Contingency management and motivational enhancement: a randomized clinical trial for college student smokers.

ABSTRACT:

Introduction

The efficacy of contingency-management (CM) and motivational enhancement therapy (MET) for college student smoking cessation was examined.

Methods

Nontreatment-seeking daily smokers (N = 110) were randomly assigned to 3 weeks of CM versus noncontingent reinforcement (NR) and to three individual sessions of MET versus a relaxation control in a 2 x 2 experimental design. Expired carbon monoxide (CO) samples were collected twice daily for 3 weeks. Participants earned 5 US dollars for providing each sample; additionally, those randomized to CM earned escalating monetary rewards based on CO reductions (Week 1) and smoking abstinence (Weeks 2-3).

Results

Compared with NR, CM resulted in significantly lower CO levels and greater total and consecutive abstinence
