The Dipex Charity

We’re an independent charity based in Oxfordshire, UK. We collaborate with academic partners globally to generate and disseminate robust qualitative research findings for the benefit of the public. is our most recent offering, established as a social care companion site to our platform (formerly healthtalkonline), that has been going strong for more than 20 years. We also support the websites of our counterparts in the USA and Netherlands. Collectively, our websites support millions of individuals every year.

Beyond publishing qualitative research for the public benefit, we can help with digital data collection through the provision of websites, apps, and online focus groups.

Publish your social care research on

Publishing on gives social care researchers a unique opportunity to directly impact the public and enhance the visibility of your work. If you would like to discuss working with us to create a social care resource from your qualitative research, please contact us.
