An exploration of affect factors and their role in user technology acceptance: Mediation and causality

Heshan Sun, Ping Zhang
2008 Journal of the American Society for Information Science and Technology  
Results from this research indicate that a PE→PEOU causal direction is favored, and PEOU partially mediates PE's impacts on PU whereas PE fully mediates CP's impact on PEOU.  ...  With the increased interest in various affect factors in user technology acceptance and use, our study sheds light on the role of affect factors from both theoretical and methodological perspectives.  ...  For instance, examining search results, which also is a part of using search engines, can be fun and can influence users' acceptance of search engines.  ...
