title: Psychometric Properties of the Korean Version of the "Patient Activation Measure 13" (PAM13-K) in Patients With Osteoarthritis.
abstract: This study investigated the psychometric properties of the Korean version of the Patient Activation Measure 13 (PAM13) using Rasch analysis. The sample consisted of 270 Korean patients with osteoarthritis. The PAM13 was translated into Korean using a standardized forward-backward translation approach. In this study, the Cronbach's α coefficient was .88, the average interitem correlation was .34, and the average item-rest correlation was .55. The difficulty ranking of the item in this study differed from that in the original version. We did not need to collapse response categories. A total of 57.5% of the variance was explained by the residuals, indicating unidimensionality. The results suggest that the PAM13-K is a reliable and valid measure of activation. Further research is needed to validate item responsiveness and intervention effects.
