(2025). Comparing European Emerging Adults Online Romantic Relationships: A Short Longitudinal Study. Human Arenas. https://doi.org/10.1007/S42087-025-00505-X2522-579010.1007/s42087-025-00505-xhttps://hdl.handle.net/20.500.14352/132562The paper was written in connection with the project "The dynamics of adolescent couple relation-ships in the face of social constraints caused by the COVID-19 pandemic" founded by the Polish National Agency for Academic Exchange (NAWA) on the basis of an agreement BPN/GIN/2021/1/00058/U/00001 with the University of Lodz (UL).This study investigates the dynamics of online romantic relationships among emerging adults from three European countries: Italy, Poland, and Spain. Specifically, it explores (a) the quality and stability over a five-week period of these relationships, and (b) cross-national differences in relationship management. A sample of 115 participants completed questionnaires measuring relationship quality, emotional communication strategies, and online behaviors. Data were analyzed using nonparametric repeated measures and group comparisons. Results revealed overall stability in romantic relationships, with Italian participants showing increased online jealousy, Polish participants enhancing relationship identification, and Spanish participants maintaining lower levels of jealousy and control. These findings suggest cultural nuances in how young adults navigate online romantic interactions, highlighting the influence of traditional values and digital contexts. The study underscores the need for longitudinal research to understand how digital platforms shape romantic relationships over time and across cultures.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article2522-5804https://doi.org/10.1007/s42087-025-00505-xhttps://produccioncientifica.ucm.es/documentos/6857095b55e1544d97879e2dhttps://www.scopus.com/pages/publications/105007066119https://www.webofscience.com/wos/woscc/full-record/WOS:001500271500001https://link.springer.com/article/10.1007/s42087-025-00505-xhttps://link.springer.com/journal/42087restricted access316.47316.635159.942316.637.015.337.015:316316.74:37Online relationshipsRomantic relationshipsAdolescenceCultural differencesSocial mediaPsicología evolutivaPsicología Social (Sociología)Psicología social (Psicología)Sociología de la educación (Educación)Inteligencia emocionalComunicación interpersonalInvestigación en la comunicaciónMétodos de investigación en educación61 Psicología6106.04 Análisis Experimental de la Conducta6302.02 Psicología Social6106.03 Emoción6114.07 Cultura y Personalidad5199 Otras Especialidades Antropológicas5802.04 Niveles y Temas de Educación6306.05 Sociología de la Educación
