The present study tried to discriminate acute (n = 25) and chronic schizophrenics (n = 25) from borderline patients (BLP; n = 30) on the basis of deviant verbalizations as assessed by the Holtzman Inkblot Technique (HIT). A 30-card version of the HIT was used. It was possible to separate BLPs and schizophrenics with quite good results: 77 of the BLPs, 80 of the acute schizophrenics and 92 of the chronic schizophrenics could be classified correctly based on the less severe deviant verbalizations (DVs) which were more frequent in the BLPs and based on the most severe forms of DVs, i.e. Incoherence, neologism and Perseveration (which were more frequent in the schizophrenic patients). Furthermore, it could be demonstrated that BLPs can be separated from neurotics using the 30-card version of the HIT, the resulting scores being nearly as high as those on the basis of the 45-card version. In another comparison, neurotics (n = 30) were discriminated from normals (n = 35) using the less severe DVs, which were more frequent in the neurotics: here, 74 of the normals and 73 of the neurotics could be classified correctly.
