Brief Summary:

The purpose of this study is to learn more about the causes of Complicated Grief (CG) in those who experience the loss of a loved one. This study aims at learning more about the sleep patterns and emotions in participants with CG as compared to those who have lost a loved one but do not have CG.

This study will consist of two aims:

Aim 1: Approximately 10 complicated grief (CG) patients and 10 controls (without a current psychiatric diagnosis) will complete a 3-day home polysomnography (PSG) sleep assessment in addition to several self-report sleep and psychiatric measures.

Aim 2: Approximately 10 CG patients (subsample from Aim 1) will complete 16 weekly sessions of complicated grief therapy (CGT) in addition to completion of repeated PSG assessments and self-report sleep and psychiatric measures.
