What is the major difference between posttraumatic stress disorder (PTSD) and acute stress disorder?

Choice A reason: PTSD does not have a recovery rate of 80% within three months. This statement is inaccurate and misleading. Choice B reason: Severity and duration of trauma influence both acute stress disorder and PTSD. This is not a distinguishing factor between the two conditions. Choice C reason: Acute stress disorder does not necessarily lead to exacerbation of symptoms. Many clients recover without progression to PTSD. This statement is incorrect. Choice D reason: PTSD is diagnosed when symptoms persist for more than one month and often continue for three months or longer after trauma. Acute stress disorder occurs within the first month post-trauma. This distinction makes D the correct answer.
