<p>Attachment theory suggests that early parental relationships influence an individual’s attachment style in adulthood. While extensive research has examined the impact of parental attachment on romantic relationships, the role of father-daughter attachment in shaping romantic attachment styles remains understudied, particularly across cultural contexts. This study explores the relationship between father-daughter attachment styles and romantic attachment styles in women from the United Kingdom and Turkey. Participants (TR = 254, UK = 83) completed measures assessing their attachment to their fathers (e.g., secure, dependent, parentified, fearful, distant) and their romantic attachment styles (secure, avoidant, preoccupied, unresolved). The findings revealed that women with secure father-daughter attachments were more likely to have secure romantic relationships, whereas parentified and distant father-daughter attachments were associated with less secure relationship styles. Cultural differences emerged, with Turkish women reporting more secure and preoccupied romantic attachment styles, while women from the UK exhibited higher levels of avoidant attachment. Notably, fearful father-daughter attachment was positively associated with secure romantic relationships in UK women but not in Turkish women. These findings highlight the critical influence of paternal attachment on romantic relationships and suggest that cultural factors may shape how early attachment experiences translate into adult romantic dynamics. The study contributes to understanding the nuanced role of father-daughter bonds in romantic attachment and emphasizes the need for cross-cultural perspectives in attachment research.</p>
