“…The proposed items span four primary conceptual domains and consist of (1) separation distress, including persistence of intense yearning, longing, sorrow, emotional pain, and preoccupation with the deceased person; (2) reactive distress and behavior in response to the death, including difficulty accepting the death, difficulty reminiscing about the deceased, and excessive avoidance of loss reminders; (3) disruptions in personal and social identity, including feeling like part of oneself has died with the deceased, which may begin as an acute personal existential crisis and develop over time into persisting impairment; and (4) preoccupation with the circumstances of the death, including distressing recollections of the circumstances of the death evoked by loss reminders (e.g., hearing the name of one's deceased father, or being in the company of his family of origin or friends, evokes distressing recollections of his death). These preoccupations may be especially pronounced when the death occurs under violent, gruesome, or otherwise tragic circumstances (Brown et al, 2008;Cohen, Mannarino, & Staron, 2006;Dillen et al, 2009;Layne et al, 2008;Mannarino & Cohen, 2011).…”
