INTRODUCTION Based on the theoretical frameworks of the Theory of Triadic Influence (TTI), this longitudinal study was designed to examine the mediating role of avoidance/emotion-focused coping in the relationship between distress tolerance and problematic Internet use (PIU) in a large representative sample of senior high school students in Taiwan. METHODS Through a 1-year follow-up design, 2170 participants were recruited from high schools throughout Taiwan using both stratified and cluster sampling in time 1 (T1), and 1832 students were followed-up 1 year later (T2). RESULTS Structure equation modeling and bootstrap analyses results showed that after controlling for PIU measured at T1, PIU (T2) was significantly predicted by distress tolerance (T1) and fully mediated through avoidance/emotion-focused coping (T2). CONCLUSIONS The results not only support the TTI framework, but can also serve as a reference to help educational agencies and mental health organizations create policies and design programs that will help in the prevention of PIU among adolescents. The mediating role of avoidance/emotion-focused coping in the relationship between distress tolerance and PIU was discussed.
