Objective: We aimed to explore the effect of loneliness on phubbing and the mediating
role of social self-efficacy. Methods: Taking 902 individuals as subjects, they completed the loneliness
scale(UCLA), the phubbing scale(GSP) and the social self-efficacy scale(PSSE). Results: ① The proportion
of individual with high total score of phubbing accounted for 41.1%. The scores of interpersonal conflict
dimension and self-isolation dimension were significantly higher in men than in women, and the scores
of only child were significantly higher than those of only-one children. In terms of age, the phubbing of
18~25 years old and 51~60 years old was significantly higher than that of other age stages. ② Loneliness
was positively correlated with phubbing(r=0.38; p<0.01), social self-efficacy was negatively correlated
with loneliness and phubbing(r=-0.51~-0.12; p<0.01). ③ Loneliness positively predicts phubbing (β=0.38;
p<0.001). Social self-efficacy played a partial mediating role in the relationship between loneliness and
phubbing, The mediating effect accounts for 16.10%. Conclusion: Loneliness not only directly affected
the individual phubbing, but also indirectly affects the phubbing by reducing social self-efficacy.
