This study aimed to determine the overall fit of Self-Determination Theory Model\u00a0for Health Behavior to the data obtained from a sample of smokers hospitalized with acute coronary syndrome, and to identify the\u00a0predictors of smoking status six months after clinical discharge.Material and Methods: The sample included 110 participants, regular smokers, hospitalized due to acute coronary syndrome.\u00a0Questionnaires were administered to assess autonomous self-regulation, perceived competence, family support, depressive symptoms\u00a0and meaning in life. Participants were asked if they were currently smokers six months after clinical discharge.Results: The results showed that the process variables specified by Self-Determination Theory fit the data well. Perceived competence\u00a0predicted abstinence from smoking six months after clinical discharge.Discussion: Our findings have similar characteristics to other international samples in which Self-Determination Theory models havebeen tested. It is important to facilitate perceived competence, as the patients who continue to smoke have shorter length of life.Conclusion: This study highlights the importance of considering clinical interventions based on Self-Determination Theory to facilitatesmoking cessation.<\/jats:p>","DOI":"10.20344\/amp.7926","type":"journal-article","created":{"date-parts":[[2017,2,27]],"date-time":"2017-02-27T16:37:27Z","timestamp":1488213447000},"page":"34-40","source":"Crossref","is-referenced-by-count":6,"title":["Motivation to Quit Smoking after Acute Coronary Syndrome"],"prefix":"10.20344","volume":"30","author":[{"given":"V\u00e2nia","family":"Rocha","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina","family":"Guerra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina","family":"Lemos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00falia","family":"Maciel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geoffrey","family":"Williams","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"8464","published-online":{"date-parts":[[2017,1,31]]},"container-title":["Acta M\u00e9dica Portuguesa"],"original-title":[],"link":[{"URL":"https:\/\/www.actamedicaportuguesa.com\/revista\/index.php\/amp\/article\/download\/7926\/4893","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.actamedicaportuguesa.com\/revista\/index.php\/amp\/article\/download\/7926\/4893","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,10,25]],"date-time":"2022-10-25T21:05:20Z","timestamp":1666731920000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.actamedicaportuguesa.com\/revista\/index.php\/amp\/article\/view\/7926"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,1,31]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2017,1,31]]}},"URL":"https:\/\/doi.org\/10.20344\/amp.7926","relation":{},"ISSN":["1646-0758","0870-399X"],"issn-type":[{"value":"1646-0758","type":"electronic"},{"value":"0870-399X","type":"print"}],"subject":[],"published":{"date-parts":[[2017,1,31]]}}}
