This randomized clinical trial will test the efficacy of a Facebook intervention based on the Transtheoretical Model (Prochaska and DiClemente) and US Public Health Service Clinical Practice Guidelines with young adults who smoke cigarettes who are age 18 to 25 (N=480).
Participants will be randomized to one of two conditions: (1) a Facebook-delivered intervention tailored to readiness to quit smoking; or (2) the control condition (referral to the Smokefree.gov website). The intervention will include 12 weeks of Facebook-based messages and activities tailored to participants' stage of change. Assessments will occur at baseline, 3, 6, and 12 months follow-up. Assessments will include measures on smoking patterns and thoughts about abstinence. All participants who report no past 7-day smoking will be asked to give biochemical verification of smoking status with saliva cotinine test kits that will be mailed to participants.
