External regulation is best described as being motivated to change to satisfy an external demand.

• A. External regulation
• B. Introjected regulation
• C. Identified regulation
• D. Integrated regulation

Answer: (A)

In Self-Determination Theory, external regulation is a form of extrinsic motivation driven by outside pressures, rewards, or punishments. The behavior is undertaken primarily to satisfy an external demand, not because the person personally values the task or enjoys it. This is why the description fits best: changing one’s behavior to meet an outside expectation.

For contrast, introjected regulation involves internal pressures like guilt or ego; identified regulation means the person values the outcome and sees it as personally important; and integrated regulation is fully aligned with one’s identity and values. External regulation stands out as being motivated by external demands rather than internal justification.
