The Eating Disorder-Specific Interoceptive Perception Questionnaire (EDIP-Q)<\/strong> is a specialized, psychometrically validated self-report assessment developed by Julie Ortmann, Annika P. C. Lutz, Gitta Rose, Christian Happ, Claus V\u00f6gele, Andr\u00e9 Schulz, and Zo\u00e9 van Dyck (2023, 2024). It was engineered to address a critical assessment gap in clinical psychology and psychiatric psychodiagnostics: the accurate, nuanced measurement of an individual's capacity to perceive, process, and differentiate internal bodily signals related to food intake and emotional experience. Interoceptive disruption\u2014the impaired awareness or misinterpretation of afferent physiological signals arising from the visceral autonomic system\u2014has long been conceptualized as a foundational transdiagnostic vulnerability factor in eating disorders (EDs)<\/a>, including anorexia nervosa<\/a> (AN), bulimia nervosa<\/a> (BN), and binge-eating disorder<\/a> (BED).<\/p>\n Developed through a rigorous multi-stage psychometric pipeline involving extensive item generation from legacy measures, comprehensive scrutiny by a multidisciplinary panel of clinical experts, and rigorous empirical validation across two independent German adult samples ($N = 1,269$<\/span> total across phases), the final instrument consists of 25 items structured across four distinct first-order dimensions: Hunger<\/em> (5 items), Satiety<\/em> (7 items), Emotions<\/em> (7 items), and Discrimination<\/em> between hunger and emotional states (6 items). Items are calibrated along a 7-point Likert scale (1 = Does not apply at all<\/em> to 7 = Applies completely<\/em>), wherein lower composite and subscale scores directly index more severe deficits in interoceptive processing<\/span>.<\/p>\n Psychometric evaluations demonstrate excellent internal consistency, with a total scale Cronbach's $\\alpha$<\/span> of .94 and subscale coefficients ranging from .86 to .93. Structural equation modeling and exploratory\/confirmatory factor analyses corroborate both a robust four-factor correlated model (CFI = 0.95, TLI = 0.94, RMSEA = 0.052, SRMR = 0.047) and a hierarchically organized second-order global EDIP construct (CFI = 0.95, TLI = 0.94, RMSEA = 0.053, SRMR = 0.050). The scale demonstrates pronounced construct, convergent, and discriminant validity, effectively differentiating individuals with diagnosed eating pathology from non-clinical controls, while mapping distinct interoceptive profiles across anorexia, bulimia, and binge-eating diagnostic phenotypes. The EDIP-Q provides an indispensable assessment framework for both clinical psychopathology research and precision treatment planning<\/span>.<\/p>\n Eating Disorders, Interoceptive Perception, Interoceptive Awareness, Hunger, Satiety, Emotion Discrimination, Anorexia Nervosa, Bulimia Nervosa, Binge-Eating Disorder, Psychodiagnostic Measures, Visceral Sensitivity, Psychometrics<\/p>\n The Eating Disorder-Specific Interoceptive Perception Questionnaire was designed and validated by an international team of behavioral scientists, clinical psychologists, and psychophysiologists based primarily at the University of Luxembourg:<\/p>\n Institutional Correspondence Address:<\/strong> The primary clinical and psychometric purpose of the Eating Disorder-Specific Interoceptive Perception Questionnaire (EDIP-Q) is to provide an objective, granular, and empirically robust assessment of eating disorder-specific interoceptive deficits. While broad psychiatric instruments like the Eating Disorder Inventory<\/a> (EDI; Garner et al., 1983) and general interoception inventories such as the Multidimensional Assessment of Interoceptive Awareness (MAIA; Mehling et al., 2012) or the Body Perception Questionnaire (BPQ; Porges, 1993) capture facets of somatic awareness, they frequently fail to differentiate visceral gastrointestinal homeostatic signaling (e.g., gastric mechanoreceptive stretching, ghrelin-mediated appetite onset) from subjective emotional distress (e.g., anxiety, sadness, irritability). Consequently, researchers and clinicians have historically lacked a single, psychometrically sound instrument explicitly dedicated to quantifying the intersection of nutritional homeostatic processing and emotional differentiation.<\/p>\n Clinically, the EDIP-Q serves three foundational functions:<\/p>\n The central psychological construct operationalized by the EDIP-Q is Eating Disorder-Specific Interoceptive Perception (EDIP)<\/strong>. Historically defined by Sherrington (1906) and modernized by neurobiologists such as A. D. Craig<\/a> (2002) and Hugo Critchley (2004), interoception<\/a> encompasses the ongoing afferent neural reception, central representation, integration, and subjective appraisal of physiological signals originating within the internal visceral organs (e.g., heart rate, gastric motility, respiratory status, thermal state, and blood glucose fluctuations). In the context of eating pathology, interoception is not a monolithic trait; rather, it is a multi-compartment construct composed of four interrelated yet functionally autonomous cognitive-perceptual dimensions:<\/p>\n This subscale captures an individual's sensitivity, timing, and acuity in recognizing endogenous energy-depletion cues. Biologically mediated by descending neuroendocrine cascades (involving hypothalamic arcuate nucleus stimulation, ghrelin<\/a> secretion, and vagal afferent firing triggered by gastric emptiness and rhythmic migrating motor complexes), normative hunger perception allows individuals to register somatic appetite before entering extreme physiological starvation. In the EDIP-Q, this construct measures whether the respondent can easily sense stomach rumbles and energy drops, or whether awareness remains absent until extreme physical depletion occurs (e.g., Item 6: "I do not realize that I am hungry until I am extremely hungry"<\/em>; Item 11: "Even when I have not eaten anything for a long time, I do not feel hunger"<\/em>).<\/p>\n Satiety perception reflects the conscious registration and hedonic evaluation of visceral signals indicating energy sufficiency and gastrointestinal filling. These cues rely upon gastric mechanoreceptors signaling muscular wall stretching via the vagus nerve, paired with postprandial release of anorexigenic hormones including cholecystokinin<\/a> (CCK), peptide YY (PYY), and glucagon-like peptide-1<\/a> (GLP-1). Individuals with high satiety awareness readily distinguish between comfortable nutritional satisfaction and painful overfullness (e.g., Item 10: "I notice when I reach a point of comfortable satiation"<\/em>). Conversely, severe deficits are manifested as an inability to detect termination signals until acute discomfort, nausea, or stomach overdistension ensues (e.g., Item 13: "I do not notice that I am full until I have completely stuffed myself"<\/em>).<\/p>\n Interoception provides the somatic bedrock for emotional feeling states, consistent with the James-Lange and Schachter-Singer models of emotion and modern neuroimaging evidence of insular cortex recruitment during affective processing. The Emotion Perception<\/em> subscale of the EDIP-Q evaluates subjective emotional clarity and interoceptive sensibility regarding affective states\u2014such as recognizing feelings of sadness, anxiety, anger, or joy. Individuals with impairments in this domain struggle with affective awareness (bordering on alexithymia<\/a>), experiencing emotional distress as an undifferentiated, diffuse bodily unease (e.g., Item 2: "I can recognize my emotions easily"<\/em>; Item 21: "I can recognize when I feel sad, angry, or anxious well"<\/em>).<\/p>\n Perhaps the most clinically vital dimension of the EDIP-Q is the capacity to disentangle nutritional homeostatic cues from autonomic sympathetic arousal accompanying affective states. Visceral sensations triggered by psychological stress, anxiety, excitement, or dysphoria\u2014such as epigastric fluttering, visceral tension, autonomic hyperarousal, or gastric cramping\u2014share overlapping afferent pathways with true metabolic hunger. Patients with eating pathology frequently display profound interoceptive confusion<\/em>, misidentifying emotional discomfort as somatic hunger, or experiencing the physical sensations of emotional turmoil as an urge to consume food (e.g., Item 5: "I do not feel a difference between hunger and stress"<\/em>; Item 18: "I do not feel a difference between hunger and sadness"<\/em>; Item 7: "Hunger and emotions feel the same to me"<\/em>). Successful discrimination prevents emotionally driven eating, compensatory behaviors, or maladaptive food avoidance.<\/p>\n The architecture of the EDIP-Q is rooted in over six decades of psychiatric, cognitive-developmental, and neurobiological theory regarding the etiology and maintenance of eating disorders:<\/p>\nKeywords<\/h2>\n
