Abstract
Adverse childhood events (ACEs) contribute to the development of mood and anxiety disorders and substance dependence. However, the extent to which these effects are direct or indirect and whether genetic risk moderates them is unclear. We examined associations among ACEs, mood/anxiety disorders and substance dependence in 12,668 individuals (44.9% female, 42.5% African American/Black, 42.1% European American/white). Using latent variables for each phenotype, we modelled direct and indirect associations of ACEs with substance dependence, mediated by mood/anxiety disorders (the forward or ‘self-medication’ model) and of ACEs with mood/anxiety disorders, mediated by substance dependence (the reverse or ‘substance-induced’ model). In a subsample, we tested polygenic scores for the substance dependence and mood/anxiety disorder factors as moderators in the mediation models. Although there were significant indirect paths in both directions, mediation by mood/anxiety disorders (the forward model) was greater than that by substance dependence (the reverse model). Greater genetic risk for substance use disorders was associated with a weaker direct association between ACEs and substance dependence in both ancestry groups (reflecting gene × environment interactions) and a weaker indirect association in European-ancestry individuals (reflecting moderated mediation). We found greater evidence that substance dependence reflects self-medication of mood/anxiety disorders than that mood/anxiety disorders are substance induced. Among individuals at higher genetic risk for substance dependence, ACEs were less associated with that outcome. Following exposure to ACEs, multiple pathways appear to underlie the associations between mood/anxiety disorders and substance dependence. Specification of these pathways could inform individually targeted prevention and treatment approaches.

Extended data
Extended Data Fig. 1 Distribution of substance use disorder PRS by ancestry and substance dependence diagnosis status.
EA = European ancestry and AA = African ancestry.
Extended Data Fig. 2 Distribution of mood and anxiety PRS by ancestry and mood/anxiety disorder diagnosis status.
EA = European ancestry and AA = African ancestry.
Extended Data Fig. 3 Mood and anxiety trait loadings onto common genetic factor, AFR ancestry.
The common genetic factor was produced using GenomicSEM-0.0.5c from GWAS of each input trait shown in the diagram. Because African ancestry reference files are not provided with the GenomicSEM-0.0.5c suite, we used LD scores from the Pan-UK Biobank (https://pan.ukbb.broadinstitute.org 2020) to compute LD matrices and correlations. Analysis was then performed after filtering SNPs to include those with MAF > 0.01 in the 1000 Genomes African ancestry population (https://doi.org/10.1093/nar/gkz836). Values attached to arrows from Fg to trait represent loading of the trait onto the common factor. Values at the bottom represent residual variance in each trait that is unexplained by the common genetic factor. Standard error values are in parentheses. GAD2 = generalized anxiety disorder-2 scores; MDD = major depressive disorder; PTSD = posttraumatic stress disorder; BIP = bipolar disorder.
Extended Data Fig. 4 Mood and anxiety trait loadings onto common genetic factor, EUR ancestry.
The common genetic factor was produced using GenomicSEM-0.0.5c from GWAS of each input trait shown in the diagram. The GAD trait was constructed from three GWAS of anxiety-related traits that were jointly analyzed using MTAG (methods). Values attached to arrows from Fg to trait represent loading of trait onto the common factor. Bottom values represent residual variance in each trait that is unexplained by the common genetic factor. Standard error values are in parentheses. GAD = generalized anxiety disorder; MDD = major depressive disorder; PTSD = posttraumatic stress disorder; BIP = bipolar disorder.
Extended Data Fig. 5 Factor loadings for the adverse childhood events (ACEs) latent variable.
This measure comprised 10 variables that reflected participants’ experiences before age 13. All variables were dichotomized to ensure the same coding and equal weight among them. All 10variables loaded significantly onto a single ACEs latent variable, but fit was below acceptable ranges (RMSEA = 0.05, CFI = 0.86, SRMR = 0.07). Allowing the residuals of household substance use and household smoking to covary improved model fit considerably (RMSEA = 0.03, CFI = 0.96, SRMR = 0.05), with item loadings ranging from 0.16 (for no religious involvement) to 0.73 for physical abuse.
Extended Data Fig. 6 Factor loadings for the substance dependence latent variable.
The SD latent variable comprised DSM-IV SD diagnoses for alcohol, cocaine, opioids, tobacco, and cannabis. The five diagnoses loaded well onto a single factor (RMSEA = 0.09, CFI = 0.99, SRMR = 0.05), with all item loadings ≥0.69.
Extended Data Fig. 7 Substance use disorder trait loadings onto common genetic factor, AFR ancestry.
The common genetic factor was produced using GenomicSEM-0.0.5c from GWAS of each input trait shown in the diagram. Because African ancestry reference files are not provided with the GenomicSEM-0.0.5c suite, we used LD scores from the Pan-UK Biobank (https://pan.ukbb.broadinstitute.org 2020.) to compute LD matrices and correlations. Analysis was then performed after filtering SNPs to include those with MAF > 0.01 in the 1000 Genomes African ancestry population (https://doi.org/10.1093/nar/gkz836). Values attached to arrows from Fg to trait represent loading of trait onto the common factor. Bottom values represent residual variance in each trait that is unexplained by the common genetic factor. Standard error values are in parentheses.
Extended Data Fig. 8 Substance use disorder trait loadings onto common genetic factor, EUR ancestry.
The common genetic factor was produced using GenomicSEM-0.0.5c from GWAS of each input trait shown in the diagram. Values attached to arrows from Fg to trait represent loading of trait onto the common factor. Bottom values represent residual variance in each trait that is unexplained by the common genetic factor. Standard error values are in parentheses.
Extended Data Fig. 9 Factor loadings for the mood and anxiety disorders latent variable.
Including 8 psychiatric disorders (major depressive disorder [MDD], bipolar disorder, posttraumatic stress disorder [PTSD], generalized anxiety disorder [GAD], obsessive-compulsive disorder [OCD], social phobia, agoraphobia, and panic disorder) as indicators for a single M/AD latent variable demonstrated acceptable fit (RMSEA = 0.02, CFI = 0.98, SRMR = 0.13). All item loadings were significant and ranged from 0.11 for MDD to 1.00 for PTSD.
