Subclinical manifestations of psychosis-proneness, ego strength, and creativity

A study was conducted to examine the joint influence of psychosis-proneness and ego strength on creativity in college students. Psychosis-proneness and ego strength were defined psychometrically by means of Minnesota Multiphasic Personality Inventory and California Psychological Inventory profile, a procedure that resulted in creation of four categories of research subjects: (1) psychosis-prone/high ego strength, (2) psychosis-prone/low ego strength, (3) not psychosis-prone/high ego strength, and (4) not psychosis-prone/low ego strength. As predicted, psychosis-prone persons who were high in ego strength exhibited the highest level of evaluated creativity in their proposed solutions to an engineering problem and also the highest scores on the Remote Associates Test.
