This study aimed to develop and assess the reliability of the Korean version of the Psychosocial Impact of Assistive Devices Scale (K-PIADS). Experts and researchers in the field of assistive technology carried out the original PIADS with a rigorous translation process. To this end, comprehensive measures were taken, including preliminary translation, reverse translation, verification, and expert panel review. Forty-eight people who are currently using an assistive technology (AT) device participated in the validation phase of this study. Findings suggested that reliability for a K-PIADS was very high (micro = 0.94). The findings of this study indicated that the result could be applied to psychosocial evaluation related to the quality of life of AT device users with disabilities. Replication studies are warranted to further validate K-PIADS.
