其他摘要：The objective of this research are to develop adversity quotient test for graded 9 students, to check the quality adversity quotient test by item response theory. The sample of study consisted of 700 graded 9 students form the under the Secondary Educational Service Area Office 3 in 2019 academic year. Data were analyzed to IRT Pro program. The results of this research were as follows. 1. The results of the development were adversity quotient test. That AQ test was 40 three-choice items situational four elements based on Stoltz’s theory. The adversity quotient validity was in the range from 0.60-1.00 and discriminative was in the range from 0.25 - 0.65. 2. The results of item response model showed that four elements discrimination parameter (α) range from 0.51 – 2.49 and difficulty parameter (β) showed that β1 range from -2.96 to -1.35, β2 range from -1.60 to 0.45. The test information of adversity quotient test high showed that ability low level.
