title: Reduction of cognitive concerns of anxiety sensitivity is uniquely associated with reduction of PTSD and depressive symptoms: a comparison of civilians and veterans.
abstract: PTSD and comorbid depression are common among civilians and veterans, resulting in substantial impairment. Anxiety sensitivity (AS) may be a common malleable vulnerability factor for PTSD and depression. The AS cognitive concerns subscale is most strongly related to symptoms of PTSD and depression, and thus, may be an efficient route to reduce these symptoms. The current study evaluated a brief computerized intervention targeting AS cognitive concerns. Specifically, we evaluated whether reduction in AS cognitive concerns was associated with reduction in symptoms of PTSD and depression. Also, we evaluated whether there was a significant difference between civilians and veterans in response to the intervention. The single session intervention utilized psychoeducation and interoceptive exposure to target AS cognitive concerns. This intervention was compared to a health information condition among a sex-matched sample of civilians and veterans with elevated AS cognitive concerns (N = 56). Reduction in AS cognitive concerns over one month was uniquely associated with reduction in PTSD and depressive symptoms in the same time frame. There were no significant differences between civilians and veterans in response to the intervention suggesting the intervention has efficacy for both groups. Treatment implications are discussed.
