For which of the following reasons can the State Board of Psychology discipline a psychologist?

The State Board of Psychology has the authority to discipline psychologists for various behaviors that undermine professional ethics and standards. Among those reasons, displaying gross incompetence is a significant factor. Gross incompetence refers to a severe lack of knowledge, skill, or judgment that falls below the accepted professional norms, risking harm to clients and compromising the integrity of the profession. This can lead to disciplinary action as it reflects not only on the psychologist's ability to provide adequate care but also on the credibility of the psychology field as a whole.

In contrast, while having advanced degrees in fields outside of psychology may not be a disciplinary concern on its own, it does not directly relate to unethical behavior or professional standards. Splitting fees with an employee might also raise ethical questions, but it doesn't necessarily equate to gross incompetence or professional misconduct warranting discipline on its own. Therefore, the specific focus on gross incompetence provides the most direct and relevant reasoning for the disciplinary actions that the State Board can take against a psychologist.
