Abstract

Objective: Individuals with Avoidant Restrictive Food Intake Disorder (ARFID) experience impairing health consequences from insufficient nutritional variety and/or quantity. Early medical conditions and/or somatic symptoms such as abdominal pain may lead some with ARFID to experience somatic sensations as aversive. As such, food avoidance may be part of a broader behavioral repertoire aimed at suppressing bodily sensations. Avoiding these necessary and informative signals (e.g., growls of hunger) may subvert the emergence of healthy self-awareness and self-regulation. Teaching children with ARFID to engage adaptively with bodily sensations may help decrease aversiveness, increase self-awareness, and increase approach behaviors. Method: Drawing from interventions for panic disorder and irritable bowel syndrome, we developed an acceptance-based interoceptive exposure treatment for young children with ARFID, Feeling and Body Investigators (FBI)-ARFID Division. Using playful cartoons and developmentally sensitive exposures, we teach young children how to map interoceptive sensations onto meanings (e.g., emotions) and actions (e.g., if I feel nervous, I'll hold someone's hand). Results: We present a case study of a 4-year old child with lifelong poor appetite/food indifference. Discussion: Some individuals with ARFID may avoid food to avoid internal sensations. Developmentally appropriate interoceptive exposures may decrease ARFID symptoms while increasing more general self-regulation skills. © 2018 Wiley Periodicals, Inc.

  • Premisecitation

    Exposures that deliberately provoke interoceptive sensations should aim to disconfirm negative outcome expectancies.

    “According to this model, exposures that intentionally provoke interoceptive sensations should be designed to disconfirm underlying expectancies of negative outcomes (e.g., I can’t handle pain; Craske et al., 2014).”

  • Premisecitation

    Pain-avoidance learning models may guide ARFID treatment.

    “Learning models of pain avoidance may inform ARFID treatment approaches (Vlaeyen & Linton, 2000).”
    Quote in the paperSubstantial claim1 of 1 sources checked
    • cites Vlaeyen & Linton, 2000 source

      Sections 3 and 4 describe learning models of pain avoidance, and Section 13 discusses using the fear-avoidance model to guide treatment for musculoskeletal pain. Our copy does not address ARFID or propose applying the model to its treatment, so that extension is not supported by this source. (LLM, conf=0.86)

      Experimental — accuracy not yet measured
  • Premisecitation

    Interoceptive exposure is more effective when it closely mimics the avoided experience and creates an expectancy violation.

    “The degree to which these exposures more closely replicate the avoided experience (e.g., provoking a strong sensation) and create an expectancy violation (i.e., helping the individual to learn that outcomes differ from expectations), the more effective the interoceptive exposure.”

  • Premisereasoning

    Pain may enhance learning and memory mechanisms.

    “Given the importance of pain and the recognition and avoidance of pain for survival, it is logical that pain may facilitate mechanisms to increase learning and memory (Vlaeyen & Linton, 2000).”
    Quote in the paperNot a substantial claim1 of 1 sources checked
    • cites Vlaeyen & Linton, 2000 source

      Section 3 (‘Model 1: the “activity” avoidance model’; page unavailable) describes learning to predict pain and avoid situations associated with it. That supports pain-related avoidance learning, but the paper does not say that pain enhances memory or learning mechanisms generally; a search for memory found no supporting passage. (LLM, conf=0.84)

    Premisecitation

    Many people with ARFID experience somatic, interoceptive, or sensory sensations as aversive and act to suppress them.

    “Early medical conditions and/or somatic symptoms such as abdominal pain may lead some with ARFID to experience somatic sensations as aversive.”
    • Also stated in: § Introduction · hedged
      “one process that may be relevant for many individuals with ARFID is the experience of somatic/interoceptive or sensory sensations as aversive and the engagement in behaviors created to suppress these sensations.”

      The Results (page unavailable) report abdominal pain as a trigger for eating disturbance in five children and document fear of vomiting, supporting a possible link between bodily symptoms and food avoidance. The paper does not establish that early medical conditions cause people with ARFID to experience somatic sensations as aversive, or that they act to suppress those sensations. (LLM, conf=0.81)

    Interpretationcitation

    Early aversive experiences of sensations may disrupt this mapping, hindering self-awareness and leading to conditions and symptoms that mute bodily sensations.

    “The experience of sensations as aversive early in development may disrupt this mapping - preventing the emergence of self-awareness and leading to conditions and symptoms intended to mute bodily sensations (Zucker et al., 2017).”
    Quote in the paperSubstantial claim1 of 1 sources checked
    • cites Zucker et al., 2017 source

      The Discussion (page unavailable) says that fear of bodily sensations can lead to suppression or avoidance, muting informative sensations and potentially hindering the development of capacities such as emotional self-regulation. It does not specifically say that this disrupts a developmental mapping or prevents self-awareness from emerging, or that the resulting conditions and symptoms are intended to mute sensations.

    Interpretationreasoning

    Aversive reactions and sensitivity to digestive-tract sensations may contribute to food avoidance in ARFID.

    “Sensitivity and aversive reactions to sensations from various parts of the digestive tract could contribute to food avoidance (e.g., oral sensitivity to taste/texture; esophageal sensitivity to feelings of gagging and choking; bloating from constipation contributing to aversive feelings of fullness).”

    Interpretationreasoning

    Sophie appeared to have a nervous system highly sensitive to change, with intense arousal impairing eating, preschool attendance, and coping with routine changes.

  • The paper relies on this without support.

    Interoceptive sensations carry information and communicate needs such as hunger or fatigue, or signal emotional experience.

    “since interoceptive sensations are informative and communicate needs such as hunger or fatigue or signal emotional experience, it was important to give children tools to help decipher their meaning and link these sensations to adaptive actions that meet particular needs.”
  • The paper relies on this without support.

    ARFID often begins in early childhood.

    “This is particularly crucial given the age of onset of ARFID, often in early childhood.”
  • The paper relies on this without support.

    Mapping interoceptive states onto meaning and action is the foundation of healthy self-awareness.

    “The mapping process is the foundation of healthy self-awareness.”
  • The paper relies on this without support.

    Pain is a danger signal, so linking fear with pain is adaptive.

    “That is, since pain is a danger signal, it would be adaptive for fear and pain to be linked.”
  • The paper relies on this without support.

    Children with ARFID may have a trait-like sensitivity to interoceptive and exteroceptive sensations.

    “Given that children with ARFID may exhibit sensitivity to interoceptive and exteroceptive sensations as a trait feature, we provided children with a framework whereby they can perceive these sensations with curiosity rather than fear, in order to learn to tolerate the sensations.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read under definition version 3 (extract-v3) on 2026-09-28.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-09-28.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
