Which of the following symptoms is commonly associated with acute stress disorder?

The selection of flashbacks related to the traumatic event as a symptom commonly associated with acute stress disorder is accurate because flashbacks are a hallmark feature of this condition. Acute stress disorder typically arises in response to a traumatic experience and can occur soon after the trauma, manifesting within a few days to month after the incident. During this period, individuals may relive the trauma through unwanted and intrusive flashbacks, which can significantly impact their day-to-day functioning and emotional state.

This symptom reflects the re-experiencing of the trauma, a core component of both acute stress disorder and post-traumatic stress disorder (PTSD), though the timeline and duration of symptoms may differ. The occurrence of flashbacks can elicit heightened anxiety, distress, and a feeling of losing control, aligning with the acute symptoms observed in individuals navigating this disorder.

The other symptoms listed do not align as closely with acute stress disorder. Persistent hallucinations, chronic avoidance behavior, and severe depression lasting for years typically characterize different mental health conditions or chronic stress responses, rather than the immediate and acute reactions specific to acute stress disorder. Thus, while they may be present in various contexts, they do not define the acute nature of the condition in the same way that flashbacks do.
