Purpose: To establish the reliability and construct validity of a new instrument to measure the presence and intensity of respiratory distress for patients unable to self-report. Conceptual framework: Respiratory distress is the observed corollary to the reported experience of dyspnea. Patients experiencing an asphyxial threat display similar behaviors arising from subcortical brain areas. A seven-item observation scale has putative clinical and research utility. Subjects: 70 subjects were recruited from a pulmonary rehabilitation clinic for convergent validity testing. A comparison sample of 70 patients with post-operative pain after orthopedic surgery was used to test discriminant validity and data from 70 healthy subjects allowed divergent validity testing. Method: Pulmonary rehabilitation subjects were assessed with the RDOS after controlled exercise and subsequently asked to mark a 100-point dyspnea visual analog scale (DVAS) at the point representing current dyspnea. Patients with pain were evaluated with the RDOS during the first 24 hours post-operatively immediately before analgesia administration and subsequently asked to mark the DVAS and to give a numeric report about current pain intensity. Healthy subjects were assessed with the RDOS at rest and asked to mark the DVAS. Results: Internal consistency of this seven variable scale is sufficient (alpha = .77). The mean oxygen saturation of the pulmonary disease subjects was 90.26% +/- 2.8. A positive correlation between the RDOS and DVAS (p=.001) and no significant difference in mean scores was found in dyspneic subjects. Pain scores did not correlate with RDOS or DVAS and there was a significant difference in mean pain scores and RDOS and DVAS (p = .000). Significant mean differences were found when RDOS scores from dyspneic subjects were compared to RDOS from healthy subjects (p=.000). Conclusions: The instrument is reliable and has convergent, discriminant, and divergent validity. There are clinical and research applications for this scale.
