Objective To explore the relationship between impulsiveness and risky decision-making among college students with pathological internet use ( PIU),as well as the moderating role of self-control. Methods Totally 542 undergraduates anonymously completed the Internet Addiction Test (IAT),Chinese Version of Barratt Impulsiveness Scale,Risk Preference Questionnaire,Self-Control Scale. Results ( 1) In loss frames,the scores of risky decision-making with high (20. 26±4. 83) and medium (20. 40±5. 53) level of impulsiveness among college students with PIU significantly were higher than those with low ( 18. 92 ± 5. 03) level of impulsiveness ( F(2,323)= 3. 79,P<0. 05,η2=0. 02). (2) There was a significant negative correlation between impulsiveness (60. 68±10. 40) and self-control (55. 56±9. 07) (r=-0. 60,P<0. 01). And there was a significant positive correlations between impulsiveness and risky decision-making in loss frames (20. 12±5. 26)(r=0. 13,P<0. 05). The risky decision-making in gain frames ( 17. 17±4. 38) was positively correlated with that in loss frames (r=0. 52,P<0. 01). (3) Self-control played a moderating role in the association between impulsiveness and risky decision-making in loss frames (β=0. 13,t=2. 31,P<0. 05). Conclusion In loss frames,impulsiveness is positively related with risky decision-making,and self-control plays a moderating role between impulsiveness and risky decision-making in loss frames among col-lege students with PIU.

(2)There was a significant negative correlation between impulsiveness (60.68±10.40) and self-control (55.56±9.07)(r=-0.60, P<0.01). And there was a significant positive correlations between impulsiveness and risky decision-making in loss frames (20.12±5.26)(r=0.13, P<0.05). The risky decision-making in gain frames (17.17±4.38) was positively correlated with that in loss frames (r=0.52, P<0.01). (3)Self-control played a moderating role in the association between impulsiveness and risky decision-making in loss frames (β=0.13, t=2.31, P<0.05). Conclusion In loss frames, impulsiveness is positively related with risky decision-making, and self-control plays a moderating role between impulsiveness and risky decision-making in loss frames among college students with PIU.
