Somatosensory amplification absorption contribute to electrosensitivity.

ABSTRACT

BACKGROUND AND PURPOSE: Two trait-like characteristics, somatosensory amplification and absorption, have been associated with symptom reports and idiopathic environmental intolerances in past research. Purpose - As the two constructs are not connected with each other, their independent contribution to symptom reports and electromagnetic hypersensitivity, as well as their interaction can be expected. METHODS: On-line questionnaire. Patients - 506 college students completed an on-line questionnaire assessing absorption, somatosensory amplification, negative affect, somatic symptoms, and electromagnetic hypersensitivity. RESULTS: Somatosensory amplification (ß = 0.170, p < 0.001) and absorption (ß = 0.128, p < 0.001) independently contributed to somatic symptoms after controlling for gender and negative affect (R2 = 0.347, p < 0.001). Similarly, somatosensory amplification (OR = 1.082, p < 0.05) and absorption (OR = 1.079, p < 0.01) independently contributed to electromagnetic hypersensitivity after controlling for somatic symptoms, gender, and negative affect (Nagelkerke R2 = 0.134, p < 0.001). However, no interaction effects were found. CONCLUSION: Somatosensory amplification and absorption independently contribute to symptom reports and electromagnetic hypersensitivity. Conclusion - The findings suggest that psychological mechanisms underlying symptom reports and electromagnetic hypersensitivity might be heterogeneous.
