About this study
Official title: Cognitive Behavioral Therapy in Primary Care: Treating the Medically Ill
The current study seeks to test the effectiveness of a talk-therapy intervention designed to better meet the needs of chronically ill Veterans. This project looks to recruit 450 Veterans with either chronic obstructive pulmonary disease (COPD) or heart failure (HF) who also have symptoms of worry, stress, anxiety, or sadness. Participants will be randomly put into either the talk-therapy intervention or enhanced usual care.
The talk therapy intervention will be provided by VA clinicians in the primary care setting and will consist of 6 core meetings (30-45 minutes in duration) and 2 follow-up telephone meetings. Enhanced usual care participants will receive feedback regarding the assessment findings and educational materials on COPD and/or HF, depression and anxiety.
Read the detailed description
Diseases of the heart and circulatory system, namely, Chronic Obstructive Pulmonary Disease (COPD) and Heart Failure (HF), are two of the most common and disabling chronic diseases. Both COPD and HF account for significant disability, mortality, and healthcare costs and are associated with lower health status and more functional and social limitations than other chronic illnesses, such as hypertension and diabetes. As our population ages and life span increases, the numbers of patients with these conditions and the subsequent healthcare costs will increase dramatically.
The symptoms associated with COPD and HF can significantly affect daily functioning. Physical symptoms are often linked to increased levels of psychological distress, namely, anxiety and depression, which significantly affect quality of life and functioning above and beyond the impact of the medical disease. As depression and anxiety are modifiable clinical factors, there is a potential to significantly alter patient outcomes, as well as use of healthcare services. However, focused interventions are needed, given the high risk for poor mental health treatment and underuse of mental health services in persons with COPD and HF. Unfortunately, few intervention studies have been conducted in medically ill patients with these conditions. The current project will examine whether existing VA clinicians in the primary care setting, with training and support, can effectively administer a structured Cognitive Behavioral Therapy (CBT) intervention for depressed and anxious Veterans with COPD and HF.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ACCESSBehavioural
Participants received 6 treatment sessions (2 core and 4 electives). The two core modules are increasing awareness and controlling physical and emotional symptoms. After completion of the core modules the participant was able to choose elective modules from Managing Physical Health, The Power of Thoughts, Increasing Pleasant Activities, and Relaxation. Participants were required to complete the first session in person and subsequent sessions participants had the option to complete in-person or over the phone. Participants also had the option to receive 2 brief follow-up booster calls to aid in reinforcing the changes made.
| Study group | Role | What they receive |
|---|---|---|
| ACCESS | Experimental | Medically ill patients received six-sessions of cognitive behavioral therapy tailored to their unique needs. Patients received 2 core modules and 3 elective modules. Elective modules focused on physical health, cognitive restructuring, behavioral activation, and relaxation. The six session was a wrap up that everyone received. Patients also had the option to receive 2 follow-up booster sessions to aid in maintenance of skills learned. Receives: Behavioral: ACCESS |
| Enhanced Usual Care | No intervention | Patients in this arm received feedback about their physical and emotional health functioning and were still able to receive usual primary care services. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Patient Health Questionnaire -9 (PHQ-9)
The PHQ-9 measures an individual's level of depression. The measure is summed and ranges from 0 - 27 (individual item score range 0 - 3 per 9 items); where higher scores = worse symptoms.
Measured: 4 month (post treatment), 8 month follow/up, and 12 month follow/up
Beck Anxiety Inventory (BAI)
The BAI measures an individual's level of anxiety. The measure is summed and ranges from 0 - 63 (individual item score range 0 -3 per 21 items); were higher scores = worse symptoms.
Measured: 4 month (post treatment), 8 month follow/up, and 12 month follow/up
Chronic Respiratory Questionnaire_Fatigue
The Chronic Respiratory Questionnaire (CRQ) measures the quality of life of patients with a chronic respiratory disease. This subscale measures the amount of fatigue patients experience with the condition. The CRQ is a mean score and ranges from 1 - 7, where a higher score = better health.
Measured: 4 month (post treatment), 8 month follow/up, 12 month follow/up
Chronic Respiratory Questionnaire_Mastery
The Chronic Respiratory Questionnaire (CRQ) measures the quality of life of patients with a chronic respiratory disease. The subscale Mastery looks at the patient's perceived control over the condition. The CRQ is a mean score and ranges from 1 - 7, where a higher score = better health
Measured: 4 month (post treatment), 8 month follow/up, 12 month follow/up
Chronic Respiratory Questionnaire_Dyspnea
The Chronic Respiratory Questionnaire (CRQ) measures the quality of life of patients with a chronic respiratory disease. The subscale Dyspnea looks at how much shortness of breath a patient experiences. The CRQ is a mean score and ranges from 1 - 7, where a higher score = better health.
Measured: 4 month (post treatment), 8 month follow/up, 12 month follow/up
Kansas City Cardiomyopathy Questionnaire (KCCQ)
The KCCQ measures the health status of patients with congestive heart failure. The overall score is a mean score scaled from 0 - 100; where 0 represents most severe/limited functioning.
Measured: 4 month (post treatment), 8 month follow/up, and 12 month follow/up

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The current study seeks to test the effectiveness of a talk-therapy intervention designed to better meet the needs of chronically ill Veterans. This project looks to recruit 450 Veterans with either chronic obstructive pulmonary disease (COPD) or heart failure (HF) who also have symptoms of worry, stress, anxiety, or sadness. Participants will be randomly put into either the talk-therapy intervention or enhanced usual care.
The talk therapy intervention will be provided by VA clinicians in the primary care setting and will consist of 6 core meetings (30-45 minutes in duration) and 2 follow-up telephone meetings. Enhanced usual care participants will receive feedback regarding the assessment findings and educational materials on COPD and/or HF, depression and anxiety.
