Sun-Yuan Chou, Hung-Yu Chan

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.
