Hi,
I Have a question, by using QLQ C30 questionnaire it is evaluated that score ranges from 0 to 100. A high scale score represents a higher response level.
I want to ask is there any reference or method available to cut off the domains value.
for example
I want to make 3 levels of quality of life in cancer patients based on QLQC30 mean scores.
1. Poor Qol
2. Moderate QoL
3. Excellent QoL
so how can I assign such values like if a score of 52.34 is there in which category it would fall?
thanks for the time.
