Differentiating the Determinants of Ever Having Used a Vape Versus Use Frequency: A Hurdle Modelling Approach

Findings indicate that both ever-use of a vape and frequency of use are associated with beliefs of the outcomes and experiential experiences of the behaviour, rather than by cognitive evaluations of harm. Although conclusions are limited by the cross-sectional design, current results point to the possibility that the psychological determinants of initial experimentation with vaping may differ from those that sustain use frequency.
