Negative symptoms associated with COPD (e.g. dyspnea) limits the individual’s functional abilities and independence, thus worsening anxious and depressive feelings and impacting the perception of their quality of life (Paz-Diaz et al., 2007). The Theory of Unpleasant Symptoms supports this research (Lenz et al., 1997). A crucial part to COPD management is Pulmonary Rehabilitation, PR, to improve functional abilities through exercise. PR is correlated with improvements in perceived quality of life (Paz-Diaz et al., 2007). An adjunct intervention to PR is Distractive Auditory Stimuli, which uses a positive stimulus (music) to turn attention away from a negative experience (e.g. dyspnea). This study is a secondary analysis of a previous study evaluating the effect of Distractive Auditory Stimuli on walking in persons with COPD. A sample of 24 participants with COPD was randomly divided into an intervention group (listened to music while exercising) and a control group (exercised without music). Health-related quality of life (HRQoL) data was obtained using the St. George Respiratory Questionnaire. HRQoL indicators are defined as the specific activities discussed in the questions related to symptomatology. Dichotomous symptom variables (n=18) were identified from specific SGRQ questions as part of the raw data of the primary study. A data set was formed using SPSS software including variables describing the change in symptoms from baseline to eight weeks as one of four ordinal change outcomes. Using SPSS, the data was analyzed using the Kendall’s Tau-b in crosstabs. A significant difference was noted for panic with dyspnea (p=.043) and dyspnea with talking (p=.013). Dyspnea while bending over trended towards significance (p=.08). However 15 symptoms had no significant differences. As reported in the primary study, outcomes related to health-related quality of life were determined to be underpowered. Insight into holistic results of treatment can help to optimize care given to this population.
