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.
