Which of the following is NOT a cause of Post-traumatic Stress Disorder (PTSD)?

The experience of witnessing a nature documentary does not typically evoke the intense fear, helplessness, or horror that are hallmark responses to traumatic events, which are necessary for the development of Post-traumatic Stress Disorder (PTSD). PTSD is specifically associated with experiencing or witnessing events that are life-threatening or that cause serious injury or sexual violence.

Traumatic childbirth experiences, being in war zones, and experiencing natural disasters are all recognized as potential causes of PTSD because these events have the capacity to induce significant psychological distress and trauma. Childbirth can be traumatic due to medical complications or physical injuries. War zones expose individuals to violence and life-threatening situations, while natural disasters can lead to loss, injury, and extreme danger. Each of these scenarios can trigger the symptoms of PTSD as they involve encountering extreme stress that overwhelms a person's ability to cope, contrasting sharply with the benign nature of a documentary.
