“…We identified the Theory of Planned Behaviour (TPB) with modification as the foundation of our study. TPB has been widely used in various studies and had proven its versatility in its application, such as in intention to quit smoking or alcohol (Paswan, Gai, & Sua, 2015;Soulakova, Li & Crokett, 2017), on online purchase intention (Lim, Yap & Lee, 2011); on crisis planning intention (Wang & Ritchie, 2012) or on fertility intention (Dommermuth, Klobas & Lappegard, 2011).
