“…Consistent with research suggesting physical and mental incapacitation concerns are most consistently linked to symptoms of PTSD among traumatized adults (e.g., Feldner et al, 2006;Lang et al, 2002), the disease, unsteady, and mental incapacitation concerns factors, along with the global index of AS, were expected to relate positively to posttraumatic stress levels in the current sample of youth. Finally, in an effort to examine the unique association between AS and trauma symptoms, the incremental predictive validity (Haynes & Lench, 2003) of AS was examined relative to several factors associated with posttraumatic stress levels among youth, including gender (Kilpatrick et al, 2003), age (Kilpatrick et al, 2003), and time since traumatic event exposure (Zatzick et al, 2006). Further, in light of empirical evidence linking negative affectivity, or the temperamentally-based proclivity for experiencing negatively valenced affective states (e.g., anger; sadness; anxiety), to trauma symptoms among youth (e.g., Weems et al, 2007), this factor also was included as a covariate.…”
