YFAS is designed as a self-administered questionnaire that screens for symptoms of food addiction by asking respondents to report their own behaviors and experiences. Because it relies on self-report rather than a clinician conducting an interview, there’s no need for blood tests or imaging. The instrument is kept concise so it can be completed efficiently in a single sitting, and the typical completion time is around 10 minutes. A 30-minute clinician interview would not reflect its self-report, and a 5-minute completion is usually too short to capture the full set of items. Therefore, describing it as a self-reported measure that takes about 10 minutes best matches how YFAS is commonly used.
