This chapter advances IT ethics research by surveying the literature regarding IT ethical behavior models and proposes an IT ethical behavioral model for further research. A proposed conceptual ethical behavior model is based on an initial meta-analysis of most of the ethical research. The proposed model suggests that ethical behavioral intention is influenced by an individual’s attitude (which in turn is influenced by a variety of other factors such as perceived importance of the issue, consequences of the action, and beliefs), as well as other elements from the Theory of Planned Behavior, equity theory, the environment, control, norms, past ethical behavior, and individual characteristics. This proposed model provides a basis for additional research that should foster a better understanding regarding ethical/unethical behavior and determinants of that behavior. Results from further research in ethical behavior will provide a better understanding of unethical behavior and inappropriate acts allowing organizations to develop realistic training programs for IT professionals, users, and managers as well as incorporate effective deterrent and preventive measures that can curb the rising tide of undesired misuse and unethical behavior in the IT arena.
