本研究之主要目的為 (1) 檢定「台灣版匹茲堡睡眠品質量表」於台灣

癌症病人之信度及效度及 (2) 界定台灣癌症病人睡眠障礙的臨界分。

本研究共收集 205 位包含不同診斷的癌症病人，整體內在一致性 Cron bach''s alpha 為 0.79 ，其中 16 位病人在間隔 20-28 天的 再測信度相關係數 r=0.91 。建構效度是與台灣版安德森症狀量表症狀 強度總分平均之相關、台灣版簡明疲憊量表疲憊程度之相關來檢定，

效標效度的建立是以獨立 t 檢定台灣版匹茲堡睡眠品質量表與 DSM

Ⅳ 睡眠症狀以及與台灣版安德森症狀量表之睡眠混亂強度、 7 天自評

睡眠日誌的相關；鑑別效度的檢定是比較高疲憊和低疲憊的病人其睡

眠品質總得分有無顯著差異 ( 台灣版簡明疲憊量最嚴重疲憊程度 1-4

分輕度， 7-10 分重度 ) 。台灣版匹茲堡睡眠品質量表於台灣癌症病人

的臨界分界定是以受試者作業特徵 ( Receiver-operating characteristic cu

rves) 的曲線圖中界定在 9 分時，會有最佳的敏感性及特異性。整體來

說，台灣版匹茲堡睡眠品質量表是一個具備良好信、效度的工具能使

用在台灣癌症病人用以評估過去一個月的睡眠品質。

Psychometric Evaluation of the Pittsburgh Sleep Quality Index in Taiwanese Cancer Patients

英文摘要



The purpose of this study was to validate the Taiwanese version of the Pitts burgh Sleep Quality Index (PSQI-T) and explore the cutoff point for defini ng sleep disturbance in a sample of 205 Taiwanese patients with multiple d iagnoses of cancer. The internal consistency Cronbach alpha was 0.79. The test-retest reliability was 0.91 over a 20-28 day interval in a sample of 16 p atients. Construct validity was established by correlating the MADSI-T me an scores and BFI-T average fatigue scores. Criterion validity was examine d by examining the relationship between PSQI scores and DSM , and by Ⅳ correlating the item of sleep disturbance of MADSI-T and 7-day sleep log.

Known-group validity was established by comparing BFI-T scores betwee

n patients having low fatigue status and those having high fatigue status (B

FI-T score 1-4 vs.7-10 ).The cutoff point of PSQI-T was established by RO

C curve when limits in 9 can have the best sensitivity and the specificity. R

esult suggests that the PSQI-T is a reliable, valid, and sensitive instrument

for measuring sleep quality among Taiwanese cancer patients.
