Methods
Study 1 assessed the content validity of the scale through ratings of clinical and research experts in the field. Study 2 inspected the scale through exploratory and confirmatory factor, parallel, correlation, and reliability analyses. Study 3 assessed the temporal stability through a test–retest in a 2-week interval. Study 4 assessed the scale in a randomized control experimental design, where a mindful eating (vs. control group) received the trait scale before consuming chocolate, and an equivalent state scale was modified to assess state changes during the 10-min eating session.
