Conceptualisation of a Network Approach to Complete the Classification of Eating Disorders With the Aim of Better Personalising Their Management

Self-reported version of the gold-standard clinical interview for ED assessing the intensity of eating symptoms over the last 28 days. A total score as well as 4 sub-scores (restriction, diet, weight, shape) varying from 0 to 6 are thus obtained.

self-questionnaire of 34 items assessing body dissatisfaction and in particular four dimensions: avoidance and social shame of body exposure, body dissatisfaction with the lower parts of the body, use of laxatives and vomiting to reduce body dissatisfaction, maladaptive cognitions and behaviors in order to control weight. The total score ranges from 0 to 204. A score below 80 indicates no excessive body concerns, a score between 80 and 100 indicates mild concerns, between 111 and 140 moderate concerns, and a score above 140 indicates significant concerns

35-item Likert-type self-questionnaire assessing the difficulty or not in controlling the quantity of food one eats over the past 12 months, using an 8-point scale from "never" to "all days ". This questionnaire assesses clinical distress based on the DSM-5 diagnostic criteria for substance use disorders. Presenting clinically significant suffering and at least 2 diagnostic criteria suggest a food addiction.

multidimensional self-questionnaire of 22 items rated from 1 (completely disagree) to 5 (completely agree) aimed at assessing the sociocultural influence of the media on appearance. It includes four subscales: pressures, information, internalization relating to athletes and general internalization. The higher the score, the stronger the influence.

10-item self-questionnaire assessing the desire for muscularity in women. Each item is rated from 1 (never) to 6 (always). A high score indicates a significant search for musculature.

self-questionnaire of 21 questions evaluating the different types of exercises (normal and pathological) carried out over the last 4 weeks. A high score suggests physical hyperactivity linked to food and body concerns.

28-item self-questionnaire that assesses past history of childhood abuse. 5 forms of mistreatment are assessed: physical abuse and sexual abuse, emotional abuse and emotional neglect, as well as physical neglect.

self-assessment questionnaire measuring the severity of depression, composed of 9 items rated from 0 to 3. A total score varying from 0 to 27 is thus obtained. The higher the score, the more severe the depression.

self-questionnaire for assessing current anxious symptomatology consists of 7 items rated from 0 to 3. The total score ranges from 0 to 21. The recommended threshold for estimating generalized anxiety is 10.

Sleep disorders are common in EDs. The ISI is a self-questionnaire of 5 items rated from 0 to 4 which makes it possible to assess the nature of insomnia, satisfaction with sleep, daily functioning and anxiety in relation to sleep disorders. A total score varying from 0 to 28 makes it possible to assess the severity of insomnia.

This scale of 10 items rated from 1 (never) to 5 (always) assesses sensitivity to disgust and is used to calibrate the level of exposure during treatment. The higher the score, the more sensitive the subjects are to the emotion of disgust.

This scale includes 36 items and aims to assess difficulties in regulating emotions through 6 dimensions: N (Non-acceptance): non-acceptance of one's emotional response, G (Goals): difficulties in adopting goal-oriented behaviors in a negative emotional context, I (Impulse): difficulties in controlling oneself in a negative emotional context, A (Awareness): lack of emotional awareness, S (Strategies): difficulties in implementing emotion regulation strategies in an emotional context negative, C (Clarity): difficulty identifying one's own emotions. The higher the score, the more difficulty the subject presents in regulating their emotions.

measures from 0 to 10, in self-assessment, the intensity of discomfort and handicap felt in three areas of professional, social and family functioning.

24-item self-questionnaire measuring two aspects of neurocognitive functioning, rigidity (12 items) and lack of central coherence (12 items), as they manifest in a daily context. The two scores can vary from 12 to 72. The higher they are, the greater the perceived difficulties.

This is a test of copying and reproducing from memory a complex figure. The test draws on the subject's general intelligence abilities as well as their perceptual structuring skills. The purpose of the test in our study is to assess levels of central coherence (the ability to assess a situation as a whole rather than focusing on details).

cancellation test where individuals must search for target items "d" with two dots among distractors across a series of 658 consecutively ordered items. Participants are instructed to cancel as many target symbols as possible by moving across the page in a manner similar to reading from left to right with a limit of 20 seconds per trial without interruption. The ratio between the number of omission errors (number of "d"s with two unmarked points) and the total number of items processed was the main variable considered in this study.

This test explores executive functions using a set of 64 cards illustrated by the combination of three attributes: shape (cross, circle, triangle, star), color (yellow, red, blue, green) and number of figures (of 1 to 4). Four target cards are placed in front of the subject who must find a predetermined classification rule by trial and error. The results are expressed in number of categories completed, percentage of perseverative errors, number of trials necessary to complete the first category and learning capacity.

This task evaluates decision-making abilities in a situation of projection into the future and makes it possible to suggest prognoses for development in TCA.

The investigators want to study the link between the BMI and the alteration of the biological balance (ionogram, hetapic, liver function, hematogy corresponding to the standard biological assessment). (weight and height will be combined to report BMI in kg/m^2).

The investigators want to study the link between the disease duration and the alteration of the biological balance.

The investigators want to study the link between BMI and alteration of basal metabolism . (weight and height will be combined to report BMI in kg/m^2) Basal metabolims is the rate at which the body uses energy while at rest to maintain vital functions such as breathing and keeping warm (in Kcal per day)
