The objective of this study was to examine the content validity and test–retest reliability of the Intuitive Eating Scale among pregnant women. A qualitative think-aloud study of the Intuitive Eating Scale analysed the content validity. Overall, the Intuitive Eating Scale made sense to pregnant women, but food safety affected the interpretation of some items. A version with instructions modified accounting for food safety, the Intuitive Eating Scale–Pregnancy, was subsequently shown to have stable scores over 5 weeks during the second trimester, mean change = –0.08 (95% limits of agreement: –0.61 to 0.45), r = 0.79, n = 240. The Intuitive Eating Scale–Pregnancy was acceptable for use in this New Zealand pregnant population.
