Preventing duplication of sources when have multiple interviews from same participant?

Recommended Posts


Participants in our project complete an interview at the end of the intervention, and then do three follow up interviews at various time intervals.

I am wondering if there is a way I can code all of the interviews belonging to one participant, without increasing the number of sources at each node? Or, if there is a way to add an additional field that can show the number of participants connected to each node (as well as the number of sources)?

I'm quite new to NVivo 11 and haven't used cases or case classifications before. From what I've read I think this might be how I need to do it, although I can't see a way of linking the number of cases to each node, if that's possible.

The only other way I can think of doing this, would be to wait until I had all of the interviews back form one participant, and then import them all as one source to analyse. But that's not ideal as it will  delay or analysis.

Hi Nicky, 

You could create a case for each of your participants and code all of their interviews to their case node. Later on, you could use a query to see how many participants (cases) are coded to each theme node. There is not a simple way to do this, but the following should give you the information you are after. 

First, create a set that contains all of your participant cases. You can then run a matrix coding query that has your nodes as the rows and this set as the columns. Once you have run your query you can change the matrix cell content to display cases coded. 

You can find information about cases at the following link:
