Approximately how long does it typically take to complete the YFAS?

• A. 90 minutes.
• B. 2 minutes.
• C. 10 minutes.
• D. 45 minutes.

Answer: (C)

The YFAS is designed to be completed relatively quickly as a self-report screening. In typical administration, most respondents finish in about 10 minutes. This duration reflects enough time to read and respond to the items about eating behaviors, cravings, and related impacts without making the assessment overly burdensome in clinical or research settings. The other durations are less plausible: 2 minutes is usually not enough to thoughtfully complete all items, while 45 or 90 minutes would imply a much longer, more in-depth interview than the standard YFAS typically requires. If you’re using the full YFAS 2.0 in some contexts, it can take somewhat longer (often around 15–20 minutes), but a common practical estimate remains around 10 minutes.
