Do body-related sensations make feel us better? Subjective well-being is associated only with the subjective aspect of interoception.

According to the proposition of several theoretical accounts, the perception of the bodily cues, interoceptive accuracy and interoceptive sensibility, has a significant positive impact on subjective well-being. Others assume a negative association; however, empirical evidence is scarce. In this study, 142 young adults completed questionnaires assessing subjective well-being, interoceptive sensibility, and subjective somatic symptoms and participated in measurements of proprioceptive accuracy (reproduction of the angle of the elbow joint), gastric sensitivity (water load test), and heartbeat tracking ability (Schandry task). Subjective well-being showed weak to medium positive associations with interoceptive sensibility and weak negative associations with symptom reports. No associations with measures of interoceptive accuracy were found. Gastric sensitivity as opposed to heartbeat perception and proprioceptive accuracy moderated the association between interoceptive sensibility and well-being. Thus, subjective well-being is associated only with the self-reported (perceived) aspect of interoception but not related to the sensory measures of interoceptive accuracy.
