Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
OBJECTIVES AND HYPOTHESES: The objective of this study was to evaluate the relative effectiveness of quarterly checkups on long-term outcomes of adult chronic substance users over 4 years. Relative to participants randomly assigned to the control group, we predicted that RMC participants would: H1) return to treatment sooner, H2) receive more treatment, H3) decrease substance use, and H4) increase days of abstinence.
METHOD: Participants were recruited from sequential intakes at the largest addiction treatment agency in Illinois between February and April of 2004. Inclusion criteria were: any substance use in the past 90 days and any past-year symptoms of substance use disorders. For logistical reasons, participants were excluded if they were: under 18, lived or planned to move outside Chicago within 12 months, sentenced to a confined environment most of the next 12 months, mandated to treatment because of a driving under the influence offense, were not fluent in English or Spanish, or were cognitively unable to provide informed consent. To evaluate efficacy of quarterly Recovery Management Checkups (RMC) on treatment reentry and substance use, 446 adults (88% with dependence criteria) were randomly assigned quarterly RMCs, or, an outcome monitoring only control group and followed quarterly for 4 years (94% completion).
INTERVENTION. After interviewers completed the quarterly research interview and determined participants' eligibility and need for early re-intervention, they transferred RMC participants who were eligible and in need to a Linkage Manager. Using motivational interviewing, the Linkage Manager: a) provided feedback to participants regarding their current substance use and related problems, b) discussed implications of managing addiction as a chronic condition, c) discussed treatment barriers and solutions, d) assessed and discussed level of motivation for treatment, e) scheduled treatment appointments, f) accompanied participants to treatment intake and stayed through the process, and g) implemented Engagement and Retention Protocol during the 14 days of treatment. Detailed procedures and forms are available in the RMC manual(Scott \& Dennis, 2003; http://www.chestnut.org/LI/downloads/Scott\_\&\_Dennis\_2003\_RMC\_Manual-2\_25\_03.pdf ).
OUTCOME MEASURES: Days to first treatment, days of treatment, successive quarters of needing treatment, number of substance problem months, days of abstinence.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Recovery Management Checkups (RMC)
Participants in the RMC group are interviewed quarterly. When they were found to be in need of treatment, the participant was transferred from the interviewer to a linkage manager to receive the intervention (described next). They were also able to re-enter treatment on their own and naturally cycle through multiple periods of substance use, treatment, incarceration and recovery.

Control Group
Participants in the control group are interviewed quarterly. While they do not receive any active intervention from the research team, they are able to re-enter treatment on their own and naturally cycle through multiple periods of substance use, treatment, incarceration and recovery.
