The SPQ (Sasang Personality Questionnaire) is developed for the assessment of personality based on the Sasang typology, and this 14-item SPQ has three sub-scales including SPQ-behavior, SPQ-emotionality, and SPQ-cognition (1).
It's clinical validity (2) and usefulness (3) were confirmed repeatedly.  The interesting thing is that the SPQ, rather than BMI, can predict some part of general health status (4).  

It was reported that the SPQ and Body Mass Index is a objective measures of biopsychological characteristics of Sasang typology in general population with consideration of age and gender (3).
