Hello Jennifer,

If you don't get any help, perhaps contact these authors on ResearchGate? Although of the authors of the CISS, only Cosway is a RG member but the authors of the other papers have used CISS:

Hi Mary

Wow - thank you so much!  That is brilliant.  Thanks for taking the time to respond - I am thrilled. Isn't Research Gate fantastic.  'Hope your own work is going well.  Jenny x

Hello Jennifer,

I've just realised (and amended my answer), it is Cosway who is a RG member, or perhaps contactable through NHS Education for Scotland, Edinburgh.

Very best wishes with this,

Mary 

Thanks Mary
