Abstract
Sensory Processing Sensitivity (SPS) is a genetically-determined trait that allows people to notice external and internal subtleties in sensory stimuli easily. This feature provides certain advantages to those who possess it, such as, greater empathy, artistic tastes or skills, also, this people can get greater benefit in circumstances with little exposure to sensory input. However, an unfavorable feature of the trait is an increased vulnerability to development psychopathology. In Mexico there is not an instrument to assess the presence of the SPS, thus, the purpose of this research was to analyze the psychometric properties of the Highly Sensitive Person Scale (HSP Scale) in Mexican population. The results showed that the adaptation of HSP Scale has adequate psychometric properties, so the essential contribution of this study is to provide a reliable and valid instrument that allows to discriminate the presence of the SPS.
