Understanding PTSD and Resilience

Understanding PTSD and resilience helps clarify how individuals respond differently to trauma and why recovery is not a linear process.

What we know...​

• What is resilience?

Resilience does not mean the absence of distress. Rather, it refers to an individual’s ability to adapt, cope, and continue functioning in the presence of adversity. A person may demonstrate resilience in one situation while experiencing significant difficulty in another. This variability is a normal human response, not a failure. An individual may display resilience to one traumatic event, while developing symptoms of post-traumatic stress to another (Damiani & Vaillant, 2003). 

• What is a traumatic event?  

A traumatic event is generally defined as an experience involving actual or threatened death, serious injury, or sexual violence, whether directly experienced, witnessed, or learned about. An event is considered traumatic if the person experienced, witnessed, or was confronted with an event or events that involved actual or threatened death, serious injury, or sexual violence (American Psychiatric Association [APA], 2013). 

​

• What is posttraumatic stress disorder (PTSD)?

Post-traumatic stress disorder (PTSD) is diagnosed by qualified medical professionals. It may involve patterns such as intrusive memories, avoidance of reminders, changes in mood or beliefs, and heightened arousal or vigilance. Not everyone who experiences trauma develops PTSD.

• Is Trauma Common?

Traumatic experiences are more common than many people realize. Loss, violence, accidents, and other distressing events affect individuals across all backgrounds. Experiencing trauma does not imply weakness, nor does it determine how someone will respond over time.

• Why Do Responses Differ?

People respond differently to trauma based on many factors, including prior experiences, available support, personal coping strategies, and the nature of the event itself. There is no single explanation that applies to everyone, and comparison between individuals is rarely helpful.
