中文摘要 | 背景和目的:隨著技術的進步,電腦的使用變得無處不在,本研究目的是發展篩選輕度認知損傷之電腦版短期記憶測驗 (CB-STM),並且進行信度及效度的檢驗。 方法:研究樣本包括64位年齡介於60至94歲的老年人,其中有17位輕度阿茲海默型失智症,22位輕度認知障礙症患者和25位健康對照組。 結果:CB-STM具有良好的再測信度(.75)和高度的內部一致性系數(.83-.85)。該測驗對於區分正常老年人,輕度認知功能障礙和輕度失智症患間也具有良好的敏感度和特異度。 結論:切截分數為20分時,能有效區分正常老年人與輕度認知功能障礙,其敏感度為76%,特異度為73%;切截分數為13分時,其敏感度為77%,特異度為77%。 |
英文摘要 | BACKGROUND AND PURPOSE: With advancements in technology, computer use is becoming ubiquitous. The present study developed a computer-based short-term memory (CB-STM) test for screening for mild cognitive impairment (MCI). The study was designed to assess the psychometric properties of the CB-STM test, including temporal reliability and concurrent validity. METHODS: The study sample comprised 69 elderly participants (age: 60–94 years), including 17 patients with mild possible dementia, 22 patients with MCI, and 30 normal controls (NCs). RESULTS: The CB-STM test demonstrated adequate test–retest reliability (.75) and high internal consistency (.83–.85), as well as adequate sensitivity and specificity for differentiating between the NC, MCI, and mild possible dementia groups. CONCLUSIONS: Twenty points in the CB-STM test is suggested to generate sufficient balance sensitivity (76%) and specificity (73%) for differentiating between NCs and patients with MCI, and 13 points is suggested to generate sufficient sensitivity (77%) and specificity (77%) for distinguishing between patients with MCI and those with Alzheimer disease. |
