This article is an account of our practical research and cooperation experience from a
participatory research project on homelessness and psychosocial disability carried out in a
Hungarian university context, by a student and two experts by experience in a researcher role.
We argue for the involvement of disadvantaged people using social services in research related
to disadvantaged people and social services, highlighting the advantages and challenges of this
kind of research based on our experience. Finally, we formulate practical recommendations that
migh be useful for beginners – like we used to be – in participatory research in this field.
