Effects of psychotherapy in moderately severe COPD: a pilot study

Area of Science:

• Pulmonology
• Psychiatry
• Rehabilitation

Background:

• Anxiety is prevalent in patients with chronic obstructive pulmonary disease (COPD), often termed "pink puffers."
• Anxiety severity correlates with perceived dyspnea in COPD patients.
• Cognitive and behavioral psychotherapy may offer benefits for COPD patients.

Purpose of the Study:

• To investigate the impact of group psychotherapy on anxiety, exercise tolerance, dyspnea, and quality of life in COPD patients.
• To assess the sustained effects of psychotherapy on these parameters.

Main Methods:

• A pilot study involving ten patients with moderately severe, stable COPD who received six weekly 90-minute sessions of cognitive and behavioral psychotherapy.
• Measurements included the Hospital Anxiety and Depression Scale (HADS), Medical Research Council Questionnaire (MRCQ), St George's Respiratory Questionnaires (SGRQ), lung function tests (FEV1, FVC, SVC), blood gas tensions, and 6-minute walking distance (6MWD).
• A control group of eight COPD patients underwent lung function and 6MWD assessments without psychotherapy.

Main Results:

• The psychotherapy group showed a significant improvement in 6-minute walking distance (6MWD) post-therapy, increasing by 24% (from 351m to 423m).
• This improvement in 6MWD was sustained at three months post-treatment, remaining 16% above baseline.
• No significant changes were observed in anxiety scores (HADS), other psychological measures, or physiological parameters in either group.

Conclusions:

• Six sessions of cognitive and behavioral psychotherapy led to a sustained enhancement in exercise tolerance in anxious COPD patients.
• The improvement in 6MWD occurred without a corresponding change in anxiety scores.
• Further research with more intensive psychotherapy is warranted to explore potential improvements in symptom and quality of life scores.
