--- - |2 This study investigated the relations between attachment‐related individual differences and the adoption of interpersonal goals for conflict in romantic relationships. Additionally, it used the truth and bias model to examine how biased and accurate people are in judging their partner's endorsement of conflict goals, as well as how attachment‐related individual differences moderate this bias and accuracy. Ninety‐four romantic couples completed a measure of attachment‐related individual differences and self ‐ and informant reports of interpersonal conflict goals. Results revealed that individuals endorsed conflict goals consistent with their attachment orientations. Furthermore, they displayed biases when estimating their partner's goals, with some of these biases relating to attachment orientations. These results suggest that attachment‐related individual differences may partially guide conflict‐related goals and partner perceptions. - Personal Relationships, Volume 25, Issue 3, Page 411-432, September 2018.
