Abstract

Intuitive eating is based on a strong physical connection with the body, aligned to internal cues of hunger and satiety, and a low preoccupation with food. The aim of this study was to provide a German version of the Intuitive Eating Scale-2 (IES-2) and to examine its psychometric properties with data collected from 532 participants aged 18-91 years. The IES-2 was translated into German following the World Health Organization guidelines (2016). Cronbach's alpha as a measure of internal consistency was 0.89 for the IES-2 total score, as well as 0.73 - 0.92 for the IES-2 subscale scores. For group differences, the results were as hypothesized: men had higher IES-2 scores than women, and participants with under- and average weight showed higher IES-2 scores than participants with overweight and obesity. Participants without a dieting history had higher IES-2 scores than former or current dieters. In line with our hypotheses regarding construct validity, the IES-2 score had negative associations with emotional eating, restraint eating, external eating, binge eating and eating disorder symptomatology, as well as positive associations with self-efficacy and mental health-related quality of life. Second-order confirmatory factor analysis replicated the four-factor solution, with intuitive eating as a higher-order factor. These findings demonstrate that the German version of the IES-2 is a useful tool to assess intuitive eating in the general German population.
