Within forensic psychology research, MDS has had its most notable impact on offender profiling. This chapter provides an introduction to multidimensional scaling (MDS), and describes its use and utility within forensic psychology research. It also provides some examples of the application of MDS, one of which is its usage to the multivariate nature of sexual assault behaviour. A form of MDS known as partial order scalogram analysis with coordinates (POSAC) has been used to establish that the shape of criminal networks can vary greatly, and identify that the strictness of hierarchy within a network is related to aspects of group communication. MDS techniques have also been used to examine psychometric test structure. Researchers have explored the latent structure of psychopathy as appraised via the Psychopathy Checklist-Revised (PCL-R), in which an underlying facet structure is observed that is consistent with theory. However, the full utility of MDS approach remains underappreciated.
