1

Variables refer to the Visual Analogue Scale (VAS) ratings (0-100 scale), provided immediately following each script cue exposure.

2

Components represent residualized difference scores when ratings to neutral script cues were subtracted from trauma or substance script cue ratings. Residualized scores represent the difference after variance associated with the baseline score is removed. The VAS item, “avoid consuming substance,” was omitted from both models as it showed communalities of less than 0.2.
