HIV and other sexually transmitted infections in this population. Models of HIV risk that focus solely on personal factors have been demonstrated to be ineffective at explaining risk behaviour. Rather, in order to fully understand sexual risktaking, it is important to examine the factors linked to high-risk sexual situations and not solely the factors linked to potentially high-risk people. Methods: A diverse sample of 100 MSM with HIV completed a 6-week internet-based sex diary that collected detailed information on recent sexual encounters. In total, information on over 250 sexual episodes was collected and analysed. Generalised linear mixed models were used to examine situational predictors of risk episodes. Results: Analyses revealed that drug use by self and sex partners (examined individually and together) were positively related to risk episodes. Likewise, having a sex partner met online and having a sexual encounter in a sex party or bathhouse setting was linked to risk episodes. Sexual episodes that involved a sex-partner who was perceived as sexually desirable and those involving communication about HIV and/or condom use with partners each were negatively related to risk. Conclusions: Situational factors play an important role in explaining sexual risk-taking among MSM with HIV. Researchers should place a greater focus on drug use and characteristics of sex partners and settings in which sexual behaviours occur as situational predictors of risk in order to comprehensively understand sexual risk-taking in this population.
