The essential features of Adjustment Disorder involves a maladaptive reaction to an identifiable psychosocial stressor (e.g., divorce, loss of a loved one), which occurs within three months of onset of the stressor. Once the stressor has terminated, the symptoms do not persist for more than an additional six months.  The symptoms are clinically significant in that the person experiences marked distress in excess of what would be expected, or there is significant impairment in work, social, or other functioning.
