In this randomized controlled trial (RCT)\u2010study, we add to this research by optimizing core procedural as well as teaching components in a phonics\u2010directed intervention and extend the RCT reading intervention research into a semi\u2010transparent language context. The aim of the present study was to evaluate the effects of a novel Swedish intensive phonics program. This randomized controlled pre\u2010test and post\u2010test intervention study targeted second\u2010grade students with early reading difficulties. Students were identified by a repeated screening procedure and allocated to intervention (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200934) and control (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200934) conditions. A 9\u2010week intensive phonics\u2010based program was administrated one\u2010to\u2010one, by special education teachers in Swedish mainstream elementary schools. Results show an improvement in the intervention group, compared with the controls on all outcome measures. Findings indicate that the supplementary phonics program, delivered with high intensity, can significantly increase word reading skills and reading comprehension in second\u2010grade students with early reading difficulties.\n                  <\/jats:p>","DOI":"10.1002\/dys.1751","type":"journal-article","created":{"date-parts":[[2023,9,12]],"date-time":"2023-09-12T21:13:41Z","timestamp":1694553221000},"page":"290-311","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Effects of a phonics intervention in a randomized controlled study in Swedish second\u2010grade students at risk of reading difficulties"],"prefix":"10.1002","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7495-1384","authenticated-orcid":false,"given":"Hanna","family":"Lindstr\u00f6m\u2010Sandahl","sequence":"first","affiliation":[{"name":"Department of Behavioural Sciences Link\u00f6ping University  Link\u00f6ping Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7824-1750","authenticated-orcid":false,"given":"\u00c5sa","family":"Elw\u00e9r","sequence":"additional","affiliation":[{"name":"Department of Behavioural Sciences Link\u00f6ping University  Link\u00f6ping Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5234-5495","authenticated-orcid":false,"given":"Stefan","family":"Samuelsson","sequence":"additional","affiliation":[{"name":"Department of Behavioural Sciences Link\u00f6ping University  Link\u00f6ping Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0446-0827","authenticated-orcid":false,"given":"Henrik","family":"Danielsson","sequence":"additional","affiliation":[{"name":"Department of Behavioural Sciences Link\u00f6ping University  Link\u00f6ping Sweden"},{"name":"The Swedish Institute for Disability Research Link\u00f6ping University  Link\u00f6ping Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,9,12]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4899-7568-3_23"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/0014402914532234"},{"key":"e_1_2_10_4_1","unstructured":"Aust F. &Barth M.(2020).papaja: Create APA manuscripts with R markdown.
