One-hundred and eleven graduate students enrolled in a clinical psychology training program (PsyD) participated in a research study that examined the ethical decision-making processes and factors that have been proposed to influence behavior (Smith, McGuire, Abbott, & Blau, 1991). Using a two-part questionnaire, data regarding the ethical behaviors and decision-making processes of graduate students was obtained. The first section of the questionnaire was designed to identify the behaviors modeled for participants by professional psychologists and colleagues, as well as their perceived ethicality of the behavior. The second section of the questionnaire consisted of four ethical dilemmas that varied according to the relationship of the participant to the person depicted as behaving in an unethical manner. Participants were asked to report what they knew they should do based on the APA ethics code (2002) and what they would actually do in response to the ethical dilemma. Additionally, participants were asked to provide rationales for their decisions in order to provide insight into the factors that influence their decision-making processes. Results indicated that participants were more likely to engage in unethical behaviors that they had observed being committed by others, as well as a bias regarding their interpretation, decisions, and behavioral responses to the ethical infractions depending upon the identity of the perpetrator.
