%X The literature on the utility of self-report instruments in determining caseness for posttraumatic stress disorder in South Africa is sparse. We administered the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders每Research Version and the Posttraumatic Stress Scale每Self-report version to a sample of 500 South African community members seeking HIV testing. Of our original sample of 500, 306 (61.2%) reported an index event for posttraumatic stress disorder and 25 (5.0%) met the criteria for this diagnosis. The Posttraumatic Stress Scale每Self-report displayed internal consistency of .95 as measured by Cronbach＊s alpha. Using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders as a gold standard, we conducted receiver operating curve analysis among the 306 participants who reported an index traumatic event to determine the extent to which the Posttraumatic Stress Scale每Self-report as a screening instrument successfully discriminated between participants who did and did not meet the diagnostic criteria for posttraumatic stress disorder. The Posttraumatic Stress Scale每Self-report yielded sensitivity of .76 and specificity of .78, with an area under the curve of .837. Positive and negative predictive values were .24 and .97, respectively. Our findings suggest that the Posttraumatic Stress Scale每Self-report may be effectively used to screen for posttraumatic stress disorder among community samples, including persons seeking HIV testing
