This study aimed to investigate the predictive ability of relationship status, anxiety, mindfulness, and resilience in relation to the two orthogonal dimensions of adult attachment: attachment anxiety and attachment avoidance. 156 participants completed measures assessing relationship status, adult attachment, anxiety, mindfulness and resilience. The results showed that resilience and the relationship status of single significantly predicted attachment anxiety, whereas anxiety and being either single or divorced significantly predicted attachment avoidance. A significant mediating role of resilience in the prediction of attachment anxiety from being single was also observed. The main implications of this study provided preliminary support for the significant predictive value of resilience in attachment anxiety.
