Objectives. A short version of the 21-item Chemical Sensitivity Scale (CSS), called the Chemical Sensitivity Scale for Sensory Hyperreactivity (CSS-SHR), was developed and evaluated for the quantifying of self-reported affective reactions to and behavioral disruptions in daily activities by odorous/pungent substances among patients with sensory hyperreactivity (SHR) for clinical and epidemiological studies. Methods. Twenty-two patients with clinically diagnosed SHR and 124 control participants responded to the CSS and to additional questions about chemical sensitivity for the evaluation of the CSS-SHR. Results. Eleven of the 21 items of the CSS were selected, on statistical grounds, to constitute the CSS-SHR, which was found to generate approximately normal distributions, have good test-retest reliability (r(xy)=0.87), satisfying internal consistency (r(alpha)=0.76-0.84) and predictive and concurrent validity, and to be uni-dimensional. The metric properties of the CSS-SHR were, despite its few items, comparable with those of the CSS. A proposed diagnostic cut-off score for SHR demonstrated a high correct classification rate (92%) for the CSS-SHR. Conclusions. The favorable metric properties of the CSS-SHR and its sensitivity/specificity suggests that it is useful for clinical diagnosis and epidemiological study of sensory hyperreactivity in combination with other diagnostic tools.
