The Essential Properties of Yoga Questionnaire (EPYQ) is being
designed to address current limitations in the yoga literature and to
advance yoga-related research. The measure developed in this project
will allow users to rate the levels of various dimensions or components
of yoga interventions. The measure will be appropriate for use by
objective raters, teachers, and students. In addition, we foresee the
EPYQ to be useful to those conducting other complementary and
alternative medicine (CAM) interventions.
San Diego is one of 3 study sites across the U.S. working in
collaboration to develop the EPYQ. The overall study comprises 4 phases
designed to systematically develop and test a reliable, valid and
useful quantitative measure of the components and dimensions of yoga.
Each phase builds upon the previous phase. Phase I aims to gain a
comprehensive understanding of the relevant aspects of yoga therapy and
develop a large pool of potential questionnaire items by conducting a
thorough literature review and focus groups with yoga teachers and
students. These data will be analyzed using rigorous qualitative
methods to identify key conceptual dimensions associated with yoga
interventions. Phase II will develop a prototypic questionnaire to
assess yoga therapy by refining and honing information from Phase I and
conducting cognitive interviews to further develop this instrument.
Phase III will pilot test the measure in groups of yoga students and use
factor analysis and item response theory to select the best items per
dimension and to reduce the number of items in the measure. Phase IV
will collect data using the new instrument and test the psychometric
properties of the questionnaire.
