Somatoform Disorders

Evidence-informed definition Updated September 3, 2026 How to cite this entry

Somatoform disorders refer to a group of psychological conditions in which individuals experience significant physical symptoms, health concerns, or bodily distress that are associated with psychological factors and cannot be fully explained by another medical condition.

Somatoform disorders are a former diagnostic category characterized by physical symptoms, bodily concerns, or health-related distress associated with significant psychological distress or impairment. The term was used in earlier diagnostic classifications, including DSM-IV-TR, and was replaced in DSM-5 by Somatic Symptom and Related Disorders, which focuses on significant somatic symptoms and/or illness anxiety associated with distress and impairment. (American Psychiatric Association, 2022).
