The interoceptive sensibility in middle childhood: the Italian validation of the Self-Awareness Questionnaire.

Interoception refers to the processing of internal bodily states and plays a critical role in motivational processes and behaviours. Instruments for assessing its subjective components (i.e., interoceptive sensibility) during childhood are crucially needed. Thus, in this study, we adapted and evaluated the psychometric properties of the Self-Awareness Questionnaire (SAQ) in a sample of Italian children. The SAQ language was revised, and 239 children, ranging in age from 7 to 13 years, completed the adapted questionnaire (SAQ-C). A two-factor solution (visceral and somatosensorial domains) with 24 items showed the best fit of the data. The reliability was good. Convergent validity was fair, and the results indicated good discriminant validity. Moreover, correlational and regression analyses showed that interoceptive sensibility, particularly that associated with visceral sensations, increased with age. Current findings provide preliminary evidence that the SAQ-C may be a reliable and valid tool for assessing interoceptive sensibility in middle childhood. [ABSTRACT FROM AUTHOR]
