Traditionally the scales of psychological constructs have been developed using exploratory factor analysis with the factor rotation method for simple structure named Varimax or Promax. In this research, we conducted the investigation of the bifactor structure and rotation for scale development postulated for a single dimension. Using Mplus the internal structures of the twelve subscales of the YG Personality Inventory were independently estimated by following three methods; Maximum Likelihood, Weighted Least Squares, and Weighted Least Square Mean and Variance adjusted. Comparing the estimates among different numbers of factors with Bifactor Geomin orthogonal rotation, implications of the methodology for scale development were discussed.
