The aim of this research was to determine the relationship between long-distance relationship satisfaction and different types of individual attachment (secure, anxious and avoidant), as well as to examine whether there are differences in long-distance relationship satisfaction, taking into account the participant's gender as a relevant variable. A total of 106 adult participants (38 men and 68 women) who are in a long-distance relationship and have been in a romantic relationship for more than a year took part in the research. In order to collect data, the task of the participants was to complete the Marital Satisfaction Scale and the Attachment Scale as a state. The Pearson correlation coefficient and the t-test were used to analyze the data thus obtained. Consistent with the assumptions, the results of this study suggest a strong positive correlation between long-distance relationship satisfaction and secure attachment, and a moderate negative correlation between long-distance relationship satisfaction and participants' avoidant attachment style. However, contrary to expectations, no statistically significant correlation was found between long-distance relationship satisfaction and anxious attachment style. Also, the research results show that women are, on average, more satisfiedwith longdistance relationships than men, which is not in line with the initial assumptions.
