Generalizability theory (GT), an approach to estimating measurement dependability, offers researchers the ability to assess comprehensively various sources of measurement error simultaneously. Application of GT identifies the conditions that contribute most substantially to error and offers remedies to enhance dependability. A review of GT is presented and a practical application discussed. Researchers who develop instruments or plan studies using observation or questionnaires will appreciate the advantages offered by GT.
概化理论（GT）是一种估计测量可靠性的方法，它使研究人员能够同时全面评估测量误差的各种来源。GT的应用可以识别对误差影响最大的条件，并提供提高可靠性的补救措施。本文将对GT进行综述，并讨论其实际应用。开发测量工具或计划使用观察法或问卷调查法进行研究的人员将认识到GT所带来的优势。
