[Purpose] The study purpose was to investigate the test-retest reliability of the Quebec User Evaluation of Satisfaction with assistive Technology 2.0-Korean version (QUEST-K) for individuals with traumatic spinal cord injury. [Subjects and Methods] Seventy participants with spinal cord injury were enrolled in this study. The participants were assessed using the QUEST-K in two sessions conducted 3 days apart. This study also utilized the spinal cord independence measure III and modified Barthel index for determining their validity concurrently with the QUEST-K. [Results] The test-retest reliability (intraclass correlation coefficient 0.855) of the QUEST-K was high, indicating a good agreement. The results of the QUEST-K testing were not substantially positively correlated with those of the spinal cord independence measure III (r = −0.075) and Modified Barthel Index (r=−0.138). [Conclusion] The test-retest reliability of the QUEST-K was high in individuals with spinal cord injury. The QUEST-K could be a reliable measure for evaluating the satisfaction with assistive technology during functional performance in patients with spinal cord injury. The ability of the QUEST-K to detect actual changes is acceptable for research and clinical settings.
