The purpose of this paper is to develop an Internet Anxiety Scale (IASv1) by referring to the research of Presno and the computer anxiety scale, and to examine the differences between Internet anxiety and computer anxiety. IASv1 consists of the following four factors: “Internet reliability anxiety,” “Internet knowledge anxiety,” “Avoiding the Internet,” and “Internet search anxiety.” As for the relationship between IASv1 and the computer anxiety scale (ACAS), it can be said that IASv1 is roughly similar to ACAS. However, only “Internet reliability anxiety” was different from other factors, suggesting that the IASv1 is a necessary scale for early identification and intervention for students with Internet anxiety.
