Objective: This project examined the effectiveness of tailored text messages as an enhancement to a computerized tailored intervention (CTI) for smoking cessation with Veterans. It was theorized that the ubiquity and sophistication of today's wireless mobile technologies would represent new modes of delivery for empirically based smoking cessation and other behavioral health interventions. CTIs have shown increasing promise as useful behavior change programs for improved health behaviors; however, the ubiquity and sophistication of today's wireless mobile technologies represent new modes of delivery for evidence-based smoking cessation and other behavioral health interventions. The CTI was based on the Transtheoretical Model of Behavior Change (TTM) and developed by Pro-Change Behavior Systems, Inc.
