Each scale includes 5 items. The major goals of this work were to analyze the psychometric features and validity of the abbreviated 3-item forms of the Satisfaction with Life Scale (SWLS-3) and the Satisfaction with Love Life Scale (SWLLS-3), as well as the measurement invariance (MI) by gender and age in a Portuguese population. The sample comprised 1,271 participants with an average age of 38\u2009years. Confirmatory factor analyses (CFA) demonstrated that the two-dimensional model of SWLS-3 and of SWLLS-3 presented good fit indices. The reliability was adequate. Furthermore, these scales demonstrated MI across gender and age. The correlations of the 3- and 5-item measures with these well-being measures were very similar. Overall, the 3-item versions of the SWLS-3 and the SWLLS-3 are presented as valid and reliable measurement tools. <\/jats:p>","DOI":"10.1177\/21582440241296916","type":"journal-article","created":{"date-parts":[[2024,11,14]],"date-time":"2024-11-14T07:03:09Z","timestamp":1731567789000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["The Abbreviated 3-Item Versions of the Satisfaction With Life Scale and the Satisfaction With Love Life Scale"],"prefix":"10.1177","volume":"14","author":[{"given":"Joana","family":"Neto","sequence":"first","affiliation":[{"name":"Universidade Portucalense, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0112-880X","authenticated-orcid":false,"given":"F\u00e9lix","family":"Neto","sequence":"additional","affiliation":[{"name":"University of Porto, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2024,11,13]]},"reference":[{"key":"bibr1-21582440241296916","doi-asserted-by":"publisher","DOI":"10.1016\/j.paid.2019.109514"},{"key":"bibr2-21582440241296916","doi-asserted-by":"publisher","DOI":"10.1111\/1467-8721.01233"},{"key":"bibr3-21582440241296916","doi-asserted-by":"publisher","DOI":"10.1177\/0956797618774796"},{"key":"bibr4-21582440241296916","doi-asserted-by":"publisher","DOI":"10.1002\/9781118619179"},{"key":"bibr5-21582440241296916","doi-asserted-by":"publisher","DOI":"10.1177\/1088868310391271"},{"key":"bibr6-21582440241296916","doi-asserted-by":"publisher","DOI":"10.4324\/9781315757421"},{"key":"bibr7-21582440241296916","doi-asserted-by":"publisher","DOI":"10.37708\/psyct.v13i2.446"},{"key":"bibr8-21582440241296916","doi-asserted-by":"publisher","DOI":"10.1080\/10705510701301834"},{"key":"bibr9-21582440241296916","volume":"1","author":"Costa M.
