Final answer:
When handling a request for information related to psychotherapy, one should refer the request to a supervisor to ensure confidentiality, privacy, and informed consent are maintained.
Step-by-step explanation:
When a request for information related to any aspect of psychotherapy is made, it is crucial to handle it with utmost care, respecting the patient's privacy and confidentiality. One should refer to protocols that preserve confidentiality, protect subjects from personal harm, and ensure that any information shared is done so with informed consent. While option 1 (providing the requested information) may seem straightforward, it is not advisable to share any information without ensuring that all legal and ethical guidelines are met.
Therefore, the appropriate response would be option 3: refer the request to a supervisor. This ensures that responses are given by a qualified individual who can navigate the legal and ethical complexities, potentially after seeking more details if necessary, while upholding the rights and privacy of the therapy client.
