ABSTRACT

This article presents the main outcome findings from two inter-related randomized trials conducted at four sites to evaluate the effectiveness and cost-effectiveness of five short-term outpatient interventions for adolescents with cannabis use disorders. Trial 1 compared five sessions of Motivational Enhancement Therapy plus Cognitive Behavioral Therapy (MET/CBT) with a 12-session regimen of MET and CBT (MET/CBT12) and another that included family education and therapy components (Family Support Network [FSN]). Trial II compared the five-session MET/CBT with the Adolescent Community Reinforcement Approach (ACRA) and Multidimensional Family Therapy (MDFT). The 600 cannabis users were predominately white males, aged 15-16. All five CYT interventions demonstrated significant pre-post treatment during the 12 months after random assignment to a treatment intervention in the two main outcomes: days of abstinence and the percent of adolescents in recovery (no use or abuse/dependence problems and living in the community). Overall, the clinical outcomes were very similar across sites and conditions; however, after controlling for initial severity, the most cost-effective interventions were MET/CBT5 and MET/CBT12 in Trial 1 and ACRA and MET/CBT5 in Trial 2. It is possible that the similar results occurred because outcomes were driven more by general factors beyond the treatment approaches tested in this study; or because of shared, general helping factors across therapies that help these teens attend to and decrease their connection to cannabis and alcohol.

    • "To facilitate clinical comparison with adolescents, Smith, Godley, Godley, and Dennis (2011) examined both emerging adult and adolescent response to the Adolescent Community Reinforcement Approach (A-CRA) provided at one of several SAMHSA-funded outpatient treatment programs, using propensity score matching to create groups that were roughly equivalent on key characteristics associated with positive outcomes (e.g., treatment retention). A-CRA is a CB intervention for SUD, shown to be effective in the treatment of cannabis use disorders among adolescents (Dennis et al., 2004; Godley et al., 2001). Authors found that although both groups improved from intake to follow-up (3 or 6 months post-intake), emerging adults had significantly worse treatment response. "

    ABSTRACT: Substance use and substance-related disorders are among the most prodigious public health problems in the United States. Emerging adults (ages 18–25) appear to carry a disproportionately large share of this societal burden, as they are more than twice as likely as adolescents and older adults to be diagnosed with substance use disorders (SUD), and comprise more than 20% of SUD treatment seekers. Described as the "age of feeling in-between," emerging adulthood is associated with a biopsychosocial profile distinct from both adolescence and older adulthood, making members of this age group unique and challenging clinical cases. Data suggest that although emerging adults can benefit from cognitive-behavioral (CB) and other psychosocial treatments for SUD, they are likely to have poorer treatment response than their younger and older counterparts. Therefore, we propose several theoretically and empirically-grounded treatment modifications for this vulnerable group, such as parent counseling (or "coaching") to facilitate better treatment engagement and benefit via contingency management. A case example is used to illustrate challenges typical in SUD treatment for emerging adults and how a CB practitioner might choose to modify his/her approach based on the proposed modifications. We also offer several recommendations for practitioners who wish to address their patients' substance misuse or SUD when it is not the primary focus of treatment.

    • "Current outpatient treatment practices for adolescent substance abusers utilize cognitive-behavioral (CB)-based therapies for relapse prevention (Dennis et al., 2002, 2004; Kaminer, 2001). During group therapy, youth are taught to self-monitor and identify affect, cognitions, and situational factors that make them vulnerable to relapse. "

    ABSTRACT: Outpatient treatment practices for adolescent substance users utilize retrospective self-report to monitor drug use. Cell phone-based ecological momentary assessment (CEMA) overcomes retrospective self-report biases and can enhance outpatient treatment, particularly among Latino adolescents, who have been understudied with regard to CEMA. This study explores compliance to text message-based CEMA with youth (n = 28; 93% Latino) in outpatient treatment. Participants were rotated through daily, random, and event-based CEMA strategies for 1-month periods. Overall compliance was high (>80%). Compliance decreased slightly over the study period and was less during random versus daily strategies and on days when alcohol use was retrospectively reported. Findings suggest that CEMA is a viable monitoring tool for Latino youth in outpatient treatment, but further study is needed to determine optimal CEMA strategies, monitoring time periods, and the appropriateness of CEMA for differing levels of substance use.

    • "The mood module featured behavioral activation strategies, which have shown promise as easily understood and efficacious in the treatment of depression (Hopko, Lejuez, Ruggiero, et al., 2003; Jacobson et al., 1996; Ruggiero et al., 2007). The tobacco and alcohol modules used brief motivational-enhancement and cognitive– behavioral strategies (Dennis et al., 2004; Waldron & Kaminer, 2004). These strategies are evidence based and were intended to address the needs of adolescent populations, such as teaching skills to (a) refuse substance abuse offers from peers; (b) establish a positive family and peer network that is supportive of abstention from use; (c) develop a plan for positive, enjoyable activities to replace substance use– related activities; and (d) cope with stressful and/or high-risk situations (Sampl & Kadden, 2001).

    ABSTRACT: Although Web-based treatments have significant potential to assess and treat difficult-to-reach populations, such as trauma-exposed adolescents, the extent that such treatments are accessed and used is unclear. The present study evaluated the proportion of adolescents who accessed and completed a Web-based treatment for postdisaster mental health symptoms. Correlates of access and completion were examined. A sample of 2,000 adolescents living in tornado-affected communities was assessed via structured telephone interview and invited to a Web-based treatment. The modular treatment addressed symptoms of posttraumatic stress disorder, depression, and alcohol and tobacco use. Participants were randomized to experimental or control conditions after accessing the site. Overall access for the intervention was 35.8%. Module completion for those who accessed ranged from 52.8% to 85.6%. Adolescents with parents who used the Internet to obtain health-related information were more likely to access the treatment. Adolescent males were less likely to access the treatment. Future work is needed to identify strategies to further increase the reach of Web-based treatments to provide clinical services in a postdisaster context.
