Is it ethical for a psychologist to engage in a sexual relationship with a student after the course has been completed?

The choice emphasizing that it is unethical for a psychologist to engage in a sexual relationship with a student even after the course has been completed is correct because it highlights the ongoing potential for evaluative authority. This authority can create an imbalance in the relationship, making it susceptible to exploitation or conflict of interest. The ethical guidelines for psychologists stress the importance of maintaining professional boundaries and avoiding situations where power dynamics could lead to unethical outcomes.

Relationships that arise immediately after evaluative relationships—such as those involving students—are particularly scrutinized because the inherent power difference may still impact the dynamics, even if formal grades have been submitted. The ethical standards are concerned with preserving the integrity of the profession and protecting the welfare of students and clients. These standards are designed to prevent abuse of power and ensure that all professional interactions remain respectful and appropriate.

In this context, the other options either simplify the complexities of power dynamics or suggest that the completion of a course removes any ongoing responsibility to maintain professional boundaries. However, the ethical implications are more nuanced, and maintaining professionalism is essential, reinforcing the reasoning for why the correct response emphasizes the ongoing evaluative authority and the need for ethical vigilance.
