Trial Outcomes & Findings for A Home-based Intervention to Promote Mindful Breathing Awareness Through Pursed-lip Breathing Training for COPD Patients (NCT NCT05349123)

NCT ID: NCT05349123

Last Updated: 2025-06-06

Results Overview

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.

PRIMARY outcome

Timeframe: baseline, 3 months, 6 months

Population: For the Intervention group with mindful breathing module arm, nineteen subjects did not complete the three months or six months questionnaire. Data was not collected or analyzed. For the Control group, twenty-six subjects did not complete the three months questionnaire and twenty-eight subjects did not complete the six months questionnaire. Data was not collected or analyzed.
