Which of the following constitutes unprofessional conduct by a psychologist?

Neglecting professional duties constitutes unprofessional conduct by a psychologist because it directly undermines the ethical and professional standards expected within the field. Psychologists are responsible for providing care that is attentive and consistent, ensuring that clients receive the necessary support and treatment. Failing to fulfill these obligations can harm clients and erode trust in the therapeutic relationship.

In contrast, offering additional sessions is a proactive approach to addressing clients' needs, and providing referrals to other specialists is often a necessary step in ensuring clients receive comprehensive care. Maintaining a professional distance is crucial in preserving ethical boundaries and fostering a healthy therapist-client dynamic. Therefore, these actions align with professional standards, while neglecting duties does not.
