Mindful eating has gained attention in studies on healthy eating. However, measurement of it is scarce, particularly in pediatrics. This study aimed to translate and modify the 12-item Mindful Eating Questionnaire for Children (MEQ-C) using techniques based on both classical test theory (ICC) and item response theory (IRT) in Chinese children and adolescents. Of the 426 participants enrolled and randomly grouped, the test (n = 223) and validation (n = 203) subsamples were well-matched in age, gender, body mass index z score (BMIz), and waist to height ratio (WHtR) (p > 0.556). Three items were eliminated due to deviating from the mindful eating concept (content validity index < 0.71) and presenting as an independent dimension in parallel analysis, or yielding a poor distribution (−4.331 < b < −0.111). The final 5-item Mindless Eating and 4-item Awareness subscales were identified with sound Cronbach’s α of 0.802 and 0.779, respectively. The remaining items functioned well (a > 1, −3 < b < 3), and the Mindless Eating subscale was accurate for the low-to-medium range (−2 to 0) of the mindful eating measure. The Awareness one was reliable for the relatively high range (0 to 2). Participants’ mindful eating characteristics should be taken into consideration in practice.
