The primary purpose of this secondary analysis was to determine whether 103 participants with chronic obstructive pulmonary disease rated the affective dimension of dyspnea (dyspnea-related anxiety and dyspnea-related distress) separately from the sensory dimension (intensity) during baseline exercise testing conducted as part of a randomized clinical trial. A secondary purpose was to determine if dyspnea-related anxiety and distress were rated distinctly different from other measurements of anxiety. At the end of a 6-minute walk and an incremental treadmill test, participant ratings of the magnitude of dyspnea-related anxiety and distress on the Modified Borg Scale were significantly different from their ratings of the intensity of dyspnea. Dyspnea-related anxiety and distress also appeared to be concepts independent from measures of state anxiety, negative affect, and anxiety before a treadmill test.
本次二次分析的主要目的是确定 103 名慢性阻塞性肺疾病患者在作为随机临床试验一部分进行的基线运动测试期间,是否将呼吸困难的情感维度(呼吸困难相关焦虑和呼吸困难相关困扰)与感觉维度(强度)分开进行评估。次要目的是确定呼吸困难相关焦虑和困扰是否与其他焦虑测量方法明显不同。在 6 分钟步行和递增跑步机测试结束时,参与者对改良 Borg 量表上呼吸困难相关焦虑和困扰严重程度的评分明显不同于他们对呼吸困难强度的评分。呼吸困难相关焦虑和困扰似乎也与状态焦虑、负性情绪和跑步机测试前的焦虑的测量方法独立。
