Outcome Measures
Primary Outcome Measures
- Number of Participants Who Self-Reported Abstinence and Who Were Biochemically Verified as Abstinent Via Expired CO Level of ≤ 5ppm [6 weeks]
- Post-quit Craving as Assessed by the Questionnaire of Smoking Urges [6 weeks]
Questionnaire of Smoking Urges (QSU) is a 10-item scale (total score range = 10-70, a lower score indicates lower cravings for cigarettes) that evaluates the intention and desire to smoke and anticipation of relief from withdrawal-associated negative affect.
- Withdrawal Symptoms as Assessed by the Wisconsin Smoking Withdrawal Scale [6 weeks]
The Wisconsin Smoking Withdrawal Scale is a 28-item questionnaire designed to assess different aspects of the smoking withdrawal syndrome. Participants rate each item on a Likert scale from zero (strongly disagree) to four (strongly agree). Total score ranges from 0 to 112, with a higher score indicating greater withdrawal.
- Cue-induced Craving for Cigarettes Following Virtual Reality Exposure as Assessed by the Questionnaire of Smoking Urges [1 week]
Questionnaire of Smoking Urges (QSU) is a 10-item scale (total score range = 10-70, a lower score indicates lower cravings for cigarettes) that evaluates the intention and desire to smoke and anticipation of relief from withdrawal-associated negative affect.
- Cue-induced Craving for Cigarettes Following Virtual Reality Exposure as Assessed by the Questionnaire of Smoking Urges [3 weeks]
Questionnaire of Smoking Urges (QSU) is a 10-item scale (total score range = 10-70, a lower score indicates lower cravings for cigarettes) that evaluates the intention and desire to smoke and anticipation of relief from withdrawal-associated negative affect.
Secondary Outcome Measures
- Number of Participants Who Self-Reported Abstinence and Who Were Biochemically Verified as Abstinent Via Expired CO Level of ≤ 5ppm [7 weeks (1 week after end of treatment)]
- Number of Participants Who Self-Reported Abstinence and Who Were Biochemically Verified as Abstinent Via Expired CO Level of ≤ 5ppm [10 weeks (4 weeks after end of treatment)]
- Post-quit Craving as Assessed by the Questionnaire of Smoking Urges [7 weeks (1 week after end of treatment)]
Questionnaire of Smoking Urges (QSU) is a 10-item scale (total score range = 10-70, a lower score indicates lower cravings for cigarettes) that evaluates the intention and desire to smoke and anticipation of relief from withdrawal-associated negative affect.
- Post-quit Craving as Assessed by the Questionnaire of Smoking Urges [10 weeks (4 weeks after end of treatment)]
Questionnaire of Smoking Urges (QSU) is a 10-item scale (total score range = 10-70, a lower score indicates lower cravings for cigarettes) that evaluates the intention and desire to smoke and anticipation of relief from withdrawal-associated negative affect.
