The relationships between the WPDSE and the AWPD indicated that all of the variables were significantly positively correlated with each other (all r > 0.
By and large, the teachers' scores on the interaction self-efficacy scale and applying self-efficacy were fairly highly correlated with all of the scales of the AWPD, with the exception of the correlation between applying self-efficacy and anxiety.
Applying self-efficacy was also a significantly positive predictor of the perceived usefulness, ease of use, affection, and behavior of the AWPD.
However, general self-efficacy can only predict affection and anxiety for AWPD.
The WPDSE and the AWPD administered in this study are deemed to be sufficiently reliable for assessing teachers' self-efficacy and their attitudes toward web-based professional development, respectively.
