Method: Mothers and teachers rated SCT, ADHD-IN, ADHD\u2013hyperactivity\/impulsivity (ADHD-HI), oppositional defiant disorder (ODD), anxiety, depression, academic impairment, social impairment, and peer rejection (teachers only) in 652 Chilean children (55% boys) aged 6 to 14 years. Results: For both mother and teacher ratings, the eight SCT symptoms and nine ADHD-IN symptoms showed substantial loadings on their respective factors (convergent validity) along with loadings close to zero on the alternative factor (discriminant validity). ADHD-IN showed a uniquely stronger relationship than SCT with ADHD-HI and ODD whereas SCT showed a uniquely stronger relationship than ADHD-IN with anxiety and depression. Although ADHD-IN uniquely predicted academic impairment and social difficulties, SCT did not. Conclusion: This study provides the first evidence for the validity of SCT among children outside of North America or Western Europe.<\/jats:p>","DOI":"10.1177\/1087054715597470","type":"journal-article","created":{"date-parts":[[2015,8,5]],"date-time":"2015-08-05T21:59:31Z","timestamp":1438811971000},"page":"667-672","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":39,"title":["Validity of Sluggish Cognitive Tempo in South America: An Initial Examination Using Mother and Teacher Ratings of Chilean Children"],"prefix":"10.1177","volume":"21","author":[{"given":"Marta","family":"Belmar","sequence":"first","affiliation":[{"name":"Catholic University of the Maule, Talca, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mateu","family":"Servera","sequence":"additional","affiliation":[{"name":"University of the Balearic Islands, Palma, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen P.","family":"Becker","sequence":"additional","affiliation":[{"name":"Cincinnati Children\u2019s Hospital Medical Center, Cincinnati, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.
