What type of disorder arises from psychological factors without a physical basis?

The correct answer is centered around the concept that somatoform disorders are primarily characterized by the manifestation of psychological distress as physical symptoms, despite the absence of any identifiable physical illness that can explain these symptoms. Individuals with this type of disorder may experience symptoms such as pain, fatigue, or gastrointestinal issues, but medical evaluations typically reveal no physiological issues. The psychological factors at play are significant, suggesting that the symptoms stem from emotional or mental processes rather than from any organic disease.

This makes somatoform disorders distinctly different from anxiety disorders, personality disorders, and schizophrenia, all of which can have a more identifiable psychological or behavioral basis and may also involve elements that could be linked to biological or environmental influences. In contrast, the primary feature of somatoform disorders is the disconnection between the psychological state and the physical manifestations experienced by the individual, reinforcing that the symptoms arise fundamentally from psychological factors.
