A randomized trial of an avatar-hosted multiple behavior change intervention for young adult smokers.

Background: Young adulthood is a critical transition period for the development of health behaviors. We present here the results of a randomized controlled trial of an online avatar-hosted personal health makeover program designed for young adult smokers.

Methods: We conducted a three-group randomized trial comparing delivery of general lifestyle content (Tx1), personally tailored health information (Tx2), and personally tailored health information plus online video-based peer coaching (Tx3) as part of a 6-week online health program.
