To this end, a confirmatory factor analysis was carried out to evaluate whether the Hajli model applied to this sample, as well as multigroup CFA to measure invariance across gender and across following influencers or not. Finally, the path analysis evaluates the intersection of social media addiction with the Hajli model (2014). The results confirmed the Hajli model as well as the inclusion in the model of social media addiction as a variable that contributes to purchase intention on social media. Configural, metric, and scalar invariance were found across genders and across the following influencers or not. Also, the values found for internal consistency and composite reliability, convergent reliability, and discriminant reliability were within the reference values.<\/jats:p>","DOI":"10.3390\/digital4010008","type":"journal-article","created":{"date-parts":[[2024,2,1]],"date-time":"2024-02-01T11:25:55Z","timestamp":1706786755000},"page":"169-181","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Contribution of Social Media Addiction on Intention to Buy in Social Media Sites"],"prefix":"10.3390","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0560-1756","authenticated-orcid":false,"given":"\u00c2ngela","family":"Leite","sequence":"first","affiliation":[{"name":"Centre for Philosophical and Humanistic Studies, Universidade Cat\u00f3lica Portuguesa, 4710-362 Braga, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8099-2828","authenticated-orcid":false,"given":"Anabela","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"Centre for Philosophical and Humanistic Studies, Universidade Cat\u00f3lica Portuguesa, 4710-362 Braga, Portugal"},{"name":"Faculty of Philosophy and Social Sciences, Universidade Cat\u00f3lica Portuguesa, 4710-362 Braga, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Margarida","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Faculty of Philosophy and Social Sciences, Universidade Cat\u00f3lica Portuguesa, 4710-362 Braga, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1081-5276","authenticated-orcid":false,"given":"S\u00edlvia","family":"Lopes","sequence":"additional","affiliation":[{"name":"Faculty of Philosophy and Social Sciences, Universidade Cat\u00f3lica Portuguesa, 4710-362 Braga, Portugal"},{"name":"CICPSI, Faculdade de Psicologia, Universidade de Lisboa, 1649-013 Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"282","DOI":"10.1016\/j.techfore.2017.11.026","article-title":"How social commerce constructs influence customers\u2019 social shopping intention?
