The attachment Q-set is a tool used for assessing attachment in children aged 1 to 5, and consists of 90 cards, on which statements describing secure-base behaviour are written. Participating children are observed and rated for each statement. The test is designed to cover the spectrum of attachment-relative behaviours, and provides a score along a continuum of secure-insecure.
