The present project will evaluate the initial efficacy of approach bias retraining among dual combustible cigarette (CC) and electronic cigarette (ECIG) users. The study employs a randomized controlled design to follow 90 experienced dual CC/ECIG users motivated to quit nicotine as they engage in a self-guided quit attempt following approach bias retraining.
The study employs a randomized controlled design to follow 90 experienced dual CC/ECIG users motivated to quit nicotine as they engage in a self-guided quit attempt following approach bias retraining. Participants will be randomized to one of three approach bias retraining conditions: (1) CC+ECIG; (2) CC only; or (3) sham (control). Participants will complete a phone pre-screener, baseline (week 1 of study participation), 4 approach bias retraining sessions in laboratory (with quit day scheduled for the 4th session; weeks 2-5 of study participation), and follow-up assessments at 4- and 6-weeks post-intervention (i.e., weeks 9 and 11 of study participation, respectfully). Participants also will complete ecological momentary assessments (EMA) of CC smoking, ECIG use, and CC and ECIG urges/cravings for 14 days post-intervention (i.e., weeks 5-7 of study participation) on Internet capable smartphones. The only time data will be collected is when participants complete EMA assessments or follow up surveys using the REDCap app on the smartphone.

Smoking on fewer than 7 consecutive days or smoking fewer than once each week over 2 consecutive weeks (CC and/or ECIG)
Time frame: Week 9 of participation

Questionnaire of Smoking Urges-Brief (QSU-Brief)
The Brief Questionnaire of Smoking Urges (QSU-Brief) consists of 10 statements about the respondent's feelings and thoughts about his or her desire to smoke cigarettes as he or she is completing the questionnaire (i.e., right now).
Time frame: Week 1-7, 9, and 11 of participation
Questionnaire of Vaping Craving
The Questionnaire of Vaping Craving is a modified measure of the QSU and consists of 10 statements about the respondent's feelings and thoughts about his or her desire to vape as he or she is completing the questionnaire (i.e., right now).
Time frame: Week 1-7, 9, and 11 of participation
Approach Bias
The approach-avoidance task (AAT) is a 15-minute computerized task instructs participants to use a joystick to either pull toward themselves or push away from themselves images presented on the screen that vary in content (i.e., substance-related, neutral, positive) and format (e.g., right- or left-tilted).
