Adherence
The Modified Yale Food Addiction Scale Version 2.0 (mYFAS 2.0) is a psychometrically valid, 13-item screening tool that performs similarly to the full 35-item YFAS 2.0 in assessing addictive-like eating behaviors, making it suitable for large-scale studies where participant burden is a concern.
If you are designing a study or assessment on eating behaviors and need to minimize participant burden, use the mYFAS 2.0. It is a 13-item questionnaire that has been validated to perform similarly to the longer 35-item version, providing reliable data on addictive-like eating patterns without requiring excessive time from participants.
The mYFAS 2.0 and YFAS 2.0 performed similarly on indexes of reliability, convergent validity with related constructs (e.g. weight cycling), discriminant validity with distinct measures (e.g. dietary restraint) and incremental validity evidenced by associations with frequency of binge eating beyond a measure of disinhibited eating.
Why this rating
The study uses two independent samples (n=536 and n=213) and demonstrates good reliability (KR-20=0.86) and validity (convergent, discriminant, incremental).
