Applied multidimensional scaling to similarity data to produce a model of Attachment Q-Set (AQS) items as points in a 3-dimensional space. Represented criterion sorts, individual Q-sorts, and empirical correlates as vectors, interpreting each according to the vector's contributions from the three global dimensions. Tested the model's validity and compared the system with three sets of published AQS criterion scales, examining connections among the latter within the model's framework. (Author/KB)
