In addition, we examined whether any significant group differences are due to differences between groups in attention. Thirty-three Canadian children with RD (51.5% female;\n                    <jats:italic toggle=\"yes\">M<\/jats:italic>\n                    <jats:sub>age<\/jats:sub>\n                    = 10.80 years), 35 with MD (60.0% female;\n                    <jats:italic toggle=\"yes\">M<\/jats:italic>\n                    <jats:sub>age<\/jats:sub>\n                    = 10.79 years), 37 with comorbid RDMD (45.9% female;\n                    <jats:italic toggle=\"yes\">M<\/jats:italic>\n                    <jats:sub>age<\/jats:sub>\n                    = 10.79 years), and 42 chronological-age (CA) controls (64.3% female;\n                    <jats:italic toggle=\"yes\">M<\/jats:italic>\n                    <jats:sub>age<\/jats:sub>\n                    = 10.82 years) were assessed on reading, mathematics, general cognitive ability, and attention tasks. Their teachers also rated their anxiety, depression, somatic complaints, and social withdrawal. Results of analyses of variance showed that children with comorbid RDMD exhibited significantly higher levels of anxiety and depression compared only to the CA controls. However, after controlling for attention, these group differences were no longer significant. These findings suggest that children with comorbid RDMD may be at greater risk for anxiety and depression, although attention difficulties likely contribute to these differences.\n                  <\/jats:p>","DOI":"10.1177\/00222194251335313","type":"journal-article","created":{"date-parts":[[2025,4,28]],"date-time":"2025-04-28T07:54:17Z","timestamp":1745826857000},"page":"108-118","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Do Children With Comorbid Reading and Mathematics Difficulties Experience More Internalizing Problems?"],"prefix":"10.1177","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4771-3476","authenticated-orcid":false,"given":"Ana Paula Alves","family":"Vieira","sequence":"first","affiliation":[{"name":"University of Alberta, Edmonton, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9081-992X","authenticated-orcid":false,"given":"George K.","family":"Georgiou","sequence":"additional","affiliation":[{"name":"University of Alberta, Edmonton, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuliya","family":"Kotelnikova","sequence":"additional","affiliation":[{"name":"University of Alberta, Edmonton, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,4,28]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"crossref","unstructured":"Aaron P.
