Attachment anxiety and smartphone addiction among university students during confinement: Teacher-student relationships, student-student relationships and school connectedness as mediators.

Learning at home during the COVID-19 confinement might affect students' relationships with their peers, teachers, and schools and increase the possibility of smartphone addiction. We hypothesized that attachment anxiety directly and indirectly affects smartphone addiction, with teacher-student relationships, student-student relationships, and school connectedness as mediators. The participants were 999 university students from different regions of China.
