A Mediation Analysis of Motivational, Reduction, and Usual Care Interventions for Smokers Who Are Not Ready to Quit.

ABSTRACT:

Introduction

We recently conducted a large randomized controlled trial (RCT) (N = 560) that failed to replicate our initial RCT's findings that brief motivational and reduction interventions increased quit attempts (QA) and point-prevalence abstinence (PPA) in smokers not ready to quit.
