Prevalence of Internet-based addictive behaviors during COVID-19 pandemic: a systematic review.

With the outbreak of the COVID-19 worldwide pandemic, many countries have imposed lockdowns which have caused an increase in Internet use. As large-scale disasters may have an impact on addictions, a review on Internet-based addictive behaviors seems necessary. The goals of this review are to find whether Internet-based addictive behaviors have increased during the pandemic and to define the main reasons for this increase. The systematic search was conducted in Google Scholar, Science Direct, PsycINFO, and PubMed in October of 2020, to determine the current evidence and observations concerning the Internet-based addictive behaviors amid COVID-19. Studies were included if they considered the Internet-based addictive behaviors during the current pandemic. We used all the names of the coronavirus 2 (SARS-CoV2 previously 2019 nCoV), the name of the coronavirus disease 2019 (COVID-19), and common Internet-based addictive behaviors, namely Internet addiction, online gaming disorder, online gambling disorder, pornography use, and smartphone use disorder. The study design is PEOs, finding if individuals' exposure to the COVID-19 pandemic has caused an increase in Internet-based addictive behaviors. The quality of the studies was assessed independently by two authors using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The articles found in this review proved an increase in Internet-based addictive behaviors during the COVID-19 pandemic mostly due to financial hardships, isolation, problematic substance use, and mental health issues such as depression, anxiety, and stress. Effective interventions should be scaled up to prevent and reduce online addictive behaviors, as well as accessible guidelines, particularly for adolescents.
