The significance of the psychosocial work environment for the prevalen
ce of symptoms compatible with the ''sick building syndrome'' (SBS) wa
s studied in a case-referent study including 464 office workers, half
of whom had symptoms of SBS. A questionnaire was distributed to all su
bjects, and representatives of the organisations concerned were interv
iewed. The aim of the study was to investigate the importance of psych
osocial and organisational factors in explaining the prevalence of SBS
symptoms among office workers. The results showed that psychosocial w
ork characteristics, such as workload and job satisfaction, as well as
worry and reorganisation are factors that have a significant impact o
n the risk of developing the symptoms of SBS.
