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.

A cross-sectional convenience sample of 112 caregivers completed questionnaires to measure burden, personality traits, dysfunctional attitudes, and depression. The final model included direct paths from caregiver burden to autonomy and sociotropy, and indirect paths from burden to depression through sociotropy and autonomy. The final model fit adequately ([chi]2 [224, N = 112] = 308.60, p < .00; CFI = .951; RMSEA = .058). Levels of burden influenced caregiver depression scores. One pathway to depression was though the personality traits of sociotropy and autonomy; both had a larger influence on depression scores than burden alone. © 2009 Wiley Periodicals, Inc.
