TABLE 3.

Mean (SD) understanding of polygenic risk scores for alcohol use disorder across the three conditions of the randomized controlled trial.

Condition	Mean (SD)	F-test
Control	7.86 (3.06)a	F (2, 322) = 11.96; p < 0.0001
AUD Edu	8.38 (2.62)b
PRS + AUD Edu	9.67 (2.79)a,b

Values that share a superscript are significantly different (adj. p < 0.01). ^aRefers to significant differences between the control condition and the PRS + AUD Edu condition. ^bRefers to significant differences between the AUD Edu condition and PRS + AUD Edu condition. Fourteen items were used to assess understanding of hypothetical polygenic risk scores for alcohol use disorder. Items were scored as correct or incorrect and summed to create an overall sum score. Range = 0–14.
