The somatosensory amplification scale and its relationship to hypochondriasis. Barsky AJ1, Wyshak G, Klerman GL.
It is a common feature of hypochondriasis and is commonly found with fibromyalgia, major depressive disorder, some anxiety disorders, Asperger syndrome, and alexithymia. [1][2][3][4] One common clinical measure of SA is the Somatosensory Amplification Scale.
Data were collected on demographics; DSM-IV diagnoses; and measures of anxiety, depression, and alexithymia, assessed with the Toronto Alexithymia Scale (TAS-20), as well as somatic amplification, assessed with the Somatosensory Amplification Scale (SAS). Data analysis revealed low scores on the TAS-20 and SAS for the pain patients, compared with a control group without pain. In this sample, depression and anxiety were the primary determinants of alexithymia and somatic amplification, rather than pain.
To assess such patients objectively, the concept of somatosensory amplification may be useful. Somatosensory amplification refers to the tendency to experience a somatic sensation as intense, noxious, and disturbing. It may have a role in a variety of medical conditions characterized by somatic symptoms that are disproportionate to demonstrable organ pathology. It may also explain some of the variability in somatic symptomatology found among different patients with the same serious medical disorder. It has been assessed with a self-report questionnaire, the Somatosensory Amplification Scale.
The Somatosensory Amplification Scale (SSAS) is a self-evaluating scale for measuring amplification while somatizing. The developers of the scale demonstrated that the scale had sufficient internal consistency and test–retest reliability. 2 Barsky et al. 2 hypothesized that bodily sensations of hypochondriac patients are unduly disturbed, a self-report questionnaire would necessarily have to assess the respondent’s sensitivity to mild bodily discomforts but which are not typical symptoms of disease.
