For Researchers
- Baseline Assessment (with demographic characteristics, tobacco use, waterpipe smoking, and waterpipe smoking dependence)
- Individual Ratings of Warning Messages (Rating Questionnaire)
- 3 Month follow up (assessing harm perception, intention to quit smoking, recall, change in waterpipe smoking)
- Harm perception will be asked pre-/post-smoking and at 3-month assessment using 1 item “To what extent are you thinking about the serious health effects of WP smoking?” (Thrasher 2012).
- Intention and motivation to quit will be asked pre-/post-smoking and at 3-month assessment using 3 items; “Do you intend to reduce WP smoking?”; “Do you intend to quit WP smoking?”, and “How motivated are you to quit WP smoking in the next month?” (Carpenter 2004).
- Recall will be asked at 3-month assessment using 1 item “Try to recall what the HWLs warning information were stated and type it in the box below” (Kees 2010).
- Social interaction will be asked at 3-month assessment using 1 item “Since you started the study, how many times did you have a conversations with your family/friends about the HWLs?” (Brewer 2016).
- Change in WP smoking will be asked at 3-month assessment using 3 items; “Since you started the study, 1- did you stop smoking for 1 day or longer because you were trying to quit WP smoking?, 2- did you avoid smoking WP because you were thinking about the HWLs?, and 3- did you stop WP smoking completely because of the HWLs?” (Brewer 2016).
- Subjective dependence and satisfaction measures assess smoker’s satisfaction with smoking, and the direct effects of tobacco/nicotine consumption on dependence measures (e.g. withdrawal and craving). We will use 4 subjective measures:
- The Duke Sensory Questionnaire (DSQ) (Malson 2002, Pickworth 2002)
- The Cigarette/WP Evaluation Scale (WES) (Rose 2000, Malson 2002)
- The brief version of Questionnaire of Smoking Urges-brief (QSU) (Cox 2001)
- Minnesota Nicotine Withdrawal Scale (MNWS) (Hughes 1986).
- Use satisfaction (Modified Cigarette Evaluation Questionnaire-mCEQ)
- Dependence (Questionnaire of Smoking Urges-brief; Minnesota Nicotine Withdrawal Scale; Penn State Electronic Cigarette Dependence Index)
- Puff sensory effects (Duke Sensory Scale) (Maziak et al., 2019a; Foulds et al., 2015; Malson & Pickworth, 2002).
