One-in-four gardaí may be suffering from work-related stress or trauma, according to a survey carried out for the Garda Representative Association.
The survey carried out by the psychotherapist Dr Finian Fallon describes 27% of those who responded as potentially "walking wounded".
Just over 2,200 gardaí responded to the email survey, a response rate of 38%, with two thirds of respondents male and one third female.
The survey also shows that gardaí feel frustrated by the amount of paperwork they have to do, they do not feel they have the right equipment and training to do the job properly, and that senior managers do not appreciate the challenges they face.
The GRA has said the majority of gardaí are not trained to properly police the State, particularly in areas of roads policing and sexual offences.
The organisation, which began its annual conference in Wexford yesterday, points out that detectives who carry guns are not trained in tactics, and frontline gardaí are not trained to respond to a terrorist incident.
It also said that most of the rank and file gardaí do not have the full driver training qualifications to allow them to turn on the siren and blue lights and pursue suspects.
The GRA said 52 new laws have been brought in over the past eight years, but there has been no classroom-based training for gardaí enforcing that legislation.
The GRA also says that the lack of welfare facilities for traumatised gardaí is a major concern.
A hard Brexit is also an issue with delegates pointing out that in such an event to police the 500km border with over 200 border crossings, they would need at least an extra 1,000 gardaí.
