The Inventory of Childhood Memories and Imagining (ICMI) can identify college students at risk for schizophrenia spectrum disorders using MMPI codes. High ICMI scores predict risk, while low scores predict absence of risk.

Area of Science:

  • Psychology
  • Psychopathology
  • Clinical Psychology

Background:

  • The Minnesota Multiphasic Personality Inventory (MMPI) is a widely used tool for psychological assessment.
  • Identifying individuals vulnerable to schizophrenia spectrum disorders is crucial for early intervention.
  • The Inventory of Childhood Memories and Imagining (ICMI) assesses imaginative processes, which may relate to psychopathology.

Purpose of the Study:

  • To evaluate the diagnostic efficiency of the ICMI in identifying college students with MMPI codes indicative of schizophrenia spectrum vulnerability.
  • To compare MMPI profiles of individuals with high imaginative tendencies (fantasizers) versus a control group.

Main Methods:

  • Administered the MMPI and ICMI to 1,200 college students.
  • Utilized diagnostic efficiency statistics to determine predictive power of ICMI cutoff scores.

  • Formed a fantasizer group (n=30) and a control group (n=30) based on ICMI scores.

    • Main Results:

    • ICMI scores >= 29 demonstrated good positive predictive power for identifying schizophrenia spectrum MMPI codes.
    • ICMI scores < 29 showed very good negative predictive power.
    • Fantasizers were significantly more likely (70%) to exhibit MMPI codes associated with schizophrenia vulnerability compared to controls (3.33%).
    • 66.67% of fantasizers had three or more elevated MMPI clinical scales, compared to 70% of controls with non-elevated scores.
    • The modal MMPI profile for fantasizers was 8-9, suggesting heightened risk for eccentric thinking and Cluster A or B personality organization.

    Conclusions:

    • The ICMI is an effective tool for identifying college students at risk for schizophrenia spectrum disorders.
    • Individuals with high imaginative tendencies (fantasizers) show distinct MMPI profiles associated with increased vulnerability to schizophrenia and specific personality organization patterns.
