PHALLOMETRIC DIAGNOSIS WITH NONADMITTERS

The phallometric method of assessing erotic value of presented stimuli has two main tasks, one is in the breaking down of complex (potentially) sexual stimuli into components, the other is in diagnosing anomalous erotic preferences in 'Nonadmitters', i.e. in persons whose behaviour would imply there is such an anomaly, but who deny its presence. Differentiation between Admitters and Nonadmitters was attained by two verbal Admitter scales. Comparison of the scores on these scales with results of phallometric assessment showed (by mutual validation) that the phallometric method diagnoses Admitters more accurately than Nonadmitters. After that, the validity was tested of a new mode of the phallometric method, designed for diagnosing pedo- or hebephilia in Nonadmitters. In cases of homosexual pedophilia or hebephilia (but not in the heterosexual cases) the new Nonadmitter mode was superior to the Standard procedure. © 1979.
