Now-a-days, there is so many “Prakruti” (Individual Personality) assessment tools are available on online sources, but this tool which is originally developed by Professor Kishor patwardhan and his team is a very simple questionnaire through which one can easily assess his/her own personality without any difficulty. This Questionnaire is designed on the basis of the explanation found in Charak Samhita. This explanation is, in turn based on the specific attributes of a particular Dosha. Charak Samhita explains the specific attributes of a particular Dosha along with the description of the specific features these attributes produces in an individual. Thus, Vata, Pitta and Kapha have been assigned with eight, five and twelve attributes respectively. Furthermore each attribute produces one or more observable features at the physical, physiological, or psychological domains. This Questionnaire designed in such a way that, each feature as described in Charak Samhita has been converted into Question/Statement to form a validated self assessment tool. This tool has simple questions or statements that reflect each trait/feature as described in Charak Samhita alongside the specific attribute of a given Dosha. The respondents were asked to record their agreement or disagreement with the statement/question in the form of “Yes” or “No”. The scores to be allowed for a particular type of response were specified against the statement in a separate column. It was clearly mentioned that if the response of the individual was not the one mentioned in the column, the score to be allotted was Zero. For the sake of the convenience in the calculation, researcher allotted a total of 120 scores for each Guna. If a particular Guna produced a single feature, a full of 120 scores were allotted to that feature, when found in the individual. On the other hand, if a Guna produced more than one feature, 120 scores were divided equally into the specific number of features that the particular Guna produced. For example, if a particular Guna produced four features, 120 scores were divided by four, resulting 30 scores for each feature. Thus, the final maximal scores according to this questionnaire were 960 for Vata, 600 for Pitta and 1440 for Kapha. After submitting their response one can automatically come to know his/her own personality and related Diet-regimen for that particular individual unique personality.
