This study presents the results on its short-term effectiveness following the first national implementation in 18 Croatian cities, with a total of 629 high school students (66.5% male) who completed the program. A design with two measurement sessions (pre-test and post-test) was used to explore the short-term effects of the program on gambling-related knowledge and cognition, frequency of gambling, and various socio-emotional skills. The results showed significant effects when it comes to knowledge, cognitive distortions, and the frequency of sports betting and playing lottery games. Furthermore, the program had no harmful effects on any of the measured variables. The results are interpreted in terms of methodological challenges in measuring effects, possible improvements of the program, and implications for future evaluation research.<\/jats:p>","DOI":"10.3390\/ijerph181910100","type":"journal-article","created":{"date-parts":[[2021,9,27]],"date-time":"2021-09-27T04:55:33Z","timestamp":1632718533000},"page":"10100","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Short-Term Effectiveness of the Youth Gambling Prevention Program \u201cWho Really Wins?\u201d\u2014Results from the First National Implementation"],"prefix":"10.3390","volume":"18","author":[{"given":"Dora","family":"Dodig Hundric","sequence":"first","affiliation":[{"name":"Department of Behavioral Disorders, Faculty of Education and Rehabilitation Sciences, University of Zagreb, 10 000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7646-6283","authenticated-orcid":false,"given":"Sabina","family":"Mandic","sequence":"additional","affiliation":[{"name":"Department of Behavioral Disorders, Faculty of Education and Rehabilitation Sciences, University of Zagreb, 10 000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8107-8448","authenticated-orcid":false,"given":"Neven","family":"Ricijas","sequence":"additional","affiliation":[{"name":"Department of Behavioral Disorders, Faculty of Education and Rehabilitation Sciences, University of Zagreb, 10 000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Sulkunen, P., Babor, T.F., Ornberg, J.C., Egerer, M., Hellman, M., Livingstone, C., Marionneau, V., Nikkinen, J., Orford, J., and Room, R.
