How do people with unexplained symptoms perceive their bodies?
People with unexplained physical symptoms do not detect bodily signals more intensely, but they struggle more with worrying, ignoring, and trusting their physical sensations.

Altered Interoceptive Awareness in High Habitual Symptom Reporters and Patients With Somatoform Disorders
What they did
In the first study, researchers screened 486 individuals to select 32 high habitual symptom reporters and 32 low habitual symptom reporters, measuring their patterns of bodily awareness. In the second study, they evaluated 26 patients with a somatoform disorder, 25 patients with major depressive disorder, and 26 healthy controls using structured clinical interviews and self-report scales to examine specific dimensions of internal body perception.
What they found
While participants with unexplained symptoms did not differ from controls in basic physical tracking, high symptom reporters showed significantly greater worry about pain, reflected in lower scores on the Not-Worrying scale with an effect size of 0.14. Additionally, clinical patients diagnosed with somatoform disorders reported viewing their bodies as less safe and trustworthy compared to healthy controls, showing a large reduction in Trusting scores with an effect size of 0.28.
The limits
What it doesn't show
This research relies purely on subjective questionnaires and does not incorporate objective physiological indicators, leaving it unclear if actual bodily signals differ. The cross-sectional design prevents drawing conclusions about whether altered bodily awareness causes medically unexplained symptoms or is merely a psychological response to chronic discomfort. Finally, the relatively small sample sizes and the fact that most somatoform patients specifically suffered from pain disorders mean these patterns might not generalize to all types of unexplained somatic conditions.
Key terms
- interoception
- The physiological and cognitive process through which an organism senses, interprets, and integrates signals originating from within its own body.
- somatoform disorders
- A category of mental health conditions marked by chronic physical symptoms that cause significant distress but lack a detectable organic medical cause.
- medically unexplained symptoms
- Somatic complaints, such as persistent pain or exhaustion, for which routine medical evaluations fail to find a structural or pathophysiological explanation.
- interoceptive awareness
- The conscious monitoring, evaluation, and psychological appraisal of internal physical sensations and bodily states.
- somatosensory amplification
- A cognitive tendency to intensely focus on, hyper-analyze, and catastrophize minor or benign physical sensations.
- multidimensional assessment of interoceptive awareness
- A standardized self-report questionnaire designed to measure eight distinct cognitive and attentional facets of internal body perception.

Common questions
Did patients with unexplained physical symptoms actually notice internal bodily changes more than healthy people?
No, the study found no significant differences on the Noticing scale between groups, suggesting that the basic sensory registration of body signals is unaffected.
How did the bodily awareness of depressed individuals compare to those with somatoform disorders?
Both groups showed low trust in their bodies and poor self-regulation, but depressed individuals scored uniquely lower on body listening and attention regulation.
What specific cognitive aspects of body perception are altered in people with somatoform issues?
They struggle with ignoring physical pain, worry more about minor discomfort, find it harder to regulate their distress, and view their body as less safe and trustworthy.
Can a person's inner body awareness be improved through clinical therapy?
Yes, the researchers suggest that clinical interventions like mindfulness training or cognitive reappraisal could help patients build trust and reduce catastrophic expectations about physical sensations.
