Prof. Cho Eun-Seong (School of Business Administration) To Publish a Thesis on Psychological Methods, the Best Journal in the Field of Research Methodology

Professor Cho re-analyses the existing simulations in his thesis to draw a clear conclusion about which reliability coefficient is the most accurate. This paper has been of interest because it provides a reinterpretation of famous papers. There are two papers that draw different conclusions from the same data, but it is not clear which of the two is correct. This paper argues that both interpretations are inaccurate, suggests a third interpretation, and refutes the mainstream views so far. Most of the existing studies claim that factor analysis-based reliability coefficients are more accurate, but Professor Cho suggests that the factor analysis approach is not superior to other approaches and explains why.
