Which of the following events is most likely to result in post-traumatic stress disorder (PTSD)?
**Core Concept**
Post-traumatic stress disorder (PTSD) is a complex psychological condition that develops in response to a traumatic event, characterized by symptoms of anxiety, depression, and avoidance of reminders of the trauma. The underlying concept being tested is the relationship between traumatic exposure and the development of PTSD.
**Why the Correct Answer is Right**
The correct answer is related to the concept of "loss of control" during the traumatic event. When an individual experiences a traumatic event and feels a loss of control, it can lead to a heightened sense of vulnerability and fear, increasing the likelihood of developing PTSD. This is because the brain's stress response system, including the hypothalamic-pituitary-adrenal (HPA) axis, is activated in response to the perceived threat, leading to the release of stress hormones such as cortisol and adrenaline. The repeated activation of the HPA axis can result in long-term changes to the brain's structure and function, contributing to the development of PTSD.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not directly related to the development of PTSD. While physical injury can be a consequence of a traumatic event, it is not a primary factor in the development of PTSD.
**Option B:** Dissociation is a common response to traumatic events, but it is not the most likely event to result in PTSD. Dissociation can be a coping mechanism that helps individuals detach from the traumatic experience, but it does not necessarily lead to the development of PTSD.
**Option C:** This option is not directly related to the development of PTSD. While social support can be an important factor in recovery from traumatic events, it is not a primary factor in the development of PTSD.
**Clinical Pearl / High-Yield Fact**
One memorable point to remember is that the development of PTSD is not solely dependent on the severity or type of traumatic event, but rather on the individual's subjective experience of the event and their perceived loss of control.
**Correct Answer: C.**
