Summary

Contingency management (CM) is a type of treatment used in the substance abuse field. Patients' behaviors are rewarded for adherence to a treatment plan. As an approach to treatment, contingency management emerged from the behavior therapy traditions in mental health. By most evaluations, contingency management procedures produce one of the largest effect sizes out of all mental health and educational interventions. The purpose of this study is to perform a randomized, controlled trial to evaluate the ability of a culturally-tailored contingency management (CM) intervention to increase alcohol and drug abstinence among American Indian (AI) tribal members from two rural reservations in the Northwest.

Interventions

Type	Name	Description
BEHAVIORAL	CM for Alcohol	Escalating reinforcement for alcohol abstinence. Alcohol-negative CM Participants draw chips out of a bowl containing 500 chips. Fifty percent of the chips will say "good job!" or a similar encouraging phrase, 41.8% of the chips will result in a small prize, 8% will result in a large prize, and 0.2% will result in a jumbo prize.
BEHAVIORAL	CM for drugs	Escalating reinforcement for drug abstinence. Drug-negative participants will be invited to draw chips out of a bowl containing 500 chips. Fifty percent of the chips will say "good job!" or a similar encouraging phrase, 41.8% of the chips will result in a small prize, 8% will result in a large prize, and 0.2% will result in a jumbo prize.
BEHAVIORAL	CM for both substances	Escalating reinforcement for drug and alcohol abstinence. Drug- and alcohol-negative participants will be invited to draw chips out of a bowl containing 500 chips. Fifty percent of the chips will say "good job!" or a similar encouraging phrase, 41.8% of the chips will result in a small prize, 8% will result in a large prize, and 0.2% will result in a jumbo prize.
BEHAVIORAL	Non-Contingent group	Compensation for Non-Contingent control group participants is dependent only on providing urine samples, regardless of whether the urine tests are negative for alcohol and/or drugs.
