Validation of the Intuitive Eating Scale in pregnancy.

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 5weeks 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.
