Background and aims: Stress is a common experience among college students with problematic Internet use, and it may exacerbate their cue-induced Internet craving. This study aimed to examine the influence of stress on cue-induced craving for the Internet among subjects with problematic Internet use and the buffering effect of mindfulness. Methods: Sixty-eight college students with problematic Internet use were assigned to groups with a 2 (stress vs. no-stress)32 (high vs. low mindfulness) betweensubject design. Results: It was deduced that stress could significantly enhance cue-induced craving for the Internet, and mindfulness could buffer this effect. Specifically, the effect of stress on cue-induced craving for the Internet was weaker among subjects with high mindfulness as compared to subjects with low mindfulness. Discussion and Conclusions: These findings contribute to understanding of the factors influencing problematic Internet use and how such factors interact. It also provides recommendations on how to prevent the progression of problematic Internet use and suggests possible interventions.  Kulcsszavak: cue-induced craving, stress, mindfulness, problematic internet use
