Brief screening for co-occurring disorders among women entering substance abuse treatment.

BACKGROUND: Despite the importance of identifying co-occurring psychiatric disorders in substance abuse treatment programs, there are few appropriate and validated instruments available to substance abuse treatment staff to conduct brief screen for these conditions. This paper describes the development, implementation and validation of a brief screening instrument for mental health diagnoses and trauma among a diverse sample of Black, Hispanic and White women in substance abuse treatment. With input from clinicians and consumers, we adapted longer existing validated instruments into a 14 question screen covering demographics, mental health symptoms and physical and sexual violence exposure. All women entering treatment (methadone, residential and out-patient) at five treatment sites were screened at intake (N = 374). RESULTS: Eighty nine percent reported a history of interpersonal violence, and 70% reported a history of sexual assault. Eighty-eight percent reported mental health symptoms in the last 30 days. The screening questions administered to 88 female clients were validated against in-depth psychiatric diagnostic assessments by trained mental health clinicians. We estimated measures of predictive validity, including sensitivity, specificity and predictive values positive and negative. Screening items were examined multiple ways to assess utility. The screen is a useful and valid proxy for PTSD but not for other mental illness. CONCLUSION: Substance abuse treatment programs should incorporate violence exposure questions into clinical use as a matter of policy. More work is needed to develop brief screening tools measures for front-line treatment staff to accurately assess other mental health needs of women entering substance abuse treatment.

A comparison of maternal interview and medical record ascertainment of violence among women who had poor pregnancy outcomes.

OBJECTIVES: This study investigated the agreement between self-reported and medical record assessment of exposure to violence and the impact of misclassification on the estimation of the association between exposure to violence and infant death and very low birthweight. METHODS: The study population consisted of women who participated in two case-control studies on infant death and very low birthweight. There were 254 pairs of interviews and medical record reviews available for comparison. RESULTS: A total of 153 women (60.2%) reported ever being exposed to violence--92 (60.1%) based on the interview only, 18 (11.8%) based on the medical record only, and 43 (28.1%) in both sources. The sensitivity of the violence variables was low, ranging from 16.9% to 31.9% and kappa statistics showed poor agreement. Lower rates of all types of violence were found through the medical record than through the interview. CONCLUSION: Prevalence of violence based on medical record alone had a high degree of misclassification and some odds ratios were biased toward the null. Studies in which violence is an exposure, outcome, or confounder must use participant interviews in order to gather accurate information. A combination of sources may be the most accurate.

Improving drug treatment services for Hispanics: research gaps and scientific opportunities.

Delivery of services to Hispanic drug users remains a great challenge, as shown by low service access and retention, and disproportionate negative consequences of drug abuse in the Hispanic population. This paper provides a critical analysis of current services research on Hispanics with drug abuse problems, identifies gaps in the knowledge, and offers recommendations for scientific opportunities to address these gaps, focusing on four central needs: (1) the need to understand the circumstances of Hispanics in their own communities (i.e., community context); (2) the need to develop and test service delivery models tailored to Hispanics' circumstances and special needs; (3) the need to remove client, provider, and system barriers to utilization; and (4) the need to establish links between drug abuse services, social services, and other service sectors to optimize treatment outcomes. The authors suggest an approach that begins with a focus on the local Hispanic community and builds understanding of the cultural context, inclusion of indigenous resources, recognition of barriers to enrollment and retention, and coordination of related services.

The prevention of HIV transmission in Hispanic adolescents.

This article reviews the state of the science in HIV prevention for Hispanic adolescents. The article discusses the importance of preventing HIV in Hispanic adolescents. Literature is reviewed in three broad areas: (1) the prevalence rates of drug and alcohol misuse, sexual practices, and HIV infection; (2) risk and protective factors for drug and alcohol misuse and unprotected sex (in general and specifically for Hispanics); and (3) the state of HIV prevention intervention development and evaluation targeting Hispanic youth. Seven specific recommendations are advanced in areas that have the potential to further the field of HIV prevention for Hispanic adolescents.

Perpetration of intimate partner violence associated with sexual risk behaviors among young adult men.

OBJECTIVE: We assessed the association between intimate partner violence (IPV) perpetration and sexual risk behaviors and fatherhood (having fathered children) among young men. METHODS: Sexually active men aged 18 to 35 years who visited an urban community health center and who reported having sexual intercourse with a steady female partner during the past 3 months (N = 283) completed a brief self-administered survey about sexual risk behaviors, IPV perpetration, and demographics. We conducted logistic regression analyses adjusted for demographics to assess associations between IPV and sexual risk behaviors and fatherhood. RESULTS: Participants were predominantly Hispanic (74.9%) and Black (21.9%). Participants who reported IPV perpetration during the past year (41.3%) were significantly more likely to report (1) inconsistent or no condom use during vaginal and anal sexual intercourse, (2) forcing sexual intercourse without a condom, (3) having sexual intercourse with other women, and (4) having fathered 3 or more children. CONCLUSION: IPV perpetration was common among our sample and was associated with increased sexual risk behaviors. Urban community health centers may offer an important venue for reaching this at-risk population.

Needs and scientific opportunities for research on substance abuse treatment among Hispanic adults.

The results of a focused search of the literature on empirical studies of substance abuse treatment outcomes with Hispanic adults are reviewed. Also provided are key research opportunities and recommendations on substance abuse treatment for Hispanics. The paper is divided into two major sections: the first focuses on behavioral drug treatment studies on Hispanic adults, and the second identifies published original articles in pharmacotherapy, namely that more empirical research is needed to determine which treatments are efficacious with Hispanic populations. For treatment modalities not associated with promising effect sizes with Hispanic samples, cultural modifications may be needed to improve the compatibility of the treatment with Hispanic culture. For those treatments found to have promising effect sizes with various Hispanic subgroups, with Hispanics at different levels of acculturation, and with Hispanics from various socioeconomic backgrounds. The authors stress the need for theory-driven interventions to be developed specifically for well-characterized Hispanic subgroups (e.g., suburban middle-income Puerto Ricans living in the Northeast).

Comparison of sexual and drug use behaviors between female sex workers in Tijuana and Ciudad Juarez, Mexico.

Female sex workers (FSWs) have been documented to have high rates of sexually transmitted diseases and HIV in many parts of the world. However, little work has been done to characterize the prevalence of these infections along the U.S.-Mexican border, where sexual tourism and culturally sanctioned sex work among nationals is widespread. The objective of this study was to compare differences in background characteristics, HIV risk behaviors, drug use, and sexually transmitted infection/HIV prevalence between FSWs who participated in a behavioral risk intervention in two U.S.-Mexican border cities. Baseline data were collected from March 2004 through September 2005. Data from 295 FSWs were compared between Tijuana and Ciudad (Cd.) Juarez. Among 155 FSWs in Tijuana and 140 in Cd. Juarez, HIV seroprevalence was 4.8% and 4.9%, respectively. FSWs in Cd. Juarez were more likely to test positive for active syphilis (31.3%) compared with Tijuana (11.8%) but did not differ in terms of the prevalence of gonorrhea and chlamydia. FSWs in both sites reported high levels of unprotected sex and use of drugs; however, FSWs in Cd. Juarez were more likely than those in Tijuana to ever have injected drugs (75% vs. 25%, p <.001). Heroin and cocaine use and injection drug use were significantly more common in Cd. Juarez, whereas methamphetamine use was more common in Tijuana. Injection of vitamins was common in both cities. Logistic regression analyses suggested that being younger, working in Cd. Juarez, and using heroin or cocaine were independently associated with active syphilis infection. In Tijuana, methamphetamine use was strongly associated with active syphilis infection. These preliminary results suggest that risk profiles for HIV/sexually transmitted infection among FSWs in these two Mexico-U.S. border cities differ, suggesting a need to tailor interventions to the specific needs in each city.

Substance abuse treatment in the Commonwealth of Massachusetts: gaps, consequences and solutions.

This issue brief outlines five strategies for improving the quality of treatment in Massachusetts: (1) Engaging detoxification clients in a broader continuum of treatment, (2) Improving retention in treatment, (3) Providing client/family-centered services, (4) Increasing the use of evidence-based treatment approaches, and (5) Supporting recovery to address the chronic nature of substance use disorders. These strategies are essential to maximizing the impact of our substance abuse dollars. We need to do it right and then expand access to treatment more broadly and fill the treatment gap. Although not the focus of this report we need to think harder about upfront prevention and efforts to encourage more people to seek care. Part of the public strategy also requires better coordination between BSAS, MassHealth, provider organizations, and other state agencies, including criminal justice and mental health agencies. Through these efforts we can reduce the costs and consequences of substance abuse and build a healthier, more productive community.

HIV prevention community planning: challenges and opportunities for data-informed decision-making.

The use of data in decision-making by the Massachusetts Prevention Planning Group (MPPG) was assessed using multiple methods: in-depth interviews, member surveys, directed observations, and archival review. Three factors known to influence group decision-making were of interest: (1) member characteristics, (2) group structure, and (3) data inputs. Membership characteristics were not related to reliance on data. However, group structure factors and data inputs were directly related to reliance on data. Most members accepted an advisory role and felt participation was worthwhile. About half were dissatisfied with decision-making processes, citing member conflicts and distrust. Incompleteness of data, inadequate presentation quality, and lengthy intervals between presentations and actual decision-making were identified as deficits. Although most members reported skills with HIV- and intervention-related data, most also reported deficiencies in interpreting evaluation and cost-effectiveness studies. Member trust and use of data in decision-making could be improved by clarifying decision-making structures and processes, assuring high-quality data presentations, and supporting or training members to better interpret and use data.

Bridging data and decision making: development of techniques for improving the HIV prevention community planning process.

Assessments of community planning in Massachusetts and Texas were used to develop tools for increasing the use of data by HIV prevention community planning groups (CPGs) and prevention providers while also increasing participation of CPG members. Barriers to data use included organizational problems in CPGs (e.g., lack of clear procedures, distrust of peers and leadership) and technical assistance needs for CPG members and researchers who provide data. The absence of data relevant to local epidemics was another barrier. Specific linkages are provided between the assessments of these needs and the development of a technical assistance tools (e.g., websites, templates for data presentation, experiential involvement in data use) and strategies for organizational change in CPGs, as well as efforts to better use available data and create or identify new sources of local data.

HIV prevention community planning: enhancing data-informed decision-making.

The primary purpose of this study was to test the impact of the first year of a 3-year intervention designed to enhance the use of behavioral data in the Massachusetts HIV Prevention Community Planning Group (MPPG). A one-group, pretest-posttest, nonequivalent independent variables, quasi-experimental design was used to assess changes before and after the first year of implementing strategies to enhance the use of behavioral data in decision-making. Over 90% of the CPG members completed surveys at baseline and at the end of the first year of the intervention. Consistent with the focus of the MPPG intervention in Year One, significant improvements were found from baseline to follow-up in member perceptions of decision-making structure and leadership, satisfaction with prevention planning processes, and intervention prioritization decisions. Findings provide preliminary evidence for the impact on member satisfaction of changes in CPG organizational structures and processes, including redistribution of power and broader constituent representation.

Improving the use of data for HIV prevention decision making: lessons learned.

HIV prevention community planning was developed to promote identification of local prevention priorities through a process that was evidence-based and provided community input. There are a variety of barriers to effective use of data in community planning which include characteristics of data (availability, timeliness, relevance to planning tasks), characteristics of planning group members and providers of data (e.g., skills in understanding and applying data), and social-organizational aspects of community-planning groups (CPGs). Lessons learned from this project illustrate how to create locally relevant sources of data, build data use skills of CPG members and data providers, and address social-organizational aspects of planning, while also better integrating community planning with implementation of prevention plans. Adaptation of tools and methods is discussed along with future considerations for research and planning practice.

Outcomes for women with co-occurring disorders and trauma: program and person-level effects.

Six-month outcomes are evaluated from a 9-site quasi-experimental study of women with mental health and substance use disorders who have experienced physical or sexual abuse who enrolled in either comprehensive, integrated, trauma-informed, and consumer/survivor/recovering person-involved services (N = 1023) or usual care (N = 983). Mental health, post-traumatic stress symptoms, and substance use outcomes are assessed with multilevel regression models, controlling for program and personal characteristics. Person-level variables predict outcomes independent of intervention condition and, to a small extent, moderate intervention and program effects. In sites where the intervention condition provided more integrated counseling than the comparison condition, there are increased effects on mental health and substance use outcomes; these effects are partially mediated by person-level variables. These results encourage further research to identify the longer-term effects of integrated counseling for women with co-occurring disorders and trauma histories.

Twelve-month outcomes of trauma-informed interventions for women with co-occurring disorders.

OBJECTIVE: Women with co-occurring mental health and substance use disorders frequently have a history of interpersonal violence, and past research has suggested that they are not served effectively by the current service system. The goal of the Women, Co-occurring Disorders, and Violence Study was to develop and test the effectiveness of new service approaches specifically designed for these women. METHODS: A quasi-experimental treatment outcome study was conducted from 2001 to 2003 at nine sites. Although intervention specifics such as treatment length and modality varied across sites, each site used a comprehensive, integrated, trauma-informed, and consumer-involved approach to treatment. Substance use problem severity, mental health symptoms, and trauma symptoms were measured at baseline, and follow-up data were analyzed with prospective meta-analysis and hierarchical linear modeling. RESULTS: A total of 2,026 women had data at the 12-month follow-up: 1,018 in the intervention group and 1,008 in the usual-care group. For substance use outcomes, no effect was found. The meta-analysis demonstrated small but statistically significant overall improvement in women's trauma and mental health symptoms in the intervention relative to the usual-care comparison condition. Analysis of key program elements demonstrated that integrating substance abuse, mental health, and trauma-related issues into counseling yielded greater improvement, whereas the delivery of numerous core services yielded less improvement relative to the comparison group. A few person-level characteristics were associated with increases or decreases in the intervention effect. These neither moderated nor supplanted the effects of integrated counseling. CONCLUSIONS: Outcomes for women with co-occurring disorders and a history of violence and trauma may improve with integrated treatment.

Heterosexual behavioral maintenance and change following HIV counseling and testing.

This study investigated heterosexual HIV risk behaviors, changes in stage of change for safer sex and factors associated with such changes, among a diverse sample of 560 heterosexually active individuals presenting at publicly funded HIV C&T sites. Questionnaires were administrated before HIV C&T, and three months afterwards. Positive serostatus was the most significant predictor of safer behavior after C&T. Many seronegative participants stopped sex with non-main partners. Behaviors with main partners were particularly resistant to change. Predictors of change varied by stage at pre-test. C&T services should tailor approaches and referrals based on stage of change and other client characteristics.

Public health needs and scientific opportunities in research on Latinas.

Much of the research on women's health has not deepened our understanding of health issues affecting Latinas. Yet integration of research on Latinas into the women's health agenda is important for at least 2 reasons. First, critical public health issues facing Latinas must be better understood if effective interventions designed to eliminate racial and ethnic disparities in health are to be developed and implemented. Second, studies on the health of Latinas represent unique opportunities to advance scientific understandings of underlying processes relevant to the health of other populations. Such research can further our knowledge of the processes underlying cultural adaptation and negotiation of changing sex roles and how these issues affect the health of women. Critical research and empirical approaches that help us to understand how race, ethnicity, sex, and class shape the health of Latinas will inform broader public health issues.
