Outcomes of the Smoker's Health Project: a pragmatic comparative effectiveness trial of tobacco-dependence interventions based on self-determination theory.

ABSTRACT: A pragmatic comparative effectiveness trial examined whether extending the duration of a cost-effective, intensive tobacco-dependence intervention designed to support autonomy will facilitate long-term tobacco abstinence. Participants were randomly assigned to one of three tobacco-dependence interventions based on self-determination theory, namely, Intensive Treatment (IT; six contacts over 6 months), Extended Need Support (ENS; eight contacts over 12 months) and Harm Reduction (HR; eight contacts over 12 months with medication use if willing to reduce cigarette use by half). Among participants who completed the interventions, analyses revealed beneficial effects of ENS (15.7 versus 3.8%; χ ²(1) = 6.92, P < 0.01) and HR (13.6 versus 3.8%; χ ²(1) = 5.26, P < 0.05), rel
