***p<0.001
As shown in Table 3, reliability and convergence validity analysis, dimensions, all items, and standardized estimation coefficients are all greater than 0.6. The significance estimate is divided by the standard error to obtain the Z value (Est./SE) of the significance estimate. Z value>0.96 means significant, and all p values<0.001, which means that all items are significant. The item reliability is the square of the standardized estimated value. The R-square of the item is above 0.36 means acceptable, and above 0.5 means good. Item reliability (Square multiple correlations, SMC or R-square: the square of the standardized factor loading) refers to the explanatory ability of the dimension to the items, composite reliability is the internal consistency of the dimension topic, and AVE refers to the dimension to the items. The average explanatory ability of AVE is greater than 0.5, indicating that the dimension has a good explanatory ability, and the value of AVE was above 0.36 means acceptable. The convergence validity of all dimensional items reached the recommended level. Diagonal bold values are the root sign value of AVE, and the lower triangle is the Pearson correlation between the dimension according to the output table of Tech 4 in Mplus 8.3.
