An earlier report focused on the therapeutic effectiveness of certain components of the treatment process (i. e., electricity, convulsion, unconsciousness).3 Results indicated that the experimental variations of actual or simulated electroshock did not differ in the therapeutic effectiveness to an extent greater than chance. The present report is, therefore, concerned not with the electroshock variable but with (a) the prediction of improvement and (b) the further understanding of the concomitants of improvement.
