Highly Sensitive Person (HSP) scales are developed to assess Japanese individuals with sensory-processing sensitivity (SPS; Aron & Aron, 1997). Takahashi's (2015) and Funahashi's (2012) scale is developed for adults, whereas Iimura's (2015) scale assesses junior high school students. This study focuses on these HSP scales and provides two topics based on the relevant statistical perspectives. The objectives of this study are twofold:(1) To examine the statistical characteristics of HSP scales in Japan using item response theory and cluster analysis profiling Japanese HSPs types of SPS.(2) To determine the accuracy of HSP scales in Japan for assessing SPS traits. This study discusses the statistical validity of the Japanese version of the HSP scales based on the relation among introversion, neuroticism, and the behavioral inhibition system.
