What type of claims about treatment results are prohibited?

The answer choice focusing on misleading claims reflects a critical aspect of ethical practice in psychology. The prohibition against misleading claims is grounded in the necessity for transparency, honesty, and integrity in the therapeutic relationship and in advertising services. Misleading claims can create false expectations about the effectiveness of treatments, potentially placing clients at risk.

Informed consent and clients' understanding of treatment outcomes are paramount, and any statement that could deceive a client about the probability of success or the nature of therapy may violate ethical standards and regulations. Therefore, psychologists must ensure that their communications clearly represent the nature and results of their services, thereby fostering trust and maintaining professional integrity.

While exaggerated and vague claims can also be problematic, misleading claims have a more direct impact on clients' decision-making processes and can lead to significant misunderstandings about what they can reasonably expect from treatment. Honest claims, on the other hand, are not prohibited and should be encouraged as part of ethical practice.
