Application of the Highly Sensitive Person Scale (HSPS) in the Lithuanian adult population: Psychometric characteristics and associations with psychological factors

Abstract

Sensory processing sensitivity (SPS) is a personality trait characterized by heightened responsiveness to environmental stimuli, often linked to introversion and emotional reactivity. This study evaluated the factorial structure of the Lithuanian version of the Highly Sensitive Person Scale (HSPS) and its associations with anxiety, depression, and personality traits. A cross-sectional survey of 1130 Lithuanian employees was conducted. Exploratory and confirmatory factor analyses supported a three-factor model: Low Sensory Threshold and Withdrawal, Ease of Excitation, and Aesthetic Sensitivity. HSPS scores were negatively correlated with Extraversion and Emotional Stability and positively associated with anxiety and depression symptoms. The Lithuanian HSPS is a reliable and valid instrument for assessing SPS in adults.
