共同方法偏差(Common Method Bias)的控制方法分为程序控制(Procedural)和统计控制(Statistical)。 程序控制 程序控制指的是研究者在研究设计与测量过程中所采取的控制措施,比如从不同来源测量预测与校标变量,对测量进行时间上、空间上、心理上、方法上的分离,保护反应者的匿名性、减小对项目目的的猜度,平衡项目的顺序效...
共同方法偏差(Common Method Biases)指的是因为同样的数据或评分者、同样的测量环境、项目语境以及项目本身特征所造成的预测变量与校标变量之间人为的共变(周浩, 龙立荣, 2004)。 测量误差包括系统误差和随机误差。共同方法偏差是一种系统误差。 来源 1. 同一数据来源或评分者 产生这种现象的机制包括: 一致性动机(Con...
共同方法偏差的控制与检验在SPSS&Mplus中显得尤为重要。主要分为程序控制和统计控制两个阶段。程序控制是通过研究设计和测量手段来直接减少偏差，如使用多源数据、时间、空间或心理上的分离，保护匿名性，以及优化量表设计等。当程序控制难以实施时，统计控制便发挥作用，如Harman单因素检验和潜在误差变量控制法...
engage in “timed intercourse”28, sexual activity during the ovulation period to increase conception chances. This method may partially reduce the stress of sex life in PL couples. It may not ultimately be beneficial for accelerating pregnancy, but may increase the risk of sexual dysfunction29. D...
By running a bootstrapped PCA (i.e., 1000 random resamples) with a program syntax for SPSS101, we further confirmed the number of factors to retain, stability and replicability of the component structure (see41). We calculated PCA component scores with a regression method (see42 and ESM ...
These statistical analyses were performed using the Statistical Package for the Social Sciences (SPSS). 2.5.2. Voxel-based morphometry analysis A one-way ANOVA, calculated using SPM12, was used to detect differences in the GMV across the MDD, BD, and HC groups with age, gender, years of ...
Statistical analysis was performed by the SPSS program, version 9. Before comparison of subgroups of G197del carriers according to country of residence, PLPs were adjusted for sex and age, by linear multiple-regression analysis. The allele distribution for ApoE and SR-BI polymorphisms was determine...
All remaining data were analysed using Statistical Package for the Social Sciences (SPSS) Version 19. Results Demographics and medical information Of the 1707 patients we approached to participate during the recruitment period, 1196 (71%) provided baseline data (see Figure 1–recruitment diagram). ...
Statistical analyses were performed applying STATA version 14.0 (StataCorp, College Station, TX, USA) and SPSS version 25.0 (IBM, Armonk, NY, USA). The RR and 95% CI were established as overall effect sizes in this work, similar to effect estimates reported in observational articles meeting ...
Statistical analysis was performed with statistical software package SPSS® Version 24 (IBM, Armonk, North Castle, New York, USA). Compression forces were compared using one-way analysis of variance (ANOVA) followed by post hoc tests with Bonferroni correction for multiple testing. The non-destruc...
