    مصطلحات موضوعية: 正常老化過程伴隨著認知功能的改變,尤其是執行功能與處理速度表現皆下降。路徑描繪測驗(Trail Making Test, TMT)與彩色路徑描繪測驗(Color Trails Test, CTT)被廣泛用於評估執行功能與處理速度。隨著全球人口快速老化,發展和更新神經心理測驗的常模資料是必要的,特別是老年人口的常模資料。本研究目的為初步發展台灣中南部地區認知正常老年人TMT和CTT的常模資料,並評估這些測驗的心理計量特性。本研究共收集169位台灣中部及南部地區認知正常老年人常模樣本(包含74名男性和95名女性)。多元回歸分析顯示年齡與教育程度顯著影響TMT和CTT的完成時間表現(年齡和教育程度分別與兩項測驗的完成時間呈現正相關和負相關),質性分數中僅有CTT提示與TMT的B-A差異表現與年齡相關。性別則不影響測驗表現。TMT(TMT-A, rs = .726, TMT-B, rs = .848)和CTT(CTT-1, rs = .808, CTT-2, rs = .820)具有適當再測信度。TMT和CTT分別都與語意關聯語文流利度測驗和修訂版尼爾森卡片分類測驗的表現具有顯著相關,CTT-1完成時間、TMT的B-A差異與CTT提示與語意關聯語文流利度測驗有關。本研究結果顯示,TMT和CTT可能為具信效度且可應用於台灣老年人族群的神經心理衡鑑工具。, Normal aging process can be accompanied by changes in cognitive functions, especially in executive functions and processing speed. The Trail Making Test (TMT) and the Color Trails Test (CTT) are neuropsychological tests that are widely used to assess executive functions and processing speed. With the rapid aging of population globally, it is merited to develop and update normative data of neuropsychological tests, especially the normative data of elderly individuals. In this study, we aimed to develop preliminary normative data of the TMT and the CTT among cognitively normal elderly individuals in central and southern Taiwan and evaluate the psychometric properties of these tests. One hundred and sixty-nine cognitively normal participants (74 male and 95 female) were assessed. Multiple regression analyses revealed significant influences of age and education level on completion time in both the TMT and the CTT (age and educational levels were positively and negatively associated with completion times for both tests, respectively). Among qualitative scores, only the CTT cue score and the difference in completion time between TMT-B and TMT-A (B - A) were associated with age. Gender did not in?uence the test performances. Test-retest reliabilities of TMT (TMT-A, rs = .848) and CTT (CTT-1, rs = .820) were appropriate. Performances on TMT and CTT significantly correlated with performance on the Semantic Association Verbal Fluency (SAVF) and the Modified Card Sorting Test, except for CTT-1 completion time. B - A and CTT cue scores correlated with performance on the SAVF. These results suggested that the TMT and the CTT can be reliable and valid tools for the neuropsychological assessment among elder individuals in Taiwan

    مصطلحات موضوعية: 全球人口老化為現今社會面臨的挑戰,老化可能伴隨認知功能改變,注意力、執行功能、工作記憶、及處理速度為常被報告與老化有關的認知功能改變,時限聽覺序列加法測驗(Paced Auditory Serial Addition Test, PASAT)為一臨床常用於評估上述功能的測驗,然而現行的修訂版PASAT(PASAT-Revised, PASAT-R)常模中高齡者樣本相對有限,故本研究目標發展臺灣健康高齡者的PASAT-R常模並評估測驗在此族群中的心理計量特性。本研究依母群人口結構分層抽樣、招募臺灣各地區166名65歲以上、教育程度0至18年之正常高齡者進行PASAT-R的施測,利用Cronbach’s α檢驗測驗內部一致性,並於三個月後隨機抽取30名參與者進行再測以檢驗再測信度;校標關聯效度利用評估PASAT-R表現與語意聯想口語流利度測驗,魏氏成人智力測驗第三版的算術分測驗、記憶廣度分測驗、符號搜尋分測驗,以及數字符號替代分測驗表現的關聯評估,建構效度利用多元迴歸分析人口學變項與測驗表現關聯評估。結果顯示PASAT-R在台灣老年族群中具有良好內部一致性(α = 0.94)再測信度(r = 0.90);PASAT-R與注意力與執行功能測驗、工作記憶測驗,以及訊息處理速度測驗皆有顯著相關(r = 0.40 ~ 0.79);PASAT-R表現與年齡成反比(b = -.95 ~ -.18)、與教育程度成正比(b = -.95 ~ -.18);本研究在控制人口學變項之影響並教正後,計算出PASAT-R的百分等級表。PASAT-R為一可運用於台灣高齡者工作記憶、注意力、執行功能,以及處理速度評估的神經心理測驗。, Aging of population is a global challenge. Aging can be accompanied by cognitive decline. Changes in attention, executive functions, working memory, and processing speed are the most frequently reported cognitive decline associated with aging in previous researchers. Changes in these cognitive domains are also sensitive to various brain diseases. The Paced Auditory Serial Addition Test (PASAT) is a widely used test assessing these cognitive domains in the clinical settings. However, normative data established for the Revised version of the PASAT (PASAT-R) is constrained in terms of sample size of elderly individuals. This study aimed to assess psychometric properties and to establish normative data of the PASAT-R among elderly individuals in Taiwan. One-hundred and sixty-six individuals over 65 years old were recruited using stratified sampling based on the demographic structures (age, educational level, gender). Internal consistency was assessed by evaluating Cronbach’s α. Test-retest reliability was assessed by evaluating correlation coefficient between performance at first examination and retest 30 days after the first examination. Criterion-related validity was assessed by evaluating the correlation between performance on the PASAT-R and various tests assessing attention, and processing speed, including the Semantic Association of Verbal Fluency, Arithmetic subtest, Digit Span subtest, Symbol Search subtest, and Digit Symbol Coding subtest. Construct validity was assessed by evaluating the relationships of demographic characteristics (i.e., age, gender) and performance on the PASAT-R. Results revealed the PASAT-R demonstrated good internal consistency (Cronbach’s α = .94) and test-retest reliability (r = .90). Performance on the PASAT-R was correlated with performance on the criterion tests (r = 0.40 ~ 0.79). Performance on the PASAT-R was positively and negatively associated with age (b = -.95 ~ -.18) and educational level (b = .48 ~ 2.35), respectively. We provided a formula for the adjustment of the effects of the demographics on the score on PASAT-R and normative data based on the adjusted score. PASAT-R is a reliable and valid test that could be used in the neuropsychological assessment among elderly individuals in Taiwan
