Lifetime mood symptoms and adult separation anxiety in patients with complicated grief and/or post-traumatic stress disorder: a preliminary report.

A minority of bereaved individuals experiences symptoms of complicated grief (CG) that are associated with significant distress and impairment. CG is currently under consideration for inclusion in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-V) and a major issue is whether or not it can be differentiated from major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). The purpose of this study is to compare the clinical features of CG with those of PTSD and CG+PTSD. A total sample of 116 patients (66 PTSD, 22 CG and 28 CG+PTSD) was recruited. Assessments included: Structured Clinical Interview for DSM-IV Axis-I disorders (SCID-I/P), Inventory of Complicated Grief (ICG), Adult Separation Anxiety Questionnaire (ASA-27), Work and Social Adjustment Scale (WSAS), and Mood Spectrum-Self Report (MOODS-SR) lifetime version. CG was strongly associated with female gender. MDD comorbidity was more common among patients with CG while bipolar disorder was highest among those with PTSD+CG. Patients with CG+PTSD reported significantly higher ASA-27 scores compared to patients with either CG or PTSD alone. Patients with CG+PTSD or PTSD alone reported significantly higher scores on the manic component of the MOODS-SR. No significant differences were reported in the WSAS scores. Our results support differences between CG and PTSD that are important for the consideration of including CG as a new disorder in the DSM-V.
