The phenotypic link between AUD and future suicidal ideation was paralleled by the association between problematic alcohol use PGS and suicidal ideation, possibly suggesting that part of the phenotypic association is driven by shared genetic risk. Overall, the present study finds partial support for the notion that behavioral stage-based addiction phenotypes, as operationalized here, may not only reflect putative alcohol-related behavioral consequences but also developmental risk for AUD.
