The IDS-15 (Pontes & Griffiths, 2017) was developed in a study that involved the participation of 1.105 English-speaking Internet users.
The IDS-15 has a total of 15 items that measure and conceptualize Internet addiction according to the four distinct latent domains: ‘Escapism and dysfunctional emotional coping‘, ‘Withdrawal symptoms‘, ‘Impairments and dysfunctional self-regulation‘, and ‘Dysfunctional Internet-related self-control‘.
