Abstract：
UNASSIGNED: Epidemiological studies suggest that nyaope, a heroin-based drug, is widely used in South Africa. Yet few reliable research tools are available to assess treatment outcomes of users. The Opiate Treatment Index (OTI), a tool developed in Australia, could potentially facilitate research on context-specific South African treatment outcomes. However, we know little of its test-retest reliability.
UNASSIGNED: This study aimed to assess the test-retest reliability of the OTI among a sample of nyaope users in Johannesburg.
UNASSIGNED: This study was conducted across three substance use treatment facilities in Johannesburg.
UNASSIGNED: The OTI was administered to 53 nyaope users at baseline and one week later. To determine the test-retest reliability of the OTI, the intra-class correlation coefficients (ICC) and the Brennan-Prediger coefficients of the two interviews were calculated.
UNASSIGNED: The ICC of the Q-scores from the data sets along with the Brennan-Prediger coefficient for the substance use domain were calculated. The ICC for nyaope was 0.38. Brennan-Prediger coefficients were as follows: alcohol - 0.96, crack-cocaine - 0.89, cannabis - 0.92, methaqualone - 0.85 and crystal methamphetamine - 0.89.
UNASSIGNED: A significant positive finding was the excellent test-retest reliability of the injecting and sexual behaviour domains and moderate reliability of the criminality, general health and social functioning domains.
UNASSIGNED: The results of this study provide insight into the reliability of this tool and for its use in future studies in the South African context.

摘要：
■流行病学研究表明，Nyaope，一种以海洛因为基础的药物,在南非广泛使用。然而，很少有可靠的研究工具可用于评估用户的治疗结果。阿片类药物治疗指数（OTI），澳大利亚开发的工具，可能有助于研究特定背景的南非治疗结果。然而,我们对它的重测可靠性知之甚少。
■这项研究旨在评估OTI在约翰内斯堡的nyaope用户样本中的重测可靠性。
■这项研究是在约翰内斯堡的三个物质使用处理设施中进行的。
■在基线和一周后对53名nyaope使用者进行了OTI。为了确定OTI的测试-重测可靠性，计算了两次访谈的类内相关系数（ICC）和Brennan-Prediger系数。
■计算了来自数据集的Q分数的ICC以及物质使用域的Brennan-Prediger系数。nyaope的ICC为0.38。Brennan-Prediger系数如下：酒精-0.96，可卡因-0.89，大麻-0.92，甲喹酮-0.85和甲基安非他明-0.89。
■一个重要的积极发现是注射和性行为领域的出色重测可靠性和犯罪的中等可靠性，一般健康和社会功能领域。
■这项研究的结果为该工具的可靠性及其在南非背景下的未来研究中的使用提供了见解。
