As the rate of divorce in the Republic of Croatia is constantly increasing, there is an increasing number of children growing up in incomplete families. In accordance with that, there is a growing interest in determining the consequences that divorce has in functioning and psychological well-being of children, and it is of particular importance to identify the relationships between reactions to parental divorce and the quality of functioning in close relationships in adulthood. Accordingly, the aim of this research was to examine the relationship between quality of parental and romantic attachment and the fear of intimacy in romantic relationship of adults whose parents are divorced. For this purpose, an online correlation survey was conducted on a convenience sample of 344 participants in the age 18-54. The average age of participants at the time of parental divorce was 11 years and on the questions about their own reactions on parental divorce they answered retrospectively. Participants completed the Experience of Parental Divorce Scale, Perceived Social Support Scale, Fear of Intimacy Components Questionnaire and Modified Version of Brennan’s Experiences in Close Relationships Inventory. Apart from the latent structure of the instruments, gender differences were analysed on the used variables, their intercorrelations and predictive contribution of different own negative reactions to the parental divorce and the attachment to partner and parents in explaining the variance of the fear of intimacy. Gender differences in the fear of intimacy in romantic relationship were not found, but it is observed that male participants refer about, in average, less negative emotional consequences of the divorce and show greater perceived social support during the divorce. Results also revealed, that in male participants, as well as in female participants in this study, fear of intimacy in romantic relationship is positively correlated with negative reactions to divorce and the dimensions of avoidance and anxiety in relationships with partner, father and mother. Moreover, on both subgroups, perceived social support during the divorce is negatively correlated with negative reactions to divorce, fear of intimacy in romantic relationship and dimensions of avoidance and anxiety in relationships with partner, father and mother. On the subgroup of men, there was significant positive contribution of avoidance in relationships with partner and father in explaining the variance of the fear of intimacy in romantic relationships. On the subgroup of women, significant positive contribution of avoidance and anxiety in relationship with partner and avoidance in relationship with mother in explaining of the fear of intimacy variance was observed.
