“…Items are rated on a 5-point frequency scale, ranging from 0 (not at all) to 4 (extremely), via 1 (a little), 2 (moderately) and 3 (very much). The scoring distinguishes 3 subscales: an avoidance subscale (items 5,7,8,11,12,13,17,22), a memory intrusion subscale (items 1, 2, 3, 6, 9, 14, 16 and 20) and a hyperarousal subscale (items 4, 10, 15, 18, 19 and 21). Scores are ob-tained by summing the responses for each item.…”
