Summary

The Structured Interview for Schizotypy-Revised (SIS-R) shows good reliability for most schizotypal symptoms. However, many signs lack sufficient reliability, but a shortened SIS-R is a dependable tool for schizotypy research.

Area of Science:

  • Psychiatry
  • Psychometrics
  • Clinical Psychology

Background:

  • The Structured Interview for Schizotypy (SIS) was previously developed by Kendler.
  • Schizotypy assessment requires reliable and valid instruments for accurate diagnosis and research.
  • Standardizing rating procedures is crucial for improving interview reliability.

Purpose of the Study:

  • To assess the test-retest reliability of the revised Structured Interview for Schizotypy-Revised (SIS-R).
  • To evaluate the reliability of individual schizotypal symptoms and signs within the SIS-R.
  • To determine if a modified SIS-R can serve as a reliable instrument for measuring schizotypal features.

Main Methods:

  • A robust test-retest design was employed with 42 psychiatric patients, primarily those with personality disorders.

  • Interviews were conducted by different interviewers at both time points, with a mean interval of 19 days.
  • The linear-weighted kappa statistic was used to evaluate the reliability of the SIS-R ratings.

    • Main Results:

    • Most schizotypal symptoms assessed by the SIS-R demonstrated reliable measurement.
    • A significant portion of the schizotypal signs within the SIS-R did not achieve sufficient reliability levels.
    • Excluding unreliable items resulted in a shortened SIS-R that proved to be a reliable research instrument.

    Conclusions:

    • The SIS-R is a reliable tool for assessing most schizotypal symptoms.
    • Certain schizotypal signs require further refinement to enhance their reliability.
    • A revised and shortened version of the SIS-R offers a dependable method for measuring schizotypal features across its dimensions.
