Abstract

The current study used data from two longitudinal samples to test whether self-regulation, depressive symptoms, and aggression/antisociality were mediators in the relation between a polygenic score indexing serotonin (5-HT) functioning and alcohol use in adolescence. The results from an independent genome-wide association study of 5-hydroxyindoleacetic acid in the cerebrospinal fluid were used to create 5-HT polygenic risk scores. Adolescents and/or parents reported on adolescents’ self-regulation (Time 1), depressive symptoms (Time 2), aggression/antisociality (Time 2), and alcohol use (Time 3). The results showed that 5-HT polygenic risk did not predict self-regulation. However, adolescents with higher levels of 5-HT polygenic risk showed greater depression and aggression/antisociality. Adolescents’ aggression/antisociality mediated the relation between 5-HT polygenic risk and later alcohol use. Deficits in self-regulation also predicted depression and aggression/antisociality, and indirectly predicted alcohol use through aggression/antisociality. Pathways to alcohol use were especially salient for males from families with low parental education in one of the two samples. The results provide insights into the longitudinal mechanisms underlying the relation between 5-HT functioning and alcohol use (i.e., earlier aggression/antisociality). There was no evidence that genetically based variation in 5-HT functioning predisposed individuals to deficits in self-regulation. Genetically based variation in 5-HT functioning and self-regulation might be separate, transdiagnostic risk factors for several types of psychopathology.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
