Many people directly affected by the 9/11 terrorist attacks still suffer constant grief, says an American Red Cross survey released Friday.

Nearly two-thirds of the 1,500 emergency responders, survivors and victims' relatives who took part in the survey believe that grief still interferes to a moderate or large extent in their lives, The New York Times reported.

Just over 40 percent said they still need additional services to help them recover -- including mental health services, financial assistance, and medical services.

Uniformed responders and people closest to the recovery efforts have been most affected by mental distress, the survey found. This link between mental health problems and proximity to the attacks was noted in a recently published study on survivors, the Times reported.

That study, conducted by the New York Department of Health and Mental Hygiene and the U.S. Centers for Disease Control and Prevention, found that people engulfed by the dust cloud caused by the collapse of the World Trade Center towers were more likely to be struggling with stress and other mental health issues, compared to those who got out of the buildings earlier.
