Somatosensory amplification in hypochondriasis and panic disorder

Abstract

The aim of this study is to explore the differences and similarities of Somatic Amplification (SA) in both panic and hypochondriasis disorders. An additional objective is to validate the Somatosensory Amplification Scale (SSAS) for use in our cultural context. For these purposes, 34 patients (17 with hypochondriasis and 17 with panic disorder; DSM-III-R criteria) completed the following questionnaires: SSAS, State–Trait Anxiety Inventory, Beck Depression Inventory, MMPI Hypochondriasis Scale, Illness Attitude Scales and Illness Behaviour Questionnaire. The SSAS showed a satisfactory internal consistency (Cronbach's α=0·83), and revealed two components: ‘Internal Stimulus Amplification’ and ‘External Stimulus Amplification’. No significant differences were observed between patients with hypochondriasis and patients with panic disorder on the SSAS. In both groups the SSAS was associated with health concerns (Illness Attitude Scales). The best predictors of SA were Bodily Preoccupation (Illness Attitude Scales) in the hypochondriasis group, and Depression in the panic disorder group. Copyright © 1999 John Wiley & Sons, Ltd.
