This study evaluates the ethical criteria lobbyists consider in their professional activities using Ruth Edgett's model for ethically desirable public relations advocacy. Data were collected from self-administered surveys of 222 registered lobbyists in Oregon. A factor analysis reduced 18 ethical criteria to seven underlying factors describing lobbyists' ethical approaches to their work. Results indicate that lobbyists consider the following factors in their day-to-day professional activities: situation, strategy, argument, procedure, nature of lobbying, priority, and accuracy. This framework, derived from Edgett's 10 (...) criteria, illustrates the importance of context while incorporating ideas from recognized ethical theories. (shrink)
