Abstract :This study evaluates the relationship between Internet addiction and academic performance among students of eight
Afghan universities. The differences between internet addiction in terms of gender was also identified. The
survey/research method adopted the Internet Addiction Test (IAT) based on Young’s survey applied with some
modifications. From 1000 distributed questionnaires only 976 participants (358 females, and 618 males) were
responded completely. The descriptive analysis was used to identify the demographic characteristics of student’s
Internet usage profile. The independents sample t-test was performed to determine the differences in the level of
Internet addiction in terms of gender. Statistical significance was set at a value of p <0.01. Likewise, the correlation
test was implemented to identify the relationship between Internet addiction and academic performance, with
referencing of sample. The results indicated that statistically there is a significant correlation among Internet addiction
and academic performance. Results also indicated that statistically there were significant differences between Internet
addictions in terms of demographic characteristics. This study suggests that future researchers need to work on large
sample while conducting the related research. It emphasizes that students should concentrate more on their academic
activities than spending time on unnecessary Internet surfing. Findings also revealed that, in Afghanistan the problem
of Internet addiction is not a serious challenge, but this information should be disseminated among undergraduate
university students to stop the indulgent in using the Internet.
