Attachment theory suggests that early relational experiences shape individuals' internal working models and influence romantic relationship dynamics in adulthood. Dating violence remains a significant interpersonal and societal concern among emerging adults. The present study examined the association between adult attachment styles and attitudes toward dating violence, as well as gender differences in these variables. The sample consisted of 194 emerging adults (115 women, 79 men) aged 18-25 in Turkey. Participants completed the Relationship Scales Questionnaire and the Dating Violence Attitude Scale via online data collection. Ethical approval was obtained from the Mersin University ethics committee, and informed consent was secured from all participants. Data were analyzed using Pearson correlation and independent samples t-tests. Correlation analyses revealed a significant positive association between dismissing attachment and attitudes toward sexual dating violence (r = .127, p < .05). A significant negative association was found between preoccupied attachment and attitudes toward sexual dating violence (r = −.129, p < .05). No other significant associations emerged between attachment styles and other dating violence dimensions. Independent samples t-tests indicated a significant gender difference in overall dating violence attitudes, with women reporting higher scores than men, t(192) = −5.40, p < .001. However, attachment styles did not significantly differ by gender. Findings suggest that insecure attachment patterns may be specifically linked to sexual dating violence attitudes rather than to broader violence dimensions. The results highlight the importance of considering attachment-based relational dynamics in preventive interventions targeting dating violence among emerging adults.
