Safety behaviors are core cognitive and behavioral components involved
in the onset, maintenance, and treatment of anxiety-related disorders.
Yet, these behaviors remain understudied in the context of posttraumatic
stress disorder (PTSD). This may be due, in part, to the lack of
psychometrically valid instruments designed to evaluate safety
behaviors, particularly those relevant to the diagnosis of PTSD.
Furthermore, there is an absence of PTSD-related safety behavior
measures with the brevity necessary for continuous measurement-based
care during treatment. Our research aims to investigate the psychometric
characteristics of the newly formed PTSD scale of the Safety Behavior
Assessment form (SBAF-PTSD) through three studies. The first study
examined SBAF-PTSD factorial validity via confirmatory factor analyses
(CFA), along with other psychometric properties. Results identified a
10-item bi-factor model that reflects a primary Safety Behavior scale
and a secondary, latent construct labeled SBAF-PTSD Social Index. The
newly revised SBAF-PTSD scale was then used in an effectiveness study to
investigate its clinical utility in the context of PTSD treatment. The
third study sought to generalize our results to non-clinical samples.
The results of the studies are discussed in terms of their implications
for the use of the new PTSD-SBAF measure.
