Development and Evaluation of Motivational Interviewing Pulmonary Rehabilitation Program Based on Self-Determination Theory for Patients with Chronic Obstructive Pulmonary Disease

Abstract

This study aimed to develop a motivational interviewing pulmonary rehabilitation program based on self-determination theory to maintain pulmonary rehabilitation-related health behaviors in patients with chronic obstructive pulmonary disease. The program was developed by reviewing the literature on pulmonary rehabilitation guidelines, drawing on the self-determinism theory to establish its contents, recruiting experts to test its validity, and conducting a preliminary survey. A quasi-experimental design was used to confirm the effect of the program. The participants were outpatients diagnosed with chronic obstructive pulmonary disease at three general hospitals in Busan. There were 33 subjects: 15 in the experimental group and 18 in the control group. The experimental group performed a motivational interviewing pulmonary rehabilitation program which comprised 11 sessions delivered over 10 weeks. The outcomes were measured using basic psychological needs, dyspnea, 6-minute walking distance, and functional status. Intervention effects were analyzed using repeated-measures ANOVA. The analysis revealed significant differences between the experimental and control groups in competence among the subdomains of basic psychological needs, dyspnea during exercise, and functional status. The developed program affects physical conditions and can be applied as an effective clinical nursing intervention to continuously improve the pulmonary rehabilitation behavior of patients with chronic obstructive pulmonary disease.
