Method: The MEDLINE, Embase, PubMed, and Google Scholar databases were searched from their inception to September 2019. We included prospective measurement studies that reported on the psychometric properties (reliability, validity, responsiveness) of the PSFS in people with low back pain or pathology. We followed the COnsensus-based Standards for the selection of health Measurement INstruments 2018 guideline for systematic reviews. We performed both quantitative and qualitative syntheses in which the results were summarized on the basis of the reported measurement properties and study quality. Results: Ten eligible studies were included. The pooled PSFS reliability measure was excellent (intra-class correlation coefficient\u00a0=\u00a00.89; 95% CI: 0.75, 0.95). Validity measures displayed correlations that ranged from \u22120.47 to 0.69 when compared with other patient-reported outcome measures (PROMs) or other tests. Eight studies had assessed the responsiveness of the PSFS. Effect sizes reported were large (\u2265\u00a00.91). Conclusions: The PSFS is a reliable, valid, and responsive PROM for patients with low back pain or pathology. <\/jats:p>","DOI":"10.3138\/ptc-2020-0042","type":"journal-article","created":{"date-parts":[[2021,6,9]],"date-time":"2021-06-09T23:45:37Z","timestamp":1623282337000},"page":"6-14","source":"Crossref","is-referenced-by-count":14,"title":["Psychometric Properties of the Patient-Specific Functional Scale in Patients with Low Back Pathology: A Systematic Review and Meta-Analysis"],"prefix":"10.3138","volume":"74","author":[{"given":"Goris","family":"Nazari","sequence":"first","affiliation":[{"name":"School of Physical Therapy, Faculty of Health Sciences, Western University, London, Ontario, Canada"},{"name":"Collaborative Program in Musculoskeletal Health Research, Bone and Joint Institute, Western University, London, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pavlos","family":"Bobos","sequence":"additional","affiliation":[{"name":"School of Physical Therapy, Faculty of Health Sciences, Western University, London, Ontario, Canada"},{"name":"Collaborative Program in Musculoskeletal Health Research, Bone and Joint Institute, Western University, London, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steve","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Rehabilitation Science, McMaster University, Hamilton, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephanie","family":"Reischl","sequence":"additional","affiliation":[{"name":"School of Physical Therapy, Faculty of Health Sciences, Western University, London, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pedro H.","family":"Almeida","sequence":"additional","affiliation":[{"name":"School of Physical Therapy, Faculty of Health Sciences, Western University, London, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joy C.","family":"MacDermid","sequence":"additional","affiliation":[{"name":"School of Physical Therapy, Faculty of Health Sciences, Western University, London, Ontario, Canada"},{"name":"Collaborative Program in Musculoskeletal Health Research, Bone and Joint Institute, Western University, London, Ontario, Canada"},{"name":"Roth McFarlane Hand and Upper Limb Centre, St. Joseph\u2019s Hospital, London, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1696","reference":[{"key":"r1","volume-title":"Injuries in Canada: insights from the Canadian Community Health Survey","author":"Billette J","year":"2011"},{"key":"r2","volume-title":"Health measurement scales: a practical guide to their development and use","author":"Streiner DL","year":"1995","edition":"2"},{"key":"r3","doi-asserted-by":"crossref","unstructured":"Nazari G, Bobos P, Lu S, et al.
