The sufficiency economy philosophy in King Bhumibol’s initiative is a principle for the development of people especially their ideas and the relationship of adequate living, that is providing guidance on appropriate conduct covering numerous aspects of life. This construct is a new model in educational measurement in Thailand. This study tried to examine the construct validity of the measurement model by using the sufficient life skill (SLS) scale. The scale was used to measure the SLS of 599 Thai students studying in basic education level and the lie scale was applied to detect faking of test takers. The confirmatory factor analysis was utilised for comparing the two different models, holistic and specific models. The result showed consequence of construct validity of the better model. In addition, findings also supported the importance of applying lie scale for detecting faking responses. Theoretical implications are discussed.

Keywords: Construct validity, confirmatory factor analysis, sufficient life skill, sufficiency economy philosophy.
