Reductions in anxiety sensitivity cognitive concerns prospectively mitigate trauma symptom development

Area of Science:

• Psychology
• Trauma Studies
• Clinical Psychology

Background:

• Identifying pre-trauma risk factors for posttraumatic stress disorder (PTSS) is crucial for prevention.
• Anxiety sensitivity cognitive concerns (ASCC), the fear of psychological incapacitation due to anxiety, is a potential risk marker.
• Previous research suggests ASCC interventions may mitigate PTSS, but this requires formal testing.

Purpose of the Study:

• To investigate if a Cognitive Anxiety Sensitivity Treatment (CAST) administered before a trauma analog reduces subsequent posttraumatic stress symptoms (PTSS).
• To determine if reductions in anxiety sensitivity cognitive concerns (ASCC) mediate the effect of the intervention on PTSS.

Main Methods:

• Participants were randomized to either a CAST intervention or a physical health education control group before a trauma film.
• Anxiety sensitivity cognitive concerns (ASCC) and film-specific PTSS were assessed post-intervention and one week later.
• Mediation analysis was used to examine the role of ASCC in the intervention's effect on PTSS.

Main Results:

• The CAST group reported significantly lower ASCC and week-one PTSS compared to the control group.
• Reductions in ASCC fully mediated the relationship between the CAST intervention and reduced follow-up PTSS.
• The findings support ASCC as a malleable risk factor for PTSS.

Conclusions:

• Reducing anxiety sensitivity cognitive concerns (ASCC) prior to an analog trauma exposure can effectively mitigate the development of posttraumatic stress symptoms (PTSS).
• This study establishes ASCC as a causal risk factor and supports the use of ASCC-focused interventions for individuals at risk of trauma exposure.
• The findings highlight the potential of CAST as a preventative strategy against PTSS.
