This study examined the prevalence, correlates, and perceived mental healthcare needs associated with subsyndromal PTSD in police involved in the World Trade Center (WTC) rescue and recovery effort.


A total of 8466 police completed an interview/survey as part of the WTC Medical monitoring and Treatment Program an average of four years after 9/11/2001.


The past month prevalence of full and subsyndromal WTC-related PTSD was 5.4% and 15.4%, respectively. Loss of someone or knowing someone injured on 9/11 (odds ratios [ORs]=1.56-1.86), pre-9/11 stressors (ORs=1.30-1.50), family support (ORs=0.83-0.94), and union membership (ORs=0.50-0.52) were associated with both full and subsyndromal PTSD. Exposure to the dust cloud (OR=1.36), performing search and rescue work (OR=1.29), and work support (OR=0.89) were additionally associated with subsyndromal PTSD. Rates of comorbid depression, panic disorder, and alcohol use problems (ORs=3.82-41.74), and somatic symptoms and functional difficulties (ORs=1.30-1.95) were highest among police with full PTSD, with intermediate rates among police with subsyndromal PTSD (ORs=2.93-7.02; and ORs=1.18-1.60, respectively). Police with full and subsyndromal PTSD were significantly more likely than controls to report needing mental healthcare (41.1% and 19.8%, respectively, versus 6.8% in trauma controls).


These results underscore the importance of a more inclusive and dimensional conceptualization of PTSD, particularly in professions such as police, as operational definitions and conventional screening cut-points may underestimate the psychological burden for this population. Accordingly, psychiatric clinicians should assess for disaster-related subsyndromal PTSD symptoms in disaster response personnel.
