Exploring Outcomes Related to Anxiety and Depression in Completers of a Randomized Controlled Trial of Complicated Grief Treatment.

The present study examines a more fine-grained analysis of anxiety-related and depression-related outcomes amongst a sample of treatment completers who were assigned to complicated grief treatment (CGT) ( n = 35) or interpersonal psychotherapy (IPT) ( n = 34) in a previously reported randomized controlled trial. We examined effects of antidepressant use and measures of anxiety and depression, focusing especially on guilt related to the death or deceased and grief-related avoidance in order to further understand the differential effectiveness of CGT and IPT amongst participants who received the full course of treatment. Analyses showed that CGT produced greater reductions in anxiety and depressive symptoms including negative thoughts about the future and grief-related avoidance. CGT's advantage over IPT in lowering depression was most pronounced amongst those not taking antidepressants. Our results further elucidate CGT effects and support the idea that CG and major depressive disorder are distinct conditions. Copyright © 2014 John Wiley & Sons, Ltd. Key Practitioner Message Targeted treatment for complicated grief (CG) produces benefits in associated mood and anxiety symptoms and CG symptoms., Amongst patients with CG, interpersonal psychotherapy seems relatively ineffective in ameliorating depressive symptoms., Grief-related depressive symptoms may not respond to standard treatments unless CG symptoms are also addressed., Reducing grief-related symptoms, such as anxieties about the future, guilt related to the death or deceased and avoidance of reminders of the loss may be important aspects in reducing CG.
