The term “phubbing” describes individuals’ engagement with their smartphones during face-to-face conversations. Because some scholars treated phubbing as a trait experience, the predictors they investigated to explain this behavior have also been trait predictors. This paper reports on a study that used the state phubbing scale, which took into account both the fleeting and the psychological properties of this behavior, and applied a set of state predictors that perceived phubbing as a state experience (state boredom, state of fear of missing out and state loneliness). Data was collected using an online survey. The results from the multiple regression analysis revealed that the state of fear of missing out was a stronger predictor of state phubbing with state boredom also predicting state phubbing to a lesser extent. State loneliness didn’t predict this behaviour. Understanding the immediate predictors of phubbing is important, considering the negative effects of this behavior on offline relationships.
