In the realm of abnormal psychology, a distinction exists among various somatic symptom and related disorders, which encompass a range of conditions that impact the individual’s experience of physical symptoms. Focus on these disorders can illuminate the complexities involved, such as how the mind and body interact in distress, which can lead even well-trained clinicians to occasionally misdiagnose. Imagine a scenario where an individual presents symptoms resembling irritable bowel syndrome (IBS), citing severe discomfort, changes in bowel habits, and anxiety about the possibility of having a serious medical condition. However, a thorough evaluation reveals no physiological basis for these symptoms. Under such complex circumstances, which classification under the DSM-5 appropriately describes this scenario?
