The Lithuanian Version of the Highly Sensitive Person Scale: Factor Structure and Latent Profiles in Emerging Adulthood

This study investigated the factor structure of the Lithuanian version of the Highly Sensitive Person (HSP) scale and identified sensory processing sensitivity (SPS) subgroups among emerging adults. A total of 651 participants aged 18–29 completed the instrument. Exploratory and confirmatory factor analyses supported a three-factor model—Ease of Excitation (EOE), Low Sensory Threshold (LST), and Aesthetic Sensitivity (AES)—consistent with previous cross-cultural findings. Latent profile analysis revealed four distinct SPS profiles: High-, Moderate-, Mild-, and Low-sensitivity. Overall, the findings provide evidence for the psychometric robustness of the Lithuanian HSP scale and point to the potential role of developmental context and gender in shaping SPS. This study contributes to cross-cultural validation initiatives and offers a foundation for future research and practical applications in psychological assessment and intervention with young adults.
