Insomnia | A Behavioral Therapy for Insomnia Co-existing With COPD
Insomnia research study
What is the primary objective of this study?
Difficulty falling asleep, staying asleep or poor quality sleep (insomnia) is common in people with chronic obstructive pulmonary disease. Insomnia is related to greater mortality, with four times the risk of mortality for sleep times < 300 minutes. Insomnia is also related to greater morbidity, with 75% greater health care costs than people without insomnia. However, insomnia medications are used with caution in COPD due to potential adverse effects. Common features of COPD such as dyspnea, chronic inflammation, anxiety and depression also affect insomnia and can interfere with therapy outcomes. While cognitive behavioral therapy for insomnia (CBT-I), a therapy that provides guidance on changing unhelpful sleep-related beliefs and behavior, is effective for people with primary insomnia and people with other chronic illnesses, the efficacy and mechanisms of action of such a therapy are yet unclear in people with both insomnia and COPD. The objective in this application is to rigorously test efficacy of two components of insomnia therapy - CBT-I and COPD education (COPD-ED) - in people with coexisting insomnia and COPD, and to identify mechanisms responsible for therapy outcomes. The central hypothesis is that both CBT-I and COPD-ED will have positive, lasting effects on objectively and subjectively measured insomnia and fatigue. The rationale for the proposed study is that once the efficacy and mechanisms of CBT-I and COPD-ED are known, new and innovative approaches for insomnia coexisting with COPD can be developed, thereby leading to longer, higher quality and more productive lives for people with COPD, and reduced societal cost due to the effects of insomnia. The investigators plan to test our central hypothesis by completing a randomized controlled comparison of CBT-I, COPD-ED and non-COPD, non-sleep health education attention control (AC) using a highly efficient 4-group design. Arm 1 comprises 6 weekly sessions of CBT-I+AC; Arm 2=6 sessions of COPD-ED+AC; Arm 3=CBT-I+COPD-ED; and Arm 4=AC. This design will allow completion of the following Specific Aims: 1. Determine the efficacy of individual treatment components, CBT-I and COPD-ED, on insomnia and fatigue. 2. Define mechanistic contributors to the outcomes after CBT-I and COPD-ED. The research proposed in this application is innovative because it represents a new and substantive departure from the usual insomnia therapy, namely by testing traditional CBT-I with education to enhance outcomes.

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?
Chronic Obstructive Pulmonary Disease
Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
