What influences IT ethical behavior intentions - Planned behavior, reasoned action, perceived importance, or individual characteristics?

This study extends IT ethics research by proposing an IT ethical behavioral model that includes attitude, perceived importance, subjective norms, situational factors, and individual characteristics. The proposed model integrates elements from the Theory of Planned Behavior (TPB) and Theory of Reasoned Action (TRA) as well as ethical decision-making models. It is hypothesized that behavioral intention is influenced by an individual's attitude (which in turn is influenced by consequences of the action and the environment), obligation, and personal characteristics. The results of the study show that some factors are consistently significant in affecting attitude and behavioral intention. Other factors are significant only in certain scenarios. From the results, organizations may be able to develop realistic training programs for IT professionals and managers and incorporate deterrent and preventive measures that can curb the rising tide of undesired misuse.
