一般论文的信效度要求有哪些？

    答：量表信度部分，主要检验个别项目的信度，以多元相关平方(Squared Multiple Correlations, SMC)值作为观察标准值，理想的SMC值需大于0.5，表示测量指标具有良好的信度。潜在变量组成信度(Composite Reliability, CR)：指构面内部变数的一致性，一般而言，其值须大于0.7(Hair et al., 2010)。本研究中之潜在变量的组成信度值皆大于0.9，代表构面具有良好的内部一致性。在收敛效度方面，检验因素负荷量，个别构面的组成信度以及平均变异数萃取量(Hair et al. 2010; Shiau and Luo 2013)。因素负荷量须大于0.7，各测量构面的组成信度的值须大于0.7(CR>0.7)建议值，当所有构面平均变异数萃取量的值均大于建议值门槛0.5(Hair et al. 2010)，则具有其收敛效度。区别效度主要是检验测量变量对于不同构面间的鉴别程度。各构面间平均变异数萃取量的平方根值均需大于测量不同构面间之相关系数(Hair et al., 2010; Shiau and Luo, 2013; Shiau and. Chau, 2016；Shiau et al., 2020.)
