Prevalence of Internet Addiction and Its Association with Psychological Disorders Among Medical Students in Saudi Arabia.

Background: Internet addiction is increasing worldwide. Internet addiction (IA) refers to excessive Internet usage in an uncontrolled and time-consuming manner, causing loss of time and disruption of daily life. However, the prevalence of IA may vary according to age, sex, and ethnicity, and is more prevalent among college students. There is a strong link between problematic Internet usage and an increased risk of developing Post Traumatic Stress Disorder PTSD and depression symptoms. Medical students were chosen for this study due to their unique stressors, including rigorous academic demands, extensive study hours, and clinical practice requirements. It is critical to address behavioral addictions and their psychological effects in this group, as they are linked to the future quality of healthcare provision compared with their non-medical peers.

Objective: To estimate the prevalence of Problematic Internet Use (PIU) in medical students and explore their correlation with the medical students' PTSD and Patient Health Questionnaire -9 (PHQ9) scores.

Methods: A cross-sectional online survey was conducted including 506 medical students in the second year of medical school up to internship year at Imam Abdulrahman bin Faisal University (IAU) between June 2021 and January 2022. The questionnaire consisted of consent forms, sociodemographic data, and screening tools for PTSD, the GPIU, and PHQ-9.

Results: The prevalence of problematic internet usage (PIU) was 30.6% in the sample group. Students with moderate-to-moderately severe PTSD were 1.7 times more likely to have PIU OR (95% CI): 1.7 (1.091, 2.879). Students with moderate to severe depression were 2.2 times more likely to have PIU OR (95% CI); 2.2 (1.333, 3.950).Having a Saudi nationality, lower income, and being single was significantly associated with PIU.

Conclusion: Single Saudi medical students with lower income are at risk of developing more problematic internet use. Especially those who score moderate to high on PTSD and PHQ-9 scales.
