Abstract

Introduction: The investigation of attachment processes during middle childhood and early adolescence has been hampered by a relative lack of measures for this age group.The aim of this study was investigating the psychometric properties of Experiences in Close Relationships Revise-Scale for use with children and adolescents (ECR-RC). It is a self-report questionnaire for measuring attachment anxiety and avoidance.  Method: Sample size of 430 students was selected by stratified multistage cluster sampling in Tehran. Attachment Security Scale (ASS) was implemented to calculate the divergent validity of ECR-RC.  Results: Results of factor analyze indicated that two factor model of ECR-RC fit in Iranian sample in each relational domain (Mother-Father). Cronbach's alpha coefficient of ECR-RC was above 0.80 and the limit was satisfactory. Furthermore the test-retest reliability of        ECR-RC over a four week period was more than 0.69. Correlation coefficient analysis showed that ECR-RC has a significant negative relationship with ASS which shows the divergent validity.Conclusion: Factor structure, reliability and validity of the ECR-RC for research applications and clinical diagnostics were within acceptable limits. It’s can be said that ECR-RC is useful and reliable tool for attachment researches in different domain of relationship.   Introduction: The investigation of attachment processes during middle childhood and early adolescence has been hampered by a relative lack of measures for this age group.The aim of this study was investigating the psychometric properties of Experiences in Close Relationships Revise-Scale for use with children and adolescents (ECR-RC).
