ABSTRACT
BACKGROUND:
Individuals with posttraumatic stress symptoms (PTSS) use a variety of safety behaviors strategies intended to prevent, avoid, or manage distress in anxiety-provoking situations. However, when used in the absence of threat, safety behaviors maintain PTSS by preventing collection of disconfirming evidence about potential danger. Thus, individuals with PTSS may benefit from eliminating their maladaptive safety behavior use.METHODS:
The current study evaluated a brief, computer-based safety behavior reduction intervention, Safety Behavior Elimination for Traumatic Stress (SBETS). Seventy-five participants were recruited based on trauma exposure and elevated PTSS. Participants were randomly assigned to the SBETS condition or a physical health control. In the intervention, participants selected two behaviors to reduce or eliminate over the coming month. Participants were given reminders to reduce those behaviors twice a week, and treatment outcomes were assessed at two weeks and one month following the intervention.RESULTS:
Hierarchical regressions demonstrated that while participants in the two conditions did not differ in their reported safety behavior use at follow-up, individuals in the SBETS condition reported significantly lower month 1 PTSS (Cohen's d = 0.56). While week 2 safety behavior use and week 2 negative affect did not mediate the relationship between treatment condition and month 1 PTSS, this relationship was fully mediated by week 2 use of the two behaviors selected for elimination.LIMITATIONS:
The current study was limited by its homogenous sample and brief follow-up period.CONCLUSIONS:
Results suggest that SBETS has a significant effect on PTSS, and may represent an acceptable, accessible treatment option for trauma survivors.Palavras-chave
