Potential pathways from childhood sexual abuse (CSA) to negative self-schemas to subsequent dissociative symptoms and low global self-esteem were examined in a prospective longitudinal study of 160 ethnically diverse youth with confirmed CSA histories. Participants were interviewed at the time of abuse discovery, when they were 8 to 15 years of age, and again 1 and 6 years later. Abuse-specific indicators of stigmatization, in particular the combination of shame and self-blame more than general self-blame attributions for everyday events, explained which youth with CSA histories experienced more dissociative symptoms and clinically significant levels of dissociation. Abuse-specific stigmatization was found to operate as a prospective mechanism for subsequent dissociative symptoms but not self-esteem.

Previous studies demonstrated the relationship between consensus among both staff and clients with client engagement in treatment and between client consensus and 1-year treatment outcomes. The present article explores the correlates of staff consensus, defined as the level of agreement among staff as to the importance of treatment activities in their program, using a national sample of 80 residential substance abuse treatment programs. Constructive conflict resolution had the largest effect on consensus. Low client-to-staff ratios, staff education, and staff experience in substance abuse treatment were also significantly related to consensus. Frequency of training, an expected correlate of consensus, was negatively associated with consensus, whereas frequency of supervision was not a significant correlate. The implications of the findings for future research and program improvement are discussed.

Potential pathways from childhood sexual abuse (CSA) to subsequent romantic intimacy problems were examined in a prospective longitudinal study of 160 ethnically diverse youth with confirmed CSA histories. Participants were interviewed at the time of abuse discovery, when they were 8-15 years of age, and again 1-6 years later. Stigmatization (abuse-specific shame and self-blame) and internalizing symptoms (posttraumatic stress and depressive symptoms), more than abuse severity, explained which youth with CSA histories experienced more sexual difficulties and dating aggression. Stigmatization was found to operate as a predictive mechanism for subsequent sexual difficulties. Internalizing symptoms were not predictive of romantic intimacy problems, although they did show correlational relations with sexual difficulties and dating aggression. Early interventions such as trauma-focused cognitive-behavioral therapy that target stigmatization may be important for preventing the development of sexual difficulties in CSA youth.

The present study examines the relationship between substance use, mental health problems, and violence in a sample of offenders released from prison and referred to substance abuse treatment programs. Data from 34 sites (n = 1,349) in a federally funded cooperative, the Criminal Justice Drug Abuse Treatment Studies (CJDATS), were analyzed. Among parolees referred to substance abuse treatment, self-reports for the six-month period before the arrest resulting in their incarceration revealed frequent problems with both substance use and mental health. For most offenders with substance use problems, the quantity of alcohol consumed and the frequency of drug use were associated with a greater probability of self-reported violence. Mental health problems were not indicative of increases in violent behavior, with the exception of antisocial personality problems, which were associated with violence. The paper emphasizes the importance of providing substance abuse treatment in relation to violent behavior among offenders with mental health problems being discharged to the community.

This research presents estimates of HIV prevalence rates among injection drug users (IDUs) in large US metropolitan statistical areas (MSAs) during 1992-2002. Trend data on HIV prevalence rates in geographic areas over time are important for research on determinants of changes in HIV among IDUs. Such data also provide a foundation for the design and implementation of structural interventions for preventing the spread of HIV among IDUs. Our estimates of HIV prevalence rates among IDUs in 96 US MSAs during 1992-2002 are derived from four independent sets of data: (1) research-based HIV prevalence rate estimates; (2) Centers for Disease Control and Prevention Voluntary HIV Counseling and Testing data (CDC CTS); (3) data on the number of people living with AIDS compiled by the CDC (PLWAs); and (4) estimates of HIV prevalence in the US. From these, we calculated two independent sets of estimates: (1) calculating CTS-based Method (CBM) using regression adjustments to CDC CTS; and (2) calculating the PLWA-based Method (PBM) by taking the ratio of the number of injectors living with HIV to the numbers of injectors living in the MSA. We take the mean of CBM and PBM to calculate over all HIV prevalence rates for 1992-2002. We evaluated trends in IDU HIV prevalence rates by calculating estimated annual percentage changes (EAPCs) for each MSA. During 1992-2002, HIV prevalence rates declined in 85 (88.5%) of the 96 MSAs, with EAPCs ranging from -12.9% to -2.1% (mean EAPC=-6.5%; p<0.01). Across the 96 MSAs, collectively, the annual mean HIV prevalence rate declined from 11.2% in 1992 to 6.2 in 2002 (EAPC, -6.4%; p<0.01). Similarly, the median HIV prevalence rate declined from 8.1% to 4.4% (EAPC, -6.5%; p<0.01). The maximum HIV prevalence rate across the 11 years declined from 43.5% to 22.8% (EAPC, -6.7%; p<0.01). Declining HIV prevalence rates may reflect high continuing mortality among infected IDUs, as well as primary HIV prevention for non-infected IDUs and self-protection efforts by them. These results warrant further research into the population dynamics of disease progression, access to health services, and the effects of HIV prevention interventions for IDUs.

This study examined the relationships between substance abuse, mental health problems and HIV risk behavior in offenders discharged from prison and referred to substance abuse treatment programs. Data from 34 sites (n = 1,358) in a federally-funded cooperative agreement, the Criminal Justice Drug Abuse Treatment Studies (CJDATS), were analyzed. Among parolees referred to substance abuse treatment, self reports for the six-month period before the arrest resulting in their incarceration revealed frequent problems with both substance use and mental health. HIV risk behavior was operationalized as either (a) unsafe injection drug use, e.g., sharing needles and/or sharing injection equipment, or (b) unsafe sex, e.g., sex without a condom. The findings were that (1) unsafe injection drug use was associated with unsafe sex and vice versa, (2) unsafe sex behavior was related to frequency of drug use, and (3) unsafe sex behavior was related to frequency of alcohol use. In these samples, mental health problems did not have a significant effect on risk behavior, controlling for other variables. Future research should probe this "nonfinding" using standardized diagnostic and symptom measures to provide greater detail on the mental health problems (e.g., age of onset, frequency, and severity of the problem).

We examined the risk and protective factors and mental health problems of 105 low SES, urban adolescents whose mothers were coping with alcohol abuse and other drug problems. Approximately half of the mothers were also HIV-infected. As hypothesized, there were few differences between adolescents of HIV-infected and HIV-uninfected mothers in background characteristics, mental health issues and current substance use risk behaviors. In addition to maternal substance abuse, youth in both groups experienced similar risk factors including early foster care placement and high levels of maltreatment. Current patterns of emerging risk behaviors were evident among youth in both groups as well as signs of resiliency including high levels of school attendance. These results underscore the importance of interventions for youth of substance abusing mothers, particularly those living in urban poverty.

This article evaluates the efficacy of a 14-session social-cognitive behavioral intervention on problem drinking (and where applicable, drug use) among urban HIV-infected and uninfected mothers, in comparison to a single-session social/motivational intervention, and explores the relationships of initial substance use problem severity and HIV status to efficacy. A randomized controlled trial design was used. Participants (N = 118) were mothers with problem drinking, both HIV-infected (55%) and uninfected, and primarily from racial/ethnic minority and low socioeconomic status backgrounds. Participants were interviewed five times over 18 months. Both intervention arms yielded reductions in alcohol and drug use frequency, alcohol quantity, and alcohol/drug problems, with moderate effect sizes. Those with greater initial substance use maintained reductions over a longer period of time in response to the more intensive social-cognitive intervention. Treatment efficacy did not vary by HIV status. The utility of targeting intervention intensity to the level of substance use is supported.

Organizational culture, as evinced by consensus regarding staff and client beliefs and values, has been shown to affect client engagement in residential substance abuse treatment. The present paper extends this work to treatment outcomes. Secondary analysis of data from a "Beliefs About Abstinence Scale," used in the Drug Abuse Treatment Outcomes Study (DATOS), was conducted for 76 programs, including outpatient methadone treatment, outpatient drug-free, short-term inpatient, and long-term residential programs. Findings show that higher levels of client consensus after 1 month of treatment were associated with less use of drugs and alcohol at 1-year follow-up, after controlling for the mean of the scale score, gender, age, client substance use at baseline and treatment modality. The implications of the results for substance abuse treatment are discussed.

Despite considerable effort to develop matching strategies and client placement protocols, research studies fail to yield compelling results regarding the benefits of matching to treatment. The most consistent findings suggest a matching paradigm, which defines a successful placement as the least treatment intensity required addressing the severity of the disorder. The purpose of the present study is to provide further empirical support for the validity of a severity-intensity paradigm utilizing data from the Drug Abuse Treatment Outcome Studies. A 'passive match' approach employed the Client Matching Protocol decision algorithm, which recommended clients to long-term residential or outpatient drug-free treatment. One-year outcomes for clients matched to long-term residential treatment were better on all outcome variables compared to those undertreated in outpatient drug-free treatment. Findings supported the validity of the severity-intensity paradigm in that undertreated clients showed less improvement compared to matched and overtreated clients
