Client participants of counselors who were randomized to the experimental condition will receive the following intervention: The online Navigating my Journey relapse prevention program is an adjunct to outpatient treatment. We will ask client participants to complete at least 12 Navigating my Journey sessions and discuss them with their counselors.

Client participants of counselors who were randomized to the control condition will receive their typical course of counseling and a link to online online health information in PDF form as an attention control.

The online relapse prevention program called Navigating my Journey is designed for adolescents who are receiving outpatient treatment for substance abuse. Since the Navigating my Journey program will be available to adolescents 24/7, it is easy for them to access at their convenience. The program functions as an adjunct to treatment and is designed to complement and enhance the work the adolescent does with the counselor during counseling sessions. The core intervention is expected to last for 12 weeks.

Participants will be asked how many days in the past 30 days they used a variety of substances, including alcohol. This self report question format is widely used to assess substance use (e.g., the GPRA from CSAT; SAMHSA, 2010).

The 32-item University of Rhode Island Change Assessment Questionnaire (URICA; McConnaughy et al., 1983, 1989) will be used to measure motivation to change. It has four 8-item scales (Precontemplation, Contemplation, Action, and Maintenance) that can be combined to create a single Readiness to Change score (C + A + M - PC = Readiness). Participants rate each item 1=Strongly Disagree to 5=Strongly Agree. This scale has good reliability and validity with adolescents (Greenstein et al., 1999).

Drug Avoidance Self-Efficacy Scale (DASES). The DASES (Martin et al., 1995) assesses one's current self-efficacy to resist drug use in hypothetical high-risk situations. The scale contains 16 items, and responses are rated on a 7-point scale ranging from "certainly yes" to "certainly no."

The ARCQ (Myers et al., 2006) assesses "temptation coping responses among adolescents." It begins with a short assessment of appraisal (5 items total) of a situation where peers are drinking and using, followed by 28 items rated between 1 = Definitely would not do or think, through 7 = Definitely would do or think. These 28 items comprise three subscales: Cognitive and behavioral problem solving (e.g., Let your feelings out somehow; alpha = .82); Self-critical thinking (e.g., Criticize or lecture yourself; alpha = .80); and Abstinence-focused coping (e.g., Leave or avoid the situation; alpha = .78).

Working Alliance Inventory-Short Form (Clients) (WAI-S). The working alliance between counselor and client is a critical indicator of client outcomes. The WAI-S (Tracey & Kokotovic, 1989) is a short form (12 items) of the original WAI (36 items). It has three sub-scales - therapeutic bond, agreement on tasks, and agreement about goals. Items are scored on a 7-point scale (1 = rarely to 7 = always, range 12-84).
