Conceptual ambiguities and measurement issues in sensory processing sensitivity

The aim of the article is (1) to critically discuss Sensory Processing Sensitivity (SPS) in light of personality theories and (2) to examine the validity of the only available measure of SPS, the Highly Sensitive Person Scale (HSPS). Study 1 (N = 289) examines the relations of the HSPS with facets of the Big Five. In Study 2 (N = 226), the HSPS' relation to emotion recognition ability is estimated after controlling for the Big Five. In contrast to previous studies, these relationships are estimated at the level of latent variables. Our data suggest that SPS highly overlaps with established personality traits, and its relation with emotion recognition ability can be fully explained by Neuroticism and Openness to Experience.
