This version of the classification system MTC:CM3 has three major changes: (1) partitioning of the "regressed/fixated" dichotomy into separate factors -- level of social competence and degree of fixation on children; (2) filling of the empirically determined gap between the object-oriented offender and the antisocial, exploitative offender with a new type -- the "narcissistic" type; and (3) differentiation of the violence in the sexual offense into nonsadistic and sadistic components. For the study, child molesters committed to the Treatment Center were classified by MTC:CM3 and variables from the clinical files were coded and rationally grouped by developmental period and subjected to principal-components analysis (PCA). Regression analyses yielded three path models indicating that the new subtypes created had distinct developmental courses and adult adaptations. 1 table, 4 figures, 67 references.
