(A) Polygenic risk score (PRS) of the addiction-rf
predicts lifetime alcohol (AUD), cannabis (CUD), opioid (OUD), tobacco (TD), and
cocaine (CoUD) use disorders, and variables representing more than one lifetime
substance use disorder diagnosis vs no SUDs diagnosis (Polysubstance Use
Disorder, 2 level), more than one lifetime diagnosis vs. one lifetime diagnosis
(polysubstance vs. unitary), as well as any substance use disorder diagnosis
(Any Addiction) in an independent sample (Yale Penn 3; N=1,986 individuals of
European genetic ancestry). (B) The addiction-rf PRS was
associated with a comparable phenotypic substance use disorders (SUD) common
factor in the Yale-Penn sample. Controlling for age, sex and 10 genetic
principal components of ancestry, all path estimates are fully standardized.
Estimates were significant at p < .001 of a two-sided test (LAVAAN does
not report P-values lower than .001).
