Microsoft forms help

Hi,

I am wanting to use Microsoft forms for my MSc dissertation but have a few questions about linking forms collecting data over an extended time period.

I need my participants to fill in multiple questionnaires before an intervention, after and then a month after. Their data will need to remain anonymous but I will need to compare their changes over the time period.

I will need to do this for three different interventions groups with approximately 30 participants in each?

Does anyone know if this is possible please?
