PTSD Symptom Scale—Interview (PSS-I; Foa, Riggs, Dancu,& Rothbaum, 1993). The PSS-I consists of 17 questions that correspond to the DSM-IV-TR PTSD symptoms. Symptoms were assessed with respect to the preceding 2 weeks or, if shorter, the time since the assault. Answers of participants were rated on a 4-point scale (0not at all, 1 once per week or less/a little, 2 two to four times per week/somewhat, 3 five or more times per week/very much). Scale scores were computed as the mean of the underlying items. Foa et al.(1993) report a test–retest reliability of .80, an interrater reliability of.97, a sensitivity of .88, and a specificity of .96 for the diagnosis of PTSD. Internal consistency in this study was high, ranging from .84
to .91 for Time 1 to Time 4.
