Bartholomew, K., & Shaver, P. R. (1998). Methods of assessing adult attachment: Do they converge? In J. A. Simpson & W. S. Rholes (Eds.), Attachment Theory and Close Relationships (pp. 25-45). New York: Guilford.
Measures of adult attachment differ in terms of domain (family, peer, or romantic relationships), method (interview, Q-Sort, or self-report), dimensionality (categories, prototype ratings, or dimensions), and categorization systems. Despite such differences, the measures converge to varying degrees, especially when reliability and statistical power are sufficiently high.
