Drug use and sexual risk among gay and bisexual men who frequent party venues.

Research connecting club drug use to risky sex among gay/bisexual men (GBM) contains methodological issues that have limited knowledge about the relative risks of distinct drugs. This paper reports drug use and sexual behavior data from 197 GBM who frequented at least one party venue within 3 months of participating. Alarming rates of drug use and unprotected anal intercourse (UAI) with casual sex-partners were reported in connection with time spent at a bar, club or circuit party. Structural equation modeling revealed that use of methamphetamine, gammahydroxybutrate (GHB), and/or ketamine (K), but not use of ecstasy, at a party venue helped explain likelihood of UAI with a casual sex-partner while under the influence of a drug during/following time partying (ß = 0.41, p < .01). Findings suggest use of methamphetamine, GHB and/or K at party venues increases risk for subsequent UAI with casual sex-partners. Study implications, limitations, and recommendations for future research are discussed.

Body dissatisfaction and methamphetamine use among HIV-positive gay and bisexual men: a pilot study.

Methamphetamine use is strongly associated with risky sex and increased reports of HIV and other sexually transmitted infections among gay and bisexual men (GBM) who attend dance/circuit parties. The psychological mechanisms underlying methamphetamine use in this subculture, however, remain unclear. These exploratory findings are from a 2004 dataset measuring body dissatisfaction and drug use among 42 HIV-positive GBM in South Florida who attended at least one bar/club/circuit party within 3 months of participating. A multivariate regression model revealed that body dissatisfaction accounted for a small but significant amount of variance in methamphetamine use. Treatment implications and recommendations for future research are discussed.

Men's serostatus disclosure to parents: associations among social support, ethnicity, and disease status in men living with HIV.

BACKGROUND: Directly disclosing a positive HIV serostatus to family members can affect psychological and disease status. Perceptions that one is in a supportive family environment may moderate these effects; however, ethnic differences may exist in the support processes of families coping with HIV. METHODS: We examined the role of serostatus disclosure to parents, HIV-specific family support, and ethnicity (Latino versus non-Hispanic White) in explaining disease status (HIV Viral Load, CD4+ cell count) in a sample of men living with HIV (MLWH). Men (n=120) reported whether they had disclosed their serostatus to their mothers and fathers, rated their perceptions of HIV-specific social support received from family members, and provided morning peripheral venous blood samples to assess immune function. We also collected psychosocial and urinary neuroendocrine indicators of stress/distress as possible mediator variables. RESULTS: A three-way interaction emerged between serostatus disclosure to mothers, HIV-specific family support, and ethnicity in explaining both viral load and CD4+ cell count. Non-Hispanic White men who had disclosed to mothers and were receiving high family support had a lower viral load and higher CD4+ cell count, but Latino men who had disclosed to mothers and were receiving low family support had a higher viral load. These associations were not accounted for by men's medication adherence, psychological distress, or neuroendocrine hormones. Disclosure to fathers was not related to disease status. CONCLUSIONS: The effects of serostatus disclosure on disease status may depend, in part, on ethnic differences in the interpersonal processes of men's close family relationships.

Latinos and HIV/AIDS: examining factors related to disparity and identifying opportunities for psychosocial intervention research.

Latinos maintain an AIDS case rate more than 3 times higher than whites, a greater rate of progression to AIDS, and a higher rate of HIV/AIDS-related deaths. Three broad areas are reviewed related to these disparities: (1) relevant demographic, socioeconomic, and socio-cultural factors among Latinos; (2) drug abuse and mental health problems in Latinos relevant to HIV/AIDS outcomes; and (3) opportunities for psychosocial intervention. Latinos living with HIV are a rapidly growing group, are more severely impacted by HIV than whites, and confront unique challenges in coping with HIV/AIDS. A body of research suggests that depression, substance abuse, treatment adherence, health literacy, and access to healthcare may be fruitful targets for intervention research in this population. Though limited, the current literature suggests that psychosocial interventions that target these factors could help reduce HIV/AIDS disparities between Latinos and whites and could have important public health value.

Physical symptoms, beliefs about medications, negative mood, and long-term HIV medication adherence.

BACKGROUND: Near-perfect levels of HIV medication adherence are necessary for treatment to be successful. However, many patients continue to report nonadherence to HIV treatment. PURPOSE: This study examines the relationship between symptoms of HIV and medication adherence and evaluates beliefs about HIV medications and negative mood states as potential mediators of this relationship. METHODS: These relationships were tested with structural equation modeling using a 15-month longitudinal design. The ethnically diverse convenience sample included 325 HIV-infected men who have sex with men and women prescribed Highly Active Antiretroviral Therapy (HAART). RESULTS: Results showed that a greater number of symptoms were associated with poorer medication adherence, and this relationship was partially mediated by increases in concerns about HAART. Contrary to expectations, negative mood states were not directly related to medication adherence. In the final model, concerns about HAART and general distrust of medications each predicted poorer HAART adherence. Necessity beliefs about HAART and level of educational attainment each predicted better adherence. The final model accounted for approximately 24% of the variance in HAART adherence. CONCLUSIONS: The results of this study suggest that Horne's (1) necessity-concerns framework can be successfully applied to identify beliefs about medication that are important predictors of adherence to HAART over time. These findings have relevance for developing interventions to improve medication adherence among HIV-infected patients.

A measurement model of medication adherence to highly active antiretroviral therapy and its relation to viral load in HIV-positive adults.

This study compared a multiple method measurement model of highly active antiretroviral therapy (HAART) adherence with single-method models to determine optimal validity in predicting HIV viral load. Repeated measures of antiretroviral adherence were collected over a 15-month period using three different measurement methods: a self-report questionnaire, an adherence interview item, and electronic medication monitoring. The participants included HIV-positive men and women (n = 323) who were currently prescribed HAART. Single-factor models composed of multiple measurements over time were developed for each adherence method and HIV viral load. The three adherence methods were then combined in a second order factor measurement model. Structural equation modeling was used to test the models. Mean adherence, defined as percent of doses taken, was 92%, 90%, and 57% by self-report, interview, and electronic monitoring, respectively. Reliability of individual measurements of adherence was low. Four or seven assessments were needed to attain acceptable stability, depending on the method. The second-order factor model of adherence fit the data and explained 45% of the variability in HIV viral load. Models including only one method of assessing adherence explained between 20% and 24% of the variability. Models that included both self-report and electronic monitoring optimized predictive validity. Using at least two different methods of adherence measurement, each assessed at multiple times is recommended to derive reliable and valid measurement of medication adherence, which is predictive of biological outcomes such as HIV viral load.

A path model of the effects of spirituality on depressive symptoms and 24-h urinary-free cortisol in HIV-positive persons.

OBJECTIVE: The present investigation examined the associations among spirituality, positive reappraisal coping, and benefit finding as they relate to depressive symptoms and 24-h urinary-free-cortisol output. METHODS: Following an initial screening appointment, 264 human-immunodeficiency-virus-positive men and women on highly active antiretroviral therapy provided 24-h urine samples and completed a battery of psychosocial measures. RESULTS: Spirituality was associated with higher positive reappraisal coping and greater benefit finding. Benefit finding and positive reappraisal coping scores were, in turn, both related to lower depressive symptoms. Finally, we determined that benefit finding was uniquely predictive of decreased 24-h urinary-free cortisol output. CONCLUSION: Positive reappraisal coping and benefit finding may co-mediate the effect of spirituality on depressive symptoms, and benefit finding may uniquely explain the effect of spirituality on 24-h cortisol output.

Reductions in depressed mood and denial coping during cognitive behavioral stress management with HIV-Positive gay men treated with HAART.

BACKGROUND: Stress management interventions for HIV-positive persons have been designed to enhance coping skills and encourage health-promoting behaviors with the hope of decreasing distress and slowing disease progression. PURPOSE: We examined the efficacy of a cognitive behavioral stress management (CBSM) intervention in combination with medication adherence training (MAT) in 130 gay and bisexual men living with HIV infection. METHODS: Participants were randomized to either a 10-week CBSM+MAT intervention (n = 76) or a MAT-only condition (n = 54). Measures of self-reported adherence, active cognitive coping (i.e., acceptance and positive reinterpretation), avoidant coping (i.e., denial and behavioral disengagement), and depressed mood were examined over the 10-week intervention period. RESULTS: Men in CBSM+MAT reported reductions in depressed mood and denial coping during the 10-week intervention period, but no changes in active cognitive coping or self-reported adherence were observed. Using path analysis, greater reliance on denial coping at baseline was associated with decreased depressed mood at 10 weeks. We also determined that CBSM+MAT may decrease depressed mood by reducing reliance on denial coping over the 10-week intervention period. CONCLUSIONS: Although denial may be an effective means of distress reduction in the short term, reliance on this coping strategy may result in a decreased capacity to effectively manage a variety of disease-related stressors in the long term. CBSM+MAT addresses this potentially detrimental pattern by teaching stress reduction skills that may decrease depressed mood via reduced reliance on denial coping.

Randomized clinical trial of cognitive behavioral stress management on human immunodeficiency virus viral load in gay men treated with highly active antiretroviral therapy.

OBJECTIVE: Human Immunodeficiency Virus (HIV)-positive individuals treated with highly active antiretroviral therapy (HAART) may experience psychological burdens and negative mood states, which could impair their ability to derive maximum benefits from their medical treatment. We tested whether a cognitive behavioral stress management (CBSM) intervention in combination with antiretroviral medication adherence training (MAT) from a clinical pharmacist influences HIV viral load more than MAT alone. METHODS: HIV-positive men who have sex with men were randomized to either a 10-week CBSM + MAT intervention (n = 76) or a MAT-Only condition (n = 54). Data were collected at baseline immediately following the 10-week intervention period, at 9 months postrandomization, and at 15 months postrandomization. RESULTS: We found no differences in HIV viral load among the 130 men randomized. However, in the 101 men with detectable viral load at baseline, those randomized to CBSM + MAT (n = 61) displayed reductions of 0.56 log10 units in HIV viral load over a 15-month period after controlling for medication adherence. Men in the MAT-Only condition (n = 40) showed no change. Decreases in depressed mood during the intervention period explained the effect of CBSM + MAT on HIV viral load reduction over the 15 months. CONCLUSIONS: A time-limited CBSM + MAT intervention that modulates depressed mood may enhance the effects of HAART on suppression of HIV viral load in HIV+ men with detectable plasma levels.

Psychosocial responses to treatment for breast cancer among lesbian and heterosexual women.

This study compared the experiences of 39 self-identified lesbians and 39 heterosexual women who had recently been treated for breast cancer. They were matched by age, stage of disease, time since diagnosis, and ethnicity. Data were collected by a questionnaire completed at home and returned by mail. Variables assessed included emotional adjustment, thought intrusion and avoidance, perceived quality of life, concerns about breast cancer, benefit finding, relationship and sexual disruption, psychosexual adjustment, social support, and coping. Compared to the heterosexual women, lesbians reported less thought avoidance, lower levels of sexual concern, less concern about their appearance, and less disruption in sexual activity, but also substantially lower perceptions of benefit from having had cancer. Lesbians reported less social connection to family, but no group difference emerged in connection to friends. Lesbians reported less denial coping, and more use of support from friends, more venting, and more positive reframing. Better understanding of the similarities and differences between groups will help address the relevant clinical issues appropriately, in order to optimize psychosocial adjustment to breast cancer. .

A stress and coping model of medication adherence and viral load in HIV-positive men and women on highly active antiretroviral therapy (HAART).

The authors tested a structural model that incorporated age, time since diagnosis, social support, coping, and negative mood as predictors of medication adherence and HIV viral load on 188 men and 134 women on highly active antiretroviral therapy (HAART). The authors used psychosocial latent factors formed from baseline measures to predict latent factors of adherence, as assessed by electronic monitoring and self-report, and viral load defined by indicators assessed over a 15-month period. Results from the model indicate that greater negative mood and lower social support are related to greater use of avoidance-oriented coping strategies. Use of these coping strategies by patients on HAART is related to poorer medication adherence and, subsequently, higher viral load. This model advances researchers' understanding of the contribution of psychosocial variables in predicting treatment adherence and disease progression in HIV-positive men and women.

Development and implementation of a medication adherence training instrument for persons living with HIV: the MATI.

Recent advances in the medical management of HIV offer the potential for increased longevity, improved quality of life, and the treatment of HIV as a chronic, rather than terminal, illness. The advent of highly active antiretroviral therapy (HAART) has required the necessity of strict adherence to complex medication regimens. As a vital factor in the successful outcome of HAART therapy, adherence-focused treatment represents a teaching opportunity for practitioners involved in the care and management of persons who are HIV positive. Scores of articles have been published regarding nonadherence, and numerous strategies have been employed to encourage adherence. Despite these efforts, medication adherence continues to present problems for patients and health care providers. This article discusses prior and existing adherence interventions for people living with HIV and outlines the rationale related to the development of a structured protocol, the Medication Adherence Training Instrument (MATI), for the evaluation and enhancement of HIV medication adherence by health care providers. The key components to the MATI throughout all sessions are to provide information, enhance motivation, and assess current levels of adherence and HIV-related knowledge.

Repression and high anxiety are associated with aberrant diurnal cortisol rhythms in women with metastatic breast cancer.

Previous research has provided evidence of autonomic, endocrine, and immunological dysregulation in repressers and a possible association with cancer incidence and progression. Recently published data from the authors' laboratory demonstrated that flatter diurnal cortisol slopes were a risk factor for early mortality in women with metastatic breast cancer. In the current analysis of this same sample (N=91), the authors tested differences at baseline between groups scored using the Weinberger Adjustment Inventory on diurnal cortisol slope and mean cortisol levels. When compared with self-assured and nonextreme groups, the represser and high-anxious groups had a significantly flatter diurnal slope. Diurnal slope was similar for repressers and high-anxious groups. Groups did not differ on mean cortisol levels, nor did they differ on intercept (morning) values.

Intimacy and sexual behavior among HIV-positive men-who-have-sex-with-men in primary relationships.

Unprotected anal intercourse among men-who-have-sex-with-men (MSM) occurs more frequently between partners in a primary relationship than between nonprimary partners. Although research supports the role of social support in risky sex, findings also suggest that the reasons associated with risky sex differ depending on both the relationship status and HIV-serostatus of MSM. This study assessed whether level of intimacy within a primary relationship helps to explain risky sex among a sample of 78 HIV-positive MSM currently involved in a primary relationship. Findings suggest that both drug use prior to sex and HIV status of the primary partner moderate the relationship between intimacy and sexual risk behaviors. Under levels of low drug use, greater intimacy functioned as a protective factor within seroconcordant relationships whereas it functioned as a risk factor within serodiscordant relationships. Implications for educational and clinical interventions are discussed.

Social support, positive states of mind, and HIV treatment adherence in men and women living with HIV/AIDS.

Numerous studies have linked social support to better medication adherence among illness groups, but few have examined potential mechanisms for this relationship. Relationships were examined between social support, depression, positive states of mind (PSOM), and medication adherence among HIV positive men who have sex with men (n = 61) and women (n = 29) on highly active antiretroviral therapy. Depression and PSOM were evaluated as potential mediators of the relationship between support and adherence. Cross-sectional data showed that greater social support and PSOM related to better adherence whereas higher depression scores related to nonadherence. PSOM partially mediated the relationship between social support and adherence. PSOM may be an important mechanism through which social support is related to better medication adherence in this population.

Perceived stress mediates the effects of coping on the quality of life of HIV-positive women on highly active antiretroviral therapy.

This study examined the relationship between three HIV-specific coping strategies (cognitive coping strategies, denial, and religious coping) and quality of life (QoL) in 90 HIV+, predominately minority women on highly active antiretroviral therapy. Religious coping was unrelated to QoL; however, use of cognitive coping strategies was related to greater QoL, and denial was related to poorer QoL. Baron and Kenny's model of mediation was then used to test perceived stress as a mediator of the relationships between denial and cognitive coping strategies and QoL. These relationships were both mediated by perceived stress. Results suggest that utilization of certain coping strategies may lessen or heighten perceptions of life stressfulness, thereby influencing QoL in this understudied population.

John Henry Active Coping, education, and blood pressure among urban blacks.

The John Henryism hypothesis posits that individuals who actively cope with psychosocial stressors in the face of low socioeconomic resources are more likely to exhibit higher blood pressure levels than those with greater socioeconomic resources. It has been proposed that John Henryism may contribute to the disproportionately high rates of hypertension among blacks. Previous studies which support the John Henryism hypothesis have been conducted among blacks who reside in primarily southern rural settings. However, more recent studies conducted among urban blacks, have yielded contrasting results. This study examined the John Henryism hypothesis in a middle-aged urban sample of blacks in south Florida. The results of the study confirmed that there is indeed a relationship among John Henry Active Coping, years of education, and blood pressure among urban blacks in south Florida. Upon closer examination, higher John Henry Active Coping scores were associated with higher systolic and diastolic blood pressure among higher educated men, and John Henry Active Coping scores were associated with higher systolic and diastolic blood pressure among women with lower levels of education. The findings are discussed in terms of sociocultural factors that may influence the coping styles of black men and women in different communities and environments.

Assessing the reliability and validity of the John Henry Active Coping Scale in an urban sample of African Americans and white Americans.

OBJECTIVES: The primary focus of this study was to examine the psychometric properties of the John Henry Active Coping scale (JHAC12) among an urban middle-aged sample of African Americans and white Americans. DESIGN: The sample consisted of 75 African Americans and 129 white Americans from South Florida ranging in age from 25 to 54 years. Subjects completed the JHAC12, the Life Orientation Test (LOT), Coping Orientation to Problems Encountered (COPE) subscales, and the Marlowe-Crowne Social Desirability scale. RESULTS: Major findings supported the validity and reliability of the JHAC12 among both African Americans and white Americans. For both the African American and white American subsamples, the JHAC12 was correlated with the active coping and suppression of competing activities subscales of the COPE and negatively correlated with the Marlowe-Crowne Social Desirability scale. In the African American subsample the JHAC12 was positively correlated with the LOT. The JHAC12 was also negatively associated with the behavioral disengagement subscale of the COPE among white Americans. Multiple regression analyses revealed that the proportion of variance in the JHAC12 explained by the various subscales of the COPE, Marlowe-Crowne, and the LOT was 43% for African Americans and 20% for white Americans. Factor analyses suggested two similar and meaningful factors among the African American and white American subsamples. Finally, Cronbach alpha reliabilities revealed similar subsample coefficients. DISCUSSION: The implications of the findings are discussed in terms of the JHAC12's ability to assess the construct of active coping among African Americans and white Americans.

Life stress and cervical squamous intraepithelial lesions in women with human papillomavirus and human immunodeficiency virus.

OBJECTIVE: Human immunodeficiency virus (HIV)-infected women are at risk for cervical intraepithelial neoplasia (CIN) and cancer due to impaired immunosurveillance over human papillomavirus (HPV) infection. Life stress has been implicated in immune decrements in HIV-infected individuals and therefore may contribute to CIN progression over time. The purpose of this study was to determine whether life stress was associated with progression and/or persistence of squamous intraepithelial lesions (SIL), the cytologic diagnosis conferred by Papanicolaou smear, after 1-year follow-up among women co-infected with HIV and HPV. METHOD: Thirty-two HIV-infected African-American and Caribbean-American women underwent a psychosocial interview, blood draw, colposcopy, and HPV cervical swab at study entry. Using medical chart review, we then abstracted SIL diagnoses at study entry and after 1-year follow-up. RESULTS: Hierarchical logistic regression analysis revealed that higher life stress increased the odds of developing progressive/persistent SIL over 1 year by approximately seven-fold after covarying relevant biological and behavioral control variables. CONCLUSIONS: These findings suggest that life stress may constitute an independent risk factor for SIL progression and/or persistence in HIV-infected women. Stress management interventions may decrease risk for SIL progression/persistence in women living with HIV.

Stress as a predictor of symptomatic genital herpes virus recurrence in women with human immunodeficiency virus.

OBJECTIVE: Genital herpes (Herpes Simplex Virus Type 2, HSV-2) is a significant public health problem for HIV+ women, who have high rates of HSV-2 seropositivity and elevated risk for HSV-2 associated morbidity and mortality. Life stress has been identified as a co-factor in genital herpes recurrence. However, no research has evaluated the relationship between stress and genital herpes recurrences in HIV+ women. The purpose of this study was to determine whether stress was associated with symptomatic genital herpes recurrences in women seropositive for HIV and HSV-2. METHODS: Thirty-four HIV-infected African-American and Caribbean-American women underwent a psychosocial interview, blood draw and gynecologic examination to assess gynecologic symptoms (including genital herpes) at study entry. Life stress was measured using a 10-item modified version of the Life Experiences Survey (LES). Genital herpes recurrence over 1-year follow-up was abstracted using medical chart review. RESULTS: Using hierarchical linear regression analysis, life stress at study entry was significantly associated with number of genital herpes recurrences during 1-year follow-up (beta=.38, P=.03) after controlling for HIV disease variables and relevant behavioral factors. Recent life stress, in particular, was highly predictive of genital herpes recurrence during follow-up (beta=.57, P=.002). The relationship between life stress and genital herpes recurrence persisted after controlling for HSV-2 viral reactivation (i.e., HSV-2 IgG titers) at study entry. CONCLUSION: These findings suggest that stress may be a significant predictor of genital herpes recurrence in women with HIV and HSV-2. Stress management interventions may buffer HSV-related morbidity and mortality in women with HIV.
