The table shows Spearman correlations (ρ) between the number of affirmed SND and IGD criteria (assessed on-site for Study 1 and online for Study 2) and internet use, impulsivity, and personality. SND, social network use disorder; IGD, internet gaming disorder; CIUS, Compulsive Internet Use Scale; IAT, Internet Addiction Test; BIS−15, Barrat Impulsiveness Scale – short version; I−8, Scale Impulsive Behavior−8; BFI−10, Big–Five–Inventory−10.

On–site assessment,

online assessment.

Time spent on social networking sites and Serenko scales adapted to social network use were correlated with SND criteria, and time spent on internet gaming and Serenko scales adapted to internet gaming were correlated with IGD criteria.
