IES-2 - Intuitive Eating Scale-2 - deutsche Version

Die IES-2 ist aus dem englischsprachigen Original adaptiert worden und erfasst intuitives Essverhalten im Erwachsenenalter. Sie umfasst 23 Items, die sich auf vier Subskalen (Bedingungslose Erlaubnis zu essen, Essen aus körperlichen anstatt aus emotionalen Gründen, Vertrauen in körperliche Hunger- und Sättigungssignale, Essen in Übereinstimmung mit körperlichen Bedürfnissen) verteilen. Reliabilität: Die interne Konsistenz nach Cronbach liegt zwischen Alpha = .73-.91. Validität: Eine Faktorenanalyse weist ein Vierfaktorenmodell nach. Zudem können Zusammenhänge zu verschiedenen Variablen (z. B. Geschlecht, Alter, Gewicht, Lebensqualität) aufgezeigt werden.

The IES-2 is the German translation of the English measure named the same (Tylka & Kroon Van Diest, 2013) and is used as a research instrument to investigate intuitive eating behaviour. It comprises 23 items on a five-step response scale, which are distributed over four subscales: UPE = Unconditional Permission to Eat, EPR = Eating for Physical rather than Emotional Reasons, RHSC = Reliance on Internal Hunger and Satiety Cues, B-FCC = Body-Food Choice Congruence. Reliability: The internal consistencies were Cronbach's Alpha = .91 for the total value and between Alpha = .72 and Alpha = .90 for the subscales. Overall, women achieved higher alpha coefficients (exception: B-FCC) than men. Validity: The factor structure of the IES-2 was investigated and retained for the subscales due to high charges. The negative correlations with the questionnaire on dietary behaviour (FEV-II), the Eating Disorder Inventory-2 - German version (EDI-2), the Interoceptive Awareness Questionnaire-expanded (IAQ-E) as well as the State Trait Anxiety Inventory - Trait version (STAI-Trait) act as evidence for the divergent validity. The age in men correlated weakly negatively with the IES-2 (r = -.12-.01). The IES-2 correlated negatively with the body mass index, whereby the values were neither very high for women nor for men. Other significant differences were found between healthy and clinical participants and within the facets of eating disorders.
