Hypothesis
The study aimed to develop and validate a brief self-rating scale to assess the multidimensional nature of dyspnoea in cancer patients.
Conclusion
The Cancer Dyspnoea Scale is a brief, valid, and feasible tool for assessing dyspnoea in cancer patients.
Supporting Evidence
- The Cancer Dyspnoea Scale was developed using factor analysis.
- The scale showed good feasibility with an average completion time of 140 seconds.
- Construct validity was confirmed by repeating factor analysis.
- Convergent validity was established with a relation to the Visual Analogue Scale of dyspnoea and modified Borg's scale.
- The internal consistency of the scale was high with an average Cronbach's alpha of 0.86.
- The stability of the scale was confirmed with an average test-retest reliability of r = 0.66.
Takeaway
Researchers created a simple questionnaire to help cancer patients describe their breathing difficulties, and it works well.
