Effects of Video Modeling on Self-Efficacy and Exercise Performance of Copd Patients

Abstract

We studied the effect of an exercise-based pulmonary rehabilitation program for persons with chronic obstructive pulmonary disease (COPD). Effects of a complemented video-modeling strategy were studied and compared to the control group which adopted behavioral training strategies in the exercise program only. Eleven patients with COPD received a 1-month (3 times per week) behavioral exercise program with video modeling. Another 11 patients participated in a control group which performed the same exercise without video modeling. The patients' exercise intensity was monitored by prestudy stress tests to ensure that the participants were all having a comparable level of submaximal exercise. They participated in an exercise program which included gradual upgrading of walking on the treadmill, or cycling, and a 5-point rating scale assessed their performance level. Their self-efficacy was assessed by using an exercise self-efficacy scale complemented with open-ended questions to elicit their viewpoints on factors affecting their exercise performance, including the video modeling strategy. From the results, both groups showed statistic-ally significant improvement in exercise performance and self-efficacy. Participants in the video-modeling group showed greater -though

Modeling: Is what you see, what you get?

“…in clinical populations, coping models have also shown promise for enhancing patients' rehabilitation experiences. often individuals diagnosed with chronic heart failure or other chronic disease (e.g., chronic obstructive pulmonary disease) are prescribed exercise as part of their disease management and rehabilitation but become anxious about increased heart rate and breathing rate associated with exercise, as they are symptoms they also associate with their medical conditions (see Maddison, Prapavessis, Armstrong, & hill 2008;Ng, yuen, Tam, yew, & lam, 1999).…”
