Current study
PMT
The purpose of the proposed study is to examine the effectiveness of an intervention grounded in the threat appraisal components of a PMT framework (i.e., PV and PS) that seeks to mitigate vaping intention and behaviour among Canadian university students that identify as regular vapers, vaping at least three times over 30 days prior to enrolling in the study (Hence, our research question was as follows: “Is health threatening information effective in motivating Canadian university students who regularly vape to reduce their intentions to vape and overall vaping behaviour?” Within this general research question, the following specific hypotheses were generated: (a) those exposed to the threat appraisal information grounded in the PMT components of severity and vulnerability will score higher on purpose-built questions reflecting these components than their attentional information control (nutrition and lifestyle information) counterparts; (b) those exposed to the threat appraisal information grounded in the PMT components of severity and vulnerability will show lower intentions to vape and lower vaping use compared to their attentional information control counterpart; and (c) increases both severity and vulnerability of vaping usage will be associated with a reduction in intentions to vape. Furthermore, reduction in intentions to vaping will be associated with lower vaping use.
