Illness attributed to the environment, particularly the Multiple Chemical Sensitivity (MCS), appears to become more common. The origin of environmental syndromes is unclear, the relevance of the high psychiatric (co-)morbidity is contentious. Analysis of psychometric data concerning the personality of 306 patients presenting to our university environmental clinic showed only few features that allow us to distinguish different ranges of complaints. Increased somatization, however, did become apparent. Differences in personality obvious when comparing patients with sypmtoms depending on exposure to multiple triggers and patients with other disorders attributed to the environment. Patients with the MCS syndrome additionally exhibited narcisstic-paranoid and schizotypal features, whereas patients with other illness attributed to the environment showed obsessive-compulsive and depressive characteristics. Further more, we found a clearly higher prevalence of psychotic, especially current delusional disorders, in MCS. However, psychiatric morbidity differed only slightly between patients with or without MCS.
