Substance abuse, violence, HIV, and depression: an underlying syndemic factor among Latinas.

Background:Evidence from the literature suggests that substance abuse, violence, HIV risk, depressive symptoms, and underlying socioeconomic conditions are tied intrinsically to health disparities among Latinas. Although these health and social conditions appear to comprise a syndemic, an underlying phenomenon disproportionately accounting for the burden of disease among marginalized groups, these hypothesized relationships have not been formally tested. Objectives:The aim of this study was to assess (a) if substance abuse, violence, HIV risk, and depressive symptoms comprised a syndemic and (b) if this syndemic was related to socioeconomic disadvantage among Latinas. Methods:Baseline assessment data from a randomized controlled community trial testing the efficacy of an HIV risk reduction program for adult Latinas (n = 548) were used to measure demographic variables, substance abuse, violence, risk for HIV, and depressive symptoms. Structural equation modeling was used to test a single underlying syndemic factor model and any relation to socioeconomic disadvantage. Results:The results of this study support the idea that HIV risk, substance abuse, violence, and depressive symptoms comprise a syndemic, &khgr;2(27) = 53.26, p < .01 (relative &khgr;2 = 1.97, comparative fit index = .91, root mean square error of approximation = .04). In addition, in limited accord with theory, this factor was related to 2 measures of socioeconomic disadvantage, percentage of years in the United States (b = 7.55, SE = 1.53, p < .001) and education (b = −1.98, SE = .87, p < .05). Discussion:The results of this study could be used to guide public health programs and policies targeting behavioral health disparity conditions among Latinos and other vulnerable populations. Further study of the influence of gender-role expectations and community-level socioeconomic indicators may provide additional insight into this syndemic.

A Randomized Controlled Trial of Structural Ecosystems Therapy for HIV Medication Adherence and Substance Abuse Relapse Prevention

BACKGROUND Substance abuse in women with HIV/AIDS overshadows other priorities, including health care. Substance abuse may cause women to avoid health care systems and not adhere to their medication regimen. METHODS A randomized controlled trial tested the efficacy of Structural Ecosystems Therapy (SET) relative to a psychoeducational Health Group (HG) in 126 HIV+ women in recovery. SET, a 4-month intervention, focused on building family support for relapse prevention and HIV medication adherence. Over 12-month follow-up, women were assessed for drug use and medication adherence every 2 months; CD4 T-cell count and HIV viral load were assessed every 4 months. RESULTS Levels of drug use did not differ by condition. There was a significant difference in curvature of the rates of change in drug use with SET increasing and then decreasing and HG decreasing and then increasing. Women in SET were more likely to increase substance abuse services in response to relapse and separate from drug using household members than were women in HG. These two changes explained the decline in drug use observed within SET between 6 and 12 months. SET showed declines in medication adherence but increases in CD4 T-cell count relative to HG. The increase in CD4 T-cell count in SET was related to increasing proportions of women in SET taking antiretroviral medications. CONCLUSION The results of the trial were mixed. Women in SET did not show better drug use or medication adherence outcomes, but did show improvement in CD4 T-cell count and theoretical mechanisms of action on drug relapse.

Aging, gender, and self: Dimensionality and measurement invariance analysis on self-construal

The dimensionality of self-construal, and the consistency of this dimensionality across age and gender, was examined using confirmatory factor and measurement invariance analyses. Across young and older adults, across men and women, and across White Americans and Hispanic Americans, a four-factor solution, including vertical and horizontal interdependence and vertical and horizontal independence, fitted the data better than a two-factor solution with vertical and horizontal dimensions posited as single factors. These results support the hypothesized individual-level multidimensionality of self-construal and suggest that it is structurally similar to the dimensionality of individualism – collectivism at the cultural level. Latent mean comparisons revealed that elders valued uniqueness, on average, more than young adults and that both genders strive equally for achievement, albeit through different means. Implications for cross-level (i.e., cultural vs. individual) and multidimensional understandings of the self are discussed.

Birthplace, Culture, Self-Esteem, and Intimate Partner Violence Among Community-Dwelling Hispanic Women:

The purpose of this study was to explore variations in demographics, culture, self-esteem, and intimate partner violence among Hispanic women according to birthplace, and to identify factors associated with these differences in intimate partner violence (IPV). Baseline data from a randomized control trial testing the efficacy of an HIV prevention program were used. Path analyses identified differences in IPV between Colombian women and women from other Central/South American countries. Self-esteem was the only factor associated with these differences. Interventions addressing the unique needs of Hispanic women from different subgroups are needed.

Engagement, Retention, and Abstinence for Three Types of Opioid Users in Florida

Prescription opioid use has grown rapidly, but few studies examined whether users have similar treatment responses as heroin users. Participants were 1,648 opioid users in Florida Access to Recovery (2004–2007). Participants engaged in methadone or buprenorphine maintenance had better retention than those in nonmaintenance treatment. Heroin only users (HO) had better engagement in nonmaintenance treatments and had worse retention than prescription opioid only users (PO). In methadone maintenance, PO were more likely to report opioid abstinence during treatment than heroin and prescription opioid users (H&P). Future research should focus on understanding and improving the treatment experience of opioid use subgroups.

Family mechanisms of structural ecosystems therapy for HIV-seropositive women in drug recovery

OBJECTIVE Examined the effects of Structural Ecosystems Therapy (SET), a family intervention for women living with HIV or AIDS, compared to a psycho-educational health group (HG) intervention, and reciprocal relationships between women and family members. METHOD Women (n = 126) and their family members (n = 269) were randomized to one of two conditions and assessed every 4 months for 12 months. Family functioning, drug use, and psychological distress was reported by multiple family members. RESULTS Multilevel growth curve modeling showed a different family functioning trajectory between SET and HG, B = -0.05, SE = 0.02, p < .01. There was no intervention effect on the trajectory of family-level drug abstinence or psychological distress, but there was a significant difference in the trajectory of psychological distress after controlling for change in family functioning, B = -0.28, SE = 0.13, p < .05. There was an indirect effect from treatment through change in family functioning to change in psychological distress, B = 0.29, SE = 0.12, p < .05. With respect to reciprocal effects, family drug abstinence significantly predicted womens abstinence 4 months later, B = 0.22, SE = 0.06, p < .001. CONCLUSION Findings demonstrated the interdependence of family members and the impact of family in relapse prevention and partially supported SETs potential for maintaining family functioning and well-being for women living with HIV or AIDS in drug recovery.

Mechanisms of Partner Violence Reduction in a Group HIV-Risk Intervention for Hispanic Women

The objective of this study was to test whether partner communication about HIV and/or alcohol intoxication mediated reductions in intimate partner violence (IPV) in SEPA (Salud [health], Educación [education], Promoción [promotion], y [and] Autocuidado [self-care]), a culturally specific, theoretically based group HIV-risk reduction intervention for Hispanic women. SEPA had five sessions covering sexually transmitted infection (STI)/HIV prevention, partner communication, condom negotiation and use, and IPV. SEPA reduced IPV and alcohol intoxication, and improved partner communication compared with controls in a randomized trial with adult U.S. Hispanic women (SEPA, n = 274; delayed intervention control, n = 274) who completed structured interviews at baseline and 3, 6, and 12 months post-baseline. Parallel process latent growth curve models indicated that partner communication about HIV mediated the reduction in male-to-female IPV in SEPA, B = −0.78, SE = 0.14, p< .001, but alcohol intoxication did not, B = −0.15, SE = 0.19, p = .431. Male-to-female IPV mediated the intervention effect on female-to-male IPV, B = −1.21, SE = 0.24, p< .001. Skills building strategies originally designed to enhance women’s communication with their partners about sexual risk behaviors also worked to reduce male-to-female IPV, which in turn reduced female-to-male IPV. These strategies could be integrated into other types of health promotion interventions.

The efficacy of two adolescent substance abuse treatments and the impact of comorbid depression: results of a small randomized controlled trial.

OBJECTIVE The purpose of this randomized trial was to investigate the efficacy of 2 behavioral treatments focusing on different change mechanisms in ameliorating a borderline personality disorder constellation of behaviors and substance use in adolescents referred by juvenile diversion programs. METHODS Forty adolescents 14-17 years of age and meeting Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria for borderline personality disorder and substance use disorders were randomized to integrative borderline personality disorder-oriented adolescent family therapy (I-BAFT) or individual drug counseling. This design allowed a comparison of 2 manualized interventions, 1 family based and 1 individually oriented. Profiles of clinical change were used to detect impact and estimate treatment effect sizes. RESULTS Primary analyses showed that both interventions had a clinically significant impact on borderline personality disorder behaviors 12 months after baseline but with no differential treatment effects. The impact on substance use was more complex. Subgroup analyses revealed that adolescents with depression had significantly more severe profiles of borderline personality disorder and substance use. These youths were the only group to show reductions in substance use, but they only did so if they received the I-BAFT intervention. Study data also documented the high dosage of intensive residential treatment needed by this population. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE Results highlight the intensive treatment needs of juvenile justice-involved youths with co-occurring substance use and borderline personality disorder including depression, the hybrid outpatient and residential treatment often required by this population, and the promise of a family-oriented approach, particularly for youths with severe symptoms and co-occurring depression.

Predictors of Depressive Symptoms Among Hispanic Women in South Florida

U.S. Hispanics, especially women, experience a disproportionate amount of disease burden for depression. This disparity among Hispanic women necessitates examination of factors associated with depression. The objective of this study was to use an adaptation of the Stress Process Model to test whether self-esteem mediated the relationship between Hispanic stress and depressive symptoms. Data for this secondary analysis were from a previous randomized-control HIV prevention trial.  Participants were 548 Hispanic women (19-52 years). Data collection measures included the Center for Epidemiological Studies–Depression Scale, Rosenberg Self-Esteem Scale, and Hispanic Stress Scale. The bootstrap method in Mplus 6 was used to test mediation. Results indicated that self-esteem was inversely related to depression, and Hispanic stress was found to be positively related to depression. Self-esteem partially mediated the relationship between stress and depression. Strategies to improve/maintain self-esteem should be considered in future interventions for Hispanic women with depression.

Participation in SEPA, a Sexual and Relational Health Intervention for Hispanic Women

HIV and intimate partner violence (IPV) risks are linked in Hispanic women, so integrated interventions can efficiently produce meaningful change. Integrated interventions for Hispanic women are promising, but factors that put Hispanic women at risk for HIV and violence may also impede engagement with interventions. This study examined barriers and facilitators of engagement in a group educational intervention, SEPA (Salud, Educación, Prevención y Autocuidado [Health, Education, Prevention, and Self-Care]), for Hispanic women. A total of 274 Hispanic women from South Florida in the SEPA condition of a randomized controlled trial completed baseline measures of violence, depression, familism, Hispanic stress, acculturation, and demographics, and 57% of the women engaged (attended two of five sessions). Education, IPV, and acculturation predicted engagement. Understanding engagement advances intervention development/refinement. Hispanic women who experience relationship violence are open to group interventions. Further program development and outreach work are needed to connect women with low education, who are particularly vulnerable.
