摘要： 追踪研究中测验工具的信度是衡量追踪研究质量的重要指标。传统的信度估计方法不适用于估计追踪研究的测验信度。近年来, 研究者提出了四种估计追踪研究的测验信度, 包括估计单个时间点的测验信度系数rw和r(Sw), 以及估计整个追踪研究的测验信度系数RT和RL。本文评述了这四种信度估计方法的数学模型、前提假设及其优缺点。RT和RL既可估计追踪研究中单个时间点的测验信度, 也可估计追踪研究中整个追踪研究的测验信度, 所需要的前提假设较少, 推荐同时使用RT和RL来估计追踪研究的测验信度。

Abstract: Test reliability of a longitudinal study is an important index in evaluating the quality of the longitudinal study. Conventional methods that estimate test reliability are not appropriate to estimate the test reliability of a longitudinal study. In recent years, four methods for estimating the test reliability of a longitudinal study were proposed. rw and r(Sw) coefficients were designed to estimate the test reliability of a longitudinal study at each wave, whereas RT and RL were designed to estimate the test reliability of the whole longitudinal study. The mathematical models and assumptions of the four reliability coefficients were briefed and their merits and demerits were pointed out in this article. RT and RL were recommended because they can be used to estimate the test reliability of a longitudinal study both at each wave and as the whole under a few assumptions.
