Predicted PDS sum scores for the lower and upper quartiles of the Appetitive Aggression Scale score (AAS) and number of self-experienced event types, depending on group membership
Non-abducted group
self-experienced event types
AAS Lower quartile = 4 Upper quartile = 7
Lower quartile = 4 3.9 6.1
Upper quartile = 25 0 (−0.2) 5.5
Abducted group
self-experienced event types
AAS Lower quartile = 9 Upper quartile = 13
Lower quartile = 7 6.7 9.8
Upper quartile = 38 0 (−0.3) 6.3

Note. The fitted PDS sum score for the lower quartile SET and upper quartile AVE in the abducted group falls below 0, which is a result of the underlying model; i.e. one would expect no trauma symptoms (“0”) in these participants.
