Objective: PTSD is often associated with heightened physiological reactivity during fear conditioning procedures, but results vary across studies. The present study examined whether anxiety sensitivity (AS), or the fear of arousal-related sensations, strengthens the relationship between PTSD symptoms and skin conductance responses (SCR) during fear conditioning and extinction. Because gonadal hormones implicated in fear learning processes fluctuate across the menstrual cycle, the stability of these relationships in women was examined in two distinct menstrual cycle phases. Method: Thirty-two trauma-exposed women with (n=16) and without PTSD (n=16) completed the Clinician-Administered PTSD Scale, Anxiety Sensitivity Inventory, and a fear conditioning and extinction paradigm during the mid-luteal (mLP) and early-follicular (eFP) menstrual cycle phases. Results: In the mLP, stronger SCR to stimuli paired with shock (CS+) during fear acquisition significantly predicted greater PTSD symptoms only when AS was high and after removing an outlier. This appeared driven by effects on Numbing and Hyperarousal symptom clusters. Other hypothesized interactions between AS and CS responses were not significant. However, in the eFP, differential SCR between the CS+ and CS- during extinction predicted significantly greater PTSD symptoms, and there was a trend for this effect being stronger as AS increased. Conclusions: Results offer preliminary evidence that high AS contributes to a stronger relationship between physiological responses during fear acquisition and PTSD symptoms, at least among women in the mLP. Further research investigating the impact of individual differences in traits such as AS on the relationship between conditioned fear responses and PTSD symptoms is warranted.

Background/Objectives One-half of all U.S. adults will experience at least one traumatic event, and of those, approximately 11% develop posttraumatic stress disorder (PTSD) symptoms. Despite efficacious treatments for PTSD, one-third of people diagnosed still express symptoms after treatment.Thus, it is important to identify underlying factors that may be associated with PTSD symptom clusters to improve treatment efficacy. One potential factor is anxiety sensitivity (AS), or “the fear of fear,” and includes three different subfactors: physical, cognitive, and social concerns, yet few studies have examined this association using the Anxiety Sensitivity Index-3. Method Participants included 65 undergraduate students from a Southeastern University who were elevated on anxiety sensitivity cognitive concerns and experienced at least one traumatic event. Participants completed measures of trauma exposure, anxiety sensitivity, posttraumatic stress symptoms, and suicidal ideation. Results Results revealed that AS physical symptoms had the most robust association with potential PTSD symptoms and individual PTSD symptom clusters with the exception of the avoidance and numbing cluster Conclusions These findings may help clarify the nature of the relationship between PTSD symptoms and AS using the most updated measure of AS (ASI-3).
