“…PGD has been differentiated from Post-Traumatic Stress Disorder (PTSD) and post-loss depression (Boelen & Van Den Bout, 2005; Bonanno et al, 2007; Lichtenthal, Cruess, & Prigerson, 2004). It is referred to as Persistent Complex Bereavement Disorder under the section on conditions for further study in the DSM-5 (American Psychological Association, 2013), and will be introduced as a mental health diagnosis in the ICD-11 (World Health Organization, 2018; Maciejewski, Maercker, Boelen, & Prigerson, 2016). PGD also predicts a host of additional health problems, including heart disease, high blood pressure, cancer (Prigerson et al, 1997; Prigerson, Vanderwerker, & Maciejewski, 2008), suicidality (Latham & Prigerson, 2004), substance abuse, depression, anxiety, and overall life disruption (Boelen & Prigerson, 2007; Ott, 2003; Shear et al, 2011).…”
