Podsumowanie	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 YFAS is a self-report questionnaire measuring symptoms of addictive-like eating behaviour in response to highly palatable foods. Developed by Gearhardt, Corbin, and Brownell in 2009, it is based on diagnostic criteria for substance use disorder and adapted to assess dependence-like symptoms related to food consumption. The YFAS 2.0, released in 2016, improved psychometric properties and reduced item burden. It is used in research on obesity, food addiction, and eating behaviour regulation.
