Internet addiction (IA) is a relatively new subject of study in academia, and it has several effects on
a person's life in a variety of ways, including academic achievement, relationships, physical and
mental health. Aim: To describe the effect of internet addiction on academic achievement among
primary school children. Research Design: A descriptive research design was used in the current
study. Settings: The study was applied in two primary schools in PortSaid City. The Study
Sample: A multi-stage random sample of 720 primary school children was recruited using a multi
stage random sample technique. Tools: There were three tools used in the current study as the
following: socio-demographic assessment tool, Young's internet addiction scale, and academic
achievement assessment tool. Results: more than half of the primary school children were female;
the mean age of them was 9.34 ± 1.64 years. Half of them spent 3-5 daily times on the internet.
There was an association between internet addiction and academic achievement. The majority of
primary school children agree to improve the awareness about internet addiction and its effects
through holding classes as proposed preventive interventions to reduce harm from IA. Conclusion:
Excessive internet usage was shown to be one of the most common behaviors among primary
school children, which can lead to addiction and harm their personal, social, and academic
achievement. Recommendation: Children should be aware of the potentially detrimental effects of
internet addiction, as well as the necessity to restrict internet usage, which can have a severe impact
on kids' academic progress.
