Groupings:
(1) intrusion subset: 1, 4, 5, 6, 10, 11, 14
(2) avoidance subset: 2, 3, 7, 8, 9, 12, 13, 15
intrusion subscale =
= SUM (points for comments 1, 4, 5, 6, 10, 11, 14)
avoidance subscale =
= SUM (points for comments 2, 3, 7, 8, 9, 12, 13, 15)
total impact of event scale =
= (intrusion subscale) + (avoidance subscale)
Interpretation:
• minimum total score: 0
• maximum total score: 75
• The higher the score the greater the impact of the event.
• High scores on the impact of event scale after an event or injury is predictive of psychiatric morbidity and the post-traumatic stress disorder at 6 months after the event.
