A total of 3109 students included in the \u201cPsychological Health and Well-being\u201d study of the School Observatory participated, including 1618 females and 1491 males aged between 11 and 18 years old (M = 14.45; SD = 1.88), belonging to different school groups in different regions of the country. Adolescents with higher stress, depression and anxiety levels reported lower levels of competence, confidence and connection, as well as more psychological symptoms and lower life satisfaction. The results also showed that adolescents with higher levels of competence, confidence and connection reported less psychological symptoms and more life satisfaction. Two separate mediation analyses were performed to analyse the role of mental distress and life satisfaction on the relationship between positive youth development indicators and stress, anxiety and depression. These analyses confirmed the predicted relationships and partial mediations between mental distress and life satisfaction. These results should be taken into account in public policies concerning young people\u2019s health and education that should involve both targeted and indicated prevention strategies, including school and community-based interventions, in order to be effective.<\/jats:p>","DOI":"10.3390\/children11060681","type":"journal-article","created":{"date-parts":[[2024,6,3]],"date-time":"2024-06-03T12:19:46Z","timestamp":1717417186000},"page":"681","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Positive Youth Development, Mental Stress and Life Satisfaction in Middle School and High School Students in Portugal: Outcomes on Stress, Anxiety and Depression"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1784-5240","authenticated-orcid":false,"given":"Marina","family":"Carvalho","sequence":"first","affiliation":[{"name":"ISAMB\/Environmental Health\/Medical School, University of Lisbon, 1649-004 Lisboa, Portugal"},{"name":"Centro Hospitalar Universit\u00e1rio do Algarve, 8500-338 Portim\u00e3o, Portugal"},{"name":"Instituto Superior Manuel Teixeira Gomes, 8500-656 Portim\u00e3o, Portugal"}]},{"given":"C\u00e1tia","family":"Branquinho","sequence":"additional","affiliation":[{"name":"ISAMB\/Environmental Health\/Medical School, University of Lisbon, 1649-004 Lisboa, Portugal"},{"name":"Cat\u00f3lica Research Centre for Psychological, Family and Social Well-Being, Faculdade de Ci\u00eancias Humanas, University Cat\u00f3lica Portuguesa, 1649-023 Lisbon, Portugal"}]},{"given":"Barbara","family":"Moraes","sequence":"additional","affiliation":[{"name":"ISAMB\/Environmental Health\/Medical School, University of Lisbon, 1649-004 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9883-0210","authenticated-orcid":false,"given":"Ana","family":"Cerqueira","sequence":"additional","affiliation":[{"name":"ISAMB\/Environmental Health\/Medical School, University of Lisbon, 1649-004 Lisboa, Portugal"},{"name":"Cat\u00f3lica Research Centre for Psychological, Family and Social Well-Being, Faculdade de Ci\u00eancias Humanas, University Cat\u00f3lica Portuguesa, 1649-023 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4440-6868","authenticated-orcid":false,"given":"Gina","family":"Tom\u00e9","sequence":"additional","affiliation":[{"name":"ISAMB\/Environmental Health\/Medical School, University of Lisbon, 1649-004 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4310-2122","authenticated-orcid":false,"given":"Catarina","family":"Noronha","sequence":"additional","affiliation":[{"name":"ISAMB\/Environmental Health\/Medical School, University of Lisbon, 1649-004 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9616-0441","authenticated-orcid":false,"given":"T\u00e2nia","family":"Gaspar","sequence":"additional","affiliation":[{"name":"ISAMB\/Environmental Health\/Medical School, University of Lisbon, 1649-004 Lisboa, Portugal"},{"name":"Life Sciences Department, University Centre of Lisboa, University Lus\u00f3fona de Humanidades e Tecnologias, 1749-024 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5497-9870","authenticated-orcid":false,"given":"Nuno","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"Dire\u00e7\u00e3o Geral de Estat\u00edsticas da Educa\u00e7\u00e3o e Ci\u00eancia, 1200-774 Lisboa, Portugal"}]},{"given":"Margarida Gaspar de","family":"Matos","sequence":"additional","affiliation":[{"name":"ISAMB\/Environmental Health\/Medical School, University of Lisbon, 1649-004 Lisboa, Portugal"},{"name":"Cat\u00f3lica Research Centre for Psychological, Family and Social Well-Being, Faculdade de Ci\u00eancias Humanas, University Cat\u00f3lica Portuguesa, 1649-023 Lisbon, Portugal"},{"name":"Applied Psychology Research Centre Capabilities and Inclusion, Instituto Superior de Psicologia Aplicada, 1140-041 Lisboa, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"D\u0105bkowska, M., Kobierecka-Dziamska, A., and Prusaczyk, M.
