Answer only for yourself. Answers remain in this page’s memory without saved drafts or personal-result sharing; no quiz-flow statistics are sent. Refreshing or changing language starts fresh. Use Exit and clear to discard current progress.
For adults, answer only for yourself using usual patterns and experiences you already know. Each item has three published descriptions in a shuffled order. Choose the closest overall description, even if some phrases fit less well; no medical examination, new inspection or change of routine is needed. If unclear, inapplicable or declined, choose unscored. All twenty-one response choices finish the form. Personal counts and percentages require every item to be scored; any unscored response withholds all personal numbers, with no substituted zero or changed denominator. All three complete guides remain open without answers or signup. This working digital edition records choices within a cultural research questionnaire and does not identify a medical constitution.
Preparing the test…
This edition presents the published twenty-one-item Brief Prakriti Inventory in its Ayurvedic research context. English items retain Table 2 wording; Chinese is FermatMind’s working translation. Vata, Pitta and Kapha are nominal option keys, with separate count shares rather than a highest assigned type. The unscored response, private browser interface and full cultural guides are website additions.
Three full public readings explain published BPI-21 option keys, choice shares, worked examples, cultural context and source limits. They contain no personal answers or counts and can be read before answering. They are not highest-count types.
Read what selections mapped to Vata mean within BPI-21, with raw-count arithmetic, a cultural context and the limits of this website edition.
Read what selections mapped to Pitta mean within BPI-21, with raw-count arithmetic, a cultural context and the limits of this website edition.
Read what selections mapped to Kapha mean within BPI-21, with raw-count arithmetic, a cultural context and the limits of this website edition.
No. The complete English bank is the published BPI-21, Table 2, under CC BY 4.0, with FermatMind’s working Chinese. The website adds unscored responses, original guides and a private interface; those additions have not inherited the paper’s validation.
The site reports mapped choices rather than a medical constitution or diagnosis. The source study states that predictive validity for health and clinical outcomes remains untested. No result prescribes diet, herbs, supplements or treatment.
Yes. Unclear, inapplicable or declined items can stay unscored. All twenty-one response choices can finish the form without any personal numbers. No omitted value becomes zero, and every full guide remains available.
The published study randomised nominal option order using REDCap. This browser edition shuffles the three source alternatives for each item at the start while preserving their keys. The separate unscored response stays last. This does not establish equivalent platform validation.
No. All three counts stay visible without a highest type or tie-break. This display does not implement the paper’s extreme-group, dual-dosha or Sama classification strategy, population norms or a probability of health outcomes.
The BPI-21 source bank differs from twelve-question online dosha quizzes and from this site’s original four-element metaphor quiz. Its three alternatives per item are nominal descriptions, not a low-to-high rating scale.
Each of twenty-one scored choices adds one to its mapped dosha and zero to the other two. Display count divided by twenty-one times one hundred, to one decimal. The site adds a separate unscored response; any unscored choice withholds all three personal counts and percentages. There is no renormalisation, highest type, dual-dosha assignment, Sama classification, IRT estimate or clinical judgement.
