They are also more likely to be disatisfied with their work-life balance, and level of managerial support than other NHS workers.
The independent watchdog the Healthcare Commission based its findings on a survey of over 200,000 NHS employees.
It is calling for urgent action to address the problem of violence and intimidation of NHS staff.
The analysis showed:
Anna Walker, HC chief executive, said: "People who care for everyone's health needs should not have to endure violence or harassment as part of their daily working life.
"We urge NHS organisations to investigate and address these issues and examine the scope to improve work life balance and reduce work pressure for staff."
The NHS Security Management Service recently took over responsibility for all security management issues in the NHS.
It launched a new strategy to tackle violence against NHS staff in December 2003, including a pledge to take swift legal action against anyone who assaults NHS staff and conflict resolution training for all front-line workers.
Jim Gee, the chief executive, said recent figures compiled by his organisation showed that NHS staff were now reporting far more incidents of violence than in the past - a strong indication that people were no longer prepared to tolerate violence and aggression.
He said: "We take the problem of violence and aggression seriously and are determined to deliver an environment for those who use or work in the NHS which is properly secure so that the highest possible standard of clinical care can be made available."
