Abstract

Scholars and providers are coming to realize that one’s ability to notice and respond to internal body sensations contributes to an overall sense of wellbeing. Research has demonstrated a relationship between interoceptive awareness and anxiety, for example. Currently, however, tools for evaluating one’s interoception lack the conceptual foundation and clarity necessary to identify everyday behaviors that specifically reflect interoceptive awareness. Unlike existing interoceptive measures, the Sensory Profile Interoception scale is participation-based and grounded in Dunn’s Sensory Processing framework. In this study we investigated concurrent validity by correlating the SPI with the Adolescent/Adult Sensory Profile ; we investigated construct validity by correlating the SPI with the Perth Alexithymia Scale, the Body Awareness Scale, and the State-Trait Anxiety Inventory. Using the REDCAP online platform, 74 college-aged participants completed the measures. Using Spearman rank order correlations there were statistically significant relationships between the corresponding sensory pattern subscales on SPI and A/ASP. The PAS was only weakly related to the registration subscale of the SPI. The BAS had significant relationships with seeking and avoiding on the SPI. The STAI had significant relationships with sensitivity and registrations of the SPI. Taken together, these findings provide evidence of construct validity of the SPI to identify participation patterns associated with both high and low interoception. With the more precise information the SPI provides, professionals can design tailored interventions to support everyday life goals and researchers can study interoception within authentic activities.
