The participants were 2045 third-, fourth- and fifth-grade students from Estonia, Finland, Norway, Portugal, Serbia and Sweden. The Expectancy-Value Scale (EVS) was found to be suitable for early grades of primary education in measuring competence self-perceptions and subjective task values relative to the mathematics field. The results indicate a good model fit aligned with the expectancy-value theory. The EVS dimensions showed good reliability, and scalar invariance was established. However, findings also indicated high correlations between some of the EVS dimensions, which is well documented for students at this age. The findings are discussed relative to the \u2018expectancy-value\u2019 theory framework and students\u2019 age. <\/jats:p>","DOI":"10.1177\/07342829221144868","type":"journal-article","created":{"date-parts":[[2022,12,13]],"date-time":"2022-12-13T09:37:05Z","timestamp":1670924225000},"page":"343-350","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Contribution to the Validation of the Expectancy-Value Scale for Primary School Students"],"prefix":"10.1177","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7193-2284","authenticated-orcid":false,"given":"Francisco","family":"Peixoto","sequence":"first","affiliation":[{"name":"ISPA \u2013 Instituto Universit\u00e1rio, Lisbon, Portugal"}]},{"given":"Jelena","family":"Radi\u0161i\u0107","sequence":"additional","affiliation":[{"name":"University of Oslo, Oslo, Norway"}]},{"given":"Ksenija","family":"Krsti\u0107","sequence":"additional","affiliation":[{"name":"University of Belgrade, Belgrade, Serbia"}]},{"given":"Kajsa Yang","family":"Hansen","sequence":"additional","affiliation":[{"name":"University West, Trollh\u00e4ttan, Sweden"}]},{"given":"Anu","family":"Laine","sequence":"additional","affiliation":[{"name":"University of Gothenburg, Gothenburg, Sweden"}]},{"given":"Aleksandar","family":"Baucal","sequence":"additional","affiliation":[{"name":"University of Belgrade, Belgrade, Serbia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6500-9837","authenticated-orcid":false,"given":"Maarja","family":"S\u00f5rmus","sequence":"additional","affiliation":[{"name":"University of Helsinki, Helsinki, Finland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8645-246X","authenticated-orcid":false,"given":"Lourdes","family":"Mata","sequence":"additional","affiliation":[{"name":"ISPA \u2013 Instituto Universit\u00e1rio, Lisbon, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2022,12,13]]},"reference":[{"key":"bibr1-07342829221144868","doi-asserted-by":"publisher","DOI":"10.1037\/0033-295X.111.4.1061"},{"key":"bibr2-07342829221144868","volume-title":"Confirmatory factor analysis for applied research","author":"Brown T.
