    Summary
    This summary is machine-generated.

    This study investigated defense mechanisms in schizophrenia. Reactive schizophrenics showed a sensitization defense mode, unlike process schizophrenics, suggesting its role in reactive schizophrenia etiology.

    Area of Science:

    • Psychology
    • Psychiatry
    • Clinical Psychology

    Background:

    • Schizophrenia is often categorized into process and reactive subtypes.
    • Understanding the ego defense mechanisms employed by different schizophrenia subtypes is crucial for etiological insights.

    Purpose of the Study:

    • To test the hypothesis that process schizophrenics utilize a repressive ego defense mode, while reactive schizophrenics employ a sensitization mode.
    • To explore the role of defense mechanisms in the development of reactive schizophrenia.

    Main Methods:

    • Administered the Repression-Sensitization scale of the Minnesota Multiphasic Personality Inventory (MMPI).
    • Sample comprised hospitalized individuals diagnosed with process and reactive schizophrenia.
    • Evaluated perceptual behavior under neutral and stress conditions.

    Main Results:

    • Scores for the process schizophrenia group did not indicate a predominant repressive defense mode.
    • Reactive schizophrenics scored significantly higher on the sensitization pole of the scale compared to the process group.
    • Results suggest a distinct pattern of defense mechanism utilization between the two subtypes.

    Conclusions:

    • The findings support the concept of a sensitization defense mode as a characteristic dimension in the etiology of reactive schizophrenia.
    • Defense mechanisms, specifically sensitization, may play a significant role in differentiating and understanding subtypes of schizophrenia.
