Smartphone-Delivered Attentional Bias Modification Training in Helping Patients Quit Smoking

PRIMARY OBJECTIVES: I. To determine the feasibility of smartphone-delivered, in-home attentional bias modification (ABM) to reduce attentional bias (AB) to smoking cues and to reduce smoking behavior in the short- and long-term. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive ABM training over 30 minutes through a smartphone on days 1-14. Patients then receive nicotine patches for up to 8 weeks. ARM II: Patients undergo sham training on days 1-14. Patients then receive nicotine patches for up to 8 weeks. After completion of study treatment, patients are followed up on days 15, 29, 43, 57, and 72.
