Which of the following describes a significant behavioral change often seen in PTSD patients?

Avoidance of specific stimuli is a significant behavioral change commonly observed in patients with Post-Traumatic Stress Disorder (PTSD). This behavior typically manifests as a deliberate effort to evade reminders of the trauma that the individual experienced. Such reminders can include people, places, conversations, or situations that trigger distressing memories or feelings associated with the trauma. This avoidance can severely limit a person’s activities and social interactions, as they may withdraw from situations that remind them of their traumatic experience, reinforcing feelings of isolation and anxiety.

In contrast to this, the other options do not align with the typical behavioral responses seen in PTSD. For instance, increased sociability and heightened interest in new activities are generally not indicative of PTSD; rather, they can represent a shift towards more positive mental health. Obsession with daily routines may be seen in other anxiety disorders but is not a primary symptom of PTSD, where avoidance behaviors are far more characteristic. Understanding these behavior patterns is crucial for identifying and providing appropriate support and interventions for individuals with PTSD.
