Adult attachment interview was developed by Mary Main and her colleagues, this is a semi-structured interview that takes about one hour to administer. It involves about twenty questions and has extensive research validation to support it. A good description can be found in Chapter 19 of Attachment Theory, Research and Clinical Applications, edited by J. Cassidy and P. R. Shaver, Guilford Press, NY, 1999. The chapter title is "The Adult Attachment Interview: Historical and Current Perspectives," and is written by E. Hesse.
Some of the strongest external validation of the measures involves its demonstrated ability to predict interviewees' children's classifications in the Strange Situation. The measure also has shows to have some overlap with attachment constructs measured by the less time-intensive measures of the peer/romantic attachment tradition (Hazan & Shaver, Bartholomew), as reported by Shaver, P. R., Belsky, J., & Brennan, K. A. (2000). However, it should be noted that there are important differences in what is measured by the AAI--rather than being a measure of romantic attachment, it taps primarily into a person's state of mind regarding their attachment in their family of origin (nuclear family).
