Reliability, Validity, and Factor Structure of Experiences in Close Relationships –Revised-Scale for use with children and adolescents (ECR-RS)

Introduction: The investigation of attachment processes during middle childhood and earlyadolescence 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 CloseRelationships Revise-Scale for use with children and adolescents (ECR-RC). It is a self-reportquestionnaire for measuring attachment anxiety and avoidance.Method: Sample size of 430 students was selected by stratified multistage cluster sampling inTehran. Attachment Security Scale (ASS) was implemented to calculate the divergent validity ofECR-RC.Results: Results of factor analyze indicated that two factor model of ECR-RC fit in Iranian samplein each relational domain (Mother-Father). Cronbach s alpha coefficient of ECR-RC was above 0.80and the limit was satisfactory. Furthermore the test-retest reliability ofECR-RC over a four week period was more than 0.69. Correlation coefficient analysis showed thatECR-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 andclinical diagnostics were within acceptable limits. It’s can be said that ECR-RC is useful and reliabletool for attachment researches in different domain of relationship.
