Σύνοψη	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.	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.
