“…The EDE-Q has shown satisfactory concurrent and criterion validity in previous research and excellent internal consistency and test-retest reliability [32]. Prior non-clinical research has shown strong inverse relationships between scores on the IES-2 and scores on the EDE-Q for both the total global score and all individual subscales [3]. In the current sample, internal consistency was high for both the global score (0.92) and the individual subscales; restraint (0.83), weight concern (0.84), shape concern (0.90), and eating concern (0.75).…”

“…Despite being widely used, several aspects of this common measure remain unclear. First, though the IES-2 has a well-documented four-component structure in research using non-clinical samples [3,10,40], evidence as to whether the hypothesised four-component structure will replicate in clinical populations is not yet known. Understanding and validating the structure in a clinical context is important to clarify whether or not the IES-2 is suited to this population and whether scores can be interpreted as intended.…”

Intuitive Eating Scale-2: psychometric properties and clinical norms among individuals seeking treatment for an eating disorder in private practice

et al. 2021

Purpose Intuitive Eating (IE) is an approach to eating designed to facilitate a positive relationship with food. Its use in clinical settings and in the community is rapidly growing in popularity. The Intuitive Eating Scale 2 (IES-2) is a widely used measure that indexes intuitive eating motivations and behaviour, however evidence of its validity in populations with clinical eating disorders remains scarce. The objective of the proposed study was thus to evaluate the factor structure of the IES-2 in a large sample of individuals seeking treatment for eating disorders in private practice. Methods Data collected from 569 women and men aged 12-68 years seeking treatment for an eating disorder in one of eight specialist private outpatient eating disorder clinics were examined using confirmatory factor analysis (CFA). Relationships between IES-2 scores and measures of psychopathology were also examined. Results Results were relatively consistent with the purported four-factor structure of the IES-2. The measure displayed strong construct validity and good internal consistency. Scores on the IES-2 were inversely associated with scores of depression, anxiety, and disordered eating, providing evidence for divergent validity of the measure. Clinical norms are provided for anorexia nervosa (AN) spectrum disorders and bulimia nervosa (BN) spectrum disorders, as well as for the clinical sample as a whole. Conclusion Findings suggest that the IES-2 may be an appropriate measure for evaluating behaviours relating to IE in community outpatient eating disorder settings, and provide further evidence for the association between IE and positive health outcomes. Level of evidence III, evidence obtained from well-designed cohort or case-control analytic studies.

“…This IES utilizes a three-factor model (unconditional permission to eat, eating for physical rather than emotional reasons, reliance on internal hunger/satiety cues) as opposed to Hawk's four-factor IES [10] . Most scholars currently agree that the IES developed by Tylka better re ects individual IE [12,18,19,20] .…”

Intuitive eating (IE) is largely considered to be engaging in behaviors consistent with eating in reaction to one’s physiological appetite and fullness signals instead of environmental stimuli and emotional cues. The Intuitive Eating Scale-2 (IES-2) was developed in order to assess the outlook and behaviors of eating on four subscales: unconditional permission to eat (UPE), eating because of physiological as opposed to emotional reasons (EPR), dependence on physiological hunger and satiety cues (RHSC), and body-food choice congruence (B-FCC). Obesity is a frequent comorbidity in Chinese patients with hypertension and nearly 3/4 of such patients have eating problems. The current study intended to validate the psychological measurement properties of the IES-2 Chinese Version (IES-2-Chi) in an obese population with hypertension. For the IES-2-Chi, Cronbach's ɑ = 0.947, split-half reliability was 0.850, the test-retest reliability was 0.889, chi-square/degree of freedom ratio (χ2/df) = 1.318, root mean square error approximation (RMSEA) = 0.040, root mean square residual (RMR) = 0.053, goodness-of-fit index (GFI) = 0.902, comparative fit index (CFI) = 0.982, Tucker-Lewis index (TLI) = 0.978, incremental fit index (IFI) = 0.983, and normal fit index (NFI) = 0.932. The secondary study objective was to evaluate IE levels of obese Chinese patients with hypertension. IE was correlated positively with self-efficacy, body image, and frequency of eating vegetables and fruits, but negatively with body mass index, hemoglobin, diastolic blood pressure, hematocrit, total cholesterol, low-density lipoprotein, and frequency of eating fast food.Conclusion: The current study demonstrates that the IES-2-Chi has good reliability and validity in obese patients with primary hypertension and can be used to evaluate IE levels of these patients. Based on the current study results, future studies may be designed to develop intervention strategies using IE to utilize its influential factors in obese patients with primary hypertension.

“…Research has demonstrated that the IES-2 is a reliable and valid instrument in assessing intuitive eating across different ethnic populations (Bas et al, 2017;Camilleri et al, 2015;Carbonneau et al, 2016;Tylka & Kroon Van Diest, 2013). However, a literature gap exists in the following aspects.…”

Validating the Persian Intuitive Eating Scale-2 Among Breast Cancer Survivors Who Are Overweight/Obese

et al. 2020

Women with breast cancer are at risk of being overweight/obese which may consequently increase mortality. Intuitive eating is an adaptive eating behavior which might be beneficial for weight outcomes. The present study validated the Persian Intuitive Eating Scale-2 (IES-2) among overweight/obese Iranian females with breast cancer. Women who were overweight/obese with breast cancer (n = 762; mean ± SD age = 55.1 ± 5.7 years) completed the following questionnaires: IES-2, General Self-Efficacy Scale (GSE-6), Hospital Anxiety and Depression Scale (HADS), Short Form-12 (SF-12), Weight Bias Internalization Scale (WBIS), Body Appreciation Scale-2 (BAS-2), and Eating Attitudes Test (EAT-26). Confirmatory factor analysis (CFA) and Rasch analysis were applied to examine the psychometric properties of the IES-2. Associations between IES-2 score and other scale scores were assessed. CFA and Rasch analysis suggested that the Persian IES-2 had robust psychometric properties and all IES-2 items were meaningful in their embedded domains. The four-factor structure of the Persian IES-2 was confirmed. Concurrent validity was supported by the positive correlations between the IES-2 score and scores on the GSE-6, SF-12 mental component, and BAS-2. Negative correlations were found between the IES-2 score and the HADS (anxiety and depression subscales), WBIS, and EAT-26. The present study demonstrated that the Persian IES-2 is a well-designed instrument and is applicable for women who are overweight/obese with breast cancer.
