Problem-Solving Therapy for People With Major Depression and Chronic Obstructive Pulmonary Disease

This study will evaluate the effectiveness of problem-solving therapy combined with treatment adherence procedures in treating older people with major depression and chronic obstructive pulmonary disease.

Depression is a serious illness that affects a person's mood, thoughts, and physical well-being. Common symptoms of depression include persistent feelings of anxiety, guilt, or hopelessness; irregular sleep and appetite patterns; lethargy; disinterest in previously enjoyed activities; excessive irritability and restlessness; suicidal thoughts; and inability to concentrate. Depression often occurs in the presence of one or more other disorders. For example, depression is reported to be at a higher rate in people with chronic obstructive pulmonary disease (COPD) than in the general population. COPD is a disease in which the lungs are damaged, making it difficult to breathe. Symptoms most commonly include chronic coughing and shortness of breath. A primary cause of COPD is cigarette smoking. Following a prescribed treatment plan is important for managing COPD. Unfortunately, people with COPD often do not adhere to their treatment plans. Being depressed makes adherence even more difficult. This study will evaluate the effectiveness of problem-solving therapy integrated with adherence-enhanced procedures (PSA) in treating older people with major depression and COPD.

Participants in this open label study will be randomly assigned to one of two groups: PSA or PID-C. In PSA, a therapist will teach participants problem-solving strategies focusing on treatment adherence, depressive symptoms, and disability. Participants will learn behaviors and solutions to help cope with these problems. In PID-C, a therapist will teach participants to identify obstacles to treatment adherence and to discover ways to overcome them. The treatment sessions for both groups will be initiated at the inpatient Pulmonary Unit of Burke Rehabilitation Hospital and will continue in the participants' homes. All participants will receive two treatment sessions during hospitalization, eight weekly sessions following discharge, and four monthly sessions after that. While hospitalized at Burke, participants will also undergo an assessment interview for 1.5 hours and another interview for 20 minutes 2 weeks following the initial assessment. Interviews lasting 1.5 hours will also occur in the homes of the participants at Weeks 10, 14, and 26 after discharge from Burke. All assessments will focus on depression severity, level of general functioning, and COPD treatment adherence.
