Research has pointed to two profiles of persons with fibromyalgia according to differences in functionality, thus distinguishing between functional and dysfunctional patients. The role of psychological factors underlying such clusters is unclear. This study aims to explore the contribution of pain beliefs and coping on fibromyalgia clustering. Methods. A cluster analysis was performed to classify 238 women with fibromyalgia using the Fibromyalgia Impact Questionnaire and the Beck Depression Inventory as clustering variables. Cluster differences in physical functioning, depression, pain beliefs, coping, and age were then calculated (Student\u2019s t-test). Finally, a binary logistic regression was conducted to study the unique contribution of age, beliefs, and coping on cluster classification. Results. Two clusters were revealed. Cluster 1 had a poor adaptation to fibromyalgia regarding physical functioning and depression. They generally embraced less adaptive beliefs (i.e., disability, harm, emotion, and requests) and coping strategies (i.e., guarding, resting, and asking for assistance). Cluster 2 showed a better adaptation to fibromyalgia and adopted more favorable beliefs (i.e., control) and coping strategies (i.e., exercise and task persistence). Cluster differences in age were significant but small. The backward binary logistic regression suggested a final model with six predictors (guarding, task persistence, harm, emotion, solicitude, and age) that explained 31% of the variance of group membership. Discussion. These results suggest that only a subset of psychological variables uniquely and independently contribute to functional\/dysfunctional group membership. The results support the need to address psychological components in the management of fibromyalgia and point to a subset of preferred target beliefs and coping strategies.<\/jats:p>","DOI":"10.1155\/2022\/1066192","type":"journal-article","created":{"date-parts":[[2022,4,14]],"date-time":"2022-04-14T20:50:08Z","timestamp":1649969408000},"page":"1-10","source":"Crossref","is-referenced-by-count":10,"title":["Coping and Beliefs as Predictors of Functioning and Psychological Adjustment in Fibromyalgia Subgroups"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7472-1263","authenticated-orcid":true,"given":"Laura","family":"Rubio Fidel","sequence":"first","affiliation":[{"name":"Consorcio Hospitalario Provincial de Castell\u00f3, Castell\u00f3 de la Plana, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9250-8714","authenticated-orcid":true,"given":"Azucena","family":"Garc\u00eda-Palacios","sequence":"additional","affiliation":[{"name":"Department of Basic Psychology, Clinic and Psychobiology, Universitat Jaume I, Castell\u00f3 de la Plana, Spain"},{"name":"CIBEROBN Physiopathology of Obesity and Nutrition, Instituto de Salud Carlos III, 28029 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6987-6607","authenticated-orcid":true,"given":"Roc\u00edo","family":"Herrero","sequence":"additional","affiliation":[{"name":"CIBEROBN Physiopathology of Obesity and Nutrition, Instituto de Salud Carlos III, 28029 Madrid, Spain"},{"name":"Polibienestar Research Institute, University of Valencia, Valencia 46022, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1957-9353","authenticated-orcid":true,"given":"Guadalupe","family":"Molinari","sequence":"additional","affiliation":[{"name":"CIBEROBN Physiopathology of Obesity and Nutrition, Instituto de Salud Carlos III, 28029 Madrid, Spain"},{"name":"Valencian International University-VIU, Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2655-1017","authenticated-orcid":true,"given":"Carlos","family":"Suso-Ribera","sequence":"additional","affiliation":[{"name":"Department of Basic Psychology, Clinic and Psychobiology, Universitat Jaume I, Castell\u00f3 de la Plana, Spain"},{"name":"CIBEROBN Physiopathology of Obesity and Nutrition, Instituto de Salud Carlos III, 28029 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1002\/acr.20140"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.semarthrit.2016.08.012"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0074873"},{"key":"4","doi-asserted-by":"crossref","first-page":"2015","DOI":"10.1093\/rheumatology\/kex302","article-title":"Adaptation profiles comprising objective and subjective measures in fibromyalgia: the al-\u00c1ndalus project","volume":"56","author":"F.
