This Stage II study is in response to NIDA's Behavioral Therapies Development Program (PA-99-107). A randomized clinical trial is proposed to evaluate the direct, mediated, and moderated effects of Integrated Family and Cognitive-Behavioral Therapy (IFCBT), a multisystems treatment for adolescent drug abuse with promising efficacy results. In the first study aim, we seek to evaluate the separate and possibly synergistic effects of family systems and cognitive-behavioral IFCBT components on posttreatment drug abuse problem severity, problem behavior, psychiatric distress, and academic achievement of adolescent drug abusers. Innovative analytic strategies are subsequently used to evaluate the degree to which successful outcomes are attributable to specific familial and cognitive-behavioral change processes targeted by IFCBT components. The possibility of effect-modification also is considered, with a focus on neurocognitive, psychiatric comorbidity, and demographic factors. Namely, we seek to understand how variations in specific client characteristics, such as executive dysfunctions or psychiatric comorbidity, might explain why treatments work for some drug abusing youths but not others. In addition to promising findings on IFCBT efficacy, this Stage II proposal benefits from the development and Stage I study application of (a) treatment manuals; (b) therapist training procedures; (c) therapist adherence and competence tools; (d) a neuropsychological battery to assess cognitive functions; (e) a psychodiagnostic battery to assess comorbid psychiatric disorders; and (f) a study assessment battery comprised of therapeutic process and outcome measures. This revised application has sought to address well-taken concerns cited by the reviewers while maintaining proposal strengths. The lack of adolescent drug treatment research continues to be a serious gap in the addictions literature despite alarmingly high rates of drug abuse among youth and the range of morbidities and mortality that result nationwide. If successful, this project should help to identify specific behavior change processes targeted by family systems and cognitive-behavioral treatments that foster subsequent reductions in drug use and problem behavior among recovering youth. Neurocognitive and psychiatric influences on adolescent drug treatment outcomes appear to be significant yet are poorly understood. Increasing our understanding of relationships between client characteristics, skill development during treatments, and subsequent outcomes should also help to improve adolescent drug treatments.
The purpose of this R01 study is to evaluate the association between neuropsychological executive dysfunction and HIV infection among young injection and non-injection drug users. A longitudinal study will be conducted in which the cohort of seronegative drug users completing a baseline neuropsychological battery are re-assessed on three subsequent occasions, roughly six months apart. The primary aim of the longitudinal study is to estimate the magnitude of the suspected causal relationship between executive dysfunction and HIV-risk behaviors while adjusting for time-invariant (e.g. sex, ethnicity) and time-varying (e.g. degree of drug abuse) covariates. We also seek to evaluate: (1) the degree to which specific executive dysfunctions predispose heroin and cocaine users to high-risk injection practices or sex behaviors, and (2) whether observed relationship between executive dysfunction and HIV-risk behaviors can be understood independent of levels of drug -taking frequency, or whether the observed data are more consistent with complex patterns of interdependency between executive dysfunction, drug-taking frequency, and HIV-risk-behaviors. If successful, this project will shed new light on significant and potentially malleable HIV-risk factors in injection and non-injection drug users. This will be important evidence because injection drug abuse continues to account for a large proportion of HIV seroconversions particularly among young women and minorities. As such, this RO1 research project serves as an important initial step in a line of innovative investigations about suspected causal associations between neuropsychological deficits and HIV-risk behaviors in drug users. Ultimately, this line of investigation should lead to changes in public and clinical practices designed to prevent HIV infection.
The overall goal of the research project is to improve the outcome of medical care for injection drug users (IDUs) with Hepatitis C viral (HCV) infection. Hypothesis: An intervention designed to improve the rate of HCV treatment completion and sustained virologic response (SVR) in IDUs will increase access by integrating HCV medical care into a substance abuse treatment program.
