Relationship between schizophrenic thinking and MMPI for process and reactive patients,

Abstract
The relationship between Whitaker Index of Schizophrenic Thinking (WIST) and MMPI [Minnesota Multiphasic Personality Inventory] performance in 25 male Process and Reactive schizophrenic inpatients was studied. A correlation exists between the WIST index and the Sc [schizophrenia] scale of the MMPI for Process patients only. Other MMPI scales highly correlated with each other also correlated with WIST index for the Process group. The lack of association between WIST and MMPI scales for Reactive patients suggested a high degree of behavioral disorganization in these patients. There was a lack of correlation between time and error scores on the WIST and a high variability of time scores on the WIST. The disorganization for the Reactive patients may be understood in terms of disrupted pacing of behavior with respoct to time, a process that may be related to the intrusion of irrelevant event processing.
