Parkinson\u2019s Disease Cognitive Rating Scale (PD-CRS) is one of the recommended scales by the Movement Disorders Society Task Force for level 1 screening of dementia. However, its psychometric properties have not been studied in the Colombian population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cross-sectional study was conducted on 100 patients with Parkinson\u2019s disease diagnosed by a movement disorders neurologist. Patients were evaluated with PD-CRS and MoCA. Principal component analysis was conducted, and then confirmatory factor analysis was implemented through the maximum-likelihood method. Internal consistency was evaluated using Cronbach <jats:italic>\u03b1<\/jats:italic>. Convergent and divergent validity were also calculated and concurrent validity with the MoCA was assessed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>62% were males. Their median age was 68 years (IQR 57\u201374) and the median disease duration was 4 years (IQR 2\u20139). 77% were classified in early stages (Hoehn and Yahr stage \u2264\u20092), while the MDS-UPDRS part III score was 25 (IQR 15.5\u201338). In the principal component factor analysis, the pattern matrix unveiled a mnesic and a non-mnesic domain. Confirmatory factor analysis showed similar explanatory capacity (<jats:italic>\u03bb<\/jats:italic>\u2009\u2265\u20090.50) for items other than naming (<jats:italic>\u03bb<\/jats:italic>\u2009=\u20090.34). Cronbach\u2019s <jats:italic>\u03b1<\/jats:italic> for the full 9-items instrument was 0.74. MoCA and PD-CRS total scores were correlated (<jats:italic>\u03c1<\/jats:italic>\u2009=\u20090.71, <jats:italic>p<\/jats:italic>\u2009=\u20090.000). Assuming a cut-off score of 62 points, there is an agreement of 89% with the definition of dementia by MoCA for Colombia (<jats:italic>\u03ba<\/jats:italic>\u2009=\u20090.59; <jats:italic>p<\/jats:italic>\u2009=\u20090.000).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>PD-CRS has acceptable psychometric properties for the Colombian population and has significant correlation and agreement with a validated scale (MoCA).<\/jats:p><\/jats:sec>","DOI":"10.3389\/fpsyg.2022.1018176","type":"journal-article","created":{"date-parts":[[2022,12,1]],"date-time":"2022-12-01T19:31:06Z","timestamp":1669923066000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Psychometric properties and construct validity of the Parkinson\u2019s Disease-Cognitive Rating Scale (PD-CRS) in Colombia"],"prefix":"10.3389","volume":"13","author":[{"given":"Hugo Juan Camilo","family":"Clavijo-Moran","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniela","family":"\u00c1lvarez-Garc\u00eda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriel D.","family":"Pinilla-Monsalve","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beatriz","family":"Mu\u00f1oz-Ospina","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorge","family":"Orozco","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,12,1]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"193","DOI":"10.1023\/a:1015291021312","article-title":"Assessing health status and quality-of-life instruments: attributes and review criteria","volume":"11","author":"Aaronson","year":"2002","journal-title":"Qual.
