Adolescent Outpatient and Continuing Care Study (AOCCS)

August 13, 2013 updated by: Chestnut Health Systems
The purpose of this study was to evaluate the effectiveness and cost-effectiveness of two types of outpatient treatment with and without Assertive Continuing Care (ACC) for 320 adolescents with substance use disorders. Study participants were randomly assigned to one of four conditions: (a) Chestnut's Bloomington Outpatient Treatment (CBOP) without ACC; (b) CBOP with ACC; (c) Motivational Enhancement Therapy/Cognitive Behavior Therapy-7 session model (MET/CBT7) without ACC; and (d) MET/CBT7 with ACC. Based on prior quasi and experimental studies, the investigators hypothesized that MET/CBT would be more effective and cost-effective than CBOP in terms of increasing days abstinent and decreasing substance abuse problems. Additionally, the investigators hypothesized that the groups receiving ACC would have significantly better outcomes than the groups without ACC. Lastly, the investigators hypothesized that adding ACC to MET/CBT would be the most cost-effective option in terms of days abstinent.

Detailed Description

This study evaluated the effectiveness and cost-effectiveness of two types of outpatient treatment with and without Assertive Continuing Care (ACC) for 320 adolescents with substance use disorders. Study participants were randomly assigned to one of four conditions: (a) Chestnut's Bloomington Outpatient Treatment (CBOP) without ACC; (b) CBOP with ACC; (c) Motivational Enhancement Therapy/Cognitive Behavior Therapy-7 session model (MET/CBT7) without ACC; and (d) MET/CBT7 with ACC. All study conditions attained high rates of participant engagement and retention. Follow-up interviews were completed with over 90% of the adolescents at three, six, nine, and 12 months after treatment admission. There was a significant time by condition effect over 12 months, with CBOP having a slight advantage for average percentage of days abstinent. Unlike previous findings that ACC provided incremental effectiveness following residential treatment, there were no statistically significant findings with regard to the incremental effectiveness of ACC following outpatient treatment. Analysis of the costs of each intervention combined with its outcomes revealed that the most cost-effective condition was MET/CBT7 without ACC.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

12 years to 18 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • 12-18 years old
  • met ASAM's (2001) Patient Placement Criteria for Level I outpatient treatment based on a substance abuse or dependence diagnosis and six dimensional admission criteria (i.e., severity of intoxication/withdrawal, physical health, emotional/behavioral health, treatment readiness, relapse potential, and recovery environment)
  • attended an admission appointment

Exclusion Criteria:

  • "stepped-down" from residential treatment and were therefore more severe than adolescents who entered outpatient treatment from the community
  • were recommended only for individual counseling, as both outpatient treatment conditions had group components
  • were a ward of the state
  • did not have a parent/guardian present during admission to outpatient treatment
  • appeared to have insufficient mental capacity to provide informed consent
  • did not speak English with sufficient ability to understand study procedures and instruments

Intervention / Treatment

Experimental: CBOP without ACC
Behavioral: Chestnut Bloomington Outpatient (CBOP)
CBOP is an evidence-informed intervention that has developed over 20 years and been shaped by treatment research. The underlying theory of change is that the combination of multiple evidence-based and best-practice treatment components will increase the adolescent's desire to change, provide the necessary skills, and create an environment supportive for this change. The intervention is based on a manual and is primarily delivered through skill and therapy groups, combined with a limited number of family and individual sessions for treatment planning and progress reviews.

Behavioral: Assertive Continuing Care (ACC)
ACC is a home-based continuing care approach that takes place over a 12-14 week period and has shown promise in a randomized clinical trial of adolescents discharged from residential treatment. Following an operant reinforcement and skills training model, ACC combines the Adolescent Community Reinforcement Approach and case management services to help adolescents and their caregivers engage in prosocial activities, skills, and needed community services during weekly home visits.
Experimental: MET/CBT 7 without ACC
Behavioral: Motivational Enhancement Therapy/Cognitive Behavior Treatment (MET/CBT 7)
A manual-based 5-session MET/CBT model was supplemented with 2 family sessions. First was a family session to provide parents with an overview. Next was an individual adolescent MET session that focused on building rapport, explaining treatment, building motivation, and reviewing personalized feedback. In the third session, the therapist helped the adolescent complete a functional analysis of substance use and a personal goal worksheet. During sessions 4-6, the adolescent joined a closed group of 6 for 90-min CBT skills groups focusing on substance refusal skills, enhancing social support, planning for high-risk situations, and coping with relapse. The last session was a family session to review progress, relapse signs, and continuing care plans. Treatment lasted about 12 weeks.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Percentage of days abstinent from any alcohol and drugs
Time Frame: Baseline and 3, 6, 9, and 12 months post-baseline
Baseline and 3, 6, 9, and 12 months post-baseline
Change in Days abstinent from alcohol alone
Time Frame: Baseline and 3, 6, 9, and 12 months post-baseline
Baseline and 3, 6, 9, and 12 months post-baseline
Change in Substance use problems
Time Frame: Baseline and 3, 6, 9, and 12 months post-baseline
Measured using the Substance Problem Scale of the Global Appraisal of Individual Needs
Baseline and 3, 6, 9, and 12 months post-baseline
Change in Recovery status
Time Frame: 12 months post-baseline
Being in recovery at the end of the study was defined as living in the community (vs. being incarcerated, or residing in inpatient treatment or other controlled environment) and reporting no past month substance use, abuse, or dependence problems at the 12 month interview. Urine samples were collected as described above in Section 2.4.2, and when an adolescent reported being in recovery but the urine test result suggested a false-negative self-report, data were re-coded to show the adolescent as not being in recovery.
12 months post-baseline
