***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.
