Objectives: This study is a preliminary investigation aimed at developing and standardizing a tool for assessing discourse comprehension in the elderly. The focus was on establishing the initial reliability and validity of 37 newly developed items as a foundational step for full-scale standardization. Methods: A set of 37 test items, developed through a systematic content validity process, was administered to a preliminary sample of 30 elderly individuals (aged 65+) in Sejong and Jeonbuk regions. Internal consistency (Cronbach’s α), test-retest reliability, and criterion validity with the KOSECT were analyzed. Results: The total Cronbach’s α was high at .876, and test-retest reliability was .993 (p<.001). Criterion validity showed a significant correlation (r=.797). Conclusions: The tool demonstrates strong psycho metric properties. While limited by sample size, this study provides a crucial academic foundation for future large-scale standardization and clinical applications in cogni tive-communication interventions.
