title: Continuity and change in the measurement of infant attachment: comment on Fraley and Spieker (2003).
abstract: R.C. Fraley and S.J. Spieker (2003) refocused attention on the important question of continuous versus categorical measurement of infant attachment. This commentary begins with a brief response to Fraley and Spieker's position. Next, it highlights the usefulness of the categorical approach by reviewing some of the major advances in the field that have been fostered by a categorical approach. These include the identification of the disorganized attachment group, the development of the concept of conditional behavioral strategies, the creation of systems for coding attachment beyond infancy, and a greater understanding of cross-generational associations. The author then makes several propositions for future research that are necessary for clarifying how best to measure infant attachment.
