Examining trying as a mediator and control as a moderator of intention–behavior relationship

This article presents a modified model of the theory of planned behavior by incorporating trying as a mediator and actual control as a moderator of the intention–behavior relationship. The revised model was tested with the use of structural equation models for eight commonly performed activities (N = 240). Results provide general support for the model suggesting that intentions influenced the level of trying, which, in turn, influenced behavior. Correlation analysis employing Fisher's z transformation revealed that actual control moderated the relationship between trying and behavior. Implications of the findings are discussed. © 1998 John Wiley & Sons, Inc.
