| Popis: | Most research on posttraumatic stress disorder (PTSD) relies on clinician-administered interview and self-report measures to establish the presence/absence and severity of the disorder. Accurate diagnosis of PTSD is made challenging by the presence of symptoms shared with other psychopathologies and the subjective nature of patients' descriptions of their symptoms. A physiological assessment capable of reliably "diagnosing" PTSD could provide adjunctive information that might mitigate these diagnostic limitations. In the present study, we examined the construct validity of a potential psychophysiological measure of PTSD, that is, psychophysiological reactivity to script-driven imagery (SDI-PR), as measured against the current diagnostic "gold-standard" for PTSD, the Clinician-Administered PTSD Scale (CAPS). Convergent and predictive validity and stability were examined. Thirty-six individuals completed an SDI-PR procedure, the CAPS, and self-report measures of mental and physical health at their initial visit and approximately 6 months later. SDI-PR and the CAPS demonstrated excellent stability across measurement occasions. SDI-PR showed moderately strong convergent validity with the CAPS. After adjusting for self-reported depression, predictive validity for the CAPS, with regard to health sequelae, was reduced, whereas it remained mostly unchanged for SDI-PR. Findings support SDI-PR as a valid and stable measure of PTSD that captures a pathophysiologic process in individuals with PTSD. Results are discussed with regard to the research domain criteria framework. |
