Intention to continue usage	3	.93					0.90

^aThe diagonal (italicized values in the table) refers to the square root of the variance shared by each variable and its respective items. The values off the diagonal refer to the intercorrelations between the variables. The values in the lower part of the table are a mirror of those in the upper part above the diagonal.

^bThe correlation was significant at P<.01.
