Evidence-Based Psychosocial Treatments for Adolescent Substance Abuse

This review synthesized findings from 17 studies since 1998 regarding evaluation of outpatient treatments for adolescent substance abuse. These studies represented systematic design advances in adolescent clinical trial science. The research examined 46 different intervention conditions with a total sample of 2,307 adolescents. The sample included 7 individual cognitive behavior therapy (CBT) replications (n = 367), 13 group CBT replications (n = 771), 17 family therapy replications (n = 850) and 9 minimal treatment control conditions (n = 319). The total sample was composed of approximately 75% males, and the ethnic/racial distribution was approximately 45% White, 25% Hispanic, 25% African American, and 5% other groups. Meta-analysis was used to evaluate within-group effect sizes as well as differences between active treatment conditions and the minimal treatment control conditions. Methodological rigor of studies was classified using Nathan and Gorman (2002) criteria, and treatments were classified using criteria for well-established and probably efficacious interventions based on Chambless et al. (1996). Three treatment approaches, multidimensional family therapy, functional family therapy, and group CBT emerged as well-established models for substance abuse treatment. However, a number of other models are probably efficacious, and none of the treatment approaches appeared to be clearly superior to any others in terms of treatment effectiveness for adolescent substance abuse.

Ethnic Matching and Treatment Outcome With Hispanic and Anglo Substance-Abusing Adolescents in Family Therapy

This study examined treatment outcomes of 86 highly acculturated Hispanic and Anglo substance-abusing adolescents in functional family therapy, testing the hypothesis that ethnic matching of therapist and client is related to better treatment outcomes for clients. Adolescents reported on their substance use pre- and posttreatment on a timeline follow-back interview. Ethnically matched Hispanic adolescents demonstrated greater decreases in their substance use compared with Hispanic adolescents with Anglo therapists. Ethnic match status was not related to treatment outcome for Anglo clients. Thus, the matching hypothesis was supported for Hispanic clients only. The results underscore the importance of greater ethnic diversity among therapists and better cultural competency training for Anglo therapists. More research is needed on individual differences in the effects of ethnic matching.

Ethnic Background, Therapeutic Alliance, and Treatment Retention in Functional Family Therapy With Adolescents Who Abuse Substances

In this study, the authors examined the role of balance between adolescent-therapist and parent-therapist alliances in the retention of functional family therapy clients. Therapeutic alliances of mothers, fathers, and adolescents were assessed from videotapes of the 1st treatment session for 43 Hispanic and 43 Anglo families. Hispanic families who dropped out before completing the requisite number of sessions were found to have greater imbalance in alliance (parent-adolescent) than those who did complete therapy. However, this finding was not replicated with Anglo families. Results are interpreted in terms of previous research on family-level balanced alliance effects.

Adolescent Health-Risk Sexual Behaviors: Effects of a Drug Abuse Intervention

Adolescents who abuse substances are more likely to engage in health-risking sexual behavior (HRSB) and are at particularly high risk for HIV/AIDS. Thus, substance abuse treatment presents a prime opportunity to target HIV-risk behaviors. The present study evaluated a one-session HIV-risk intervention embedded in a controlled clinical trial for drug-abusing adolescents. The trial was conducted in New Mexico and Oregon with Hispanic and Anglo adolescents. Youths were randomly assigned to individual cognitive behavior therapy (CBT) or to an integrated behavioral and family therapy (IBFT) condition, involving individual and family sessions. The HIV-specific intervention was not associated with change. IBFT and CBT were both efficacious in reducing HIV-risk behaviors from intake to the 18-month follow-up for high-risk adolescents. For low-risk adolescents, CBT (versus IBFT) was more efficacious in suppressing HRSB. These data suggest that drug abuse treatments can have both preventative and intervention effects for adolescents, depending on their relative HIV-risk.ResumenLos adolescentes que abusan de sustancias tienen más probabilidades de involucrarse en comportamientos sexuales de riesgo (HRSB) y están en riesgo particularmente alto de VIH/SIDA. Por lo tanto, el tratamiento de abuso de sustancias presenta una oportunidad única para orientar los comportamientos de riesgo de VIH. El presente estudio evaluó una intervención de un período de sesiones de riesgo de VIH en un ensayo clínico aleatorio para el tratamiento de toxicómanos adolescentes. El ensayo se llevó a cabo tanto en Nuevo México y Oregon, con adolescentes hispanos y anglos, con evaluaciones al inicio, después del tratamiento y seguimiento. Los jóvenes fueron asignados aleatoriamente a dos tipos de tratamiento basado en la evidencia, una terapia individual cognitivoconductual (TCC) o un tratamiento integrado del TCC y Terapia de Familia Funcional (es decir, IBFT) con sesiones individuales y familiares. Los resultados mostraron que la intervención específicas para el VIH no se asoció con el cambio. Sin embargo, IBFT y TCC fueron eficaces en la reducción de conductas de riesgo de VIH a partir del consumo de los adolescentes de 18 meses de seguimiento de alto riesgo. Para los adolescentes de bajo riesgo, la TCC fue más eficaz en la supresión de HRSB en comparación con IBFT. Estos datos sugieren que los tratamientos del abuso de drogas puede tener efectos preventivos y de intervención de los adolescentes, en función de su relación de riesgo de VIH.

Assertive Outreach Strategies for Narrowing the Adolescent Substance Abuse Treatment Gap: Implications for Research, Practice, and Policy

In any given year, only about 10% of the nearly two million adolescents exhibiting substance abuse or dependence in the United States receive substance abuse treatment. Given this state of affairs, it is unlikely that the massive effort and expenditure of resources over the past decade on developing, testing, and disseminating effective treatments for adolescent substance abuse will have an appreciable impact on the prevalence of substance use disorders among the adolescent population. In order to substantially diminish the pervasive gap between levels of need for and utilization of adolescent substance abuse treatment, specialized assertive outreach strategies may be needed. This paper outlines a framework for assertive outreach for adolescents with substance use disorders and proposes specific types of strategies for identifying and enrolling such adolescents into treatment. Implications for practice and policy pertaining to adolescent substance abuse treatment service delivery are considered.

Sequenced versus coordinated treatment for adolescents with comorbid depressive and substance use disorders.

OBJECTIVE We evaluated 3 methods of integrating interventions for depression (Adolescent Coping With Depression Course; CWD) and substance use disorders (Functional Family Therapy; FFT), examining (a) treatment sequence effects on substance use and depression outcomes and (b) whether the presence of major depressive disorder (MDD) moderated effects. METHOD Participants were 170 adolescents (ages 13-18; 22% female; 61% non-Hispanic White) with comorbid depressive disorder (54% MDD, 18% dysthymia) and substance use disorders who were randomized to (a) FFT followed by CWD (FFT/CWD), (b) CWD followed by FFT (CWD/FFT), or (c) coordinated FFT and CWD (CT). Acute treatment (24 treatment sessions provided over 20 weeks) and 6- and 12-month follow-up effects are presented for substance use (percentage of days of substance use; Timeline Followback) and depression (Childrens Depression Rating Scale-Revised). RESULTS FFT/CWD achieved better substance use outcomes than CT at posttreatment, and 6- and 12-month follow-ups; substance use effects for CWD/FFT were intermediate. For participants with baseline MDD, the CWD/FFT sequence resulted in lower substance use than either FFT/CWD or CT. Depressive symptoms decreased significantly in all 3 treatment sequences with no evidence of differential effectiveness during or following treatment. Attendance was lower for the second of both sequenced interventions. A large proportion of the sample received treatment outside the study, which predicted better outcomes in the follow-up. CONCLUSIONS Depression reductions occurred early in all 3 treatment sequences. Of the examined treatment sequences, FFT/CWD appeared most efficacious for substance use reductions but addressing depression early in treatment may improve substance use outcomes in the presence of MDD.

Depression Change Profiles in Adolescents Treated for Comorbid Depression/Substance Abuse and Profile Membership Predictors

Using data from a randomized trial in which adolescents with depressive and substance use disorders (SUD) received treatments for both disorders in either a sequenced or coordinated manner, we (a) determine the number and nature of depression response profiles through 1-year posttreatment and (b) examine whether 8 previously identified factors predict profile membership. There were 170 adolescents (M age = 16.4 years; 22% female; 28% Hispanic, 61% Non-Hispanic White) with comorbid depressive disorder/SUD randomized to one of three sequences of receiving the Adolescent Coping With Depression Course and Functional Family Therapy for SUD (depression treatment followed by SUD treatment; SUD treatment followed by depression treatment; coordinated treatment). Depression was assessed at 7 points from baseline to 1-year follow-up. A 4-class solution fit the data best, with groups labeled Mildly Depressed Responders (57.1%), Depressed Responders (18.8%), Depressed Non-Responders (12.9%), and Depressed with Recurrence (11.2%). The 4 change profiles differed on indices of all but 1 predictor (age); most differences were driven by lower scores among Mildly Depressed Responders. Profile membership was most strongly predicted by depression severity, cognitive distortions, hopelessness, and global functioning. The strongest predictor of Nonresponse was low family cohesion, whereas Recurrence was associated with hopelessness, suicide attempts, and starting treatment near the end of the school year. Most depressed adolescents experienced a positive response that was maintained. Understanding the most common profiles of depression change during and following treatment and the variables that predict change can help improve treatment outcomes and advance tailoring efforts.
