建立中文版鴉片類藥物成癮治療成效量表—信度與效度研究

The Reliability and Validity of the Modifi ed Chinese Version of the Opiate Treatment Index

目的：此研究的目的是將鴉片治療指數翻譯成中文並評估其效度、測驗－－再測驗信度與評估者間信度。方法：本研究在某療養院進行。使用單一測驗－－再測驗信度個案群體來檢驗此量表的測驗－－再測驗信度及評估者間信度。共有25病人由兩位評估者進行評估。使用Cronbach’salpha值來評估連續變項的信度。結果：測驗－－再測驗信度部分，Cronbach’salpha值在0.587到0.972之間。評估者間信度部分，Cronbach’salpha值在0.666-0.963之間。結論：結果顯示中文版之鴉片治療指數整體而言有良好的信度。部分分測驗之信度不佳可能是與題目探詢個案之敏感問題，例如犯罪與性生活。

Objectives: The purpose of this study was to assess the validity, test-retest and inter-rater reliability of a Chinese version of Opiate Treatment Index. Methods: A test-retest single group design was used to investigate the test-retest and inter-rater reliability of the scale. Two raters conducted each measure twice on a total of 25 subjects. This study was conducted in the mental hospital setting. Cronbach’s alpha values were used to assess reliability of continuous variables. Results: Cronbach’s alpha value results ranged from 0.587 to 0.972 for test-retest reliability. The Cronbach’s alpha value of the total OTI scale for inter-rater reliability was 0.666-0.963. Conclusion: Many of the clinical measures demonstrated good overall inter-rater and test-retest reliability. Those tests where acceptable test-retest and inter-rater reliability cannot be demonstrated. This fi nding may be due to sensitive material involving the topics of sexual and criminal behaviors.
