This study investigated the construct validity of the R-JDI by reanalyzing Tak and Downey's(1988) data with different analyses. Two sets of analyses were conducted to address this issue. First, the confirmatory factor analysis suggested that the original five R-JDI scales were a reasonable fit to the data. A Rasch IRT analysis comparing the Korean item statistics to those from a USA sample indicated a moderate convergence between the two samples. Several items were identified where sample and/or cultural differences led to different estimates of item characteristics.
