Internal consistency models for the PSQ hierarchical bi-factor structure.

R = Reliability; GFI = Goodness of Fit Index; RSMR = Root Mean Square of the Standardized Residuals; AGFI = Adjusted Goodness of Fit Index; NFI = Normed Fit Index; RFI = Relative Fit Index.R = 信度（Reliability）；GFI = 拟合优度指数（Goodness of Fit Index）；RSMR = 标准化残差均方根（Root Mean Square of the Standardized Residuals）；AGFI = 调整拟合优度指数（Adjusted Goodness of Fit Index）；NFI = 规范拟合指数（Normed Fit Index）；RFI = 相对拟合指数（Relative Fit Index）。
