Abstract

Interoception, the ability to detect internal bodily signals, is vital for an individual's well-being and is increasingly connected to mental health disorders. Research investigating relationships between individual differences in interoception and personality types is limited, and mixed results are reported across a variety of interoceptive tasks, measures, and conceptualisations. Guided by biological theories, this study contributed further to the understanding of the relationship between interoception and personality by utilising two interoceptive measures. A sample of adults (N = 114) completed three questionnaires online questionnaire, two assessing interoceptive sensibility ( Body Perception Questionnaire, BPQ; and the Multidimensional Assessment of Interoceptive Awareness, MAIA) and one that assessed personality ( Eysenck Personality Inventory, EPI). Multiple regression and correlational analyses showed no significant relationship between interoceptive sensibility and introversion, whereas a predictive relationship was demonstrated between interoceptive sensibility and neuroticism. Furthermore, the BPQ and subscales of the MAIA predicted neuroticism in different directions suggesting the two measures assess different constructs and thus strengthened support for a multidimensional consideration of interoception. The results have clinical implications, including the targeting of contemplative training approaches for individuals demonstrating high interoceptive sensibility and neurotic traits to improve the mental well-being of healthy individuals and clinical populations.
