AGING AND ERRORS OF MEASURMENT

本申请寻求支持调查 年龄与调查指标的可靠性之间的关系。 它建议进行 研究了与这种关系有关的四组问题。 一是 调查测量信度与年龄的关系， 大量的调查措施。 第二，考察 年龄和可靠性的测量问题的主题，以评估 年龄和问题内容之间的相互作用影响信度。 第三，考察问题特征与 年龄的可靠性。 第四，要确定 关于这些关系的哪些结论会受到估计的影响 策略，特别是比较LISREL最大似然估计， 替代最小二乘估计策略，即使用EQS 基于任意分布理论的估计，以及最近开发的 涉及分类变量的结构方程模型的技术， 通过LISCOMP。 为了实现这些目标，要求为中学提供支助， 现有调查数据集的性别分析，包括三波小组 设计，允许误差方差分量的无偏估计 在调查措施。 拟议研究中要分析的数据集 是：（a）1956-58-60年全国选举小组研究（n = 1，132），（B） 1972-74-76年全国选举小组研究（n = 1，320），（c）1980年全国选举小组研究（n = 1，320） 选举小组研究（n = 769），（d）1973年重新采访的子样本 一般社会调查（n = 195），（e）1974年重新访谈的子样本， 一般社会调查（n = 195），以及（f）1984年重新访谈的子样本， 德国国家社会调查（ALLBUS）（n = 154）。 使用这些数据集，拟议的研究将调查 按年龄”、按问题主题和正式 问题的特点。 可靠性估计将在 这些使用几种不同方法的三波研究（LISREL，EQS， 和LISCOMP）估计结构方程模型的参数。

This application seeks support for an investigation of the relationship between age and the reliability of survey measures. It proposes to conduct research on four sets of issues concerned to this relationship. First, to investigate the relation between measurement reliability and age for a large number of survey measures. Second, to examine the relation between age and reliability of measurement by topic of question, in order to assess interactions between age and question content in affecting reliability. Third, to examine the relationship between question characteristics and measurement reliability by age. And fourth, to ascertain the extent to which conclusions about these relationships are affected by estimation strategy, specifically comparing LISREL maximum-likelihood estimation to alternative least-squares estimation strategies, namely using the EQS estimates based on arbitrary-distribution theory, and recently-developed techniques for structural equation models involving categoric variables, via LISCOMP. In order to accomplish these aims, support is requested for the secondary analysis of sex existing survey data sets, involving three-wave panel designs, which permit unbiased estimation of components of error variance in survey measures. The data sets to be analyzed in the proposed research are: (a) the 1956-58-60 National Election Panel Study (n = 1,132), (b) the 1972-74-76 National Election Panel Study (n = 1,320), (c) the 1980 National Election Panel Study (n = 769), (d) the 1973 reinterview subsample of the General Social Survey (n = 195), (e) the 1974 reinterview subsample of the General Social Survey (n = 195), and (f) the 1984 reinterview subsample of the German National Social Survey (the ALLBUS) (n = 154). Using these data sets the proposed research will investigate variation in reliability of measurement by age", by topic of the questions, and formal characteristics of the question. Reliability estimates will be obtained in these three-wave studies using several different approaches (LISREL, EQS, and LISCOMP) to estimating the parameters of structural equation models.
