1Junior Resident, Department of Psychiatry, Department of Psychiatry, (All India Institute of Medical Sciences, New Delhi, 110016).
A new 60-item psychoticism questionnaire was developed and validated. This tool effectively distinguishes between psychotic, neurotic, and normal individuals, offering a reliable measure for psychological assessment.
Area of Science:
- Psychological assessment
- Psychometric instrument development
- Clinical psychology
Background:
- Psychoticism is a complex personality trait associated with various mental health conditions.
- Existing assessment tools may lack sufficient discrimination between different diagnostic groups.
- A need exists for a reliable and valid questionnaire to measure psychoticism.
Purpose of the Study:
- To design and construct a psychometrically sound questionnaire to measure psychoticism.
- To validate the questionnaire by assessing its ability to differentiate between psychotic, neurotic, and normal individuals.
Main Methods:
- Initial item pool of 110 questions based on key constructs (e.g., paranoia, mania).
- Iterative item analysis and deletion based on discrimination between groups (psychotics, neurotics, normals).
- Reliability assessed using Kuder-Richardson formula 20; criterion validity by comparing diagnostic groups.
Main Results:
- An initial 110-item questionnaire was reduced to 70 items after the first tryout.
- Further refinement resulted in a final 60-item psychoticism questionnaire.
- The final instrument demonstrated satisfactory reliability and criterion validity.
Conclusions:
- A 60-item psychoticism questionnaire has been successfully constructed and validated.
- The questionnaire effectively differentiates between individuals with psychotic, neurotic, and normal psychological profiles.
- This tool provides a valuable addition to the assessment of psychoticism in clinical and research settings.
