Background: Our survey amongst practicing Ayurveda doctors had established the need for a standardized Prakriti
assessment tool. We have developed Sushrutha Prakriti Inventory (SPI) based on Ayurvedic concept of personality. Objectives: To standardize Sushrutha Prakriti Inventory (SPI) based on Ayurvedic
concept of personality through scientific methods. Settings and design: The SPI tool that was developed through a pilot
study was administered to 1200 healthy volunteers of different age group of both male and female subjects from multi
centres. Method: The data was collected and subjected to the tests of Reliability, Validity and
Normality. A total of 1200 subjects were taken for the test of validation and 120 subjects for Test – retest Reliability and
120 subjects for expert validation by experienced Ayurveda physicians. Results: Data analysis was done using SPSS-2006
version and there was found to be a strong reliability of the Questionnaire with Pearson correlation score for Vata, Pitta
and Kapha being 0.990, 0.952 and 0.954 respectively; the Pearson correlation score for Vata, Pitta and Kapha for
Physical Check-list being 1.000, 0.996 and 0.999 respectively. With respect to Test – retest reliability scores for Vata, Pitta
and Kapha for Questionnaire is 0.994, 0.975 and 0.976 respectively and 1.000, 0.997 and 0.983 for Vata, Pitta and Kapha
respectively for physical Check-list giving a high rate of reliability. The SPI version with 90+60 quections that evolved after
Content / Consensual validity by 10 experts had Cronbach’s alpha between 0.61 to 0.80. Pearson’s correlations of
Subjective vs. Objective assessment was > 0.95 and Test-retest reliability was>0.95 for all three Prakriti. Conclusion: This
study has yielded a scientifically standardized tool SPI with two parts, SPI- Q with 90 objective questions and SPI- C with
60 subjective Physical questions.
