Relationships between Occupant Personality and the Sick Building Syndrome Explored

Abstract

Increasing evidence shows that certain personality traits, such as negative affectivity (trait NA), are strongly associated with the reporting of symptoms. The role of personality in sick building syndrome (SBS) symptom reporting is therefore explored with the aid of a questionnaire completed by occupants living in apartments with indoor climate problems. A good fit to empirical data was obtained for a path model in which somatization intervenes between a general psychological factor (predominated by trait NA) and SBS. Occupants with "normal" and "aberrant" NA profiles were classified by cluster analysis and further divided according to frequency of symptoms. For occupants with 5 or more SBS symptoms, those with "aberrant" NA profiles have very similar SBS symptom profiles to those with "normal" NA profiles. This indicates that an occupant's trait NA score cannot be used for predicting his or her SBS symptom profile or frequency of SBS symptoms. An unexpected finding was that the occupants with "aberrant" NA profiles also perceived factors in the indoor (air) environment as less adverse than the 5 or more symptom reporting occupants with "normal" NA profile. Pennebaker and Brittingham's competition of external and internal cues model may explain the results for the occupants with "aberrant" NA profiles, however, our empirical data indicate that, unexpectedly, these occupants may not over-report SBS symptoms but rather under-report adverse environmental perceptions.
