RESUMO

BACKGROUND: COVID-19 and efforts to manage widespread infection may compromise HIV care engagement. The COVID-19-related factors linked to reduced HIV engagement have not been assessed among postpartum women with HIV, who are at heightened risk of attrition under non-pandemic circumstances. To mitigate the effects of the pandemic on care engagement and to prepare for future public health crises, it is critical to understand how COVID-19 has impacted (1) engagement in care and (2) factors that may act as barriers to care engagement. METHODS: A quantitative assessment of COVID-19-related experiences was added to a longitudinal cohort study assessing predictors of postpartum attrition from HIV care among women in South Africa. Participants (N = 266) completed the assessment at 6, 12, 18, or 24 months postpartum between June and November of 2020. Those who endorsed one or more challenge related to engagement in care (making or keeping HIV care appointments, procuring HIV medications, procuring contraception, and/or accessing immunization services for infants; n = 55) were invited to complete a brief qualitative interview, which explored the specific factors driving these challenges, as well as other impacts of COVID-19 on care engagement. Within this subset, 53 participants completed an interview; qualitative data were analyzed via rapid analysis. RESULTS: Participants described key challenges that reduced their engagement in HIV care and identified four other domains of COVID-19-related impacts: physical health, mental health, relationship with a partner or with the father of the baby, and motherhood/caring for the new baby. Within these domains, specific themes and subthemes emerged, with some positive impacts of COVID-19 also reported (e.g., increased quality time, improved communication with partner, HIV disclosure). Coping strategies for COVID-19-related challenges (e.g., acceptance, spirituality, distraction) were also discussed. CONCLUSIONS: About one in five participants reported challenges accessing HIV care, medications, or services, and they faced complex, multilayered barriers to remaining engaged. Physical health, mental health, relationships with partners, and ability to care for their infant were also affected. Given the dynamic nature of the pandemic and general uncertainty about its course, ongoing assessment of pandemic-related challenges among postpartum women is needed to avoid HIV care disruptions and to support wellbeing.

RESUMO

Posttraumatic stress disorder (PTSD) symptoms may interfere with gay, bisexual and other men who have sex with men's (MSM) ability to engage in safe sex practices. An indirect relationship with dissociation may help to elucidate the relationship between PTSD symptom severity and condomless sex among MSM with childhood sexual abuse (CSA) histories. These relationships have not previously been examined in this group, which has a unique vulnerability for HIV acquisition. A cross-sectional sample of MSM with histories of CSA (N=290) was recruited at study sites in Boston, MA, and Miami, FL. Participants had a mean age of 37.95 years (SD=11.68), 22% were African American and 29.4% identified as Latino. The sample reported a mean of 10.47 (SD=4.38) lifetime PTSD symptoms and 26.4% met the clinical threshold for dissociation. Logistic regression models (adjusted for age, education, and substance use disorder) were used to assess indirect effects of dissociation on the relationship between lifetime PTSD symptoms and condomless anal/vaginal sex episodes with serodiscordant or unknown status partners in the past 3 months. Dissociation accounted for the association between lifetime PTSD symptom severity and condomless sex episodes. The Sobel test (Sobel = 2.04, p= .042; CI 95% bias-corrected bootstrap) suggested significant indirect effects for dissociation. Dissociation among MSM with CSA histories may compromise accurate appraisals of sexual risk and safety and increase vulnerability for HIV acquisition. Further research is warranted to address HIV prevention in the context of PTSD symptom severity to improve the mental health of MSM and increase the effectiveness of HIV prevention interventions.

RESUMO

To address childhood sexual abuse (CSA) related distress and HIV risk in men who have sex with men (MSM) using cognitive-behavioral therapy for trauma and self-care (CBT-TSC), which is a novel intervention integrating HIV risk reduction with modified cognitive and behavioral therapy strategies for post-traumatic stress. We compared CBT-TSC to HIV voluntary counseling and testing (VCT)-only in an initial 2-arm RCT in 43 HIV-negative MSM at with a history of CSA and HIV risk. Serodiscordant condomless anal/vaginal sex (CAS; CAS with HIV-postive or HIV unknown status partners) and posttraumatic stress disorder (PTSD) symptoms (Davidson Trauma Scale: total score and avoidance, intrusions, hyperarousal subscales) were outcomes immediately post-treatment, and at 6- and 9-month follow-up. At post-treatment, CBT-TSC had decreased odds (approximately 60%) of any CAS and greater reductions in CAS compared to VCT-only. Additionally, the CBT-TSC condition experienced greater reductions in total PTSD and avoidance symptoms. At the follow-up visits, CBT-TSC condition had significant reductions in the odds of any CAS and reductions in CAS. However, for PTSD symptoms, only the avoidance subscale remained significantly different compared to VCT-only. CBT-TSC is a potentially efficacious approach to address HIV risk in MSM with a CSA history, with replication and extension in a larger trial needed. This proof-of-concept trial is the first to integrate the treatment of a commonly occurring mental-health syndemic problem in MSM with a health psychology approach to self-care in MSM.Trial Registration Clinicaltrials.gov NCT01266122.

RESUMO

BACKGROUND: Despite antiretroviral treatment (ART) being an efficacious treatment for HIV, essentially making it a chronic non-terminal illness, two related and frequent concerns for many people living with HIV/AIDS (PLWHA) continue to be HIV-related stigma and life stress. These two variables are frequently associated with depression, substance use, and poorer functional health. Studies to date have not fully examined the degree to which these constructs may be associated within one model, which could reveal a more nuanced understanding of how HIV-related stigma and life stress affect functional health in PLWHA. METHODS: The current study employed hybrid structural equation modeling to examine the interconnectedness and potential indirect relationships of HIV-related stigma and life stress to worse health through substance use and depression, controlling for ART adherence and age. Participants were 240 HIV-infected individuals who completed a biopsychosocial assessment battery upon screening for an RCT on treating depression in those infected with HIV. RESULTS: Both HIV-related stigma and stressful life events were directly related to depression, and depression was directly related to health. There were significant indirect effects from stigma and stress to health via depression. There were no significant effects involving substance use. CONCLUSION: It is important to continue to develop ways to address stigma, stressful life events, and their effects on distress in those living with HIV. Expanding our knowledge of disease progression risk factors beyond ART adherence is important to be able to design adjuvant interventions, particularly because treatment means that people living with HIV have markedly improved life expectancy and that successful treatment means that HIV is not transmittable to others.

RESUMO

BACKGROUND: This study examined whether a culturally focused psychiatric consultation program (CFP) for Latino Americans was equally effective in reducing depressive symptoms in English-speaking and Spanish-speaking patients. METHODS: The CFP utilizes the Engagement Interview Protocol (EIP), a semi-standardized protocol eliciting patient narratives about illness beliefs. The sample included 118 Latino American patients presenting with depressive symptoms. Patient-preferred primary language was examined as a moderator for the effect of CFP participation vs usual care on change in depressive symptoms. RESULTS: Multiple regression analysis revealed that the interaction effect of primary language and treatment arm on depressive symptoms, as measured by the Quick Inventory of Depressive Symptomatology-Self Report was not statistically significant at 6-month follow-up (B = -2.89, t = -1.35, P = .180). CONCLUSIONS: The findings suggest that the CFP was equally effective in both Spanish and English-speaking Latino Americans. The trend in the results toward greater reduction in depressive symptoms in primary Spanish-speaking Latino Americans as compared with primary English-speaking Latino Americans suggests the importance of receiving language-concordant care.

RESUMO

BACKGROUND: Men who have sex with men (MSM) in India are a key group at risk for HIV acquisition and transmission. They are also an extremely marginalized and stigmatized population, facing immense psychosocial stressors including, but not limited to, stigma, homophobia, discrimination, criminalization, low self-esteem, low self-acceptance, distress, and, as a result, high rates of mental health problems. Although these multi-level psychosocial problems may put MSM at high risk for HIV acquisition and transmission, currently HIV prevention interventions in India do not address them. This paper describes the design of a psychosocial intervention to reduce HIV risk for MSM in India. METHODS: Funded by the National Institute of Mental Health, this study is a two-arm randomized clinical efficacy trial of a self-acceptance based psychosocial HIV prevention intervention, informed by the minority stress model and syndemic theory, that was developed with extensive community-based formative work and input from the Indian MSM community and key informants who are knowledgeable about the experiences faced by MSM in India. Participants are MSM in Chennai and Mumbai who endorsed recent sexual behaviors placing them at high risk for HIV/sexually transmitted infection (STI) acquisition and transmission. Enrolled participants are equally randomized to either 1) the experimental condition, which consists of four group and six individual counseling sessions and includes standard of care HIV/STI testing and counseling, or 2) the standard of care condition, which includes HIV/STI testing and counseling alone. The primary outcomes are changes in the frequency of condomless anal sex acts and STI incidence (syphilis seropositivity and urethral, rectal, and pharyngeal gonorrhea and chlamydia infection. Major study assessment visits occur at baseline, 4-, 8-, and 12-months. DISCUSSION: HIV prevention interventions that address the psychosocial stressors faced by MSM in India are needed; this study will examine the efficacy of such an intervention. If the intervention is successful, it may be able to reduce the national HIV/AIDS burden in India while empowering a marginalized and highly stigmatized group.

RESUMO

BACKGROUND: Positive psychological constructs have been associated with reduced suicidal ideation, and interventions to cultivate positive feelings have the potential to reduce suicide risk. This study compares the efficacy of a 6-week, telephone-based positive psychology (PP) intervention against a cognition-focused (CF) control intervention among patients recently hospitalized for depression and suicidal ideation or behavior. METHOD: A total of 65 adults with a current major depressive episode reporting suicidal ideation or a recent suicide attempt were enrolled from participating in-patient psychiatric units. Prior to discharge, participants were randomized to the PP (n = 32) or CF (n = 33) intervention. In both interventions, participants received a treatment manual, performed weekly PP (e.g. gratitude letter) or CF (e.g. recalling daily events) exercises, and completed weekly one-on-one telephone sessions over 6 weeks. Between-group differences in hopelessness (primary outcome), depression, suicidality and positive psychological constructs at 6 and 12 weeks were tested using mixed-effects models accounting for intensity of post-hospitalization psychiatric treatment. RESULTS: Compared with PP, the CF intervention was associated with significantly greater improvements in hopelessness at 6 weeks (ß = -3.15, 95% confidence interval -6.18 to -0.12, effect size = -0.84, p = 0.04), but not 12 weeks. Similarly, the CF intervention led to greater improvements in depression, suicidal ideation, optimism and gratitude at 6 and 12 weeks. CONCLUSIONS: Contrary to our hypothesis, the CF intervention was superior to PP in improving hopelessness, other suicide risk factors and positive psychological constructs during a key post-discharge period among suicidal patients with depression. Further study of this CF intervention is warranted in populations at high suicide risk.

RESUMO

Positive psychological constructs are associated with superior outcomes in cardiac patients, but there has been minimal study of positive psychology (PP) interventions in this population. Our objective was to describe the intervention development and pilot testing of an 8-week phone-based PP intervention for patients following an acute coronary syndrome (ACS). Initial intervention development and single-arm proof-of-concept trial, plus comparison of the PP intervention to a subsequently-recruited treatment as usual (TAU) cohort. PP development utilized existing literature, expert input, and qualitative interview data in ACS patients. In the proof-of-concept trial, the primary outcomes were feasibility and acceptability, measured by rates of exercise completion and participant ratings of exercise ease/utility. Secondary outcomes were pre-post changes in psychological outcomes and TAU comparisons, measured using effect sizes (Cohen's d). The PP intervention and treatment manual were successfully created. In the proof-of-concept trial, 17/23 PP participants (74 %) completed at least 5 of 8 exercises. Participants rated the ease (M = 7.4/10; SD = 2.1) and utility (M = 8.1/10, SD = 1.6) of PP exercises highly. There were moderate pre-post improvements (ds = .46-.69) in positive affect, anxiety, and depression, but minimal effects on dispositional optimism (d = .08). Compared to TAU participants (n = 22), PP participants demonstrated greater improvements in positive affect, anxiety, and depression (ds = . 47-.71), but not optimism. A PP intervention was feasible, well-accepted, and associated with improvements in most psychological measures among cardiac patients. These results provide support for a larger trial focusing on behavioral outcomes.

RESUMO

BACKGROUND: Depression and anxiety are common in patients with coronary artery disease (CAD). Although depression clearly has been associated with mortality in this population, the relationship between anxiety and mortality is less clear. Accordingly, we performed a series of meta-analyses to (1) examine the relationship between anxiety and mortality in patients with established CAD and (2) determine if this relationship differs in patients with stable CAD compared to those who have just had an acute coronary syndrome (ACS). METHODS AND RESULTS: Systematic literature searches identified 44 articles (total N = 30,527) evaluating the prospective relationship between anxiety and mortality in individuals with established CAD. A series of 8 adjusted and unadjusted meta-analyses were performed to examine this relationship across all patients, with sensitivity analyses completed in post-ACS and stable CAD cohorts. In unadjusted analyses, anxiety was associated with a moderate increase in mortality risk (odds ratio 1.21 per SD increase in anxiety). However, when adjusting for covariates, nearly all associations became nonsignificant. In sensitivity analyses, anxiety was associated with an increased risk of poor outcomes in the stable CAD-but not post-ACS-cohort. CONCLUSIONS: These analyses confirm that anxiety is associated with increased risk of mortality in patients with CAD; however, this relationship is not as strong as that of depression and may be explained partly by other clinical factors. If anxiety screening is performed, it should be performed during a period of clinical stability and should target anxiety disorders rather than anxiety symptoms alone.

RESUMO

Adherence to antiretroviral therapy (ART) among HIV-infected individuals is necessary to both individual and public health, and psychosocial problems have independently been associated with poor adherence. To date, studies have not systematically examined the effect of multiple, co-occurring psychosocial problems (i.e., "syndemics") on ART adherence. Participants included 333 HIV-infected individuals who completed a comprehensive baseline evaluation, as part of a clinical trial to evaluate an intervention to treat depression and optimize medication adherence. Participants completed self-report questionnaires, and trained clinicians completed semi-structured diagnostic interviews. ART non-adherence was objectively measured via an electronic pill cap (i.e., MEMS). As individuals reported a greater number of syndemic indicators, their odds of non-adherence increased. Co-occurring psychosocial problems have an additive effect on the risk for poor ART adherence. Future behavioral medicine interventions are needed that address these problems comprehensively, and/or the core mechanisms that they share.

RESUMO

Evidence suggests that smoking may have negative associations with HIV health outcomes. The smoking rate in our sample of people living with HIV (N = 333) was triple that of the general population (57 v. 19 %). Regression analyses revealed that (smokers v. non-smokers) reported lower medication adherence (unstandardized beta = 9.01) and were more likely to have a detectable viral load (OR = 2.85, 95 % CI [1.53-5.30]). Smokers attended fewer routine medical visits (ß = -0.16) and were more likely to report recent hospitalization (OR = 1.89, 95 % CI [0.99, 3.57]). Smokers ranked "health" as less important to their quality of life (ß = -0.13) and were more likely to report problematic alcohol (OR = 2.40, 95 % CI [1.35, 4.30]), cocaine (OR = 2.87, 95 % CI [1.48-5.58]), heroin (OR = 4.75, 95 % CI [1.01, 22.30]), or marijuana use (OR = 3.08, 95 % CI [1.76-5.38]). Findings underscore the need for integrated behavioral smoking cessation interventions and routine tobacco screenings in HIV primary care.

RESUMO

OBJECTIVES: Approximately 32.7% of people living with HIV/AIDS (PLWHA) in the USA are now over the age of 50. Women comprise a significant percentage of the US HIV epidemic and the percentage of women diagnosed with HIV continues to grow; however, little is known about women's experiences living and coping with HIV over time. The goal of this study was to explore the experiences of US women over 50 living with HIV to better understand how they make sense of their diagnosis and cope with their illness over time and during the aging process. METHOD: Nineteen women (mean age = 56.79, SD = 4.63) referred from Boston-area organizations and hospitals completed one-time, in-depth individual interviews, out of which 47% of the participants were identified as Black/African Americans, and 37% as White. The average time since diagnosis was 16.32 years (SD = 5.70). Inclusion criteria included: (1) female sex, (2) aged 50 or older, (3) HIV diagnosis, and (4) English speaking. Transcribed interviews were analyzed using a grounded theory approach and NVivo 9 software. RESULTS: Findings are described across the following themes: (1) experiences at diagnosis, (2) uncertainty of disease course, (3) acceptance, and (4) living 'well' with HIV. Participants appeared to be well adjusted to their HIV diagnosis and described a progression to acceptance and survivorship; they identified strategies to 'live well' in the context of HIV. For some, health-related uncertainty about the future remained. These findings were organized into a model of coping with HIV. CONCLUSION: Themes and issues identified by this study may help guide interventions across the lifespan for women with HIV.

RESUMO

There are an estimated 1.1 million individuals living with HIV/AIDS in the United States. In addition to the various medical comorbidities of HIV infection, depression is one of the most frequently co-occurring psychiatric conditions among HIV-infected individuals. Furthermore, depression has been found to be associated with nonadherence to antiretroviral therapy (ART), as well as HIV disease progression. Cognitive behavioral therapy (CBT) has repeatedly been found to effectively treat depression in adult populations, and CBT for adherence and depression (CBT-AD) is an effective treatment for improving depressive symptoms and medication adherence in the context of various chronic health conditions, including diabetes and HIV-infection. This paper provides a description of the CBT-AD approach to treat depression and ART adherence in HIV-infected adults, which we have developed and tested in our clinic, and for which detailed therapist and client guides exist. To augment the description of treatment, the present article provides video component demonstrations of several core modules that highlight important aspects of this treatment, including Life-Steps for medication adherence, orientation to CBT-AD and psychoeducation, and suggestions for adaptation of core CBT modules for HIV-infected adults. Discussion of video demonstrations highlights differences in patient presentations and course of treatment between HIV-infected adults receiving CBT-AD and HIV-uninfected adults receiving traditional CBT for depression. This description and the accompanying demonstrations are intended as a practical guide to assist therapists wishing to conduct such a treatment in the outpatient setting.

RESUMO

Maize was first domesticated in a restricted valley in south-central Mexico. It was diffused throughout the Americas over thousands of years, and following the discovery of the New World by Columbus, was introduced into Europe. Trade and colonization introduced it further into all parts of the world to which it could adapt. Repeated introductions, local selection and adaptation, a highly diverse gene pool and outcrossing nature, and global trade in maize led to difficulty understanding exactly where the diversity of many of the local maize landraces originated. This is particularly true in Africa and Asia, where historical accounts are scarce or contradictory. Knowledge of post-domestication movements of maize around the world would assist in germplasm conservation and plant breeding efforts. To this end, we used SSR markers to genotype multiple individuals from hundreds of representative landraces from around the world. Applying a multidisciplinary approach combining genetic, linguistic, and historical data, we reconstructed possible patterns of maize diffusion throughout the world from American "contribution" centers, which we propose reflect the origins of maize worldwide. These results shed new light on introductions of maize into Africa and Asia. By providing a first globally comprehensive genetic characterization of landraces using markers appropriate to this evolutionary time frame, we explore the post-domestication evolutionary history of maize and highlight original diversity sources that may be tapped for plant improvement in different regions of the world.

RESUMO

Many HIV-infected injection drug users (IDUs) continue to use illicit substances despite being in substance use treatment. Substance use is associated with non-adherence to HIV medications; however underlying mechanisms regarding this relation are understudied. The current investigation examined the role of substance use coping in terms of the relation between substance use and HIV medication adherence. Participants were 121 HIV-infected IDUs (41 % female, M age = 47, SD = 7.1) in opioid dependence treatment. Participants completed self-report questionnaires, were administered clinical interviews and oral toxicology screens, and used a medication-event-monitoring-system cap to assess 2 week HIV medication adherence. The use of cocaine and multiple substances were significantly related to decreased medication adherence. Substance use coping mediated these associations. Findings highlight the importance of assessing, monitoring, and targeting ongoing substance use, and ways to increase positive coping for HIV-infected IDUs in substance use treatment to aid in HIV medication adherence.

RESUMO

We conducted a preliminary RCT among 40 HIV-positive Latinos of Mexican descent on the U.S.-Mexico border who indicated imperfect adherence and depressive symptomatology. Participants were randomly assigned to culturally adapted cognitive-behavioral therapy for adherence and depression with an alarmed pillbox or usual care. Outcomes were depressive symptoms (self-report and blind clinician ratings), adherence (self-report and electronic pillbox), and biological markers. The intervention, delivered in English and Spanish, proved feasible and acceptable. Generalized estimating equations in intent-to-treat analyses showed some effects of "moderate" to "large" size, with maintenance over time. For example, intervention (vs. control) participants demonstrated at post-intervention a greater drop in BDI scores (OR = -3.64, p = 0.05) and greater adherence according to the electronic pillbox (OR = 3.78, p = 0.03). Biological markers indicated some relative improvement for CD4 count but not VL. The promising results suggest a larger trial to determine efficacy is warranted.

RESUMO

Background COVID-19 and efforts to manage widespread infection may compromise HIV care engagement. The COVID-19-related factors linked to reduced HIV engagement have not been assessed among postpartum women with HIV, who are at heightened risk of attrition under non-pandemic circumstances. To mitigate the effects of the pandemic on care engagement and to prepare for future public health crises, it is critical to understand how COVID-19 has impacted (1) engagement in care and (2) factors that may act as barriers to care engagement. Methods A quantitative assessment of COVID-19-related experiences was added to a longitudinal cohort study assessing predictors of postpartum attrition from HIV care among women in South Africa. Participants (N = 266) completed the assessment at 6, 12, 18, or 24 months postpartum between June and November of 2020. Those who endorsed one or more challenge related to engagement in care (making or keeping HIV care appointments, procuring HIV medications, procuring contraception, and/or accessing immunization services for infants; n = 55) were invited to complete a brief qualitative interview, which explored the specific factors driving these challenges, as well as other impacts of COVID-19 on care engagement. Within this subset, 53 participants completed an interview; qualitative data were analyzed via rapid analysis. Results Participants described key challenges that reduced their engagement in HIV care and identified four other domains of COVID-19-related impacts: physical health, mental health, relationship with a partner or with the father of the baby, and motherhood/caring for the new baby. Within these domains, specific themes and subthemes emerged, with some positive impacts of COVID-19 also reported (e.g., increased quality time, improved communication with partner, HIV disclosure). Coping strategies for COVID-19-related challenges (e.g., acceptance, spirituality, distraction) were also discussed. Conclusions About one in five participants reported challenges accessing HIV care, medications, or services, and they faced complex, multilayered barriers to remaining engaged. Physical health, mental health, relationships with partners, and ability to care for their infant were also affected. Given the dynamic nature of the pandemic and general uncertainty about its course, ongoing assessment of pandemic-related challenges among postpartum women is needed to avoid HIV care disruptions and to support wellbeing.

RESUMO

In the US, Latino MSM are disproportionately affected by HIV, yet there is a paucity of data for this risk group. To this end, we examined data on Latino and non-Latino white MSM who participated across six cities in a 2-year randomized behavioral intervention study-Project EXPLORE. At baseline, Latinos reported significantly more serodiscordant unprotected anal intercourse (SDUA) than non-Latinos. Longitudinal predictors of SDUA included marijuana, poppers, amphetamines and heavy drinking, as well as lower self-efficacy, poorer communication skills, weaker safe-sex norms and more enjoyment of risky sex. For HIV infection, Latinos had significantly higher seroconversion rate over follow-up than non-Latinos. Longitudinal predictors of seroconversion among Latinos included poppers and SDUA. Intervention effects did not significantly differ between Latino and non-Latinos. Findings support HIV intervention work with Latino MSM that includes skills training/counseling to address attitudes about safe sex and impact of substance use on HIV-risk behavior and acquisition.

RESUMO

OBJECTIVE: MSM in India are at a high risk for HIV infection given psychosocial challenges, sexual orientation stress, and stigma. We examined the cost-effectiveness of a novel resilience-based psychosocial intervention for MSM in India. DESIGN: We parameterized a validated microsimulation model (CEPAC) with India-specific data and results from a randomized trial and examined two strategies for MSM: status quo HIV care ( SQ ), and a trial-based psychosocial intervention ( INT ) focused on building resilience to stress, improving mental health, and reducing condomless anal sex (CAS). METHODS: We projected lifetime clinical and economic outcomes for MSM without HIV initially. Intervention effectiveness, defined as reduction in self-reported CAS, was estimated at 38%; cost was $49.37/participant. We used a willingness-to-pay threshold of US$2100 (2019 Indian per capita GDP) per year of life saved (YLS) to define cost-effectiveness. We also assessed the 5-year budget impact of offering this intervention to 20% of Indian MSM. RESULTS: Model projections showed the intervention would avert 2940 HIV infections among MSM over 10 years. Over a lifetime horizon, the intervention was cost-effective (ICER = $900/YLS). Results were most sensitive to intervention effectiveness and cost; the intervention remained cost-effective under plausible ranges of these parameters. Offering this intervention in the public sector would require an additional US$28 M over 5 years compared with SQ . CONCLUSION: A resilience-based psychosocial intervention integrated with HIV risk reduction counseling among MSM in India would reduce HIV infections and be cost-effective. Programs using this approach should be expanded as a part of comprehensive HIV prevention in India.

RESUMO

BACKGROUND: Ethnic minorities with depression are more likely to seek mental health care through primary care providers (PCPs) than mental health specialists. However, both provider and patient-specific challenges exist. PCP-specific challenges include unfamiliarity with depressive symptom profiles in diverse patient populations, limited time to address mental health, and limited referral options for mental health care. Patient-specific challenges include stigma around mental health issues and reluctance to seek mental health treatment. To address these issues, we implemented a multi-component intervention for Asian American and Latino American primary care patients with depression at Massachusetts General Hospital (MGH). METHODS/DESIGN: We propose a randomized controlled trial to evaluate a culturally appropriate intervention to improve the diagnosis and treatment of depression in our target population. Our goals are to facilitate a) primary care providers' ability to provide appropriate, culturally informed care of depression, and b) patients' knowledge of and resources for receiving treatment for depression. Our two-year long intervention targets Asian American and Latino American adult (18 years of age or older) primary care patients at MGH screening positive for symptoms of depression. All eligible patients in the intervention arm of the study who screen positive will be offered a culturally focused psychiatric (CFP) consultation. Patients will meet with a study clinician and receive toolkits that include psychoeducational booklets, worksheets and community resources. Within two weeks of the initial consultation, patients will attend a follow-up visit with the CFP clinicians. Primary outcomes will determine the feasibility and cost associated with implementation of the service, and evaluate patient and provider satisfaction with the CFP service. Exploratory aims will describe the study population at screening, recruitment, and enrollment and identify which variables influenced patient participation in the program. DISCUSSION: The study involves an innovative yet practical intervention that builds on existing resources and strives to improve quality of care for depression for minorities. Additionally, it complements the current movement in psychiatry to enhance the treatment of depression in primary care settings. If found beneficial, the intervention will serve as a model for care of Asian American and Latino American patients.
