Moderators of delay tolerance in treatment-seeking cocaine users.

A substantial amount of attrition in cocaine dependence treatment studies occurs between the initial telephone contact and the first evaluative clinic visit. While decreasing the wait to first visit can significantly reduce pre-intake attrition (PIA), little is known about other factors that moderate delay tolerance for first clinic visit. The current report uses data from 833 subjects who completed a first-contact telephone interview prior to an intake evaluation visit for cocaine use treatment research.
