Untreated chemical dependency costs the United States over $165 billion annually. Meanwhile, treatment offsets these costs by a ratio of $7 saved for every $1 spent. But the vast majority of chemically dependent people (CDPs) remain uninvolved in either treatment or self-help groups. It is therefore imperative that more effective ways be developed for therapeutically engaging them. One avenue is to maximize the opportunity presented when a "concerned other" (CO) person-such as a family member, friend, coworker, or clergy member-contacts a treatment agency to get help for a CDP. This paper provides a method for handling such calls. Specific guidelines are presented as to (a) the kind of information to b e gathered, (b) procedures to be followed, and (c) options to be offered toward mobilizing the CO and other family/social network members in successfully effecting CDP treatment engagement.
