Dear Scientists,
I have conducted a Interventional study with pre-post design where outcomes are measure before and after the intervention. In my study, I also have control group (so study design is "Mult-arm pre-post study). I selected patients through block randomization. I have an argument in scientific community that randomization can only be used for Clinical Trials. My study is not clinical trial, its just prospective intervention study. Is randomization in this study appropriate?
Is randomization appropriate", why not?
It is not clear why you think that you do not have a clinical trial. You have intervention, control, and randomization; this is an experimental (trial) design. What is you outcome?
Yes it's a randomized controlled trial and not a pre post quasi experimental trial as you have control, intervention and randomization.
Why not?
In my opinion, this is a clinical trial; as you have the intervention, control group, and experimental design. I totally agree with Prof. Muhammad M Hammami and Dr. Sumanta Chakraborty
I think it should be in 2 different groups to avo the effect of biases and confounders

I just want to clear that can we use randomization procedures for studies other than clinical trials.
If you want to generate unbiased data and your study-design allows randomization, i don't see why you should not do it. Doesn't matter if it's a clinical trial or not.
Randomization is appropriate for your study.. As it is a international study with control group it will be true experimental research design which is the strength of your study.
You are already conducting a randomized controlled trial (maybe it lacks blinding and allocation concealment) but it is a RCT.
Measuring pre and post the intervention allows you to compare the magnitude of the change in the 2 groups.
Hi! You might want to check this free online randomization app. You can apply simple randomization, block randomization with random block sizes and also stratified randomization.
