A method, the Albany-Rochester Interventional Sequence for Engagement (ARISE), is described for engaging highly ambivalent alcohol- and/or drug-dependent individuals in treatment. A three stage interventional sequence is presented, which begins when a family member or concerned other contacts a treatment program regarding a substance abuser who needs help. At that point a process is set in motion for collaboration with significant others toward client enrollment. Staff move to the next stage in a graduated operating procedure if initial, less demanding efforts do not succeed. The final stage, if needed, is a modified Johnson Institute Intervention. The overall procedure is designed to maximize the probability of patient recruitment, while minimizing the amount of time and energy required of staff. The method compares favorably with results obtained with other approaches, such as coercion (legal, employer) and client self-referral.
