Step 1: Understanding the Concept:
PTSD is an anxiety disorder that can develop after a person is exposed to a traumatic event, such as warfare, sexual assault, a natural disaster, or a serious accident. The name of the disorder describes its key features.
Step 2: Detailed Explanation:
Let's break down the acronym:
P - Post: Means "after," indicating the disorder develops after the event.
T - Traumatic: Refers to the nature of the causal event.
S - Stress: Describes the psychological and physiological response.
D - Disorder: Indicates it is a clinically recognized condition.
Combining these gives Post Traumatic Stress Disorder. The other options use incorrect terms like "Pre" (meaning before) or "Situational" instead of "Stress".
Step 3: Final Answer:
The full form of PTSD is Post Traumatic Stress Disorder.
