Problematic usage of the internet: converging and diverging terminologies and constructs

Problematic usage of the internet (PUI) is an increasing global concern, leading to significant negative impacts in various levels. PUI is an umbrella term comprised of subcategories, including online gaming disorder, online gambling disorder, online buying-shopping disorder, online compulsive sexual behavior disorder, problematic usage of social media, cyberchondria, cyberbullying, and digital hoarding. With respect to the diversity of these categories, a factor that further impedes the field of PUI is not recognizing these subcategories under the PUI. To estimate the state of the field, we conducted a systematic review on a sample time frame, 2022–2023, and we found that among 2,497 relevant papers, only 13% of the studies on PUI subcategories used PUI as an umbrella term. Establishing PUI as an overarching terminology, as we do with substance use disorder (SUD) as a term while respecting the diversities within its subcategories, would synergize research efforts, facilitate comparisons, and inform treatment strategies. As technology continues to evolve, terminological refinement is critical to maintaining relevance and accessibility for researchers and the broader community.
