Improvement in exercise tolerance, quality of life (QOL), and self-efficacy (SE) have been demonstrated after comprehensive pulmonary rehabilitation. It is unclear, however, whether improvement in these three areas is related. To evaluate this, the present study compared changes in 6-minute walking distance (6 MD), QOL, and 6- minute walking distance self-efficacy in 20 patients diagnosed with chronic obstructive pulmonary disease (COPD) completing a 12-week outpatient pulmonary rehabilitation program (OPR). QOL was measured with the Chronic Respiratory Disease Questionnaire (CRQ), a self-report tool that assesses dyspnea, fatigue, emotional function, and disease mastery. After completing an OPR program, significant improvements (p < .0001) were found in 6 MD, 6 MD self-efficacy, total QOL, and all four dimensions of the CRQ. Despite these gains, there was no significant relationship between the physiological and psychological variables of interest. This lack of association suggested that changes occurring over the course of the OPR were most likely a result of factors beyond the exercise intervention. Key words: self-efficacy, outpatient pulmonary rehabilitation, quality of life, exercise tolerance, chronic obstructive pulmonary disease
