Outcome Measures
Primary Outcomes (7)
Cigarette Purchase Task- Omax
The Short-Cigarette Purchase Task (CPT) will be used to assess smoking reinforcement in response to stress-precipitated smoking. The CPT is based on progressive-ratio operant schedules wherein participants self-report their hypothetical cigarette consumption at various levels of price. Hypothetical purchasing will be based on the "last cigarette smoked". Five key behavioral economic indices of demand can be obtained from the CPT. One index reported here is the Omax, which is the number of cigarettes the individual endorses that they would purchase at the peak expenditure for a cigarette (i.e., highest endorsed US dollar per cigarette cost; Pmax).
Second Training Day following the Stress-Induction and Intervention (Smoking Task) i.e. post intervention, average 1 day.
Modified Cigarette Evaluation Questionnaire - Cigarette Satisfaction Subscale
The Modified Cigarette Evaluation Questionnaire (mCEQ) will be used to assess subjective smoking reinforcement. The mCEQ is a self-report measure that assesses how respondents feel about the "last cigarette smoked" with three subscales. One subscale indexes liking, or cigarette satisfaction. Score on this subscale range from 1 to 7, with higher scores reflecting greater subjective smoking satisfaction. Scores on the mCEQ cigarette satisfaction subscale administered post stress-precipitated smoking, during Visit 2, will be compared between conditions.
Second Training Day following the Stress-Induction and Intervention (Smoking Task) i.e. post intervention, average 1 days.
Cigarette Purchase Task - Intensity
The Short-Cigarette Purchase Task (CPT) will be used to assess smoking reinforcement in response to stress-precipitated smoking. The CPT is based on progressive-ratio operant schedules wherein participants self-report their hypothetical cigarette consumption at various levels of price. Hypothetical purchasing will be based on the "last cigarette smoked". Five key behavioral economic indices of demand can be obtained from the CPT. One index reported here is intensity, which is the number of cigarettes consumed at zero cost.
Second Training Day following the Stress-Induction and Intervention (Smoking Task) i.e. post intervention, average 1 day.
Cigarette Purchase Task- Pmax
The Short-Cigarette Purchase Task (CPT) will be used to assess smoking reinforcement in response to stress-precipitated smoking. The CPT is based on progressive-ratio operant schedules wherein participants self-report their hypothetical cigarette consumption at various levels of price. Hypothetical purchasing will be based on the "last cigarette smoked". Five key behavioral economic indices of demand can be obtained from the CPT. One index reported here is the Pmax, which is the price at maximum expenditure for a cigarette.
Second Training Day following the Stress-Induction and Intervention (Smoking Task) i.e. post intervention, average 1 day.
Cigarette Purchase Task- Breakpoint
The Short-Cigarette Purchase Task (CPT) will be used to assess smoking reinforcement in response to stress-precipitated smoking. The CPT is based on progressive-ratio operant schedules wherein participants self-report their hypothetical cigarette consumption at various levels of price. Hypothetical purchasing will be based on the "last cigarette smoked". Five key behavioral economic indices of demand can be obtained from the CPT. One index reported here is the breakpoint, which is the cost whereby consumption is suppressed to zero.
Second Training Day following the Stress-Induction and Intervention (Smoking Task) i.e. post intervention, average 1 day.
Modified Cigarette Evaluation Questionnaire - Craving Reduction Subscale
The Modified Cigarette Evaluation Questionnaire (mCEQ) will be used to assess subjective smoking reinforcement. The mCEQ is a self-report measure that assesses how respondents feel about the "last cigarette smoked" with three subscales. One subscale indexes wanting, or cigarette craving reduction. Score on this subscale range from 1 to 7, with higher scores reflecting greater subjective cigarette craving reduction. Scores on the mCEQ craving reduction subscale administered post stress-precipitated smoking, during Visit 2, will be compared between conditions.
Second Training Day following the Stress-Induction and Intervention (Smoking Task) i.e. post intervention, average 1 days.
Modified Cigarette Evaluation Questionnaire - Psychological Reward Subscale
The Modified Cigarette Evaluation Questionnaire (mCEQ) will be used to assess subjective smoking reinforcement. The mCEQ is a self-report measure that assesses how respondents feel about the "last cigarette smoked" with three subscales. One subscale indexes learning, or psychological reward. Score on this subscale range from 1 to 7, with higher scores reflecting greater subjective psychological reward. Scores on the mCEQ psychological reward subscale administered post stress-precipitated smoking, during Visit 2, will be compared between conditions.
Second Training Day following the Stress-Induction and Intervention (Smoking Task) i.e. post intervention, average 1 days.
Secondary Outcomes (2)
Changes in Cardiac Vagal Control
Second Training Day prior to Stress-Induction, and following Stress-Induction during Intervention (Smoking Task), average 1 day.
Puff Topography
Second Training Day following Stress-Induction during Intervention (Smoking Task), average 1 day.
Study Arms (2)
Control
SHAM COMPARATORIn this condition, participants are instructed to smoke as usual while attending to control stimuli presented to them on a computer monitor.
Puff Topography Biofeedback Training (PTBT)
EXPERIMENTALIn this condition, participants are provided instructions on how to puff their cigarette via a computer-assisted paradigm.
Interventions
Visit 1: Participants will be asked to smoke their usual brand cigarette using the CReSS smoking topography device. Participants will be instructed on how to follow visual and auditory puffing prompts provided to them by a computer program in order to control puffing behavior for a duration of five minutes. Visit 2: Participants will be instructed to smoke their cigarette using the CReSS device and instructions provided during Visit 1 after undergoing a brief laboratory stress induction.
Visit 1: Participants will be instructed to smoke their usual brand cigarette using the CReSS smoking topography device while passively viewing time-matched control stimulus presented to them on a computer monitor for a duration of five minutes. Visit 2: Participants will be instructed to smoke their cigarette using the CReSS device and instructions provided during Visit 1 after undergoing a brief laboratory stress induction.
Eligibility Criteria
You may qualify if:
- Age 18-55
- Daily smoking ≥ 8 cigarettes/day verified by carbon monoxide analysis of breath sample ≥ 8 ppm
