Background and purpose: With advancements in technology, computer use is be- coming 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 re- liability (.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. |
