Eating Disorder-Specific Interoceptive Perception Questionnaire – EDIP-Q
Measures the capacity for perceiving and distinguishing between emotions, hunger, and satiety, particularly within the context of eating disorders.
Scale Development & Technical Details
Scale Overview
The Eating Disorder-Specific Interoceptive Perception Questionnaire – EDIP-Q was developed by Julie Ortmann, Annika P. C. Lutz, Gitta Rose, Christian Happ, Claus Vögele, André Schulz, Zoé van Dyck (2023). It is designed to measure Eating Disorder-Specific Interoceptive Perception. The scale is intended for use with Adults.
Scale Structure
This instrument consists of 25 items organized into 4 factors/subscales: Emotion, Hunger, Satiety, Discrimination.
| Factor / Subscale | Items | N |
|---|---|---|
| Emotion | 2,9,12,15,19,21,23 | 7 |
| Hunger | 1,6,11,16,25 | 5 |
| Satiety | 4,8,10,13,17,20,24 | 7 |
| Discrimination | 3,5,7,14,18,22 | 6 |
Response Format
Respondents rate each item using a custom response format.
Response anchors: 1 = Does not apply at all, 2 = 2, 3 = 3, 4 = 4, 5 = 5, 6 = 6, 7 = Applies completely.
The scale includes 11 reverse-scored items to reduce acquiescence bias.
Scoring
Items are scored by subscale, with each subscale sum representing a distinct dimension.
Total scores range from 25 to 175. Interpretation guidelines:
- Severe difficulty in eating disorder-specific interoceptive perception: 25 – 75
- Moderate difficulty in eating disorder-specific interoceptive perception: 76 – 125
- Minimal difficulty in eating disorder-specific interoceptive perception: 126 – 175
Psychometric Properties
Internal Consistency: The scale has demonstrated good to excellent internal consistency with reported Cronbach’s alpha values of Cronbach's alpha: .94 (Total), .92 (Emotions), .86 (Hunger), .93 (Satiety), .88 (Discrimination).
Administration
The scale is self-administered and typically takes approximately 5 minutes to complete. It can be administered individually or in group settings. No special training is required for administration.
