Smartphone-Delivered Attentional Bias Modification Training in Helping Patients Quit Smoking
Smartphone-Delivered Attentional Bias Modification Training for Quitting Smokers
Study Overview
Status
Conditions
Detailed Description
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.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Modified Dot-probe Task
Time Frame: Up to 8 weeks post-training
|
Modified dot-probe task evaluated by using 2 (group: ABM vs. sham) X 3 (session: baseline, 1-day post-training, and 8-weeks post-training) linear mixed model using RT difference scores (neutral-cigarette) as the dependent measures and subject as the random effect.
|
Up to 8 weeks post-training
|
|
Smoking Stroop Task
Time Frame: Up to 8 weeks post-training
|
The Stroop task will consist of three blocks, with a 5-s rest period between blocks: (a) practice (40 trials), (b) neutral words (80 trials), and (c) smoking words (80 trials).
The score will be calculated by taking the mean RT difference between the smoking and neutral words on trials with correct responses within the response window.
|
Up to 8 weeks post-training
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Cigarette Per Day (CPD)
Time Frame: Up to 8 weeks post-training
|
Mean number of cigarettes per day smoked for the seven days preceding each time point.
|
Up to 8 weeks post-training
|
|
Expired Carbon Monoxide (CO)
Time Frame: Up to 8 weeks post-training
|
Mean expired carbon monoxide, in ppm (parts per million), at each time point.
|
Up to 8 weeks post-training
|
|
Urinary Cotinine
Time Frame: Up to 8 weeks post-training
|
Mean urinary cotinine, measured in ng/mL, at each time point.
|
Up to 8 weeks post-training
|
|
Fagerström Test for Nicotine Dependence (FTND)
Time Frame: Up to 8 weeks post-training
|
The Fagerström Test for Nicotine Dependence, yes/no items are scored from 0 to 1 and multiple-choice items are scored from 0 to 3. The items are summed to yield a total score of 0-10.
The higher the total Fagerström score, the more intense is the patient's physical dependence on nicotine.
Mean Fagerström Test for Nicotine Dependence (FTND) questionnaire score at each time point.
|
Up to 8 weeks post-training
|
|
Wisconsin Smoking Withdrawal Scale (WSWS) - Craving
Time Frame: Up to 8 weeks post-training
|
Mean Wisconsin Smoking Withdrawal Scale (WSWS) - Craving subscale score at each time point.
Participants rate each item on a scale of 0-4 (0=Strongly disagree, 1=Disagree, 2=Feel neutral, 3=Agree, 4=Strongly agree).
The subscale to each item is determined on how high they agree on the scale.
Mean Wisconsin Smoking Withdrawal Scale (WSWS) - Craving subscale score at each time point.
For some items, the subscale is determined on how low they agreed.
Each score is determined by the mean of each item that applies.
Higher means indicate greater withdrawal.

Up to 8 weeks post-training
