This study examined the psychometric properties of a newly translated Italian version of the Experiences in Close Relationships-Revised (ECR–R) Scale. The sample comprised 1,363 adults (906 women, 456 men, 1 unreported sex; ages 18–64 yr., M=33.4, SD=8.9; 84.4% reported being engaged in a romantic relationship, 9.4% declared being single), all living in Italy and speaking Italian as their first language. Exploratory and confirmatory factor analyses showed the expected bi-factorial (anxiety/avoidance) structure and a close correspondence between factors and scales. Test-retest and internal consistency reliabilities were adequate. Correlations with the Relationship Questionnaire, a categorical measure of attachment, and with the Dyadic Adjustment Scale were consistent with the theoretical relations among the constructs. The findings confirm the transcultural validity of the ECR–R.
