**5. Conclusions**

In sum, this pilot study used solution-focused group counseling to treat college students with moderate to high levels of IA symptoms. The results suggested that solution-focused group counseling had positive effects on IA and some of its core dimensions, and was generally positively valued by participants. SFBT has the characteristics of high-efficiency, simplicity and durability in intervening with college students' Internet use. We call for further studies to apply this approach and examine its merits.
