Research on contingency management is limited due to feasibility issues with monitoring adherence. Incentives usually depend on objective measures to verify compliance; therefore, biological markers for identifying alcohol use are not as dependable for the use of financial contingency studies. The Secure Continuous Remote Alcohol Monitor (SCRAM) is an objective alcohol biosensor that can be locked onto a person's ankle to address these limitations. In preparation for a large, contingency management study for HIV-positive and HIV-negative persons with heavy drinking, the aims for the study were to (1) explore barriers and facilitators to participating in a contingency management intervention using the SCRAM ankle monitor as the potential alcohol measure for the intervention; (2) explore levels of appropriate compensation for using the SCRAM and for study assessments as part of a contingency management intervention study; and (3) attitudes and beliefs on lifestyle changes as a consequence of wearing the SCRAM among HIV-positive and HIV-negative heavy drinkers in Florida. Five focus groups were conducted and we collected qualitative data from thirty-seven individuals (18 men; 19 women). During the analysis, six themes were identified as barriers and facilitators for participation in a contingency management intervention using the SCRAM sensor to measure alcohol use: (1) health assessment, (2) monetary incentives including payment structure and levels of compensation, (3) stigma associated with wearing the SCRAM sensor, (4) aesthetics and other related concerns with wearing the SCRAM sensor, (5) motivation to stop drinking, and (6) social support. Stigma was a major barrier for wearing the SCRAM sensor; however, if participants were motivated to change their behavior then the monetary incentives became a facilitator to wearing the sensor. In addition to the financial contingency method, social support may further increase the odds for participants to change their behaviors.

The purpose of this study was to examine neurological impairment in combination with information-motivation-behavioral skills (IMB) variables. The study tests the role of IMB variables as mediators of antecedent variables of demographics, life stress, social support, and neurological impairment with outcome measures of HIV preventive and risk behaviors in a sample of HIV-positive, alcohol-using adults (n = 250) with a history of alcohol abuse/dependence. Neurological impairment was measured with the Color Trails Test (CTT). Average performance on the CTT by the sample was substantially worse than established norms. In a directional latent variable model, neurological impairment directly predicted lower transmission knowledge scores and poorer performance on an observational condom skills assessment. Greater neurological impairment was significantly associated with greater age. Future interventions geared toward HIV+ adults who use alcohol should take into consideration HIV-related and age-related neurological functioning which may impede the facilitation of safe sex behaviors.

Sexual trauma is a national public health concern due to the alarming rates at which it occurs and decades of research supporting its long-term deleterious effects on health outcomes. We assessed the impact of gender norms and sexual trauma on power within sexual relationships among Latina immigrant farmworkers. At baseline, participants (N = 175) completed a survey examining demographic information, sexual trauma history, and gender norms; a follow-up was administered 6 months later. Past sexual trauma was associated with less power in sexual relationships, r = −.25, p < .001, as was endorsement of traditional Latina gender norms (i.e., marianismo): sexual relationship control, r = −.38, p < .001; sexual decision-making dominance, r = −.21, p = .005. In contrast, egalitarian gender norm endorsement was associated with higher levels of sexual relationship control, r = .37, p < .001, and sexual decision-making dominance, r = .17, p = .023. Gender norms moderated the association between sexual trauma and sexual relationship power. Specifically, women who subscribed more to marianismo and reported sexual trauma had less decision-making dominance in sexual relationships, whereas those with lower ratings of marianismo reported higher levels of decision-making dominance despite sexual trauma, R 2 = .03, p = .022. Sexual trauma history coupled with higher ratings of egalitarian gender norms was associated with higher levels of sexual relationship control, DR 2 = .02, p = .023. These results highlight the importance of culturally informed research to increase the sexual and overall health of vulnerable populations (e.g., Latina immigrant farmworkers).

BackgroundHIV-infected individuals continue to experience neurocognitive deterioration despite virologically successful treatments. The causes of neurocognitive impairment are still unclear. However, several factors have been suggested including the role of genetics. There is evidence suggesting that neurocognitive impairment is heritable and individual differences in cognition are strongly driven by genetic variations. The contribution of genetic variants affecting the metabolism and activity of dopamine may influence these individual differences.MethodsThe present study explored the relationship between two candidate genes (DRD4 and DRD2) and neurocognitive performance in HIV-infected adults. A total of 267 HIV-infected adults were genotyped for polymorphisms, DRD4 48 bp-variable number tandem repeat (VNTR), DRD2 rs6277 and ANKK1 rs1800497. The Short Category (SCT), Color Trail (CTT) and Rey-Osterrieth Complex Figure Tests (ROCT) were used to measure executive function and memory.ResultsResults showed significant associations with the SNP rs6277 and impaired executive function (odds ratio = 3.3, 95 % CI 1.2–2.6; p = 0.004) and cognitive flexibility (odds ratio = 1.6, 95 % CI 2.0–5.7; p = 0.001). The results were further stratified by race and sex and significant results were seen in males (odds ratio = 3.5, 95 % CI 1.5–5.5; p = 0.008) and in African Americans (odds ratio = 3.1, 95 % CI 2.3–3.5; p = 0.01). Also, DRD4 VNTR 7-allele was significantly associated with executive dysfunction.ConclusionThe study shows that genetically determined differences in the SNP rs6277 DRD2 gene and DRD4 48 bp VNTR may be risk factors for deficits in executive function and cognitive flexibility.

Serotonin reuptake variation is linked to a functional polymorphism in the promoter region of the SLC6A4 gene on chromosome 17. It is plausible that variations in genetically determined SLC6A4 activity may modify the risk of alcohol dependence. To determine whether this allele is associated with alcohol dependence, the authors conducted a systematic review and a metaanalysis. Twenty five studies with 8,885 participants were included. The meta-analysis was conducted using a random-effects model. Overall, the results did not support the association between alcohol dependence and SLC6A4 promoter polymorphism for the dominant, recessive . When effect modification was tested for gender, race/ethnicity, presence/absence of a psychiatric disorder, year of publication, and diagnostic criteria, none of the factors were significantly associated with alcohol dependence. The findings in this meta-analysis suggest that SLC6A4 promoter polymorphism is not associated with alcohol dependence.

In general Latinos hold more conservative attitudes regarding gender roles when compared to Whites. However, Latinos born in the United States with higher education are more likely to have egalitarian gender role attitudes compared to Latino immigrants. The aim of this study was to analyze the relationship between gender role attitudes and acculturation, marianismo, and relationship control, among Latina immigrants living in the United States. A hierarchical regression and correlation analysis were used to measure the outcome of this study. A total of 234 women were included in the study with a mean age of 34 years old. The education level was less than high school (53 percent), with the majority employed (54 percent). The average time living in the United States was 8 years (SD = 2.0). Acculturation, marianismo, and relationship control were significantly associated with gender‐role, R2 = .207, F (3, 95) = 11.3, p = 0.001. The correlation analysis showed an inverse relationship between egalitarian attitudes and marianismo (r = −.304, p < .0005) and a positive relationship with acculturation (r = .295, p < .0005). Egalitarian gender role attitudes were observed with an inverse bidirectional relationship between marianismo and acculturation among Latino immigrant women living in the United States.

HIV-infected individuals continue to experience neurocognitive deterioration despite virologically successful treatments. While the cause remains unclear, evidence suggests that HIV-associated neurocognitive disorders (HAND) may be associated with neurobehavioral dysfunction. Genetic variants have been explored to identify risk markers to determine neuropathogenesis of neurocognitive deterioration. Memory deficits and executive dysfunction are highly prevalent among HIV-infected adults. These conditions can affect their quality of life and HIV risk-taking behaviors. Single nucleotide polymorphisms in the SLC6A4, TPH2, and GALM genes may affect the activity of serotonin and increase the risk of HAND. The present study explored the relationship between SLC6A4, TPH2, and GALM genes and neurocognitive impairment in HIV-infected alcohol abusers. A total of 267 individuals were genotyped for polymorphisms in SLC6A4 5-HTTLPR, TPH2 rs4570625, and GALM rs6741892. To assess neurocognitive functions, the Short Category and the Auditory Verbal Learning Tests were used. TPH2 SNP rs4570625 showed a significant association with executive function in African American males (odds ratio 4.8, 95% CI, 1.5–14.8; P = 0.005). Similarly, GALM SNP rs6741892 showed an increased risk with African American males (odds ratio 2.4, 95% CI, 1.2–4.9; P = 0.02). This study suggests that TPH2 rs4570625 and GALM rs6741892 polymorphisms may be risk factors for HAND.
