    Area of Science:

    • Psychiatry
    • Psychology
    • Cognitive Science

    Background:

    • Current definitions of delusion lack clarity and consistency with empirical evidence.
    • The subjective nature of delusions poses challenges for objective assessment.
    • Understanding the fixity and intensity of delusional beliefs is crucial for clinical evaluation.

    Observation:

    • A novel 'personal questionnaire' method was developed to operationalize the concepts of delusion fixity and intensity.
    • This method was piloted on two patients to measure the fixity and intensity of their beliefs.
    • The pilot study successfully collected and reported data on these belief characteristics.

    Findings:

    • The personal questionnaire method provides a quantifiable approach to assessing delusion characteristics.

  • Pilot data suggest the method is capable of differentiating levels of fixity and intensity in delusional beliefs.
  • This operationalization aids in moving beyond qualitative descriptions of delusions.

    • Implications:

    • The proposed method offers a standardized tool for research and clinical practice in psychiatry.
    • Improved measurement of delusions can lead to more targeted and effective treatment strategies.
    • This work contributes to a more empirical and evidence-based understanding of psychotic experiences.
