Aron and Aron (1997) developed the Highly Sensitive Person Scale (HSPS) to measure individual differences in sensory-processing sensitivity (SPS). The purpose of the present study was to examine further the psychometric properties of the HSPS, and its association with the behavioural inhibition system (BIS) and behavioural activation system (BAS) (Carver & White, 1994), and the Big Five (Costa & McCrae, 1992). Results demonstrate that the HSPS is a valid and reliable measure of the construct of SPS. However, in contrast to Aron and Aron's finding that the scale is unidimensional, the current results support a three-component structure consisting of Aesthetic Sensitivity (AES), Low Sensory Threshold (LST), and Ease of Excitation (EOE). BIS activity was especially associated with the component of EOE. In addition, the components had different patterns of association with the Big Five. More specifically, AES showed the strongest relation with Openness to Experience, while LST and EOE were found to be most closely associated with Neuroticism. (c) 2005 Elsevier Ltd.
