Changing daily routines, avoiding gatherings, social isolation, financial difficulties, and reduced privacy are some of the many changes that “coexistence” with the Covid-19 pandemic has brought. Numerous changes that occur leave a mark on the young population and lead to stress that can impair their quality of their relationships. In this study, three dimensions of relationship quality were studied: relationship maintenance strategies, intimacy and participation in joint leisure activities. Given that the pandemic has introduced a number of challenges in student relationships, and especially given that the pandemic is still ongoing and that the current situation is uncertain and constantly changing, it is necessary to study the nature of the relationship between stress and these dimensions of relationship quality. Therefore, the aim of this study was to examine the association between the stress associated with the pandemic and different indicators of student relationships quality. A quantitative study was conducted on a sample of 263 students of the University of Zagreb who have been in a relationship for a minimum of three months. The survey questionnaire was shared via Facebook in various groups that bring together a large number of students. The results showed that there was no statistically significant correlation of Covid-19 pandemic related stress with relationship maintenance strategies and intimacy assessment in a relationship. However, a statistically significant positive, albeit low, correlation was found between pandemic related stress and the frequency of participation in joint activities. Results also showed that students declare high levels of relationship maintenance strategies and intimacy in their relationships, while the frequency of participation in joint activities varies depending on the type of activity. Further studies are needed on this topic to provide young people with help and guidance on how to deal with pandemic stress and maintain a quality relationship, despite the many dis(advantages) and restrictions of living in the “new normal” environment.
