Dissociations between self-reported interoceptive accuracy and attention: Evidence from the Interoceptive Attention Scale

Abstract

Models of interoception highlight the importance of considering participants' beliefs regarding their interoceptive ability. Research focusing on such beliefs suggests a dissociation between self-reported interoceptive accuracy and attention. However, it remains unclear whether such dissociations are driven by differences in the sensations rated across these questionnaires, or a genuine dissociation between different facets of self-reported interoception. Here we examined the relationship between self-report measures of interoceptive accuracy and attention using a novel measure- the Interoceptive Attention Scale- designed to match the interoceptive sensations included in an existing questionnaire measure of interoceptive accuracy. In addition, we examined whether the interpretation of questionnaire measures of interoception altered associations across measures. Results support the proposed distinction between self-reported interoceptive attention and accuracy and highlight the importance of considering the interpretation of questionnaire measures of interoception. The implications of these findings for theory, future research, and interpretation of existing research are discussed.
