Development and Validation of Adult Attachment Inventory

AbstractThis paper presents an account of the development, reliability, and validity of Adult Attachment Inventory. One thousand four hundred and eighty students from the University of Tehran (860 females, 620 males) were included in this study. All participants were asked to complete Adult Attachment Inventory (AAI), Coopersmith Self-Esteem Inventory (SEI), and Inventory of Interpersonal Problems (IIP-127). Results supported three-factor structure, convergent and discriminant validity, internal consistency, and test-retest reliability of the AAI. It was concluded that the AAI can be considered as a reliable and valid scale to measure the attachment styles including secure, avoidant, and ambivalent in Iranian samples
