Its goals are 3-fold: extend category options; characterize how the new scale variant tracks with the Mini-Mental State Examination; and present a series of associative findings. Secondary analysis of data from 3733 older adults from 8 countries was completed. Examination of scale dimensions using older and new items was completed using a forward-entry stepwise regression. The revised scale was validated by examining the scale\u2019s distribution with a self-reported dementia diagnosis, functional problems, living status, and distress measures. Cognitive Performance Scale 2 extends the measurement metric from a range of 0 to 6 for the original CPS, to 0 to 8. Relating CPS2 to other measures of function, living status, and distress showed that changes in these external measures correspond with increased challenges in cognitive performance. Cognitive Performance Scale 2 enables repeated assessments, sensitive to detect changes particularly in early levels of cognitive decline.<\/jats:p>","DOI":"10.1177\/0891988715598231","type":"journal-article","created":{"date-parts":[[2015,8,6]],"date-time":"2015-08-06T21:30:23Z","timestamp":1438896623000},"page":"47-55","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":62,"title":["Updating the Cognitive Performance Scale"],"prefix":"10.1177","volume":"29","author":[{"given":"John N.","family":"Morris","sequence":"first","affiliation":[{"name":"Hebrew SeniorLife, Institute for Aging Research, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth P.","family":"Howard","sequence":"additional","affiliation":[{"name":"School of Nursing, Northeastern University, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Knight","family":"Steel","sequence":"additional","affiliation":[{"name":"Hackensack University Medical Center, Hackensack, NJ, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Perlman","sequence":"additional","affiliation":[{"name":"School of Public Health and Health System, University of Waterloo, Waterloo, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brant E.","family":"Fries","sequence":"additional","affiliation":[{"name":"Institute of Gerontology and Geriatric Research, Education and Clinical Center, Ann Arbor VA Healthcare Center, University of Michigan, Ann Arbor, MI, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vjenka","family":"Garms-Homolov\u00e1","sequence":"additional","affiliation":[{"name":"Hochschule fur Technik und Wirtschatt, Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Claude","family":"Henrard","sequence":"additional","affiliation":[{"name":"Versailles-Saint Quentin, En Yvelines (UVSQ) University, Laboratoire Sant\u00e9, Environment Vieillissement, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John P.","family":"Hirdes","sequence":"additional","affiliation":[{"name":"Ontario Home Care Research and Knowledge Exchange Chair, University of Waterloo, Waterloo, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gunnar","family":"Ljunggren","sequence":"additional","affiliation":[{"name":"Department of Learning, Informatics, Management and Ethics, Karolinska Institutet, Stockholm, Sweden"},{"name":"Public Healthcare Services Committee Administration, Stockholm County Council, Stockholm, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Len","family":"Gray","sequence":"additional","affiliation":[{"name":"Centre for Research in Geriatric Medicine, Centre for Online Health, The University of Queensland, Brisbane, Queensland, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katarzyna","family":"Szczerbi\u0144ska","sequence":"additional","affiliation":[{"name":"Unit for Research on Aging Society, Department of Sociology of Medicine, at The Chair of Epidemiology and Preventive Medicine, Medical Faculty, Jagiellonian University Medical College, Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2015,8,6]]},"reference":[{"key":"bibr1-0891988715598231","doi-asserted-by":"publisher","DOI":"10.1016\/j.jalz.2010.11.007"},{"key":"bibr2-0891988715598231","doi-asserted-by":"publisher","DOI":"10.1017\/S135561770505109X"},{"key":"bibr3-0891988715598231","doi-asserted-by":"publisher","DOI":"10.1038\/nature10243"},{"key":"bibr4-0891988715598231","doi-asserted-by":"publisher","DOI":"10.1016\/j.jalz.2011.03.008"},{"key":"bibr5-0891988715598231","doi-asserted-by":"publisher","DOI":"10.1176\/appi.ajp.2010.09050692"},{"key":"bibr6-0891988715598231","doi-asserted-by":"publisher","DOI":"10.1080\/09602011.2010.543867"},{"key":"bibr7-0891988715598231","doi-asserted-by":"publisher","DOI":"10.1016\/j.jalz.2011.05.605"},{"key":"bibr8-0891988715598231","doi-asserted-by":"publisher","DOI":"10.1159\/000115848"},{"key":"bibr9-0891988715598231","unstructured":"Bushnik T.
