In the present sample, the scale showed good internal consistency (patients' self-report: Cronbach's alpha=0.92, spouses' report: Cronbach's alpha=0.91). The scale further demonstrated high correlations with questionnaires assessing related constructs [St. George's Respiratory Questionnaire (SGRQ): Pearson's correlation coefficients r=0.59 to 0.83, p
