Development and validation of the Thai Eating Questionnaire (TEQ)

Kamonporn Patcheep


This paper describes the development and validity assessment of the Thai Eating Questionnaire
(TEQ) to assess the healthiness of Thai adolescents’ eating behavior, based on the Theory of Planned
The TEQ was developed in English according to standard methodology, assessed for content
validity index (CVI) by a panel of experts, translated into Thai and back-translated into English. TEQ was
piloted with 34 Thai adolescents, then repeated one week later to assess test-retest reliability. It was
tested again with 336 Thai adolescents.
The TEQ has very good content validity (CVI 0.980), acceptable internal consistency (Cronbach’s
alpha 0.870 and 0.853 with small and large group) and high test-retest reliability (0.900)
The TEQ appears to be a valid and reliable instrument suitable for use in further studies of
Thai adolescents from both urban and rural areas in Thailand.
