Can't suppress this feeling: automatic negative evaluations of somatosensory stimuli are related to the experience of somatic symptom distress.

Cognitive theories of medically unexplained ("somatoform") symptoms stress the importance of alterations in attention and memory processes. Accordingly, specific schemata are hypothesized to (mis-)guide the processing of somatosensory stimuli leading to the formation of symptom-like perceptions. The current study tested a possible association between altered automatic somatosensory evaluation processes and the tendency to experience somatoform symptoms in a nonclinical sample. In a first pilot study, a modified version of the affect misattribution procedure (AMP) by Payne, Cheng, Govorun, and Stewart (2005) with aversive and nonaversive tactile stimuli (nonpainful electric vs. vibration stimulus) was successfully tested in 40 college students. In a second study (n = 50), automatic evaluations following aversive tactile stimuli were found to be positively associated (r = .35) with somatic symptom distress (PHQ). Moreover, negative affectivity significantly moderated this association (i.e., people high on negative affectivity revealed the strongest associations between somatic symptom distress and negative automatic evaluations in the tactile AMP). The findings support cognitive theories of somatoform symptom formation. The tactile AMP is suggested as a promising paradigm to study automatic evaluations of body sensations in people with somatoform disorders and related clinical conditions.
