The Rape Crisis Network (RCNI) is adding its voice to calls for Direct Provision reform.
The government has already set up a working group to look at improvements that need to be made, following a number of protests at facilities around the country in recent months.
RCNI researchers have been studying the accounts of 61 people living in centres who made contact with their services in 2012 - the vast majority of whom had been victims of rape in the past.
Judge Catherine McGuinness is to launch the research today.
RCNI chairperson Anne Scully says they are concerned about people who may have felt they could not seek help.
And she has outlined the concerns that some residents have brought to their counsellors.
