Research question:
Does Non-pharmaceutical intervention (Tai Chi, Qigong, light exercise... ) effect on symptom clusters such as cluster 1 (Fatigue, dyspnea, and cough) or cluster 2 (Fatigue, dyspnea, cough, and pain), or cluster 3 (Fatigue, dyspnea, cough, pain, and anxiety)...on cancer population?
Statistics question:
Which statistical test that I could use to analyze the effectiveness of an intervention to each symptom, cluster symptom, and the correlation between and within each symptom in a cluster?
Thanks!
Disclaimer: I have no experience with the analysis you intend to perform, but I'm interested to learn how you will solve it. Perhaps you can find the answer via this link to StackOverflow (https://stackoverflow.com/questions/17866915/how-to-compare-clusters). Alternatively the EFA and CFA models may help to answer your question. Will you let me know how you've solved it?
Hello,
I think if provide more information on your research question such as what is nature of your dependent variable (i.e. is it categorical or continuous), how your intervention is measured, etc, it's easier and clearer to find appropriate statistical test for your research questions.
Good luck!

You can use one-way ANOVA, where non-pharmaceutical interventions are different levels (factors) of independent variable and the cluster 1 is a dependent variable. Then, repeat this analysis for the other two clusters which are dependent variables.
