ABSTRACT
Inflexible negative trauma-related cognitions are a common consequence of trauma exposure and an important indicator of posttraumatic stress disorder. One common measure of trauma-related cognitions is the 36-item Posttraumatic Cognitions Inventory (PTCI; Foa et al., 1999). Recently, a nine-item abbreviated version was developed (PTCI-9; Wells et al., 2019), which may be a reliable alternative with improved model fit. The present study examined the latent factor structure of the PTCI and PTCI-9 in a sample of 185 treatment-seeking outpatients with traumatic stress symptoms to replicate and extend initial findings on the psychometric properties of the PTCI-9. Using confirmatory factor analysis, the correlated three-factor model of the PTCI-9 demonstrated excellent model fit at Time 1 and Time 2 (6 weeks later), as well as strong internal and test-retest reliability. It also exhibited configural, metric, and scalar invariance across time. The present study replicated previous findings that the PTCI-9 may be a psychometrically sound alternative for measuring trauma-related cognitions.
