Tiivistelmä	The PSUS is a self-report questionnaire measuring compulsive smartphone use, withdrawal symptoms, and loss of control related to mobile devices. Developed by Hussain, Griffiths, and Sheffield in 2017, it targets the growing phenomenon of smartphone addiction in the digital age. The PSUS captures how smartphone dependence differs from general internet addiction, with particular focus on the constant connectivity and notification-driven engagement of mobile devices. Related instruments include the Smartphone Addiction Scale (SAS) by Kwon and colleagues, which focuses on adolescents.	The PGSI (Problem Gambling Severity Index) is a 9-item self-report questionnaire measuring problem gambling severity and gambling disorder risk. Developed by Ferris and Wynne in 2001 for the Canadian Centre on Substance Use and Addiction, it is one of the most widely used screening tools for gambling disorder in English-speaking countries. The PGSI assesses gambling frequency, loss of control, negative consequences, and harm from gambling. It is available freely and has been translated into multiple languages.
