A Home-based Intervention to Promote Mindful Breathing Awareness Through Pursed-lip Breathing Training for COPD Patients

Not Applicable

Completed

• Conditions: Chronic Obstructive Pulmonary Disease
• Interventions: Behavioral: Mindful Breathing; Behavioral: Home-Based Pulmonary Rehabilitation

• Registration Number: NCT05349123
• Lead Sponsor: Minnesota HealthSolutions

Brief Summary

The Mindful Breathing Laboratory under the direction of Dr. Benzo will complete a randomized controlled trial to evaluate the mindful breathing module. This rigorous study will evaluate home-based PR system compared to the home-based PR system plus mindful breathing module for its effects on breathlessness and emotions. The investigators hypothesize that the intervention will decrease breathlessness while increasing emotional perception, emotional intelligence, and mindfulness.

Detailed Description

A total of 50 adults diagnosed with COPD will be enrolled in this study. Half of the subjects will be randomized to receive home-based pulmonary rehabilitation with the mindful breathing module (intervention group) and half will receive home-based pulmonary rehabilitation (control group). Each subject will be consented and trained and then participate in either the intervention or control group. Both groups entail one week of baseline and twelve weeks of home-based pulmonary rehabilitation (health coaching plus activity monitoring). The intervention group will also receive the mindful breathing module during the twelve weeks of home-based pulmonary rehabilitation. The Chronic Respiratory Disease Questionnaire (CRQ) will be administered at baseline, week 12 (after the intervention) and week 24 as the investigators will follow the patients for 3 months after the intervention to document the sustainability of the effects (behavior change).

Arm && Interventions

Group	Intervention	Description
Intervention	Mindful Breathing	Home-based pulmonary rehabilitation that includes health coaching with mindful breathing module
Control	Home-Based Pulmonary Rehabilitation	Home-based pulmonary rehabilitation that includes health coaching
Intervention	Home-Based Pulmonary Rehabilitation	Home-based pulmonary rehabilitation that includes health coaching with mindful breathing module

Primary Outcome Measures

Name	Time	Method
Breathlessness	12 weeks	Breathlessness as measured by the Chronic Respiratory Disease Questionnaire. The Chronic Respiratory Disease Questionnaire is a 20-question inventory assessing four areas, including dyspnea (breathlessness). Patients rate their experience numerically on a 7-point modified Likert scale of 1 to7 with higher ratings indicating less symptom impairment. Scores are obtained by adding the scores for the items that make up each category and dividing by the number of items. A minimally important difference is a change in score of 0.5 or more.
Emotion	12 weeks	Emotion as measured by the Chronic Respiratory Disease Questionnaire. The Chronic Respiratory Disease Questionnaire is a 20-question inventory assessing four areas, including emotion. Patients rate their experience numerically on a 7-point modified Likert scale of 1 to7 with higher ratings indicating less symptom impairment. Scores are obtained by adding the scores for the items that make up each category and dividing by the number of items. A minimally important difference is a change in score of 0.5 or more.
