| Other information about tool (e.g., additional psychometrics [NPV, PPV, Youden’s index, diagnostic odds ratio]) | The CAPS demonstrated good interrater (intraclass correlation coefficient [ICC] = .92) and test–retest (ICC = .84) reliability. For the 179 patients interviewed by the trained social worker, the CAPS coefficient alpha was .92, and the item–total correlations ranged from .48 to .85. The two items with the lowest item–subscale correlations were “inability to recall important aspects of the trauma” (.47) and “restricted range of affect” (.52). Sub-scales: Reexperiencing (cluster B: items 1–5): Coefficient alpha .91; Corrected item − total correlation .69–.84 Avoidance and numbing (cluster C: items 6–12): Coefficient alpha .87; Corrected item − total correlation .47–.73 Hyperarousal (cluster D: items 13–17): Coefficient alpha .86; Corrected item − total correlation .56–.75 |

| Notes when administering the tool | Tool was translated and back-translated for use among Cambodian refugee populations in the United States. Weathers and associates (2001) suggested the following score categories: 0–19: asymptomatic/few symptoms; 20–39: mild PTSD/subthreshold; 40–59: moderate PTSD/threshold; 60–79: severe PTSD symptoms; and > 80: extreme PTSD symptoms. |
