4 core elements when assessing capacity to consent: which is the fourth core element?

• A. Understanding
• B. Appreciation
• C. Reasoning
• D. Communicating

Answer: (D)

The ability to consent rests on four distinct abilities: understanding the information about the treatment, appreciating how that information applies to one’s own situation, reasoning about options and consequences, and communicating a clear decision. The fourth element is communicating. Even if someone understands the details, recognizes how it affects them, and weighs the options, they still need to be able to express a choice. This communication can be verbal, written, or through another reliable means. If a person cannot convey a decision, their capacity to consent is not complete, because the choice isn’t being stated back to the clinician. So, communicating is the final piece that completes the ability to consent.
