An experimental group of 32 process schizophrenics was treated with regressive ECT, while a control group of 2l patients was treated with ataraxic drugs and psychotherapy. All patients were evaluated at admission and at or after discharge, using four sources of evaluation: self-ratings, psychological tests, relatives' ratings, and ratings by referring therapists. Statistical analysis of 55 variables indicated that the two groups were essentially equivalent at admission but showed significant differences on 28 of the 55 variables after discharge. All of the variables favored the experimental group treated with regressive ECT.Abstract Teaser
