Specifically, it is assumed that the relationship between item endorsement and the latent trait is monotonically increasing. It is possible, however, that the item response process for these inventories actually follows an ideal-point process in which respondents seek to endorse items that best describe them, leading to non-monotonic relations between item responses and latent traits. This study examined whether the item response process underlying the Experiences in Close Relationships-Revised (ECR-R; Fraley, Waller, & Brennan, 2000)--a commonly used self-report measure of adult attachment styles--is best understood as a dominance or ideal-point process. The authors compared the fits of alternative models in a sample of 1,293 adults. Results showed that the ideal point model provided a good account of the response process, and provided better interpretability for the full trait continuum. Importantly, people who were the most insecure were the most likely to be scored differently under these two item response models.
