| Abstract: | 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. © 2009 Wiley Periodicals, Inc.
