Two Interventions for PatientsWith Major Depression and Severe Chronic Obstructive Pulmonary Disease: Impact on Quality of Life.

ABSTRACT: OBJECTIVE:Clinically significant depression occurs in approximately 40% of chronic obstructive pulmonary disease (COPD) patients, and both illnesses severely impair quality of life. This study tests the hypothesis that problem-solving integrated with a treatment adherence intervention, the Problem Solving-Adherence (PSA), is superior to a personalized treatment adherence intervention, the Personalized Intervention for Depressed Patients with COPD (PID-C), alone in improving quality of life in depressed COPD patients. METHODS:After screening 633 admissions for acute rehabilitation, we studied quality of life in 87 participants with major depression (by Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) and severe COPD randomly assigned to 14 sessions of PID-C or PSA over 26 weeks. Quality of life was assessed using the Word Health Organization Quality of Life-BREF at baseline and weeks 10, 14, and 26. RESULTS:The hypothesis was not supported. Exploratory latent class growth modeling identified two quality of life trajectories. In 80.5% of participants, quality of life remained unchanged and improved in the remaining 19.5% during the first 14 weeks. Patients with a stable quality trajectory had higher qualityof life at baseline and a stronger sense of personal agency. CONCLUSION:Maintaining quality of life is a favorable outcome in depressed patients with COPD whose course is one of deterioration. These findings highlight the usefulness of PID-C, an easy to learn, personalized adherence enhancement intervention that, after further testing, may be integrated into the rehabilitation and care of depressed COPD patients.
