Retention and Treatment Outcome of Youth with Cannabis Use Disorder Referred By the Legal System

Systematic review of treatment completion rates and correlates among young people accessing alcohol and other drug treatment

BACKGROUND AND AIMS

Treatment completion is associated with improved alcohol and other drug (AOD) treatment outcomes. Unfortunately, treatment disengagement is common, particularly among young people. We reviewed and synthesised research on AOD treatment completion and/or early disengagement among young people.

METHODS

We conducted a systematic review and meta-analysis of studies reporting on completion rates and/or early disengagement from psychosocial AOD treatment among adolescents and young adults. An overall estimated treatment completion rate was calculated using inverse-variance random effects meta-analysis, and random-effects meta-regression was used to identify between-study level moderators of completion rate. We completed a narrative review summarising literature on early treatment disengagement and within-study level correlates of treatment completion. Study quality was assessed using the EPHPP.

RESULTS

Of the 6158 studies screened, we retained 410 for full text review and included 98 studies in the review. Treatment completion rates were reported in 88 studies, and early disengagement rates were reported in 13. The estimated overall treatment completion rate was 59 % (95 % CI=57-61 %), with experimental studies reporting higher rates of completion than observational studies. There was limited evidence for demographic or substance-related correlates of treatment completion. Contingency management was associated with increased completion rates, as was family-based intervention.

CONCLUSIONS

Disengagement from AOD treatment among youth populations is common and contributes to poor treatment outcomes. Existing research has yielded little consensus on the factors associated with treatment completion. The use of contingency management strategies and involving family/social supports in treatment were identified as potential avenues for promoting ongoing treatment engagement.

Barriers for recruitment to treatment of youths with co-occurring substance use disorders and depression

BACKGROUND AND OBJECTIVES

Recruitment challenges for treatment trials of adolescents with substance use disorder (SUD) and co-occurring depression (COD) have not been reported. The objective is to examine whether recruitment and engagement during the pretreatment assessment phase differ between adolescents in a SUD-COD versus SUD-only treatment study.

METHODS

A similar recruitment approach compared five-stage progressions in the pretreatment phase between a SUD-only (n = 252) and SUD-COD (n = 212) study. We examined the "gradient" of recruitment and retention along four stages after referral/inquiries; (a) screening for eligibility by phone, (b) meeting eligibility in an interview, (c) completion of baseline assessment, and (d) participation in the first psychotherapy session of each study.

RESULTS

Compared to SUD-only, the retention of adolescents with SUD-COD was significantly poorer from referral/inquiry to all subsequent stages. In particular, the odds ratio and 95% confidence interval from referral/inquiry to screening for eligibility by phone, meeting eligibility in an interview, completion of baseline assessment, and participation in the first psychotherapy session were all less than one. Male attrition rates were slightly higher than females but were not statistically significant.

DISCUSSION AND CONCLUSIONS

A high proportion of referred adolescents did not meet the study criteria. This indicates a need to examine (1) potential strategies for overcoming recruitment challenges in adolescents and their engagement in the pretreatment phase for studies of COD and (2) baseline variables for predictors and moderators for adequately powered studies.

SCIENTIFIC SIGNIFICANCE

This is the first study to assess recruitment challenges for adolescents with COD.

Treatment completion among justice-involved youth engaged in behavioral health treatment studies in the United States: A systematic review and meta-analysis

Justice-involved youth (JIY) have high rates of behavioral health disorders, but few can access, much less complete, treatment in the community. Behavioral health treatment completion among JIY is poorly understood, even within treatment studies. Measurement, reporting, and rates of treatment completion vary across studies. This systematic review and meta-analysis synthesizes the literature on rates of treatment completion among JIY enrolled in research studies and identifies potential moderators. After systematically searching 6 electronic databases, data from 13 studies of 20 individual treatment groups were abstracted and coded. A meta-analysis examined individual prevalence estimates of treatment completion in research studies as well as moderator analyses. Prevalence effect sizes revealed high rates of treatment completion (pr = 82.6). However, analysis suggests a high likelihood that publication bias affected the results. Treatment groups that utilized family- or group-based treatment (pr = 87.8) were associated with higher rates of treatment completion compared to treatment groups utilizing individual treatment (pr = 61.1). Findings suggest that it is possible to achieve high rates of treatment completion for JIY, particularly within the context of family- and group-based interventions. However, these findings are limited by concerns about reporting of treatment completion and publication bias.

Racial and Ethnic Disparities, Referral Source and Attrition From Outpatient Substance Use Disorder Treatment Among Adolescents in the United States

The following study examined the association between race, ethnicity, referral source, and reasons for attrition from substance use treatment in a sample of 72,643 discharges of adolescent youth in the United States from 2014 to 2016. Black and Hispanic adolescents were more likely to be discharged due to incarceration and termination by the facility compared to White adolescents. Adolescents referred by probation, diversion, other juvenile justice organizations, health care providers, community agencies, and individual referrals were significantly more likely to be discharged due to incarceration and terminated by the treatment facility compared to youth who were referred by schools. Findings suggest that enhancing linkage to treatment from systems in the social environment may play a role in attenuating racial and ethnic disparities in rates of attrition from substance abuse treatment among adolescent youth in the United States.
