Dynamic Assessment and Referral System - Evaluation

The investigators study will use a randomized controlled design. Eligible and consenting participants will be randomly assigned to one of two conditions: (1) DARSSA Intervention condition, or (2) Minimal Intervention Control condition. All enrolled participants will undergo the DARSSA baseline assessment and will be interviewed immediately following their ED discharge to assess relevant outcomes, such as whether they were asked about substance use and given a referral during their visit. This is referred to as the post-visit interview. All risky substance users enrolled during all phases will be interviewed again at 1- and 3-months post-visit to assess substance use, treatment engagement, and other outcomes. The primary difference between the two conditions is that, for the DARSSA Intervention condition, the subjects will have their reports printed and will be given the option of receiving the dynamic referral, while for the Minimal Intervention Control condition the subjects will undergo the assessment and will receive the standard substance abuse treatment referral list currently in use clinically at each site. The number of assessments and interactions with research staff will remain equal between the two conditions, with the only difference being the active intervention of the DARSSA reports and referrals, and any counseling by healthcare providers this engenders. The remainder of this section describes each phase of the study and enrollment procedures.
