<p>The Intuitive Eating Scale-2 (IES-2) is currently used for this concept and consists of four sub-dimensions. This cross-sectional study aimed to determine the validity and reliability of the culturally and linguistically adapted IES-2, which examines multiple aspects of eating behavior in adults, in the Turkish adolescent population for the first time. The factor structure of the IES-2 was evaluated in study 1 (<i>n</i> = 300, 57.7% girl) using exploratory factor analysis (EFA), and in study 2 (<i>n</i> = 470, 60.9%) with confirmatory factor analysis (CFA). The Figure Rating Scale (FRS), the Emotional Eating Scale Adapted for Use in Children and Adolescents Scale (EES-C), the Children’s Eating Attitudes Test (ChEAT), and BMI-<i>Z</i> score were used to assess convergent validity, and their relationship with IES-2 was examined. Cronbach-<i>α</i>, McDonald’s omega, Spearman–Brown, and Guttman split-half coefficients were used for reliability analysis. The four-factor structure of the IES-2 was obtained through EFA, and items with low factor loadings were removed. The 15-item version of the scale was created and verified by CFA. The new scale adapted for adolescents is the IES-2-Turkish adolescents (IES-2-TA). Good fit index values were achieved because of CFA. The Cronbach-<i>α</i> coefficients for the sub-dimensions (unconditional permission to eat—UPE: 0.649, eating for physical reasons–EPR: 0.683, relying on hunger and satiety cues—RHSC: 0.871, body–food choice congruence—BFCC: 0.751) and total scale (0.789) were found to be at good values. A negative correlation was found between IES-2-TA and ChEAT, as well as EES-C, for convergent validity. </p><p> <i>Conclusion</i>: The analysis of data revealed that the new version of the IES-2-TA is a reliable and valid instrument to assess intuitive eating in Turkish adolescents.<Table Float="No" ID="Taba"> <tgroup cols="2"> <colspec align="left" colname="c1" colnum="1" /> <colspec align="left" colname="c2" colnum="2" /> <tbody> <row> <entry nameend="c2" namest="c1"> <p><b>What is Known:</b></p> <p>• <i>Intuitive eating is an eating behavior that emphasizes internal bodily cues to guide food decisions.</i></p> <p>• <i>There is no scale to measure intuitive eating in children and adolescents in Turkey.</i></p> </entry> </row> <row> <entry nameend="c2" namest="c1"> <p><b>What is New:</b></p> <p>• <i>This scale (IES-2-TA), adapted from the adult IES-2, is valid and reliable for assessing intuitive eating in Turkish adolescents.</i></p> </entry> </row> </tbody> </tgroup> </Table></p>
