| Zusammenfassung≠ | The IAT is a 20-item self-report questionnaire designed to measure problematic internet use and internet addiction. Developed by Kimberly Young in 1998, it was one of the first validated screening tools for internet-related compulsive use. The IAT assesses loss of control, salience (preoccupation with internet), withdrawal symptoms, and negative consequences. It remains widely used in research on internet addiction, particularly in adolescents and young adults. | 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. |
