ISAP Research Projects
Name of Project: Contingency Management Schedules
for Initiating Abstinence
Principal Investigator: John M. Roll, Ph. D.
Co-Principal Investigators: Steven Shoptaw, Ph.D. and Alice Huber, Ph. D.
Project Director: Joy Chudzynski, M.A.
Funding Agency: National Institute on Drug Abuse
(NIDA)
Funding Period: September 1999-August 2004
Scope of Project: This study is designed to elucidate
the appropriate contingency management intervention for initiating
abstinence during the course of clinical trials investigating
potential pharmacotherapies for stimulant abuse. Abstinence can
be conceived of as having two discrete components, initiation
and maintenance, and this study has been designed to specifically
isolate the factors that are necessary in a contingency management
intervention to initiate abstinence. Participants will be randomly
assigned to receive one of twelve different contingency management
schedules, each of which lasts for 12 weeks. All contingency management
vouchers will be contingent upon urine samples that test negative
for methamphetamine and cocaine. In addition, each participant
will attend relapse prevention groups for 16 weeks. The proposed
design allows for evaluation of the efficacy of these contingency
management schedules in initiating abstinence, reducing drug use,
enhancing psychosocial functioning, and in mitigating HIV-related
risk behaviors.
