Psychological factors are known to contribute to perceived (i.e., subjective) physical functioning. However, physical function is a multidimensional concept encompassing both subjective and objective functioning. The contribution of psychological factors to performance-based (i.e., objective) functioning is unclear. This study aims to investigate the contribution of pain catastrophizing and pain acceptance to both self-reported and performance-based physical functioning. In this cross-sectional study, 160 participants completed self-report measures of pain catastrophizing, pain acceptance, and pain severity. A self-report measure and a performance-based test were used to assess physical functioning. Higher pain catastrophizing and lower pain acceptance were associated with poorer physical functioning at both self-reported and performance-based levels. Our results are consistent with previous evidence on the association between pain catastrophizing and pain acceptance with self-reported physical functioning. This study contributes to the current literature by providing novel insights into the role of psychological factors in performance-based physical functioning. Multidisciplinary interventions that address pain catastrophizing and pain acceptance are recommended and might be effective to improve both perceived and performance-based functioning in women with FM and obesity.<\/jats:p>","DOI":"10.3390\/jpm11080810","type":"journal-article","created":{"date-parts":[[2021,8,20]],"date-time":"2021-08-20T08:44:45Z","timestamp":1629449085000},"page":"810","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["The Role of Pain Catastrophizing and Pain Acceptance in Performance-Based and Self-Reported Physical Functioning in Individuals with Fibromyalgia and Obesity"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8711-5975","authenticated-orcid":false,"given":"Giorgia","family":"Varallo","sequence":"first","affiliation":[{"name":"Psychology Research Laboratory, Istituto Auxologico Italiano IRCCS, San Giuseppe Hospital, 28824 Verbania, Italy"},{"name":"Department of Psychology, Catholic University of Milan, 20123 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Federica","family":"Scarpina","sequence":"additional","affiliation":[{"name":"\u201cRita Levi Montalcini\u201d Department of Neurosciences, University of Turin, 10124 Turin, Italy"},{"name":"Unit of Neurology and Neurorehabilitation, Istituto Auxologico Italiano IRCCS, San Giuseppe Hospital, 28824 Verbania, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5767-8785","authenticated-orcid":false,"given":"Emanuele Maria","family":"Giusti","sequence":"additional","affiliation":[{"name":"Psychology Research Laboratory, Istituto Auxologico Italiano IRCCS, San Giuseppe Hospital, 28824 Verbania, Italy"},{"name":"Department of Psychology, Catholic University of Milan, 20123 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2655-1017","authenticated-orcid":false,"given":"Carlos","family":"Suso-Ribera","sequence":"additional","affiliation":[{"name":"Department of Basic and Clinical Psychology and Psychobiology, Jaume I University, 12071 Castellon de la Plana, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"Cattivelli","sequence":"additional","affiliation":[{"name":"Psychology Research Laboratory, Istituto Auxologico Italiano IRCCS, San Giuseppe Hospital, 28824 Verbania, Italy"},{"name":"Department of Psychology, Catholic University of Milan, 20123 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Guerrini Usubini","sequence":"additional","affiliation":[{"name":"Psychology Research Laboratory, Istituto Auxologico Italiano IRCCS, San Giuseppe Hospital, 28824 Verbania, Italy"},{"name":"Department of Psychology, Catholic University of Milan, 20123 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3719-8789","authenticated-orcid":false,"given":"Paolo","family":"Capodaglio","sequence":"additional","affiliation":[{"name":"Orthopaedic Rehabilitation Unit and Research Laboratory in Biomechanics and Rehabilitation, Istituto Auxologico Italiano IRCCS, San Giuseppe Hospital, 28824 Verbania, Italy"},{"name":"Department of Surgical Sciences, Physical and Rehabilitation Medicine, University of Turin, 10121 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gianluca","family":"Castelnuovo","sequence":"additional","affiliation":[{"name":"Psychology Research Laboratory, Istituto Auxologico Italiano IRCCS, San Giuseppe Hospital, 28824 Verbania, Italy"},{"name":"Department of Psychology, Catholic University of Milan, 20123 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"319","DOI":"10.1016\/j.semarthrit.2016.08.012","article-title":"2016 Revisions to the 2010\/2011 fibromyalgia diagnostic criteria","volume":"46","author":"Wolfe","year":"2016","journal-title":"Semin.
