Abstract Meta-analysis was used to synthesize research on the effects of outpatient treatment on substance use outcomes for adolescents with substance use disorders. An extensive literature search located 45 eligible experimental or quasi-experimental studies reporting 73 treatment-comparison group pairs, with many of the comparison groups also receiving some treatment.
The first analysis examined effect sizes for the substance use outcomes of adolescents receiving different types of treatment relative to the respective comparison groups. As a category, family therapy programs were found to be more effective than their comparison conditions, whereas no treatment programs were less effective.
However, not all treatment types were compared with each other in the available research, making it difficult to assess the comparative effectiveness of the different treatments. To provide a more differentiated picture of the relative improvement in substance use outcomes for different treatments, a second analysis examined pre-post effect sizes measuring changes in substance use for adolescents in the separate treatment and comparison arms of the studies.
The adolescents in almost all types of treatment showed reductions in substance use. The greatest improvements were found for family therapy and mixed and group counseling. Longer treatment duration was associated with smaller improvements, but other treatment characteristics and participant characteristics had little relationship to the pre-post changes in substance use.
Based on these findings family therapy is the treatment with the strongest evidence of comparative effectiveness, although most types of treatment appear to be beneficial in helping adolescents reduce their substance use.
With such large numbers of adolescents in substance abuse treatment, it is important to know whether such treatments are effective and, if they are not all equally effective, which are most effective. The study reported here uses meta-analysis to investigate the findings of experimental and quasi-experimental studies that compare different outpatient substance abuse treatments for adolescents with control conditions or with each other.
Research on Treatment Effectiveness for Adolescents Adolescents with substance use disorders differ from their adult counterparts in several ways and thus may have different treatment needs Winters, That the causes and consequences of substance use disorders may differ for adolescents and adultsimplies that evidence regarding the effectiveness of treatment for adolescents should be based on research conducted with adolescents, not inferred from research with adults.
The number of studies focusing specifically on the effectiveness of adolescent substance abuse treatment has burgeoned over the last decade Dennis et al.
A few previous attempts have been made to systematically summarize the results of this research in order to assess the extent to which treatment for adolescents is effective and which types of treatment are most effective.
Some of these reviews have included studies of both adults and adolescents, leaving ambiguity about whether the results can be applied specifically to adolescents. One of the earliest meta-analyses of alcohol treatment studies, for instance, found brief interventions and motivational enhancement programs to be most effective, but did not differentiate effects for adults and adolescents Miller et al.
Other meta-analyses that combined results for adults and adolescents examined only one or two specific treatment types and therefore had limited scope, though they reported beneficial effects for the treatments reviewed.
Another found that methadone maintenance treatment reduced opiate use and criminal activities Marsch, While these reviews are informative, whether the same conclusions would apply specifically to adolescents with substance use disorders is unclear. Among the reviews focused exclusively on treatment for adolescents, some were traditional narrative reviews that did not characterize treatment effects in a way that allowed them to be compared.
Deas and ThomasWaldronWeinberg et al. Other narrative reviews were restricted to randomized trials and did not consider whether strong quasi-experimental studies provided useful evidence e.
The only relatively comprehensive systematic review specifically of outpatient adolescent substance abuse treatment effectiveness to date is the meta-analysis conducted by Waldron and Turner of findings from 17 randomized clinical trials and the 46 treatment conditions embedded within them.
Their results showed generally beneficial treatment effects that were especially positive for Multidimensional Family Therapy, Functional Family Therapy, and cognitive behavioral therapy. Analysis of treatment differences, however, was restricted to these three treatment modalities.
Further, by focusing only on randomized trials, this meta-analysis excluded the larger body of studies using quasi-experimental research designs.
Though the latter must be interpreted with care because of their methodological vulnerabilities, they may nonetheless provide useful information about the nature and range of treatment effects that adds to that available from the limited number of randomized studies. The Current Study In an attempt to more fully synthesize the adolescent substance abuse treatment effectiveness literature, the current study addresses three broad research questions.
