背景：慢性阻塞性肺病的病人普遍都會有呼吸困難的情況，增進其呼吸困難自我管理是相當重要的，因此欲瞭解內外控傾向的健康態度和呼吸困難自我管理的相關性。目的：探討健康內外控與呼吸困難自我管理策略之相關性。方法：採橫斷式描述相關性研究，由研究者以「個人基本資料表」和「活動後呼吸困難量表」評估研究對象的特性，以「多層面健康控制信念量表」及「呼吸困難自我管理策略量表」收集資料後，再以SPSS 17.0 for Windows統計軟體進行分析。研究對象為某醫學中心及地區醫院胸腔內科門診病患，共得200份有效問卷。結果：(一)個案健康內外控平均得分以「權力在他人」最多28.05 ± 6.07，其次為內控25.02 ± 9.01，「機運」為最低20.83 ± 9.78。(二)內控與呼吸困難自我管理策略使用頻率及效果呈現正相關(p = .001)；機運及權利在他人與呼吸困難自我管理策略使用頻率及效果呈現負相關(p = .001)。以多元線性回歸分析，結果發現內控與機運為呼吸困難自我管理策略使用頻率及效果的重要預測因子(p < .05)。結論：健康內外控的特性與呼吸困難自我管理策略是有相關的，內控較外控傾向之個案呼吸困難自我管理策略使用頻率越高、效果越好。未來可將此結論運用在臨床實務上，以增加病人自我管理的效益。

Background: Dyspnea is a debilitative condition that often affects chronic obstructive pulmonary disease (COPD)patients. Enhancing the efficacy of patient self‐management strategies for dyspnea is thus a very important issue.Purpose: This study explores the correlation between the health locus of control and dyspnea self‐management strategies in patients with chronic obstructive pulmonary disease.Methods: Using a cross‐section descriptive correlational approach, researchers enrolled a total of 200 COPD patients treated at a local teaching hospital in South Taiwan as participants. We used demographics and a post‐physical‐activity dyspnea survey forms to assess patient characteristics and the Multi‐Dimensional Health Locus of Control and Dyspnea Self‐Management Strategies scales to collect study data. Statistical analysis was performed using SPSS 17.0.Results: “Powerful others” earned the highest locus of control orientation score (28.05 ± 6.07) followed by internal locus of control (25.02 ± 9.01). “Chance” ear ed the lowest score (20.83 ± 9.78). We also found a positive correlation between internal locus of control and dyspnea self‐management strategies (p = .001) and negative correlations between the “chance” and “powerful others” locus of control and dyspnea selfmanagement strategies (p = .001). Multiple linear regression analysis results showed the significant impact of internal locus control and “chance” on the frequency and effectiveness of using dyspnea self‐management strategies. (p < .05)Conclusion: There is a correlation between health locus of control and dyspnea self‐management strategies.Those with better internal loci of control were found to have better relative dyspnea self‐management strategies. This conclusion may be applied in clinical practice to improve self‐management effectiveness.
