Which of the following actions are grounds for prosecuting a psychologist?

The grounds for prosecuting a psychologist involve a clear violation of laws or regulations that are designed to protect clients and ensure the integrity of psychological practice. Failing to perform required duties according to the Child Protective Services Law represents a serious neglect of responsibility that could jeopardize the welfare of a child. Psychologists have a mandated duty to report suspected child abuse or neglect, and neglecting this duty can lead to legal consequences, including prosecution. This is particularly relevant in Pennsylvania, where the Child Protective Services Law sets forth specific obligations for reporting.

In contrast, the other actions listed do not typically warrant prosecution. Disagreeing with a colleague's approach to therapy reflects professional differences in practice and does not breach legal or ethical standards. Using outdated therapy methods, while potentially concerning from an ethical or best-practice standpoint, does not necessarily constitute legal grounds for prosecution unless it can be shown to cause harm or violate regulatory standards. Taking longer than expected to complete a session is often a matter of clinical judgment and practice management rather than a legal issue. Therefore, the only option that aligns with prosecutable offenses is the failure to adhere to mandatory reporting laws concerning child welfare.
