If you use the ORRCA database, please reference it in any reports or publications by including the following statement: Articles were identified through a search of the ORRCA recruitment research database (www.orrca.org.uk).
If you are currently working on a project that you think is relevant then you can also submit this to ORRCA using the “tell us about a new project/study form”.
