Proposed diagnostic criteria and the screening and diagnosing tool of Internet addiction in college students.
The aims of this study were to develop diagnostic criteria of Internet addiction for college students (DC-IA-C) with diagnostic interviews and to establish the optimal cutoff points of the Chen Internet Addiction Scale (CIAS) for the purposes of screening for and making the diagnosis of Internet addiction. A total of 216 college students (132 male and 84 female) were recruited in the study. The results demonstrated that 5/6 cutoff points of criteria A in DC-IA-C had the best diagnostic accuracy (95.9%). Besides, 63/64 and 67/68 cutoff points of the CIAS were evaluated to be the best screening and diagnostic cutoff points, respectively. The DC-IA-C can provide health care professionals with a means to diagnose and communicate about Internet addiction among college students, and the screening and diagnostic cutoff points of CIAS could provide a screening instrument or a discriminative instrument in surveys for Internet addiction among college students.
