“…In comparison to the Internet Addiction Test (IAT; Young, 1998), the most used instrument for assessing PIU, the GPIUS2 is specifically focused on problematic use that arises due to the unique communicative context of the Internet. For these reasons, both the first and the second version of the GPIUS have been used recently in a variety of contexts for the assessment of GPIU (e.g., Ang, Chong, Chye, & Huan, 2012;Casale & Fioravanti, 2011;Casale, Tella, & Fioravanti, 2013;Chittaro & Vianello, 2013;Fioravanti et al, 2012;Fioravanti, Primi, & Casale, 2013;Gámez-Guadix et al, 2012) with the aim of reporting the properties of the scale across various cultures. Among Mexican adolescents, the GPIUS2 has demonstrated adequate psychometric qualities, including construct validity, convergent validity, and internal consistency (Gámez-Guadix et al, 2012).…”
