The average PCS total score was 15.1 (11.6) points. For all 13 items, the estimates of difficulty parameter indicated a shift towards higher PCS scores. This was also seen in item characteristic curves and item information function. Respectively, the entire composite score showed the same shift towards higher PCS scores. The discrimination of PCS was excellent 1.98 (95% CI 1.89\u20132.07).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Overall, the psychometric properties of the PCS were found to be sufficiently good to recommend this scale for clinical use in CTS. The PCS is well able to distinguish between people with different levels of pain catastrophizing, even if performing better in elevated levels of catastrophizing. Also, the respondents may have a slight tendency to underestimate the severity of their catastrophizing when responding to the PCS. The results may be of interest to both clinicians and researchers in planning and implementing conservative or operative treatment for CTS, setting rehabilitation goals, and evaluating treatment or rehabilitation outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1515\/sjpain-2024-0079","type":"journal-article","created":{"date-parts":[[2025,5,14]],"date-time":"2025-05-14T11:22:57Z","timestamp":1747221777000},"source":"Crossref","is-referenced-by-count":2,"title":["Properties of pain catastrophizing scale amongst patients with carpal tunnel syndrome \u2013 Item response theory analysis"],"prefix":"10.1515","volume":"25","author":[{"given":"Mikhail","family":"Saltychev","sequence":"first","affiliation":[{"name":"Department of Physical and Rehabilitation Medicine, Turku University Hospital and University of Turku , PO Box 52, FI-20521 , Turku , Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annika","family":"Miikkulainen","sequence":"additional","affiliation":[{"name":"Department of Physical and Rehabilitation Medicine, Turku University Hospital and University of Turku , PO Box 52, FI-20521 , Turku , Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanna-Stiina","family":"Taskinen","sequence":"additional","affiliation":[{"name":"Department of Hand Surgery, Turku University Hospital and University of Turku , Turku , Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"374","published-online":{"date-parts":[[2025,5,7]]},"reference":[{"key":"2025120909552330509_j_sjpain-2024-0079_ref_001","doi-asserted-by":"crossref","unstructured":"Daliri BOM, Azhari A, Khaki S, Hajebi Khaniki S, Moradi A.
