本研究採橫斷性調查研究法，目的在探討慢性阻塞性肺疾病患者在運動改變階段及運動改變過程之關聯性。資料收集方式由研究者採一問一答方式來完成問卷。以運動改變階段、運動改變過程量表及人口學基本資料為研究工具，以南部某醫學中心胸腔內科門診98位慢性阻塞性肺疾病患者為對象。研究對象平均年齡為68.1歲，在運動階段的分類上有25.5%的人為動機前期、2.0%為動機期、21.4%為準備期、4.1%為行動期及46.9%為維持期，有規律運動者以散步為主要運動方式。結果發現研究對象運動改變過程量表中以「情境替代」得分最高，是慢性阻塞性肺疾病患者改變原來不運動生活型態最常採用的方法。進一步探討五個運動改變階段與十種改變過程結果發現，運動前期得分明顯低於其他運動改變階段，較少採取策略來改變運動行為。本研究結果可作為未來臨床實務工作者發展不同運動階段介入運動計畫之參考。

This study uses a horizontal investigative method; the purpose of this study was the application of the transtheoretical model to the exercise behavior of patients with chronic obstructive pulmonary disease (COPD). Constructed questionnaires were utilized to interview the subjects; the questionnaires contained personal demographics, stages of exercise, and processes of change. Purposive sampling was conducted at a medical center in Southern Taiwan. Ninety-eight valid questionnaires were collected. Subjects ranged 39-83 years of age (M = 68.1, SD = 10.4). Exercise activities in the sample were divided between pre-contemplation (25.5%), contemplation (2%), preparation (21.4%), action (4.1%), and maintenance (46.9%). Walking proved the most common exercise method. For processes of change, the ranked top was counter-conditioning indicating that COPD patients most frequently sought alternative activities to replace status of no exercise. In terms of interrelations between ten processes and five stages, the precontemplation stage scored manifestly lower on processes of change than any other stage. The findings of this study provide guidance to clinical practitioners in developing stage-matched interventions, promotional strategies with a variety of program planning, and suggestions for research agencies in the future.
