Abstract
Interoception is broadly defined as the processing of internal bodily states at multiple conscious and preconscious levels (Brewer et al., 2021). Because of the breadth of this construct, many measures exist to probe individual differences in interoception (Desmedt et al., 2023; Khalsa et al., 2018). Measures of interoception can be separated into different domains (e.g., cardiac, respiratory, gastric) and dimensions (e.g., accuracy, attention). Some of the most assessed domains of interoception, and associated measures, are reviewed below. We focus on interoceptive accuracy, as well as self-reported, implicit and neural measures of interoception, however, it should be noted that there are many other dimensions (Khalsa et al., 2018). Specific considerations for the measurement of stress alongside interoception are provided.
