Normative data of the Chemical Sensitivity Scale

Authors: Nordin S, Bende M, Millqvist E

Journal: J Environ Psychol 2004;77:399-403

The Chemical Sensitivity Scale (CSS) is used to quantify affective reactions to and behavioral disruptions by odorous/pungent substances in the environment, and has good test-retest reliability, good internal consistency, satisfying predictive and concurrent validity, and two major dimensions. However, to enable identification of hypersensitive individuals, the objective of the present study was to collect normative data for reference, by means of a population-based study. From the sample of the Skövde general population-based study, a sub-sample of 693 individuals was drawn, stratified in proportion to age and gender. In total, 596 individuals (86%), aged 20-88 years, agreed to participate by responding to the CSS. The results show that the CSS generates approximately normal distributions, irrespective of age group and gender. Furthermore, CSS scores were found to be higher in elderly than in young and middle aged adults, and higher in women than in men. Obtained standard deviations and confidence intervals may be used for reference, such as for criteria for identifying individuals with environmental hypersensitivity to odorous/pungent substances
