摘要：evaluation tool and guideline for Thai population age range 15-65 years old using psychometricproperty evaluation. The collecting valid and reliable PA information will be relevant to Thai populationwhere patterns of energy expenditure differ from other countries since they experience diverse ways oflife. This descriptive cross-sectional research consisted of two phases: Phase I: Questionnairedevelopment consisted of three steps: 1) translated and back translated instruments to explanation ofthe procedures used for determining the equivalence Thai version of the IPAQ short form 2) contentvalidity, and 3) face validity. Phase II: Psychometric property evaluation used Pearson’s correlationcoefficient to analyze the concurrent validity, and test-retest reliability. The finding showed interrateragreement and the item-level for content validity index (I-CVIs) of the questionnaire were 8.5 และ 86.,respectively. There were little comments after face validity was conducted. The concurrent validitycoefficient was obtained by examining a relationship between the translated IPAQ and accelerometer (r= .32, p = .01). The 7-day test-retest reliability coefficient of the translated IPAQ indicated a very goodreliability of .92. This study demonstrated that the Thai version of the IPAQ short form is relatively suitable and creditable for administration, although the concurrent validity presented a modestcoefficient in which similar to that in other western countries.
