摘要
报告北京老龄化多维纵向研究设计及预试验过程中。如何应用 Reliability 分析的几个方法.验证所调查研究项目的一致性、确切性。以及进行必要修订的体会。实验证明,应用上述方法.尤其是Cronbach 的α系数法。能帮助验证量表研究项目的一致性、确切性,提高科研设计的科学水平.
In the sociological surveys it is extremely important to use “Scales” to quantify those characteristics which seem to be unmeasurable originally.This paper reports on now several methods of relianbility analysis were used in the design and pilot study of “Beijing Multidi- mensional Longitudinal Study”to verify the consistency and accuracy of the items as well as lessons learned.Our tests have proved that above mentioned methods,Especially cronbach method measuring coefficiencies are conducive to verify the consisitency and accuracy of measurments,Thus usefuil to upgrade the scientific level of the research design.
