Factor Analysis of the Individual with Highly Sensitive Processing Scale: The Association of Sensory Processing Sensitivity

The aim of the present study was to examine the psychometric properties of individuals with Highly Sensitive Processing Sensitivity Scale (HSPSS) in the cultural pattern of Iranian Society in relation to psychopathological characteristics. 372 male undergraduate students were selected using stratified random sampling and evaluated using the Highly Sensory Processing Person (HSPPS) Scale, Beck Depression Inventory (BDI) and Spielberger's State-Trait Anxiety Inventory (STAI). Data were analyzed using factor analysis, correlation test and multiple regression. The results support a three-component structure of Ease of Excitation (EOE), Low Sensitivity Threshold (LST) and Enrichment by Aesthetic and Sensory Sensitivity (EASS). This study showed that sensory processing sensitivity is related to psychopathological measures. Also, EOE and LST were selectively associated with anxiety and depression. Aesthetic and Sensory Sensitivity are indirectly associated with anxiety and depression, which indicates its protective role.
