Posttraumatic stress disorder in callers to the Anxiety Disorders Association of America.

We surveyed callers to the Anxiety Disorders Association of America (ADAA) with posttraumatic stress disorder (PTSD) and subthreshold PTSD (SPTSD). Most subjects heard about ADAA through media referrals and were satisfied with the service given by the association. The most frequent requests were for written information, learning how to cope with anxiety, and access to a local support group. Among callers, rates of PTSD (n=80) and SPTSD (n=111) were 8.0% and 11.1%, respectively. PTSD or SPTSD subjects were more likely to be younger, female, and with lower income than their no-Axis I psychiatric disorder controls (NAC) who had been exposed to trauma. In addition, they presented with more history of trauma, especially violent trauma, psychiatric comorbidity, recent psychotropic use, and side effects. More medical comorbidity, increased health service use, and reduced work productivity were also found among the PTSD and SPTSD subjects. SPTSD subjects were comparable to PTSD subjects on most of the measures with a few exceptions (more likely to be married, to have less psychiatric comorbidity, less medication use for mood and social fear, and fewer sedation and sexual side effects, and to have less health service use and work impairment). In conclusion, callers to ADAA with PTSD were particularly impaired and used the health care system extensively. Although the SPTSD subjects were not as impaired as those with PTSD, they were disadvantaged in many ways. Copyright 2004 Wiley-Liss, Inc.
