DEVELOPMENT OF A PSYCHOLOGICAL RESILIENCE MEASURE FOR THAI HIGH SCHOOL STUDENTS

Abstract

This research aimed to develop and vlidate a resilience measure for Thai high school students. The research was conducted in two phases: 1) synthesizing the components and the indicators, and 2) developing and validating the instrument, Using multi-stage sampling, 2,067 students completed the 5-point rating scale. Construct validity was examined with second-order confirmatory factor analysis (CFA), and item quality was analyzed using item response theory (IRT). Findings revealed that the 10 components of resilience, reviewed content validation by experts (CVR=1.00). The CFA confirmed the measurement model had an excellent fit with the empirical data (Chi-Square=221.086, df=190, p=.0607, CFI=.999, TLI=.998, RMSEA=.009, SRMR=.011). The IRT analysis showed all 37 items had discrimination parameters (a) ranging from 0.638 to 2.584 and well-distributed difficulty parameters (b). It is concluded that this instrument possesses high construct validity and item quality according to psychometric standards, making it a reliable tool for measuring and assessing student resilience.
