Constitutional differences in the control of the bodily state are thought to generate a vulnerability to psychological symptoms. Autonomic nervous system dysfunctions have been associated with anxiety, depression, and post-traumatic stress. Though interoception may be a transdiagnostic mechanism promoting the improvement of clinical symptomatology, few psychometrically sound, symptom-independent, self-report measures, informed by brain\u2013body circuits, are available for research and clinical use. We validated the Italian version of the body perception questionnaire (BPQ)\u2014short form and found that response categories could be collapsed from five to three and that the questionnaire retained a three-factor structure with items reduced from 46 to 22 (BPQ-22). The first factor was loaded by body awareness items; the second factor comprised some items from the body awareness scale and some from the subdiaphragmatic reactivity scale (but all related to bloating and digestive issues), and the third factor by supradiaphragmatic reactivity items. The BPQ-22 had sound psychometric properties, good convergent and discriminant validity and test\u2013retest reliability and could be used in clinical and research settings in which the body perception assessment is of interest. Psychometric findings in light of the polyvagal theory are discussed.<\/jats:p>","DOI":"10.3390\/ijerph18073835","type":"journal-article","created":{"date-parts":[[2021,4,6]],"date-time":"2021-04-06T10:34:12Z","timestamp":1617705252000},"page":"3835","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":45,"title":["Item Reduction, Psychometric and Biometric Properties of the Italian Version of the Body Perception Questionnaire\u2014Short Form (BPQ-SF): The BPQ-22"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7163-9627","authenticated-orcid":false,"given":"Andrea","family":"Poli","sequence":"first","affiliation":[{"name":"Department of Surgical, Medical and Molecular Pathology and of Critical Care Medicine, University of Pisa, 56126 Pisa, Italy"},{"name":"Department of Clinical and Experimental Medicine, University of Pisa, 56126 Pisa, Italy"},{"name":"Verdi Clinical Center, 59100 Prato, Italy"},{"name":"Florence Cognitive School, 50144 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7728-3705","authenticated-orcid":false,"given":"Angelo Giovanni Icro","family":"Maremmani","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, North-Western Tuscany Region NHS Local Health Unit, Versilia Zone, 55049 Viareggio, Italy"},{"name":"Association for the Application of Neuroscientific Knowledge to Social Aims (AU-CNS), 55045 Pietrasanta, Italy"},{"name":"G.
