Explain 'capacity' versus 'competence' and how this applies to consent in psychiatric care.

• A. Capacity is a patient’s general ability to make any decision, and competence is a legal outcome.
• B. Capacity is decision-specific and time-specific; competence is a legal determination.
• C. Capacity and competence are interchangeable.
• D. Competence is decision-specific.

Answer: (B)

The important idea here is that ability to participate in decisions about treatment is not all-or-nothing or global. Capacity means you can understand the information about a specific plan, appreciate how it applies to you, reason about the options, and communicate a choice for that particular decision at that time. It can vary from one decision to another and can change over time.

Competence, by contrast, is a legal status determined by a court. It’s a broad judgment about whether a person generally has the capacity to handle affairs or make decisions, and it can lead to surrogate decision-makers or guardianship if found lacking.

In consent for psychiatric care, you assess capacity for the specific treatment being offered, at the moment you seek consent. If the patient demonstrates understanding, appreciation, reasoning, and ability to communicate a choice about that treatment, their consent is valid. If they lack capacity for that decision, a legally authorized representative may consent on their behalf, and in some settings, emergency provisions or guardianship mechanisms may apply. Remember, capacity can fluctuate and may improve with information or support, and it does not automatically imply a lack of capacity in other areas.
