Effectiveness of an inpatient group therapy for comorbid complicated grief disorder.

We investigated whether inpatients suffering from comorbid complicated grief disorder benefited from an additional manualized nine-session group intervention. For this purpose, 50 patients participating in the additional complicated grief intervention were compared with 22 control patients who received treatment as usual. After grief intervention, we found large effect sizes with regard to improvement in complicated grief symptoms. Because we found no differences regarding overall mental distress and depressive symptoms (between the two groups), the grief intervention seems to be highly specific.
